At least we all agree on 2 things. That flamer kits are a waste of time and that flames should be left to cars that can make them without the use of an additional spark plug :) Nick: You are correct in what you say with the exception of the dump valve part. When on full boost (say 1 bar for...

Also a wastegate does not alow charge into the exhaust - more accuratley, it only puts into the exhaust what was on its way there anyway. The only difference is that it bypasses the turbos turbine housing instead of going through it. Dump valves do not alow charge into the exhaust either. They...

Flames Kits: Flamer kits (in my opinion) are just a crap product for the Max Power generation. A spark plug is fixed into the tailpipe and I think an injector goes there too. Once switched on, the injector and spark plug make flames. What a stupid idea - anyone can make a fire with the three...

I phoned R-Sport the other day and the Renault team are not back until 2nd Jan 2003. Ill speak to them then or soon after and get to the bottom of how long mods are likely to take. They are only about 1/2 hours drive away from me so Ill let you all know when I have found anything out. Laurence

I think it looks great myself (although a bugger to clean)!

Performance leads and plugs make no difference whatsoever to performance or power. All you gain is reliability as the plugs/leads are likely to last longer. Some people have experienced gains with fitting new plugs, but this is because the engine has been extensivley modified and requires a...

The reason 4th gear is the most accurate is because it is the closest to a 1:1 ratio, meaning the ramp rate doesnt need much altering (which can produce some funny results in itself).

Adam: Totally agree with you mate. I know the 172 is a great car. I own one myself so nothing I would say about is is intended as a detrimental comment, but an EVO anything is beyone comparison. The accelleration is devastating, the traction (both off the line and cornering) is superb, and I...

If you have really driven an EVO and you really are THE STIG then you would know where the intercooler spray button is wouldnt you? So come on Stig...where is it? :D

weyland - The octane level has nothing to do with how clean the fuel is. Optimax boasts cleaning additives (which DO work) but the octane level represents the fuels resistance to preignition and nothing else. 97 RON is fine for a 172, and Optimax is better because it is 98.6 RON (on average)...

Yes you can but you may experience Knocking (or detonation) when you get high up the revs. I have not tried it myself, but Im pretty sure it wont be any good for the engine since the engine management is mapped around 98 RON. The car is equipped with knock sensors, but I wouldnt really put the...

Viceroy - where do you live then? The only place I know that will sell you 93 octane is America. However 93 is a MON rating, not RON like in England.

There is a grommet under the glove compartment that just about everyone uses. Search back through previous posts for more info...

Have I missed something here? Is traction control fitted to 172s as standard?

Ben j: That wasnt aimed at you. I was just stating it doesnt stop at a supercharger for the benefit of anyone thinking about undertaking this sort of project. :D

It isnt as simple as "Throw in a supercharger!" Injectors with a higher flow rate will be required, then a new ECU (because the standard engine management will not have sufficient load sites to cope with positive pressure). About 4 hours on the rollers will see it running right. So now it...

The best one is when he tells Vin that a guy came in to buy 3 T-66 turbos and MoTeC exhausts. Only thing is - MoTeC dont make exhausts! Great film though.

Check all your fuses mate - Ill bet its the fuse with the picture of the Head Unit that has blown. This happened to me in my old Clio and stopped the remote wire from sending a voltage. The fuse you are interested in is on the end of the dash (near side) so you just open the passenger door.

Chris - Very impressive mate. I think theyll have to have my Cup for a day after seeing those results. "Dear Father Christmas..." LOL! Paddy - The graph shows predicted flywheel horsepower based on the rolling resistance measured on the run-down - these rollers are pretty accurate and you...

Totally agree with TB1. More power through thrashing is no more than pub talk. The idea is to let everything bed in gradually. You didnt try for your 1000 metre badge on your first swimming lesson did you? Gradual increments to your self-imposed rev limit as the miles go on is my way of doing...
