JD we were talking about the nitrous, and its becoming a possibility. Were gonna start small though and see how the bottom end takes it. I think a 50 shot will do a lot for it.

I think the car has more in it the way it sits.

can I ask how much loot you have in the car/build?

92CXyD · « **Reply #41 on:** March 16, 2009, 09:13:00 AM »

did you do any milling of the block, porting oil pump, matching oil lube holes of the bearings w/ block, or any other tricks? ;D

Do you have any pictures of cyl. porting and intake porting? ;D

Is your car still streetable setup or strickly track? ;D

dvst8r · « **Reply #42 on:** March 16, 2009, 09:56:01 AM »

What about another 10psi instead of the 50shot, that holset still has more in it.

98redcavz24 · « **Reply #43 on:** March 16, 2009, 10:04:12 AM »

Just awesome. The definition of rhmt

Dr. D-Series · « **Reply #44 on:** March 16, 2009, 10:54:28 AM »

Block is not decked. Head is milled a touch just for straightness. Oil pump is ported and shimmed. Running straight 30w heavy duty diesel/gas oil.

The turbo will not support another 10 psi. Its losing boost at high rpm as it is. I think it has something to do with the rpm were running. We were shifting around 8900.

Build cost is really unknown at this point. Its gone through a bunch of changes that have all improved the setup. But its not an expensive build. The cam is the most expensive part really.

When you ported your head and intake did you do just a port match job or did you use a flowbench?

Am I reading that correctly no LSD?

chris · « **Reply #49 on:** March 16, 2009, 01:26:41 PM »

I did the intake manifold. I have worked on flowbenchs enough I know what works and what doesnt. Proof in the pudding is it works.

Flowbench time is very expensive unless you personally own (10K)+ name brand units. When your porting manifolds for under 100 dollars to compete with CDM intake manifold like Bloxs sohc manifold that are horrible designs I have to undercut their prices. Also once you have worked/found out what works on a flowbench you dont have to keep retesting your work. Port work is an art form your hand will be pretty damn accurate after 100+ manifolds/heads.

How much to port y8 head and z6 mani and through on a 70mm TB w/ spacer? ;D

A 50 shot will get you 75+ to the wheels, it really depends on how free flowing your hotside is.

I think that it might be a wastegate issue, as in drive pressure opening your wastegate. I have run that turbo over 40psi and not had it fall below 40psi @4000rpm in a 5.9L motor or ~23600lpm vs your 1.6 @ 8900rpm ~14240lpm. The drive pressure on that turbo @ ~40psi in my experience has been (with a log mani and the 18.5cm housing) about 50 - 52psi or about 1:1.2 which is imho pretty safe, drive pressure to manifold pressure.

what spring is in the wastegate?

Dr. D-Series · « **Reply #58 on:** March 16, 2009, 05:21:40 PM »

Found one why its been losing boost. It was doing this on the dyno too.

Exhaust gasket on #1 runner was totally GONE and the 1 of the 2 bolts on the WG was falling out. BIG leaks. Ill have it all taken care of by the next track day. Im also getting my exhaust manifold flange milled since its pretty warped.

The 2 springs in the WG equal 20-21 psi. The boost controller is only adding about 4 psi.

Head was ported and I didnt follow any guides other than what my finger felt going through the ports. Took out whatever didnt feel right to me. Nothing special, but it seems to be working fine.

The turbo now SHOULD support more boost with the exhaust leaks fixed. Maybe we'll throw a couple more psi into the motor.

dvst8r - Thanks for the info, now im confident I was having issues only because of the leaks.

I think just a 50 shot will get the car near 10.0 to 10.1. We'll see.

Joseph Davis · « **Reply #59 on:** March 16, 2009, 05:29:57 PM »

Nitrous will hit somewhat hard and can cause traction problems, try for boost first.
