MPG and air filter setups

[Ricardos]

Yesterday i fitted the Espace V6 airbox and ran a 102mm diameter feed from the outlet to the passenger foglight. With the old air filter induction i's on average over the last 2 years see 37-39MPG, pure motorway driving would give me 44-45MPG.

I tripped the meter before heading to work and in the 10 miles of driving it was showing 55MPG! Now in the 2 1/2 ears i've owned the Clio i've never gone over 46MPG, this must show that now i'm directing fresh, cold air to the filter instead of sucking up hot air from the engine bay. I just wondered if anyone noticed or paid any attention to their MPG?

By the time i whipped out the mobile phone to take a piccy it dropped to 54 lol, this figure was driving at 60mph in an ambient temp of 0 degrees over 6 miles of dual carriageway. Since this morning it's dropped to 48 average in traffic, 30mph, standstill....... I expect it to be lower of course, but on a decent motorway haul with ths setup there's no reason why it shouldn't give me at least 50MPG

As per the other thread mate im sure JMS proved this is one of the worst places to get forced air induction from, I know when I had the same setup I made sweet fa on the rollers.

I'll look into moving it to the grill area, out of interest as i've never seen the OE Clio 172 setup where does the pipework run from, even better is there any pics knocking about of it. I'm all ears for making sure things are done right
