That is not true, not by a long shot. You cant take even a modded LS to the HP levels of a Terminator. I know of several that prove this. One dude has an 04 making 727rwhp, his only mods are a Whipple (the small one), cat back (still has all 4 cats), 80lb injectors, CAI and a tune! Thats it! A LS would have popped long before that. Another friend with an 04 was making 699 rwhp on a complete stock setup with the same Whipple! Hell, both those cars made 590rwhp with the Eatons still on them. Npw the one that was making 699 rwhp has an Aluminator block in it. Same internals as a Termi but with a lighter block and higher comp pistons. At 10psi hes making 640rwhp. Now he is upping the boost to 18psi and will see well over 800 rwhp. Kevin is upping his complete stock setup to 24psi and he will see over 800 rwhp as well.I love Cobra's...but seriously throw a Twin Screw Supercharger on a 98-2002 LS1 Camaro and say goodnight lol.
A stock or even built LS1 cant make that kind of power.
In that same club there is an 03 Sonic Blue with a TT conversion and better pistons, full exhaust and thats all his mods. Hes making 1197 rwhp and over 1000 rwtq.
The LS is a good motor but the forged internal 4V motors are better.
