Default 228/232 Custom Grind Ls1

Just got my car back from tuning. This is the same cam Slowhawk was running in his 11.50 bracket F-body.


My stock numbers were 337whp and 343wtq with IATS around ambient

Well after bringing the intake back into the engine bay after a close call with a puddle last year IATS this time around were supposedly around 150 degrees And he said hes seen large losses in torque when using the sweet thunder resonators because they neck down internally. Gonna hack them out and run straight pipes. I will also move the intake back to where its getting fresh air.

Planning on changing those 2 things soon and I hope to get some power back, esepecially torque.. the torque has really got me scratching my head.

After Cam numbers 383whp / 351wtq



Given the conditions I know its low and I hope to gain most of it back when I make those changes, hopefully without another tune, but what do you guys think?

Sweet thunder and dynomax bullets as resonators.

What are the rest of the specs on the cam? Lobe profile? LSA? ICL?

BTW, shrink down your image.

I have the same Cam in mine and made 402/378 on the same Dyno.

I have:

longtubes
ORY
catback with cutout
underdrive pulley
lid and stock ls1 intake.

This cam is definitely bad ***. Sounds like you just need to work some bugs out of your car.
