Is this in a mod? Is it full of water, no air pockets? Is it the same temp guage from the old car? How hot is it getting?Is the guage right? Does it come in blowing water and steam or does it just show hot on the guage?

This is in a new mod, with a 355. Radiator is full of water with no air pockets. We thought it could have been the thermostat so we removed it and still had overheating problems. Car came in and spit water out of the over flow tube. Has anyone ever had a problem with there KSE pump not putting out over 5 psi at 3/4 throttle? At idle the pump is showing 2-3 psi, at about 4000 rpm its at 5psi.
Should we pressure up the system before we start throwing new parts at it?

Go to the menu tab in the upper left of your screen. Go to "search the forum" and you will find plenty of responses to your question.

I had the same problem with mine. The only difference is I have a Ron's belt pump. Anyways I spoke to the fuel pump guy at Poskes and he told me that I needed a two stage fuel regulator. What it is is a regulator that uses jets to set your idle pressure. If you have one what you need to do is warm the motor up and set idle at 3000 rpms adjust the pressure around 10 to 11 lbs, then adjust your rpms back down to where your idle setting is and jet the regulator for 3.5 to 4 lbs of pressure. I went from 220 deg to not even having to run my electric fan at all on a very humid and hot night. This should do it for you. At 7000 grand I'm at 13 lbs of alky and she runs cool. IF you have any other questions just let me know!

Hope you didn't pop a head gasket. Lean is NO GOOD my friend.

If you would quit running the you know what in your fuel you would not have this problem

You need to restrict water flow to get cooling gut a thermostat or put a restrictor(7/8 to 1" hole) where theromostat was and do not go too lean on fuel mix if you do not have put some airholes in nose raise timeing to 38/40

This is with a KSE fuel pump that was run on a car last year with no problems. And we have a restrictor in the water neck. The more I think about it it sounds as if our pump is the problem. Unless the fuel filter is stopped up for some reason.

What kind of pressure regulator do you currently have on the car?

Typical KSE bypass with the pill.


Thanks

I am running my fuel press at 5 psi idle, and were going to set the top end at 7000r's to around 9 to 10 psi. Maybe I am wrong on the pressure, but this is what the paperwork says to run that came with my fuel pump, and also what my engine builde told me to run. Is this wrong, and causing my motor to run lean, and dump alky into the crankcase then or does someone think I have my jets dialed to fat?
