That much power at 4000 is amazing. The F1A really makes alot of boost down low and was the first thing I noticed when I upgraded from the P1SC. The P1SC made about 2 pds at 3000 whereas the F1A makes about 7 psi at 3000 with similar impellor rpms. The impellor is much more efficient on the F1A. I'm pulleying mine down because I can't find enough traction to justify all the power.

 

Silas-
Congrats on what you've been able to acomplish so far! Glad to here everything is working for you thus far. I think we're all waiting for your more complete dynotune. Good luck!!!

 

Actually I only have the F1 not the F1A. I'm pretty sure it'l put down more than that but time will only tell. I never did get to see how much boost it had got up to w/ the torque number either. Hopefully in the next 2 weeks I can get it completed but my time is short as we leave in June and I ship the car in May. Very tight schedule.
Thanks Boosted. It feels good to feel like I finally have accomplished something. I'll be sure to post the final results and video when ever this is. Hopefully sooner than later.

Silas,

 

Pic of simple ProChg idle arm stop. Mounted to 3/8 threaded rod used for water pump mount bolt. Extended length to mount stop. I found about a 1/8" to 1/16" gap is needed to allow the spring to work. The stop keeps the idler arm from large amplitude angular deflection swings when tight tide tension moves to top side of belt. Hope this helps. B>
