Actualy the faster I go the better it feels. (thats Scary)
After conversing with others and the minimal cost I decided
on the swept backs.
The drives are 3.5 inces above the bottom with no spacers.




Far as the PSI,s Dont know the verdict is still out.
I hope I am doing the right thing the Mooneyhams
and engine combo ran flawless . I may wanna have my head examined.
I have been told by Roger at PSI that they need all the fuel in the world and will run hot below 3000.
I was waiting patiently for the Whipples but, after talking
directly to the engine developer who tested the new 5.0s
He said They are great for around 1300 after that he would stick with the PSI,s. No names being mentioned.



More props to try next season.

Looks like things are coming along nicely, can't wait to see the final results.

I'm running BDS 1471's. At 8 pounds my motors are making 1157hp. I'm not interested in more hp, I just love the look of the PSI's.
I have a 2000 40' and over 130 it definatly got a little loose with the old style lowers. I still haven't run any positve trim on it but I'm looking forward to the new lowers. My drives are 5.5 from the bottom.
This summer I am also going to try some 5 blades. I have a set of 17x34 4 blades that I am going to send back to BBlades for a little tweaking but I still want some 5 blades
You should bring that bad boy out to Desert Storm this next April. It's a great time. I look forward to your updates!

Michael,
Please let me know how the 5.0 whipples work out.
I really wanted to try them. just no patience.
CP Performance actualy has a part number for them in
there catolog.

Yeah the PSI,s are wild looking lets see if they perform
like they look.
When measuring your drives I take it you are running a straight edge off the bottom and going to prop centerline.

Are you running spacers?

Lets see some pictures!

I will. Hopefully it will be soon. The motors are down at precision marine right now and Dustin told Mark to expect them the second week in Dec. They are all going to Orlando for the PRI show so hopefully I will find out something then.
Good luck with the PSI's, they look great. Your set up looks similiar to what I was up against with the quad whipples. I was able to do some tweaking and used a longer shaft between the carbs.

Gerry whos inter coolers are you going to run if any?
Looks great hope the PSI works out!!!Also are you going to keep both sets of props?

I'll be interested to see how the 5.5 compares.I,ll be doing a little spying at Marks.

No spacers. Hopefully the new lowers will be the setup. As soon as it gets done with paint I will post some pics. Don't forget about the winshield, keep us informed.

Keith, I have been using these Richard lee coolers
with the cupranicle cores. Less prone to core meltage.
The big whipple coolers (MOAC) may be a better choice.
but the lees are paid for.

My intentions is to stay within the pump gas region.

I am upgrading to multistage pumps as to do
what I have never done before and force feed the
intercooler with a dedicated stage.
I usually tap it off the sea strainer so it gets water only under
speed. My thought is the PSI,s need that xtra cooling at
idle and low speeds.

As props go. I will try both sets and most likely keep one.
I would also like something smaller in the 32 33 range. Good for some "Smack down daddy punch"!

FREEDOM US1

Glad your having fun with your skater. I have some 5 blade 33s you can try. Can I try your 37.5s? I have been wanting to try a prop that size for a long time. My 33s are good for 130mph at 6100rpm.
