highlift cam on standard mpi

[stevie78]

thinking about putting a highliftcam in my standard 1,6 will it run ok with the standard mpi setup its a kent ast 1:confused: as i have on used this cam before with 40s

my mate managed to get his piper cam to work ok on the GTE Mpi that he ran on twin 40's

as far as i know a 'fast road' cam will just slot in, a cam with a more agressive profile would need the valve springs as well

hope this helps

I put an ast2 cam in my old 1.4 astra mpi and it ran like a dog but you may be ok with an ast1 and 1.6 mpi.

and once its on 40s the MPi becomes redundant... :wtf: camming a carb engine is much more simple than an Injection engine.

The AST1 is not high lift, its a "fast road" cam so nothing special. IIRC Kent do Injection specific cam profiles, but whichever is fitted it is advised to get a remap/chip and get it set up properly on a rolling road for best results.

Rich is right. The AST1 is nothing special and you wont see much difference over the standard cam.

an autosprint regrind is probably a better bet.

an autosprint regrind is probably a better bet.

Not as cheap as a bargain 2nd/3rd hand ebay Kent special though.

Just be carefull the SPi doesnt run lean though with a hotter cam in.

i've been keeping an eye on secondhand cams on the bay, & some of them look shocking, and having been ragged mercilessly, then pulled out of a being stripped engine will mean it is probably worn out anyway.
i'd be tempted to get a new std replacement cam, and get it ground, cos thats pretty much what these cam people do with 'fast road' spec cams

cheers goin to stick with standard gsi cam
