me too in fallriver. like I said at the docks they said Dan had pulley issues? second hand info and last year it was the belt or pulleys 2nd stop. also heard down at lotto they had issues but sounded like efi. so your saying it was a drive issue at fallriver?.I got pics to give Dan so I'll ask him about lotto, hope he ran both runs. and it's a bummer if 2yrs in a row he had break downs cause of pullelys or belts in fallriver. hey Mr.ol Dan:coolcowboy:, are there any runs in sept, oct in conn coming up? I got two more days of cutting up trees thens it back to the boat about a day or two to finish at our rate.
hope all had fun over the weekend next month I get to split all this wood I cut up , later Art!!!

I talked to Danny as he was coming into the ramp with Dustin waiting on the dock. He ran in the front at LOTO but didnt want to run the shootout as he had the wrong gearing and the boat was sold. I talk to Danny all the time. As far as run's there's always the CT river run in OCT and we'll get something planned soon.

I can testify that Whipples customer service is awsome...I had a few little issues with a motor they built for me (something they do not normally do...or specialize in.)..and they resolved all the issues at their cost....No hassels what so ever.

I would recommend Whipple to anyone wanting to make big...reliable ...power.

Their customer service rocks!

There's no denying the reliability and power potential of the PSI and it sounds like Roger and the guys have worked out most of the part throttle driveability issues, but in my opinion the Whipple is a much more user friendly package, has more options to fit various needs, and is pretty much bolt on. Just add injectors and a computer of your choice ad go. CPPerf and others have complete pulley sets, and their intercoolers are kickass. I don't know if the PSI can match the cruise efficiency of the Whipple either. I love the look of the PSI and if it was a carb application it would be a tougher choice but for EFI I'll take the Whipple.

Far better than others. Ask any drag racer about how fast they get there SC's. I know some that had to wait 6 months for 1 supercharger!!! I highly doubt there are many that go as far as I go for our customers.

They had a pulley issues as I said before the run, but the issues was the bolts were bottomed out, therefore not tight, that doesn't workout to well. Fixed it before run, they ran, but had other issues unrelated to the superchargers, such as valve train.

Whipple Chargers....Love that hardware!

good....if you dont have a sidemount...

you got that right pqjack!!!!!!

Its nice to see facts other than just opinions. Is there anyone from PSI on oso?

:bsflag:

Pure P sure loses alot of belts ,and thats surely not an incorrect set-up being built & maintained with an open checkbook :coolcowboy: and it was 3 years you were looking for $$$$ coin to continue with the developement ..





and i'd take a Kevlar belt & a PSI and finish a run, then keep throwing belts and snout problems on the whirple ..

They aren't on the marine sites.... yet. They are pretty excited about their products being on the fastest pleasure cat and pleasure vee @ loto this year. They are on www.insidetopalcohol.com from time to time. Here is a link to their site. http://www.psisuperchargers.com/news.html Their blowers get used on everything from top fuel, top alcohol, pro mod, tractor pullers, etc....

You forgot to mention that the intercoolers "someone" built for you over 10yrs ago are still running and they don't leak/burn up! :drink: See ya around Gary!

That pleasure V also had some unreal low end grunt all the way thru the rpm:coolcowboy:

Yea, And it wasn"t using a Whipple :coolcowboy:

My Whipples work great!! Belts lasted all season last year. Put new ones on this year and all good. Need to run them really floppy when cold so they arent running tight when the motors grow when warmed up. Simple but overlooked by some.

You clearly are mistaken, do you know how many hours PP puts on his boat? More than most. Think what you want, sticking with old technology will only get you so far. Ask anyone who has done testing back to back, test the air charge temps, put 8 wide bands on it and let me know what you find. The new sc will change drag racing.

all i can say is i bought a boat last fall with very low hours it has wipple sidemounts the setup is like brand new but when i call whipple for parts or customer support i've got a better chance of talking to god!!!!

Hey Jim, the refurb Freedom US-1 turned out awesome! I like your pulley ratio as well :drink: lol

Is going to be injected only???? I was hoping to see an app for carbs...

I meant to post the same in another thread, the Skater looks fantastic Jim! Looking forward to seeing more pics! :cool:

15 Ibs of boost . Spinning fast!! 1372HP , Two speed Trannys, burning 110. Thanks :) I'm really happy with the way it came out as well!! Thanks again

Comment:

I am surprised Mr. Whipple has not corrected you on this set-up. I had belt issues on my 8.3 and talked to him directly and he informed to do the opposite.

I was told directly by Mr. Whipple to run the belt tight cold and not sloppy as before in order to avoid shearing all the cogs off the belt. He indicated not super tight but with just a tiny bit of give in the belt when it warms up.

As for getting superchargers out quick it all depends on who the customer is. If your a big buyer from Whipple you will get it ASAP. If your average performance boater get in line. Their customer service is also not the best [but still a 4 out of 5 star is not bad] had a pulley go bad due to improper alignment from the factory and I had to pay to correct a problem on the pulley stand which came from Whipple in the wrong length for the application.

Overall, I love my Whipple supercharger...EFI is the only way to roll IMO. It idles and shifts smoothly and put's out monster power on demand. Plus, you set it and forget it currently 135 hours and counting.

Lastly, no one commented on the low profile of the Whipple it fits nicely under my hatch and in most upgrade scenarios requires very little if any hatch mods.

As pointed out earlier Whipple needs to ratchet up the customer service area and fill orders in a timely fashion. As this will certainly earn them five stars. Nevertheless I would certainly recommend their products to any performance boater.

Just to be very clear, we ship standard kits in 3-5 days, and custom kits in 7-10 days. the only reason your kit was delayed is our IC mfg went AWOL. Now that we've invested in our own mfg'ing, thats not a problem. We can't control all our suppliers, but we do our best. I thought that was clear from the many conversations we had.

Any part that has a mfg'ing defect will be replaced at no charge within 1 year of ship date. thats our standard warranty. I think your refering to the idler pulley and the fact that somebody ground the spacer (on locating side) it runs on causing it to not run true.

Send me one of them new whipples for some outlaw drag testing, Hope they are lighter than the 980 series.

they will need to put these on a few Top Alcohol dragsters for testing & recognition to even think about about competing with Roget @ PSI

The E.T.s will be the proof in the pudding :eek::drink:

Not supper tight but with a tiny bit of give in the belt when the motor warms up is correct. My set up when cold is really floppy. Takes about ten mins of warming up before you start hammering it!! :) We always stop and adjust the belt when the motors are hot to make sure its set up proper after new belts are put on and check it every once in a while for the heck of it.

fer sure, my psi c rotor puts over 60 lbs on a 526 ci. 125 over and 9200 rpms
they aint no slouch

Did you ever dyno the C rotor on your gas motor?

Pretty big difference when you only have to turn it 45 over to get the same boost, about 300hp less power consumption and 60deg F cooler temp.

30lbs lighter!

That's some pretty impressive #'s! Do you have any pics of your test model from your blower dyno or from spin testing?

Hello Mr. Whipple:

It is great to hear your delivery and production is now within a 10 day window. I also commend you on bringing the intercooler manufacturing within your control.

As for the idler pulley great recall on the facts but for one point the idler pulley did not line up properly and the installer a [Whipple] dealer ground the wrong side not the customer. Thus, it was not anything I did and should have been covered especially since my delivery was delayed.

I will say that despite our hiccups you do take the time to answer questions from your customers. It is not everyday that a principal of a company does a Q & A with their valued customers:drink:.

Keep up the good work and your products will continue to be recommended by me to all my performance boating friends.

KAP

nope took me too long to get one!
motors were alerady in the boat, it went straight to the car

Gotcha, I was mistaken and thought you already had one.

the idler pulley did not line up properly and the installer a [Whipple] dealer ground the wrong side not the customer:eek:


WOW who was the authorized whirple dealer/installer who did that ???? and you had to eat the cost Kap ???:evilb:

That was a D rotor, which I sold and had to ship for the new buyer.
Interesting comparison we dyoned a 588 psi motor and a 598 whipple 980 blown motor, made within 10 hp of each other. same boost levels, timing etc

Comment:

I would rather not say because I like my Whipple Dealer and installer he is friend:). It was an easy mistake he machined [better word] the front of the idler stand to align the belt properly. When in fact he should have machined the rear portion of the idler stand.

When you machine the front the bearing/pulley will wobble and wear the idler stand down... when your really leaning on it. Whipple should have just said no charge on that as it was obvious the customer had nothing to do with the alteration.

I am really happy with my set-up it puts out monster power rather easily. It sounds like a sewing machine at idle and a jet engine when you peg the boost gauge.

KAP

It will debut at our booth at PRI.

The only difference between the C and D is .25 Liter per rev. At 125 over, which is actually 2.25 over is 20,700rpm, with the new sc, 1.45 ratio ends up at 13,340. Thats a very significant difference in power consumption.

I loved my PSIs....

They only really make sense over 8 pounds of boost. I however am dying to see this new Whipple 10.5/12L....I'd like to build something big and I think this would be a killer combo!

If I built anything again, I would go whipple hands down...
