Whincup Supercar Runs 10.84 @ 134 Mph

[XRDOSE]

that's fkn awesome

I know they're N/A v8s but are they stroked? cammed? they surely can't be 5.4L, can they?

Im no expert on V8's but arent they the 5.0L? as are the holdens for parity

[fordboy1981]

they're 302 windsors... nothing to do with the 5.4 modular V8...

Expensive Daewoo use a 307 chev.

they weight limit is 1350kg. I'm guessing you would expect around 400rwkw...

its a novelty if anything.

great to see them mixing it up in different enviroments though.

I hope you guys also know that there engines are limited to a 10:1 compression ratio and a max of just a messily 6 degrees ignition timing...

.....and that the valvetrains are stripped and rebuilt/replaced every 1500kms and engines freshened up every 3000kms. They are not exactly tractable below 2500rpm and would not pass any semblance of an emmission or sound test. Add in that the cars are gutted and weight 1350kg, and you can see how that measly little 5L is not doing it so tough after all.

Full credit to any N/A 5L running a 10.8 @ 134, but all of the above teamed with a sequential manual and full spool rear end ensures that the racecar performs as you would expect.

Who told you they only run 6 degrees of timing max?

Jamie Whincup up against Craig Lowndes – now this pair of competitors from the V8 Supercars Kingdom are running their full race cars. Whincup, this is his first visit to Willowbank and during an on track interview he was saying he was absolutely blown away by drag racing, Lowndes who has been here before is totally enjoying his Winternationals Experience. They certainly sound like V8 Supercars, they are on the limiters, as they leave the line, they stall it Whincup recovers first, Lowndes wouldn’t even qualify for the street bracket, but Whincup would just make it.

Whincup and Lowndes again, now look Whincup has decided for the big tyre smoking burnout, Lowndes just a short water burnout, Whincup is out, he is running a fantastic pass, but Lowndes stalls it off the start line and yet again wouldn’t make it into super street. Whincup would now be in Super Sedan.

We have strong burnouts in both lanes from these V 8 Supercar competitors, Lowndes has opted for the opposite lane this time, and Whincup he wholeshots Lowndes both of these cars would now qualify for Super Sedan.

Who told you they only run 6 degrees of timing max?

Daniel

Its in there regs and Paul Morris told me it about after Mark Winterbottom's qualifying time at Indy a few years ago was disqualified because his car briefly exceeded the maximum 6 degrees ignition timing rule.

Another useless bit of info is that all the major engine components like crank, rods, pistons, flywheel etc have a minimum weight rule that they must be above...

Ok, it didnt seem right (the cars only having 6 degrees ignition timing) it is actually 6 degrees of VARIANCE that is the rule:

An extract from the Season 2009 operations manual:

14.2.4 The ignition timing of any engine must not vary by more than six (6) degrees while the engine is above 4,000 rpm and above 10 percent (10%) throttle opening.

In other words, if at 4001rpm and 11% throttle you had 18 degrees of timing, at any point up to either 7500rpm and/or 100% throttle, you would be limited to a maximum of 24 degrees of timing.

ive seen a few different runs and it always looke like one of them stuffs up the start yet the timeslip shows them to be within 0.05sec of each other. Does anyone know how many runs they did?

they did three runs but on the last run lowndes ran the quickest time of the day but he missed the start left about .1 later than whincup

so he ran faster but still lost

considering how loud the v8s are at QR every year it was kinda funny that compared to everything else running they sounded like two stock xr8s sitting on the line couldnt even hear em really

BTW their runs looked really slow compared to the nitro funny cars that ran straight after em (4.99!!!!!)
