As you can expect a 10.5t usually wins as it's more consistant, as the infield is very tight so there is a lot of sharp corners where you scrub a lot of speed.
I was wondering, would a 13.5t boosted be a better solution? Keeping things smooth on the infield and boosting on the straight? Or would I just be too slow?
Also is boost useable on such a tight circuit? The straight is usually over in less than 1.5 secs?
Sorry for the questions but despite our racers being experienced., noone has ever used boost on our esc's. (I have a SP v2 lPf which I have never upgraded)
Cheers

I've run my 13.5 on a few tracks that size (Chippenham, Gloucester) against people running motors as quick as 10.5 boosted.
All you will lose against the quicker cars is a couple of metres at the end of the straight, but the milder motor is a lot more consistent. No point being quick on the straight if you can't hit your apexes!
I also find boost harder to drive on a small track like that due to to the uneven power delivery.
Basically, the faster motor is worth a couple of tenths per lap, but hard to do consistently.
My regular club track (Chippenham) has a straight just under 20m (sometimes they lay out a shorter straight of 16m), I find that 13.5 boosted is a shade too fast, and prefer 13.5 zero-timing.
As it happens, I couldn't find a good boost settings at the last Carpet Thrashnal (30x16m track), so switched to zero-timing, threw on a big pinion, and matched my best laptimes. The only place I was losing time was at the end of the longest straight, and the end of a medium straight in the middle of the track. Through the corners I was just as fast, if not faster as it was easier to drive.
