So I decided to run some practice laps in a handful of cars I had in my garage, the cars themselves are somewhat out of tune (ba dum tisch?
) like I brought them for certain events and just threw random mods at them. For the purposes of the tests I was aiming for 1300kg and 550pp so I threw on some weight reduction and various power mods and fiddled with the power limiter until I got there, some had full suspensions and wings, some had the cheap suspensions and no wing, a couple even had just about every possible addon you can buy and all cars were running Racing: Soft tires.
So take these numbers with the proverbial grain of salt as there's likely a lot of tuning to be done and driving skill improvement that will garner better times.
TVR Tuscan Speed 6 - 1300kg, 558hp, 548PP -
1'05.4xxHas potential, even suffered from some understeer but had full +200kg ballast.
Chevrolet Camaro '10 - 1318kg, 493hp, 550PP -
1'05.2xxSurprising car, has most mods including aero, needs a little tuning.
Lamborghini Murcielago - 1350kg, 512hp, 550PP -
1'09.xxxHad aero parts but comedy oversteer on banked turns, needs suspension + tuning, didn't get a good lap.
Lamborghini Gallardo - 1360kg, 500hp, 550PP -
1'05.2xxHad aero + some mods, slight understeer at times, quick on the straights, solid car.
Ferrari F430 Scuderia - 1350kg, 487hp, 550PP -
1'05.9xxHad some aero parts, needs tuning (possibly suspension).
Ferrari F430 - 1334kg, 493hp, 550PP -
1'05.6xxNeeds some mods + tuning.
Chevrolet Corvette ZR1 (C6) - 1357kg, 485hp, 550PP -
1'05.056Almost no mods, could benefit from suspension + tuning, solid car.
Ford GT - 1334kg, 447hp, 550PP -
1'04.3xxNeeds a suspension, possibly LSD, surprisingly nimble, solid car.
Lotus Esprit V8 - 1300kg, 545hp, 547PP -
1'05.1xxHad most mods but may need ridiculous wing, needs tuning.
Like I say, these are just rough numbers and the cars I tested weren't modded to an even level (beyond the weight / pp targets) so there's plenty of room for improvement and I'm sure I could've probably got better times if I'd done more laps with each car even without tuning.
I do think that 1300kg and 550PP are good numbers though and while there are tons more cars to look at I'm tempted to suggest a 550hp limit too. I know the Lotus Esprit maxed out at 545hp and the TVR Tuscan Speed 6 at 558hp with all the power mods yet both came in just under the 550pp limit, so there may be some other cars that might come in with even more power but not break 550PP.
Food for thought
