VHPD camshafts

[D Jones]

I was wondering which cams were installed into the VHPD k series engine and which of the Piper camshaft are the closest equivalent.

Oilyhands will know. My first thought would be 285M

Vhpd cams were vhpd cams. 280 duration and 10.2mm lift if I remember right 

They have a little more duration 280 vs 276 and 1mm less lift than 285m cams. 1227 cams apparently have the same duration as vhpd and 11.2mm lift

[oilyhands]

They are the Piper 872 profile, 280 degrees, 10.2mm, the 285M mentioned above give better results. R500/1227 cams are 280 degrees,  11.73mm lift and a much sharper lift profile. If you are looking at similar profiles the BP285H is pretty close WRT to power/torque and Piper also do a hydraulic version of the VHPD, either of these profiles will save the expense and aggro of solid followers and give excellent results.

Oily, thank you once again, I'm thinking hydraulic at the moment and the BP285H is now firmly in the cross hairs as I have a vvc head, verniers and blanking kit

rj,  thankyou for your google search thingy in your signature, I have suddenly found loads of refences to precisely my questions from 10 years ago, which I couldn't find before, And oily answered 10 years ago......? Must seem like ground hog day for you Oily.

Actually, everyone is suffering from groundhogbday at the moment, roll on May 17th

@David Jones

It's Tim Biird you should say thank you to. But.. if you notice, there's a google site search at the top of the page - next to the log out button. Should do the same, I think.

BP285H and BP300H dont work too well with a plenum or the stock VHPD ECU, if you have TBs and programmable ECU then either would be fine.
