Psi Roots

How Are The New Psi Roots Superchargers Working Out? Are They The Best Std. 60 Degree Supercharger To Buy ? And Do They Make Other Sizes Than The 14-71's?

The Psi Blowers Work Very Well They Are The Dominate Blower In Top Fuel. Bill Miller Is Working On Bringing His Back Out But Has Not Done It Yet. Kobelco Is The Dominate Blower In Pro Mod. Alch Funny Cat It Seems To Be All Over The Palce A Little Bit Of Each Littlefield,ssi,psi, And Kobelco, Psi Does Make A 8-71 Hi Helix Which I'm Sure They Would Make In A Standard Rotor As Well. They Are Nice Blowers But A 14 Is Close To 10,000.00 With Snout. It Will Be Interesting If Bill Miller Makes A Hi Helix.

 

Well its on a pulling tractor alcohol wanting to buy a better blower have a littlefield now with cast rotors what would you guys recommend with overdrive restrictions limiting our class

D Kirk Are You Still Running The Class 8-71 Retro Case But Standard 60 Degree Rotors. Do You Have A Overdrive Limit.

 

We bought a new Littlefield with the K-11 rotors in it, and are making 49 lbs boost at 4000 ft, and made 52 lbs boost at Mission BC with a 511 cubic inch motor. We are very impressed.

 

Littlefield is the man!!!!!! Best price, best sevice, all round great guy, same with his staff!!!

we run a 6-71 on our deal (rules). we used to run a 6-71 retro with cast rotors on our engine (littlefield) . we had some spare money lying around (ha ha ) so we bought a 6-71 from littlefield with k-11 rotors in it. 6 more pounds of boost ! ,same speed the cast rotor boost curve on my racepack would peak about 1 second into run . k-11 makes boost kwicker and gradually keeps going up
