Fast fd !
 

Acceleration tests of FD rotary RX7's (VBOX data only accepted) verified by RICE RACING.
Only will accept flat road runs, any downward slopes greater then ~1.5 degree's over the length of the test will be rejected
Ranked FASTEST to SLOWEST
A little background information on acceleration times in gear/s: To do half the time of a stock weight FD you need basically double the power (simple), if you can do it in 1/3rd of the time you need 3 times the power (simple again) and so on it goes..... In your VBOX log the distance taken to achieve the speed is also exactly half if you had half the time taken, thus double the power (see proven example at end of post) eg: double the power also equals double the acceleration (Longitudinal G force average) *IT ALL ADDS UP IN REALITY! real world testing!!!*. These test really do separate the bullshit (dyno sheets) from the reality of practical acceleration tests.SEE EXAMPLE TEST @ BOTTOM OF THIS POST

Still on old tires, and showing about 24psi boost on the VBOX, and ~330rwkw VBOX POWER

Tested at 1320kg run weight and 25 deg C ambient day, still doing boost learning procedure so there is a bit more in at this level and fuel mixture set rich to be on safe side.

Fact V's Fiction

Will put up some VBOX graphs when I get them off the lap dancer top

Here is the graph of the 2.26 second 90-140 test :) this car has a *massive* power band, not normally seen on genuine 13B road cars of this level of performance and speed!@ the word "response" does not do it justice! It builds one bar of boost at around 3400rpm in a transient test, and near its maximum boost setting well before 4600rpm and it does it even in the low gears which only take a second or two for 8000rpm, its fantastic..... best road car set up ever !@
http://img268.imageshack.us/img268/1341/226secvbox.jpg

Done. Hope it will convince you to post some data from current boost settings:302:

Steve E-Mailed me, thanks.

I did some power calcs on his ride! amazing machine. ~400+rwkw! on VBOX even have map proof of where he did his runs :auto:

That is a honest 650bhp 13B RX7 (1280kg as run total weight), sure its on C16 but its a street car FFS, he has done an amazing job of it.

100kmh to 200kmh in 5.16 seconds is gag factor to the max!!!! :coolgleamA:

http://img51.imageshack.us/img51/942...mancetable.gif

^ Only a Buggatti Veyron is faster than his RX7 road car :hurray:

Here is his official file run. Real road power included! 400+rwkw that is over 536rwhp! amazing stuff.

http://img687.imageshack.us/img687/3...smg144test.jpg

Wow great response........ to what is officially one of the fastest accelerating 13B RX7's in the world, better than everything other than a Buggatti Veyron!!!
:uhh:

Amazing!

I guess some posters here are too busy spaming the homo gay ass raping forum club to bother passing on some congrats to this bloke. Amazing! I wonder where everyone else's cars with FAKE CLAIMS of 500+rwhwp that have never ever seen a dyno let alone done an acceleration run are LOL.

Internet forums = gay! :piggy:

Anyway here is his set up taken off gayclub.com

i have never really posted any of my parts list anywhere i have no problem sharing though.

-built and ported motor by me. port is judge ito based and then extended out to my liking.
-a-spec billet 6765 kit with a 1.00 a/r t4 turbine and ported H cover for fancy sound.
-power fc tuned by me
-850/2000cc injectors
-dual walbro pump and a kenne bell boost a pump
-coolingmist 250psi pump with a c10 injector 800cc running 50/50 meth
-exhaust is 3" all the way back.
-exedy twin disk setup
-3 bar map sensor
-greddy profec s bc
-blitz fmic
-alum radiator

^ lol i guess its just been a quiet weekend...

nice finally a nice working set up

Dam i just came back to check on this. That is 1 hell of a setup makes a nice case for the PT series turbo

biggest advantage i noticed with the precision billet 67 is that the turbine wheel is a regular p-trim size but looks very similar to a garrett gt wheel. which flows better vs its size. most p-trim wheels i have seen fall off at anything over 25psi. this went up to 27psi no problem and making steady power at each psi level between 23 and 27. i would have taken it all the way until the turbo ran out of steam but i needed a bigger wastegate spring as i maxed out the boost controller. i currently have a 16psi spring in there. im going to move up to a 20psi wg spring over the winter and max it out next year. car is moving very well right now so going to have some fun for the rest of the season.

You could upgrade to this wheel http://honda-tech.com/showthread.php?t=2981656

Also you mentioned that your EGTs are increasing disproportionately in top end. Maybe better exhaust setup is what is needed.
Given that 67mm billet is proven to flow north of 90 lbs/min, you should have at least another 100 HP in there.

Its shame that most people don´t realize, that you have one of the most powerful street driven rotaries around. Reading today´s internet forums makes me think, that people forgotten why they are modifying cars at the first place. Why give credits to guy who have genuine 600+ HP 13B when there are dozens of monkeys which claim 700+ and never back it up?:nopity:

everyone is set on dyno numbers is the issue. most cars you see on the forums make 600+whp on my boost level. but does there car move down the road as fast? who knows. so since i posted up what it made which was 525whp on that perticular dyno it seems weak. there is actually a guy on the forum that just currently made 465whp with 370 tq on 15psi with a t04z which is a 67mm turbo. that is basicly impossible when you put the power down he will probably run the quater at 125mph trap. thats what i ran with 400whp. just the way it goes its a tuning tool. proving grounds are on the vbox or the dragstrip.

also as for the billet 67. it does flow crazy amount on the compressor side. issue is the turbine is fairly small for a rotary to make big power. i think its very well setup for a street car as i have full boost by 4k ish.. the gt style wheel precision came up with does help it flow better then a normal p-trim. there is also some gains on the exhaust but ill try the boost first and see what that does for next season.

Bumping best thread on here :party:

140mph road car!!!! :smash:

ok took it over to the track. here are the results.

60 ft 1.91
1/8 7.12
1/8mph 107.48
1/4 10.69
1/4mph 139.88

best run with clutch getting week.

60 ft 1.78
1/8 6.89
1/8mph 108.53
1/4 popped off a coupler would have been a 10.3-10.4 at 140.5-141mph.

then i blew the clutch completely looked like and automatic with a stall lol but still ran good

60 ft. 1.76
1/8 6.92
1/8mph 103.87
1/4 10.55
1/4mph 136.04

vids will be up shortly of in car an out. now im looking for a nice clutch setup for 650whp of so. i currently have a exedy twin disc. clutch is still good but not for a sticky track with hoosiers.

check this Fd from our uk forum there goal is over 1000bhp at there target boost

http://youtu.be/dWlEvYFMFwI

James Willday 771whp then the dyno shit it - Built and Tuned by Powergains UK nothing to do with me just thought i would show you guys what some of the UK lot are doing more info on www.fduk.org

Fact V's Fiction
 

Guess I could add my RICESP to this list :)

100kmh to 200kmh = 6.25 seconds.

BP Ultimate fuel, water injected. 1320kg run weight ~330rwkw VBOX power
~24psi *second lowest boost setting lol!*

90kmh to 140kmh = 2.26 seconds
100kmh to 150kmh = 2.39 seconds

Don't know of any faster? legitimate street RX7's running on Petrol only? but either way compared to the list of "supercars" I posted its right up there :willy_nilly:

Ha ha!

Funny in an ACTUAL VBOX test of a Buggatti Veyron the **** is NOT as fast as the factory claims LOL....... 15000 mile car apparently, either way. I think I might just be about to add another scalp to the RICESP super car destroyer ledger :fawk:

VW Buggatti nugger 100kmh to 200kmh in 5.9 seconds VBOX verified!

http://www.roadandtrack.com/tests/ca...on_16.4_page_3

Hmm, wow! I hadn't seen this thread until just now (saw the link in the newb(ish) thread about adding multiple ports to an engine). That's sickly fast for an FD!!!

Now to look into procuring a VBOX so I can see what my car is *actually* doing (when it runs... lol).

DO IT!

I wish more people would get real and buy a VBOX.

I am happy to run calculations for anyone who sends me their VBOX files ;) Hopefully we can start a trend of real testing :auto:

Cheers man,

Do you know how much the VBOX III runs? Honestly the only stuff I saw prices on were the driftbox and stuff like that...

First things first... Get my car out of the shop, then I'll look at picking one of these up.

I assume you need the actual weight of your car and all that stuff entered into the VBOX for an accurate reading?

I use a Performance Box by Racelogic (same company that makes VBOX). It is an external device that mounts to the windscreen via suction cups. Me and a buddy split the cost of the unit and use it to log our times when we do track events.

You can use it for the acceleration tests like RICE does, but I have yet to log one myself.

http://www.performancebox.co.uk/

One of my logs:
http://farm4.static.flickr.com/3081/...62439c62_b.jpg

^ Hmm... that seems very interesting. I bet you could also use that on a motorcycle... Does it have an internal power source, or do you have to connect it to a 12v in the car?


:edit: Also, will you be bringing this with you to DGRR? I'd love to snag it for a pull or two to see some solid data on how my car looks on paper!!

It uses the cigarette lighter for power

I had a VBOX III it was $22,000 from memory.
I now use a VBOX3i I can't remember the exact price but is around $27,000.

You don't need their top end unit though. Racing Beat use a VBOX II for chassis development (it's around $8,000 or so). But you don't even need to spend this amount.

I started out using a VBOX Mini > read here > http://www.ausrotary.com/viewtopic.p...66bc9be8914e1c

As I did more and more work I stepped up to the VBOX III then the VBOX3i with IMU unit and a whole host of other input boxes.

The VBOX Mini is copied in a hobby format in the Drift Box and Performance Box models, these are used 99% in the performance world *these are great products and do most of what you would ever need* These units from memory are sub $1000 or so. The VBOX Mini is around $2500.

These are THE reference measurement instruments across all vehicular platforms around the world and in so many testing labs, EOM's research centers etc etc ............ Buy a drift box or performance box it will be the best money you ever spend

Yes to calculate the power as I do (see here > http://www.riceracing.com.au/vbox-ii...ing-tuning.htm )

(I developed this formula from first principles myself) and use it on any RL .vbo or .dbn file to add a maths channel with power as the output (as I did for the dude with the fast fd)

http://www.riceracing.com.au/RICE%20DON%201.JPG

&

http://www.riceracing.com.au/RICE%20DON%202.JPG

you need to know the mass of the vehicle as run. I measure all the cars I test with my Tanner scale system.

Anyway read this > http://www.performancebox.co.uk/down...CHvPB_Test.pdf

And here is a good thread on Race Logic own site > http://www.racelogic.co.uk/Forum/showthread.php?t=727

Right on Peter,

I didn't realize they were that expensive! Lol, I went to the VBOX USA site and saw the capabilities sheets, but no pricing data. Now I know why! Lol

Will have to look into picking up one of those along with the new ecu this summer, lol

For $12 this application works amazingly well.

What did you enter for drivetrain loss? I'll just leave mine at 0.

I pretty much despise anything apple (except my ipod, but that's just for sleeping/working out anyway), so I might be needing to pass on that one unless I can get it for my droid by way of Verizon.

You're welcome

impressive numbers indeed :)

Yes indeed.

Why more people do not invest in racelogic products and do some testing instead of internet guesswork is beyond me.

:auto:

All this talk of racelogic got my attention. Think i might need to get my hand on one of those..

O.K.

I have a bit of a rare thing in the FD RX7 world of real road cars, a potential 4 way battle!!!

Docmar (from Greece) 31psi GT45/47 equipped 13B RX7 (recently dynoed 840?rwhp!) .. contacted him last night and magazine in Greece will be VBOX'ing his car soon! previously on 24psi it did very well indeed with two people in car.

smg944 (USA) already detailed here, looking to go true 93 octane set up, either way sick car! and a real credit to this one man band effort (engine, tune, the whole shit show done himself!)

RICESP (yes cunts that is me!) 33psi T04Z, probably lowest power of the lot, but legitimate pump 93 petrol fueled ;) and RR water injected. 100% stock standard engine, stock standard inter cooler!!!! < a real factory rotary powered exotic supercar beater

Ray Wilson's PFS customer 10,000jazzillion rwhp @ 22000rpm!!! Maybe will run a 93 octane test since he is a broke ass and cant afford to justify spending $500 on a base model VBOX :P

This will be a VBOX ONLY thread, all files *maybe video if you have it to go along* need to be forwarded to me for verification and we will run up the 100kmh to 200kmh times and see how they compare to iconic supercars across the globe!

Showing the world that real rotary street cars do exist and they are not like your local neighborhoods 1200rwhp Toyota Supra that traps 122mph in the 1/4 mile LOL.

if you know of any other fags who can get off their ass and be bothered to test their cars let me know, lets not just be a shit house forum full of dyno queens ...... get out there! test your car in a legitimate way, and prove that it works, and its FAST

Hello guys.
My Name is George i live in Greece and i am relatively new in rotary scene.
I have my fd for 4 years now, perhaps lucky for me or not, with the same motor.
This was my first ever touch with rotary motors.

You have to go easy with me because i never have learn english and i never had anything to do with something american or english or australian (exept one very nice australian-greek woman years ago).

So every thing that comes from me it is only what i'v learned from the tv (movies or music videos) from internet and from english books or magazines or from my effort generaly to learn english NOT with teacher only by my self.

I just LOVE my fd and it is by far the car that i use more and it gives me back so much pleasure so much joy concerning the fact that it isn't my first every day car however i use it allot i make big road trips with my wife and with my daugther.

I take it to cirquits for track days, i participate in rwyb drag races, i tune it by my self (biggest pleasure) in the open road, i tune it in dynos but i use it the most in open road at least once a week.

A car magazine in Greece will be VBOX'ing my car soon again and i will send the files to Peter.
I will use pumpgas because i will NOT use maximum boost for the test.
The car is very difficult to drive it in the road in maximum boost (31psi for me)
It looses traction even in third gear and 180km with very good tires (semis 265/35/18) in very good tarmac quality.
So i will try 24-25psi if i can manage the power and make something good out of it.

My every day boost is 20-21psi about 530-550whp (in different dynos)

I am very happy that i am mentioned honourably, far away from my country.(that happens not so often even in my country Greece)
Thanks to Peter because he is always seeking the better (forgive my english i do not want to sound cockie i do NOT think that i or my car are better) and he loves rx7.

Thats all from me for now,.....some videos with my car and me.

Keep it up...

I think the reason most people dont go down that route, is because they
1.see the price tag
2. have problems understanding the numbers and corrolations between the numbers, i myself is one of them, but i try to learn something every day. :)

So, lets say i was to put aside some bills one month and want to get a cheap and reliable Vbox-ish thing. Or, i get a few friends and get one we can share.
What do you recommend?

A few of my friends bought one, and they shared it for some street fun and also at use on track days too.

Honestly if you love your car and always are looking for improvements then a basic VBOX like smg944 has is worth more than paying for some other stuff you would on your car ;)

I recommend everyone buy one, if you can do it on your own by not spending so much on going out for a few months or drinking less beer, then its a worthwhile investment. They are such a great thing you very little of them for sale 2nd hand.

Just get one, we all here can teach you how to use it ;)

like this unit?

http://www.vboxaustralia.com.au/vbox%20mini.html

So that is the base model VBOX. Excellent unit which will allow you to do data logging with a mini input module hooked up to it as well (you can see a sample log screen on my web page - go to water injection page) I tuned the Capella listed there with this device! on the road!

Data captured on VBOX MINI + MIM01 Input module
http://www.riceracing.com.au/Photos/WI%20numbers.jpg

A cheaper unit/s is the hobby level PERFORMANCE BOX, see vbox usa web site for links to it, cant hook up extra inputs though, but still excellent for performance testing. site for you > http://www.vboxusa.com/store/index.p...=index&cPath=1

I have a performance box so I can go out and get some data this weekend...

I have only ever used the box for lap timing at the track so im unfamiliar with the 100-200 test. I assume you just record an acceleration run through all the gears then sort through the data and grab the time between 100-200... Not crusing at 100 then punch it until passing 200, correct?

My car is nothing special, just an FD with non-sequential twins running about 12psi.

I also have quite a few friends with single turbo cars locally so I can try and get it in their cars for more data.

Hi!
Excellent! I will have a look at this little thing.
So, if i get it and do some runs with it when im done with engine and tuning, and send the data to you, you can fiddle with numbers and stuff?

Damn you for getting me to look at this stuff, i love gadgets! I was to spend my money getting the 7 done this year...! :biggthumpup:
