Ok got a friend he don't post but watches on here. His iat's are 230 deg. He's got the zzp h/e 60lb injectors 2.7 pully. His pump appears to be working right so anyone have any ideas? Thanks.

 

holy **** 230??? Mine are around 120 and I think that is too high.

 

Ya I bleed his system for about 30mins and still to high. Ic pump appears to be working fine

 

Something is plumbed backwards or his pump is in fact not working

 

Yea when my pump died i hit like 160 max lol something is wrong. If you bled it, i assume you saw the coolant moving? check the plumbing for kinks, if its plumbed wrong and if you can see the coolant moving

 

It was moving. Up down looks like Its flowing

 

yeah i have an idea. all he has is a h/e on a 2.7

 

or he has them switch backward meaning hs the laminovas fcing wrong and the hosing up wrong if he has a h.e ... Or he dont have any cooling mods.

 

hey lets james lets go look at that vette some time this week!

 

Sorry to thread jack but how exactly do you check iats?

 

Yeah, I've seen mine up to 220 with dual pass, option b and ZZP stage 3 he, but I'm pretty sure my pumps fried, so I just take it easy on her for now until I can crawl under there and replace it. Maybe I'll try the hammer trick first and see howthat works out lol

 

okie dokie, i might be riding up to fort wayne indiana Soon this week to do a stage kit insall on a lsj and tune him. So ill let you know.

 

Interceptor

Even with a 2.7 with just a heat exchanger it shouldnt go that high. With just a cobra H/E the highest I ever saw on my 2.7 M62 was 164* or something close to that, and that was a 2-3 and some or 4th gear pull

 

Its a bad pump or a lot of air when my pump went bad I saw 220 deg iats with the 2.7 when I replaced my pump and I had a lot of air I saw 140 now I have a kind of option b and all the air out I see under 100 ait2

 

My vote is bad pump. I had the same problem. It is a common problem with this pump. The pump is made by bosch and is the same pump used the the ford lightening, the mustang cobra sc, and all kompressor mercedes benz's. I have checked many forums for all those cars and they ALL complain about the ic pump failing. The pumps are only good for about 50k if you're lucky. I believe ZZP has an aftermarket pump that is better than the bosch but I gotta research that more. Also I am trying to find out if the ZR1 uses the same pump we do. If so, I know that there is an aftermarket ic pump for the ZR1. Anyway, the pump is more than likely the cause. If not, then air in the system or plumbed wrong.

 

wasting your time, by the oem bosch one from zzp or from blue oval insdustries call it a day, and use the left over cash for meth kit

 

I dont consider it a waste of time if I find a pump that i dont have to replace every 50k or so. And I bought mine from ford racing products. $99 incuding shipping. Best price on a new oem bosch pump anywhere.

 

okie doke

 

Even with a completely dead pump I cant see iats that high. With my pump failed, 90* heat and hard driving, mine never went over 180*f and my iat reads ~20*F too hot. This is with a 2.8" pulley I think there's larger issues at work, like a non functional bypass valve.

 

What about a maf
