  1. GN7 On the Dyno
    Do intake screens under the carb adapter screw up the carb metering signal on a Roots 6-71 blower? I thought I read somewhere that it might mess air flow up. This is for a BBC 468, dual 850s on a Kuhl inline adapter, stripped 6-71. 5-7 lbs boost lake cruiser build. More endurance than max...

  3. GN7 On the Dyno
    I'm looking at one of the many blower kits available for my 525 BBF that I'm putting in my Hondo runner, I want to use blower carbs on E85 and I will use the boat as a lake rod/ occasional bracket racer, probably no more than 10lbs of boost. So here's where I have questions - some manufacturers...

    What will a motor do on the dyno that is using a roots blower with small carbs? I was using the formula from BDS to see what CFM will be needed with the boost being used. I'm thinking is it will tip over on the dyno. Run out of air being pulled through the carbs. Hope I'm asking this...

    How bad do you think I would be kicking my self if I tried to do a mechanical fuel injection system on a street/strip car? I already have all the parts and I can buy a lot of oil changes for what it would cost to go out and buy all the EFI components. Or should I just kick the bullet, spend...

    This is a really general question, I'm just looking to keep my motor "safe" or ideal. And help me get my motor jetted right. It's not a balls out race motor. I have a 496 with a GM 671 blowing about 5psi and two holly 750cfm 4150s. Just say 6500max rpm. I just run premium yes I know it...
  11. V-Drives
    I will qualify this question so that it about gas. For as long as I can remember, if I saw a V-Drive with A roots blower it was the coolest looking and must be the baddest thing around. One thing that has puzzled me though, has been that when I look at the race results and the records, the...
