Best path to 400rwhp L99 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Aaron0731 · 03-02-2017, 04:51 PM

I have a 2010 SS I've owned now for a couple years and still love it! I've never ran my car on a dyno but will be doing so soon... So I don't really know what it makes now but I believe it's very strong...

Ok so my current mods are JBA high flow cat connections pipes, magnaflow cat back, spectre cold air intake, and a wonderful tune from dynosteve.

If I just add longtubes would I be at 400rwhp? If not what should I get?

JWade · 03-02-2017, 05:12 PM

You will be close. Full exhaust, cai and a tune got me right at 390 rwhp.

Bo White · 03-02-2017, 05:30 PM

Yes full bolt ons will be very close to 400rwhp depending on dyno.

pyroguy · 03-02-2017, 06:04 PM

Being a 2010, you lose a few hp freed up by the electric steering. I have a '10 L99 like you and I have a rotofab intake, Bo White TB, long tube headers and a catback exhaust and post tune I made 365rwhp. Most of L99's just bolt ons, you're looking at about 375rwhp max with a few exceptions, but not 400. You'll have to dig a little deeper to get there by adding power adders, cam, or go way over the 400 mark with forced induction.

Mild cam!

Don't get hung up on the number. How it runs on the street and or track is all that matters.

Enjoy the broader power under the curve of the vvt

If there wasn't something to that... the top of the fast list wouldn't be littered with l99s

Ditch the afm and you will be thrilled.

Bolt ons and e85. Stock fuel system will handle it at that power level.
