The gain is only about 5rwhp on a stock car. My H/C gained 14 hp over the LS1! :cheers:

Don't waste your money, on a basically stock C5, you will notice nothing.I would only do it if you were doing heads/cam, headers,etc. :cheers:

No way to say for sure- Some have gotten nothing- others have gotten 6 or 8.

It will help you more down the road if you drop in a cam or something.

From what I've seen on the Forum, the gain, if any, would be unmeasurable on a basically stock engine with light mods (intake/exhaust). Remember that GM claimed only a 5hp increase on the 2001+ LS1 with that manifold, and that was with a different intake train and cam.

I say, do the upgrade, but only after headers, high flow exhaust, and high flow intake. You wil pick up 7-10rwhp, and even more torque. but only about 5 if all else is left stock.

You are going to make between 5-10rwhp & rwtq depending on your current mods.

How much of a difference would it make on a s/c LS1?

It won't do much for a stand alone modifaction, but consider it a building block for future mod's.
Anything you can do to free up the intake and exhaust system will be a help. :D :seeya

I have asked the same question. the answer I get from several respectful tuners is MAYBE 5 hp at most. I have done enough mods and dyno tuned my car that the LS6 intake, lifters and cam would not do much. How ever if I was racing every little bit counts.

Mods done:

larger air intake
90 mm ported & polished TB
TPIS Long tude cermic coated headers
Random Tech High flow cats & X-pipe
GHL bullet Exhuast
computer reprogram for 6650 red line
better torque and HP though out the whole curve.
Transmission cooler
oil cooler and accu-sump

We tuned the car for a bit more torque then HP as the torque will help get out of corners faster vs HP is TOP END speed.
