DIY INTAKE MANIFOLD porting for Natural aspiration
#46
Sorry guy's it has been awhile.
Finally dynoed the engine with 95 octane, and stock (20btdc) timing. The results are very impressive.
Can't wait till the PDM cams, and my ported intake runners go into place.
All most finished with the runners. Please keep in mind this was done on a mustang dyno, a dyno jet would of showed higher gains, not to mention I didn't advance timing is stock!!!
Shooting for 185RWHP when the manifold, and cams are installed.

Well the problem is that the SAFC isn't an excellent tool for adjusting the A/Fr's, to the stock ecu. What you are seeing is a manipulated stock A/F ratio. If that A/Fr was more tuned via ecu (fuel MAPS) there could of been room for a lot more HP, not to mention changes to ignition timing.
Secondly it was harder to tune using the N60 MAF. Why there was a drop in torque was simply because the mixture went super rich where it shouldn't of been causing it to drop and come back up.

The PDM cams actually show more extended power through out the rpm range, and brian crower hasn't shown any peak HP results for natural aspiration, which leads me to believe that those cams were designed more for forced induction.
I truly feel that the N60 maf with the PDM cams is the ultimate in peak power as well as extended rev. Although the PDM's cost more I think they are the better combination for the application thatI am looking for. Although don't take my word on it as the engineers at freshalloy tend to disagree and think I am a retard, because I don't have a B.S in engineering.
I have big plans on doing the head after I purchase the AMS fully counterweighted crank. I won't be doing to much porting though as the head IMO almost meets optimum velocity. It does needto be cleaned up.

BRG is going to measure the bearings and install crank for the bottom end. They will also supply the flow bench for me when I do the head work. BRG will have a guy balance the fully counterweighted crank for me. Way ahead of you...
