How much RWHP

Just dropped car off at Cincy Speed. Having LG G6X3 cam kit, LG Underdrive pulley, electric cutouts, and a Hurst Short Throw shifter installed. Already have ARH 1 7/8 headers, X-Pipe, 3' catless exhaust, and ADM Racing CAI. After all installs what is your guess on hp #'s? I'm hoping around 490. They'll have it done on the 11th. Will post vid and results.

Wow. Rick has his hopes set high. We will do what we can but on our dyno, I dont know, maybe 490. I can see a possible 470-480whp, as we have seen that many times. A Fast 102 may help get you there with a NW 102mm TB but I guess we will have to find out.

BTW that N2O Kit will definitely put you ...a little...beyond your goal.

450 is my guess. I had to have heads ported to get 470.

Whatever you do please do not wast your money on a FAST intake and NW TB! I bolted one on for a 0 gain! I have everything you do and more.

I'll probally get this done the 2nd week of Feb. If not the NO2 kit I'll have the SC on by the spring. I know we'll probally get around 470 from everything I read, but we might get surprised.

Mine made 495 hp/469 tq to the wheels with the stock heads, looking to make around 530 now on motor with heads. It made 702/785 on a 200 shot.

6 speed/Ls3

We consistently see the 470-480 whp with the G5X3 cams with no heads in these cars. This is thru good exhaust also not cutouts or anything. Our dyno is very conservative it seems. We have had many of our cars produce larger numbers at dyno days and such but again numbers are just that and dynos are a tuning tool.

475-490 Porting the stock intake manifold is worth 6-10. Definitely worth while if the car is apart.
