It would be interesting to see a comparison of the superchargers at the same displacement.

Enjoy!

"Ad"itorial.....Typical Kenne Bell propaganda. If Jim Bell had any ***** he would take that to an independent test lab, i am willing to bet the farm the results would be different. So why didnt they spin the TVS up? The 2300 can make and IS making well over 800 HP on the GM cars.

One sided, Bell BS. Someone forward this link to Bell and tell him I will personally meet him anywhere, any time at any test lab.

 

I knew about inlet restrictions before, but after reading this article, I really want to check if I have vacuum behind the throttle when I get my truck running.

 

Vacuum behind the inlet is the biggest issue with draw through supercharger. There are big gains to be made if you find the restriction, I read someplace that 3 or more inches of VAC behind the throttle blade = NEGATIVE 25-30 HP.

 

Since I have the stock 2000 truck throttle, you are getting me all tingly with anticipation.

 

I have seen some pretty impressive stuff from a positive displacement blower my buddy had a mustang terminator I guess that's what it is called, but anyway he swapped the factory eaton for the whipple unit and was running low 12's with the eaton, the first day out on the track with the whipple he ran 10.3 on the third run he snapped both half shafts half way down the track, I was there I saw it all and I think he said it dynoed at 750 rear wheel HP with the positive dispalcement blower, all stock engine 5.4, good stuff, but I am very fond of the TVS!

 

Hmmm.......
Inlet restriction whats that?

Where have i been hearing this phrase lately?




Now,I dont sound so crazy do I.Next thing you know blow through t.b. for side mounts will catch.You guys have no idea how much powers restricted in the inlet.Well actually i think BC does

 

Ohh and the iat's with bigger inlets well they are lower to say the least.

 

I am sure that gain was on more boost correct?

 

It's not quite clear if the numbers given for the KB with the stock TB are from the blower dyno or chassis dyno. I'm guessing that the blower dyno is just used to measure parasitic losses as opposed to engine output potential.

So, run through the stock TB, the KB did 664 hp(chassis dyno?) vs 614 hp (chassis dyno) for the TVS. 664/2800= .237 hp per cc of blower displacement. TVS: 614/2300= .267 hp per cc.
