hey guy i have a 1996 12v and i have a 5in mbrp pipe running only 28psi of boost stage 2 afe intake after market injectors (big) and my afc starwheel wide open and when im cruising my pyromter can hit 1000 degrees just cruisin at 2 psi of boot on freeway any way i can lower the egts i was thinking about aftermarket exaust manifold what you guys think

 

Adjust timing, and maybe back down the start wheel. also where is your pryo at is it 3/4 to one side right smack dab in the middle or behind the turbo.

Unburnt fuel eguals more heat, tune it better and have it burn all the fuel so it will run cooler. How big of injectors do you have? also because if you dont have the proper timing, air, those injectors are just dumping fuel... Hope they are no more than 90 horse.

 

the timing is stock from factory injector came with the truck i had them ebuild all we could find out about them was that they pop off at 360 and i think there bigger thsn 40hp forsure once i saw 40hp injectors pop at 310 or 290 i thik it was

 

360 is way too high of a pop pressure 260 is prob what there set at as for running cooler you need to tune your afc and not have it set as loose as it can.

 

ok will do thank you guys and what would you think of a aftermarket exaust manifold on a stock turbo

 

not worth it

 

alright thanks for the help

 

I have one because I had my last one crack. Notice slightly faster boost but thats it..

 

what about the egts what did they seem to be like

 

Sat the same, what made a difference was straigh pipeing it they dropped 100 degrees at 65 mph
