Who would win?? - Page 4

**Stav** · 21-02-2008, 12:06 AM

I dunno what came over the other half and then to flip back?? Whatever the reason I am glad.I am now .301 second away from a 13.9 second pass!!

technically .302, that'll secure you a 13.999

Stav is gonna throw down the gauntlet again!

**Stav** · 21-02-2008, 12:34 AM

Current record is 14.226 I was .0.075 away.My goal is a 13. It is closer than ever now but I am going to finish a few more mods off soon..

The Monty · 21-02-2008, 02:57 AM

Good work Stav, you are close, very, very close.

**Stav** · 21-02-2008, 07:11 AM

For a non workshop backed car I sometimes nearly gave up but somehow pulled out the next step to fix it and take it farther.The wagon has done 259000 kms already... I never stopped believing that a 13 is possible and it is with an au! One thing I did learn though...was that at those sppeds the 4:11 diff ratio pulls the car back..it slows the car down.Also the 4:11 make the back jump around on deceleration.I have considered a 2 piece tail shaft but they are much heavier than the single piece tailshaft. I may go to 3.9 or back to the 3.7 diff...but that remains to be seen.

ClassicAU · 21-02-2008, 08:19 AM

That is a fantastic result, and great news too Stav, well done mate!! Good to see your not done yet. It would be so awesome to have a wagon hold the record! I wish I could get anywhere near that, I cant even crack a 14! I must have one of those Friday afternoon lazy engines.

:
Best of luck mate, I do hope you get there.

You can get there.If your car hasnt got the kays mine has then its a good start. I think its the willingness to question each mod that each person says is great ..or the car feels faster!! one thing that sticks in my mind is that I am still running the Jim Mock race series headers. Someone once said they killed power at around 130rwkws .At 97 mph I estimate the wagon is pushing around 160 to 165 rwkws on that run.It last dynoed at 141 with af ratios of 10.5 to 1
My investigation had also shown that dynos af ratios were incorrect.My af ratios were more like 11.4 to 1. I have since tuned the car myself and have not or will not go on dynos unless its life threatenning.
I have also found that induction behind my headlamp collects the heat from my radiator and I see temps of 70 degrees celcius..

ClassicAU · 21-02-2008, 10:00 AM

So the air and fuel ratios make a big difference do they? I actually ran the car with a pretty severe exhaust leak, would that make any difference at all? It turns out that my extractors have warped and there is a visible gap between the number 6 cylinder port and the head. I didn't think it would make any difference other than the extremely annoying ticking noise it has developed!

**Stav** · 21-02-2008, 12:34 PM

Exhaust leaks destroy the tune.

I have no idea about the JMM headers, but if people say they kill power above 130rwkw's it doesen't mean that you wont be able to produce more power then this, just that above these powers more suitable headers would give more power and better times. But rather then listening to what people say, as alot of the time they say it wont work because they haven't tried, your best off looking at the spec sheets and working out what works best yourself. As far as induction temps go, I recently sold the setup I was working on last year, something of a similar design might be worth looking at.

I dont know what people say anymore..I listened and had to do almost everything 3 times over. In the end I bought alot of technical reading material and used that to go faster. Memories of what is said gives me a private chuckle when they havent tried these properly.
On the flipside its been really good to learn from everyone here.Most people have been very helpful and thanks heaps.

don't be to hard on yourself mate,its not as easy as it seems.
give us a run down on your times .
what were your 60 ty times?
what mph did you run?

The Monty · 21-02-2008, 04:24 PM

I know how you mean about K's Stav, Im just about at 240 000, lol. And last time I was out there it got spun over 6400 on all 6 odd runs ahahaha.

**Stav** · 21-02-2008, 05:38 PM

heheh ..its not only that..the darn cars fall to bits at these kays..it has been one thing after the other.Gearbox,engines,lsds ,alternators,starter motor etc. Even though the ba is a nice car I really like the au and want it to go 1 million kays.The heat,hard driving and built up traffic in Sydney kills the cars.Slow traffic sends auto temps soaring.At 70 kays my transmission temps are very low for example.

Its not embarrasing.You are a top bloke and were under the impression the car was pulling 144 rwkws . Cars break,tunes go haywire. I think that you shouldnt worry about it but maybe try to find the source of the power loss and get it fixed...My cars not fast because its fast.Its fast because I love my hobby and never gave up on making it better. I have tried alot of things on the wagon..most did not work and some did.Dont give up.At least you had the guts to front up and race the car. The journey starts with the first steps.

These are honest numbers for a newcomer and good on you for posting up the real numbers.

fact is you have basicly a stock XR6 Auto ute. Exhaust and CAI and flash tune don't change the fundamentals of the engine and you now know how useful dyno's are for comparisons.

I could and did always beat Stav on the Dyno but never on the track well once beacuse he did a way to lenghthy burnout but dyno is a tuning aid thats all and a flash tune will only get the best out of the engine you have.

Stav has worked this car patiently for years now trying lots of things. Best one I thought was the high stall converter. if you like drag racing make it your next mod but get a cooler for the trans too.

The Monty · 22-02-2008, 03:08 AM

D1XR2C,there was a guy AU2SEute, used to be on here, now known as Rapid AXE, he had a ute, around the same power, cam, exhaust, unichip, but that thing would never break out of the 16's, we never ended up working out why, maybe its something to do with the utes, as I remember it always seemed quick on the road, but something about it, was the 60's were really bad. Maybe the utes had big time tourque tags on the autos, killing there take offs, as I havent heard of a quick AU 6 ute, its kind of wierd.
I need to put mine on the dyno in prep for an assault on the strip this winter, make sure a/f ratios are all good, and try and get this ported head on, and a nice cam before I got out there. Its just hard with the stock driveline, no LSD, 3.08's and no stall, I think thats whats letting my car down big time.

You know my sentiments JonBays...all dynos suck imo.The stall converter at 300 dollars was a steal a 2500 rpm unit(my tach showed 3000). I have read about limp home mode on various converters pre edit and can honestly say my auto transmission has never been edited.Lat week I installed a transmission temperature gauge.At wsid this week I can state that my gearbox actually got cooler down the 1/4 mile than in normal driving!! 10/10 to the boys in Seven Hills Len Pendlebury of tci!!

Joseph ..get one of these.My car felt slow until this..However a diff gear change will help it feel tighter as well but its not necessary.

Kenny's ute was running LPG though.

The quickest AU I6 on here was Hambo's old AU ute ... so there's nothing wrong with utes at all. The only thing I'd think would be an issue with launcing with no weight in the back.

Nice work Stav ... Don't worry Joseph ... it's your first time out there.
I'd suck the big one the first time I'd race (I still haven't).

I think would would aid you though Joseph ... take the big rims off the rear ... you need stocker 16"s with grippy rubber ... and pressures dropped ... your 20"s have the thinnnest sidewall rubber ... there's no flex at all.

I guess it comes down to having another go ... and practicing more and more.

The stock auto's have such a low stall point in them ... to get a decent launch you will need a bigger stallie in there for sure.

Stav .... I'd think about changing your ratio ... I think the 4.11's are too short ... I think Evil Chief mentioned his 3.7 setup was great for the 1/4.

**Stav** · 22-02-2008, 05:59 PM

I have had a big think about it Simon. I am achieveing 97 mph at the end with 4.11's. At the moment with 2 of my 3 houses untennanted 3500 dollars in monthly interest is chewing up my funds fast. I think a tailshaft loop and colder weather is the best fix for this.

StealthAu · 22-02-2008, 06:08 PM

What revs in what gear are you hitting at the end of the track?

Does that mean that AU 15's steelies would be better then my 17 x 8's xr6 rims at the track or would I have enough flex. Sorry to highjack the thread but I'm about to buy a set of 15's and if they do better then my 17's that'd be another plus for them.

It would be a hard call, depends on wheight differance too, if the 15" wheel and tyre combo was the same wheight as the 17's then yes.

I dont know..I lost my datatlog info by accidentally pressing the erase button
:(
I used to pull 4700 revs with the 3.73's

3.73 - 4.11 =0.38
0.38/3.73= 10%
4700 =10% =5170.]

I estimate 5170 to 5500 rpm..

nothing embarassing about that mate,2.53 is a very slow 60ty though.
did you hold the brake and stall it up a bit ?
you should easily crack a 2.3 60ty with your set up .you should be good for a middish 15 sec run.
what mph did you run ?
what rims/ tyres you run?

poolkeeper · 22-02-2008, 08:38 PM

Yeah, most times I just floored it though as that felt faster
88mph
19" wheels, 245, 35 tyre
30 psi in rear
