F6_tornado Runs Bf Auto At Kwinana

[geea]

F6_Tornado, with his new BF F6 AUTO UTE ran down at the plex tonight.

Mods are: Injectors, Dump pipe + Twin cats thru to twin pipes and Edit.

Barry Batten tuned to just under 300rwkw, with afr's in the 11.8's. ( See M6XR6Ts' thread for dyno graph )

Time:

  12.60 @ 111mph.

Just drove up to the line, plonked it in 'D' and took off.

Nice effort from a very concervative tune, and small amount of mods.

Car has less than 500km on it.

Well done Gramps.

The times aren't very good for 300rwkw's and the mph isn't really there either. he time could be slow due to a bad launch but the mph should still be there.

I know both Dvae and Rob ran 11.5/11.6 with similar power and both were around 120mph.

One thing to remember though, we don't race with the same setup as yourself; running front runners, slicks, suspensions mods etc.

This car run stock wheels and tyres, stock suspension and was the first pass done in it.

I don't think your car ran 11.5/11.6 the first time you took it down.

I'm sure the rh and temperature had an effect on power.

<{POST_SNAPBACK}>

So what's it making? 240rwkw?  250rwkw downhill with a breeze? 

I doubt grip was an issue running that power?? 13.0 on slicks. ??

This is why I'm not a drag racing fan per-sae. Anyone can have a kazillionty killowatts on 'X' dyno, but it will never perform as it 'should' in other peoples eyes. Everyones best efforts are too easily dismissed, and unless we were there and driving, we can't see what the conditions were like..

Geea mentions 300rwkw will be good for 120mph, where does that put F6's like yours running 120mph with 370rwkw? and mine (to an extent) running 12.80 @ 115mph? It's easy to dismiss..

I doubt they run there cars at 40 deg track temp + 62% humidity over there, as Lucus and Greg did..

I'm not  ( much ) but just puttting a few things into perspective, for the eastern staters...

Guys I've never run slicks or front runners. I use MT Street radials. Rob and Dave are the same. I think Rob actually used Nitto's which are not as good as the MT ET's. Also my best of 10.6 was done at Heathcote during the day and it was 26C.

These are all excuses. It also doesn't matter how many Km's a car has either. 300rwkw's is still 300rwkw's. After some more Km's it may free up and generate more but that is the figure that was quoted. 300rwkw's should be doing around 120mph in an auto. 111mph is around 250-260rwkw's. You can choose to believe me or not it's upto you. What reason would I have to lie.

MT Streets or Nitto's are far superior to OEM tyres however.

Does your car have a hi-stall converter or does it run the stock unit? A hi-stall will provide a lot more torque multiplication than a stock unit, aiding the car getting off the line.

As you said, I'm sure most auto T's would run a low 11/hi 10, but we are in unchartered waters with the new 6-speed auto.

I'm sure these times will improve no doubt

You're spot on. A lot of factors can cause slower times on the 1/4. Traction due to different tyres, driver experience, track preparation, stall convertor and many others. These will all affect the cars ET. What they wont impact on is the cars MPH. I've actually found that on runs where the launch isn't quite right I can end up with higher MPH. The MPH is what I have been referring to. 111-112mph is nowhere near 300rwkw's. One of the guys has stated that the temp was 26C which won't have a big impact either.

I'm not having ago at anyone, hell I don't even know those involved. I'm just making an observation based on my experiences. 111-112mph would equate to around 250-260rwkw's. 300rwkw's should be running around the 120mph mark. These numbers are based on what the guys have been running over the last 2 years. What you do with this information is entirely up to you. You can even choose not to believe it. Doesn't affect me either way.

I have to agree with Craig on this one.

My ute has run a best of 12.89 @ 110.27MPH in full street trim, hard cover, tail gate, spare wheel, standard stall, standard suspension and standard Dunlop 17's with 260rwkw's.

[Buf-Phoon]

Have to agree with the above, my T ran a 12.701@114.8mph with APS phase 2 complete with Unijip making 280rwkw:blush: running stock dunlops.

Ambient was 28 degrees with 70ish% humidity so you would expect with an edit tune for the time to be around 1/2 second quicker.

[Romulus]

Well then we are all in agree-ance that the BF F6 ute is making 297rwkw minus ~ 20-25rwkw power loss from ACT correction = 270rwkw. That would make sense considering the et and the mph the car ran.

I'm sure the drag tune that Greg will get from me have will take into account these niggling correction factors that rarely rear their head on the street, but do at the strip.

[G6ET8U]

I have read the above with interest... and have a few questions...

300rwkw's equates to about 120mph... does that only apply to the T? If I was to have a similar power level in a car that weighs about the same as T would I end up with the same mph? Just curious...

And just as a side note, I find it interesting that all T's with X power level are able to achieve Y mph... I suppose it makes sense though when you think about it...

My only trip to the drags I broke a drive shaft (kind of put me off breaking my car again)... so no mph for me

well done greg.

Ben there is now way lucas has anywhere near 300 now since he removed all the pipe work ect, that's obvious in his time and mph, My xr ran 114 mph with 270 rwkw's ive already told lucas he will need a retune since removing the pipe work.

<{POST_SNAPBACK}>

So how much power do you think the ute lost? Unlikely a great amount from pipe changes only.

And further to our conversation yesterday, I spoke to Greg, he has no boost issues, and his car is running in closed-loop boost mode. I'm kinda curious what would make you think it wasn't when in fact it is.

Did he tell you who's tune he liked the best?

[Romulus]

300rwkw / 120mph in an auto probably, not in a 6-speed manual. More likely 340-360rwkw in a 6-speed manual. I can't speak for the 5-speed manual though.

[Xtreme F6]

So what's it making? 240rwkw?  250rwkw downhill with a breeze? 

I would guess 260 ish

I doubt grip was an issue running that power?? 13.0 on slicks. ??

Grip wasnt an issue with the street tyres and the ect streets where an overall bigger diameter which hurt it.

Geea mentions 300rwkw will be good for 120mph, where does that put F6's like yours running 120mph with 370rwkw?

Mines a Manual that's a pretty obvious one, Dont compare autos with manuals, its not anything comparible. Also im quite gentle on my gear shifts ect and that will always let me down.. Oh and dont forget I have to use 5th gear.

[Xtreme F6]

I think you may have misunderstood the comment that Simon made regarding grip. He wasnt talking about my ute he was talking about Gregs. im sure gregs et would have faster if he had been able to stall higher and use the extra grip to improve his 60ft time

im not sure exactly how much rwkw Gregs is running (he did tell me but I forgot) but he went 1 mph faster than me and .28 seconds quicker than me with out stalling so id say its a pretty fair comparission between the two cars.

I ran the slick because they we're there. as I said above I have the capacity to stall to 3500 rpm on the convertor but havent had time to see simon for the changes to the tune so I was leaving the line at around 2000rpm anyway.

do you really think my utes only making 240/250 rwkw when it went 1 mph slower than Gregs did?

Your right, I misread the grip comment.

And Simon mentioned you have no-where near 300 rwkw 'now'.

Greg made 298rwkw on APC's dyno, you have a similar mph... this is why I said drag racing aint my thing.

Then Simon says his XR went 114 mph on 270 rwkw, based on that logic, you would have been making 240/250 ON THE NIGHT. any other cool night, it will obvously make more. But utes weigh more, his was on a cooler night etc etc etc etc...

Nothing adds up. This is my point, not digging but different night, different cars, it's all out the window.

Now, stick with me on this.....

I could compare your 12.89 @ 111 to my 12.89 @ 112 ( The best I ran on Simons' tune )

That tune made 299.7rwkw on Actives Dyno, After that run, and a fine tune from Simon It went 285rwkw on APCs' dyno, so I guess a genuine 275rwkw in a manual with that tune. You following??

That would equate to roughly 260rwkw in an auto, at my guess.. Pretty line ball with your car in it's current state..

Now this starts to make sense, and the planets start to align.....

Also, Greg would not have been making 300 rwkw last night either. It was hot and humid, he would have been down on power aswell.. Mars now lines up with Jupiter, and there's an eclipse forming..

Get your tune fixed, bring her up to the dyno day with me and pappy, we'll have a wizz on the road and see how they compare in real life. I doubt there will be bugger all in it between all of them, rolling start or mid gear accel.

ben the last time u ran my tune I was at the track with you and the car ran a 12.85 @114 but I guess if you want to quote it as less that's upto you

just to get off track for a second.

that was a great article in the latest perth street car mag. well done simon.
