basically my goal is to get as much power out of my 1100 special every one i know thinks that engine size is the key to power but i want my mini to be diffrent i already have a tuned 1275 mini but the 1100 is still faster both minis will be going to Harris Motorsport for a rolling road setup when they are finished and then i might supercharge the special the 1100 has been rebored +40 to 1133cc it has a weber 28/36 down draught carb stage4 head AE pistons on stress polished lightened and balancd rods a wedged balanced crank and a ultrilight flywheel with a grey race clutch i dicided on a piper 270 cam and vernier pulleys and i used a metro turbo box with a 2.9 competion diff + lots of other bits im interested in hearing other peoples veiws on this project and if anyone has any ideas how i could get a bit more power let me know

That sounds like a beaut set-up, going to use 1100 crank and + 40 thou pistons in my set-up, and supercharging mine too, check out my project lol, good luck .

more cc I have a imp pistoned 1100 block at minispeed which i will be doing a thread on when i get it here in December.
have you strenghten the middle bearing? the rods sound great as the crank, I would fit a 1275 head that will make a bit and dump the dizzy and get a megajolt. maybe dry deck the head/block.

Looking forward to seeing what comes of this. Been wondering what the 1100 is capable of.

me to! a Berner mini club member reckons he has had 69 hp out of an 1100 and thats with a speedwell ally head, never mind maybe with time he will be able to do better!!
I would like to see at least 80hp
The aldon is good the megajolt better you have better control over your ignition timing when its important.
you must do the main bearing that is mega important on that engine,

ye ive also been told the big ends are also an issue i might use ARP rod bolts and i will be looking into some sort of ecu in the future when i supercharge it and hopefuly i will see 100+hp i already have alot of torqe steer i cant wait to get it back out on the road

this is going to be interesting! i have an 1100 block, imp pistons and a 12G295 head with twin carbs that i am hoping to build up over the winter! ive always wanted to do somthing that isnt just a 1275, someting different!

[dave-88_123]

i know have a set of 1275 pressed rockers to add to my spec as they are the highest ratio standard rockers and should make a difference and ive just finished assembaling the block and gear box

Hey how you getting on with your engine?
here is that big bore 1100 I was taking about 68mm bores.
