Awesome! I was looking at the Fragola 6000 series as well as the Vibrant stuff. Good feedback. Helps to know what others like and/or are using.

I used Fragola PTFE line and Racetronix PTFE AN fittings and it all worked fine together.

While I'm waiting for the PI kit to ship... let's talk boost and pulleys.
In order to raise average boost, as a side effect, I'll be raising peak boost too. What's a safe average and peak boost for SBE? If I wanted to target 10 psi average, I'm thinking that might be around 12 psi peak. I'm also thinking I'll be in the neighborhood of a 3.7" pulley, and can play with shift points to tweak to something safe.

I think 10 to 12 boost is pretty safe especially since you'll be running E85. I don't know anything about the pulley sizes for PC.

after that, you can play around with the procharger rpm calculator found here: https://www.procharger.com/supercharger-calculators/ additional note: the general rule of thumb is that every 0.1 change in pulley size on the upper will equal ~ 1 psi. that is again a rule of thumb. I ran a 3.9 upper and 8.25 lower and had ~10 psi in a fairly free flowing FBO engine. Results are in signature.

8.25 pulley and 3.7 upper on forged, cam, ported heads was making 13.5 psi in summer and 15 psi in sub 60* temps at 6800 rpm, if I take it to 7-7200 I gain almost 1.25 psi. |

Great info! Looks like I have the 7.65 lower, so seems to me like the 3.7" is the right choice for what I want.

I would honestly start with putting an ATI underwrite pulley on, and a 8.25 lower. Increasing pulley size on either upper or lower will increase your contact patch, and have less of a chance for belt slip. Naturally going down in size increases your risk of belt slip. Typically belts start to slip in the 3.5- 3.7 range. Also you get to have better dampening and the underwrite pulley frees up some cheap horsepower as well.
