whats the most bhp u can get out of a na cvh,realisticly?? carbs,cam,port polish ect ect???

 

ive read of an xr2i with 197bhp but then its just what i have red so dont take my word for it

 

i had 135bhp at flywheel from a 1600 with piper 285cam, vernier pully, antipump lifters, twin weber 40's side-draughts, gold top fuel pump, matched inlet manifold, mega ported and gasflowed head with largest valves available for a cvh. Needed better ignition to get anymore i think from memory. I think that you'd get more with a more modern better spec cam with solid lifters along with proper throttle bodies.

The most i've heard (from a reliable source) is 170 from a 1600cc. Not sure on the higher capacity variants.

 

cheers mate

 

the exhaust valves are too big as standard anyway.
Only the inlets need changing if theres enough casting to support the bigger valves,
U want to ideally use a hemi head as oppose to the lean burn.
So something like an <86 or if your lucky ford used some hemi heads post 86.
Then theres also the efi head which is a hemi but would need an adapter plate. Expect 110-115 at the wheels with like sorted cossie has said. I miss my cvh on a 4-2-1 ashley.

I'll dig a video up

 

spot on - it was 112 at the wheels. forgot to say it had a janspeed system and four branch on it.

 

I think the works RS1600i made around 200 bhp !!

You would have to spend loads to get that kind of power.

Much cheaper and more fun to chuck a turbo on IMO

 

throw in a zetec in throttle bodies good power and will be cheaper than doing a cvh

 

exactly right there. 1.8 or 2.0 good power and torque and uber reliable.
