Great set up and numbers! Can you post a video of it running? I have never heard the Q300 dual behind a supercharger.

 

With the 3" Pulley, are you experiencing any pulley slippage? If so, how bad? I will be running a Vortech setup on my F24 and will have to reduce the redline to 7500 or so due to the increased stroke. I would have to run like a 3.25 Pulley to compensate for the lower RPM and not to over rev the Charger by 53000 rpm

 

I had a little slippage the first few dyno pulls due to the new belt stretching other than that I have had no issues at all.

 

For 3.6 inch and less pulleys I suggest the Reichard Racing pulley. I'm currently running a 3.2 with no slipping.

I Tried to get up this company 2-3times without any success, I will try again. So with a 3.2" Pulley what Psi are you making @ what RPM?
Your making that 525WHP with the 3.2" Setup? I'm Intrigued

 

Great numbers ... Be sure to keep up the good work.

 

Finally made it out the the track last night and lets just say I am very unhappy with the outcome. The best run was 12.9 @ 111mph. With my friend driving the car. The weather was horrible. 95 degrees at the track and probably 100+ on the track. Apparently my tuner set the launch control to low (4500 rpm) Because every time I tried to launch the car would just bog off the line. I have a tone of room for improvement so The plan is to go back with some cooler weather.

 

Better than my 12.9 @ 125mph, lol

 

Just keep calling.


If I remember correctly, the 525rwhp was a 3.4 inch pulley spun to a little over 9200 rpm.
The boost was 1.5 BAR or about 20.3 psi. The 3.2 inch pulley has made a noticeable improvement over the 3.4 inch.
I have not been to the dyno with the 3.2 inch pulley yet.
I've been changing the cam timing and the boost has gone down as the power has gone up.

 

Phil has a little more into his setup than just a pulley.
