Stock XR8 - 13.71 @ WSID

[prdreilly]

Took my BF XR8 auto to WSID last night and came back pretty impressed.

First run was a 14.641, too much wheelspin by loading up the torque converter. But I did manage to reach 165.19km/h.

Second run, I took out the air filter, and didn't load up the torque converter at all, just brake off and accelerate.

60' - 2.159
330' - 4.986
660' - 8.949
ET - 13.710
Mph - 101.92
Km/h - 164.03

This is a car with standard exhaust, standard road tyres, spare wheel and jack on board, plus two baby seats in the back and I even had 3/4 of a tank of normal unleaded fuel, but a pretty light driver at 57kg.

What is the quickest stock time you have heard of for an XR8?

Timesheet for both runs attached

Thats pretty impressive. Motor and Wheels usually say the xr8 does like 14.6. and they say the typhoon does 13.6, so your 8's as fast as a typhoon. or wheels are full of it.

Just looked up the back of my latest Wheels mag and they have 14.4. (6spd auto)

Motor magazine has 14.0. (Doesn't say whether it's auto or manual)

From memory, Wheels test times are half a tank of fuel and two people on board.

The only other variables I can think of are:
1. That the Drag strip has better grip for a quicker time, or...
2. That a car with 50000km has a freer engine than a fairly new one that the journo's often test.

Thats a manuel for Motors time.

Wheels usually have a second passenger a full tank of fuel for their 400m tests.

also as one of the car mags has stated, drag strips tend to give a faster time due to its radar system (or something along those lines?) where as the way they (mag) test it with the on board computer, its more accurate.

Stop ya cracking me up, more accurate my ***.


Oh and well done awsome time for a stocker.

drag strips dont use a radar,

and there is no way a mag on board computer is more accurate

put this in the drag section u might get more info on times

[Grum]

nice run, have a look in the bseries section and on www.bseries.com.au

Mate that is very impressive!

[BAGTP454]

you are 56 kilo! that's light. Impressing time mate.

well wouldn't the onboard computer version actually count wheel spin as going some distance?

dont actually know how the onboard computer measures the time

A drag strip starts to measure time when the timing light is tripped, which is 60cm past the second staging beam. You can already be doing 5km/h by then! That means you are already moving by the time the timing system starts counting away. Secondly, some strips measure the terminal speeds in the 60 feet up to the finish line, whereas others measure it for 60 feet after, hence you can get different terminal speeds.
The mags use a hitech gadget that is very accurate (despite some claims otherwise) called a v box or something or other. Anyhow, they work as soon as the vehicle starts to move, then measures g forces etc until 400m exactly and gives a terminal speed at the exact time you get to 400m. I think they use sat nav from memory.
Either way, the mags tend to be around 2 to 4 tenths slower over the quarter mile because of these differences. The final difference comes from traction - and drag strips have heaps more than the road.

That's a great time though!

[Grechie]

that is defently impressive, congrats !!

[XR8-260]

Great time mate. Just goes to show that stalling it up is not always a good idea especially when you don't have traction. I'll keep that in mind when I hit the track myself.

[JAYBA]

very quick time...

have seen high 13's out of stock manuals, motor has recorded
a 13.9 out of a manual

and have heard of high 13's out of the 6sp auto but never a 13.7

well done good start for some bolt ons and some 12's

[Stav]

Well done.Must be happy with that.

[hot460]

Thats a great time from a stock car. My old BF did 14.00 with 1500 klms on the clock. Got to love the 6speed autos. 13.7 is awesome.

[FPV8U]

Thats an awesome time!

Great effort mate.

[XRCIST]

Sensational!!!!!!!!!! Definitely more left in it considering you didnt stall it up and the extra weight you mentioned.

[Falc'man]

Well done mate thats a ripper time for a stocky. Very good potential... any plans for it? LOL we've got all the freaks here in Sydney by the look of it.

I only bought the car with the intention of keeping it for a year, so won't go down the mod's road, since I will probably only keep it till about October or to the beginning of 2008.

It was an ex NSW highway patrol car that I bought at auction with 38000km on it (didn't want to say that, because the whole are they chipped arguement will start up again.)

I would be ecstatic if I could just go 2 hundreths of a second faster and get a 13.69.

[Polyal]

Its all the ZF. Hell even 3v's feel quickish in stock form with a ZF.

Nice time. Planning to see if it can be backed up?

It is an impressive gearbox, so quick to change and so smooth even at full throttle.

I'll have another go soon, to see if it was just a freak time, or if I can just find those other 2 hundreths of a second.

It will be interesting to see if a lighter fuel load makes for a quicker time, or just results in more wheelspin with less weight being over the back wheels?

imagine premium fuel !!!!!!!!!!!!!

I missed that, on 91 that is awesome time, but very impressive MPH for that fuel.

[MYLO_XR6]

57kgs!!! skinny k*nt!

how bout u drive mine to break into the mid 13's...im now 106kg!

thas an awesome time! congratulations!

[SpoolMan]

Congrats on the time, we are not seeing to many BF Boss powered cars hit the track, at our last drag meet BF XR8 CAI with edit and CAI went 13.4.
The 6 speed has lifted these cars, would be nice to see some BF GT's run...... the BA boys flogged there Boss cars from pillar to post...
Do you have plans for any mods?

How well you know us Mark! And, yes a great time from a stock XR8. There are so many more inexpensive bolt on mods that will get you into a 12, just ask HOT460......
