Wow look at those IAT's!!

Glad its running well.

Yea, they are still high but actually about 30* better than they were previously. That could be from the different h/c characteristics, less manifold pressure or the fitting modification I made at the intercooler for better flow. I have some other cooling mods/upgrades to do to the a/w system but wanted to get some good data with the new setup so I could have a more apples to apples comparison.

Is your intercooler pump running? What's your compression again? Those IAT's with 20.5 advance.. Umm, I would be worried. Even on e85.

I presume so. It is running when can check it at idle so unless it is cutting out under thermal load, I don't see why it wouldn't run all the time. The temps recover pretty quickly after a run and hover about 50* over ambient.

By my calculations, SCR=9.480 DCR=7.438.

It must feel strong with 20 degrees of timing and 12 psi! I too would be a little worried about the intake temps. Where is the sensor located?

Maybe it popped out and its resting on your header...

Your IAT's are really high! Mine run 16-20 above while cruising and climb to 60 above after a 1/4m pass. My old Kenne bell ran your temps without a intercooler, that can't be normal.

My IAT's have always been high. There is lots of discussion on here and other boards about twin screws having higher IAT's due to constantly compressing the air and recirculating it out of boost and also about the KB's temp sensor location in the lower manifold between 1-3 intake ports causing false readings. Some of my high out of boost IAT could be contributed to my intake/filter as it is not completely sealed off from the engine bay. Without substantial and accurate data, I have nowhere to pin point a cause. I have a plan to add a few temp and pressure sensors in the system to measure with the E/I of my HPT cable. Once I have that data, I will have a better understanding of what is happening and what I need to do increase the efficiency of the system. Without that, I am just making assumptions and changing out parts.

BTW.. those of you with TVS', what IC pump are you using? Flow rate? I am still using the KB supplied Johnson CM30 which specs 5.9gpm @ 2.17psi head. I have no idea what my head pressure is but I presume it is more than 2psi.

I just have the standard Bosch pump that everyone uses, I would have to look up the specs. Can't imagine pressure is much if anything. Appears mine flows 317gph so just a tad less then yours.

Just my opinion, but I would look at what 03' Cobra's do with Kenne Bells. If you look at my sig I mainly do drag/ street cars. My Best friend is TMANGT281 the highest 2V GT hp in Colorado. He is a KB 5.3 modular, he runs a 2.6 with this intercooler and his IAT dropped insane. He has it setup to run off key on ignition. So it runs all the time, but the IAT drops were out of this world. If you call KB alot you can ask Mike@KB about Tyler Mantz's 2V and get his opinion on how much power that car puts down and how they had such a hard time keeping it cool until they upgraded the heat exchanger.

I can tell you when I ran my whipple, it would burn the skin off of your hand. I upgraded to this intercooler before I sold the car, I never got a re-tune on the car to see how much it changed, but you could sit your hand on the blower and it was hot, but nothing like before.
