Your THoughts

Ok so here is the deal. Yesterday I pulled my exhaust off at the end of the Down Pipe. I was driving it around today and noticed that in 1st and 2nd my boost was hitting all the way to the top of the factory 14psi boost guage. This is the only mod I have done to my car. I didnt hear any detonation. What do you guys/gals think that I should do? Should I worry about it? Should I hook it back up? How high do you think it could be getting?

could be spiking pretty high with only you DP, that's a lit more exhaust flow.. I'd get a boost gauge and see what you're doing there.. I suppose if you're not hitting fuel cut it can't be too bad.. but boost gauge is a must before you start modifying anything...

That doesn't seem to normal to me, but I wounldn't worry about it to much just yet. I would get a boost gauge and see just how high you are boosting. What has me a little confused is that normally without any other mods like a boost controler, you can normaly only get a few extra psi out of something as simple as that and this sounds like a lot. Keep looking for other changes in the way she drives. Noises, surging, stuff like that. Keep us posted on what happens.

Sounds like creep. When you remove the exhaust, the restriction goes away with it, and your turbine can "breathe" much more easily. On some turbos, they can't divert enough exhaust gas through the WG and around the turbine so the turbine drives the compressor more than you want, and your boost creeps up until the increased restriction in the turbine housing and increasing backpressure in the ex. mani. eventually lets the WG "catch up".

If you disconnect the arm on the WGA from the lever on the turbine housing (may be different on your 1g) and first check that the lever turns freely with your fingers, then go for a full-throttle run, you shouldn't boost more than a few psi. If the boost goes much higher than that, it may be creep.

Removing exhaust restriction (putting on a test pipe or going to a larger, more free-flowing exhaust) often leads to creep problems. If that's all you changed and everything was fine before, I'd bet a nickle on it.

Give it a whirl and let us know.

You should stop dicking around until you have installed a real boost gauge. The factory gauge is only interpolating, it's not measuring.

And please use descriptive thread titles in the future.
