Status: offline 		On typical nitro-powered rc's the pressure line running from the tuned pipe to the fuel tank is replaced by a pressure line from the turbo and a check valve in the pressure line regulates pressure in the tank. A custom setup would have to be developed for your application.

what are your thoughts on cooling for the turbo? are you thinking of making a intercooler?

Status: offline 		The machining cost involved with creating a separate mini-intercooler to include in the kit would be impracticle at this scale, but a simple alternative that would work just as effectively would be to machine cooling fins into the turbo housing itself. I doubt it will become part of the basic kit, but it might become a design feature in a 'race-only' version for competition use that would incorpirate sevral other design ideas I wanted to put into the basic design but couldn't for economy purposes.

i just thought that it would be pretty bad ass to have an actual working fmic.

Status: offline 		RB Innovations makes a fan for a heat exchanger cooling head.you might be able to get it to blow air on the turbo somehow. they also have nitrous you could inject that into the turbo to cool the air down and the nitrous will give it more power .http://www.rbinnovations.com/catalog/product_info.php/cPath/23/products_id/70?osCsid=d0c04fa08ca539384d890b4c2237b297

By the way, does ANYONE have suggestions on how to strengthen my turbine castings?

A few years ago I read about ceramic turbo rotors, I think Ford was experimenting with them. They where cheap to cast, and took very hi temps well, you might want to check it out.

Status: offline 		Thanks for the input everyone, it's always good to hear new ideas:

'brother dust', I don't think those cpu radiators are air tight, but they would make excellent radiators for the engine itself and at $45 they're in the right price range. With a few mods I bet I could get them to hold some boost, thanks for the link, I'm going to get one and see what I can do to it.

'bobdole', I don't plan to include an external cooling system in the turbo kit because it seems to stay within 20 degrees of the engine's temp even after running for sevral hours on end. I'm not a big fan of rb's products, but the cooling fan they're selling looks like a pretty good idea. The only concern I have is that it's always running and if the engine becomes too cool the internal clearances would change and thus potentially damage the engine, but if it were hooked it up to a thermometer programmed to turn the fan on when the engine began to overheat you could run it all day without having to watch the temp.

'soarrich', I've already solved the turbine's strength problems by using 'consumable-mold' castings instead of die casting. Cons. mold casting opened up my choice of metals enough that I was able to cast them out of brass, iorn or aircraft-grade aluminum which eliminated the problem of advanced bearing-land wear on the turbine after extensive use. The problem with ceramic turbines is that they're extremely brittle compared to metal turbines and they have poor heat dissipation charachteristics, which is why they're rarely used in production vehicles. After I test the turbines made of iorn and brass for durability I'll decide which material will offer the best compromise between strength and wear characteristics to use in my turbos.
