Of little to no boost response.
I've recently re-installed my twin set-up with a few "tweeks" here and there for ease of maintenance and reliabilty. I have an absolutely leak free set-up on both the cold and hot piping sides.
When I previously had the set up installed, it totally incenerated the tires the tires from a 35 mph roll. Now for some reason, not known to me as of yet, it will not make much if any boost. I'm pretty sure it's not the motor itself, the #2 hole was a little lower then I'd like. But I don't see how that would effect boost response so drastically. Especially in a twin set up using the little .48 A/R turbos I have. I bet 2 1/2 cylinders could get these things spinning pretty quickly. Speaking of spooling, I have the exhaust from the turbos just dumping right at the bell houising on either side. I can hear the "whistle" as the turbos spool (You can literally hear the whistle from 1500 rpm) but no boost is registering.
The car will idle just fine but has horrible driving manners. The biggest change to the car as compared to when the set up was last on the car is the re-configuration of the intake. I'm wondering if it could be something as simple as the Throttle Position Sensor as it is the only item the computer uses that has been moved/altered. It's now upside down.
Basically i'm just looking for ideas/input/thought on areas to check before I yank the motor. Posssible for this to be ignition related? Electrical (mass air, TPS etc.) related? Or maybe even a combination of the 2?
TIA
