nybody relocated their oil filter on a 172? considering doing this for convenience and to make it easier to fit TBs. Also, the adaptor can carry an oil temp/pressure sensor to feed info to a new gauge on cockpit. badly missing on 172s. While were on the subject, anybody fit a scavenge pump...

piper cams have a moderate road profile cam, nothing too wild, 265 degrees or so and about 10mm lift. Claimed 12 hp increase 1500-6500 rpm range. Or slightly more agressive cams at 286 degrees, 12mm lift and 2500-7000 rpm range. Views?

I need the measurement of the diameter of the black elbow hose that connects the airbox to the throttle body. Looks like 10cm each end and I dont fancy disconnecting my bmc to measure up. Anybody done this recently and measured the hose diameter, or even better anybody replaced it with a shorter...

who had some fitted on a 172/cup? How much and where please. Thanks, P

Hi, thought Id post this for info for any track day plans: most track days restrict noise to 100-105 dBA measured 0.5m from the car at 2 thirds of max revs. Some also do drive past measurements obviously further away for induction noise etc. On some "quiet day" events like goodwood, limit can be...

anybody with pictures, diagrams and measurements on the F4R head, inlet/outlet, valve seat details etc. Thanks, Philip

other than always benchmarking improvements on the same RR (and thats impossible in my countrywide chase for decent mods), what is the most reliable way to compare power after mods. Obviously the only true measurement is bhp/torque at the wheels, but even that will fluctuate from RR to RR. is...

Came back from Owen developments yesterday with Unichip fitted. 10 bhp gained (well to be precise 9.7) and a useful 6.6 lbft of torque nicely flattened the torque curve too. Top end acceleration has improved from 5.5k rpm and max power is at 6431 rpm. Measurements were done at 31 degrees...

Any tips on getting an FIA approved 3 or 4 point harness (Sparco, Sabelt) at a reasonable price? Cheers, P

anybody figured out a way to effectively fit a 4 point harness while keeping the standard seat in my cup? Need the harness for practical reasons, dont need the race seat look for equally practical reasons..

Been experimenting with my standard Contis. Went up to 35/33 front rear and the car is too fidgety. Currently running on 33/32 and seems ok, although I can get induce oversteer more easily with 33 on the rear. Havent tried 33/32 in the wet yet. wat pressures are you running on your cars?

Has anybody tried fitting a shorter hose between the TB and the airbox on a Mk2172/cup in order to get more room to properly fit an IK. The standard hose looks like it could lose about an inch? Also, anybody tried relocating some of the radiator hoses that are in the way if you try to drop an...

I believe that some earlier 172s had an alloy/aluminium bonnet instead of the steel bonnet on the later cars. Does anybody know about this, as it would be a good way to reduce weight (7-8Kg) as the current bonnet weighs a ton.

thats the noise Im getting from behind my dash board every time I rev past 3000, very noticeable at 5000. It sounds like its coming from behind the dash somewhere between the tweeter and the air vent. I removed the light level adjustment panel to have a look behind the dash to see if anything...

when I got my cup on Friday, I went for a long drive etc until the petrol gauge was down to the last notch, even though the trip computer was still showing 120+ miles to filling up. I filled up the tank but only got in 30 litres or so. Also, having filled up, the gauge is already two notches...

Got my cup today, bought it as a demonstrator with 3k miles. I added another 250. First impressions: I love the suspension and had great fun with the torque steer. Its deceptively easy to bounce it off the rev limiter and it took me 30 minutes to get used to the right Rev pitch to change up at...

Im booked to have a cat-back exhaust from KTR and David told me they are now substantially quieter as they have fitted new baffles etc. I was going to go for Magnex at first until they said theye didnt have a cat-back for a 172Mk2 or cup. I am still a bit concerned that the "quiet" K-tec is...

anybody come across an interior car fan that can be attached to the inside of a window, solar powered and will extract heat from the interior of the car when parked in the sun for long periods. Ive seen them advertised many times but cant remember where. Also, anybody come up with an aircon that...

how would you get a "quality" precision-engineered sound from a 172/cup? by that I mean a nice metallic businesslike race style sound instead of the usual boy racer booming exhaust sound. A mixture of 911 aircooled engine, crisp induction noise, etc: something with less bark and more bite ...:D

See http://www.alpinerenault.com/frindex.php3?page=bienvenue/frbienvenuehttp://www.alpinerenault.com/frindex.php3?page=bienvenue/frbienvenue the r-sport factory in dieppe is working on a turbo 2.0 16v megane pushing 230 bhp for release in Sept. 2003. How likely is it to retrofit the turbo setup...

Is there a new clio coming out in 2003/04? Ive seen references to this in several articles and reviews, but no actual details. Im taking delivery of a cup in a month and Id hate to see a new model launched the same year. Any info? Cheers, P

I assume the airbox on the cup is the same as on the Mk2 172. Where does the pipe that feeds it cold air connect to: the front spoiler? Has anybody thought about moving the battery (group N style) elsewhere in the car to make some space for a proper airbox and ducting assembly? Ive read a lot of...
