Currently with the rear mount, my IAT's only get up to about 15* over ambient. What kind of IAT's are you guys seeing with front mount turbos?
my last setup usually seen on average 15* above ambiet when under boost for a full pull. the times when i ran e85 mix i seen the IATs drop below ambiet on a full pull.
IAT can be effected by how effecient the setup is

same way as any other alcohol based fuel. If you noticed when running an alcohol based fuel most dont run a IC as its not neededQuote:

Trust me I am not arguing, I can see cyl head temps or EGTs lower, But IAT's?
If you tell me that you have datalogged the fuels back to back, I will take your word for it. I am just struggling to comprehend how.
That's what I figured - intercooler size, pipe routing, etc. I'm just trying to get an average here so I have an idea of where the IAT's will be when I move the turbo.Quote:

Might consider water to air with a front mount. Much shorter pipe routing. Less pressure drop. More consistent temps = Less tuning issues on multiple passes or possible heatsoak
The plan is to keep the intercooler setup like this
Attachment 3718
I'd like to run an A/W intercooler but the cost is the only thing stopping me. Keeping this intercooler is free. I also plan on relocating the IAT sensor to directly in front of the throttle body, mainly so the ECM will recognize the temp drop when the meth sprays.
who cares !... Go front mount and sell me your Old spare oil pump !.. If all u change are hot pipes it will not be much of 10 up or down of where u are now........ and like Allen said.. depends on your IAT sensor location and you have Meth kit anyway so WHO CARES ! Hurry and go front mount !... Allen Claims 100hp Gains over the Trick/KBracing stuff........ Put him to the test....
Where did that come from? I claim 100hp gain using my avalanche going from the rear mount, to my front mount kit, at anytime there was no mention of the kb/trick kit comparison.Quote:

Not backing up Quik, but comes to my attention, then when I use pure Avgas 130 I see a 2 degrees drop over normal Pump gas (92 oct). Weird, but is on the logs !!!!!!
That really is wierd. I don't see how the ECM can read the temp drop.Quote:

EGT temperature changes may have an effect on IAT's. Not sure which grade of avgas fuel you use but it may burn cooler. Alcohol burns a lot cooler. Keeps the turbo cooler so naturally IAT will come down.
Where can you get 130 Avgas? I know an airport before you smart asses chime in. If I remember you aren't in the states, right?Quote:

I have a little hangar with 2 flying things in it, in the Intl Airport from the city I live, so from time to time I get some fuel for the truck. I purchase it like if it will go to the crafts, but instead I use it in the truck and the Camaro from time to time.
I buy the one in green, that is suppost to be for the turbo charge and SC planes that the AirForce here have for training (old rigs). They also sale the blue one avgas 100LL but I prefer some lead in my diet.
When I first recive my 408 form Nelson, I had no good tune to part with, so I choose to drive with avgas all the time till the tune got safer. So in that time (a 2 month), and prob a 2000 miles at most, The fuel ate 3 WB O2 sensors. The OEM O2 are long gonne, I have a SD tune.
SO I can tell you that if I daily drive it with AVgas, prob 2 weeks tops will chew a brand new O2 WB.
I got my self like 12 I bougth as spares in my garage.
Now with a safe tune on 9psi on pump gas and meth kit, the O2 WB has last 3 month till now, and still working. Had load the truck with the leaded fuel like 4 times most.
