I know most of the 'Maldon Mafia' both past an present.
I have many friends how are ex-Hart employees who have gone on to work all over the world working for some very high profile companies in all areas of motorsport and engine development.

Steve we know eachother with out even meeting!!!lol
Mike jennings gets to see everything new we decide to use and he has seen my block the tall one with 25mm spacer and steel wet liners and he likes it,pirroe and joe and mike have now seen the girdle kit and like anyone and evrything someone always has better ideas..
To make this perfect id say a steel main cap macined flat in place with the girdle would prob be best but then theres line boring after wards and the making of the steel caps so starting to get very expensive!!
For my application (tall block stell liners 25mm spacer that acts like a deck plate)i think this set up is perfect as were not going to create the harmonics of a std height block squeezing 2.2 cc and 800 hp at 2.5 bar and 9k rpm..
I will hope to be making 700+ hp at and before 7.5k rpm and only 2 bar boost so think i will have a pretty bomb proof yb!! well i hope anyway!!lol..
I have spoke to mike in detail about harmonics etc etc and if my engine works out like im sure it will im going to replicate this alongside the maldon mafia and mk to see if we can get a 1000 hp and hold together but that will be well over a year later than mine has been running just to see how it gets on at the 750 hp mark..
It will be nice to see an engine very similar to my own with a huge bw turbo at 1000 hp and actually see how long it lasts but as said above if in the realms of 8.8-9k rpm then i suspect the harmonics vibration problem will rear its ugly head again??
