Morning all. BIt bored and wandering about my mini sitting in the garage! Shes new to me, a 1986 austin mini, The Chelsea version.

So, my mum picked it up for me (i cant drive yet!) and she said she got it to about 65mph on the motorway. People tell me to make it go just a little bit faster you can fit an airfilter or induction kit...

Please could someone enlighten me on the subject and tell me what they do? will it give the car a bit more power/speed?

thanks, stu

your best bet for a little more pull is a stage 1 kit, that basically consists of;

A K&N style filter
A larger carb needle
A wider bore inlet manifold
and a wider bore exhaust system (many people go for the RC-40 system)

and don't forget to get it properly set up on a rolling road afterwards!

thanks! and this would cost? sub £100. It also sounds like this could play a role in my insurance, yes?

Then there is something wrong with it. even in standard trim a 998 should do over 80 easily. Still I know what mums are like (I have one you see) caution is the name of the game.

Give it a good service, plugs, points, rotor arm, dizzy cap, leads, oil, filter, air filter.

And also, clean the cab (use carb cleaner) you'll need to get the dash-pot off, so go and buy a Haynes manual.

Forget about any mods for now, as you say they'll screw your insurance.

minispares stg1: erm cant find it on the website

or do what I did and make your own!

I have a piper cross pancake type airfilter, I'm actually using the original 998 needle but have had it filed so is runs smoothly, mini spares inlet manifold, maniflow lcb exhaust manifold, Rc-40 Center pipe with silencer and a peco twin exit back box

it sounds nice and I could really tell the difference when I put it on and had the RR session, I even keep up with most people and I think southy will vouch for us as he doesn't mind following me goin' places!

Insurance wise i don't think you'll be looking at that much extra, some company's may not charge extra. Shopping around is the name of the game!

agreed. plus any mods are a waste of time if the engine isnt running right.

an induction kit is basicly a non standard air filter. the main aim of them is to offer as little resistance to the air as possible. thats just a bob standard filter replacement, other kits have pipes that move the air filter closer to a source of cold air, usually near the front grill.
the theory behind this is the colder the air is the more dense it is, therefore the more oxygen enters the fuel mix.
they also replace the factory fitted air intake and aim to provide a smoother flow of air, again its all to to with fuel mix.

on modern cars they work very well, however on minis they dont. many people fit cone filters to the carb in place of the air box. there are rolling road results proving this reduces the power a little. the best results came from a standard air box with extra holes drilled and a k&n filter fitted. there is a topic on here somewhere i read a while back, a search may bring it up.

its also advisable to modify the exhaust, if air can get in faster it also needs to get out faster.
which is where the stage 1 kit john mentioned comes in.
