If your running in a stock class that runs to BRCA rules then you won't have a choice of what wind motor you run. I can't remember what winds the stock motors are (double i think, not realy my area). Realy the best tuning option with the stock motors is whether you go for a double or quad magnet can.

I prefer quad mags, they seem to have so much more in them...

BRCA rules only allow the use of a 27 single i belive, but for that track i recomend a high reving motor (quad mag) with a fairly high gearing.

what car will you be running?

Ive been to that track (its Bashley, South Hants). Trust me, its tiny compared to most. Get a high torque motor and gear it around 6.5 to 7.0 to start with.

Yeah its bashley, you are fast if you manage a 19 lap in stock. V fast. so thats like what... 300/18 = 16.6s. If you can lap in under 17s your doing well, thats an idea of the size of track.

I use a Vega stock motor there and geared about 7.27. I perhaps should gear up a little for some more pace, but my motor gets warm as it is. And as i race more for a bit of fun id rather not cook my motor for the sake of a bit more speed! :)

my mission :)

i have a 24 t pinion in at the moment.

All depends what layshaft pulley he is using.

With a 20T layshaft and stock spur (86) your looking at a 6.5 FDR.

With a 20T layshaft:

22T pinion = 7.04

21T pinion = 7.37

With a 20 tooth layshaft i would run a 21 tooth pinion.

17T layshaft. Now i believe the IR with a 17t is 2.1. So, a 17t layshaft with Duff's 24t pinion will give us an FDR of 7.53. A little undergeared, but not a bad starting place.

A 25t pinion would give FDR 7.22.

I think as your going for a quad mag, starting with a 24 pinion, 86 spur and 17t layshaft will be fine.

If you were finding it a little slow, i would either;

a) change the spur (maybe an 84 - fdr of 7.35) But this means a spur adapter as i dont think schumacher makes an 84

B) (my choice) run the 20T layshaft with a 21t pinion.

IMO 7.22 (86 spur, 17 layshaft, 25 pinion) will be putting a lot of strain wear and tear on a quad mag - but you never know it might be ok as every motor is different.

well firstley im not getting a quad mag the tm monster is just a 27t.

i will be running it with the 17t lay shaft and the standerd kit spure duno how many teeth forgot and will also be running a 24t pinion.

stock spur is 86. That gearing combination will give you 7.53. As i said before, a little conservative, but at least safe. If you were to use the 20t layshaft it would be overgeared and risk burning out the motor.

run the 20t layshaft pulley

it allows you to run the belt looser, thus the car will run more efficient.

thre is also less chance of the belt jumping, as the belt 'wraps' around the pulleys more....that is why you can run it looser.

sorry??  :huh:

lol no probs it was my falt for not explaning to well.

Rear belt tension isn't adjustable.

yer thats what i was thinking......... ;)

okay so with a 24t it will be a bit under geard right so.... what size pinion would you sugest to get it just right?

Theres a couple of things you can try.

Firstly by going up a tooth on your pinion. You can also go up 3t on your spur (which is about the same as one tooth on your pinion(although slightly different). You dont really need to find the EXACT gearing, just the right tooth on your pinion which helps you keep up with the rest of the field.
