Turbo/SC hybrid

So heres me new idea after my supercharger equipment upgrade. Im gonna be putting in an intercooler, 11 or 12 psi pulley, 550 injectors, walbro pump, prob an emanage ultimate and z32 maf (might have forgotten something). After all this stuff is in and working well, i was thinking of getting a 9b, like the kind of stock little turbos in the VR4's casue there cheap as hell, like $150, and would spool quick as hell. Get a custom downpipe made up, an oil and coolant line and boom, thats basically it. Ive heard of this setup before, the only thing ive gotta reasearch more is the boost of the opposing chargers, kinda fighting themselves or something, cause the turbo would spool instantly and then prob die off while the sc was comming up to speed. Gotta worry about turbo stall and stuff like that, but i know its been done and it seems to me like it would be a great combo. Let me know what you guys think. Thanks

Seems pretty ridiculous to me. It's going to be WAYY more work than just doing a regular turbo kit with a non Fisher Price sized turbo, and you are going to end up with less power than you would get from a regular turbo kit...

It takes a helluvalot more than a downpipe and an oil line to plumb a turbo.

Usually it's a screw-type supercharger being used til the turbo spools up, are you suggesting a small turbo to wait til a centrifugal supercharger begins making more power? Even a 9B isn't going to have instant spool, so it seems like the effects would be near pointless.

Not to bash or anything, but it seems especially absurd on a FWD street car.

9b would be spooled by around 2500rpms. I myself think this is a pretty good idea, seems how these combos have been used to set land speed records. It makes perfect sense, who wouldnt want to increase their powerband?

And yes, FWD sucks...but they can still run some pretty damn good numbers.

Ok, but is a single 9B that won't even spool til 2500 (which by then I'd think the supercharger would have started doing it's thing) be worth all the associated extra trouble you'd go through, added heat, added weight, etc.?

I know the benefits, I just don't think the benefits outweigh the troubles.

Interesting setup on that forum. Currently my sc doesnt really get goin till about 4.5 grand so this is my reason for looking at this possiblity. I will of course do my research, see whether it is feasible to run the turbo for low end boost then sc for high, and if not, i wont do it, but if it ends up looking fairly simple and useful, i might just attack it. However, if im happy with the setup when i get 11 or 12 psi and all the extra stuff, i prob wont bother and continue with my carbon fiber projects.

interesting idea but way too much overkill, what are you gonna do when something goes wrong. troubleshooting is a biatch with just a sc or turbo imagine both of them. our cars dont boost till 3500 rpm so it would be nice if it worked till then but a much cheaper route since you have s/c already would be nitrous in my opinion. thats how mine is set up and there is no lag ever and i dont have to use it unless im racing.

think about it how often does the lag effect you? only when you wanna pull on someone or the track. for 600 bucks you can still have a safe reliable car without added problems from a turbo and it works pretty darn well if you ask me. having a turbo/sc car would be impressive though,lol.

Just use a 50-shot if you want some ***** on the low end with your SC.

WAYYYYY easier and likely more effective than your hybrid setup.
