So if this is true the 10lb (2.75) pulley would produce more boost psi than the 9lb (2.85). Correct?

That's correct on the serpentine side

Thanks. So now that the new OEM tensioner is on and I have no belt slip, I'm gonna put the smaller 10lb pulley back on to see what kind of results I get. Just out of curiosity, what was your set up to reach 16 psi? I am limited to 93 octane so my next step may be methanol Injection. I was also looking into the Z1 intakes but haven't seen that much discussion on them. Any input greatly appreciated as always.

I had the 9lb pulley, 3.47 jackshaft pulley and 3.00 sc pulley. I was just under 17 psi with that set up. I had to run e85 at that psi but since I also ran a wastegate, I could turn the boost down when I ran 91 octane (I ran flex fuel). You don't have access to e85?

You're wondering about the Z1 ported upper and lower intakes? I don't think you're going to gain much with them.

E85 is available about 45 min. away from me so it's not really ideal. 93 Octane is readily available so that's why I am leaning towards the methanol injection. I'm gonna put the 10lb pulley back on now that I'm not getting any belt slip and see how that goes since I was making more boost with that one. I'd like to try and crack 600 whp and I'm almost positive that is not possible on just 93 Octane alone. Just a side note I measured my jackshaft pulley as 3.19 and supercharger pulley as 2.89. I was curious compared to the setup you we're running.

Did you buy your kit used? The stock jackshaft and sc pulley's are 3.20. So, your jackshaft is the stock pulley which makes sense as that's the one you don't want to change if you don't have to. They don't make a 2.89 so your sc pulley would be a 2.85 or 2.95 if measured correctly which means someone had to have changed it at one time. If that's the case, you should be running a 3" sc tensioner pulley instead of the stock 2-1/2" in order to take up the additional belt slack that going with a 2.85 or 2.95 is going to cause.

Yeah I have the same problem with E85, zero local supply. Last time I looked my car runs I think 5 degrees of timing near redline at WOT. Ton of power left on the table if I had access to better fuel but I've at this point accepted my fate lol.

You're lucky you have 93. I know some people here in Cali that don't have access to e85 and have to run 91. I do know someone that has a high hp Z32tt and runs 91 and Boostane. He swears by it.

Close, but some where in the middle. 92 octane here in the PNW.

Let me know how the water/meth injection works out for you JVerge, I'd be interested in perhaps doing something like that down the road as well.

Talk to "Z"en on here, @minized123456 on IG. He runs water/meth on his sc'd z.

I talk to him on occasion, I use his supercharger belt tensioner. Never knew he did water/meth though. Neat.

Makes you wonder how some guys are daily'ing 685whp on 93 at 14psi....

The Kit was purchased new from Topgunz thru RT Tuning. They installed the setup that was sent directly from Aaron. Can you please explain to me which pulley you are calling the sc tensioner pulley? I'm guessing it's the one directly behind the sc. Correct?

Can you detail what pulley setup these guys are running in order to get to those numbers on 93 Octane? Can you also please detail what the pulley setup is supposed be with this kit new? Thanks

Will do. Want to try and get my pulleys set up correctly first. I will be reaching out to "Z"en on IG if needed.

2.95" serp side jackshaft, 3.2" SC side on JS, 3.0" on SC

I should clarify on that 687whp number on the V3-Si. Z1 is the only one who displayed a number like that. Is this daily driven? Did it leave the dyno at that power? Was it straight 93? Im not sure.

I know that Dynosty holds the record for the ACE kit but of course that took E85 and they made 685whp.
