280rwhp@9lbs of boost, stock turbo,stock ecu - Page 3

I did a 2.0 sec 60ft so that explains most of the e/t difference. I doubt the clutch was that bad or it wouldn't have gotten off the line so quick. It should be pulling 110 or so mph.

your not reading correctly, car had clutch issues from second gear on and almost to the finish line. clutch was an issue. and im thinking im wasting my time with you. just hang around and wait for updates..

Knowing Ito we will soon see 300HP with this same setup!!!...nice combo for a first gen

Mazdabater · 10-11-2011, 06:47 PM

Wait this engine is in a first gen? If so that makes me even more doubtful it's got 280hp. Also I don't know of any cars that have a problem with a clutch that only affects certain gears.

did u not see the youtube dyno link? it's a seies 5 turbo Rx7. what goopy means is, a set-up like this in a first gen rx7 would be a fun toy being a first gen is alot ligther..

I'm not sure what your problem is, from the beggining your insinuating that a stock ecu cannot achieve these goals, then you go on and on. For your information, I have dynoed over 327rwhp with a stock ecu over 10 years ago. and ran 11.7 with that same stock ecu in a series 4 turbo II..

not only did I post a dyno sheet but also posted a dyno video pull. i'm not here to brag but to show the potential involved with a simple set-up like this. I could even tell you on a 10lbs of boost pull my kid's car made 291rwhp. I didnt post 291rwhp because the engine went lean and that is not a realistic goal/tune..

the car made back to back 280rwhp @ 9psi of boost with the proper A/F ratio, and that jack is the facts believe it or not..

here i'll post some pics her clutch with tons of heat spots from slippage.. I hope you know how to read a slipping clutch.. so sit back relax and enjoy the progress on this simple but effective build..

Judge Ito · 10-11-2011, 06:52 PM

clutch should be fixed by tomorrow. and later in the evening out to Island dragway for some more practice runs..

RotorDad · 10-11-2011, 07:09 PM

Looking forward to see the progression of this car.

by tomorrow morning the new clutch should be installed and change fluids and leave it ready for the evening. i'll try to have some video footage..

Mazdabater · 10-11-2011, 09:03 PM

It seems incredibly unlikely that that's the real hp. I'm hoping you prove me wrong and I'm not having a go but I have seen so many hp claims that don't back it up at the track, and thats what this looks like, not so much concerned with the ecu, but I am aware of how inefficent the stock turbo is. And as for the clutch slip it cannot be that bad to do a 1.8 sec 60ft. Back to my 13.5 @104 on 220hp was with a 2.0 60ft, on a better track/tyres my 60ft time would be improved thus my et and mph would have changed.

At the end of the day if I see it pulling mid 12's at 110+ mph I'll shut my mouth and give credit where credits due as this is quite an achievement.

even if you improve to a 1.8 60 ft mark your car will NOT pick up half a second in the big end.. and your wrong again, when any car improves 60ft mark, the E.T. improves but the mph will not(basically the quarter mile is driven in a more efficient way) and if you think the clutch was not bad enough according to all the heat shown from slippage then you have very limited experience in the world of drag racing..

and your wrong again with saying it should trap 110mph, before you make any assessment, the weight/hp needs to be known. and in this case you DO NOT KNOW how much the car tips the scale with the driver.

according to the weight of the car and the 280rwhp the car should trap 106.22mph..

with 292rwhp it should trap 108mph

and with 311rwhp it should trap 110mph ofcourse any of this is assuming the car will have good traction and driven efficiently..

Mazdabater · 10-12-2011, 06:47 AM

I'm just assuming 60 more rwhp picking up more mph then my 220ho car. As for the weight my car is probably heavier then stock by a little bit and I weigh 106kg so I doubt your heavier. As for mine taking .2 off my 60ft would probably take .4 or so off my et putting me at around a 13.1 and I'm sure it could have hit 1mph extra with some extra traction. Also if your clutch is that fucked you should even gain some rwhp on the dyno with a new one. I'm still not able to see 280hp. And picking up an extra 11rwhp gain going to 10psi on the stock turbo seems incredible to me given how inefficient they are up high.

Mazdabater · 10-12-2011, 06:48 AM

And we are both flogging dead horses here I'll just shutup and wait for the results next time at the strip.

My5ABaby · 10-12-2011, 07:45 AM

There's a dyno and video posted... I'm not sure where the massive doubt is coming from.
