Not far off for the spec...I had a similar spec make around 175hp with 276 cams...not one of ours, I just supplied an inlet manifold and a second hand DTA ecu and set it up.

What compression ratio are you on Robin?...those cams your using should run with 11:1...so a fair bit off the head if the bottom end has'nt been touched.

Looks like the power is still climbing at 7000 but they stopped reving it there?

The bottem end is completley standard, so the compression ratio will be 10:1.

This is the cilinderhead where you helped me with the dimensions.

Power was still going up, the man who tested the car sad, i stop by 7000rpm because there were standard valve springs in the block. I don't know how far you can rev the std springs?

Cams are from catcams: inlet is 283degrees and 11,5mm lift exhaust 279degrees and 11,5mm lift.

I had a bitt of a struggle of the exit of the corners, most of the corners were second gear and im running the std 020 2y box, i struggled to stay in the powerband.

Now i will fit a other final drive, i hope that helps.

maybe a 180 bhp in it?

I reckon yeah...even reving on to around 7500 you'll find more power up there. ..around another 5-6...peak with those cams will be around 7500...std springs ok there. .some rev them to just short of 8000 but that's pushing it really.

The dynamic/running compression ratio will be too low with those cams and the std 10:1....you'll be around 3/4-1 ratio too low, so another bit of power missing there...you would make yr 180 with ease then...a bit over id say.

You have a good starting point tho.
