That's a big pair of jugs

[kraftwerk]

how have you managed to fit 97mm cylinders with the standard head stud pattern?? i thought 94mm was the biggest you could go? or am i missing something?

cheers

I was thinking the same thing and the cylinders don't look thinner by eye than the 94's if I see correctly

cylinders are thicker than 94.

[kraftwerk]

so then...if they are thicker than the 94's how have kept the standard cylinder head stud spacing??

Is this for RytöOval?

interesting things!!
Wich cylinder are you  using? wich size of studs (M8 or M10?)
I already have a set of geer/CP P&C in 96.7mm and needless to say that it seems hard to make them go with original stud pattern!!
would you give the external diameter  for  the bottom of cylinder going in the case?

Bottom end diameter is 98.55mm with 0.05mm tolerance to case. Cylinders are (originally 96.50mm) Autocraft with 96.90mm oversize bore, not a true 97mm.studs are m8.

So you use very thin wall !! 
It's would be great to see coment from those who already exeriment this!!

a bit on the thin side at the case end but is that really that bad?, depends on ya stroke/rod length i guess, but if it aint to bad cylinder head end, should be ok! hopefully they will stay round!! do ya think they would take a reasonable ammount of boost(20psi)? if so, then my brother who is kaferboy on here knows where im goin with this..........next season maybe??

[ugly duckling]

as far as i know the 96.7 set ups that ive seen the engine case becomes part of the cly wall. counter boring the case perfect od for tight fit then finish hone the id of the case bore. no tail on the cly. the case does this part. thats how they fit it in the stock stud pattern location. but im sure you allready knew this ?.  why waste your time with that size are you building it for class racing? if not go 4in you can get light wight 4in pistons. you have the heads to go 4in take atvantage of this. a hole differnt ANIMAL MY FREIND then too you can put a REAL HEAD STUD not some tooth pick that will more than likely fail under sever abuse and cause major head FART. good luck on your project wich ever way you go .  UD .
