Well if that’s the best for falsly quoting Steve and the nearest that you’re going to get to an apology for misquoting Steve on a point that anybody who knew anything about engines would understand I suppose we will have to be grateful. However it is such claims that put people like Steve and Gavin off from contributing and I get very close to that attitude sometimes, it’s cost me well over 250 quid using the internet cafe wrestling with the damned machines forever asking the staff for help in order to help other people with their engines.
I am correcting a posting I made - which I am more than happy to do. I only posted what I thought I had been told - have you never made an error or misunderstood something?
Get off your high horse.
Your internet cafe costs are irrelevant - for that money you could hav bought an old PC and done it from home!
And so Steve B who gave you my article at autosport? who introduced you to Steve? so how did you come to benefit from all our work on balancing and counterweighting, whose idea with Warren was the 1444 cam when your 1721/1736 didn’t work??
Time for some real facts now.
- You gave me the article after introducing yourself to me - I never once asked for it.
- I met you at the end of the Autosport show.
- I was introduced to Steve Smith by Geary Powel who was sharing the Autosport stand with him.
- I met Steve before I met you.
- I met you purely by chance, not by design.
- I chose the counter balancing after converstations with Steve Smith. You had no influence over my choice.
- I take my engine building decisions based on advice from experts in the field. Now if I wanted opinions of art/sculpting/etc I would perhaps come to you.
- The 1721/1736 cams - these are NOT my cams. They are ones used by Scholar.
- Dave Walker and Warren came up with the 1444 to help my engine and Christian Jones’ engine - Christian had an engine built by Scholar using the 1721/1736 and it wasn’t making the power, my engine made more power using the 1227 than the 1721/1736.
- I have tried many cam combinations for Warren over the years and this was simply another test.
For the record the whole point of 100%F1+50%F2 counterweighting is to keep the crank straight and trherefore reduce friction which will tend to help top end power but will have ABSOLUTELY no effect on low/mid range torque. Undoubtably the difference between your engine and Mick Smith 233bhp 158lbft [butts 215bhp 159lbft according to the graph] - both dry sumped [ worth an additional 10 - 12 bhp] is the induction system. unless of course its the liner because everyone I know with a Scholar block is down on power to other similarly speced engines - but at least they are lasting better than the K20 liners which begin to drop power after 4-5000 miles of hard use
Its amazing how you miss the point. A major difference between all Elises and Caterhams is the exhaust system. No Elise/Exige/340R has ever come close to matching the same spec of engine (including induction) when installed in a Caterham on the Emerald rolling road.
Dave Walker plans to run up a ~220+bhp K on his dyno and will run the same engine with the caterham supersport full manifold/exhaust system and then remove it and run the manifold/exhaust system that I use. He will also swap over the induction systems so there will be four combinations to try. Then we will know for sure. When his dyno room is finished he will have more than enough space to run the full exhaust system - most third party tuners don’t have the space in their dyno rooms and their results are compromised by having to run a “dyno manifold”.
How or where are you going to get hold of a heavy metalled 2.0L crank? The only one I know of is the one I have commissioned with Steve. The crank in the Judd is a Kiddie but I don’t think they will sell componants, and the other is PTP’s Stroked Chambron crank, but you will still have to ask Steve to do a single piston test for the new piston weight - and pay for it as well as ask ptp to get you a single throw elment from the crank unless you buy 2 and cut one up ??
Steve Smith has already offered to counter balance a 2.0L crank for me. Scholar sell 2L cranks. And I imagine that any crank manufacturer will make a crank to a specification given to them.
You are not the ONLY person able to organise or commission this sort of work - take a step into the real world please.
It’s nice to feel so ap[preciated

I’ve never asked for your help - but it is good that you share your experiences.
I wanted to bring a balance to the thread. I have real experience of building 220bhp/160lbft engines and have had success.
Whilst its good and interesting that you pass on the results of your gathering of K series tuning information, you put a certain spin into your writing which suggests that much of the work is your idea - when perhaps it isn’t. As demonstrated above.
You also push your beliefs without any evidence to back them up - by evidence I mean real running engines making 220bhp/160lbft - not the 160bhp that you have given a couple of examples of. And those 220bhp engines that have had track abuse and many miles put on them, and are still running.
It would also help if you put up itemised build costs to back up your claims of cheap tuning. I’ve read post after post asking for evidence of your cheap 220bhp/160lbft K series. And don’t try to use Mick Smith’s as an example- he has hade a powerful K fo several years, and like me he built it himself with much help and advice from Dave Walker, Dave Andrews and possibly others too.
If you had already done all the work and had a multitude of running engines to the specs that you recommend then your comments would be justified.
How many people are running a heavy metal inserted crank in a K series? I’ve been running one from Steve’s first batch of three and have been doing so since March for 9.5K miles.
Given the involvement you claim in the crank I would have assumed that you would have been using one of the other cranks Steve did and would have aleady built an engine demonstrating its worth.
It looks like I’m the only person to have done this - and I would recommend using one to anyone building a high powered K.
