Ok so i installed a thunder racing TRak Cam (check my sig for the specs) in my car about two months ago and I'm not real pleased with its performance but I'm pretty convinced that my supporting mods are to blame and not the cam? I have full exhaust with LT's with an ORY but stock heads, stock intake manifold, stock injectors/fuel rails, stock TB. What do I need to replace first to bring out the most potential. Please help cuz its crazy sluggish down low... and well almost everywhere in the power band lol so any suggestions would be appriciated!

Thanks
Kyle

no doubt that ls1 manifold is choking up that cam.. definitely look into an LS6 intake.

^^^^^ + pulley + P & P TB....these mods combined may net another 20hp.
Steeper gears will help too, especially 4.10s

I don't see any mention of a tune in your post or sig. Have you had any tuning done for the cam? Has it always felt sluggish or did it run better at first?

thanks for the input guys! I have invested in gears so hopefully that will help a little and as for the tune i have a mail order tune from pcmforless and it has run this way since i installed the cam. I'll be getting a full dyno tune here in about a week so that should help as well. but it sounds like most of you are leaning towards the intake being the issue? could my stock injectors be causing any problems?

Could be injectors yea, my buddy had his almost maxed out when he had just a hotcam Then when he swapped in a torquer v2 definently had to upgrade injectors. When you get your dyno tune find out what %duty cycle yours are at when WOT and that will tell you if you need to upgrade...

Get a real tune, then see where you stand. Might not be a bad idea to get an LS6 intake on there before your tune date either, but that might not be possible.

i had a "mail order" PCM4less tune, i was less than pleased.. i went back to my original tune and just modified it myself.. look for a cheap set of ls6 heads and intake and you will be alot happier.

Forget the pulley. Gears are a good idea when you go and move the powerband up in RPMs.

cheap way to pick up a few hp.

Tune and intake could be a big help, doubt the injectors are the issue.

You need an intake and a real tune

I dont know about you but I had that cam in my old car the car pulls freakin hard.

Get a real tune and LS6 Intake forget the gears and pulley but your tuner should tell if you need a bigger injectors or not.
