Vid to Analyse please.

Ok, you all know me, and you all probably know my cars.
My mods for this one, are as below.
The power is now around 154kw and 410nm of torque from 3000-3500rpm.
I had a few runs at Willowbank last night, With the best being a 14.6 @ just a bees donger short of 96mph.
Time is ok, Im happy with it, and extremely pleased with the MPH.
My problem is with my 60ft times.
At the moment, I run slicks. I dont get wheelspin, I have whats meant to be a 3000rpm stall, and the 3.9 diff gears, but still the best 60ft I managed was a 2.17. I used to get that out of my stock drivelined Fairmont single spinner.
SO heres my problem. What am I doing wrong. Whats the car doing wrong? My stall wont get anywhere near 3000 (2500 max). With this combo I should be seeing 2.0's to 1.9's.
I have a vid here for people to see from inside the car.
Please tell me what you think.
I think its just falling short on stall speed, I am seriously contemplating a 4000 plus RPM stall converter, as I dont do much stop start driving and the 3000 converter is a real breeze to drive with anyway.
Also, ignore at the end of the vid, Im still having a fuel issue, which will be sorted this week, Im just making a short vid with it to send to my tuner.

Hi there mate,i would be trying to bring the revs back a bit on the changes ie try 5000 see how that goes just keep playing around or just change when the torque starts to flatten out.It will take a fare few runs to get it spot on.I would try a set of 4.11 gears.Its all trial and era. Sound good to.cheers

The slicks I ran as they are a fair whack smaller than my rims and tyres bring the corrected diff ratio to 4.18's iirc.
I tried shifting early on one run and MPH dropped to 92.33, with a 14.892 at the end.
Thanks heaps for the advice though. Heres another vid of practically the same thing:

And a little clip of the burnout, lol. It DOES sound like a 202 like I was told:

na mate go a 4500 stalie not practical for road use but good for track as for slicks there prog bogging you down to much increase the presure by a few bar.

or go a semi slick.

4:11's are good but it will reduce your overall speed although thier great for quick take off.

hope this helps mate.

The thing is with a big stallie, I drive to the corner, and there is a highway, I drive the highway 40km till I turn off, and one set of lights later, Im at work. In the arvos, its reverse. I dont drive around town, Im not in stop start traffic, and with the converter thats in it at the moment, its an absolute pleasure, so Id love to go bigger.

au11futura · 03-09-2009, 08:50 PM

well with the 4500 stalie mabey you'll get to the 3000 you need.

51OAU · 03-09-2009, 11:01 PM

supercharge it now, u gonna do it anyways, so why bother getting the NA right?

The Monty · 04-09-2009, 04:48 AM

Any gain I make with it N/A should help it once its s/c anyway, so seeing as Im slowly getting closer to that record, I may as well keep going N/A for now.

broken_suave · 04-09-2009, 02:03 PM

I know its probably got nothing to do with it, since you had the solenoid turned up and you're manually shifting anyway, but would turning 'Econ' off have any effect? I know that when I'm giving it some on the street, manually shifting with Econ turned off feels tighter than manually shifting with it on. I dunno if you've tried it or not.

Stattic · 04-09-2009, 02:15 PM

i was wondering about econ myself lol

The Monty · 04-09-2009, 03:51 PM

Yup, my last run was done in ECON by accident, resulted in a 14.70, @ 95.xx mph, so no difference if manually changing above redline.

josh i'd reckon go a 3500 rpm stally.when i used to run mine i'd dump the clutch around 3500/3600 anything more and it would spin.i don't know how much stress a 4000 rpm launch would put on the drive train mate with the slicks hooking up.a 4000rpm stally would be better but i don't know if it would handle it.
you've got the power and the traction ,you just need the rpm to get it all moving off the line.

what stally dose stav run?he should know something about what works best
i remeber casper use to run 3000rpm stally and cracked some good numbers with his vct.

The Monty · 05-09-2009, 10:25 PM

Stav runs the same stall as me, but seems to be able to get it to stall higher.
Im getting the tailshaft done as well before the stall, or at the same time, probably a nice two peice jobbie.
Dont know if the diff will like it too much though, lol.
