The master is from a 87 S/10 application. Running the Corvette C5 front brake system requires more fluid volumn so the bigger bore master is a must. Don't really like the way it sits, leans back to much and hits the hood ever so slightly plus ur unable to keep the adequate amount of fluid in the front resivior, but u gotta do what u gotta do. Rob,:Smarty: What I mean is an underdriven crank pulley frees up alittle extra HP and ur still able to use the accessories with the stock pulleys. It's trully the best of both worlds for a street/strip application. Overdriven pulleys such as the one for the altenator causes problems at low rpm's. Since the pulley is bigger they need to spin faster to keep up with the vehicles demand of voltage. That's why mostly racecars only use the overdriving pulleys since they're not sitting around idling while accessories are running. Hope this helps:TU:
Joe that pic is of my brother Chris' car that we put together. 725HP mostly strip but it sees street duty too. Running the Meziere and a 90's Thunderbird two speed fan it never goes above *180 on fan's low speed. We actually took the car out on one of the big cruises around here last year and it ran cool in *85 with stop and go traffic. I think there are a few guys here that run that pump on the street quite a bit.
With dual fans and a big aluminum radiator, I've gotten away with the old Moroso electric belt drive pump on the street for years. Now the Meziere is on my shelf and from what I've heard it will do even better. Devon
Any noticeable Hp gain that'd make it worthwile money-wise for me to run the Meziere pump with a higher output alternator and electric cooling fans? I'm 99% street use with maybe 375 Hp in a '71 Riv.
Steve I don't really see what you would be gaining by going electric. Maybe a few ponies but on the flip side a bigger alt. to supply juice to the pump would chew up a little power.
Steve, For what u r doing stay with the original setup. It will be more than enough. The only reasons I did it was I didn't want the engine to heat soke after running it. So I went with the electric pump, cooling fans, 160 thermostat with a 170-210 coolant temp sensor. Ran the pump and fans off the sensor with a manual override switch so the coolant would cool in the radiator and then circulate throughout the engine cooling it till it reached 170. I'm anal about things so I tend to go overboard at times. Dave, I actually didn't know about a offset master. I'll have to look into that. Thanx a million it's been driving me crazy since I put that setup on.
Mike: I hope I wasn't misleading in my description. But the master is not offset. Just the reservior can be had with offset lower mounting nipples. I tried several versions to make sure I had enough fluid capacity and no inteference issues. They can be a bear to pry off the M/C, by the way.
Net gain is probably nil considering alternator drag, as has been mentioned. The benefits are 1. the Gee Whiz factor and 2. cooling the engine quickly between rounds (you can actually watch the needle drop while the engine is off, pump & fans running). Devon
It's great unless you forget and leave them on for too long.ou: The Optima doesn't like that too much. I know from experience.:laugh:
well back to my original problem.i thought i would reply with my fix.yes the gates belt #7430 worked great with (of all things) a crank pulley off a 350 buick i had sitting around.i measures 6 inches,compared to 7 1/4 for the bbb.the belt is far away from motor but slightly touches housing.should be ok.
I can see where touching the housing may be an issue. You may have to shim the alt and the crank pulley out 1/4". We are running .25" alum. plates from the heads to the frame on each side of the motor so we machined a .25" spacer for the crank pulley to square it up. I don't have a pic of the alt. side but the plate is the same on both sides.
