Test it, lets build up some data base of FAST FD's
 

100% right.

There are two tests that are great to do:

90kmh to 140kmh (3rd gear power band test (Rice Racing standard) you will see the under my VBOX page)
*** This is a VERY POPULAR test as its fast, very quick, easy to do, and lets you test the power band from ~4500rpm to ~8000rpm (depending on level of wheel slip!)*** http://www.riceracing.com.au/vbox-ii...ing-tuning.htm

100kmh to 200kmh (3rd gear to 4th gear to 5th etc, acceleration test)
Note: in the acceleration test, say if you have a poor power band you can start off in 2nd gear, its totally up to you, whatever makes your car faster, you can change up to 5th if your car wont rev out, its up to you! ;)

To do either one you find a flat bit of road, start in gear a fair way under the set speed (say 70kmh), mash the gas, and run it out over the end speed (say 220kmh). The data is extracted post processing using the VBOX Tools software, and a report is generated (just like show in my VBOX testing page on my site.

If you boys go the extra level of getting an accurate weight measure of you cars (with you in it as when you run the car) I will then apply my own developed formula and create another maths channel on your data log you send me, this will be a power channel and it will show you the power at the rear wheels during your runs *simple* It is a great way to see what power you have, and make on the road during the test. I will do this for everyone who sends me a file. The results will be collated in the first page/post of this thread and we can have a resource for people to look over and easily compare & ANYONE can spend a little amount of money and go buy a Performance box and run their own tests and send me the files and get amongst the action and fun that is testing your car and finding out exactly how powerful and FAST it really is :)

This is ONE device that WILL help you quantify the money you spend on your car and will show you how powerful and fast your car really is, be it on circuit track, or air port runway, drag strip or on the street, its a great investment, and separates the FACTS from FICTION :)

Yes for free for ANYONE I will run the extra data channels and reports on their files they send me, it makes me happy that rotary people are out there testing and learning and showing off their cars the way it was intended, to be FAST on the road and track and showing what they can do, and this way there is no excuses, no doubts, just pure simple factual results, the BULLSHIT STOPS WHEN THE VBOX DROPS. :)

Someone needs to recruit this man from Finland to sign up here and join us who have fast RX7's :) we can help him much much more than poofters on uselessclub.com ;)

First page updated! with some results & stats

Man, i think i will have to get me one of theese, if a friend of mine doesnt have one allready..! Damn you, Peter!!!! :D
I am dead curious on how fast my car will be when im done. I will be running practically identical setup with the BNRs in seq mode and the awesome 100psi simplified solenoidkit from azeknightz, to Yellow_r1 in this thread, but only water injection for me.

http://www.rx7club.com/showthread.php?t=966671&page=2

It is the ONLY honest and simple quick way to know how fast you car is.......... Test the power band (3rd gear test) test the std 100kmh to 200kmh sector and see how you compare to others and to Iconic Supercars across the globe :001_005: not many limitations nor excuses :icon_tup:

Get On It :-oc==3

Look forward to adding you to the list :)

Please send me your file to peter@riceracing.com.au along with some details of the weight as tested (if you know) I'll run the power channel and send you the file back ;)

Here is a picture of my old VBOX units, my VBOX3 and my VBOX Mini + MIM01 input box next to it.

I LOVE THIS UNIT!!!

dont even dare think about the costs of that equipment :ack2:
Bet it cost more than most well done FDs :biggthumpup:

I found the v-box test of my car in the power magazine.

I remember 21-22psi pump gas, about 1/2foul tank, me and one fellow passenger from the magazine and the equipment ofcourse.

100-200km 6,9sec.

I am very anxious to see the difference from the extra boost and power....:suspect::suspect::suspect:

And without passenger in the car....:suspect::suspect::suspect:

updated!

Thanks for supporting this list ;) it will be a great thing :) a resource to separate fact from fiction :9898:

Science hits the hype world
 

More technical details added to the bottom of the first post to explain to people when you have the same car with same weight then to do half the time of a stock car you need double the power! this also equals double the acceleration you record on a VBOX! (double the power equals half the time and half the distance to reach your speed increments be they 100kmh to 200kmh or 90 kmh to 140 kmh)

So in reality everything adds up perfectly :)

This is how I test average power increases on cars, making TRUE power gains not just at the peak last 500rpm but across the whole range :) more like 4000rpm

We can compare all kinds of cars and set ups, at the end of the day its all about how fast your can accelerate and how short a distance, least now you boys can see the facts behind really proven fast fd's :cheers2:

You will get there mate, least now you can compare to various other proven FD's around the world (the whole idea of using a VBOX and this list).

Remember F=m*a, so extra weight has an effect especially at lower speed tests like 90-140, at higher speed aero dynamic drag force plays by far the biggest part (Bugatti anyone!) there is no substitute for power and average power in the gars you choose.

100kmh to 200kmh is a fantastic practical test, and no shortage of real supercars to compare yourself with too. You may not want to do the power band test in 3rd gear though with your massive turbo, it will show up the lack of low end power and response. I will run the report anyway and post it up so people can see the effects. Again on my site the Capella on the VBOX testing page performs very badly from 4700rpm to 8000rpm in 3rd gear (over a second slower than my car).... too big a turbo and wrong porting for those revs on the street.

I fixed up some formatting on the first page, so its easier to follow for people.

Added a VBOX test of a Ferrari F40 (euro spec) this is just out of general interest as its the iconic supercar of all time! I built my RICESP to beat the Ferrari F40, which it easily does ;) as can be seen, Ironically the run weight is IDENTICAL, the cross sectional frontal area is the same, as is the Cd, so you cant get a more even comparison, they even have the same gay rear wing and are red lol.......

http://img444.imageshack.us/img444/1467/f4001.jpg

Anyway I hope this inspires people to get on with maybe purchasing a Performance Box and getting out there and doing some tests and getting to know for yourself once and for all how fast your car is going with your improvements you have done :dunno: :) after all there is nothing more satisfying than seeing with your own eyes the fruits of your hard work and money spent to make your rotary powered car a supercar crusher :reddevil:

Get On It people, start testing, send me those files and some specs of your FD and we will hopefully ad to this real quick with your own cars :302:

And this is a slow lard arse *car only weight* USA spec Ferrari F40 I had corner weighted and VBOX tested by its owner, 60-130 time, these make a bit less power (closer to the factory 478bhp rating) than the cat less EURO light weight cars! anyway around 1450kg run weight full fuel inc driver
I easily beat that car, then went on to take down the much faster EURO spec F40's (which also went down!) *the faster EURO one is listed on our 100kmh to 200kmh test list*

Bit of info on Ferrari F40 engines here > http://www.carobu.com/Project%20Cars...40_Article.pdf inc tuning AFR on engine dyno ;)

& http://www.carobu.com/Project%20Cars/F40.html

MAKES YOU REALLY WONDER, HOW A HEAVIER CAR WITH LESS POWER, SAME AERO LOAD (Cd & AREA) SAME GEARING FROM 100KMH TO 200KMH (I SHIFT ON MANUAL BOX) CAN BE ALLOT FASTER THAN THE PRETENDERS WITH 500RWHP, 600RWHP, 700RWHP AND SO ON lol :) AND THESE CUNTS RUNNING LIGHTER CARS TOO!

FACT V'S FICTION

http://www.carobu.com/Dyno%20Testing...iles-Graph.gif

Type:3.0/4v
Bore: 82 mm
Stroke: 69.5 mm
Compression Ratio: 7.7:1
Heads: stock (no flow chart)
Cams: std. factory grind
Induction: twin LM turbo/intercooled with Weber-Marelli injection (Razzo Rosso chip set), electronic waste-gate, standard air box and filter
Exhaust: factory 4-1 headers with LM pipes
Ignition: direct coil

This engine was tested as-is from the car, then upgraded with our LM turbo kit. This engine wasn't particularly fresh, but was representative of an average F40 engine.

Bill S from Ferrari chat who is the owner of many mega cars :bowdown: posted up for me his 100kmh to 200kmh time from his Ferrari Enzo, this thing is a probably a bit stronger than normal tested ones since he did a precision rebuild on the engine. Thanks very much Bill! added it to our list, here is the link to the graph, when he sends me a cleared version I'll upload it and post here too. http://www.ferrarichat.com/forum/sho...#post141406422

First page updated, format tidied up, and links put next to tested rides for further information :D :bigear:

Expecting more results from people maybe this weekend, I'll post them up :smash:

Weight and Power *important to see how fast you can accelerate*
 

http://www.ferrarichat.com/forum/sho...246690&page=10

^ Great link for actual measured car weights of iconic super cars :driving:

Every time i look at the thread i see updates.
Every time i find it different and better.

I am very anxious to make the test with my car, to see the results and to see also other strong fast fd's.

PS i think i am going to use some water to my motor....

peter has done a nice job with this thread. i sent him over another 4 rx-7 setups to compare to with specs.

Thanks very much boys, and steve I got all the files just now, I'll process and post them inc your power request tonight my time.

Keep up the great work with testing, and this will grow very quick ;)

I love the list, but we need to get a few modded supercars on there to see what the insane power looks like. There are plenty of TT lambo's and Ferrari's around (underground racing, and about 4 other companies specialize in them).

I can throw in one or two I guess, just have to keep it in perspective, I want to keep the list to FD RX7 road cars (for obvious reasons of comparison ability and validity) so pretty much the only variables are how much power you have in reality and the spread of your power curve (in the 90kmh to 140kmh test in 3rd gear).

We also need to remember the majority of cars are little 2.6lt *equiv* 2 rotor rotary engines, compared ti many more cubes and multiple turbo's off cars that cost 10 times more in price. I have a few reference "super cars" up there, but dont want to spam it too much with all kinds of stuff that makes it hard for people to follow etc.

I could easily link 6 speed's forum to show those other cars though if people want to look them up :) *idea*

Open to all opinions though, that is just my thoughts on it. :bigear:

Is this referring to me? lol


Well, hopefully I'll have my car back in a week or two and once I sell my 600cc sport bike I'll have a bit of spare cash to buy a Driftbox or Performance box... Once I get everything fitted and working I'll kick you whatever files I log :biggthumpup:

Nah it was that blue 800rwhp RX7 where Ray Wilson was shitting on about it after I told him I don't give a fuck about his dyno sheets, and he sprouted on and on about how good he is and his motor is refined etc etc.

I put the challenge up, ball is in his court to test the car and prove if its a fast fd or just another dyno queen.

:lurk5:

ok I get it. making an rx7 comparison is a nice idea. The other cars would muddy it up, as displacement is king (if all mods are the same and sized correctly). But a few wouldn't hurt just to see if you have access to them.

Let me know if you end up picking one of those up. I'd like to run my slow rotary too :lol:

Ah, I gotcha. Yeah, I know the car you're talking about. How long ago is this that you had that conversation?

The reason I ask is that it's now left his shop, so there would really be no way floor him to test it. Truth be told that one was very well put together with little to no expense spared.

Mine should be coming put of the same shop making about 500whp shortly. I'd be happy to do the testing and you can use those files as a baseline for comparison.

Honestly if Ray is just some rotary hack a la HC/BDC than you're not likely to find anybody (shop wise) in the states who really knows their shit.

Oh, most def bud! I have no problem sharing toys :)

Peter,

I emailed you a performance box data file. :icon_tup:

Thanks John, file and detail received. I'll do the analysis tonight (my time) and post it up and send you back the file with the power channel added.

Peter

List updated, added a few more "normal" FD's that people can aspire too making themselves :auto:

Still very fast cars when you compare them to the list of real cars (used as a guide to measure yourself against). With a bit of fine tuning these are nice all round packages.

Keep up the great work, keep testing and sending me those files and details :coolgleamA:

I've been looking for a list like this for ages.

We (all who get off there ass to test!) are glad to provide what you want, its a bit of hard work for me to collate the info, but I enjoy it and it's showing what these cars can do in reality.

I'm sure with time, many more FD RX7's will be tested, so you can see how you compare with the various set up's and levels of tune up out there.

Bump this great thread

This is one of my favorite threads on the whole Internet. So i'm bumping it.

Update for you on page 1 100kmh to 200kmh from RICESP tested a few weeks back, fastest true petrol 13B RX7 in the world ;) well the only one proven anyway.

We have a few boys who are trying some more set ups who have sent me VBOX files, just need to get around to posting them up.

There are some vehicles being upgraded for higher power output too now that will see a reduction in times for these performance figures listed. You are right that this is the best thread on the internet, in a world where there is so much shit talk and internet posts there are some of us that have real cars, that work, and are really FAST :auto:

Fact v's Fiction LOL

Facet V's Fiction
 

Reminder this is the ONLY thread where the "majical internet claims of 500rwhp+" are actually backed up with a proper measure and not just a toilet paper digital screen dump (or worse still a sig block with a claim only LOL) like most forums and posters use to seller inferior offerings ;)

Challenge has been out there for a long time now................................

Seems like not too many can back the HYPE with FACT lol, would be nice to add some real street cars to this list to show just how good you can make them and how fast they really are.

Guess you have to make one first though hahahahahaha (or pay someone to do it for you) ;)

subs, Peter keep up with the good job. Kind of like the no BS approach.
