Was it that one Blue ?

It was the 35gph Meziere, couldn't keep it cool anytime, anywhere, especially cruising at 60mph.....

wonder if the 55 GPH will be different

Well had a Mezziere unit mounted in a mopar pump housing. I had modified the housing due to the elimination of the top hose from when I had a Jesel distributor. So basically I had to 2 hoses replacing my top hose feeding either side of the pump. Not sure if this was the reason I never had issues.

Although I was happy with what I had, I decided as now going on the road I would increase the capacity from 35GPM to 55GPM & also to go to a reverse flow pump to cool heads before the block.

I have heard good feedback from other owners who are using the same designed reverse flow pump. 2 of these are running on the street, one has a 572 hemi similar to mine, except hes makes more power than me & neither have had any issues.

Blue, What were your issues, was it the standard 35GPM pump or was it the same 55GPM reverse flow

Ooops, posted same post

Ooops, not sure what I'm doin here, but the same post was posted again

Maybe because it was 35 Galls per hour hour & not Gallons per Minute

Sorry, yes that was GPM! What's the deal with reverse cooling? Is it more to do with detonation prevention rather than overall engine temperature? The problem I had was that I could barely hold the temp at 200 in traffic and at a steady 60mph the temp would gradually rise until after about 20 minates I'd have to kill the motor and let it cool down. At that speed an engine driven pump is flowing around 90 GPM, so I'm sure the Meziere's 35 was nowhere near enough.

Blue, your correct, the main benefits of reverse flow is to help reduce detonation & hot spots, but the 55GPM should also help with the cooling, when comparing to 35GPM.

Reverse cooling was one of the 1st things the Lotus engineers did when there were assisting GM with the Corvette. Think they also picked up 30 odd extra horsepower as well. Due to the allowance of additional timing,etc.

I have large frontal area on the Cuda, plus with my homebuilt alley rad & the new pump I was hoping this could alleviate any fears I had of running hot. I guess the proof will be in the pudding

If not then will have to revert to plan B, not sure what that is, but will definitly be a plan B

And by using 4 valves per cylinder and dual setting on the Injectors and ECU chip ETC ETC

And i have a pair of their prototype ZR1 heads who given to me by my cousin, who also found 2 crushed proto type ZR 1's which he went on to restore to original spec, and then take to Bowling Green in U.S.
Chevrolet wanted nothing to do with them although they are theirs.
Although destroyed.....but not enough by Lotus at a scrap yard in Norwich,
The Ramifications of these cars reappearing was to much for Chevy to accept
This is Gospel

Havent given much of an update recently........ to busy spending my time as a Number plate spotter or more to the point still stuck in Polditz. Thought I had a great escape plan, but looks like that has been scupperd & wont now escape till Sept

Well, the exhaust system is finally finished, went with a 3 1/2" system into an "X" then into four exhaust boxes, 2 per side. I assure you its all a bit tight under there ! Hoping system I will quieten the motor down some what, but not too much

Had to change the rear locator to a sliding link type, as exhaust box fell right in the way.

Need to get the car down on the ground to check how much ground clearance I have, but guess will have to raise it a couple of inches


Fabrication of a new fuel cell is next on the list. I looked a buying a pre made unit, but couldnt get capacity I wanted or more that the size & capacity wouldn't fit in the available space. Not sure how many gallons to the mile cars gonna do, but want at least a 25 gallon tank.
Then can start installing all the fuel system parts, which have been sitting in their boxes for the last 4 - 5 months.

Also scored or should I say got some new Polycarbonate sheet coming to replace all the windows, as the old windows are starting to get a bit too much scratched for my liking. Should have enough over to do again if need be

Then the next big step is the wiring, was originally thinking of adding to the loom I made. But decided to start from fresh, more £££'s but think end result will be worth it.

Only a few weeks now till Wheels day, all being well I hope to make it. Should I say I have my fingers crossed Andy gets the car done in time.

Still working in Poland, but off to the the States in 3 weeks, so will eventually get the chance to pick up my new water pumps. If I can find some , will try & hand carry some new wheels home, gotta make the most of the strong pound while it lasts

Will post pictures as soon as I can, but wont be for a few weeks I'm afraid.

Cheers Mark

Well still havent seen the car, only verbal update I'm afraid.

Like I said before exhaust is completed, headers away for aluma coating or what ever you call the stuff.

Fuel tank is finished & fuel system is now nearing completion.

Big stuff 3 now in the US, so it can be modified to interface with my Ultra dash.

Another bit of good news is that BigStuff3 have a guy in UK I was unaware of, so trying to get him to come down to run through the system, hoping hes got a few tricks up his sleeve

Got all my new windows cut to approx size, this time used Marguard coated polycarbonate material, so should help prevent scratching some what .

Home on the 21st of Feb'08, so will post a few pictures on the 22nd/23rd or there abouts.

Cheers, Mark. . .

roll on the 22nd..

Mark, looking forward to it.

Well got the camera on charge ready for the trip to see the Cuda tonight, hope I'm not too dissapointed with the progress

Will post pictures of car later

Got a nice surprise today, one of my friends who works in Boston is working in UK next week, kindly hand carried my water pump for me, so collected earlier today

Well that's one less thing for me to hand carry next week
