what parts are needed to increase boost for Stillen Supercharger

nic370

How much power are you planning to make ?
That would tend to determine what upgrades are needed

good point and I was just thinking about adding that. Would be happy to be around 500-550. Will be running 91 octane unless you guys recommend other wise.

13 psi is about the max you'll be able to run on 91 octane. With the 9lb pulley and a 2.85 sc pulley, my car made 12.86 psi and 586whp on e85 with the same upgrades that you have. I can't remember what my 91 octane numbers were but was probably a little over 500.

I would go flex fuel. 91 and e85.

You list a single walbro 520 but then you show a CJM twin pump. Why would you have a twin pump set up with a single pump?

I got the twin fuel pump assembly for a pretty good price. Also when I took out my stock pump assembly the rods were already broken. So instead of buying a new nissan oem assembly I just bought the twin assembly for a good price.

And when you want to go for big power (and you will), you'll need twin pumps.

After reading spooler's thread I dont think that will be the case. I dont feel like replacing the block lol.

DUSHER

as far as flex fuel/e85 would this be all I would need https://www.specialtyz.com/370z-g37/...-fuel-kit.html ? Also could you point me to a website where I could buy those pulleys at?

"Z"en

The kit shown seems to be for NA. Seb knows what kit suits you. There are options out there.

For flex fuel you will need the Zeitronix ECA-2. I'll find the links for the pulleys.

Another option for flex, especially if you’re getting a gauge of some kind is an ECB-1. With that setup, I did not need any additional electronics, like the ECA-2.

https://www.innovatemotorsports.com/products/ecb1.php

I would just like to mention to all, that with Flex fuel , the electronics for whatever you use to monitor ethanol, need to be powered DURING cranking, when most accessories shut off. So my gauge for example, which tells the ECU how much E% I have, is powered when the fuel pump turns on.
