Very good installation, particularly the radiator. Ive dyno tested various lengths on various specs, and as is obvious the short set ups like the DTH ones lack performance right through the rev range. Curves in the intake are not a problem if they're gentle. I tip the whole assembly forward via the inlet manifold or trumpets on a DTH set up then use longer horns. Once you get into the 360-380 zone overall from the valve you start to drop the peak rpm point where max power is made, but can add a little midrange or fill in holes if wild cams are used. 200hp and 170ibft is more than plenty before costs spiral upwards.

Thanks for the time-served expert reply. From memory, we can use the 3rd reflection wave when the track is as you say 360-400mm. Shorter than this use the weaker 4th wave in pulse tuning that's gone there and back once more.

I thought it may come in use for you. You're going to have to watch out for the water outlet in the top of the head if the KR one doesn't angle down like the ABF one. May be worth swapping to an ABF one if possible to give you that extra clearance?

On a drive this setup heads towards over-cooling, due to my low temp thermostat. Circuit use it is perfect, coolant temps in the 90-100 C, oil temps similar

Are you running vacuum advance with a plenum? I tought about doing it with mine on Weber 45s with my ignition management but not sure if it's worth it over TPS.

@@golfmk2 How is the ECU determining load? TPS? I saw the orange hoses and manifold and thought the load sense might be through direct load measurement rather than TPS.
@ABF16V3 ай бұрын
@@ForSunday vacuum take-offs join and go the MAP sensor in the ECU. There's effectively a curve map that splits the load into MAP based speed density for small throttle openings, part throttle, and over this curve it is TPS based. The spark for idle is spark scatter, keeping the rpm stable in any condition

How do you get to the radiator cap?
@ABF16V Жыл бұрын
I don't actually use it, wanted to keep the expansion tank, so the cap on mine is gutted and links to the VW expansion tank. Could be accessed easy enough with the 2 extra top brackets removed and tilting the rad back.
