if you were going to use a vacuum pump would it be moroso or aerospace?

i see the aerospace is 750.00 for the kit and the moroso is 900.00 or so. what are the pros and cons with these 2 pumps?

What is YOUR purpose for it? From what i've been told on a BBF deal ,the only reason I would use one is if I were running Alcohol for the moisture purposes.jmo

If you're looking for the best pump, I would go with a Star. If you're looking at those 2 laying on your shop table, then I would go with the Moroso.

I'm currently running aerospace three vane pump, and my Buddie has the Moroso 4 vane pump on his motor. His at 2000 rpm's pulls 15 # vacume mine at 2000 rpm's pulls 10# of vacume.

I don't have any experience with the Aerospace pump, but my 4-vane Moroso has been trouble free for over 3...maybe 4 years. I think that I am spinning it at 65% crank speed too.

i am spraying nos and it blowing the intake gasket out i have replaced them with gasket maker with a big bead and it still does it and i was told if i had a vacuum pump it would solve my problem.

Sounds like you need some help for sure Are you running Evac tubes to the headers now

its called detanating, your tune is off, if its right it wont do that, a vac pump will gain you power, it has on every engine we have tested, anyone tryin to make all they can should have one,even on a dry sump they help

Moroso. I used the 4 vane which is a dry sump setup on my wet sump engine. Just limit the vacuum with a bleed off valve to where you would like to run it which in my case was around 12 inches. The Aerospace won't pull that kind of vacuum even if you run it 1 to 1. There is more to just bolting a vacuum pump on and running it. Low tension rings, engine sealed real good , vacuum gauge to monitor the high rpm pulls, etc. Watch the bearings also, too much vacuum can and will wipe them out. There is power to be made but you have to work with it.

I had a Moroso on a car before and currently am running an Aerospace. On my motor it CAN pull 18-20psi but I have it limited to 12. I'm not sure on you bb guys if it would be able to do that though.

I think I would go with a GZ Motorsports pump or the Moroso.

are they a tool to check the vacuum with if so where can i get it and part#

You can usually get a vacuum gauge about any auto parts store.

I would use the Moroso. The best on the market in my opinion is the Star.
