Brettinator-
Def not what I thought it would be. I cant get an alt on the drivers side due to the procharger
Im ditching A/C and putting the alt in its place. I guess I assumed it would be the same setup im trying to do when I saw that idler pulley up in the alt's old location.
Tony-
Thanks for the heads up on the serpentine problem. I'll dig to see what I can find out.

Tony, I have known David Reher for about 30 years, so I talked to him and Bruce Allen before I went to a vacuum pump. These pumps came around after I quit racing several years ago. He and Bruce Allen are where I go to catch up on new things. They put me onto this regulator that screws into the Moroso pump in place of the fitting for the hose to the valve cover. http://www.rehermorrison.com/items/VacuumPumpKit.htm
With this you don't use a bleeder in the other side of the engine that can allow dirt to be pulled through your engine. No shims, etc. Simple to adjust. Bruce & David told me to use 12" to 13" of vacuum for something like a bracket engine, since the power gains drop off per inch of vacuum above that level, and oiling problems can crop up at very high levels. I guess you have the added wrist pin clearances, etc, needed to use a vacuum pump with no problems?
Looks like your vacuum pump hose is in the top of the valve cover? Looks wrong to me, especially if you think about the amount of oil the rockers put up there. They told me to use the front ends of the covers, or upper side, behind the pushrods. If you don't have very low tension rings (lower than what comes in the box as "low tension") the gains will not be real big. I see a constant 10 rwhp change from taking the belt on & off. That is just the belt, not including the ring pkg. Smokes a tad with the belt off, and with it on lately since the cylinder walls are pushed out of shape and the rings worn out. These blocks move around a lot when you lean on them. Not real stong.
I get almost no oil in my catch can when the rings are in good shape. Got some lately with the blow-by I have been seeing. Had it honed and am putting new rings in it right now to fix that. My hose is connected on the pushrod side of my pass side cover, between pairs of pushrods.

I couldnt agree more,we have the intake bung welded on the SIDE of the valve cover..I'd do away with it in comming in from the top too,14in is the limit for street strip setup w/LT rings not to mention the needed pin clearance which we have too.
I already had the moroso relief here and didnt wanna order the new style from David Reher but I do agree its nicer than my moroso relief valve as it doesnt use shims..Our puke tank get a very small amount of oil,maybe a 1/2 teaspoon every so often..

I don't see how it matters where you connect, as long as the fitting is not located in an area flooded with oil. Don't want to suck the oil out of the engine. Mike (and I'm sure the rest of the Pro Stockers) now use an electric vacuum pump, in addition to the vacuum stage in their dry sump oil pumps. It uses a Dewalt battery originally used in drills, etc. Last I noticed, it seems like he was using 28" of vacuum. When he was using a regular belt driven pump like us peons, his pass side cylinder head was drilled and tapped for the fitting so they didn't have to mess with the hose every time the valve covers were off. Which is every time the car goes down the track. Most everybody else uses the valve covers. Either the front or side. Avoid the top or rear.

That port leads down to the bottom and its entry is sheilded by a splash sheild.
Using it would probably be the best location to make sure you dont pick up oil.
Ed-
Electric Vacuum Pumps !!!!
That would make it a whole lot easier to package on my setup... Where/what kind are people using?
Brettinator-
I know about that one, it wont work as Im trying to keep Power Steering.
Cant afford the Madman rack yet.
I saw one somewhere that used the stock bracket, relocated the alt. down to the A/C comps old position, and kept the PS pump in the stock location. I saw the pic you posted and the engine almost looked identical to this pic I found a long time ago. So I ASSumed that it was the same. Thanks anyway We can stop hijacking tony's thread now

That PCV fiting is a tad small. Most kits use a -12 hose.
The electric pumps need recharged after each pass. Mike keeps one battery on the charger while running another one. Seems like it was a Pro Stock bike builder? S&S maybe, or George Brice? Just do a search. Looks like about everybody that fast in NHRA Pro Stock and Comp Eliminator has one now. They (users) are all listed in that web site.

Hmmm, I dont want to be recharging after each pass...
How about the pumps used for supplying vacuum to power brake boosters and such. Would they pull enough volume? I always assumed they were 12-volt anyway. I think summit has a few.
About the PCV fitting, it is slightly small for a -12an, but seems to be something easily enlarged if memory serves correctly on this one...
I'll have to look at my old Lt1 intake when I get home today.

Tony, looks like right now I'll be at HRP Friday night. Some Oklahoma City guys are coming, and I thought I'd run mine one more time with the F.A.S.T. setup on it before winter. If any of you Houston guys are there, look me up. I'll be in a pewter color old body-style ('99) Suburban, with a gray open trailer, black '96 TA with an Okie tag. Hope the track is prepped.

If I did not have to work Saturday morning I would drive down there to see ya Ed. That track usually is prepped really well. Good luck!
BTW............how do you like the XFI? You running alpha N or Speed density?

Speed density. Mine still has some vacuum.
A cam or two down the road, since I can spin it up, I may have to go Alpha N. Probably more gear also. With this small cam (compared to some of you ) it likes to be shifted at 7900. I think more converter, cam and gears it will perk up.
Take care, Ed
