Looks good Josh, I especially like those bumper vent holes. Oh and couldn't you find a bigger intercooler?

A cool air charge is EVERYTHING when it comes to making power.

Hell I was running those 50 trims so far off the "map" that they probably couldn't even see it. I won't be pushing the 76mm turbo THAT far (not sure if the motor can take that much power), but I would like to keep IAT's under 100 degrees at the track.

Now John is even more excessive. His water cooler holds 3 gallons, plus whatever is in the intercooler, plus lines.
That will be controlled via AEM and a temp sensor.

That sure is a fancy windshield washer intercooler that John has! Pretty sweet!!

I thought I was a gauge whore.

Yeah he unpacked them so we can figure out the "order" they are going in the dash (see those holes below it).

The Tach I think is going in the factory location as far as I remember, then it is:

SWP Blower gauge (0-100psi)
SWP Water Temp Gauge
SWP Oil Pressure Gauge
SWP Oil Temp Gauge
SWP Fuel Pressure Gauge

He also has a trans temp gauge, but I think he'll just sell that..or we will use it to monitor something other than trans temp.

I on the other hand have 4 gauges (water temp, boost, oil pressure, afr) and the AEM tells me everything else. John likes gauges and told me I can't add anymore to my car.
I think I should be allowed to catch up

Setup looks good. What sized turbo - 76? Where did you get the mandrel bent aluminum 3" charge piping? What was the big secret?

Is that John's radiator? Looks like it'll have clearance issues, or will be going out the hood. I'm enjoying the work on both cars. I'd like to see them run a few passes. Please inform when you're heading to Rock!

Should prove to be an eventful summer.

The turbo is based off a 76gts. It is rated for over "1100hp" compared to last seasons "940". I'll know what it makes when it makes it. I wanted to be quite as we wanted results and it to be running good for the dyno day (kind of a surprise) but that didn't work out.

Thats johns cooler for his water to air intercooler. It is open at the top so he can toss in ice at the track.

The intercooler piping is stainless

**JET** · 05-09-2007

Do you have a temp probe in the water for John's IC? I would think with that small of transfer area that it would heat up on the street, but I could be wrong.

For the amount of time you spend on boost VS off boost, not really. Engine bay temps will probably be putting more heat in the system, than actually cooling charge air.

Pushit2.0 · 05-10-2007

Pump gas, street driving, low boost... I am going to make a block off plate for the heat exchanger and run as much ice as I can(on race gase and 30+psi), about 1.5 gallons of ice will fit in the top, and use my IAT sensor to turn on the water pump at X air temp. Pump gas will be low boost, 15 or less psi so I do not think temps will be an issue. I will use a coolent temp sensor in the heat exchanger to see what the temps are, then if I get crazy put dry ice in the top with a vent and see what the temps get down to. And the hood will close, I think it will be mounted about 1" lower then it is now. The intercooler is big, the hole system will have about ~4-4.5 gallons, the water pump will draw water from the bottom go threw the IC then dump back in the top.

Crazy setups!! They both look sweet though, and I cant wait to see them out and about.

**scheides** · 05-10-2007

Looks freeking sweet guys! I can't wait to see them up & running!

tim · 05-10-2007

Looks good guys, I cant wait to see the final results.

**JET** · 05-10-2007

With that small of surface area to cool it I thought you might heat soak it over time on the street. Obviously it will work awesome on the track. I am not a pro with air/water, so I was just curious.

MustGoFaster · 05-10-2007

Only time will tell, but I don't think it will be an issue.

Speedfreak · 05-11-2007

Your car looks awesome Swanny, I really like the new setup.

Johns car looks to be coming along nicely as well. Although about the most recent discussion about the intercooler. I would carefully watch the intake air temps on the street when going through multiple gears at full boost. I have a bad feeling it'll heat soak in that situation. At the track.. it'll work. But when on the street, and in boost for some nice long highway pulls(or repeated pulls..), I think it may be an issue.

Matt D. · 05-11-2007

Looks kick ass, guys!

For what it's worth, computer geeks have water cooled computers for a while now. I've read a handful about these systems and once thought about building my own.

One thing is that the more liquid you have in your system the harder it will be to heat up to the same temperature where if you had less liquid being heated by the same amount of heat.

Second, the key is the ambient temperature. Regardless of how much surface area you have on that water cooler you will not get below the ambient temperature. Ice will of course help this, but ice melts.

Same rules apply for air to air intercoolers, but water is a much better conductor than air.

I personally don't see an issue with this setup while street driving and staying out of the boost. They could even install a small fan or two to help move air through the cooler during low speed driving away from the track, but then again I wouldn't expect the air charge to be that much of a concern when not under boost.

Pushit2.0 · 05-11-2007

Air temp will be watched, I plan on doing testing on the dyno with no air flow over the heat exchanger and only the pump running and will steady state (full load at X rpm at X mph) and watch boost/temps then do the same with air flow over the heat exchanger then with ice/dry ice. Pump gas will be low low boost, low timing, and back to back pulls with little/no time for the water to cool down to compansate for the stress of spirited street driving, which I never did a hole lot of and plan to do even less of now with the new laws but if its all out down town for cash, race gas(c-16,vp inport, E98, plus nitrous, what ever works best) so heat will not be an issue then. The fuel system will support the 1600s at full tilt and should flow 92-103 GPM on pump gas pending specific gravity, and 82-87GPM on C-16 pending specific gravity, and 91GPM with ethonal. This is based on 600lbs/hr flow rate with 13.5volts@45psi. If I have to a 5-10 gallon water tank can be added later, or switch to a full front mount heat exchanger, similar to a 04 Cobra.

Nice....
