stu work out the torque to be 190 ft/lb so really happy, specs are piper 270 (really the same as a 266) cam, med head 36 -32 28cc, 15cc pistons, gt17 turbo with 360 degree uprated thrust, 1293cc, oil squirters, straight cut everything,

at avon it was the t3, so this year should be a little better hopefully.

think i ran a 14.2 or something, but the rear wheel bearings where knackered so it was like pushing a truck! rolling resistance was far to high! 13.56 with gas, in full race trim cage etc etc.

max power was at 5000 ish rpm, but i think its due to the downpipe and de-restriction in the manifold, either way 25 bhp for 250 quid isn't bad. I'll let you know how i get on with scruffy tommorow.
