I still debating wether to get a Piper camshaft kit or not! I had a chat with someone at Courtney and they said it is not really worth it as it is only a 1.8 single point injection but if I did get one it must do something!?! make it pick up a bit better around 3 or 4k rpm? rev quicker?!? The Cav at the moment is a bit flat in the lower gears (3rd, 4th & 5th) anyway around 3-4k and I just want a bit more omphh!
I am going to have the Cav for a few years yet and I am used to the 'power' now, I just want to do one last 'performance' thing and leave it like that.
Please give me you opinions!
PS I had an indicated 125mph on a private road in 4th yesterday! I was very pleased and there was a bit more to go! and another gear!!
Is your existing camshaft worn?
If it's OK, then a new cam will only make it breathe a bit better at high revs at the expense of low revs. In city traffic you may find this annoying.
It's a 1.8, don't expect miracles.
Use STP total system cleaner to clear up any accumulated gunk, make sure your filters are all clean and leave the poor thing alone...
Taking the head off, cleaning everything and lapping the valves will give you more power everywhere, if you insist on increasing power a bit.
You'd be better of doing something about the 1.8 SPi for starters.
It's the flow limit of the single injector that's holding it back.
Maybe fitting a single carb, or better getting hold of a 1.8 or 2.0 MPi engine. Then start thinking head and cam. The cam would be wasted on your current set up, losing you bottom end torque and gaining very little at the top.
A possibly simple route would be to stick a carb on instead.
Converting to MPi shouldn't be "that" difficult. I think there's someone on MIG who did such a thing.
It's basically moving all the different bits over. Plug and play from then on as has been said.
