kelford 272 vs FP4r
#61
On a IX, the FP4R is pretty tough to beat. Faster than stock spool, nice fat midrange power, and from what I've seen they hold more power in the upper RPM's compared to the Kelford 272's. The drawbacks to the 4R's is their rough idle and low speed drivability issues; like everything else in life, tradeoffs are a biatch

Bringin this back folks, need some guidance.
Ive got a IX, Im stuck between Kelford 272's and FP4R's, with S2's also in consideration.
An FP Red is going in in a few weeks. I want a cam thatll spool this thing up quick (before 4000 if possible), make nice midrange power and still deliver a nice amount of power up top.
I will be revving to about 8300 and running 30-34psi on the Red. I like choppy/lopey, noticeable idles. From what Ive seen, most Red's run in combo with the Kelfords but I'd really like to do the FP4R's if I can be sure I wont be disappointed if I choose them over the tried, tested and true Kelford 272s. Haven't seen any cars running a Red with 4R's.

Skip the Kelfords on the IX, they're really doggy down low, especially compared to the 4R's. I run the 4R's on my stock turbo and one of my friends runs the 4R's with a Red on his IX.
