Tonner @ WSID

[BLK 1T]

Just thought I would throw this out for anyone to comment or ignore.
Unexpectedly ran the tonner at WSID on Friday nite with the following numbers. Had four runs - could have had 10 there was no-one there and talking to the WSID guy in the staging lanes Fridays havent been popular and may not continue post Xmas. My though is its the worng time of year, too hot for the turbos and too close to Xmas to be spending $$$.

60ft 2.341 / 2.303
ET 14.609 / 14.611
mph 95.86 / 95.12

Now the real numbers - 217rwkw and 1975kg (on WSID scales), road tyres @ full pressure etc.

I ran similar times on a Wed around 6months ago.
I wasnt disappointed given the circumstances.
Over to you guys.

Forgot the car profile for those who wouldnt know it. VY11 LS1 M6 tonner only mods Tri Ys to single 3", 2 hole mod + GTS pipe and Sonny tune.

I have no idea about all this stuff Phil, except to say ... as long as you had fun and are happy with the car, nothing else matters.

1975kg hey ... that's even heavier than the Coupe was. It ran 13.5 with a 383ci stroker so I reckon that says something about what that sort of weight will do.

Ran into a well known tuner (the one without a workshop) at the track on Fri. His theory is, every 100lbs less = 1 tenth sec or thereabouts. So losing the 8ft steel tray would gain around 0.8 sec I think - not going to happen any time soon.

Gday mate, jeez those things are bloody heavy...did you take the tools out of the back of it? :stick:

I saw a crewman out there a few weeks ago with a mafless tune in it running 14.0 from memory on street tyres... he'd had plenty of practice and was running his street tyres at 20 psi...i dont know how they compare to the tonners in weight though.

The key to bringing the times down towards 13's in the tonner is in the 60''times, letting down your street tyres will help but mainly its all practice :driving:

As a general rule every tenth saved in the 60' time will shave 1.5-2 tenths off your et.

Good luck.

"Gday mate, jeez those things are bloody heavy...did you take the tools out of the back of it?"

I know you are kidding. Street weight is around 2150kg.

"I saw a crewman out there a few weeks ago with a mafless tune in it running 14.0 from memory on street tyres... he'd had plenty of practice and was running his street tyres at 20 psi...i dont know how they compare to the tonners in weight though."

I would have thought if I wasnt getting wheelspin out of the hole tyre pressure wouldnt be much of an issue.

"The key to bringing the times down towards 13's in the tonner is in the 60''times, letting down your street tyres will help but mainly its all practice"

I think having 4 times over two meetings that are almost identical 60'/ET/MPH means Im on the limit of the car or the knucklehead behind the wheel ATM.

"As a general rule every tenth saved in the 60' time will shave 1.5-2 tenths off your et."
Would have thought a tenth in 60' might have been more than that.

Hey man, not bad at all with all the weight.

I reckon, drop a few PSI in the tyres, loose the tray and spare and youll will go very close to 13's.


Look forward to hearing the tonners progress.

Maybe Phil, but 4 runs is hardly what id call a wealth of experience, there's maybe more there if youre keen to keep trying. :)
You may see gains experimenting with stall speeds, launch, tyre pressures etc imho.

Dropping the tyre pressure will allow you to get more revs happening off the line which WILL result in better 60's if you can get the balance between spin and grip right.

Best to speak our resident m6 1/4 gurus such as Lautray & Utesta on this, they'll point you in the right direction.

Absolutely right mate - I am no expert and I omitted the numbers for the runs where I muffed the start or a gear change. Still its a bit of fun but I think the tonners drag days will be limited until I can find some KWs or lose some weight.

Its also alot of fun to get out there, try a few new things, and discover what works for you.

I have a VU SS M6 and was doing 14.5's with a 225rwkw maf tune, mainly because of my inexperience, and the lack of a good clutch.

With a Textralia (clutch) and rip shift, i got it down to 14@103. Ive never bettered 2.1 to the 60. Even with ET Drag Radials. I still enjoy it the times i do go down, and i know theres more in it, if i get someone more experienced to pedal it.

Its a great feeling to get the goal yourself though :D

now im happy the barge ran 13.71 with full tank baby seat spare and me in it @101 mph you want me to punt your two seater down the track :stick:

time for sonny to do a mafless tune and lose the extra weight and sum fuel and may be i will see 13.2 or 3 very quick for a barge that i think would weigh 1750kg or more as i raced it.:)

[wagnman]

Geez I am amazed how heavy the tonner is! I always thought that they would be light like the old HQ/HZ tonners.
I think your doing well with it though mate.:thumbs:
At least your having a go and having some fun doing it!
Why butcher your work ute and spend heaps of time trying to reduce weight before each meeting when its only mildly modified and any time you get in a highly lightned form (ie with so many bits removed youd never drive it day to day like that) will have absolutley no bearing on how fast the tonner really is on a day to day basis.
Thats the problem I have with alot of the ricer guys that claim that their car has x rwkw or y ET but when you look at how their car was tuned to get those rwkw or ET figures and then look at how their cars are tuned when they actually drive them on the street there is no comparison and in reality they dont have any where near the rwkw or speed that they claim they do.:toetap:
I think your on the right track with the tonner mate. If its a street car I think it should be dragged "as is" without doing things to it that you wouldnt do to go out for a drive with your mates on a Saturday night (ie clean out all the work tools/ rubbish etc) at least then if your time slip says that you are driving a 14 second car you know that your still driving a 14 second car on the street! I would laugh like hell at someone that spent all night the night before a meeting removing stuff just to drop a half a second at the drag strip to run a 13.8 or something only to be left behind on t he street by the car that ran a "un-lightned" 14 second pass.:whip: :nana:

Wagnman
You are right it should be a light car except my guess is the 8ft steel tray and 7ft trundle add up to around 350kgs. Be buggered if I would pull the tray off just to get a time.
Rest of your post is spot on.
Richard - you need a lighter driver.
Thanks Dan makes me feel better about the time.
I reckon the answer for me is 4.11 gears to start with and see what gains that makes.

Thats my view too wagnman. Well put.

First time Ive posted a photo so lets see if it works.

Thanks Tiger
I saw it didnt work as planned but I didnt have time to play around with it yesterday.
Richard - its called "run what you brung" dirt and all.
