Thought this might be of interest.

It's not going in a Clio but it's an F4R.

I've just got the engine back from the Dyno and here are the figures.

I'd guess its going in some kind of single seater/Locost/hillclimb car - pic looks like a Tatuus FR2000?

Hyabusa bodies as well possibly ...

Edit. Beaten to the spec by the OP. But i clearly reek of geek ;)

lol @ 160bhp - That's a bang tidy looking build and Aero-quip pornography to match!

Need to ask; what's the water pump setup?

The water pump is a Davies Craig elastictrikery one.

The blank plate and oil pump belt tensioner were handstitched by me (as was the inlet manifold).

The TB's were a lot of work as gas flowing them and fitting the bell mouths is time consuming, if I did it again I would use Jenvey bodies on my own manifold.

Engine was pricey as it was Pro-built but not as expensive as estimated.

what management does this run? what work had to be done for the busa bodies?
Click to expand...

DTA S40 PRO the TB's needed a custom manifold, respacing, machining so the bellmouths would fit (have to remove butterflies - PITA), highflow fuel rail and gas flowing to remove sharp steps.

The Black plate on top of the engine, where is the hole for the pressure to escape from the cam cover?
Click to expand...

The engine is dry sumped, there is a breather from the bottom of the block to the oil tank and then 2 breathers from the oil tank to the catch pot.

As a general rule with dry sump systems breathing is done via the oil tank so no need for breathers on the engine.

power seems a bit low for that spec!

I think it's quite good power when you consider the shortcomings of the base engine:-

Bore / stroke limits rpm
Small bore limits valve area hence runs out of puff @ 7000
In and Ex valves on same centres so they shroud each other
Valves too far apart so shrouded by cylinder walls

And also

It's been on a very honest dyno rather than a rolling road with wild tyre / gearbox corrections applied.
Dyno'ed by a different company than built the engine so no need to exaggerate.
A lot of articles on F4R tuning overstate the power produced leading to unrealistic expectations.
