Glad we see eye to eye

 

WTF!!! Where's the video it's been removed, can it be posted again? Love to see what you're talking about.

I like to have that "electric motor smooth" linear power that the positive displacement blowers make. Daily driving is not just a peasure, it's always fun. One of the big things that gets heavy vehicles moving quick is torque. Quick torque is what the positive blowers produce and the 122 Magnusson will hang onto that torque further up the rpm range. As Richard mentioned above, the positive blowers don't require large throttle inputs to deliver suitable amounts of torque and over day in day out driving it gets less tiring not having to wind up an engine in each gear from a stop light. The next objective is to keep the transmissions from expiring.

did anybody keep this? I had to wait till I got home and now itis gone
any help

You can see a video of that and more here . You're going to have to do some clicking, but it's there.

On the third pull it made 670hp. I'd still be interested to see how much boost is gained in having the front entry throttle body. I'd also like to know what the pulley ratio's were. The heat issue show's up a bit by the third dyno run, but like I'd said in another post, the heat issue isn't going to show up that bad during a dyno run. Either way, it's a bad *** 700hp Trailblazer.

 

all (most) magnusson kits have the throttle body in the front.. they just move the pulley to the rear.

 

For full size GM trucks the TB is on the side, using an elbow to pull in air from the rear of the blower. I believe that Zippy was wondering about a direct comparison between the blower with the J-tube and the front inlet blower.

 

There is not THAT much of a loss IF you use the 90mm TB on high boost (over 9 psi) applications.
I am not sure what happened to the video, I will find out whats up on monday.

The "heat" issue you keep referring too is what any engine is going to suffer from in a harsh environment. So the motor was down 40 or 50 horse after who knows how long and how many pulls.....and who knows if that was during a calibration change. You are ASSUMING that is was from back to back pulls and suffering from heat. The one thing I can say is I would lay my figs on the blower housing after each pull.....I would not touch a screw blower housing after a pull like that.

**note** if you pay attention you can see the manifold air temp readings and they do not fluctuate more than 10* +/-
