High boost pulley with C38 looking pretty sexy, is there possibly no way to run that setup on a stock engine?

I probably know the answer but damn that just sounds like a dream lol

Easy, why not? We're doing it with just an upgraded port injector on 92 octane. lol

Might be possible to put in an electronic boost controller. Then you could run a low boost map for pump gas and a high boost map for E85?

Or an extra high boost pulley on the same set up above to get more useable low and mid range?

Just spit balling ideas here.

I didn't think it was possible to run a boost controller with an SC, especially since the boost is completely dependent on what RPM your motor is at.

Well damn lol if you're running it fine on 92, I feel pretty comfortable running it on 93 here then. My goal is 300-330whp, that would be amazing lol.

Well I know there is at least one KW C38 owner using that set up. Maybe it's not possible on a JR kit.

Anyways back to lurking

It absolutely is possible to run boost control on a supercharger. For a centri, you just connect a wastegate to a charge line and run a standard 4-port mac solenoid.

For a roots/twinscrew/standard blower on manifold style - it's even more simple / cheap, but I won't get into that here...

Easy, but not necessary.

^ this.

We're not talking rod shattering power here if tuned right.

And I'm sure since there's not much low end TQ the stock engine should be able to run it reliably.

Edit: So I messaged VitViper about why is boost irrelevant, because I didn't wanna look too much like a dumbass in front of all you guys and this is what he said. I also asked him how much he was making to the wheels. So I thought I'd share this to everyone that's interested in this thread.

"Boost is irrelevant because boost level doesn't break anything (aside from blowing poorly secured couplers off). Power (tq) breaks stuff. The power levels these S/C kits put out won't break anything, even at 14psi.

Boost is irrelevant.

[PandaSPUR]

Very interesting...

Anyone know if Prime Motoring has any experience with tuning JSRC setups? Or can recommend a tuner in the tri-state area for this application? Not getting FI any time soon (summer 2017 earliest), but I'd like to at least get in contact with tuners and ask their opinion.

I am not sure about about that if the people selling the kit recommends you build you motor to run the HBP C38 charger. We are talking almost 400whp with this charger on e85. Something will give sooner than later.

To explain it a little further: Boost is irrelevant because it's only a measure of restriction to flow. If you put a freer flowing exhaust on a supercharged engine it'll likely make more power due to the lower restriction to flow, which will also result in less boost pressure.
