Well, I finally have some time to catch up to things after traveling to Florida and the Holidays and it is time to post up the full Dyno numbers for the Power Ported Performance 426 Stroker motor (look for pricing posts tomorrow).

I am very happy with the numbers this awesome package is putting down and the driving experience leaves you, well speechless and giddy at the same time. Several people have taken this car for test drives and reaction have been fairly humorous to watch. It's funny seeing a grown man start whooping at the top of their lungs or giggling uncontrollably, or just overcome to the point they can't express the excitement they are feeling driving a Power Ported Performance Stroker vehicle. The torque is just insane.

I will post up some video I shot of one test drive if I can get the High Definition video conversion process to work right from the new video camera. Anyway on to the numbers...

The LX platforms get about a 17.5% driveline loss from crank (FWHP) to the wheels. This equates to roughly 560 fwhp & 620 fwtq at the crank. Again, right in line with our engine dyno numbers...

Here are the rear wheel horse power numbers. As you can see it ramps up really quick... right up to a steady 463 hp!

But even more impressive are the Torque numbers... (511 lbs of it!)

So, who's ready for some kick @ss, tire shredding, vehicle launching torque?

Right now I am running at about 11:1 flat at WOT. I could get it to be leaner and pull a few more HP / TQ out of the engine, but I have Nitrous plans for this engine and want to keep it a little rich on the fuel side. Other than that I have a special PCM Flash for the 426 Stroker that provides plenty of benefits.

Best Regards,

What would something like this cost and what kind of turn around time frame should one expect?

Thanks.
