Simple set-up, stock sleeves and big power. Owner is coming back with larger wastegate, spring and more fuel system upgrades for more power.

Those are some nice numbers for a simple setup.

[eg6jdmhatch]

wow..really nice numbers..i have a similar setup so hopefully i can see those numbers as well..

[loub18c]

nice digits,enjoy that power

[T4 EF]

why was the upgrade of the wastegate necessary? was the 38mm not able to hold the boost?

[boosted hybrid]

Wastegate is far to small to hold a small spring.

[T4 EF]

sorry... so did he change the wastegate itself? or just the spring?

edit: the reason i ask is because i would like to know how large a turbo the 38mm gate will take, using lower boost in the 1st few gears and higher boost 3rd or 4th, using something like a dual stage boost controller, ie.. the turbosmart ones.

[boosted hybrid]

No, he didnt. The wastegate is going to be changed along with some other items before another retune.

I prefer dual wastegates on a manifold, or a super large single wastegate with a large a/r and turbine wheel size. Its the only way to hold low boost with a large turbo.

Good stuff Jeff. Little bit of lag but nothing major

[untaintedz]

on your bottom end do you use a girdle i know ls blocks arent made like a b18c or b16 ?
also very nice numbers i hope i can get my car doing those someday.

[AllmotorB18c]

sick numbers for just a simple set up...nice job again Jeff

[g2turbo]

This is why I sold my 38mm tial and bought a 48mm turbosmart gate. Jeff wouldn't a larger a/r on the turbine housing had an adverse effect on efficiency of the wastegate? More backpressure with a smaller a/r causing the exhaust to evacuate from the wastegate easier? Just a thought Im not too sure.

Also do you notice any power or flow differences on cars with precision 600 versus the precision 750 intercooler?

Nice Work!

[speedy108]

Was the Tial wastegate having problems holding that much power?

[v8killr]

Was the Tial wastegate having problems holding that much power?

SOULDNT HAVE...ILL BE RUNNING A GT42R AND A SINGLE 44MM TIAL WG...LOL!

[boosted hybrid]

Yes, it was. It was creeping a couple pounds at low boost.
