If you're good at setting up engines, you dont need a dyno. A dyno just makes things easier but its just a device to replicate road conditions, nothing you cant do on a real road.

so really a dyno tune aint as vital as its made out if you know what ya listenin too?

However Dyno Tuning saves you a lot of trial and error for the optimal set-up especially when using an unusual combination of tuning parts/modifications or experimenting with new ideas. It can also save you money in the long run and save you petrol.......if you stand at the starting line of the London to Brighton Run while 2000 Mini's leave over a couple of hours (most are already at running temperature from queuing up) your nose will tell you from the exhaust fumes how many carb Mini's are badly set up and running excessively rich despite the basic MOT checks........this is in marked contrast to the later Spi and Mpi classic Mini's and of course New MINI's which are running with electronically controlled engine management systems with little or no manual adjustment possible.

Also notice if you read the regular Rolling Road Dyno Mini owners group tests in Miniworld or Mini Magazine practically every Mini tested is found to have very basic problems which could easily be sorted to give more power and fuel economy.......some engines are even found to be producing less power with various badly set up tuning mods than a standard engine would have!

i would say if you have you are doing bolt on engine Mod's eg not removing the engine then no... but if you have had the engine out for internal mod's eg big rebore. Race cam. Etc then yes rolling road Is a good idea

That looks like a 1275 Cooper S block!

I wish there were more good rolling road tuners ! I need mine setup and looked at by someone who knows what they are doing, I need to find some old school mechanics :)

[mini93]

nower day dynos sessions are so cheap... why go through the hassle and trial when you could just pay someone in an hour their done and you have a print out?

[Artful Dodger]

Hahahahahaha that block is destroyed!!!! I wonder how much boost that took!

[scrog]

if you pay someone you will never learn the in's and out's of basic's which can rate you money and could save you being sat on the side of the road one day. But then again if you are not confident enough to undertake the work your self then it's a good idea to get someone who Is. It's all to easy for us to say "oh just do this or do that" and make it sound easy. It would take weeks some time to get My mini's set up doing a little tweak here before going to work and another before i set off good again lol but to me that was all part of the joy of mini ownership.

And thats why fuel injection is is best because id rather just plug the laptop into the lamba sensor and do it on the fly

[scrog]

never worked on spi or mpi I'm old school. i lift the bonnet on one of them and think how the hell did they get all that in there and shut the bonnet lol

We also had 4 star petrol, and usually had lower compression ratios.

[Mini-Mad-Craig]

specially if got a stage one,

ohh yeah, you're defo gonna want to get that ANIMAL RR'd. Stage one, TAME THE BEAST

fuel injection is SO MUCH BETTER!!!!!!!! for any engine over 150bhp fuel injection is a must! ideally id like all my engines on it but i just cant warrent the cost :/

[Ethel]

Or maybe, having forked out a couple of hundred pounds on parts you realise it makes sense to spend a bit more to make sure you are seeing the full benefit of the modifications. You should improve your mpg.

Also, that beast of a 998 is likely to benefit most - a little more power is a much more significant gain on not very much.

Dont get me wrong, a Dyno ( rolling road ) is the best option if one is available and its affordable, but there are ways round it. Back in those days, there was a severe lack of facilities and also a lack of disposable income to spend on such things. Plus used parts were plentiful too, when you went to the breakers yard, you ususally came back with a lot more than you originally went for, I can remember going to get an engine and ended up towing an almost complete car back!

But if you think about it, when you restore an oldie these days and find all sorts of fag packet repairs, oversills and the like, It may be a relic of the past and had to be done on a shoestring budget. I am sure there are a few older members here that can hold up their hands to having done such repairs LOL.
