odd idea
I was thinking about it and could you find a way to run a twin turbo set up like this. One turbo hooked to the exaust manifold. charge pipe ran to an intercooler then from the intercooler to a second turbo's exaust manifold to spool the turbos compresor side then run the compressor side to the intake manifold.. just thought it would keep it extreamly cool and would be kind of intresting.. seems like it would take forever to spool but throwing presureized air into the exaust side seems like it would be spinning fast as hell.. just a random thought

Re:odd idea
it might, but i guess i just don't see the benefeit of running the turbos this way....So say you do cool down the first charge, by intercooling, then use that charge to spool your second turbo. The charge temps are cooler, but how long would it take 15 PSI to spool another turbo? If your whole goal is cooler charge temps, why go through all that, when for the same price you can use a bigger intercooler, a water cooled center, and maybe a water injection system?

Re:odd idea
The concept is there.. what leth wants to do is make the turbo as cool as possible so the endothermic reactions of the air becoming dense happens a little bit smoother.
I think spool times and pressure lost will be your biggest enemy.. would be better to just try and condense the charge air more efficiently. You can always get a nice ball bearing water/oil cooled turbo and ice cool/CO2 cool the water charge, and throw some custom oil cooler on the oil charge going into the turbo to try and keep things down.
There are plenty of extra ways you can cheaply gain that lost energy thru heat transfer, if you are serious I can go over them with you (when I'm not on the road in a hotel room answering posts)

Re:odd idea
it's a bad idea, the first turbo, would have to have no wastegate, so that all the exhaust was turning the exhaust wheel, then on the second turbo you would have a waste gate that would bleed pressure. thats simple. but again, it would take forever to spool, and be pointless, cause compressing air creates heat, anytime you compress air you get heat, why do you think some supercharged cars have intercoolers?

Re:odd idea
compressing air alone wouldent create anywhere neer as much heat as if it were connected to the exaust manifold. anyways it was just an idea. and blowers are bolted to the top of your engine for the most part heat displaces into the supercharger the mecanical energy heats up the supercharger and heat rises so anything above the engine is going to get hot and intercoolers in superchargers usualy dont do ----. water injection is way better for supercharged engines. unless you have one of thoes weird *** superchargers with a compressor wheel on the end of a metal rod then you can use a front mount
