Anybody here ever done a compound boost system? Turbo and supercharged. I have a KB 1.5 on my mystic and I'm thinking about an on3 performance turbo system. Instead of selling my blower and getting a new intake and all that I was thinking about just leaving the blower on there. It'd be kinda cool to have. I know I'd probably be better off to just go turbo but I'm not really looking to make 900rwhp on a street car. Let me know what you think.

well if your not looking to make those kind of #s on a street car, then i dont see why you would want to do it.. plus im not sure the 1.5L would handle it all that well... i could be wrong though
From my understanding on all the compound systems I see the blower actually restricts it. Your better off just turbo. I'm just wonderin if anybody has done it. I'm sure you could make 500-600rwhp with a compound system no problem. Instead of pulling the blower, intake, and all that stuff off. Just slap on the turbo kit and see how it goes. It'd be kinda cool to say you have a blower and a turbo haha.
Its not something you see everyday, but Ive noticed a few people on svtp that have that setup. But then again they have the luxery of starting with the eaton ontop of their termi's. If I had to guess I think you would need start with a bigger blower first, then work on the turbo kit. If I had a mod motor this is somthing I would try. Its pretty neto and ya sure their probably easier ways of making big numbers but its a little uniqe but then again not one off, because its been done before.

Compound kits work just fine on C headed cars since those have intercoolers for the stock/kb blowers. On 96-98 cobras the non-intercooled KB might pose a detonation problem if not using Meth. In a compound kit the KB would be supplying the low end power right off the line or in low rpm driving and the turbo would be one supplying the grunt up top with high enough boost, the KB would just be another upper intake at this point...thats whats been explained to me about compound kits
I'm actually running meth and I was thinking wouldnt the intercooler on the turbo kit help out with the heat? Or does the Kenne Bell just create that much heat itself? It sounds like a pretty cool Idea. Maybe run it for a summer then if I dont like it yank out the KB and crank the boost.

^ the KB 1.5 creates alot of heat because it is not intercooled or whatever.. and i just dont think the 1.5 would really be able to handle the performance with the turbos.. Its just not built for big #s... and most compound systems are built for that reason.. to produce the best numbers with the best of both worlds power
Not really, the twin turbo compound system for the 03 cobra's is better off without the blower. Meth is basically like an intercooler. I already have it. I know it's going to be better off with just the turbo but it'd just be kinda cool to have both for a summer and see how it goes. More of a conversation piece than anything haha.Shifty Powers said:

the hellion hellraiser kit is meant to hit 1600HP on the compount system.. do it...
interesting concept. I've heard of it being done...never seen it though. My only thought to this would be, if your adding that much more, its that much more that can break...specially when you start mixing a pretty tough turbo with a 1.5 KB. Not saying it's a bad idea, but sounds like you could run risk of killing your blower. just my .02

I dont really plan on going crazy with it, more of a novelty thing. If I want to get nuts I'll yank the blower and crank the boost. I'd be looking for 500-600rwhp with the compound system at the most. I'm making 415rwhp and 463rwtq with the KB right now.

the KB won't be put under any extra stress with the turbo pushing boost to it. After the turbo starts to out perform the KB then the KB just becomes another upper intake just like any other car not running a compound system. Only thing is that if not running meth the heat from the KB might pose a problem.

I would imagine that the compund boost equation would be tuff to figure out, especially with a roots type blower and heat. The intercooler will cool the air before entering the blower but once the blower compresses the air it heats up again. I would think you would need a heft intercooler to cool the air as much as possible and then meth to cool things again once the air is forced out of the blower. I like the idea and its different. I would make sure you have the funds to build up the 03 shortblock even father than stock and maybe a decent sized fuel cell (not a littel tank) for the meth....just in case.

yeah it drinks the meth up pretty good. I thought about getting the tank or something larger in the trunk. I dont know how much I'm going to drive it since it has 97k on the body. I kinda want to keep the miles lower. I have a 68 camaro project that I'm going to be working on. I would think the intercooler and biggest nozzel for the meth would be ok for a lower boost system. I wonder how it would work with the boost. Would it push out whatever the KB puts out but with more efficiency, or would it put out more than the KB would normally with the turbo pushing it.JDwhite98gt said:
