I called Summit a few weeks ago to check into the possibility of doing this, and they said that it was no problem, so the actual part swapping part of this dilemma isn't an issue. What I'm trying to decide on are the pros/cons of going one way or the other.
Now typically, when I post one of these I get hardly any advice from the collective, and this one may be the same. Given that I'm talking about intercooling vs not intercooling, I at least hope those that have a S/C-T/C will at least chime in....
Anybody who has looked in on my build thread knows that I have this elaborate, rear mounted heat exchanger w/ a 3 gal water reservoir, and a Bosch recirc pump running water to a front mounted A2W I/c mounted under the driver side front fender.
I'm running an inline F/I mallory pump that will feed pump premium through a -6 line, feeding (6) 60 lb EV-1 injectors, then return it back through a -6 return.
I'm concerned that that was not a wise choice, considering I want to drive the snot outta this car.
An A2W I/C in a closed loop system like mine will start to heat soak. Whatever the fans on those rear mount radiators are capable of cooling the water to will be the average temp of the recirculated water. That will be at least ambient, more than likely well north of that after I heat that water up when I put my foot in the throttle and boost starts coming online.
This being a weenie six banger, in order to make the targeted HP/TQ (which is low when compared to V/8 numbers) 400/500 RWHP/TQ, I'm gonna have to make alot of boost comparably speaking......like 16-18 P.S.I.
Air compressed to 18 P.S.I is hot, and the I/C may not be able to relieve that much of the heat once the water temp starts to rise in the closed loop. The heat exchangers get their air from "gills" that are molded into the quarter panels infront of the tires. One of these gills is done, the other, still needing to be built.
A2A is not an option. There is ABSOLUTELY no room in front of the radiator, or beneath the bumper to acommodate one of those big assed things.
All of the above junk is sitting on my "on the one hand" side of my brain.
The other side wants a more conservative, less complex route.
Run E-85, dump all of the rear radiator, water reservoir, front A2W I/C junk, and seal up the Gills on the one side w/ a piece of sheet metal.
E 85 isn't everywhere down here, but it's convenient enough especially w/ the intended purpose of this car to get to.
The benefit to E 85 is that it's high octane, and runs very cool. That'll be of huge benefit across the board as I'm sure that the cooling effect on the engine will not only control I.A.T's, but also the actual coolant temps as well.
The cons are that right now, it's way more expensive than premium and depending on where I drive, I have to be acutely aware of where I have to go to get the tank refilled. The engine requires more fuel when it's drinking E 85, and that means that gas mileage will also suffer, so I'll be stopping more often as well.
Bottom line: It'll cost more to drive it.
As a precursor to all of this, the pump I have isn't capable of moving E85, so I gotta buy a new one. Additionally, I gotta increase the delivery line size up from -6, to -8. I don't know about the return line size requirement as of yet.
Summit will let me return the pump for exchange (even though there is no box......can you imagine being a vendor for these guys?) and I will have to buy the line and fittings to run a -8 feed. Even w/ the return/exchange,..it'll probably be about a 250.00 additional bump, but I may be able to sell the I/C, the rear water reservoir, and the Bosch pump to mitigate that, since none of it has had a drop of water ran through it as of yet in the grand scheme of things, it'll probably be an even trade.
So there you have it.
Keep the complex A2W system and run gasoline.
or dump it, and run E 85.
