That car is revving up way too slowly, maybe stuck ports or clogged cats or something, it should be way faster than that, mine is anyways.

Give him a break about the temp gauge, its normal, its fine, thats how it is no matter what you tell him to change or fix, thats how it will sit no matter what.

But yea, the speed is seriously lacking, i'd look in to some of the high end power robbers and see which is your problem.

If you wanna avoid more of these S4 guys and such you can PM me, I can make a video of mine in 1st and 2nd to show you how big of a difference there is.

 

I am basing the 483 FLYWHEEL number off my old 410 wheel dyno. According to my calculations, with a 15% drivetrain loss 410 rwhp should net you 483 at the engine, which is what I made on C16 and 15 psi. Of course I want to go around bragging with the highest possible number so I took the high boost flywheel #......
LOL

483 X .15 = 72.45 <-----drivetrain loss

483 - 72.45 = 410. 55 <----- rear wheel horse

Of course I would have to re-dyno to verify my builder's numbers to please the guys down here, but he does have a reputation for giving out conservative numbers. Sounds about right since a lot of guys with T78s make closer to 420 on 15 psi even on pump gas..........

BTW I made 330 on 10 and 370 on 13 psi which is of course 390 and 435 horsepower

 

Ok

 

Hey man, if you can get a vid of it and send it to dcytsang@gmail.com
it would be great! Thx.

 

Dyno'ed my car at 143rwhp in a 70% humidity day. Around 30C and 400ft above sea level.

Anyone can give a corrected hp reading?

 

My car is the same way. Its not overheating though... Anyone in houston mind taking a look at it?
