I've made a start with the Gen 4 RPE-Suzuki 1340cc inline 4 engine, but the max torque is available at a much too low rpm (currently 6068, should be around 7500).
Although the Radical V8 Macroblock is widely used and very similar in every way to the Hartley Maxi V8 I personally prefer the Hartley because of engine design choices:
the Radical has the cylinder banks shifted away from each others, Hartley has a more elegant solution
the Radical V8 has a 72-degree bank angle for packaging reasons. Hartley has perfect 90°, will sound better and have better harmonics
The Hartley Maxi V8 has a little more displacement
Just wanted to let everyone know there will be a 2 day delay on some engines. Some family stuff came up yesterday and today is a Holiday in America “Thanksgiving Day”
Tomorrow I will be picking up where I left of (Friday)
No, Martin, the Hartley V8 is based on Suzuki Hayabusa cylinder blocks and heads (as is the Radical Macroblock).
But both engines have bespoke crankcases, crankshafts, drysumps etc.
It just says so in the video description, but it's a Hartley V8 in the Elise.
