Is this a call out ? just passing info ? question ?
Very possible with 10:1 compression, 16 psi of intercooled boost and plenty of exhaust.

Yeah it is. I've never heard of anything higher than 8.5:1.
10.1 compression with forged bottom end is perfect compression for a race 4.6 DOHC (with blower of course). If you compare a blown 4.6 with 10.1 compression and a blown 4.6 with 8.5 compression, the torque difference is incredible.

High compression + boost is the trick of the game now thanx to all the tuning possibilities.

Got a graph ? I'd like to see the tq curve ...
Slowlincoln said:
Uber-fast blown/turbo racecars in NMRA/PSCA run ~11:1 CR with boost. But we're talking 6-7 second cars running on 118 octane, and using a F.A.S.T. XFI or similar to tune it.

What's your plan for ignition? Crank trigger and coil packs, or add a distributor to the cam cover and put a traditional coil in?
If you want my advice, get a FAST XFI - they rule. If I had to do it all over again, I would have gotten that over my AEM.
