Hey guys, i recently just had my 1100 dyno tuned the other day, it got 33.6hp i was just wondering if this is what i should be expecting from it?
It was orignially a 998cc but this is what is fitted:
Bored to 1134cc
1100 crank
1100 head (shaved) slighty worked
double valve springs
stage 2 cam
LCB extractors
pulsar distributor
32mm dellorto

33.6HP sounds a bit low to me, Spiro the Moke (1152cc, RE13 cam, 295 head, and a 40 Dellorto) made 47HP at the ausmini dyno day a few years ago, and it was tired.
However, it was on a Dyno Dynamics dyno; chassis dynos do vary a lot, they can't really be compared with each other reliably.

I agree, my 1100 van had 44hp when new. 202 worked head, 266 cam, extractors and 1 1/2" SU.

Yeah interesting, thanks for that guys i think i may start saving for a 1275

nup, getting your existing setup to perform properly will be a lot cheaper, the should be another 10-12 bhp lurking in there somewhere

Unless that Mainline dyno is just reading low (relative to the Dyno Dynamics type ausmini runs have used before).
There are so many variables- just changing sticky race tyres for hard old road ones gives you HP, we found. Same with tyre pressures.

Just had mine dyno'd, first tune since the new rebuild.

43.2HP

1098 +40
standard reconditioned head (head and deck shaved)
45 webber (choked down to 40)
3 into 1 extractors and rc40 exhaust
standard distributor and points
mild cam grind

I also noticed that mine was run in 3rd gear and reached 43.2 @ 100K's

Yea that is a bit low.

Check your tire pressures and it also looks like it was taken in 4th gear - most runs are done in 3rd for a mini so that might make some difference?

When my van was an 1100 , it made 48 bhP ATW on that same (John collins) Dyno. Unknown cam, 295 head lcb, 40 mm web.
Then went to a 1360 with standard head 266 cam 45 mm weber- 60atw
Now 1360 Same cam 7 port head 2x 40 mm del - 90atw.
John is very good at what he does.

Hi Jaz
I think before you go to the big step of changing to a 1275, I would recommend the head be modified first by a reputable head modifying person and then Dyno again
It is amazing how much difference a good head can influence power output in a mini
Next option would be the camshaft as you are unsure on its specs?
