I don't know much about FI, maybe somebody out there with more experience could chime in as to how temp change in the intake charge relates to hp. This would give me better idea of how much cooling need to take place to make this worth while.
I dont know how feasible this is, but it would be interesting to give it a try.</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">for about every 10* drop in IAT temperature you will see an increase of about 1% in horsepower

Re: Blowing nitrous across Ati intercoolers??? Peltier plates? Lol..been there done that about a year and a half ago. Have a small working prototype in my garage. There are three small problems with those.
1) a 1" x 1" peltier plate can draw over 5 amps. So covering an intercooler could be in the 100s of amps range.
2) it is VERY inefficient. The heat generated is ungodly compared to the temp drop on the cool side.
3) does not like lots of CFM...the cooling effect is easily overtaken. You can get a temp differential of 50-100 degrees but flow some air over it and your talking a ten degree drop. Not much.
Now...im not saying it cant work. But it will take a serious design effort to come up with something efficient enough to make gains on something like an intercooler made for huge CFM on V8 motors. A good ducting system for heat dissipation on the hot side of the pelt plate will be half the battle. Not too hard with fwd airspeed but at a stop youll need a fan. <img border="0" alt="[jester]" title="" src="graemlins/gr_jest.gif" />

Re: Blowing nitrous across Ati intercoolers??? Now only if you could combine a thermoelectricaly cooled intercooler with an electric supercharger...that would make for a potent combo. Course, you'd only need an electrical generator from a Boeing 767 to supply the power.
I actually whipped out the Heat Transfer textbook for this one. If you have a 50 lb/min mass flow, and you want to cool it 40 degrees (and these are representative of an FI LS1), then you'd need 7,600 watts worth of heat transfer within the intercoolers. Now the intercooler itself is about 80% efficient so your up to about 10,000 watts. In BTU's its over 100,000. Basically if you can get two 50,000+ BTU thermoelectric coolers, then your all set. Being inefficient, it would probably draw 30,000 watts from the car. How much can your alternator produce? Then what would you do with all the heat generated from the hot side?
The only way to power a supercharger is with the crank itself. The only way to cool the charge is with the air that flows past the car. Anything else is too little for too short a time.

Re: Blowing nitrous across Ati intercoolers??? Peltier rock <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> . The amps a more like in the mid to high 20s though. I have a 156watt peltier and it needs 14volts and 23amps to run at its best. Needless to say its not runing at its best.

Re: Blowing nitrous across Ati intercoolers??? Hmmm,... custom cut dry ice block mounted to intercooler. One block... one run. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
