Video! Finally got on the dyno, Texas Speed Cam/Headers - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I finally got everything in and tuned, it drives very similar to stock. Low speed parking lot driving is no problem. Power is amazing, it hits very hard and just keeps pulling! As far as fuel economy, I have no idea because I don't monitor it. Just pull up to chevron and pump in the CA cat piss 91

Last sat we spent about an hour on Motor Machine's dyno with Mark Romans, 5-6 pulls later the car put out a non-SAE corrected 449HP. It was still making power all the way up to the rev limiter, but I decided not to raise the limit.

I've also added some house brand 3" electric cutouts and changed the h-pipe for an X. It sounds much better with the x-pipe.

Thank you Marco Muffler in Orangevale for those PERFECT looking welds, excellent finishwork!

Parts List:
TSP 229/236 113LSA, TSP 1 7/8 Headers w/o cats, VaraRam Tune version, H-pipe, Magnaflow round mufflers, Hurst Shifter, 22" Niche wheels.

Haha sounds good. If you are in the area you can go for a ride, this thing pulls like a freight train! The cutouts sure are fun, it sounds amazing at WOT.

I would think that the numbers from that dyno are way low also..... I run the 235/239 cam with 112 lsa and had it dyno sae corrected on a mustang dyno for a lot more than yours with semi similar mods yet with a 2013 and dual mode and electric power steering. I know they are just a tool to measure with... And your smart not to raise the rev limiter as the power does decline that far up and you only risk valve float..... Nice car. You did get your torque management handled in your tune didn't you? And you can tell you had data smoothing on the screen from the dyno, and your AFR is all over the place sort of..? And its hard to interpret that screen, but hey hopefully you had a competent tuner who had a whole library of past LS tunes to adjust the AFR to optimize its power, And yes these TSP cams do pull like a freight train...LOL I imagine you could get a far different number off a different dyno especially if its not a stingy Mustang, or what ever type that was.
Low speed parking lot driving sucks with a clutch.... and idle at 900 and going to around 1500 to avoid cam surge....... Its put it in gear go then take out of gear and coast via clutch pedal, then rev it to 1500...etc etc lol for me..... And traffic jambs suck hard, My clutch leg gets a work out then....

I dont see why you would get valve float if youre reving to 6500. You are going to lose power between your shifts. I'm pretty sure TSP recommend bumping up the redline to 6500-6600 (depending on the LSA and setup). I'd shift at 6400-6500. You are not getting the most out of your combo.

Stock bottom end LS3 are spinning to 7K without problems on stock rockers/good springs with agressive cam grinds.
