New head units from Procharger!
Yhe f1c fits inbetween the d1r and the f1r. The F1c is rumored to be a steaper geared F1 that will help boost the 4.6 lower tq numbers.
A guy with a test fit car for the Procharger kit says that they tried a F1r on the o3 Cobra and it made awsome peak numbers but they wanted a blower that clould come close to the peak #s yet make boost down low like the base kits P1sc-2. This is what makes me think the F1a will be the larger style blower placed just under the D1r. Cool things from Procharger!
