- Let the car cool down
- Break loose the 6 hex bolts that secure the pulley onto the supercharger
- Release the tension on the serpentine belt. I usually push down the factory tensioner, and then pull the belt out from around the alternator. You can then release the factory tensioner and the belt will be slack
- Take out all 6 hex bolts from the pulley
- Swap pulleys
- Apply a dab of red locktite to the hex bolts and re-insert them to secure the pulley to the supercharger. Hand tighten loosely.
- Press down on the factory tensioner, and re-install belt. Release tensioner. Verify that the belt is properly routed. *double check belt to make sure it is properly routed
- Torque down the 6 hex bolts to spec.

Note: the belt provides all the support/traction you need to break loose and tighten the bolts attaching the pulley to the supercharger.

On a cold car, I can do this in under 5 minutes total.

No need to swap tune maps, as long as car is running 93+ or custom E85 then?

With the required supporting mods, i.e. bigger injectors, fuel pump and custom tune, can this smaller pulley be run with 91 octane on occasion? Like on road trips where e85 is not available. The custom tune should be able to pull enough timing when on 91 octane? Or do I have to change my driving habits when on 91. No WOT or redline shifts? I think I understand that there is no point in running 91 with the HBP because so much timing has to be pulled but I'm just wondering would it be safe when I'm not near a e85 station?

Any chance of an updated tune from Jackson Racing for this pulley?

(for those of us that have the carb tune and don't live in CA)

Will the motor really survive for a long time running this type of HP and being beat on? The trans? The Diff? Half shafts?

Will the JR oil cooler keep this oil temps under control on track at this HP level?

We have E85 locally, but only 91 and in most of the surrounding states only 91. Suggestions on a tuner who could produce a safe 91 octance tune for hard use?

The power game is such a lustful region to be in.

2. It has so far.

3. 91 is marginal at best. How comfortable do you feel about running 87 octane on a full bolt-on NA setup FA20? Not everybody can be like Austin Powers and have "Danger" as their middle name. :)

1. I know that's why I'm afraid to go down the FI rabbit hole. Something that will hold up to an HPDE weekend and not window the block after 5000 miles is paramount. :) But the extra power would be nice on the track and on the street. I suspect staying with base pulley would be the best idea for me if I decide to go this route.

2. What kind of ambient temps? I just ask because it stays HOT here most of the year. And keeping 375whp cool will be much more difficult than 200whp NA.

3. No sir, I don't like it. I imagine the amount of timing you'd have to pull would skyrocket EGTs. (Since I don't know the voodoo behind the flat torque curve tunes like Emilio used to do for NASA)
