Got a buddy that just built one for his mark 8. He did 11.5:1 CR has ported B Heads and cams. Got to 324 at 5200 rpm before something in the tune fouled up and wouldn't keep the converter lock or whatever.
Can't wait for the numbers as I'm kinda back and forth between all n/a power with with added durability or supercharging. Got till next year to think about it but this thread helps as I seek knowledge.
When I first installed the MMR boss50 stroker it had gt40 cams with stock exhaust (weld in flowmasters) I made 300rwhp/340rwtq (SAE). Unknown to me at the time the heli coil TPS Motorsports installed at the time didnt allow for optimum spark (plug wasnt protruding into the chamber). So don't know what I should have made truly. I'll dig up my old dyno sheet lots of peaks and valley.
I'am gonna go with right sabout what Joe said 345ish to the wheels. Also considering Fordnut's #'s before blower, N/A He was 365 and probably a little more done to it.
IIRC the difference between Brian's (FordNut) and my setup was long tubes vs FRPP shorties, electric water pump vs FRPP water pump, ported upper intake vs OE, Accufab throttle body vs OE as well as 9.5:1cr vs 10:1, and 93 octane vs 91 octane. Also, I dont know which comp cams he had but I know he netted 368rwhp IIRC....
I made my guess based on what I made and the fact that Brian has a little more compression and now has hotter cams than I have (and hotter than he had for his previous build).
NICE! Don't be disappointed! Those are nice numbers! Think of it this way: 331 rwhp and 370rwtq is about 414hp @ the crank and you're getting about 1.18hp per ci. That's great! That torque is awesome too! 300rwtq @2,250 rpm! Now supercharge it!!!
Hey Bill, yeah those are good numbers the torque is great! You and Casey are right on point!! But yes pretty happy drivability is even better. Gone is the throttle tip in dive in RPMS and idles again like OE stuff. Cant complain a safe tune for Cali fuel. The tuner thinks the intake and cams aren't a good match because it peaks at 4875rpm. But she'll have to do for a while.
