Looking for new blowers, any opinions?
 

I'm starting to do some work on a winter project. I'm trying to find the best way to go with Blowers. I know a lot of guys are going to PSI's which are an option for the, the only problem is they make the engine so tall you need monster scoops. I know there were some cool looking ones at the boat show but really don't want to be a Guinea pig again. If anyone has had good success with something that makes big power please let me know. I want unbiased opinions. I know some of you motor guys try everything!

How about the new 5.0L Whipples? I know Gary Taylor has a done a few motors with them recently with really good success.

Whipples and if you cant get them try and get Whipples:grinser010::drink:

The PSI looks so cool along with the power as well.

What about something like this? Low profile and Tomcat tested it at Sterling at something like 1800 hp. http://www.rtechperformance.com/biggun.html

I agree with Patriyacht. The R-tech stuff is the real deal. Got a buddy of mine that was part of the original prototype and the boat/motor is amazing

I have talked to Tom at R-tech. The guy knows his stuff. He was at the shoot out in 2004..

The new Whipple is the way to go.

Thank you for the responses. I saw R Tech at a show. I will call them today. The new Whipple may be an option. Thank you.

Have you looked into turbos, they are capable of making incredible horsepower

People have been trying gor 30 years to make them work in offshore applications and the "lag" when throttling the boat makes it impossible to run in rough water. I know they are trying to perfect them but I haven't seen any boats with them. Last year I was ready to write a check for a set until an unrelated incident happened with the person that built them and it completley turned me off.

I thought that Chief motors have had good success with them

PSI will make any amount of boost 20-30 40 lbs.

You can put your hand on the side of it.
Try that with the other toys.


Live with the height run the Whipple MOAC.
Mill the sh@t out of the intake and hang on.

They have tried other blowers but they all seem to go back to
the PSI.

I think you know all this anyway.
Just get over the height deal and hold on Bro!

Check with Steve at progressive, he had told me about the new turbo that the power is right there when you need it.

Don't know much about superschargin.

Nobody mentions Vortech or procharger. They will take care of the height problem just fine.

I've heard the same thing. I like Tommy's stuff. He's right down the street from you as well Gino!

No need for anything else. Just set the pulleys on the PSI's for whatever amount of power you want!

And if you could make boost at 1,500 rpm's then would you be interested in Turbo's ??

1,500 Hp pretty easy,.........very low compression.........

With these engines there is NO turbo lag..........You won't beleive it unless you ride in it.
If you hurry you'll still have time for a ride before winter sets in.

Quieter than a stock Black Engine and it has no mufflers.
No CAM lope either ;-)

I'm not aware of any issues on the Chief turbos. They look great, run great and you couldn't find a better guy to do business with.

For the power, reliability and money, you can't beat the 5L Whipple. Use the rear entry axial efi blower and you won't be much taller than a NA motor with a carb. They can make all the power you want or need. Turbos have come a long way, but they still have a way to go. Cost has also come down considerably, but they still have a way to go, IMO.
I'm doing a set of Whipples now and I can't say enough good things about them. These are hydraulic rollers that make 1400 hp at 6100 rpm on 100 octane and 1200 at 6100 on 93 octane.
Gino, give me a shout if I can help you or answer any questions you may have. Thanks, Eddie.

They certainly made some sick power, but it was also 22psi of boost! Its very, very hard to have a reliable engine package on gasoline with 22psi. I think power would be closer to mid 1500 to low 1600 with 15psi which is still great. Turbo's at this point would be near the 2000hp range (22psi) but turbo lag is extremely difficult to get around as well as low end torque, and lets face it, some of these big boats with big props, high gears need lots of torque down low.

Hey BIG Daddy do the PSI and move on :ernaehrung004::ernaehrung004: check your mailbox :drink:

Go with whipple.

The product is superior and the customer service is outstanding.
Dustin goes above an beyond.

We run an honest 14 to 16lbs of boost on 93 pump gas and methanol injection with our 565 CI ,1471 high helix blowers ,hydraulic rollers, spin 6500rpms every time out and only need 30 degrees of lead to attain well over 1400hp on pump gas with this set up.
We now have 200+ hrs and currently leek down at 9% cold.

We haven't tested it yet but I would think that the new Whipple spun to the moon on meth would be lethal as hell.
Just be sure to have a few spare #6 drives in stock.
Good Luck with your project!

Just be sure to have a few spare #6 drives in stock.:eek:
Glen your a funny funny guy , more B@@ST :ernaehrung004::ernaehrung004:

Its stating to get old we just blew our Starboard drysump 6 on Tuesday.

We are pulling it later today, thats 5 drives in two seasons.

The down side to our sick acceleration rush!

thats 5 drives in two seasons:cool: Phuch
I do believe i will be able to pass that # :ernaehrung004:
I'll call rudy and give him some chit

Gino sorry for the hijack BIG Daddy

We Run Whipple R980's Which Are A Big Screw Blower Built For Alcohol Drag Cars. We Picked Up Over 200 Hp Over A Conventional 1471. Plenty Boost And No Heat. Look In The Picture Section At The White 40 Ft Motion Or Ask Goldman How Howard's Boat Runs With Them
Down Side They Are Bigger Than A Psi
Up Side You Can Pick Them Up For Around 4500 Each

here ya go Gino...1750 plus

Dude, your 40 Motion is sick......:ernaehrung004:

Put up some more pics...

And the dyno wouldnt hold it:cool:

Thats the one BIG DAddy , need 3 of them Badd boyz in purple :ernaehrung004::ernaehrung004:

Call me BIG Daddy 815-693-3031 :ernaehrung004:

Jeff,
You need more water to that bad boy!! I have run 2200 HP on my SuperFlow.:drink::cool:

He needs more then that 1400hp my friend.
Have you tried 1500plus on the 5.0?
I would suggest the 8.3 whipple but its new and unproven.
Really the old 980 would be a good choice.

I stand behind the PSI. Ask Mike D.
Or Dean Gellner.

What the hell do i know if it were my boat I would run Turbines.

Howard,

I forgot you had those bad boys! Those are massive blowers. Good thing about being big is that they turn so much slower to make the power. For the alcohol cars, they turned at a 1.6 ratio while the PSI turned 2.25.

Dustin

Dustin I need a R980:grinser010:

Ready to go 203 in a 46:cool:

Yes, the 5.0 has made 1650hp on gasoline. The 8.3 is the same supercharger. I've said this a thousand times. The difference, if you drive the male rotor, its a 5.0. If you drive the female rotor, its a 8.3. Therefore, if you spin the 8.3 to 12,000, it's the same as spinning the 5.0 to 19,920. So, with that in mind, if you drive (from crankshaft) the female rotor and spin it 12,000, the male rotor will be rotating at 19,920. If you drive the male rotor and turn it 19,920, then the female rotor will be turning 12,000.

The 8.3 is not unproven, it's worked just fine. It will make all the HP the PSI can make, and it also depends on which PSI, since there's a few versions, some are not nearly as good as others (designs), not to mention from one SC to the next.

The only advantage the PSI has for power is that you run so a huge opening flowing through the SC. Our rear entry can flow a bunch of air, but it's pretty hard to compare to the massive injector hat. It's pretty darn close, and I've gotten it to where I feel confident the 8.3 will out perform the PSI.
