ive tried a few differents things but i think putting a set of 15 inch alloys on it has slowed it down dramatically anyone got any ideas how to get my speed back without taking off the alloys ?

An air filter change and a good service may sort it out for you mate, or upgrade the air filter and a new exhaust system so there is less restriction for it.

And welcome to FOC

K&N will make a difference yeah cause it increases the amount of air that flows into the car, and when theres more air the car requires more fuel meanin u get more power, although the other alternative is to try a mod chip in which goes on the air intake sensor, it sets it to a default so it takes in more air then it needs which does the same as above but increases ur bhp more

ah rite well yeah ur best bet is to go for the performance air filter

[vinnyvangough]

Yea go for the air filter and the exhaust. Should free up a bit more power by allowing it to breathe a little better

hold on u know you said that having 15" alloys on it has slowed it down, are you sure that is hasn't just knocked your speedo, because when you put bigger wheels on the speed ometer shows that your going slower then what it says, for example it says 30mph when ur really doin 25, that might be what your thinkin of when you think its goin slower

[racey]

make sure if you put your air filter on that you change for a better exhaust because you can end up spending loads on a filter haveing 1 or 2 more brake but if you upgrade the exhaust youl het more power becasue the exhaust air will have somewhere to escape or youll put preasure on your stock exhaust

You could try fitting a porsche engine to it but seriously your speedy could and probably is now reading incorrect due to the change of wheel size!

[andyroo89]

could try fitting a 1.4/1.6 cvh exhaust, because of the increase of the bore.
or twin barrel carb from later model.. instead of single barrel.
also ive seen a camshaft kit available on ebay may only be for electronic ignition though.
otherwise some NOS octane booster/engine cleaner available from halfords and a good rag should see a couple more horses

really depends how much you want to spend but id say simple just get the octane booster and a double barrel carb from a scrappy!

[mintalkin]

basically you need to get more air in and out so any thing on induction or exhaust is going to help, even go for high lift cam and ported manifolds depends what you want to spend

cheers all ill av to chek my speedo wit a sat nav and will try all the other bits shud be gettin money sooon well payed fri thanks for advice:)

yeah ur speedo can go 5% each way from being accurate, where as the sat-nav is 100% accurate, thats why if u get pulled over be te police sayin that ur speedin for example 34mph in a 30 zone and ur sat-nav says that the highest speed you'v done is 30mph then they havnt got a leg to stand on when it comes down to gettin u nicked
