Supercharger for Road Racing

[05yellowgt]

The killerchiller works for short bursts of cool air. Other than that, there's no free constant cold air. The system produces as much or more heat through the condenser than it helps dissipate through the intake. Run constantly on a track day you would end up boiling the radiator, plus the drag on the motor from running the compressor constantly, plus the stress on the compressor from running constantly at high RPM..

Short bursts for drag racing, it's a reasonably good idea. Anything more than that, it won't cut it.

I agree with you on all points. It works for a drag racer who doesn't want to constantly add ice to the IC Res, but there is just too much heat being added to the system for any AC system that would fit under the hood to keep up with.

You have no experience are you clairvoyant?

Yes - Other applications - Engine cooling & water to water heat exchangers for turbo applications. Mine (2) - Acquaintances vehicles several.

One 55gpm pump is more than sufficient if mounted low enough for priming.
(2 pumps are way, way, over kill unless used as a backup)

If you haven't tested it you don't know that.

I haven't tested it, so I don't know either......yet.

 

[Department Of Boost]

Other applications.

Bingo.

Bingo.

Sorry - Just trying to save you $300.00+ & about 6+ LBs. I'll keep my mouth shut from now on.

I’m debating you, not telling you to shut up. Grow a pair Francis.

Annnnnd, you may possibly be saving someone else $300+, but I am doing this testing for Meziere. It isn’t costing me a thing. Granted 6lbs will be 6lbs no matter what. On the one hand I never like adding weight. On the other when you are playing with 800-1000+hp and all the associated hardware that comes with it what’s another 6lbs.

If the additional pump shows a gain I will use it. If it doesn’t I won’t. I have the system set up so I can bypass the extra pump and I am taking water temp readings at 4 different places plus IAT's. I’ll know if it works or not, there is no guessing involved.

Going from 4.5gpm to 20gpm showed a big gain

Going from 20gpm to 55gpm showed a big gain.

At what point do the gains stop? Gotta test to find out.

Shit, Mitch, if you're at that power level, slap a cage in, and come play with us!!

FWIW, this is what it looks like, mid-race, with 800-1000HP:

It is always nice to get things for free - My favorite word by the way.
That is quite a bit of heat – Just curious – Not trying to criticize or create a problem -
How many cubic inches (Frontal square more important) of surface area for the heat exchangers + feedtube surface area?
Total gallons of water including feed tubes?
How many sq. inches of fresh air available?
Plumbing is very important for coolant flow / restrictions.
You can calculate air flow per. estimated average speed/ intake air temp to check the efficiency of your setup & figure out coolant GPM necessary for your application – add 20%. (Meziere should be able to help you)
Check this out & it will save you a lot of time & R&D.
55GPH is a friggin lot for an intercooler / even for most engines.

I have one friend using E-85 in a similar application using no inter-cooling or water injection making 700+ RWPH. I have not personally felt the manifold or checked it’s temp but they tell me it is cooler to the touch than the ambient air – Wipple blown.

I do have a pair not as big & unit not as long as I would like but they do function exceedingly well - even for my age – Quite pleased about that.
Don't want to start a flame war.

To the OP-

If you still want to give it a shot, the Rotrex kit from Forced Air Performance looks like ALOT better option than the ProCharger. More compact, more torque, less heat, easier install. What's not to like?

I guess I'm just going to fall into the third group that keeps working on it until I get it right. What else do we have to do? Remember, it's the journey, not the destination.

Cheers.

E85 has been known to cause frost, yes frost, on the underside of a spider intake on a carbed drag car in 90 degree heat after a pass. It is amazing in its ability to pull heat out of the air charge and combustion chamber.

That car sounds like pure sex! What's the motor setup?

That's great, but Good luck finding e85 when you're not near the farming in the middle of the country.

That's at MMP! My local track. That car kicks ass. Turbo of some sort.

 

[sheizasosay]

SoundguyDave, what hood is that guy got?
I seen a video of Ernesto Rocco driving a turbo car(Agent 47 I think) and the shit was so hot inside the car that when he finished shaking the car down he got out so fast the car was still rolling! That car was putting down major power too. Not trying to one up the maximum car, but, now that I've seen the maximum car running a turbo it looks like that's two major players using turbo on a road race car. So all the "NA only" flag fliers might take a second look at possibilities.

Saweeeeeeeet! I've never met anything with a motor that had too much power.

Ha, making power is the easy part as long as you are running a big enough blower or turbo(s). Keeping it cool and in one piece on the other hand is the trick. It’s a “street car” too. I’ll run a few track days this season with it but the long term plans are for a real race car or renting a “seat” to go racing.

You’re down near Putnam aren’t you? I’ve been telling a friend that we need to get down there this year for a TD. I’ve got a billion laps around there on a bike, some race wins and was flirting with the lap record for a while. I love that track! If we can make it down there maybe you could show me the fast way around?? This car stuff is a completely different puzzle than the bikes.

Because the avg guy probably isn't going to spend the type of money necessary to get to that power level and keep it cool and reliable on track.

I'd hate to sound uneducated and take a guess, but I'd bet the number is astronomical for the avg guy.

 

[sheizasosay]

Fair enough. Not everybody needs 800rwhp either.

I would guess upwards of $150,000 plus keeping it running and putting tires on it. It probably costs $7,00-10,000/weekend to run it when everything is added up. And that is if you don't crash it or blow it up. Your right, that is not playing around money.

Shut your mouth!

Order in the goddamn court!

One more out of you and I'm penalizing you 25rwhp and 50 lbs of ballast!
