The cam wouldn't make any extra power you need true aftermarket ones.
Best modification value wise is to strip it and coilover it. OR get a 172 engine grarbox suspension brakes etc for £1.5k + vat from j3ned on here.
Pm BenR about a cam, also proting and polishing will help you aout, but for casm and porting and polishing you are looking at around £800, you have to ask yourself, is it realy worth it on a 1.4?
Yup, i have a range of cams available for most renaults.
One of my new design cams pushed 181lbs.ft at 4500rpm on a 172 about 2 weeks ago, only 2 sets running around in the country at the moment. Are prooving to work extreemly well.
A chnage of cam to get the full gains will require a remap to up the fueling and this is easy to spot from insurers points of view even these supposed hidden ones arn't hidden insurers are wise to this way of geting hidden extra hp etc and they check these now as if they don't have to pay out for a calim as your cars modified then they will do its a cutthroat industry anything to save some money.
If you cannot afford the premium I just won't do it you can go faster in a car just by learning to drive better and take better lines etc plus insurance companies cannot refuse claim jsut because your better at controlling a car.
so no one does cams then? is that correct that apart from BenR has done do those 2
cars that no one has them.?
if so benr would it be possible to see a power graph of one please? and how much to have one fitted on a 172cup and do you use standard timing tool/marks?
would be very grateful for your help.
Cams for the F4R are ground to specific timing lications relative to the cam alignment tools used as you cannot dial in a F4R cam in the traditional manner due to the cam bearings being part of the cam cover.....which is a pain, so you just have to grind them perfect straight off.
PM me for price please.
I will get graphs up in a while, got to have dinner.
