Up Grades on Stroker-Suggestions

I know this is an old thread but I thought I would give you an up date.
Went back to the dyno to redo the A/F ratio and see if we could get more timing out of it, we also dropped the exhaust to see if there was anymore improvement.
It was running miles to fat so that's was sorted out, more timing and dropping the exhaust made no more improvement.

Headed to the track for a run, straight off the trailer in full street trim running a full tank of 98ron, 36psi in street tyres, launching at 1800rpm it cut a 14.70 at 109.9mph, traction was a major problem.
Dropped the tyre pressure down to 26psi, launched at 1800rpm and cut a 12.70 at 112.9mph, reaction was .810, 60 feet was 2.09. Crossing the line at 5650rpm well under the rev limit of 6150
Going to buy some ET radials, thinking of changing the diameter from 28" to 26" to get the revs up a bit.
Suspension still needs some work although weight transfer looks good along with rear separation.
