Ok I have an Expo with a turbo swap and almost done, there are only a couple of med size issues. First since there isn't much room for a short route piping on the FMIC, I decided to go with a PTE1000 Liquid to Air IC. Now this is the first time I am doing this so I have a some questions. Hopefully I can get some input.

What's done to the Expo- 2.0 rebuilt with 2 g pistons, big 16g ported with a tial 46mm w/g, DNP manifold, 3" turbo back exhaust, JMF intake manifold, with a NT 63mm TB, COP setup, PTE 660 inj with 6AN lines to and from tank, Walbro 255HP pump, Aeromotive FPR, Keydiver chip, Maft pro running speed density.

Since the motor is a temp setup, the IC is definitely an overkill for the 16g, but future plans are a 2.4 with a FP 3065 or bigger.

What I have already:

Afco aluminum Mustang Cobra heat exchanger (radiator)
JM Fab Overflow can
PTE1000 LTW ic
Johnson 030P7-1 pump

Do I really need to have a heat exchanger to use the LTW ic?
Will the heat exchanger cause cooling issues to radiator?
Will running the pump from the JM overflow or a bigger resevoiur be enough to cool the LTW IC without the heat exhanger?

Thanks guys!

Are you running it as a DD or only on the track?

If it is only a 1/4 mile car you could get away with just running a reservoir filled with ice water. If you ever plan on running it as a DD or even on the highway you need a heat exchanger to bring the water back to ambient temp. The heat exchanger may cause cooling issues; you might have to get more fans and a better radiator. You won't know until you put it in.

This will be a DD since it's a wagon

Hopefully the heat exchanger won't interfere too much with the cooling. Currently just I changed the rad into an all metal, but may upgrade it to a Koyo Evo III rad, if there are cooling issues.

Thanks!

First off, let me get this straight. You plan on using an overflow container as your water reservoir? That won't work, you need like 3-5 gallons of capacity for it to be effective. Get a small fuel cell and use that instead. If you don't want to spend the money, get a 5 gal. Igloo cooler and hack it. Secondly, the heat exchanger shouldn't affect your radiator's efficiency much (less than a FMIC). Without running ice water, your efficiency is gonna come from maintaining as close to ambient as possible temps in the water. With a 5 gal. tank and a Honda Goldwing radiator as a heat exchanger, we never saw over 115F charge temps on a 90F day. This was starting with 80F water, and after a pull it quickly reached ambient. After that, the water stayed just over ambient even after repeated pulls. I'd HIGHLY recommend a gauge for the temp in your water tank and a gauge for the charge temps. This will help alot to ensure that your system is working efficiently. Sounds like a cool project, good luck with it and post some pics!

Thanks Steve,

Saw pics of your car and was going to follow on the gullwing rad. Problem is there is a lack of space that's why I decided to go with the Afco heat exchanger. As far as a reservoir I was more concerned about space issue, after I get the ic, I'll see what I can fit in there

Thanks!

John
BTW I'll get some pics up this weekend.
