I am running a 2.0l silvertop zetec with Zx9 carbs and megajolt, the exhaust is a standard manifold,
I am off to Bogg Bros this week, any ideas what sort of power figures i should expect?

rollin roads vary an awful lot but if you had around 130 whp it will be more than quick enough

an 1800 silvertop with 2 litre cams will be around the 130 mark and a bit more with TB's or carbs I reckon that 150 - 155 would be a decent figure. Brother in law had 154 with emmerald ecu injection and the Griffin plenum which is restrictive.

I believe coozer had 155 from a 1.8 that Boggs brothers mapped not sure on the full engine spec though

at the fly? or rwhp?

When Bogg Bros did mine it was measured at the rear wheels.

My 1.8 with zx9r carbs and 2l cams gave 155bhp at Bogg brothers, 120 at the wheels.

I have the same set up as you. When I had mine set up it gave 139BHP at the wheels. So this is going to be 150+ at the flywheel. A lot will depend on how you want the power delivery. All out power comes at a cost to drivability.

Finally had the car rolling roaded at Bogg Bros today and got 142Bhp at the wheel in which i thought not bad at all, the car runs smoother, good investment
