So guys, give me a realistic estimate based on what I'm installing for crank horsepower.
Explorer block, PI heads.
MHS Stage 2 PI NA cams, degreed with TFS adjustable gears.
Kooks 1.75" primary, 3" collector headers necking down to 2.5" mandrel bent dual exhaust with midmount dual in/out magnaflow and chambered mufflers at the pipe exits. No catalysts.
.5" plenum spacer (it's already on the car, don't hate!)
75mm Throttle body and elbow
Don Lasota canned tune until I get a dyno tune
I'm hoping for around 320hp at the crank. Seem realistic?
97 Thunderbird LX (The GT Bird)
PI Swapped NPI motor with some port work on the heads, PI cams, 80mm MAF, CAI that feeds from fenderwell. Jmod, 3.73:1 TL in Mark VIII carrier, Mark VIII aluminum LCAs, 93 Mark VIII driveshaft, PBR brakes (soon to be Cobras), 18x9 wheels, 255/40/ZR18 Tires, Front and Rear strut/shock bracing, GR-2 shocks, Eibach 1.5" springs, 1989 SC front and rear sway bars.
