415HP from 318ci IS POSSABLE!!
Well, it seems to me that we can critique the various builds down to the bone on the issue of price - but Im not sure it proves anything - especially if you don't know the builders track records.
I’d hazard a guess- and its ONLY a guess, that a large slice of Moper’s increase costs lie with the EQ heads and valve gear, as opposed to Bobby’s cast ported “factory” set up, and the fact Bobby does his own machining…that’s $1200 right there.
So its “horses for courses”, plenty of guys don’t want to take the risk of core shift in porting cast heads, and will see the EQ heads as a “necessary”, not an option.
Others will see the budget approach of using cast ehads and say "cool deal".
Moving on - What staggers me is that the cam profiles are not huge, and that even the lowly 318 head can produce real HP if worked right.
I do have some questions though,
Bobby – in the 322 post you claimed:
470 HP at the flywheel and 376 to the ground.
Yet earlier in this thread you mentioned you’d change things for a more streetable build - and claimed:
This engine would be good to 6,000 RPM's. This engine would make 219 HP and 384 FT. Lbs TQ @ 3,000 RPM's and 484 FT.Lbs peak @ 4,500 RPM's and 501 HP @ 6,000.
Did you mean
401HP @ 6000 or am I missing something? Shouldn’t the more streetable build be lower in crank HP?
Bobby / Dave – I’d appreciate both of yours recommendations on an appropriate gear ratio/stall/tyre size for this type of highly strung 400HP 318 - What do you think the minimum should be to avoid this type of engine behaving like a complete pig for street duty?
