I'm thinking highest had to be PaulZ. He had a TT with Big Stuff 3 operating system and a straight axle turbo 400 C5. Paul went 8.49? with that car, had to be pushing 1K??

My 346 was probably mid 8's?? But didn't care about dyno numbers.

I like this question. I am going to try and make mine do 700 rwhp.

johncbourg

What injectors did you have, and what Boost?

0Arun@ChampionMotors

95lb injectors, it buried the 20lb boost guage. I was running out of fuel, swapped over to dual pumps instead of the Bosch 044 and went SD.

787rwhp stock bottom 346ci here. 696ft-lbs. 11.5 pounds. 93 pump. 12 degrees of timing. Twin 67mm turbos. 60 pounders. Maxxed out fuel system(out of gas @5800rpm). SuperFlow load bearing chassis dyno.

775rwhp and 655ft-lbs @ 19psi. Forged 347/F1C Procharger. This is thru an A4 and 3:73 gears/Vig 3400 stall. I'm looking to pulley down a bit and go for 800+rwhp.

Borrowed time on a stock bottom.......

Just got mine back after 15 months of hell. Forged 402 custom built, studded all around, Trickflow's ported/polished, eight rib Novi, Fast 92 ported polished intake/TB, ECS Stage II fuel system, Meth. with a stage IV RPM A4, Pro-Charger red BOV, big lift cam with 12 degrees between duration, and an 11" 3400 Yank Nitro's converter. Made 700 rwhp @ 5500 and ran out of fuel with 60# Motron injectors running @ 14/1 AFR (by design for break-in). Saving for the 80#'s Siemons.

I was planning on racing this summer but with all the b/s I have had I'm just going to enjoy the car for a while. I can't afford anything more to break on the car or break my marriage.

Anyone that leans on the car with a stock bottom end with boost is just buying time (as long if one dosen't get greedy). The engine was not design for that.

14.5 AFR for break-in?

Corvette-Chris

I'll be pushing mine to 800+ soon

Those damn turbos are so efficient...lol. I'm doing 713rwhp on the stock bottom with a t-trim, but it takes 18 degrees of timing. I wouldn't dare try near 800 on the stock bottom end.

Please.

Just because you had a tune issue or a driver mishap and blew your car up....doesn't mean it's going to happen to me. Yes,..I know,...."550rwhp" is the magic internet safe standard rating. Not here. The motor HAS been removed,...and is currently in another daily driven vehicle. Motor is fine.

Smoove

Things are badass man. Truly efficent.

My guess would be 750-800rwhp.
