Battle of the Pulley! (Removal) - Honda Prelude Forum

WBB6 · 03-12-2002, 05:32 PM

Well since my car is parked right now for the winter and since I ordered my 9 PSI pulley today, I decided to go an try to remove my 6 PSI pulley...

After reading about "Schwett's" battle, I thought that it would be a struggle that would last for hours, so first I removed the nut that was holding the pulley in place, then I sprayed some "Liquid Wrench"...and then I used a flat head screw driver to pry it off, and to my amazment, it started to move, and 2 mins later it was off...I was like, man that was EASY!!! There was No damage to the 6 PSI pulley, not even a scratch...

now I can't wait to get the 9 PSI pulley and install it!!!

Hahahaha. Don't let schwett see this post.

Btw, what are you doing as far as fuel upgrades go?

Toretto · 03-12-2002, 07:13 PM

Thats cool. Its probably one of those problems people will randomly have. Yea, what are you doing as far as fuel goes? Is it safe to run 9psi on a stock engine? Also, would the water injection cooler help enough to make it safe? Want to know, cause if it is, I may just start out with the 9psi pulley right from the get go.

As far as Fuel upgrades goes, I was talking to my mechanic that tunes/works on my car, and he previously had a JDM H22a in his Civic running on pump gas 440whp...and he fully built that motor himself so I usually don't question his judgement...
anyways he told me that our factory injectors are good up to ~320whp, and the stock motor is good up to 10 PSI - 11 PSI if you like to live dangerously, that is why the FMAX Turbo kit runs only ~7-8 PSI, also if you notice that the FMAX Turbo Kit utilizes your factory injectors!

For changing the fuel pressure, I will be using my V-AFC for that...recently when we fine tuned my JRSC we noticed that my car was running VERY RICH, so we used the V-AFC to "lean" things out...so I should be safe with the 9 PSI pulley!

Lets just hope so eh? haha

What are you doing about keeping things cool? I get 93octane around here, which isnt bad, but detonation on an engine that has a CR of 10:1, lets just say its bad. I am considering putting the 9psi pulley on right from the get go, because I have heard you need to take the SC off inorder to get it on. Although I would want to have a header and exhaust installed before that, so I guess we will wait and see.

With factory size injectors, you will most likely run very, very, lean on a 9 psi pulley, unless you really want to see what 150 psi of fuel pressure is like. One of the JRSC guys on this board was running lean with the stock JRSC pulley.

F-Max uses 2 additional 440 cc injectors along with the stock injectors.

IC, I was expriencing very rich conditions with my stock JRSC pulley, that is why I am kinda assuming/hoping that I would be ok with the 9 PSI, well what I am going to do is try it first with a Lamba Meter to get "accurate" readings, if I experience any lean conditions, I will STOP, and correct it with the proper modifications.

As for "Toretto" you do not need to take off the supercharger to install the 9 PSI pulley, "Schwett's" case I think was an isolated case!

I will personally guarantee that you will run very lean with the 9psi pulley.

FMax (like inlinefour mentioned) uses the additional 440cc injectors to aid in fuel delivery. Guess how the Drag kits do it? They use stock injectors + HIGH fuel pressures.

The JRSC kit does the same as the drag kit. At WOT your pressures on a base 6psi kit are in the low 100's. That's pretty damn high for
- the injectors
- the fuel lines
- the fuel pump

If you go to the 9psi pulley, the pressure you will need out of the stock injectors won't cut it.
A) The Walbro won't keep up.
B) The injectors will most probably reach a point where increasing fuel doesn't affect fuel delivery.

Finally, and more importantly, schwett was NOT an isolated lean case. Off the top of my head, here's just a few members who've reported running lean on the base kit, REGARDLESS of fuel pressure:
- schwett
- myself
- LuderSH
- Prelude23h
- Another owner (who was told by me from Jim Helbing)
- A fellow JRSC luder in Tampa.

And these are just the owner's that I've heard about. This doesn't include the other potential 60+ kits that were sold within the first few months of the kit's existence (whose owners obviously don't frequent any webboards).

But if you think you're car can take it, more power to ya.
I wish you the best of luck!

Whoops! You get what I mean, though.
Plus it's nice to have made a list like that now.

jeez. you suck!

So does that mean you can't boost any higher than 8psi on a FMAX kit? Or is that just the lowest boost pressure setting?

No, that is the setting that the kit is suggested to run at...I'm sure you could run higher boost, but you would need to upgrade a few things...

95PRELUDEVTEC · 03-29-2002, 02:04 PM

well fmax said you can run up to 13psi if you run with the irdeal head gasket....but i wouldn't may 10psi at the track and 7-8psi daily
