There are on road racers racing with them. Myself being one
I will be attending Reedy 2012 in a support role for SchuurSpeed Motors. There are a few from the Northwest attending and a few from SoCal that i know will be racing with the motors in both 13.5 and 17.5 classes.
website - schuurspeed.com and if you have questions lmk.

Any tips on a good starting FDR for these, in 17.5?

Best to start somewhere around 38 degrees of timing and 3.8 FDR and adjust from there.
I've gone as far as 3.7 FDR with 40-41 degrees of timing with a fan. This was at the Roar carpet Nats and also at my home track and I didn't get the motor past 160.
That being said, I'm still experimenting with timing vs gearing so please share your results.

Of course it depends on how much brake you use , how tight the infield is, etc.

I haven't run on a track that large and flowing, but I would try closer to 40 degrees timing. It should give you more rip off the corner and also more top. Temp every few minutes, then experiment with more gear with less timing and vice versa. My guess is you'll never go below 35 degrees of timing.

I had a short testing session with my new 17.5, yesterday. The timing system was off, and I was on the track alone so it was hard to gauge the change in performance. I can tell that this motor has more power than what I had before, for sure. It seems to have alot more speed on the straight.
I ran it with a 3.85 FDR at 38° timing. The motor was 124° after about 4 minutes. I don't think I'll change anything until I'm able to run a heat with other cars, and see where I sit.
I've heard different theories on how to find an optimal gearing. Any recommendations? A local guy mentioned to me that each brand of spec motor tends to have its own characteristics. Some are lower RPM with lots of torque. Some are more of a high RPM.
Should I keep getting more aggressive with timing and gearing until I reach a certain temp? Is there another way to find the sweet spot?

where's the stickers??
I ordered 2 x 17.5 from trackstar. 38 days later they arrived in Australia.
i've heard they're good and look forward to soldering them in soon but no stickers in the box for my car.
