Hi guys, the cup engine (in the racers) is a sealed bog standard 172. the ecu is different, and the exhaust. However, the power is only marginally increased. the 0-100 is down to the sequential manual box and the lack of weight. but to get a public cup to this weight would mean...

Hiya Slayer m8 ! re your theory. chipping a forced induction car can increase both torque and bhp.. due to the equation, (BHP=Torque * rpm) / 5250, as the torque increase, so does the bhp. the interesting part is where the bhp is rising rapidly, but the torque os decreasing - as seen...

Hi, Hopefully nick will reply, otherwise ring him. they are superb !.. you cannot set them up yourself as the fuelling needs adjusting at top end WOT. Nick has this sorted now.. Joe.

Lol Craggs... I only know of one turbo mod for the clio 172 / cup at the mo.... One for the cup will be at a local reno dealer.. but it wont come from reno lol. - might come from a bit nearer to home Joe.

Ben M8 ! a stobe would give you ignition timing not that of the cam. actually ... I INTEND to use a strobe to see cam timing changes.. If you put no. 1 in overlap tdc... paint a line across the cam wheels, then run on the rollers (You would have to drill a hole in the cam cover to see...

Sandy.. which turbo mod do you refer to for the cup ???.. Joe

Jilly, .. .........

Tim, correct .. !! but I still say you can have your cake n eat it... buy an import 172... put the grand to grand an half in the teapot.. then wait a few months.. when its all run in and you are happy, spend the dosh on whatever you want.. cams, exhaust, ecu mods etc etc.. you...

Hi Tony, sorry m8, I disagree, the term adaptive has jack to do with the driver.. it DOES NOT adopt to a driver or style. it adapts to lama signal and knock based on other inputs.. ATS, CTS, etc.. Fueling is simply a case of advance till ya knock, then back off. this is a total old...

Hi Pugboy.. A slarty ?? Hitch-hikers guide to the galaxy et al Joe.

lol at Ben... bet it was the engine management.. !!! Chavvy, indeed, renault ARE working on an electromagnetic valve train, and you are correct, it would make all sorts of things possible.. Now, I have just done the test with the engine at idle, hooked up 12volts to the solenoid.. and...

lol Ben, thanks for the kind words, but I am a mere novice to some of those guys. Have you got Daves engine management book.. that is soooooo good to read.. Joe

Hi MC.. please DO ask questions and offer coments m8.. !! Its how I learn too.. You may well come up with something I havent considered. Ben, m8, yes, the andvance in this case is theoretically a case of the inlet valve opening being further up the cam lobe ramp at tdc (hence inlet opening...

Hi Ben n Mc. MC, we have tested it with indcator lights to show powering of the phase shift actuator so I am convinced this is how it is desgined. , it is not in operation at idle.. the cam is retarded (in relationship to the exhaust cam - not overall note.. ie - there is no vvt at all on the...

Tim (Lennox) Of course anybody who bought a cup could have bought a real 172, but this is a car for hardcore enthusiasts and its limited unlike the standard 172. Upgrades only available for the 500 production cup cars - its like a special thankyou for helping Renault back to the rallying...

must agree Pugboy.. abs is not a luxury nowadays.. it is essential... Joe.

let me word it another way Ben.. vvt is not active at idle.. its purpose is to advance the cam above idle. disabling the system causes the cam NOT to advance at all. thats the key.. the lack of advance makes no difference.. so whats the point of even having it ?? Joe.

Hi Ben.. the system advances the intake cam by about 5-15 degrees.. What I am saying is that, if you disconenct the system, the cam will not advance... - it is effectively retarded at idle. - However, the lack of advance makes Sod All difference to performance. the 1200 rpm is the...

more tests have been done (by a well known reno specialist ) to confirm what I summised earlier.. ap22 standing 1/4 15.9 - vvt enabled. 15.9 - vvt disabled.. me thinks mr reno just wanted to put vvt on the brochures.. Joe.
