Hey
I've been building a X/F the past year or so. To start, these are the specs.
Forged pistons (DP greece) 8.5/1 CR (going turbo in the near future)
Steel rods (long rods 5.23" if I recall correctly)
HD bearings
ARP all over the place
Big valve head from Burton (Stage 3, double springs, 41mm inlet, ...)
Duplex timing chain (adjustable)
MegaSquirt MS2
home made SS exhaust 2.5" front to back (on stock manifold for now)
Everything is running perfect at idle, cold start is also very good.
Only thing I'm not familiar with is the ignition mapping.
Idle is at 10° for now, read that XF is best at 14°...
haven't gone up in the RPM really, to scared
anybody have a good suggestion or example for an ignitoin map now that it is still NA?
Want to get to know the MegaSquirt a bit better before I give it some juice.
Thanks already.
Philip
