Vacuum pump for ls1 fbody anyone? As I'm wrapping up my bolt ons I'm going to try a vacuum pump. It's not a waste of money for me as I'm building a radical 402 llsr. So why not try a vacuum pump now?
Does anyone one have experience with one?
Has anyone tried the GZ motorsports kit?

I have a couple pics. I'll find. Yes, fairly easy to install. One thing you find out is that the pump will not fit with the A/C accumulator in the stock position. You have to remove the bracket, from the accumulator, so it can be moved to clear the vacuum pump. It's a pretty tight fit with A/C. Ended up fabbing a bracket for the accumulator to hold it.
If you even have A/C lol.

No problem. Never did a back to back on the dyno. I could definitely feel a difference. The first things I noticed were the engine actually ran better. Noticing at lower rpms it helped with the little bucking I got. Makes the engine feel a bit smoother. I seriously don't want an engine without crankcase vacuum. Definitely worth it to me.

Well. I'm not daily driving the car anymore. But I use it regularly. Off the top of my head I think the pump has been on for 2 years. Maybe 15k miles. Zero problems. If I start to see a difference in vacuum the pump can make. I'll just send it in for a rebuild. Last I checked $75 for rebuild & test.

I showed them my set up so they worked with me and sent something that should work with what I have. I have not had time for the car and just had to put a rack in it. I will try install soon. I think they are worth a tenth and MPH on most cars.

Be cool to meet up again. Pretty sure I'll be going to No Guts No Glory in December.
