wow... this thread is really picking up isn;t it?
i believe its quite possible for a street car (i'm assuming we're talking vtec here, since almost everyone here is in a honda) to do the same sort of time as an MME race car, keep in mind that you will need to compromise a fair bit (rule of thumb, a street car will never be a race car..a race car will never be a street car). the simple fact is that MME cars are all built to comply with a mix of group N and super production class cars.. so they have to run a fair bit of stock parts such as the throttle body and the stock airbox. they are also limited to tyre size and brand. most MME 1.6 class cars make 170hp at the wheels to ensure it can last the 12 hours..
a 1.8 litre makes 200 at the wheels with cams and a computer... all you need to make up for is the weight and the tyres.. i'm sure some of you already have stripped out interiors... if you can get the weight of the car to about 1060kg with driver and a half tank of gas you have pretty good chances in doing that lap time(again other factors are involved.. correct gear ratios, final drive, correct rim offset, good DOT approved tyres).
tecque: tyre pressures are dependant on the actual day itself.. but the aim of the excercise is to get the pressures to run in the 2-2.2bar range after you've done a hard lap, again this is also dependant on your tyres. on a day when the track temp is about 45 degrees (very common in sepang) i'd set them at 1.4 front and 1.6 rear on silverstone T5 slicks and with nitrogen in them.
jamesweh: most cars have that understeering problem with turn 5 and 6. but i think its more of a set up problem than a racing line one. 150km in a gti in turn 5 and 6?? thats darn pretty fast.. we're only doing 130+ in our EK...
