RUNAMUCK

Narrow band just has way way lower resolution. The nrarrow band sensors have one wire, the wideband ones have 5. (Although one mite be for the heater wire to burn any crap off the sensor)

Those kits with the LEDs are just a narrowband thing.

I dunno about Viva's, but my datsun 1200 had the tank vent run out of the top of the filler neck, and then down through the boot floor, through a chassis rail and after a wee dogleg out to atmosphere.

You're choice of cam will dictate your dynamic compression ratio. This will have the biggest influence on how much static compression you can run.

I was fucking mint when Aaron had it. And it looks like it's been loked after well since he sold it too.

Lest we forget that trick!

Probably need to be registered to veiw the pics, http://www.nzdatsun.com/forums/viewtopi ... 8&start=30

You have seen the pics of it aye? It's a pretty sad sight!

I'll pass that on to the peeps at the club when I see them next.

If any of you fullas want to have a go at drag racing, but your car aint road legal, PM me and I'll give you the contact number of the local tech inspector. For a fee of about $50 (I think) you get a tech inspection, (which is like a basic wof check, without worrying about all the gay shit like loud exhaust, and other HiPo modifications that WOF men get all out of shape about) then you can send away and get a log book which lets you race without WOF of rego for 12 months. If you don't get a log book in time you have to get one on the day which costs a little bit more.

Tech inspection is fantastic if you don't drive your car often enough to keep it road legal all your round. Or if you don't have cert for a +T, or +S/C etc.

I can't say either way, but I do know that you'll be able to tweak your LSA being as to how your motor is twin cam. This will denote your overlap, which is the critical thing I supose. As may have been said above, (or not) a supercharged motor can stand much more overlap than a turbo engine. Although I think with an angry turbo (and definately with a nitrous) cam, the LSA is a bit wider, and the exhuast event begins a bit sooner. (before BDC) This (with nitrous anyway) helps to utilise some of the thermal expansion to aid the evacuation of the spent charge. (since it's being added artificially on the intake side) This does cost some power, (The wider the LSA, the more power it costs) but where the power is being added it's a trade-off. I would assume that an earlier (BBDC) exhuast event would also bode well for a turbo engine, as it's going to help get the turbo spooling faster. Since more of the spent gasses are still expanding. Also on single cam engines, wider LSA's are ussually accompanied by smaller overlap durations/lift, so you don't have exhuast gas back feeding out the intake corrupting the vaccuum signal, and impeading the compressor wheel while the other gasses are trying to spool the other side of the turbo.

I suppose ssuperchargers are more flexible in what cams they can run with. (Think about the millercycle engines) I did once run a can with 106* lsa on my datto with ther blower. It went like fuck too. (For a wee while)

Dunno if what ive written is relevant/makes sence. (It's probably a load of horseshit anyway)

Also with a positive displacement blowers, any unburnt fuel that gets blown out the exhaust valve from overlap can actually help to cool the zhorst valves.

Skids! http://www.facebook.com/pages/Pegasus-B ... 2392950137

Here are some skids from the drags on friday night.

http://www.facebook.com/pages/Pegasus-B ... 2392950137

My skid (White datsun 1200) probably wasn't the best on the night, but who'sever skid gets the most likes wins. So be a GC and give my skid some likes.

Chur.

Maybe the flat peakers wont be able to afford gas to go that far? lol

My skid (White datsun) went untill my temp gauge went past 120*C I had hoped my tyres would pop, but I ran out of cooling before then.

THANKS for the pics mate!

The only downside of racing is you seldom get to see any of the racing, and especially never get to see any of your own runs.

That supercharged '69 Dodge charger is pure sex! They've gotta be the best looking muscle car that the US ever built. (Big call I know, but thats my feelings anyway)

Nah. thats another mate of mine.

When you say your leaves have been flattened out, did they remove all the elipse from them? In my experience leaves that have no curve in them have real trouble putting power on the ground. They need the shape to "hold" the tyre on the ground. And with the power you'll have on tap, you're going to need all the traction you can get. If I ever get my leaves reset, I'd get the eyes reveresed for certain.

I didn't break any records tonight. Didn't break my car either! YAY!

Wasn't many takers for the burnouts. One skidline, one skidvia, and two datto 1200's!

I just sat in one place nudging the redline untill my temp guage went past 120C. Should be some vids up soon. (most unimaginative skid ever)

I ued to know a dodgey cat who sold a complete shitheap Avenger sation wagon dereged, with dereged toyota plates on it. The buyer knew all the the above, and got it for $60.

The next day it died. They wanted their money back. WTF?!

I think the diaphram is dismantled, and then reassembled with the spring on the other side of the diaphram. So it runs Advanced under normal conditions, (May need to adjust base timing to suit) and then as the boost rises the pressure make the arm retard the timing. (I imagine the weight of the spring used would need to be a bit clever)

It's wholley possible the factory rotoray ones had two diaprams back to back, so that it could both advance from vacuum, as well as retard from boost. (Although, don't quote me on that one)

Another clever (But very costly) option would be to use something like an MSD 6AL BR module. These retard your timing electrictronically as the boost climbs.

Caveat emptor motherfucker!

I have no experience with chineese turbos, but I did see cockram nissan were selling them a while ago. (I assume they still are) So it must say something for them if a big dealer like tham will sell them, and stand behind them too. (Although they were unable to tell me if they were carbon sealed or not)

Aside from that, I did read an article in some uassie car mag about cheap turbos. It reckoned ones with a 360* thrust what-cha-ma-call-it were worth giving a punt.

If you have the documentation saying AIWI, then he can GTFO.

Tell him if he's that ned out of shape about it, you'll see him at the disputes tribunal. (Make him take you there, and he can pay the cost too, after all, it's his problem)

They'll see what you've got in writing, (And get your witness to attend too) and tell him to go eat a dick)

If people were keen to go back up to the go-kart track, it would be insanity not to head inland just past cheviot, and cut through Waiou. The road spits you out after the hundalees (sp?) about 200m away from the track. Plus the road has sweet fuck all traffic, and is a great mix of straights, hills, and twisty-turnys. I passengered that route last year, and spent the whole time wishing I was driving myself.
