Wasn't asking about coolant temp, sorry - I assume, tho the engine is at least riding on the stat and it is still stock spec.
Just curious about charge air temps in/out of the IC. I use a gauge with dual needles and sensors on the IC in/out.
Do you just want improved flow thru the IC, or better cooling? One of Ken's dual-core ICs would be interesting to try.
And sure both better flow and better cooling, but when you improve flow, you loose backpressure, which leads to less boost on the gauge, which leads to more pulley, which leads to higher ACTS, which leads to more IC, which reduces backpressure, etc. etc. Back on the cascade/slippery slope train. The best way to stay off that train is to avoid doing anything that aggressively dumps heat into the charge air in the bargain. I'd want to do all I could to not add more heat, while removing as much as possible from what's already there, first. If that results in more flow, fine, but in your example, I'd resist higher flow as a primary goal.
A raised top will -modify- flow, but just keep in mind it isn't so much an adder as a means to shift the power band higher. I like mine, but as I said, it moved the power higher in the rpm range, taking a bit away from the bottom, but nothing 7% over didn't cure, keeping in mind my goals are different from yours.
Are you still bound by a rules budget?
I understood what you were asking on the ACTs, I just kind of went off the rails with the whole coolant temp thing. But what I was getting at is that the car runs so cool on the ethanol that heat isn't much of an issue even with the ACTs being super high with the 15% overdrive. The ethanol burns so cool in the chamber that the car never even gets hot. It barely moves the gauge even after a pass. I did not mention that I never even turned the cooling fan on this past weekend. Back when I would run 110 octane gasoline I would have to turn the fan on in the shut down area and keep it running until I started my burnout for the next pass. On the E85 I am thinking about just removing it to save weight, it is that much of a difference.
Interesting you say that about the raised top. It desperately needs the high rpm power. Maybe I need to get one of those tops and work on the intercooler. I think anything to increase the flow at full tilt is going to help. I like the idea of a double intercooler because I can keep the stock look but on the other hand, I can get something like an Isuzu NPR cooler for about $100 and then make my own tubes. I am not sure what I will do at this point. Sounds like the raised top might be a first step.
I am not trying to stay in the $500 budget at this point as that junkyard class has gone away. I definitely have more than that in the car now but at the same time, I would sell the car all day long for the $3,000 that the Roadkill event stipulates. I am hoping I can get in one of the Roadkill zip tie events in the future but I am certain I will need to be in the 11s to win one of those.
