VE SSV A6 in the 10s again.

After running 10.82 with my NA 7lt last year I refitted the factory 6lt, mods are.. 216@050 cam, extractors and OTR, A6 and engine tuned by Joel Prince... 11.8s consistently NA. Fitted some N2o... after dabbling in the 11.1s @ 122 for a while, last Friday night the old faithful with 134k on the clock went 10.95 @ 124.48... changed my wheels and drove the 2 hour trip home. The A6 is still going good with lots of street kms and about 50 passes down the 1/4 mile with both very different engine combos.

Good work mate.
Gotta love the old :nos:
Hey but even without the:nos: 11.8 is a great result with only a mild cam, any more details?

curious about the cam, are you talking about the Camtech 216/226 or was this a custom grind?

Yes custom Camtech, same intake lobe but different exhaust, its 224 and lobe separation is 112.

Pipes are 1 7/8 Pacemakers 4 into 1, with 3" Hurricane exhaust, VCM OTR and tuned mafless. 3.7 diff ratio with Harrop Trutrac and a 3000 TCE converter.

I heard it needs roo in the tank and lean on it some more ;)

Yes it was pretty rich and not much timing in it, basically enough to get a ten, Next year we will run some roo 16 in it and lean it out and run some more timing it has over 130 mph in it and the car always ets very well has stock springs and suspension still. The air is pretty crappy aswell atm here. We havent dropped the exhaust or nothing yet either. It will go faster with time. We are just happy the A6 is still going strong. Leaving in 2nd had 11 psi in the slicks (on 15 inch weld wheels) it turned the tyres for about 100 feet still and 60 footers slowed down. Keen to push it next year but so many cars now prepping to race I am a bit sidetracked with other projects.

Rockhampton now has E85 on the bowser.. And I have a VZ 6 litre (L98) stock bottom end with flycut pistons and rod bolts. 12:1 compression with 14 psi on top from a s400. and 1000 cc injectors 1500 HP magnafuel pump. I am confident it will go 140 mph plus in the 9s on stock internals. I have a power figure I am capping at it mind , but average power is what i am after and fast 60 footers with no need of 2 steps or transbrakes. As far as the compression Lionel Durrie is running 45 psi on 12:1 on small blocks on methanol, ethanol itself will handle the compression boost like alcohol but unlike methanol it needs it to work. Methanol will gain on low compression engines so I am taking advantage of this and upping the comp so it will have no lag and ET well to its mph. I have another few VE's cam only making good power with the A6 and good convertors.. The guys aren't really drag racers thats the problem lol. And if they do want to go for the occasional skid I will put the time into making sure there right before they go as always just to get the best potential.

As far as camshafts.. The L98 will respond to any camshaft, some work better then others, some make more power up top some down low. The most critical thing in these is spring setup. And I must admit , Garrys just has a set of 1518s he threw in and cam is dot to dot. He just slapped it together basically. The 216 intake works very well. Regardless of what rwhp numbers people come up with .. this cam is worth 50 hp at the track. I do think that if I had this car at willowbank or WSID in winter it would run 117.5-118 mph with very fine tuning to the conditions. If you want bigger go straight to mid 230s , 600 lift not a big split. I dont recommend huge splits in heavy cars, if it has a comp bump and adjustable rockers good spring setup , yes go a big split and turn it. But single pattern, big split whatever , is worth not much in heavy car below 7000 rpm. They are much more aggressive with less split , more intake duration and more compression. In fact I would say a 240/240 cam with 11.5:1 has more bottom end then garrys car with 216.. Going to a bigger cam with high comp is another 50 hp at the track but it must have the compression increase to get the average power up. You can do more things , valve job, very critical spring setup, 1 7/8 with proper merge collectors ( 2 3/8 - 3 inch) with twin 3.5 inch system, and it will pick up another few mph and be more aggressive everywhere. There is no secret to camming L98 heads. So much bullshit about I/E ratio on the web when people are looking at 28" numbers on a flow bench on the exhaust, but in the real world.. the exhaust exits at 400 psi, we do not flow at 400 psi on a bench. Ex is all about shape. If you run to much split on a L98 6 L cam only engine on petrol and u arent willing to turn it to 8000 rpm. Don't bother because it DOESN'T work..

Hymey tried to pm you your inbox is full

Put it into perspective for the southerners north Qld this time of year isn't the best for trying to be quick so this is a solid effort for these guys, gaz & Joel definitely have the A6 stuff covered (and tre-cool too ;) )

Hi there.I heard on the grapevine that this car may be for sale? I raced an old EH with triple webbers many, many years ago at Surfers Paradise .
My hubby says that a car like this would be good for me to get back into drag racing. He says that it would just be point and shoot. Just put it in drive ,stall it up and GO,he says.
He says that I would just have to sneak up on it a bit and not give it full throttle first time out ,or I would wet my pants.It would be a fair bit quicker than the old EH.But it ran flat 16 's
with av gas
I used to be able to flat shift that old EH 3 on the tree 40 odd years ago!
We were visiting the grandkids up in Gladstone and we went out to Beneraby Racetrack and saw your commodore run the high 11 second passes . Must have been without the N2O, my hubby reckons.
There was a young girl racing a Twin turbo Monaro and she was doing alright too! So us girls can still do it hey?
I have been searching some of these sites since I started to learn how to use these computers at our local TAFE that are running technology courses for us oldies.
My hubby says that your car would be a good one to buy because if our normal car broke down I could still drive the commodore to woollies for grocery shopping.
He also reckons that he wouldn't have to spend much time working on it, because he says that the tuning is all set and forget. not like the old EH. he was forever tuning the carbies and
replacing the gearboxes and diffs when I broke them!
Anyway I would like to know if your Commodore is for sale or not. My son in law works at Boyne on the gas and he told me that he heard it might be for sale.
So please could you send me a personal message, one way or the other
ps. You might think it a bit strange a woman of my age wanting to get back into drag racing after all these years but I have always been a bit of a tom boy and hung out with
the boys with hot cars ,back in the day.
I look forward to hearing from you.
Yours sincerely, Barb

how much nitrous did you throw into it?
i have similar setup 224/232 camtech a6 no converter though plus i have a dual stage nitrous plate setting the nitrous up but i was looking at spraying 150 - 200 would be great if i could get a 10 outta it also

How would this 216 cam run with 11.5:1 ? Noticeable difference over standard compression at the drag strip?

Good stuff I think NOS is headed for my car soon
