procharger 496 HO supercharger
 

Has anybody tried the procharger 496 HO
supercharger kit.
It looks like a neat kit but got mixed reviews on ATI on internet?

We did a 2002 Formula 353 5psi

How many hours on your supercharged 496HO, and did you use stock fuel system.I did a 3# system logged 40 hrs.

mybe 15hrs. We changed injectors

I am curious how these are doing and if anyone has had a problem with one. What kind of real speeds before and after. I guess the last thing is has anyone lost a 496 to either a Procharger or a Whipple?

Doug

Did you have to change any software/processor or just the injectors? What did you get on the Dyno?
Any problems with brackets bearings etc?

regards

Rick

no ,just the injectors and regulators.The kits were installed without any major problems,some minor , Procharger took care of right away.We didn't dyno. Picked up about 8-10 mph, think it's got more.Ran 250 miles in one day between 4k- 4.5k didn't miss a beat.

BF28 I had same results as Doug, easy 8-10mph. This is with the 3# blower, so far no problems. Install took me 16hrs. Had to do some cutting for intercooler in my hatch,but very clean looking system.

hey i put a pro charger on my 02 271fastec with a 496mag so far been great 3.5lbs of boost picked up 10mph 4pitches in prop size

fmi , what are your before and after prop sizes and speeds?

Went from a 26pitch 4blade at 67.8gps to a 30pitch 4blade bravo at77.8gps 5000rpms wish i could spin a 28 harder but cant change the rev limiter nobody works the 555ecm yet and i dont want to hit the rev limitor cause mercuiser shuts injector pulse down instead of ign down.

FMI, send your PCM555 to Whipple! They can reprogram your computer.

fmi is that a 496 mag or 496 ho ? great results ! plan on pro charging my 1998 26 sonic with 502 efi next year!

ILL try talking to whipple but arizona speed and marine and a place in california both places said no one reworks that ecm 496mag..

Whipple DOES reprogram the 496 PCM. http://www.whipplesuperchargers.com/...sp?ProdID=1190

Hey tried whipple they say they only do there own system so they wont help either i guess im out of luck for now..

67.8 gps?
 

A 271 fastech running 67.8 on gps with 375 hp?
I saw a test on one it ran 63, the fountain was 5mph
faster, that would make it run 72 with an ho.
The formula has a lot more room but I opted for the
5 mph. Either I'm bummed or you have a freak.
Powerboat has one with a 500 I'll have to check
what it ran, seems like 70. My HO runs 67, Enjoy John

Hey my 271 ran 62 on the gps when i first got it but i took the plastic baffles out of the exhust and had a prop worked then i saw 67.8 nothing crazy just did a little work.

Hey fmi
 

I had the stage 2 program done from Whipple and I am running a Procharger with a 5psi kit with no trouble and now have a 5450 rpm limit.

Did you ever run the boat with the Stage 2 kit before the Procharger. I'm interested in seeing if it helped at all.

Yes I did run it 3 months with the stage 2 kit only On the mag there is more room to gain than the HO but my mag gained 2-3mph and my friends ho gained 1-2mph.

Just reporting, I helped install a whipple kit on on a friends 25 Eliminator Eagle 496HO and he gained 15 mph. He went from 67 to 83 and jumped from a Bravo 22p to a 28p with 1.36 gears. The kit changes out all of the stock fuel stuff except the fuel seperator. He has been running all summer with zero problems. I'm very impressed, but the price; she be spendy.

When i told them i had a procharger they said that they wood not do it. did you just order that stage 2 kit do they mess with the timing i dont want to run more timing i wood love to get my rev limitor raised i wood like to try a 28pitch prop and spin it harder..

Yes you can just have your rev limit raised.
