To be fair, it's mine and my Dad's. Just had a fantastic week at the Targa NZ! I'm gonna start putting up some info and pics about the car and it's specs.

Will be looking for feedback on how to make it more competitive, so let me know what you guys think. In the meantime, check this (http://www.flyingbricks.blogspot.com).

Awesome dude!! Sounds like a fun run. Any chance you've got any video's of any section of the drive?

Yeah, I've got a few tapes to go through. I'll try and pick out some good sections and post them up.

An embarrassing clip can be found here (http://www.tv3.co.nz/VideoBrowseAll/SportsVideo/tabid/317/articleID/37648/Default.aspx#video)!

I remember reading about your car (It is the picture in your avatar, right?) a few years back and falling in love with the PV444/544 series.

I wish I could do something like that @ the moment must be happy with some trackdays. All the rallys in here are on gravel. Something similar to Finnish Rallys

a little less understeer and brake lockup and you'd have made that corner just fine!

What can you do and still stay legal in your class?

Well, in Targa over here almost anything goes. They'll just bump you up a class according to the latest year that a modification can be attributed to. So you'll see a lot of of older cars with newer drivetrains.

That said, we like to keep things period and accordingly, we're in Historic, which is anything up to and including 1964.
So any mods which could have been done up to 1964 keep us in our class.

hmm. so like if (for example) bilsteins we'rent sold until 1965, you couldn't run them?

how does that work for pieces that are home made? welders have been around a long time, i'd think you could argue that someone in '64 could have made chassis braces and stuff for your car :rofl:

It's really down to the scrutineers' discretion. If original suspension mounting points are used you probably won't have a problem. We have had people in the past querying our 122 front discs - but that's legit as far as we're concerned.

In terms of bracing etc. I think you could go to town as far as that's concerned. Obviously there's a cage in there, so that's a pretty hefty brace already. I think once you start modifying the chassis significantly they'll probably bump you up.

There are provisions in the rules for composite panels where the originals can't be used due to scarcity. PVs are pretty scarce here so thats certianly something worth looking into. Especially with the pretty much "bolt-on" guards, hood and front panels. There are Healeys in our class with fibreglass bits for example. Carbon fibre PV bits anyone??

Well if you're going to go with fibre bits, why don't you widen the track while you're at it? That reminds me, you're not still running the original axle are you?

Other than that lose the SU's.. and consider seeing if you can get away with a 2000+cc in there.

i've been slowly working on fibre PV bits, taking forever though, silly compound curves and students time availability.

Well, I dunno about composite bits just yet, but it's in the back of my mind.

Axle has been changed to something much beefier with an LSD. It's great not having to worry about the weak tapered half-shafts any more, though it shows up limitations elsewhere!

Carbs are twin Weber DCOEs, 42s at the moment, but we may go to 45s or 48s at a later stage. We're getting away with a B20 at the moment, as it's essentially a big-bore B18.

what tires do you run? i'm simply suggesting things based on what i saw from that small clip of video. were you just overdriving?

igor
11-05-2007, 04:53 AM
Yeah, I went in too hot and took the wrong approach for that corner.

Dunlop tyres are mandatory for the event. We ran DZ03Gs for the first time this year, a (barely!) road legal Tarmac compound. Of course I'm only comparing it to a road tyre but the grip is astounding!

Size is 195/50R15 on our 15x5.5 Minilites.

Un-watermarked pics coming soon, then I'll post them here once I've figured out some hosting.

In the meantime see if this (http://www.groundsky.co.nz/index.php?Action=VEN&EventCode=0711&EntrantID=7556) works. Otherwise go to www.groundsky.co.nz and search Targa 2007 for car no. 54

So, what would make a tire "illegal?" Because it has too much traction or something. I have a feeling it's a realy obvious answer.... but yeah.

Nice car, I mean REALLY nice, looks like a lot of fun.

Thanks for the compliments!

Regarding the "legality" of tyres for road use, I don't know the numbers, but it's to do with the percentage of grooved area around the circumference of the tyre. In this case it would be the minimum allowable to maximise the "slick" area.

i think we need some stiffer springs in there, mate

Yep. It's on the wishlist. Just something we never got to in time before the event.

We weighed in at about 1230kg during the event. That includes driver and co-driver, safety equipment and full fluids.

I like it!!!!
I think you might wanna swap to a better cam if it dies already at 6100. Your idea of a rear bar seems to be a very urgent mod judging of the cornering technique.... 4.56 rear might be a good mod too...

How in the workd have i missed your thread?
Your Pv544 is looking great.
They are my fav volvo apart from late 60s 142.
I am hopeing to import one here in the future

igor
11-12-2008, 04:57 AM
Yeah, I'm lucky to have two - here in NZ there are only a handful. The rally car is currently the only one in the country registered for road use.

I know of about 6 or 7 here only.
Great looking cars.

122 front disks are homologated for the PV, as are twin front shocks. I have the papers somewhere if you don't have them to waive under a scrutineer's nose.

As far as updates, not a lot really. The car has been hibernating for a while - life has a habit of getting in the way of motorsport.

I'm left with mixed feelings after spectating at this year's Targa NZ (http://www.3news.co.nz/Targa-rally-closes-with-thrills-and-spills/tabid/317/articleID/127672/cat/70/Default.aspx). This is the event the car was built for and I feel it belongs there, but I sense a shift in the spirit of this event, with classic machinery becoming more scarce by the year.

The event's roots were more about running your old stuff hard and competing against similar cars. Now it's more about going as fast as possible as efficiently as possible. For the majority it makes more sense now to compete in an E30 BMW. And at the other end it's the big boys playing with GT3s and Nissan R35s. The ingeniously quick "home-built" specials are also dying back in favour of the factory-fast, computer controlled rocketships.

All of this adds up to a less colourful and exciting event as far as I'm concerned. And yes, we've contributed to this by not competing this year. Now the question is, do we buck the trend, fly the classic flag and go out and have fun regardless? Watch this space I guess.
