new build thread!... forged ls3, rpm 4l80, single 88mm turbo under hood!
old build.... 10.9 @ 126 with 20s on the front.. livernois 2 r cam, ls7 lifters, dual valve springs, sam thompson ported cylinder heads, rick crawford intake manifold, spectre CAI, ls7 maf, Dynatech headers, No cats, X-pipe, FAP tune, magnaflow muffs, yank ss3600, 275 40 17 hoosier drs
That turbo manifold is some art... Great work man.
nice job!

+1 on this. some nice cuts and welds in there! what is that a 4" exhaust?Originally Posted by wastedrubber

Yes 4" exhaust all the way to the rear axle then split to dual 3" for 2 ultra quiet resonators. The wastegate is also recirculated into the down pipe

You just want to keep the long side hot.
Rest in Peace Charlie!

Just a GT
Well there a lot more to it. It depends on the turbo. If it's a twin scroll then it's ideal to have equal length but it's not necessary as the effect will only be caused when a big difference in exhaust flow is caused. So it may be Un even for a little bit. The turbo will spin the same anyway because it on the same shaft. Also if it's a single wastegate then the pressure will even out between the "up pipes". With Duel wastegates it would not. But the unbalance in manifold pressure can cause the cylinders to ask different from one bank to the other. Again all the cylinders are connected s it's not a big problem.
A single scroll it don't matter and like ray said just keep it hot.
These are little causes to loose efficiency. Not a big deal unless your trying to squeeze out every last bit.

Subbed for results, can't wait to see it. It's going to be a beast for sure.

I'm still interested in seeing what you used to relocate the ac pump.

well i have now decided to take this build to the next level, bought a forged ls3 short block, and throwing in a rpm stage v 4l80 with 4000 precision stall.
