yeah, on modern cars, cold air induction feeds dont do much unless coupled with high flow exhausts and remaps, but the late 80s and early 90s hot hatches which had much simpler engines seemed to benefit much mor from cold air feed induction. you can actually get upto 50% power increase from...

you only want to increase the diamiter of the intake pipe if you are also fitting a high flow exhaust system and remapping it otherwise you will loose engine compression and therefore power as the motor cannot suck air in any fater if it cant exhaust it any faster

that is very dependent on the engine. you cant just claim a remap will give more than 10bhp on any modern car, this simply is not true. remap gains can only be accurately predicted in terms of %increase on standard power. for example if you remapped a na petrol engine with 90hp standard you...

if there is space behind the radiator grill to run a pipe, i would do it there, if not, cut a hole in the grill below the reg plate, but as high up in it as you can, any lower on the front of the car (fog ligh level) and you risk sucking up water if you hit any puddles.... or just be very...

ok well if your doing it, fabricate a cold air feed pipe and route it through the bumper, and try to move the cone to a lower cooler part of the engine bay by extending the ducting from inlet manifold to cone. dont forget to put a good gauze/mesh over the opening of the cold air feed so you...

dont have any evidence except my own experience, but that was 10 years ago on a renauult clio 1.8 16valve, and i did have the dyno run print out which showed 137bhp before and 143bhp after fitting an appollo cold air induction kit with cold air feed cut into the bumper, so compleately un heated...

ok that makes sense then as the mpg went through the floor so must have been in regen then. thanks

ok thanks mate

ok thanks for the advice mate, will pick some up then. ps shell vpower is only 97 ron, but tesco petrol stations (not esso) sell higher octane fuel that is 99 ron, so much better and cheaper than shell v power, you will notice even better throttle response over shell v power too. thats all i...

sorry i just joined, just wrote a really long response and then the site sai it could not be submitted! the long and short of it was, that for the work you will do and the quality of materials you will need to actually insulate the cone filter, you will prob end up spending 100 quid and a good...

Hi, i know from experience and expert advice that any fuel system cleaning additive for petrol cars does make them run smoother and more efficiently, but they also strip out essensial oil and lubrication in the process which is essensial for fuel pump, injector and valve health.... in the long...

Hi everyone, i am a dedicated petrol head and have always had large capacity 5,6 and 8 cylinder na vehicles, i have just done the dreaded thing and bought my first diesel, and having read about the regen mode the dpf filter goes into when needed, i was wondering if the extra heat and lack of...
