Well havent driven the car since last June, (see the Mice post in here about the storage incident) and just got it out yesterday with the stock fmu disk and stock a32 and 240cc, with the 2.87 pulley. Well I build boost at about 2500 and have a full 9psi (intercooled) at redline, only did one drive cause I worried of being lean.

Anyways it pulls really hard and feels great. However i need sopme feed back on a stumble I have. When say I am sitting at a light and I rev it to say 4 and just let off to hear the bov the car ussually stumbles to about 250-300 rpm and once in a while it will die! I checked all the vaccuum and found one bad and replaced it. Ithought I had it but the car is still doing the stumble even when coming up to a light and braking it does it. I am at a lost?????? \


Any ideas????

Keep in mind it did this a couple times last year with 3.33 (intercooled)?????
just figured it was a hiccup.

may be grounding. mine did that with a relocated battery and when i added some extra grounds in the trunk and some in the engine bay, it idled better.

Wow, you sure are loosing a lot of boost through the intercooler. Only 9psi with 2.87 pulley. I would think 12-13psi intercooled would be normal since 2.87 pulley gives 14 psi.

I'll try that!-thanx

yea right at the blower I have a 90 degree to the drivers side and the a 90 degree down and then a 180 up and then a 90 degree into the intercooler. I am going to remove the windshield squirter reservoir and relocate it and then redo my piping I will be able to illiminate three 90's that way. Ibet that will add about 1-2 psi
