PSI blowers

[F N Fast]

Woo hoo, that's fast for a 21' jet. I think the impeller is an agressor stainless AB.

Bigriver, I have a pleasure boat with two PSI's on EFI. At first I had a few problems (mostly with switchable mufflers) but after a trip to GT Performance in Montclair, it starts, idles and runs perfectly, and is very dockable. I may have a few advantages, it has two speed B & M's and is wakeless in our marina. GT doubled my injectors, 8 in the rails and 8 in the hat. Believe it or not, I now get better economy that when I only had 8 large injectors, and no (NO) black on my transom! It took only one tuning day at Elsinore to get it all dialed in with the laptop. Finally, due to low octane fuel at my marina, GT changed pulleys so as not to pull over (x) pounds of boost in case you come up to see how fast she is...ps, the reason for PSI's is that the motors are 598 inches...

Thanks for the info Burt. We are going forward with the PSI for the sake of nothing else but being different. The one in this post was sold out from under us. If you know of one for sale, please pm me.

Alright let me have the inside scoop. Helping a son with a classic Placecraft jet. Thinking of using a PSI to get that classic old fueler look. Are they drivable at low RPM, will they work on a gas motor and where do you find the deal on one? Thanks Bob
PSI's are the shit but they are not the OLD CLASSIC FUELER look if that is what you are really after.

[bigriverdog]

Yeah, your right Dave. I guess what I am looking for is more of the mag case or not polished look with a bag on it. And the boost the PSI will put out.
Burt, I called and spoke with Mike and he checked, but the ones he had are gone. Still looking. Thanks, Bob

Thanks for the info on your boat. It sure looks cool. We ran Pro Eliminator with IHBA in 2001 and remember Dan's boat - it hauled butt.
I'd love to know the overdrive % if you have it and how it compares to boost pressure on that size engine.

The overdrive is 70% for a PSI Blower.

I just sold the PSI back to Dan, and putting a BDS 8-71 back on.
Only reason I did that, is I'm selling the boat and wanted to keep the PSI in the family as it were. Seems that everyone that's called or looked at the boat since I listed it in Jan has no idea what a PSI blower is or why they would want one over a roots blower. I get alot of questions like any idea how much it would cost to polish that thing? HUH???? - whatever.
Anyway, will be moving up a bigger ride soon.

Talk about timing, I just picked one up from a guy in Vegas yesturday. We still need the carburation and other hardware. Did you sell it all to Dan?
