    Chevy Volt PWM fan conversion

    I have all the parts and even upgraded the alternator to 200 amps, added a postive post, but no time to actually fit the fan yet. I also got a chevy volt harness from a dismantler for $35. I want to make it look as oem as possible, so it won't be a rush job. I will update as soon as I get...

    Transmission Builder in California

    Hi Guys, I have an 87 GN with 30k miles on it. Transmission works fine but plan on doing more mods to the engine and putting drag radials on it at the track. My goals are full weight 11.70s because I never want to put a cage in it. I would like to keep as decent of a shift as possible as I...

    Oil in coolant. Lean rougg idle

    I did just get a kit from blackstone. I guess i will pony up and pay for the analysis. It cost more to check for coolant contamination, then just standard test right?

    Oil in coolant. Lean rougg idle

    I have pressure tested it with a manual coolant pressure tester with all the spark plugs out and even looked inside each cylinder for traces of coolant. None. I have left the pressure tester on the car for hours and it doesn't drop pressure.

    Oil in coolant. Lean rougg idle

    Hi everyone, my car is running great under boost I'm running E85 22lbs of boost. 11.0:1 AFR. No knock. Runs super strong. My only problem is I see traces of oil in the coolant overflow bottle( not a lot, just a slight amount on top) and seems to be pushing coolant out of the over flow...
