Hello,

Just wondering if anyone has ever considered using a 12V Peltier plate or plates to cool the intake after the charger on a draw through supercharged Mini? Just trying to think of ways of improving the current draw through systems/manifolds without turning to injection or blow through. They are small (approx 40 by 40mm) and only a few millimeters thick (although I believe you're supposed to use a heat sink with them). For a single 12V 100W plate the current draw would be 8.33A). I just thought that it may work and wondered if anyone has tried it before?

Cheers,

Jon.

Yes, I've been running the idea around my head for weeks, but only thinking of having it on a standard carb n/a intake where it would cool the air and warm the fuel. I think I decided that it would take 60W to run the chip but it might not improve the efficiency of the engine by at least 60W so it woudln't be worth it. The only way to find out though is to actually do it and then have it rolling road tested before and after.

Water injection seem simple to install run and tune one a very low budget. My home made simple setup has dropped my intake temps a lot.

I used some temp strips on the manifold after the charger and saw a good 20deg drop. Not very scientific but it alaoe showed in the exhaust manifold which now doesn't glow white on the rollers!

peltier elements arent very effective, for 100W electrical input power you'll only get about 30W of cooling, they are great for making small/cool things very cold, but not very good for cooling hot things

Thanks for the replies... Fair play, just an idea, trying to think of ways of reducing the intake temperatures after the supercharger. I know Vmax make a charge cooler but to be honest, I don't think it is cooling the correct place. The charger itself doesn't get that hot, you could run the engine for a couple hours and it is just to say warm, it's the intake after the charger that gets hot, just not too much in the way of space to do much about it...

I've always been a bit sceptical about the idea of water injection, not that I know too much about it, how do you control the amount of water injected?

Can you heat wrap a mildsteel Maniflow LCB? I've read somewhere it can lead to the manifold cracking... Any other thoughts on how the intake could be cooled?

Cheers,

Jon.

The water injection on mine is very wimple but if you get a proper kit you can control the system very weel. Mine is just a .70 jet that is tapped into the manifold just before the charger whcich is switched on at 5psi of boost via the megajolt.... simples.
