Vacumm Pump
 

I want to put a vacumm pump on my dragster this year. Does anyone have an opinion on which brand to use? I have been looking at kits from Moroso and Aerospace.

I second that Star Machine has an excellent product at a reasonable price. Stay away from Aerospace stuff.

I love my Moroso three vane pump. And they stand behind them.

Five seasons on a Moroso pump for me with no problems what so ever. .......The Star pump is a pretty trick piece too, but I've seen at least three of them have the vanes come apart. .....I'm sure this can happen to a Moroso too,but I haven't seen it. .....Tom

Anthony,

I just took a Star Machine set up of my Top Dragster. Worked fine but my new engine came with something else so i am selling this set up. It is the standard vacum pump from Star as well as the mandrel and the intake and exhaust tank with the #12 ends. Cost new $1100.00 will sell for $800.00. Havent advertised yet. Kind of pricey but they work well. Let me know.

Thanks.

A friend had one.....it pulled very little vacuum. He was told to add a little oil every day he raced it. It still never worked very well and after he pulled it apart he found it was worn inside pretty badly. This friend doesn't race very often these days so the pump had very little use. He sent it back to Aerospace and got no help from them. He bought a Moroso and it works fine. I had a Moroso 3 vane for 3 seasons on my injected dragster. Sold the engine and the pump with it and it went 2 more seasons and was still working fine. The 3 vane Moroso pumps had a reputation for breaking either the set screws or the shafts. I took my Moroso apart regularly looking at those items but never had a problem and the pump worked very well for me.

Star pump= great product, great service,and also does maintenance (yearly)
You won't believe have much cleaner your motor stays!
Plus he is local and does all the pumps for the top half of prostock.

Re: Vacumm Pump
 

I had a Aerospace one that worked like *%^$ it locked up after a year and aerospace offered no help, I throw it away and put on a Moroso one and have had no problems since i would recommened a moroso one to anyone.

Re: Vacuum Pump
 

Moroso 4 vane here. Works fine.

Re: Vacumm Pump
 

The inner bore of my aerospace pump grooved up bad when I was on alchohol....I had a machine shop bore it and put in a stainless sleeve which cured the problem....this was one of the early design pumps ....works great now....

Re: Vacumm Pump
 

After every day of racing when I put the car in the trailer I remove the vacuum hose from the pump inlet side and leave it off until the next time it comes out of the trailer. Then before I start the car I squart a little PB-50 in the inlet of the pump and put the hose back on. I also send my pump back to Moroso every winter and have them go through it. They always want to know if I ever use it much because it still looks new inside.
PB-50 is a general purpose lubricant made by PB Blaster. you can find it at most Home Depot and Lowes stores.

Re: Vacumm Pump
 

I am looking to put one of theses vacuum pumps on my Nova, does anyone have any pictures of how they mounted the pump and overflow tank on theirs cars? Just looking for some ideas and mounting options.

Re: Vacumm Pump
 

A defective vane would have come apart during initial factory testing. We test all new pumps at approximately 200% of a typical drag race duty cycle application, its one of the reasons we do it. If a vacuum pump vane does break its almost always due to something getting into the pump, other than liquid or air, that does not belong in there. The most common culprit we find is a piece of valve spring material. The foreign object breaks the first vane then these broken pieces break the remaining vanes. Its a domino effect. All vacuum pumps are vulnerable to this situation.
An appropriate filter between the engine and the pump would completely eliminate this possibility. You use an oil filter and air cleaner to protect your engine, why not do the same for your vacuum pump? If a needle bearing from a broken rocker arm locks up your oil pump is it the oil pumps fault? Certainly not!
Remember, you don't get filet mignon for the price of chicken. And if everyone bought strictly on price we would all be driving Yugos, and they would still be in business.

Re: Vacumm Pump
 

We put a Star pmp on Al Ackerman's F/D about three years ago........ I remember it working well and being worth about .12....... Hmmm.... wonder why we never put one on the L/AA when I was driving it...... go figure......

Anyway...... Star puts out a fine product and there is almost always a rep at the D1 races....... I'll probably have one on my car before the '09 season starts.......

Re: Vacumm Pump
 

Star makes a very nice piece. I have used Aerospace as well and my only complaint with them is they are not hard anodized on the inside and do wear a bit with use. I am currently using a Moroso enhanced 4 vane on my 1050hp 520" B1.

As for a picture here is mine. It is a bit hard to see but it is there under/next to the filter.

Re: Vacumm Pump
 

Thank you all for your advice. I wound up buying a kit from Reher Morrison with a 3 vane Moroso pump and the adjustable regulator that goes right on the pump. I am hoping you all can help me with one more question. What is the best way to adjust the regulator?

Re: Vacumm Pump
 

Your going to need a gauge
Try about 10 lbs to start, I'v heard to much will suck your gaskets in.
