Thread: Dstratt01's modded Gt

What I want to know, is how you're gunna make the trans work once you go above 0" of vacuum.

Ive been doing some research and talking to my professors in my auto classes and its seems that swapping out the vacuum modulator should do the trick to keeping the trans intact. Anyone ever tried this before or is it a waste of time?

Swapping it out for what?

possibly the modulator from the gtp if that would work. need to do more research.

also just installed a triple pillar pod. running a boost/vac right now. ordered a oil pressure pod. not sure on the third pod yet but im leaning towards an autometer D-PIC. anybody with a different suggestion? not looking to shell out $300 or else I would already have the DPIC.

Gtp doesn't have a vacuum modulator

Havent been on here in a while. Also havent touched the grand prix hardly at all. I bought an Eagle Talon Tsi AWD for $500 so thats where my time/ money is going for now. I still havent started the top swap yet but i did install some new gauges. And put the factory wheels back on it for the snow. other than that not much has happened...

The dsm will consume all your money. They are notorious for bring unreliable.

I heard you cant use underdrive pulley's on a supercharged application... Have I heard wrong?

I heard that too.But i have seen a few people run alt/WP underdrive pullies on GTP's with no problem. I couldnt see why you cant though.

You can run underdrive pulleys on the alt water pump ps pump but it's not worth it. The supercharger and the other stuff run on separate belts.

The water pump ud pulley is the only one worth it, it actually frees up 3 hp and 5 tq (atleast on a stock gt). The alt pulley is only if you want to up the amps on your alt and won't free up much hp.

My car dosent seem to run any hotter then before i added the UD WP pulley. It helps with performance a lil bit though.
