exact water path lt1
fabing a new mechanical pump for the car and it seems by the look and the fins on a stock pump water is pumped from the block outlets into the center hole of the water pump..... or is it the othe way around from the center hole of the pump to the block outlets you cant tell at all from the electric pump probibly why it didnt work so hot...i got a water pump from a 440 big block chrysler http://www.waterpumpwarehouse.com/se...-440-V8/Detailwith a little grinding and few wacks from my magic hammer it fits the stock housing perfectly all i need now is to mod the pump fins to optimize water flow...and wala a belt driven lt1 water pump no more cam gear failure!!!!!

i dont think so but i have heard people hate the gear drive. just heard the material of the aftermarket timing chains are incompatable with the gears for the pump..if u use a lt4 extreme chain it will work gm part..if this is true its just another incompetent move of aftermarket parts manufacturers.......i should sew thoese guys for 2 motors ......they know they dont work........ like moroso's electric 1 way 2way accusump valve they now it dosent work but they keep on selling it...

any way the mechanical pump seems to me would run in the oposite direction of the motor because of the cam gear,, OR is there another gear that is involved to match engine rotation direction????

His father Dick MOROSO the founder back in 1968 was a NHRA Super Stock Racing Champ.
Not everything made by MOROSO for Drag Racing works just as well for high speed Road Racing.
Herb Adams & his company VSE was selling his road race & suspension products through MOROSO till just a few years ago.
dissapeared from the master catalog.
Herb Adams invented the 1969 Pontiac Trans Am.
His creation start to finish.
He brought high speed handling to an American car 1st.
Out handled the Chevy Corvette in 1969.
Did it with a straight axle rear differential too.
He was an avid road racer.
Never quit.
He like Corvettes also.
dabbled heavily with them also.

Everyone I have ever seen & replaced,
leaks again down the road and right onto the OPTI SPARK UNIT.
Great idea on blueprint paper.
Proven in the real street driven & race world,
horse crap reliability for both.

I would like to see that entire goofy C4 LT-1 cam driven water pump scrapped somehow.
Everyone I have ever seen & replaced,
leaks again down the road and right onto the OPTI SPARK UNIT.
Great idea on blueprint paper.

the point again is it didnt work at all they knew it and keep selling it an accusump works the same but used for two different reasons..in drag racing its just usually used to pre charge the motor.. in road racing it is used to back up oil press when u corner or brake hard...
It has saved a few drag race motors that I know of.
That ficken accusump is no primary oiling system tool for a C4 road race machine running 140 to 180 mph.
That jackass that sold you that & told you its just as good as 3 or 4 scavange dry sump oiling system needs a kick in the rear from you as hard as you can.
When he gets up,
kick his *** down once again dammit.............
He ficked you bad.
I am sorry.
But its the god damn truth from me.

That SOB accusump is a last resort, pull all stops, let go of the steering wheel at 180 mph & put your hands together & pray before you hit the wall at 250 ft/ second and become ashes to ashes>>>. dust to dust .

ah...it was one of your friends here. he on my side that a drusump is too expencive and an accusump is good enuf...ive seen dosens of road racers use them. with sucess.. my oil press light comes on at 35 psi. when i had the canton electric valve (theirs work) it would open the valve at 30 psi.. i would corner hard light would come on...valve would open light would go out.... i cant find anyone who has dry sumped an lt1 im not going to be the guine pig on this issue too. if i can find someone who has done it and it worked well.. ill think about it.untill then no....ARE has not sent me anyone or any company who has done it before....ive heard there the best at drysumps...
Success with a wet sump oiling system this time around OR
#8 engine blown to smithereens.
I would definite dry sump this time around.
Following the crowd has done you little good with the last 7 engines.
Time will tell.
My bud Steve says Dry sump is the way to go for You also.
Kicked it around Monday after work till 10 pm night with him.
He knows wet sump systems suck bad when cornering at very high G forces.
Nothing like having a billet connecting rod & JE piston go through the side of the block & oil pan.
Everyone I have seen that way have wet sump pans attached.
You tell Me George.
You pocket book.
You Ego too at stake, not mine.

Why would you even want a mechanical driven water pump? Why not just go with a Mezier electric water pump for a lt1,it's proven works and free's up horse power too. Oh and the hot new thing for Mopar 440"s now is a reverse flow adaptor plate mounted under a electric water pump. Guess what water pump they use, yes a electric water pump for a Chevy!

Personally, I'm a fan of electric water pumps for racing. All I had to do was look at the billet impeller on the Meziere vs the stamped steel impeller on the stock pump. It has got to be a lot more efficient. But Trackman must have something on his mind. Maybe the Mopar unit has longer impeller blades or something.
I like the electric because once in the pits you can slap on a charger and, with one switch, turn on the water pump and the radiator fans with the engine off. Cool the engine down in about 10 minutes.
Typically if an engine is overheating it's a function of the radiator and not the choice of water pumps. You have to enjoy the creativity of racers. Sometimes problems can be solved by folks that have to make it work.
