Standard crank but keyed
Steel flywheel
uprated bearings
forged rods and pistons
custom steel valves with uprated springs and titanium top caps
ARP bolts through out
modified cam belt tensioner
The last engine revved to 8200 and this seems to be the norm but why? is there a limiting factor ?
Thanks

As his dad built the S1600 engines for Ford and he races a Zetecs Puma, he would be my starting point.
Mk3 XR3i
R Reg 1.7 Puma
T Reg 1.7 Lux Puma
Now its Racing Puma 072

soft cut 8100, hard cut 8300 - max power is just under 8500. That way it should last! touch wood...

My head/cam specs are the biggest you will go withhout turning the engine in to a 2000rpm power band drag engine so my engine in my opinion is the best spec/use of revs/reliability.
Its also always for sale for the right price or we can build you one fresh for the desired use.

What gearbox do you use, mine doesn't really like changing fast at 9000+revs
I race a 180bhp puma in trackday trophy there a brilliant car, were struggling a little with setup and out of the corners against the 2.0 clios so its having a 2.0 zetec for next year

I just found that 5.1:1 fd but if i wasnt running 17's i wouldnt of needed such a short ratio
To be honest i spent hours looking at the quaife ratios and all they do is use a long first gear then give you the option of final drives, the other gears are nearly identical so i thought for the money just get a short final drive and save a grand
What series do you race in?
