egts
 

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:argh:

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:jump:

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

crossdrill the wastegate and they will drop more than that

YA I wanted my turbo to last... lol but its your rig..

a bigger down pipe will help also.

crossdrilling helps the turbo last longer well worth the time to do it

For now, if I were you, Id back off on the starwheel. 1000 degrees is way too hot for 2 psi of boost.

ihave the mbrp 4in down pipe on a 5in pipe all the way back

i found i put my pyrometer befor the turbo so i read the temp before it goes into the turbo

i have my pyrometer in before the turbo so before it goes threw the turbo so i hear its normal to have a higher temp read there.:humm:

Ya a pre turbo pyro will read hotter than a post pyro because it cools down when it goes thru the turbo

I will have to look into it.

its just drilling the wastegate hole to vent all 6 cyl in stock form it only vents the back 3 cyl when the gate opens

the back 3 are the hottest runin tho arent they

coolent temp they are the hottest yes but egt temp should be close to the same

ok
