What all is done to that thing?

 

Good Lord, I don't even know where to start. I've been working on the car for almost 5 years now piece at a time.

The main things:

- Engine ported and heavily modified (1987 S4 core)
- 60-1 turbocharger
- custom air-to-water intercooler
- Haltech E6K EFI system with re-done fuel system

I won't list all the things done as it's about 5 pages worth.

I was about to say you must have some major work done to be hitting those times in the 1/8th

 

Yeah. I've done quite a bit of work to it. Alot of it is considered 'unorthodox' compared to what alot of people do, especially here on these forums. In the 5 years I've had it, I've learned how to modify cars and what not. It's the car I learned on. Alot of what I've learned steers away from what most people do as I tend to focus more on things that are technically-centered instead of what I can bolt-on to make power. I've done alot of experiments; some of which have been failures but were good learning steps on how to do things right.

man, that car is a total sleeper. Insanly fast.

 

Did you put that 420 hp down through the stock IC?

 

As a matter of fact, I did, Felix. The stock '88 core (actually Trey Cobb's old one off his 10th if you guys remember him) was converted to an air to water intercooler system 3 and a half years ago. I used that core, jacketted up to hold water, in conjunction w/ a Rule bilge pump and a custom-made tank that held about 5 gallons of water. Worked like a champ.

It kind of blows the theory away about the IC being this big, huge restriction when, infact, it's not.

Thats good to hear. I'm trying to get 300 rwhp from mine, but I'm about broke. So no FMIC for me, and from the looks of it I don't really need one anyway.

 

Are you Brian D. Cain from the old TeamFC3S mailing list?

 

Last time I checked, yep. Also known as BDC with some of my friends.

That's a good goal to reach and it's definitely do-able. The problem w/ the stock intercooler, however, is two-fold:

- One, it's got 100% reliance on questionable hood (and scoop) aerodynamics. Some of the Japanese say that alot of the ram air bounced off about mid-way past the front bumper at speeds over 60mph, rendering the core ineffective
- Two, the location of the core (as I was suffering from as well) is in a bad spot considering the effects of heat soaking. The engine heats the surrounding air and that hair rises and steadily heats the core up over time, especially when the vehicle has been sitting for a sustained amount of time. The effect it had on mine was coming back to water temperatures (that were still in the core that hadn't drained back into the tank) of over 100F degrees. Using a radiator w/ an A2W setup can solve this but it takes some time to cool that mass of water back down.

I've thought about sticking a small fan on top of the IC to help with the airflow.

The only time heat soak will be of a major concern to me is at the strip, since I don't race (or drive hard, for that matter) on the street. I suppose I could lay a bag of ice on the IC while I'm in the staging lanes.

I wonder if I could insulate the shield that is under the IC with something to help keep the heat soak down a bit, or if that would be a waste of time.

 

Holy crap! You were a legend on the list, back when I was a newbie, good to see you finally made it to the board. Your TII is amazing!

We've got a lot of the guru's from the old list, Ted is around here sometimes too.

 

I even started a thread a week ago "Where's BDC?"

I was pointed to the yahoo RXTech group. I subscribed and can read all the emails but can't seem to post. Glad to see you are still around. You wouldn't remember me, i used to drive a 90 GX model don't even remember my old user name on the list... but it's good to know you are still around doing crazy things with 7's.

 

My buddy and I were looking at ways to do the same thing a long time ago, too. The idea of the pusher fan atop the core was mentioned, too. The only problem with it is finding a fan that small that can move a sufficient amount of air to make it advantageous. Another thing we tried was constructing a water sprayer atop the core. My friend's brother, Ethan Fisher, had success with it as I did as well. We'd run water through tubes that shot on the core as we were running. It was like running a mini air-to-water unit.

The bag of ice trick only works for a VERY short amount of time. As a test, I ran a stock IC w/ a huge bag of ice dumped on top of it to see what it'd do. By the end of 3rd gear on an 8th mi run (heck I didn't even make it to the end of the gear to be honest) the intake air temps were eclipsing 275F degrees. Not a good thing.
