Went to Futral today to get the truck tuned. The best the Whipple ever did was 503rwhp with the converter locked, 461rwhp with unlocked converter.
The first pull with the procharger on a mail order tune and unlocked converter was 507rwhp After some tweaking by Allan it managed a best of 539rwhp unlocked. That was a nice 78hp gain. Made one pull with the converter locked and it made 563rwhp 533rwtq I'm well on my way to my 600+ goal. Next will be another cam. My current cam was made to work with the whipple and is too small for the D1Sc. It should pick up quite a bit with a bigger cam. Met Edawg while I was there, nice guy and badass truck too

 

Very nice gains.

 

OK now I HAVE to see this truck!

Excellent gains

 

Awesome power and good luck making it to your goal of 600.

 

Are you more pleased with the progressive power on the centrifugal?? They are alot easier to launch Im sure. You made so much more power lower in the band with the whipple, how do you like driving with the procharger? Just curious, why not turbo?

 

Man that thing must be a beast. Good luck on the 600+hp goal, you're knocking on it's doors already.

 

Here is a comparison of the 2 blowers with unlocked converter.The dyno graph starts high, so I cant compare the 2 below 4500rpm's. The procharger does do better down lower in the rpm's than you would expect thanks to being able to run more aggresive timeing since the boost comes on gradually

Whipple-4500rpm's=380rwhp/445rwtq
Procharger-4500rpm's=380rwhp/455rwtq

Whipple-4750rpm's=405rwhp/450rwtq
Procharger-4750rpm's=415hp/458tq

Whipple-5000rpm's=422hp/445tq
procharger-5000rpm's=448hp/470tq

Whipple-5250rpm's=439hp/439tq
Procharger-5250rpm's=470hp/470tq

Whipple-5500rpm's=452hp/432tq
Procharger-5500rpm's490hp/475tq

Whipple-5750=461hp/419tq
Proharger-5750=503hp/460tq

Whipple-6000=458hp/400tq
Procharger-6000=520hp/455tq

Whipple-6250=452hp/381tq
Procharger-6250=530hp/445tq

Whipple-6500=445hp/365tq
Procharger-6500=537hp/430tq

The Whipple made peak tq of 455 at 4555rpm's While the Procharger peaked tq of 473 at 5095 rpm's.
Whipple's hp peaked at 461hp at 5750 rpm's while the procharger just pulled it's *** off to 539hp at 6550 rpms' while keeping tq above 425 all the way to 6550 rpm's as well.
With the right cam the numbers will change quite a bit.
I really like the Procharger so far, it just pulls and pulls where the Whipple just had nothing more to give. I would like to say its easier to launch, but the power really comes in sooner than people think, plus with the 3000 converter and 4.10 gears that doesnt help matters any either.

Now,why didnt I go with a turbo? Cost for one, with the injectors,fuel pumps and Procharger with the D1SC and 3 core intercooler I'm still cheaper than a Livernois kit with upgraded turbo(I would still have to buy the 60lb injectors and duel pumps)
Plus, I do like being different and everybody and there mother is going turbo. I know,I know, the turbo setups are making crazy power, buts there is more than one way to go fast. I'm far from being done with this thing

 

awesome numbers man!!

 

good work man, that's an impressive gain over your whipple set-up. should be awesome with that new cam.

 

WOW

400+ ftlbs at 3000 rpm yes please
