Hi all,

 

I have been scanning through the forums trying to find drag setup info for Our LH/LX 4 door Torana that are tried and true.

 

Are there any guys or gals out there that are running quick times without running ridiculous converters and rear gear NA? I understand quick/fast is a matter of perspective but more interested in the setup side of things.

 

My setup is below just interested in hearing some opinions as I won't have the massive stall. 

 

Modded Ls3 with around 450rwhp

 

Built t700 trans, more stall converter, 3.5" tailshaft

 

9" with true track and 3.7 ratio

 

90/10 front shocks, standard rear springs and shocks

 

MT ET street radials 26x8.5 

 

Still haven't weighed it since doing the conversion though. 

 

My full weight WB stato is a boosted Ls running bottom 10s so the turbo does the work and I still have tall gears and modest converter. I haven't done much driving in the matchbox car Torana yet. 

 

Thanks in advance.

Have run several combos down the strip. Here they are:

 

LX torana (1355kgs) 355 with 340RWHP, T700, 3500 converter and 3:9 gears and ran 11.9 @ 115MPH. Stock suspension

LH Torana (1360kgs) 355 with 385RWHP, T350, 5500 converter and 4:11 gears and ran 10.99 @ 123MPH. Chassis kit and standard Torana set up suspension

LH Torana (1360kgs) 355 with 330RWHP, T350, 4000 converter and 3.5 gears and ran 11.5 @116MPH. Chassis kit and standard Torana set up suspension

 

I find that getting the gearing all sorted with the right cam and stall combo is very important.

 

You should be running easy 10's with the HP you have but it all depends on gearing and converter suiting your cam choice.

 

My two bobs worth.

Work with what you have and make it launch hard and get up on those rear tyres.

Talk to Mumbo about a big rear sway bar...30mm.. to keep the launch square to maximise the tyres

60 ft times and the first 1/3rd of the track is the important bit.

Might need some suspension sorting

Thanks!  They are exactly the type of responses I was hoping for. I am still early days on driving this thing so haven't really put it through its paces yet. 

 

I do understand matching the converter to the cam etc so I will see how I go with that. Your combo Gerry shows the effects of the gearing and converters really well. Was the chassis Kit added to try launch the car straighter? 

 

How does The LH torana leave the line without any chassis/suspension mods?  

 

Seems my setup is a good enough starting point then so I will see how the car behaves in the 60ft and work on the short times before going full on. That should help me decide on converter and gearing at least.

 

The car has a 24mm rear sway bar that bolts between the 2 lower trailing arms and curls around the diff centre. Not sure if they are any good?

The chassis kit in the LH is the best thing for getting out of the hole I reckon. It kept the car straight and stopped the front wheels from lifting in the air. My 60ft times ranged from 1.5s to 1.7s and all runs were with 26" ET radials.  Those 3 set up were most consistent with what you are looking at.  I have run manuals too but not good compared to the autos.

 

By the way, I ran 18psi in the ET tyres.

 

It is a blast and only practice will get you good times.  The best you can do for now is get a stall made up to suit your cam specs and diff gears and things will progress from there.

 

Have fun mate.  I will be taking my new beasty up for a blast soon too. 500hp manual so will be fun...

Yeah practice makes perfect. This is supposed to be a street car cruiser though so not sure how far my mods will take me. Hoping not to go flaring converter and high cruising revs if I can help it.

 

500hp manual should be a handful and a lot of fun. 

 
I will run it as it is now, see how it behaves and go from there. I ran 18psi in the ET tyres also with my WB.

 

Thanks again.

Hi Jason,

 

I will also throw in a vote for having a chassis kit.

 

Whilst my LX doesn't make the same power or run as quick as Gerry above (and is nowhere near your power levels) - I've had nothing but super consistent, reliable times at the drag strip (used to race a lot, but bugger all these days)... my setup is ultra conservative and very basic (cheap and dirty!) - the only exception to that rule being the chassis kit.

 

So just for interests sake, here is another combo to compare - adding this because it always hooked up and 60 footed so well:

 

LX (1480kg - heavy bugger!), 383 with 310rwHP, T350, 3200 stall, 3.7 gears. Ran 11.7 @ 115MPH with 1.6 sec 60 foot.

 

Rear suspension notes:

Second hand VP Commodore springs ($30 from the local wreckers!), with Pedders Sports Ryder shocks. Standard old (UC style?) sway bar with link mounts. Boxed trailing arms, rubber bushes everywhere. And as mentioned earlier, chassis kit (mine's a CRS one).
