Friggin fire alarm going off is why I'm still awake. Just found my old email from Lysholm, and it states 15000rpms is the max for this blower. So technically we are 297rpms over it's max. Now, I'm not sure if that is max continuous rpms or max rpms period though.

Dont forget.. 15000 rpms on the large rotor means 25000rpm on the small rotor!!

typical ball bearings dont like that very much

WTF? Small rotor... large rotor...? Are you talking about the gearing because both rotors are the same size.

one rotor is 5 lobes one is 3 lobes... yes they are close in size, but one spins significantly faster than the other... thats the WHOLE POINT to a screw type.. 'internal compression'

(different screws have different ratios.. like 6/4, 12/8, etc.. but all in all, they will have a ratio between them)

The TVS uses the same number of lobes on each rotor, its 4/4, which means the rotors spin the same speed and its still a roots style with no internal compression

funny guy...i'll brush that one off since u are pretty smart but since ur not educated on the fact that our intake manifold is very restrictive and when boosting that much the restriction is causing higher temps and higher temps are causing running leaner which is requiring us to run a bigger injector..so yea..the intake mani has everything to do with injector duty cycle...

well they will def make at least 300whp when they get a nice long tube header on there. Thats not to bad, but whats the smallest pulley that you can run with this supercharger??? The TVS with the 2.9 pulley is making about that same HP with more TQ though.

tvs with 3.1 u mean...i believe this is the max they can spin it(from the other threads) and the rest is going to be tuning and supporting mods..

Nice numbers and I loved that idea from the start but For 2 gs you can build your own turbo kit no offence to the twinscrew but that's mad pricey

Nope, he was right with the 2.9! Wrong TVS tester.

This is true. Thus, the reason why I have a perplexing dilemma on my hands. I have an offer on the table for my twinscrew that will allow me to go turbo if I choose to do so. Plus, Hahn is looking to offer a tuner essential kit for their 20G setup which would be perfect so I could finish the rest myself.

idk man i just can see myself going turbo. I love the supercharger idea because its so different, but on the other hand i am not to happy with the numbers that both superchargers are putting out. So idk i guess anythings possible.

I think once the guys with the 2.75" pulleys on the TVS start releasing their fully tuned numbers that might change. I'd be willing to be 325-350 will be had with the TVS, and that 315-325 could be had with the twinscrew. While not nearly as impressive as some of the turbo builds, this will satisfy most people's desires. My real issue is that I finally got the car running damn near perfect and pulling crazy hard right before I deployed with my 2.6" pulley and methanol injection. I just don't want to ruin that, but the quest for more power is still there for some reason. It's an addiciton I swear! All it takes is for one of my buddies to put a half car on me, and then I'm back at it all over again!
