What does it mean when my Exhaust manifold glows cherry red?

My EGT when I first start it is 6, but after driving it for 8 mins it climbs to 10.

At that point, the MR2 T hesitates under any boost and the exhaust manifold is red hot!

What gives here?

PEACE-

 

need more info... what are ur mods? how much are u boosting? manifold is glowing red cuz obviously its very hot. my friends mr2T used to do that, but only after running hard on the highway for a while. should of seen the flames coming out of it. twas awesome

 

Stock Boost.
Original Exhaust.
Air Filter
B.O.V.
Fresh Rebuild
No Smoke

If you drive it for about 10 minutes with no boost, you get a red hot glowing Exhaust manifold. If you boost up, then it get hot quicker. So, I'm not driing it right now until I figure this out dude. Also, the car runs 3/4 hot on the temp gauge. Don't know why?

No Coolant leaks
All coolant hoses replaced
Radiator fan turns on, but just for a few secs and at a very low speed
New water pump
New thermostat

How do I read my EGT gauge? It climbs to 12 in under 10mins.

Whats wrong with this new rebuild?

 

Sounds like your timming is really retarded ...

Check base timming

 

Ok,

What is a normal reading? When do I know something is wrong?

PEACE-

 

Alright for some reason your car is running really lean so you might have an intake leak somewhere. your injectors might not be firing right and dumping enough fuel. anything that could create a lean condition would cause your manifolds to glow red. even a minor intake leak could casue this. jsut keep that in mind in your diagnosis.

 

My car has a high pitch whistle coming from the throttle body. The sound seems to be INSIDE of the throttle body. My EGT gauge has been reading 15, which maximum on that gauge is 16.

This shit ain't right, dude! Any ideas?

 

its an intake tract leak that is casuing more air into the system after the maf therefore casuing it to run lean becasue there is more air ggoing into the motr than the maf accounts for so it is getting way to hot.
