I'm about to finish up my '92 notch. It's a N/A 331 w/10.5:1 comp, Edelbrock RPM II, AFR 185's, & an XE282HR cam. What would be the best water pump set up for my street/strip car? I have a March underdrive pulley set. I'm only gonna run the crank, alternator, & water pump. No smog or power steering. I heard somethin about runnin a reverse flow water pump or vise versa, can't remember exactly. Any opinions &/or pics of your set ups?
Stock, our cars run reverse rotation water pumps. I'd assume you'd have to keep that "trend" We will be putting a Meizere (sp) water pump on my 347. Electric would probably work pretty damn good too.
I have seen guys put standard rotation water pumps on so they could delete the tensioner and run a shorter belt. March sells an adjustable alternator bracket so you can set the belt tension. It's a clean looking setup. I'm with Runningmole though, it doesn't get any better than the electric pump setups out there.
I had the march kit and also tried reversing the tensioner. I switched to the standard rotation waterpump, and that is the best way. Looks the cleanest too.
Are the electric pumps OK for the ocasional street cruise? Id heard of people saying its not good to use them on a driver, just wondering if there any truth to that or if there are certain models that can be used?
So the stock pump is a reverse rotation? I guess I'll try out the standard rotation, anyone know the part# for it? And if u remember the belt's length?
From what I hear, the motors in electric pumps burn out pretty quick. So there good for drag cars and ocassional street use. As far as waterpump rotation I wouldent know anything about that. However, if you do have any cooling problems you can always swap back to the stock waterpump pulley. High flow waterpumps are just powerrobbers IMHO, but thats if you have a quality radiator. :OT: Just curious, have you dynoed your car yet? If so Whak kinda numbers did you get and what kinda trans do you have....I ask because I have a 331 too w/ same heads ( and 10.8:1 comp.) and plan to swap my puney performer for an rpm II also, if you could throw in your cam specs that would help too. Just trying to get a hp estimate.
I have'nt finished assembly yet. I'm about to order an RPM II really soon. I got my short block a while back from Wynne Speed. It's a 331 w/Eagle 4340 crank, H-beams, & SRP pistons. My compression should be at 10.5:1 w/the out the box AFR 185 (61cc) heads. The cam is a Comp XE282HR (232/240 duration, 565/574 lift & 112 lobe seperation). I'll be runnin a C&L 76mm w/elbow, 75mm TB, 30 lb injectors, BBK 1 3/4" LTs, 2.5" H, & Magnaflow 2.5" CB. Everything is out the box except for maybe opening up the TB inlet on the intake to match my 75mm TB. As for my notch I have an AJE K-member, D&D A-arms, Strange adjustable struts, X2C front & rear coil overs, X2C Boxer ST upper & lower arms, 50/50 rear shocks, 255 in-tank pump, stock T-5, & 4:10 gears. I'm hopin for 11's!
I have heard the CSI Electric Waterpumps are good for about 50K miles then you need to rebuild them. I think the main advantage of an electric waterpump would not only be to reduce drag but that you could cool your engine with the engine off.
The Meziere electric pump is supposed to be awesome. Direct bolt on, flows 55gpm, you can get it with a free wheeling pulley to run your belt the regular way or without whichever you choose. It flows higher and is advertised as a street/strip pump being most likely because it flows a higher number than the CSI which is about 37gpm I believe. Only down side is it's $435 as opposed to about $260 for the CSI. I have an Edelbrock high flow pump on the car now but will be switching this summer.
Ford Racing has a water pump that flows 30% more than stock, I believe it is reverse rotation: p/n M-8501-B50 Summit - $174.88
