So... to the brains trust out there with more experience than me.
I am interested in the limit of components in an L series. It's a law of diminishing returns of course and I am once you get to 7000rpm things get expensive but just how expensive and what needs to be replaced.
The reason I ask is I saw a video of a BRE 1600 revving to 10,200 RPM and I wanted to know what or how close you can get to this without a spare bazillion dollars. Saying that, can anyone elaborate n the following?
1. Valve train, the stock valve train is a good design and I imagine would be good for 8,000 rpm providing the correct springs were used. I imagine over that you would want to use a low friction roller assembly to replace the stock rockers?
2. Rotating assembly, I have heard of ford drivers putting L series cranks in ford blocks due to their strength, I have also seen just how close an L series crank is to balanced and its pretty good. if it was perfectly balanced how high could you rev it before swapping for a forged unit? Rods also look pretty stout and same question applies...
3. Oil pump and harmonic balancer?
now of course we are talking forged light pistons, cam designed to suit rev range, bigger lash pads, better head studs cap bolts and rod bolts, competition bearings and headwork including bigger valves, lots of port work ect...
Even without the forged crank and rods we are still talking north of $5,000 for an engine that will not out perform a new engine of the same capacity, but I just want to know what the limits of each component are...
If you don't know why I am asking. listed to an L series revving to 10k
Cheers!
