personoo

i finally have my turbo up and running but the engine temp is high, 210 deg and slowly increases is this normal? i have a 82 trans am with a 400 sbc,pte 88 turbo, home made headers,griffin radiator,evans coolant,meziere w pump, ford crown vic fan,fast electronics w/ 72 lb/hr inj,afr 210 heads,400 hydro trans, air to air intercooler, turbosmart wastegate and bov and also alky control meth kit.
my car was supercharged with a procharger F2 but i changed it and my temp stayed around 160-190 never over. i'll try to send a few pics.

THANKS FOR YOUR HELP

Im sure that turbo is generating ALOT more heat right by that rad then the F2 off to the side of it was. I'm no big help on how to cool it down more maybe try havin the fans kick on earlier/more often. Or all the time. better shrouding to pull more air thru,etc....

How about some more pic's of the headers and setup That looks very nice man.

The exhaust restriction of the turbo makes the engine run hot[ter]. My first twin turbo setup used t3 .48AR turbines and I had heating issues seeing temps near 230*F with the fan always on. I made better flowing headers and upgraded the turbos to t3 .63AR turbines. Now coolant temps are easily controlled with a JET fan switch on@220*F (off@180F). I also have a stock radiator and a 160 t-stat.

I wouldn't think your turbine housing would be a significant restriction (just by observation).

I've heard good things about highflow waterpumps for cooling. Also a waterpump going bad causes hot coolant temps.

You're probably not running lean with those injectors. Lean conditions cause heat.

I read in a book that oversized cylinder bores increase coolant temps too.

Sorry if this wasn't helpful, because its probably stuff you already know.

What else did you change at the same time?

You could expect a small change in running temp going from blown setup to another, but that’s a bit extreme…

Does that whole deal fit under the stock hood? Any other pictures of it?

personoo

the only change was the turbo which is a t4.also my hood is a glasstech with a 4'' cowl . i'm leaning toward a faulty waterpump.

i want to thank all of you for your sugestions you've been a big help.

i will try to dig up some more pics of the car and headers,by the way the headers were made to use on my single and twin setup that i will finish this winter ,for now i just wanted to enjoy the car and my hard work.

out of curiosity what is the AR of that T4 turbine?

personoo

i'm not sure its 96 or 105

here's a few pics of the car.

Try shaking the water pump pulley with your hands or listen to the pump with the engine running. Excessive play or rattling in the water pump are dead giveaways. Also, slight (or excesive) leaking out of the bottom of the nose, where there is a pressure release hole, is a sign of waterpump failure. you probably already know this too.

personoo

there's no coolant leaking from the pump and i'm using an electric pump
(no pulley)

Huh, and the rest of the engine is the same…

I’m assuming that you ran the intercooler before?

With an electric pump in most cases it would be working or not, and if not the car would overheat quickly. Is the cooling fan turning on? Any chance the front air dam got messed up or something?

I really like the exterior of your car, what color is that and who’s notchback is that (I’ve never liked a notch back on any of them before that one)? Is it tubbed?

personoo

yes the car is tubbed with a ed quay kit and 14.5x31 in the rear.i bought the hatch some years ago from motion glass and the color is called persian red pearl by ppg.

i did have the intercooler with the supercharger and i did remove the air damm ,i wasn't sure it was making a difference with the intercooler there.i will replace it.the reason i was thinking the water pump is when the pump was on i couldn't see the coolant flowing and when i checked later i could see the coolant flowing and the fan is working.
