Hydraulic roller cam? experiences?

I've been speaking with Phil from surecam about a hyd roller to suit the 3V's that I will be using in the future.

We are looking at a camshaft range of 3 to 6000rpm, with limiter at 6850rpm.

Aiming to make about 1150FWHP with 15 to 20psi from a significantly bigger turbo than the 45R I have now, either a PT94 or an S95.

Now I know the hyd roller prob won't ring out as hard as the solid flat tappet I have now, but I wanted something that would be able to do heaps of cruising without even having to think about maintennace.

Anyone have any experience with hyd rollers? did you use oem ford lifters or aftermarket?

I was hoping to have 150 on the seat and 350 on the nose, not sure if the oem lifters will handle this???

Personally I'd think that those spring pressures are a bit excessive for a hydraulic.

No not really as hyd roller run the same spring pressures as a solid flat tappet.

you will have to use the link bar style aftermarket lifters.... they are a lot more expensive than oem spider type!!

if your aiming for that sort of fwhp, then don't skimp on parts!!

For that kind of HP id go solid roller, either way roller cams add a lot of cost.
Hyd cams are for mildish type motors, solid offers far better valve control and much better grind selection.

The world block I have will accept std ford lifters, did you mention the link bars because of my HP target? or do you think that the ford parts won't hold up?

Yeah but with a turbo you don't need to use high rpm or large duration cams, just run a bit more spring and a lil extra pressure on the exhaust seat.

A 302 with an F303 std lifters and an 88mm can make over 1100RW under 6000rpm. I just wan't something like that, less power but no maintennance and low rpm.

Just got prices on the F303 and all the parts I would need to convert, 783$ delivered.
