Thread: Prop/nozel ???
08-24-2006, 09:24 PM #1
What prop / nozel do you suggest??? - I love acceleration but top-speed's not bad either.
-R&D 1200 grate, PPK
-R&D 1300 plate
-EFI on the way
I'm looking to order a dynafly 14/20. Do I need an 87mm nozel or should I stick w/ a concord 13/19 for acceleration?

For your 2006 GPR, I would use the dyna-fly as it fits the hub of the stator vein properly.
The current reduction nozzle on your ski should be an 85mm nozzle.
I would keep that on there.
I would also look into increasing the compression (mill the stock head) slightly also.
This will give you some bottom end power.
Get the with EFI guru's and see that they recommend for safe compression with your current mods and the proposed EFI settings they may suggest.
If you don't already have one, get a good aftermarket tachometer for tuning purposes. (Pet-2100).
See Jerry's online store for this.

OHHHHHHHH NOOOOOOOOOOOOOOOOOOOOOOOOOOO you shouldn't have waisted your money on that!!!!!!!!!!!!!!!!!!!!!! Is it to late for a refund? IF anything goes wrong you can fix it the right way with the info you get here. They will just take it factory spec and may leave you worse off IF you every have to use the darn thing...

Buy an extra head (or afterarket ones) and if anything where ever to go wrong you could pull the efi and the heads in about an hour and I would be "under warranty" again

I believe your stock gasket is double layered.

The DF 14/20 is going to be too much prop for a stock motor.
