Mark's LS2 2nd Gen Camaro build by Marktainium

4 minute(s) of a 242 minute read

All back in and running. Still sounds like a DURAMAX. I've given up on the noise and am accepting it as NORMAL. (if I win the lottery I will build a new motor, again.)
Here's some pics...note the koolcoat on the exhaust manifolds...going to wrap the turbo's and the pipes to the manifolds...

here's the car at aircare...(smog testing)...secret to pass? no charge pipes, stock tune, small injectors, testing for 1971 standards...result? CRAZY LOW NUMBERS = PASS

The one below is a video

Here's the last piece of the plumbing puzzle...top merge pipe from intercoolers to manifold.

Thanks guys!

A bit more done tonight, I made a new fan shroud out of aluminum. Pretty straight forward, had to do a few notches for plumbing and the BOV.

Installed the intake merge pipe and BOV properly for the first time. Fits good. I painted it black but may go back to brushed finish.

Working on the tuning now, spent 3 hours creating a 2.5 bar VE table this morning. Running now.

Increased the boost from 6 pounds to 9 pounds. I don't think I'm gonna need to go to 21 psi. 9 psi, 3rd gear, 2500rpm, mash the gas, you are in the seat hard, front end is getting light, left front corner is twisting up, tires are scrambling for traction... I think my goal of breaking the tires loose at highway speed is going to come sooner than later...

OK, you asked for it... Told my wife we were going out to get some ice cream after dinner... Funny, I could have sworn there was an ice cream shop somewhere in this industrial park ?!??

DYNO NUMBERS...

Mustang Dyno, 15 psi boost, pump gas (chevron 94), very conservative A/R and Timing for road racing.....

622 RWHP 630 RWLBFT torque.

I ran out of time and money on the dyno to go any further. The tuner figured that on any other dyno it would be in the 700's. We had to spray the tires at one point because the power hit so hard it was breaking the tires loose.

In a couple of weeks I hope to return and turn the boost up a bit more. On a side note, with 1 degree more of ignition advance I was seeing 10 extra HP, but it would have an occasional knock. The curve was insane, full torque by 4200rpm, and it felt like there was a second torque curve from there to redline. (my tuners words)
