When I was mucking around with cooling system issues one thing that helped was a better flowing pump. On their website it has a thing about the common train of thought that coolant flowing too fast means the radiator can't cool it down properly However slowing it down means it also spends more time in the hot bit, ie the engine https://flowkoolerwaterpumps.com/pages/why-flowkooler-hi-flow-pumps-end-overheating

Yeah that scan and print thing is clever, makes for a very tidy adapter

It's a huge pain for cert. The correct, legal method for repainting an area with a vin number would be to take the vehicle to a place that deals in vin/compliance etc , they remove the tag and keep it in a safe place, you take the car home and do the paint etc, then once it's done 3 years later take it back to the same vin/compliance place who won't have changed inspectors/lost the tag/ gone out of business, and they refit the tag. In practice, this never happens because nobody knows about this until afterwards Then we have to send them to a vin/compliance place to get confirmation that it is the correct identifier for that vehicle, which can be easy, or a long involved process with forms and approvals from nzta

If you're not worried about cosmetics I'd leave it the way it is. A recently removed and refitted vin tag is much more of a red flag, they are not easy to make it look like they haven't been fiddled with once removed They are stuck on with adhesive so are easy to damage

Nice work! Looks really good.

That's like that from factory on those things

I think the key to making this go better, is to build more boost at the start so it leaves harder, as that was the difference between 12.3 and 11.9 I had a yarn to the guy that built the trans about the possibility of putting a transbrake in it , as torqueflites are generally strong, but have a weak point that can lead to catastrophic failure In first gear, under certain conditions, (and I'm not sure exactly why, I'm not a transmission expert ) the sprag clutch can be damaged easily . Usually from things like A burnout in first gear, where the tyre gets traction suddenly Downshifting to first gear when moving On and off the throttle in first gear Breakages in first gear like an axle, diff etc If the sprag (a one way clutch, that works with rollers and ramps) gets damaged and doesn't work, the forward clutch drum gets to spin 3x engine rpm. They are made of cast iron and don't like that, and they explode . 727s have a bigger drum than 904s so they are more prone to it So anyway, trans guy said you can put a transbrake in a 727, but to get the benefit from it I'd need a looser converter as well which would likely be a custom built thing to suit my combo. For those who are interested, a transbrake works by putting the trans in first and reverse at the same time when you hold a button down- this allows rpm and boost to build by loading the engine against the converter. Turbo cars can also use a thing called a bump box which momentarily releases the transbrake to 'bump in' to the staging lights- this allows you to stay out of the beams until you build boost I dunno if I'll get that serious about it, as it's mostly a road car, and it drives well with the converter it has in it A easy thing to try is a 2 step rev limiter so I got one of those and an adjustable low rpm chip so I can see if that can build more boost mashing the brake pedal as hard as possible

Neat car, I've never seen one before

That looks fun. E&H motors in pukekohe do a lot of tuning/turboing/adding roll cage bars/etc on these things, they may have parts you need?

That will be for repair cert not lvv cert, LVVTA now runs the repair cert system. I believe they intend to run different rules for pre 90 vehicles, in an effort to help people who are restoring older cars as applying the same rules for an HQ holden and a 2020 kia does not make sense

Not usually something that can be certified Because of the extra leverage on the mount points they often end up cracking the arm Ages ago I did a cert on a lifted Colorado that had spacers, I put a gopro on the top suspension arm and it flexed an alarming amount with a ball joint spacer fitted

Yep if it's just a steel coilover body that's fine

Technically, modifying or replacing bump stops with non standard ones, requires cert. But, a scallywag with no regard to following the rules of the land, an outlaw if you will, would likely get away with it if it looked standard. The aforementioned scallywag should be careful that a replacement shorter bump stop still limits the travel before the driveshaft hits the tunnel though

Oldschool drag day '22 edition Did 8 passes Interestingly, every single one was 115mph. Did a few 12.4, 12.3 etc then 3x 12.0 in a row Last pass was near the end of racing so not much time to cool down, I ignored the green and let it build boost with the brake pedal pushed as hard as I could , when I let the brake go it left harder than any other pass today, 11.90 massively stoked with that. I've never paid much attention to 60ft times but it appears that I should, as mentioned all passes were the same mph but the quickest was 1.87 vs 2.3something for the slowest

It's not a requirement, but it can make a cert a lot easier As part of a cert, we have to fill out a "safety items form" which is basically a wof checksheet. OR we can supply a wof checksheet, which means we don't have to take responsibility for those items. Some certifiers insist on it, some do not. There are a couple of advantages with getting a wof check sheet- The certifier doesn't have to check the regular wof items (wiper blades , reverse lights, seat belts etc) so can make the list shorter Exhaust noise is a wof issue not cert, so something which is a bit loud, the certifier can put the responsibility of checking noise back on the wof inspector If the car is a bit of a shitter, same thing, certifier can just concentrate on mods and not worry about rust repairs etc, as it falls back on the wof inspector That said though, I still check to make sure it's safe, even if it has a wof sheet, as I have to road test it, if it has perished brake hoses or knackered ball joints then I'm not going to go hooning down the road and do brake testing in it

Yep that would be fine as long as it's made from a suitable material, has the right design etc (Things like a means of spring location if the spring sits directly on the mount, stuff like that)

Vtnz are the gold standard in vehicle inspection! missed the rust and the fact that the shocks had lost all their damping juices

That has happened in the past, my grandad got sent a voucher to get a new wof check done by vtnz when his local testing station got in the poop

What sort of car? If it's just making a top mount to bolt in a strut that's the same sort of configuration , should be straight forward

Yes, came with pen , and have tested it using 'notes' and it works , I need to find a way of organizing each formset better I'd happily use USB if that was an economical option, I have not checked for ages but last time I did, cd was the cheapest way, ordered some the other day and I think it was $80 for 100 cds I should check how much usbs are now Each job would have to go on its own USB so I'd get through a few of them

There's nothing in the rules here about having mechanical gauges in the cabin, fuel pressure would not be allowed though

Thanks!

I ended up with a galaxy tab s7. There was only two options really, that or a different one with keyboard that was over twice as much $ I looked at Apple ones but immediately got lost when trying to use it also got a cable that goes from different types of USB so I should be able to plug my cd writer into the tablet, I assume there will be some app that allows a tablet to work with a cd drive

Hand writing on to a pdf As far as I can figure, I download the copies of the check sheets from lvvta into the tablet, then I can copy them into a job file for 'x' customer, and write on them on the tablet. Most can remain as a file , but some have to be supplied in physical bits of paper so I can print those ones out Then add photos and burn to a disc which then gets couriered to lvvta for processing Apparently next year sometime there will be the option of sending electronically via a cloud?? but I'm not sure exactly when that's happening. I was going to just stick with the oldschool method of doing it all on paper but I want to get the tablet deal sorted, so when the completely electronic method is available I know what I'm doing, because that will make a cert theoretically possible to do start to finish in a day , rather than 5 days

OK. Went to pb tech, they didn't really have that many tablets to choose from, found a beardy long hair guy who was very helpful. Laughed and pulled a face when I asked if any of them had cd writing capabilities but got the stuff I need, I think. Anyway, next retard question To make a file, for a cert job, I need to be able to import pdfs, write on them, add photos, and put it in one lump of info I can send/put on a cd What's a good program to use for that?
