congratulations. i knew you could do it! i can't wait to get some more video of you running and hopefully breaking the 10.99 barrier

Wow! Very impressive.
Your engine is completely stock inside?

Which EMS are you using?

powerFC and yes i have seen the car engine is stock! i saw it before when it only 12's..... LOL

Scalliwag

That really rocks!

OK, I was just wondering, because Checkpoint recently made 400hp on stock twins with a Wolf EMS. Pretty impressive for a little 1.3L engine.

very very nice numbers

This is what we need to see more of !

MAN awsome. I sure am glad all you guys are spending these cold winter months tuning. care to share some tuning strategy with the rest of us? are you running water injection by chance? what fuel were you using?

real real good job man!

so how much dyno time do you have in trying to get there?

ZeroBanger

What are your mods? You have identical a/f as me, I dynoed at 315.8 @ 12 psi.

Thanks

I have an 88 TII. I was just wondering what numbers I could get with stock turbo, and maybe a street port. I guess 14psi would be a reasonable amount. Full exhaust and TID of course. Thanks

Craig
88 TII 80k miles no mods yet

dmotoguy

now all you need is some turbos that can flow

thedguy

What mods (i.e. exhaust...) are you running besides the EMS?

holy ****!!!!!!!!!!!!!

Bigreddawg

Do you by any chance have the SAE corrected numbers?

killa7lb

have you taken it to the track yet....the number posted was before you made that hp? i have a friend who made like little over 350hp with stock twins...he ran 11.2, his internals was not stock....so i guess you're a mile ahead of the pack if you should port your motor and bigger turbo...correct.

Boostn7

the 11.56/11.59 @ 122mph were made with 1.08kg/cm2 on PowerFC *or* 16.5psi on boost gauge.
The car is now tuned to 17.5-18psi on pump gas and I'm just waiting for nice weather to attempt few passes on MT ET streets before getting kicked out from the track(no cage)
Nothing impossible....few been there before.

Looks like you're running parallel. What are the other ingredients of your secret sauce?

no doubt the car made that actual HP, but what was the corrected HP. more or less interested since with the cold dense air in winter, your car will make more HP (actual) but be less in summer, the corrected values would help everyone see what it would make at dynojet known parameters (60 F, humidity, altitude, etc).

Tim

Boostn7

Yes Tim...those are actual hp numbers...
Did not touch computer settings on dynojet and ran it as it was setup.

The dyno was indoors with heat on......so I did not get the full advantage of the winter cold dense air.

FYI: intake temps varied from 35-40 Celcius.

But if you wanna see 400+rwh corrected numbers I will deliver them as well
