Intercooler/Dry Ice Idea

[87grandnational]

Well, I dont really know how many people have tried this but I thought it would be worth a Try.

Im going to take a 3" Peice of Pipe, cut, bend, cut, bend, cut, weld, weld, weld... ect.. From the turbo, To the MAF, down were the stock airbox is (which will be removed). loop up to an intercooler sitting in the grille. Well, true the intercooler will have cold outside air blowing into it.. but Im going to make it a Dry Ice resivior (spelling). Since dry ice doesnt melt. I was also going to Install a Alky injection kit somewere up twards the turbo on the intake side, and either shoot Alky, or Nitrous. Which ever one is the coldest. I think that I might be able to get the intake temps down to around 15 degrees before it hits the turbo, so that it will heat up to around 70-80 when fully compressed.

With this set-up I should be able to run about 25psi. Forget about the fuel and tuning and all that, I know that comes into play. But theroreticly thats what I SHOULD be able to run.

So With that setup, 3.5" Down pipe and 3" exhaust.

If the turbo was,.. I guess.. uh.. 'supportive' enough, it would crank out 450rwhp 525lbs/tq

Oh well, mabey I could hit 550-600rwhp with a TE63 and P&P Heads and bored .030 over.

What do you guys think?

That sounds like an awful lot of work! Seriously though, It could get pretty complex. What were you thinking of for a reservoir configuration? That type of setup would need to be refilled periodically, as the dry ice does just turn directly into CO2 instead of melting. Sorta reminds me of how strictly drag setups ice the intercooler, but they do take it out before the run, so that outside air can still get to the intercooler. I guess you can buy intercooler sprayers that spray CO2 onto the outside, maybe that would be a simpler/cheaper alternative for what you are trying to achieve with the dry ice?

Just to get a better picture of what you are saying, do you want to do all of this cooling before the air gets drawn into the compressor side of the turbo, like a sort of precooler, or after the turbo as an aftercooler/intercooler? Alky is usually shot after the turbo at the intake adapter, not sure if it's a good idea to shoot alky into the compressor turbine.

Just trying to get a better picture of what you mean. Interesting idea though.

Thanks, just trying to figure something out before i decide to go to an intercooled set-up.

yeah im trying to make a precooler setup.

If i can get the intake charge below 0. then I dont see why it wouldnt work

I have been kicking around the idea of some sort of "pre" cooler as well. The real problem that I see is figuring out a way to cool a large enough volume of air fast enough to actuallly make a real difference.
