Uhhhhh .63 or .82 What?

I've been working on this car off and on since 2006, this will be the first summer home since 2003 :icon_rolleyes:

I have ported the stock exhaust manifolds into "D" shaped ports. I want to port my crossover and get some more flow out of it. Also planning on a 3" downpipe "modified" to fit with the powercrapper III.

I've got 30 & 38 lbs injectors, not sure which Ill use just yet. Got my WB 02 yesterday :icon_mrgreen:

if your buyin a gt30 you have to pick between .63/.82 unless your going 1.06!!!

Yes, I put he auto back in place and found some extra room for a turbo... That's about it...

Quote from: slick94prix on January 21, 2009, 03:24:55 PMAlso, if you have a smaller turbo on one bank, and a larger on another, wouldn't you experience a slight pulsation in the air from the turbos since one would flow xCFM, the other flowing a larger xCFM?

It's all in how you merge them together... Also i am not planning on maxing out both turbos. I just would like a clean 16psi with not much heat involved from the turbos... ;)

Theres always the electric turbos................................sometimes I kill myself :laugh: :laugh:

If GM cramed two turbos on the beretta, then the TGP is a breaze. ;)

killinprixs · January 30, 2009, 10:56:37 AM

dam 385hp on 16 psi on the 3.3.

Just think, the tc's are probably undersized, few restrictions (exhaust, intake etc etc) and that is only at 16 psi.

Put two or one properly sized turbocharger/s on it and 3" exhaust it with a decent charge pipe/intake setup.... ZOOMa Zoom ZOOOM!

how can you read the bigger boost + regulate fuel flow/larger injectors with the existing 2 bar sensor and stock computer? I always run into the wall about here and dream about either methanol injection with the existing 22# injectors or buying an evil alien robot capable of making me a new TGP computer that can handle a 3 bar sensor.

Once you understand and can manipulate the TGP code the sky is the limit. I have run over 20psi on the 2bar code with no issues at all... :icon_biggrin: I also made a 3 bar patch for the TGP code and trust me it was a waste of my time..
