Will this head be using Rimflo valves? If not, what sort ? |

If not, what sort ? I believe it takes any sort of mini valves, so if the buyer wants rimflo's, then they can have them... obviously if you're shelling out for the head & setup, the little bit extra for the valves wouldn't hurt much |

Hi GR A benchmark has been set

Only makes 121 ft-lb and needs 9300 rpm to get to the 194hp. C'mon GR, show em how its really done

ha,,, there are faster engines out there , 220hp is what i`ve heard over the last few years. But,,, that particular engine (the KAD one that Mick posted) is still being held up,,, you only have to listen to it,,, it`s still not screeming "clean" yet,,, & the last 1/4 of the throttle isn`t really doing much, tells me that there`s still heaps more to come from that engine,,, maybe more cam & Port design work could be sorted,,, & could certainly do with a pile more comp ratio |

Maybe they need a faster dyno? |

Hi Michael No Worries,But with a motor that size i would hope to see 135/140ftlb of torque with the elder head, my group NC motor is making 123ftlb of torque and thats a 5port 1360cc but im 30 hp short of that KAD motor well done to the boys at KAD . Yes Matt there are motors in england making 220hp but not KAD or 16 valve motor bike heads (NA) give the boys at KAD some credit there no fools, and they do their home work, they are a very smart bunch of guys and i dont think there would be any one in england that would make more hp out of the KAD motor than them, been there and met them they were going to make and market my manifolds in england back in 1993.

oh yeah,,,sorry if i sounded like i wasn`t impressed, please forgive me & i really mean that,,, i was only going on the sight, sound & feel of the donk on the dyno,,, & seems to me the thing isn`t quite free spinning (for whatever reason(s) that`s all & please don`t anyone try to start telling me about 9300 isn`t spinning,,, i know what 9300 feels & sounds like i do tend to go more on the "Feel" of an engine quite a lot & i really didn`t mean to make out like i could do better,,, definately not,,, so for anyone reading this--> please understand that point,,, i havn`t made anywhere near that sort of grunt in my life (yet) 
my point was more towards the fact that i just feel that there is more to come from that N/A KAD donk |

Yeah Graham, that is what I meant by "only 121 ft-lb" Using your estimates of peak torque: 121 ft-lb at 6500 is "only" 150hp 130 ft-lb at 6500 is 161hp 140 ft-lb at 6500 is 173hp take 130 ft-lb up to 9000 and you get a whopping 222hp and 140 ft-lb at 9000 is 240hp if you could maintain that torque at that end of the rev range (not saying you can't, but everything is compromised somewhere!) All hypothetical of course, but it shows that it is possible to hold on to your money Graham .
I think you have one advantage over the KAD guys in that you are doing both the head and camshaft - they had to get Piper to make the camshafts for them, so maybe not as optimised as it could be? I also notice that KAD are using 12.5:1 compression on Shell Optimax for that engine. What compression and fuel would you need to run to get your 130/140 ft-lb ? cheers michael |

Hi Michael You need to make 108ftlb of torque to make 194hp @9300rpm I only use 11.5/11.8 compression ratio in all my race engines if you have a very efficient cylinder head you dont need big compression(static)because the more you jam in the cylinder the higher the compression you have when the mixture is compressed, thats why F3 cars with there restrictorin the inlet run 18to1 comp because theres nothing in the cylinder to compress so the less there is in the cylinder the more you have to compress it to get it to go bang. like your standard mini when crusing on light throttel with your vacume advance hooked up your running sum where near 70deg advance and you could run 16to1 with no problems because theres nothing in the cylinder to burn, but it wouldnt be happy if you put your foot down Graham Russell |

This is the inlet manifold for the 7 Port Ken Elder head. It will go under the bonnet of a clubman (just) roundnoses need a bump on the bonnet
These are the new valves, the angle on the back of the valve has been changed for better flow. 
This photo is showing the centre exhaust and the route it has to take to get out on the original 8-Port Head 
It's not as bad as it looks as it flows quite well. This is the 7 Port for comparison:
