so???,,, what`s the problem John,,, get to it then,,, crickey i`ve been saying it for years & your the man to make a 5 main block & crank & yet you still jibber jabber & fangle dangle still stepping around the idea,,, just god-damn do it will you

Awesome result.
Minivanless, but reluctantly happy living with the decision. There'll be another one day.

200hp - we'd need a 5 bearing crank for the revs that would need.lol! john, just think what was getting said 5 years ago about a 150bhp n/a mini engine Yes i moved to the darkside |

at least 10k, probably closer to 10700 On 28th Aug, 2011 Kean said:

Very impressive John, what is the maximum this will rev to? I seriously doubt it! |

On the Kent engine they used to remove 2 main brgs to reduce friction and improve revs I think the 3 brg has a bad press , someone with enough money to waste on crank development and engine destruction could achieve those revs ? |

We're getting nearly 127 hp/litre from the little 1380 A now with the K head at circa 8700, on this engine the rev limit is 9000rpm, if allowed free regin the motor would still make plenty of torque at 9500rpm, due to gearing/power spread its not necessary ot buzz it past 9k for hill climbing

colin ashbourn at Kad told me they used 10400 on the spaceframed car in the late 80s- early 90s ,i'm assuming this was short stroked |

[under the class size anyway] short stroke , mega revs job I ask the question as to how high a 3 brg has been revd to , only as until someone actually builds one with cams that give power to 10500+ rpm no one will know if it will go pop or not . All the maths are useless until someone with deep pockets, as John put it , gives it a go . I'm sure i've had 10000 on over revs without any signs of distress |

I belive some of the migs have been "buzzed" to nearly 11k, bit thats not the same as being used. On 28th Aug, 2011 Kean said:

That wasn't the idea of this build Paul, the engine was built to fit class regs and so far its doing a good job of spanking them nicely!

As Joe says on a 1380 you'd have to run to 10500+ to make it 200hp, the Sprint cams are perfect for 8500/8700 peak power to move past this we'd need to invest in custom springs and larger dia cam buckets to increase lift and add a little duration- the Sprint cam is designed to run the max lift possible on stock springs and the max accel rates on the cam ramps to keep it on the cam bucket. ! why should the accel rates on the cam ramps change if using more duration john ? stronger springs arent hard to get from, say ,crower ,and the same ramps just more duration would work ,if theres enough head flow .:) Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM |

Theres nothing wrong with the duration of the sprints, just lacking a wee bit of lift- its not the poundage of the springs either (valve float is 11000rpm with stock springs)its their coilbound height which is limiting - believe me there are no springs out there to do the job of providing fitted length/seat poundage and coil bound height which allow 12/12.5mm of lift - I've tried for many years - as with the valves I may have to have specials made if we go any further than this engine spec

Yeah Matt a capacity of 1600 or so would bring the revs down to under 9k to make over 200hp n/a jsut not with the bore/stroke in a "conventional" mini block though!
