Thumbs up My new 0-155 MPH speed run!

Just did a speed test run and uploaded it tonight. For all of you who assumed I really was making 298 WHP, I'm pretty sure the acceleration don't get like this in a full weight ISF chasis

Power Mods:

RR-RACING ECU tune
Deleted ALL CATS
Custom full 2.5 inch x pipe to borla mufflers

Other mods:

RR-RACING AOS (Air oil separator)
RR-RACING USRS ( Ultimate steering response system)

Going to do a re-dyno later on this coming month or so.

Hope you guys enjoy!

nice run. if you ever have your F on a lift, i want to check out your custom exhaust. i'm going to design my own cutback, well just the mufflers/tips with magna flow mufflers and i'm looking for ideas. i just need to find the right shop as i haven't had exhaust work in a few years. probably will be the last thing i do to the F this year though.

Did you get your redline raised? Seems like some perfect shifting at 7k without any cutoff.

That is looking really quick. By deleted cats I'm assuming your running the stock manifolds with the main cats chopped off.

Looks like we all need to detune our ISF's to 300whp, no traction issues, pure acceleration!

Car looks to reach 150mph in about 22 seconds, a great improvement from stock which I think is right around 25 seconds. C&D got 24.7.

This kind of documentation is actually way better than a dyno IMHO. If you use the same stretch of road and use a watch or timing device to record the internals in 1000 rpm increments, you can measure real improvement. If you normalize with density altitude corrections, you have the best possible measure of how the car performs in the real world with full airflow, hood down, and everything delivering as expected.

That's exactly what I thought when I paused it @22 seconds he was right at 150mph, like you said another publication got 25 seconds @150 mph for the F and the E92 M3 was 24.9 @ 150mph.......so to reach that in 22 seconds that's a major improvement in top end acceleration!

I agree with you I'm starting to loose faith in the Dyno numbers that have been posted including mine which showed no improvement with my Borla exhaust and basically the same numbers as my stock dyno run

wow, even more impressive when you consider he didn't even start until 1 - 1.5 secs on the video timer.
