    Dumb question

    While replacing my valve cover gaskets on my 07 gp gt, I had to take off a bracket that has 2 pressure sensors on it. One was plugged in to the vacuum line that goes into the LIM (I believe, as it's just under the snout of the SC). The other pressure sensor didn't have anything hooked up to it...

    07 GP GT: Sudden loss of horsepower?

    I just got home 5 mins ago, took some time looking my car over just to see if I could find something. The problem occurred while at a stop sign, I slowly accelerated like I always do in town and about 20 ft after the stop sign I heard a soft pop and all my acceleration just died. At first I...

    2007 Grand Prix GT Lower Control Arm Size?

    Looking to buy new control arms for both sides of my car but I'm not really sure what the whole 20mm, 24mm, etc is on the options for new ones. I assume I should ask before I buy a part that doesn't fit my car correctly.

    Loud supercharger whine at high rpm?

    Took my 07 gt put for a drive and noticed at full acceleration with the boost gauge maxed there is a fairly loud whine coming from the supercharger I think. It wasn't there before so I'm wondering if I need to replace my supercharger now. Any insight would be great guys. Sent from my HTC One_M8...

    Bearings on my cv??

    So I'm taking my passenger side cv shaft off today, pull it out and see some bearings on top of it. Anyone have any idea where they could have come from? Also, one of the teeth on the cv is sheared, should I be worried? Sent from my HTC One_M8 using Tapatalk

    Driving issues

    So, I've come across 2 new problems on my 07 gp. The first is when I put the car in reverse it sounds like the right wheel pops. I have no idea why it does that. Second thing is I just got in my car to drive home and put it in drive, hit the gas, it made a gear grinding sound and the tcs came...

    Fuel pressure check

    I'm getting some slight indication that my fuel pressure is dropping, such as a dead space in the pedal before the engine actually kicks in and starts to accelerate, mild sounds like it's being starved of fuel, gas mileage dropping slightly, etc. I've got the tools to check my fuel pressure...

    Horrible coolant leak

    I've noticed a leak that's been slowly getting worse on my car. I replaced the lower radiator hose hoping that would fix it as I thought it was leaking from there, that made it worse, so yesterday I replaced the water pump and gasket. Now its literally pouring out of the front of my engine. I...

    Engine rebuild info request

    So, I'm looking to buy a second engine to rebuild and drop in my 07 grand prix. When talking to a machine shop, what should I ask question wise to see if they're good, and what options should I ask them to perform on the block to get it ready to build? Thanks for the help guys.

    2007 pontiac grand prix gt axles

    Any suggestions on axles that will handle up to 500 hp? The only review on the zzp stage 2 axles is fairly negative and the poster says he's only running 250 whp. I've tried searching online but I've came up with nothing so far.

    Htv 1900 or 2300?

    Anyone have experience installing one of these superchargers? I knit won't be easy and I'll have to mod a ton of other parts to compensate for the horsepower increase, but I'd still like to give it a go on a secondary donor engine. Thanks for the input guys.

    Exhaust rattle?

    I have a weird rattle that I believe to be exhaust related but it sounds like it's coming from the engine compartment, any suggestions as to what it could be? It only rattles when I accelerate tho. Thanks for the help guys.

    Pulley drop question

    I'm not going to do it tomorrow or next week, but I am planning on doing a pulley drop after molding my car in the future. I'm curious as to what the life expectancy of a car is after the drop, I imagine not great but still I'd like guys that have done it to tell me their experience. My car is...

    Ignition tune

    Looking to replace my plugs and wires, I've been told autolites are the brand to get, however I wasn't told which specific model to get, any suggestions? Also, which wires perform the best in the gt SC? Looking to drop pulley size in the near future too.

    07 grand prix gt headlights

    So, just got this car and didn't drive it in the dark since the dealer isn't open after 4 but I noticed on my way home tonight that the regular headlights don't work. I have high beams and fog beams but not the regular set. Any idea on where I should start? Thanks for the help guys.
