28 single speeds
 

I thought I would ask the hard core a question. What would it take to move a full pleasure single 28' to the upper 90 mph. Yes I know alot of HP , but I'm sure one of you guys knows the combo.
Thanks

$50,000 .....900 HP AND A #6 DRIVE :eek:

I`ll tell you in a few weeks with my new blower motor and a 31 H6 Hydromotive fully labbed by Throttle-Up.......

Killer!! can't wait to hear how it runs.

Re: 28 single speeds
 

I agree with Bruce 900hp and a Six. Why would you want to got that fast in a 28ft boat? Upper 90's? Brian Stublefield (BSTUBBS) should know exactly.

Danger, I didn't think I would. I really get off on running the boat fast. It's hard to explain. It would be nice to run 75 and not be twisting the engine too hard. The last time I went out I had several boats do u-turns when they saw me and wanted to run me down. It seemed like everybody wanted some :D

600 hp will get you 75 mph 650hp will get you 80

Re: 28 single speeds
 

Nice!!!
You got any new pics of the boat?
Have you done anything to it?

Re: 28 single speeds
 

Bruce, I have Jerry's old 28. I'm only seeing 74mph. I was thinking it had around 625hp.26 4 blade.

Hey Storm, I pulled the stickers, numbers, etc. off . I modified the trailer( electric over hydrolic) and shorted the tounge about 30" now the rig fits it my garage. Other that that I've been running the mess out of it and absolutly loving every minute of it. Everybody who has one knows what I'm talk'n bout!! This has been a dream come true for me.
I promise I will post some pics of the up grades and other goodies.

Re: 28 single speeds
 

what RPM are you turning the 26p? Jerry's motor is prob more like 600. I dont know if it was ever dynoed.

Re: 28 single speeds
 

I think your right. ( Depending on how its trimmed) 5500-5800
74mph is with less than 1/2 tank and a passenger or two

Re: 28 single speeds
 

hmmm..if you can turn a 26 at 5800, you should be running around 77 78
you might need a 2" shorty

Re: 28 single speeds
 

maybe i just need a new gps?

Re: 28 single speeds
 

Two years ago with Tim G. and Pantera24 Angel on the boat I did 94 mph with my 540 blower motor at around 5800 rpms and a 31 Bravo. It takes alot of ponies to move the 28 into the 90`s. That was with a 871 blower with only 7 lbs. of boost. Now the new motor is a 582 ci 1471 with intercooler and 1050`s 410 cfm Dart super ported heads with 10 pounds of boost should bring me close to 100. Bruce is going to drive it :D :D Man I love this topic SPEED.......

Re: 28 single speeds
 

Might even need more than 900hp.

Here's an old thread with 900hp and a 3A

Thanks Griff, Well I now a guy down the road that has a blown 540 with a super chiller I think it's a 671 blower. It comes with carbs to oil pan with electronics and race mounts and a few other things. He wants 12k. I think he said it was detuned@700HP with only 4-5 psi for boost.
I wish my xz drive would handle it.

I think my wife would poison my food if I started to get that glazed look in my eye for more power.
:eek:

Re: 28 single speeds
 

Speeds are never enough, their is always someone faster out their, dont hesitate to jump all over that blower motor or your life will never be the same.
