Re: SVX Engine cooling "Again & Again"
Also I agree with Tony's analysis.
Too much heat on one side, or ineffective cooling on one side, however you want to see it. [I'm sure Tom meant to agree with Tony, not Harvey? Tom?] Joe

Re: SVX Engine cooling "Again & Again"
I meant that Tony was the one who asked for a specific Agree/Don't Agree answer.

Re: SVX Engine cooling "Again & Again"
Agree. Lower flow through left bank. Probably causes local boiling.

Re: SVX Engine cooling "Again & Again"
Okay, today (it is now Sunday 6.30am) I will change the pipe on the top of the engine. Based on what we all agree if the tempreture of the left bank runs cooler then the right bank it means that the flow has become higher then the right, if on the other hand we get the same tempreture in both heads we would assume that the flow is constant. So lets see what what happens will tell you at the end of the day.
The reason for asking if everyone agrees is that we can"t flow test left and right bank that easily so we need to all agree that there is a different method to find the answer. The Biggy for the day, Second point I need some Hp power numbers of the standard engine at different rev, 2,000rpm, 4,000rpm, 6,000 & 8,000. I would also like them for the target engine. I have been thinking about what Rally Bob said and think we need to build a quick & dirty, Tony "type" rough computer model to show us what would happen under different scenarios. It won't matter is the Hp number are right or not just that they are indictive of the engine. The model will deal with the follow variables and I was going to us excel. Change in Engine Revs, Changes in air tempreture past radiator, Change in coolent flow rate, If anyone feels like giving it a go please speak up, other wise I will start on it tonight. Have a great day team. Tony

Re: SVX Engine cooling "Again & Again"
Harvey,
Think of the moded one that Tom posted a photo of first. Haven't got the time and parts to build a "T" one today but want to see how the simple mod goes as step 1. Tony

The pressure does not rise at a linear rate. Cooling deteriorates accordingly on a slippery slope, at hot spots and points of resistance, as a result of increasing pressure. Balance within the system is upset to an increased degree, as a result of increased pressure. Cavitation at the pump is more likely at increased RPM, against what is a fixed resistance. Increasing pressure in line with RPM, is surely the essence of the subject.

Re: SVX Engine cooling "Again & Again"
Harvey,
Forgot to ask, any ball park guess on the HP numbers, it just needs to be a best guess. Tony

Re: SVX Engine cooling "Again & Again"
A stock engine generally produces somewhere in the ballpark of 175 wheel horsepower if it is in good shape w/ a std. trans. Around 160 w/ the auto

Re: SVX Engine cooling "Again & Again"
Well the cross over pipe didn't fit, its to high as was suggested. I need to cut and weld to get around the problem.
Any way I will photograph the fix when done and keep you posted. Tony

Re: SVX Engine cooling "Again & Again"
Sorry for going off before I was unfair.
Good news, I got the pipe changed this morning and drove the car to work and guess what the left and right bank were running at the same temp. It was possiable to sometimes see 1c difference but was either way, above or below right bank temp. Other interesting thing is that the dash temp guage ran slightly lower which would indicate to me that the thermostate is functioning better. Hooray team we have progress, we are heading in the right direction on this project. So what next? Have a great day. Tony
