Stock RXT RPMs

[lmiranda]

I have 6hrs in my RXT and still only seeing 7600-7750 RPM at WOT. Should I be concerned? Temp in the 70s with slight chop. I did a search and previous posts mention 8000's RPMat WOT for stock RXTs... I am concerned that my break-in was too aggresive, I did a few WOT run 5-10 seconds withing the first hour or so... Hoping the engine will open up soon.

my 07 rxt is getting the rpm's as yours. Top speed is around 63-64 on gps. I'm no expert but we should probably start trying new grates, props, ect.....

yep, i am seeing the same speeds... 64.4 max on GPS... just finishing saving up for the SC washer swap. Hoping we get a few more free RPMs as the engine gets more hours. Anyone know if there is a majic number of hours after which what you got is what you got in terms of RPMs?

I would say that after 10 hours you might see a difference in your RPMs and top speed.

A too agressive break in? Not likely.

I was a lot harder on my '05...and I consistently saw 8100 with spikes of 8150 in the same conditions.

Get yourself a Solas 14/17 and your RPM's will be around 8100. Night and day performance gains by just going to this prop.
