What would I need to increase HP in my LT - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

dangnplus · 04-07-2013, 02:09 AM

Right now I'm sitting at 323 HP, what all do I need to get for my car to sit at 350+ ? without turbo and supercharge!

I have a 2lt, and apparently a good CAI will get you 10ish hp, and maybe a tune of you dont care abut warrantee. I always said no to turbo/forced induction till' i drove my buddies 1lt with a sts single turbo, the thing is amazing, and he installed it all himself in one night. just over $5000.00 canadian. as for 350 plus hp, maybe cai, ported tb, and exhaust might do the trick. corsa is the way to go for v6 camaro.

Port and polished heads and a cam can bring your power up 40 to 80 hp roughly.

If you don't want to dig into the engine internals, you're looking at CAI, ported throttle body, high flow cats (no other exhaust mod--outside of headers, which if you have a 2013 you can't do--will add HP), and a tune to increase HP.

CAI, full exhaust set up are the best to start with. The ported TB sounds like a pretty good idea as does a tune. Those should get you to where you want to be at 350HP if not a tad more.

he has a V6 so it would be 4 cams, not one.

It's a cam in a can. Not an actual cam swap, but that's all I know about it.

OP, adding 27 HP at the crank shouldn't be hard at all. Get a CAI and a full exhaust then tune it.

skibik · 04-07-2013, 10:59 AM

I add an Injen CAI short ram and that was a claimed up to 15 HP. I just recently added Solo high flow cats and was told by Solo they will add 15 RWHP. I added the ported TB before the Solo HFC's and I didn't notice much gain. There is a dyno sheet on a before and after in the LFX section that does show over 9 RWHP on the ported TB change. It does have more mid range response I thought. I have also seen dyno sheets on the before/after tunes and it looks like you can pull another 10 to 15 HP but I have not gone this route yet and I like to know i have warranty on my car. From my understanding a tune will void it. So the conclusion is the CAI, the HFC's, and the TB add approximately 39 HP now add that to the 323 HP I should be around the 362 HP mark.
