My roots blower deal was dry and i needed to be towed up and back.Worked great when i had consistent crew chief,but now with very limited help its so much easier to drive the procharger up and back..no assistance needed.Was pretty cool at an ihra track last year ran two back to back 5.96 and drove her back to the pits.

No more wheelie bar!! Car leaves in the .960 to .970 range and never wheelies or gets weird outta the hole.

No more worrying about weather swings which with a roots blower meant alot of pill changes.My procharger runs an apd carb and has main jets and air bleeds which are way more forgiving unless you have a massive weather change.Cant even count how many times ive seen the blower guys lean a motor out missing a pill change.

My procharger runs a front drive which means no more worrying about blowing off a belt at the worst time.She uses gears and a lil gear oil with virtually no maintenance.

And lastly if your a roots or screw blower guy i sure would love to see you womp womp your throttle at 1000 to 1100 feet...unless of course its 4th of july!!


So the Procharger does leave softer than similar Roots or Screw type?

Sry but you can peddal a blown motor w/o issue unless it is TF with 110gpm pump moving a river of fuel. Not sure where idea it would cause issue comes from. Now how car would react to it might be problem,but engine wise none.

Pedaling a blower motor is one thing but ripping the throttle on the top end is another. There are racers doing it but its extremly hard on the crank and rods. Someone who does it on a regular bases told me each rip is equal to 1 pass on a aluminum rod and they change crank and rods a lot

I saw evidence recently the cogged blower belt doesn't like it either. That's the reason I went with a 12-rib belt on our ProCharger & I've been doing plenty of ripping on the top end. Wink

Motor I am building is a 565 BBC with 871 stripped blower. I may go to the Whipple 510R? later.
Several reasons, class I like to run the Procharger is not allowed and I already have the 871. I do not need a lot of power to run my index and like to be conservative and easy on parts. Which is why I like the screw blower it takes less power to run it to get same boost making it easier on rotating assembly and possibly more forgiving on the tuneup.

Procharger is a pretty neat deal if you can run them.
