Ty Tech Performance built us a rhs 461 that did 886 at the flywheel. Its built for a large shot of nitrous.

 

Made 546rwhp with my 418ci motor yesterday. That is through a big stalled auto.

Add this one to the list.
LSX 454 on a dyno jet, TH400, 706 RWHP


Thanks

 

I hope it is sticky thread

 

Not sure if I can jump on the list or not, but I made 470whp out of a 346.

That is equal to 1.358hp/cubic inch. Numbers should be even higher when I put a FAST on this thing.

EDIT: Here is the video

 

^^^nice car with some very nice numbers....to me navy blue metallic is the best paint on a fourth gen, let alone an SS

 

Thanks man! I spent a while looking for an NBM/T-56 LS1 car. Ended up getting a really good deal on that car too actually!

 

My car made 473 rwhp and 407 rwtq with stock bottom end,a set of ported and decked 241 heads from ARE ,ported FAST 90 by Tony Mamo,Kooks stepped headers,EWP, 240/246. 608/613 cam, M6 with 12 bolt and 4.30 gears and steel Denny's driveshaft.Might not be enough to make the list but I figured I would throw it out there. I think most that have made more have a stock rear or aftermarket heads or both.

 

C6Z here. Made 619whp through a stock 427 short block. 1.45whp per ci.
