Sam's VN

dyno'd at WAPerf today at 326rwhp, happy with that for a stock motor

Mitch didn't even worry about tuning it, he said he'd be happy to do it but honestly the AFRs and WOT map were close enough to make no difference.. so we dropped the fuel pressure from 65 down to 58 to make the AFRs prettier and left it at that. said I should just wait til the cam / heads are done and do it all then.

He did however adjust my speedo properly so it reads correctly now (was low by 12% ... 3.45/3.08). Although, the car did try to eat a PCM by cutting power to it half way through a burn... think the immobiliser must be to blame there, has a time out on it.


picked up a bottle of genuine Holden coolant for it on Mitch's recommendation..





got the thermo fans wired up properly last night.. one relay per fan, 6mm power to relays through 50A circuit breaker. Took me til midnight but they run perfectly now kept her cool in traffic and more importantly on the dyno.



Filled the hole in the floor this morning, so much nicer to drive now.. amazing I'd forgotten what it was like !

Installed centre console this morning also, that's a pretty major win for the interior although I still don't have a manual shifter surround..

Today I want to try to wire in the stereo, and work on getting the dashboard back together as completely as possible.

Still going strong - this car's in Townsville with me now.

To date have only managed a 13.763 at the track up here.. the locals reckon it's a slow track but I reckon I'm just a vagina/spastic/noob on the clutch. All runs end up at 104-106mph, not really a die hard 1/4mile fan so I don't know if that means I should be going quicker or I'm going alright.. 60' times are in the 2.5second area.. which I'd imagine is quite rubbish. Hopefully I can improve this in the near future

Meanwhile, bit of work on the other VN, she goes alright for a donkey 5 litre.. and a few odd jobs on this one like sourcing a decent local diff builder for 3.9s and a truetrac to piss this locker off and make it a bit nicer to drive around town, as well as give me a hope of getting it engineered. Got VY maloo brakes I'm preparing for paint and they should be good to go within a week or two.

Really I'm waiting on stable internet access at my place up here to start sniffing out which local workshops are decent and which to steer clear of, and hopefully find some sort of modified car scene which to be honest I haven't really seen much of around here

[savage1987]

had 8 runs on Saturday night with a new best mph of 107.91, and the quickest run so far at 13.26something.

Almost happy with that, but I want a 12 before cam.

Underdrive is on the car as of yesterday, I don't really expect that much difference from that alone though

cool convesion mate. would go a bit better than the old v6!

i had trouble with my cae headers on my big block, they didnt come close to fitting!

hav you thought of getting rid of the pod? that will be suckin hot air and slowing things up i bit!

Yeah mate I need to do some serious research into leaning the radiator back and fitting some sort of OTR, not really keen on running an airbox if I can get away with it..

and yes, certainly worlds apart from the old boat anchor

[savage1987]

Looking for suggestions on a cam.. decided to go a little bigger on it, to complement a nice set of heads.

No longer after the 222/228 113 .567/.567 I was looking at before. I still want to stick with a Voodoo grind for my own weird curiosity mainly, so here's the options:


durations at 50thou'
227/233 113 .584"/.584"

232/238 113 .599"/.601"

237/243 113 .600"/.600"


Just interested to see what people's opinions are on these grinds based purely on the numbers; more info on the range here: http://www.lunatipower.com/ProductGr...?id=288&cid=60


Before making the final choice I need to do a whole lot more research including having a good talk with Mr Higgins who I'll use for the heads - he's bound to know what will work well with his setups better than most





Also need to do a bunch of research on how a shot of happy gas will effect cam choice and generally grow to understand how it changes the overall airflow in the motor.

On that topic, if anyone has any info / tips to share on nitrous setups that work well on LS1s, I am trying to sponge up as much info as I can in that area before making a decision either way.

Getting pretty close to the start of what really will end up being a whole new combination that I've personally never played around with before - I've never even dabbled with a basic cam swap before so I'm really just jumping in the deep end with this one. I don't want to do a half assed job and end up wanting more. This must perform

[ADAM 26]

have a look at some cams on a 110 lsa, will wake up the torque that the ls1 really lacks.

personally, i would not bother with a cam with less than 230/230 duration for a non-daily.

if you want it to really move with a big cam, you will want some 3.9 or 4:11 gears. that will make a HUGE improvement, even with a stock motor.

[boggers007]

The last cam 237/243 is very similar to gm motorsports turbo killer at 237/242 and that nets some serious power and quarter mile times so id say the lunati on should just do as good as that.

[stockergts]

sounds like what i said when i started getting all my parts that grew into something much bigger now running just over .650 lift

[savage1987]

Thing is I want this to still be useable as a daily if/when the need arises.. hence the 113, I'm thinking they will probably throw less fuel out the ass end than a 110 in an urban environment.. bit better on highways too. Or am I way off?

I suppose really even if I get it wrong it's not that big a deal, swapping sticks isn't that hard in these engines after all

And I guess fuel use will come down largely to how I drive it.

Got 3.9s in the shed that need to be installed when I get around to it.

[ADAM 26]

iv got a 109 lsa and drive it everyday, but its low lift and short duration.

the low lsa makes it pull like a freight train. and i get about 450-500km from a tank

Nice. Definitely food for thought

hi mate

currently doing the conversion in my vn nearly got the thing running. What did u do about emissions in regard to a charcoal canister as such? Do u need one for a emissions test and did u run a vacuum hose for ur fuel pressure regulator?

any advice would be great

cheers

[hRTHSV]

Sam, after driving my VS with an Ls2, I would make sure you don't have to much grunt down low or you'll just turn the tyres into smoke. I have revised my cam selection for that very reason, no point having to much bottom end if you can't use it.

I haven't got a canister in mine at the moment, I'm unclear how to go about setting that up. I just blocked off the vac hose on the motor that usually goes there.

There is no vac hose run to my FPR, it's set at 58psi and stays there.

You revised your choice to a bigger cam then? Interesting thought.
