My Stock Bf Mkii Xr6t Stock Run 13.6@167kph

[Turbo6man]

Thanks, but you better believe it, the car was absolutely stock.

RWKW's don't always equate to track times. The shorter 1st and 2nd gear in the ZF help enormously.

There is another BF with ZF that ran a 13.70 stock as well, it's not much a freak.

Not to blow my own trumpet, but I am not a bad driver. I do hold the NA6 record on AFF, so I do know how to race. Ask Mark (Spoolman) on AFF, he will vouch for my integrity.

I don't doubt that you believe it is stock. And I don't doubt the time. Nor do I question your ability - the times show you can drive no worries. But the trap figures don't add up. Stock cars do a max of 100 mph trap speed and with the times varying from low 14s to high 13s. Any way you look at it you have a good one so well done.

PS. If you check the times published in threads elsewhere you will find that 230 rwkW is about the minimum anyone has ever run similar figures to yours. And at the other end of the scale some cars even with more than 260rwkW have achieved similar. (Which is why, at my first guess, I estimated your car may have around the 240 -250).

Look no worries or anything, I was a bit surprised as well, the best I was hoping for was perhaps a 13.7 or 13.8 .

It was a ex-Ford executive car, I got it the Saturday last week, it's as stock as.

Just because of the time it ran, doesn't mean that it has 240rwkw, I would estimate perhaps around the 195-200rwkw mark. Dyno's never tell the real story, they are only a tuning tool really.

My NA6 had 164rwkw when it ran a 13.75@102mph, there were lots of other cars with better dyno figures than me, but not many came close to my times on the track. A lot depends on how you get that power to the ground, my driveline was the deciding factor, 4.11 diff and 3000rpm hi-stall (which took 14rwkw off my dyno figure) and slicks.

I think you are trying to compare it to BA's 4 speeds, the ZF box is so superior you can't.

There is a BF ZF6 NA XR6 on AFF that has run a 14.20 @ 99.50mph with just headers, exhaust, typhoon intake and underdrive, that's it, and it's UNTUNED! Once he gets it tuned it will probably break my NA record.

Simon's (Xtreme) "Project BF" ran a 12.5 with tune only and 255 rwkw

I ran 12.7@112.5 with 262 rwkw. On the same night, Thundabird ran 13.0 with a BPT custom generic tune only.

Therefore I think your times and trap speed are entirely feasible for a "fit" and well driven stock BF auto.

Well Done!

Wow! That's some amazing times run there with just a tune.

I will have to get me one of them.

And thanks for your input.

I got 101mph with a stock ba, surely 104 isnt out of the question in a bf auto?

Considering stock auto F6's have run 108-109 mph I think doostars 13.6 @ 104 is legit

Doogstar are u doing the 2-1 launch???

No, I didn't know about the 2-1 launch till later on, only stalled it to about 1600rpm.

That run was just in Performance mode, the ZF will change at 6000rpm at WOT.

I will try manually change next time at Heathcote, last week was just to get used to the car.

[Vevapower]

I heard that the ZF spoiled the party some how when trying to stall it up?

Has anyone had any issues with there's, say stalling up to 2000rpm?

Going to WSID in about 2 or 3 weeks to see if I can crack a 12 or cop a massive "I told you so off my brother".

Also anyone with some tips for a 1st time drager (never done it legally) would be welcomed with open arms.

Guys I really need to crack these 12's.

specs again: 06 BF 6 ZF 255 rwkw's

My TT has the 6 speed and by shifting manually I managed to chop almost half a second off my time.

If you stall up over 1500rpm I found it had adverse effects and slowed me up. For me at least, 1500 was the sweet spot.

Don't floor it as you change gears - stall up, slam it back into 1st, then floor it. If you do it simultaneously, it's no good.

I got my best time 13.5 and fastest top end 165km/h when shifting at 5000, which changes it over at about 6000. Shift after 5000 and you're not helping yourself - I hit the limiter twice, as you can't hear a thing and must keep your eye on the tacho.

Good luck.

Thanks for the tips, especially your explanation of the 2-1 launch. I will put it into action at Heathcote where I can get some practice runs.

I haven't had much experience yet with the 6 speed yet, but the 4 speed I know pretty well. I think where you change should depend upon where you are making your peak power, the perfect change should be just after your peak power so it stays in your powerband after the gear change. A dyno readout should give you a good idea of where your powerband is.

However I have found that the 1-2 change should be about 5000 to 5500rpm, as you want to get the car into the higher gears as soon as possible, probably change at 5700rpm in a ZF for the 2-3 change, but I would hold it to 6000rpm if you have to do the 3-4 change. I used to do the 2-3 change at 6,200 in my NA.

Anyway, that's only my theory, I will let you know when I get to test it out. I will try your shift points as well.
