Changing Camshaft

[Guest mark little]

Alright all,

The engine is going to be in bits sorting the water leak so I was thinking about upgrading the cam, is there any benefit in this? Can I gain a few extra bhp? Would it be a straight swap or would other work be required.

 

Cheers Mark

You need to look for camshaft which use single valve springs so you don't need to machine the spring seats

Most of the mild camshafts in the Kent catalogue with the code letters FR will be a simple fit

 

FR30 & FR34 are standard rev limit with more lift/torque

I like the FR32 but this would benefit from a bit more compression, light skim and thinner head gasket to get about 10 to 1 compression ratio

I doubt a fast road cam would give much power gain over the normal TVR one.

 

Got a Piper 270 in my 4.6 and I think it needs better heads to get the full benefit.

Cheers for that, he's going to check the wear on the current cam that's fitted and I'll take it from there
