So it’s the new year so it’s time to get ready for Tsing season! I have my money for the high helix 8-71 blower also got my programmable distributor for Christmas, just bought on eBay a System 1 reusable oil filter, now all I need is valve seals.....it’s all down hill now!! Also bought me another bump box......cool!

I don’t know.......good question. I guess it depends how much boost I can get out of the high helix 8-71. With the better rotor design I will get more hp with it being more efficient.

I accomplished what I wanted to do with the set up I had.....7.90’s in 80 degree temps on only 12-13 lbs of boost.

So I called The blower shop to see about a Blower and they said 6-8 weeks.......damn lucky i didn't wait to the last second to order. High Helix......Billet Rotors.....Billet Case.....Teflon strips on the Roptors and everything inside Anodized and YES it will work with my BDS intake! Guess my Blower will be up for sale.......without input shaft......Best offer!

Right now I’m staying with the carbs, the blower will be more efficient and will take less hp to turn......”less yank on the crank”!
I’m not sure how much more boost I will get, car can only take so much power.
