Hi SAU

I am in the process of manufacturing a universal trolley jack pad, intended to save pinch welds from bending and wear when using a trolley jack from the side lifting point.

A picture of a current sample has been included below, the final product will be very similar to this. It is to be made from polyurethane perhaps with small amount of rubber in the mix for various reasons, the exact chemical composition is still being decided. I expect the retail cost to be somewhere around the $12 mark, every effort will be made to minimize this as much as possible without compromising quality. It will come with a warranty of which the details are not yet decided upon.

I am hoping to enlist to help of SAU to check the compatibility on as many makes and models as possible, I am also wanting to gauge potential interest in the product.

The pinch weld slot is 10mm wide and 25mm deep for compatibility reference

Any feedback would be much appreciated.

- Michael

Great to hear Jordy32, hopefully they will be ready for sale soon !

Scotty nm35, anything is possible given enough time and money :) however these pads are injection molded requiring a rather expensive die. An adaption of this for use with a hoist has been mentioned to me before, so this may be likely in the future.

Thanks junkie ! That's actually how this product was born, I needed one and couldn't buy it !

The ice hockey puck is a great idea, in fact, at least two places sell exactly that as a jack pad at a crazy price. The only problem is the thickness of the puck, it doesn't allow a deep enough slot for many applications and vulcanised rubber is much more likely to split, wear and be degraded by chemicals than polyurethane.

I made some of my own a few years ago out of various different plastics, when i went to to take a photo i could only find 2 of them (think i made 4 originally), my main jack has a rectangular lifting pad rather than the usual round ones, so i made the width of the block to suit but it also works on my other 'round' jack aswell. from memory the slot was 12mm wide and 17mm deep.

They work well

I have also thought about a product like this, but I'm lazy and never done anything about it.

Some suggestions if i may?

Make the grove shallower, if it's not deep enough, no harm done as you're still lifting from where it's meant to be.

If it's too deep, it will lift from the body where the vehicle is weaker.

Make the locater round, but make the lift/pad longer.

Same weight over bigger area is less lb/in2.

I find that's the biggest issue.

If you spread the weight out, it really helps the sills.

Hopefully make them chemical resistant.

Use around oils and fuels, this would nearly be a necessity.

And last, don't sell too cheap.

I'd pay 20-25 bucks.

Take the extra money, and put into more products.

If you dont like my ideas, then maybe I'll have to release one :P

Either way, I wish you luck and hope to see these for sale soon :)

Thanks for feedback and encouragement everyone !

Gza36 - Thanks for the information ! Very helpful !

luke gtr - Glad to see I beat you to the punch :P Thankyou very much for all the suggestions ! As you say chemical resistance is very important, which is one of the reasons why polyurethane was chosen as the material, rest assured it will stand up to the rigors of a workshop. An enticing option to increase to cost I must say, I originally had a cost of $20 in mind but I would like to keep it as low as possible, we shall we what happens when the final cost is decided upon. You will definitely be seeing new products in the coming months and years though !! Thanks again !!

Terry_GT-R34 - Not a problem at all, thanks !

For anyone interested email me at [email protected] to keep informed with updates and possible release dates !

      Behrman is great quality stuff. My 34 has some serious clouding as well but I’m too nervous to try and replace the glass myself so I haven’t bought them yet.

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      This might be true if you live in NZ but I can't see how this could be true for us locals here.  I've found the customer support for Haltech to be absolutely amazing. I've turned up to Haltech and spent entire days with their tech support guys, they've even helped me with wiring dramas that had nothing to do with their products.  They have the best customer support of any company I've dealt with, I can't imagine how my experiences with them could possibly be any better.

      If you want to do a single throttle body conversion easily, you won't need to pull anything apart. Take the linkage from your throttle off the linkage controlling the ITBs. Now open the ITBs wide open, and lock the linkages in said position. Now add a single throttle body onto the front of your inlet plenum. No it's not ideal for the last nth of a kw, but it'll be a lot better than what you're already trying to do...   PS, ITBs can be so damn hard to tune from, because roughly 20% movement in a throttle body equates to a change in roughly 80% of its flow (Hence power). When you add up the flow limitations of those small throttle bodys, it is a LOT higher than that of a single large throttle. Hence, TPS is very very sensitive with them, and you do a LOT of work with sensor fusion, and some Maths behind the scenes to make those blends nice, and be smooth.

      Yep, when Haltech purchased Adaptronic, and all of the Adaptronic staff, including Andy went with it, it took Haltech to the next level. Haltech wanted Adaptronic as they wanted things like Andy's fuel models, and some other IP, AND they wanted Andy too as he is brilliant! Andy has spoken about the incompatibilities between the old 1500 stuff vs Nexxus, and it totally makes sense. It's not JUST software that is different, there is huge changes in the underlying hardware too. It's why Haltech has had soooo many changes in the last couple of years, in terms of Hardware, and Software, and why it has become so damn Amazing. Why do you think guys like Rob Dahm with his quad rotor, went from running Adaptronic's to running Haltechs? Andy. Pretty much, Haltech these days, is Adaptronic, but with more funds behind it, and more staff, and hence Andy's visions, and visions of other people that he helps shape their great visions, into amazing new products. All the new Nexxus gear, whole new software for it, new and better dashboards, the apps that will run on headunits and NOT be slow to respond! I understand people being burnt in the past, but if you're ragging on a company, about products and issues from many years ago, it's more a reflection on yourself, not looking or keeping up with new stuff. In which case, those people should be going back to PowerFC and Nistunes as the ECU's to rave on about...
