you should look at other dyno sheets also- what boost levels and car for those dyno plots?

 

im not trying to make anything out of this. Its all hypothetical and in being so means that lots of testing would have to be done to work out which roots blower would work the best! What rpm and load range the roots supercharger would disenage etc...! I'm just saying that you could do it and get some good low-end torque while still having a meaty mid and upper rpm torque band!

 

Um, just build the motor...

I have a 2.4 that has low end, a GT35r that comes on strong at 3.5k, and revs out to 9400 if it needs to. (and only one turbo to break. lol)

I don't think a SC would make noticeable power or torque below 4k

 

i agree! I don't think its worth it, but it can be done!

 

anything is possible but it would as someone else suggested be for show and tell rather than function-

 

i agree, its definitely not worth it from a money perspective, ease of use and practicality. But it has been done in the past and does give you good down low torque before the larger turbo spools!

Another example was the twincharged system i had with my Supercharged Mini Cooper S. It came with a M45 supercharger and I had a Gt3071 turbo. It had good downlow torque and the turbo was great uptop!

 

centrifugal perhaps not, roots style, I would disagree, that'd come on great nice n early.

I think this actually could be done very well, perhaps not the best money spent as others had said but I think it could make a monster out of the engine. I would worry about the load on the motor at low RPMs though in general. The problem I see with twin-turbo using 2 bands in that you need 3 sets of piping to do it right, thats a lot, not to say its impossible, I think its def. possible but it doesn't make a lot of sense. The s2k IMO has lots of engine bay space. When you come from an ZX twin turbo you'd love to see the space that our cars have.

 

no, it would be roots, not centrifugal...

 

how much time do you spend below 4k?
