Hey guys,
Just poking around on the old interwebs and thought I'd try to compare my motor to others with one like mine as far as hp and torque numbers are concerned. I recently dyno'd my motor and got laughed at because the numbers were not what I was expecting. (Although the "Butt Dyno" seems to stop the laughing). It is quick, but I want a little more.
I have a f54 with n/a flattops and a mn47 head. There's been nothing done to the head, only a "lower" lift and "higher" duration camshaft. I've got a 75 non egr intake and a 240sx throttle body with custom charge piping. Also, there's a set of msa 6-1 headers and 2.5 through a glasspack straight pipe exhaust. As far as tuning, I did the z31 turbo conversion with a z32 maf and a Moates Ostrich to change the spark and fuel to whatever I desire.
150 HP and 152 Lb Ft Torque at around 2000 feet asl.
Looking around I've seen much more done to this setup and yield less power. I want more out of this **** thing, and might go turbo. Of course that would mean a p79 head most likely. What I want to know is that because if guys are porting their heads and intakes, why aren't they getting the numbers that I do (I saw several examples of 145HP)?...as far as I've seen so far anyway...and would it be worth it even for me to do the same? Seems to me that with the right cam/tuning, porting is worthless and a waste of time and money.
Somebody chime in that's had some sort of experience with this head. I'm really looking for 200 range, and I don't think I'll get it. Has anyone gotten this before on this setup?
