PX 260 mods = speed?
It's time to add some goodies to px260, I ve had a stack of the earlier rxp and px's so I was pretty familiar with set up and expectations , however it feels like I'm starting again with the t3 px260
wondering what speeds to expect with the following set up
8650 ecu, valve retainers, 4 inch air - could I run the standard prop and repitch or would it be best to replace ... Which prop ? Do intake grates increase speed like they did on the earlier models? Is there any value in adding 629 cam?
8650 ecu , valve retainers, 4 inch air, et 137 or equivalent , what prop ? - what at speeds would I expect?
Is there aftermarket nozzles for px260 like there was for the 255 , is there a recommended nozzle diameter other than stock for the above mentioned set ups
thanks in advance..

I haven't read of anyone running grates yet for the PX260. R&D has one and rumor has it Riva has one coming out.

I run the R&D grate It did not add much speed but it stays hooked better.
You can repitch your stock prop to 8900 rpm on stock charger for sure like I did, but add the Et wheel and you will probably need the 15/22 re pitched to your needs.
I would guess 82-85 with a ET137+4 wheel. Stock charger probably about 75 ish. Thats if you have something to eliminate all the stock limiters. With a stock ecu your limited to about 68-70. With the stock limiters you can add all the power you want but it will only get you to 68 faster.
