Cams... share your knowledge

[5tox]

Im using a 2.0 pinto as an example, there are so many cams about how do you know which is best?

 

if one comes on cam later through the rev range does it mean it gives more BHP?

is it right that cams with a power band later down the rev range give a worse idle?

 

what would be an adviseable cam to use in a 2.0 pinto on 45's, light port & polish

not an everyday driver but would like instant power for lots of sideways action, wont be revved past 6k

 

any info or advice on camshaft choice will be gratefully recieved, its just something ive been reading up on and cant quite seem to get my head around it

The 2x cams ive read up on which seem to fit the requirements are the popular Kent cams FR32 and the Piper OHCBP285 'ultimate road' cam

 

the piper cam appears to have a better power band from 2200-7000 rather than the kent cams 2500-7000 and also gives an extra 22bhp over the kent cams 16bhp increase

 

has anybody had any experience with the 2 cams mentioned?

 

is the piper cam really any better or just looks it on paper?

Ignor the bhp claims. Unless you're using a suitable big valve head and compression to make them work. Cams are all down to your intended purpose. I'm using a gts2 a lightning rod cam as it has a very high lift an fairly long duration. Gts6/7 has same sort of lift and less duration. These all required careful machining and correct compression to get best results. There's plenty of things that you need to do to get a pinto to scream and tear up the Tarmac.

Do a search on google for puma race engines. Has a guide there and worth reading

I've used both cams you mentioned & much preferred the Piper. The FR32 was too lame for me
