Wannabriden's D Port Re-Port

Couple of days of stomache flu, but back to getting the last of this data and design uploaded.
Before going further I realized that when I posted the data of the velocity charts I displayed the values and how they related to the targeted values as well as the variance between the two ports. I forgot to display the comparison between the D45F and a stock head. This is where the rubber meets the road...
The charts...

@15mm deep

Don't get it twisted..
That is a 40% INCREASE in Velocity above the stock head. (229 x 1.40 = 320)
Uh huh... that's right!

@35 mm deep

It just gets better as we get deeper into the port...
Here we see a
62% INCREASE in velocity above a stock head.
Wish I could increase my money 62%!

@55mm deep

The trend continues...
Finally at the SSR we see a
74% INCREASE in velocity above stock head.
74%
Nuff Said.
If you can't grasp how that equates to more power... well.... :rolleyes:.
No worries. Reach out and I'll get you up to speed... ;)
Of course it hasn't been dyno tested to see how much more power.
I intend to build a dyno in the next year as I go forward.
Lastly I would say to take a look at how the stock port velocity decreases as it gets deeper into the port.
Contrast that with the tuned port which increases.
No it's not voodoo. Fast Air is FAST!
 
Wanna Play with Clay?

The upcoming part is intended for those with at least a flowbench, it's for those with a pitot tube as well. It covers using clay to mold the port.
It is very detailed. However, there is a slight delay for posting as the clay has to dry thoroughly for each stage of this section...
Stick around.
There are several jewels to be found.
 
Ok...
Minor setback.
Reversed Lovelace around to suck again instead of blowing for the exhausts testing.
Fired her up and she started firing sparks,
Shut it down. Opened it up and did a visual before disconnecting and testing the motors (7 of them) individually.
Tested four so far and have at least one bad motor.
I may have a replacement, but even if I don't I can still test until I do as long as there are no more bad.
I'll finish looking at it tomorrow.

I need the test as I want a before and after for the Port Design How To I am in the midst of.
The clay molding process is a key if you have a flowbench for testing,
Even without a pitot tube. (Flowballs can substitute)
Stay Tuned...
 
Oh well 2 motors.
One is probably shot.
The other can most likely be saved with new brushes. a whole LOT of hours on these motors.
Failed motor was the only used motor I installed. New motors should hit the porch midweek, then I can continue. Meanwhile I've also ordered brushes for the remaining motors

Edit Update.
Motors arrived here early. So installing them, testing all motors and reseal the box.
Takes a day to fully cure.
Testing resumes tomorrow night or Thursday.
