Well as promised I went to HP Logic today for my tune with my new impeller. This was done on a Mustang Dyno. I think Dynojet reads around 20% higher give or take. My previous dyno was done during a cooler time of year. Today was HOT to say the least. I must say the car pulls alot more than before.

List of mods are
Vortech SC with V+ impeller 2.87 pulley
RC 550cc
Walbro pump
Megan headers
Test pipes
Borla TD with X pipe muffler
Motordyne spacer
ACT clutch
Fidanza Flywheel

Mustand Dyno numbers before impeller 332whp 273Tq. After impeller 375whp 319Tq

Add 20% to that for dynojet and it would be 450whp 384Tq. I will be getting a dynojet run in the near future to confirm that.

 

So is this a one off piece or is something they are selling I haven't heard of this can you give me some more info?
