Ok I was just wondering what size the engine capacity goes to once bored out to certain thousands of an inch

etc,etc,etc

Just out of curiousity

i just worked these out so not sure how correct they are

850 is actually 848cc
+20thou = 863.3cc
+40thou = 877.2cc
+60thou = 891.2cc

998
+20thou = 1015cc
+40thou = 1030.4cc
+60thou = 1046.5cc

1098
+20thou = 1115cc
+40thou = 1132cc
+50thou = 1141cc (thas what mine is)
+60thou = 1152cc

if you want any more ill calculate them for u :wink:

For a 1098 you can now get +.080" Hypatec flat tops again. Lovely... 8)
These will give you 1162cc.

Graham Russell has them. :wink:

Any idea on price for them Doc? Would they be suitable for a turbo buildup?

I wouldn't think thatit would be wise to run a turbo because at that capacity the walls of the bores would be to thin and I wouldn't like to be there when it blew up

Hey ben what is the bores for a 1275cc?

Sorry no idea on price really, & for turbo the C/R would probably be too high. You need some nice dished ones... :wink:

So I'll just bump this up here. Hopefully find out what the capacity would be for a 1275cc engine that has been bored out 20,40,60thou and so on if anyone knows

1275cc
+0.020" = 1293
+0.040" = 1310
+0.060" = 1330
bore to 73mm = 1360
bore to 73.5mm = 1380
bore to 74mm = 1400

edit: assumes std stroke.

And the 74mm ones appear to be unobtainium now. :cry:

Steve you forgot 74.7mm, (Triumph 2.5PI) 1426cc... 8)
Block's getting a bit thin, isn't it...

Very thin may even break into the oil ways.
