Thinking of going to R1 Wurks for the new season. What is the difference between the V7 and the V9? will there be a v9 17.5 and 21.5?

V9 motors are best for 1s racing. Stick with the v7 premium for 2s!

What gearing & timing point should I use for 17.5 & 21.5 on a track this big..

Race line is a little over 900' with the back straight being 180'

Thx-John

I m interested in this motor (21.5 usgt ) but I also have to know why this one rather than another!

Please, I would like to hear the comments of those who compare this motor with another brand!

i would start with a

3.6 in 17.5 with 25-30deg timing
3.6 in 21.5 with 30-35deg timing

most likely your gonna have to tune to your liking. I recommend tuning based on punch, you can add timing until you start loosing punch & take a step back from there. adjust with 1 -2.5 deg increments only.

On the 1.5 TC outdoor asphalt.

Temperature: Whats ideal and whats too HOT.

To keep temps low is it better to gear higher numerically and adjust timing for top end?

I've been toying with an R1 in my 21.5 car at the moment I am geared around 3.8-3.9 area top end is about the same as the fast guys but noticing a lack of punch, was worse when I was geared around 3.5-3.6. I am using 30-35 degrees end bell timing, this thing revs it's box off on the bench (sounds like a mod car) but on the track I'm losing to guys with LRP X20's! The ultra fast guy has some fancy new Trinity hand built thing and he's a good 1-2 seconds a lap quicker than everyone. Any ideas? ESC I have just upgraded to a Hobbywing V3.1 from a Dualsky XC850TF and have a SMC Cap (not that I think it does anything) Car is a T4 '15 and we race Blinky.

Sort of disappointing at the moment, but locally the LRP X12/X20 still seems to be the quick motor (unless you're loaded or sponsored)

is there a serial number on the motor you are running?

ambient temp ?
motor temp?

21.5 is sensitive with timing, based on the information you provided 3.0 with 28deg or less timing is what i would try. you should really only look for the punch, the top end should come on its own.

was the motor bought new?

17.5 or 13.5 ? temps should not be the basis of your tuning. balance of punch & top end are the two primary factors you need to pay attention to.

Why do you say that? Per Steves post in the on-road forum, both are fast with v9 being faster in 1s 12th scale. But the 10th scale 1s spec oval guys at the snowbirds had fast cars as well. I'm running a v9 in my 13.5 TC and its wicked fast. I just wish I knew why the sensor boards pop so easy.

I was just repeating what I was told. If it works for you great. That's good news! I should have said in 1s racing. I have a v9 in my WGT ant it's very fast.

Sorry for the late reply, no serial # on this, bought it 2nd hand, so yeah it's a bit of a pandora's box. Ambient is usually 15-20c motor comes off 40-50c. Will change the gearing to 3.0 and timing to 2 as suggested, thanks!

Can someone suggest gearing and timing for the 21.5t version in UF1 for medium large outdoor asphalt track?
Thanks
