Thanks....complements of Dewey......

 

stock tbss with the tvs1900 and 5.5 psi boost made 458hp and 462tq.

 

what does that get you in the 1/4??
A guy here has one, not a TVS but an older deal. I have never seen that truck move like I thought the blower could do???? I want to say he was 13's in shitty weather.

 

i ran a 11.9@112 with a 112 with basic bolt ons. he only did the g tech thing think said mid 12s. hes getting trans and yank stall so that tbss should be low 12s high 11s with the tvs1900 and stall.

 

how much boost does that 2.9" pulley get you?

 

The TrailBlazer SS MP112 systems are the inlet forward design with the jack shaft. The 2.9 pulley on this system with a stock LS2 will get between 6-6.5 psi of boost.

The TrailBlazer TVS1900 System for the Trailblazer SS is the same as the Classic Truck system. We made some great numbers at just 5.5 psi of boost on the dyno.

 

so no real performance advantage going with the 1900 vs the 112 acording to Norcal.... that kinda sucks.

 

The TVS1900 on the TBSS has not been out long enough to get 1/4 times. We had one dyno at 463RWHP with just 5.5 psi of boost and a custom tune.

 

Wha??? No performance advantage to a bigger more efficeint supercharger? Give it about a month for these to start hitting the tracks.

I think the HP numbers speak for themselves, the MP112 is STILL one of the best superchargers in its size and classification....the TVS1900 is just bigger and better.

 

I would expect a nice improvement over the 112, with less heat and parasitic loss the load should be less...leaving more for the wheels
