  1. More or less my thoughts. Guess I will see if I can clock the compressor housing where I would like to and still get a favorable angle on the actuator rod.
  2. Question for those in the know. I have been running through a long electronics upgrade on my track car over the last couple of years. I am finally getting near the end of the tunnel. One thing I am looking at doing as part of all this is re clocking the compressor housing on my car (GT2860RS turbo) I have never been all that happy with proximity of the discharge to the exhaust manifold. The question for me is, is the angle made between the actuator rod and wastegate arm all that critical? I have seen some on quite an angle but to me is it asking for inconsistent operation as the effective mechanical advantage of the actuator changes through it's stroke. I can get it reasonably straight but not quite as straight as it is currently or the discharge is going to hit the strut tower. I am hoping to be able to get it to form more or less a right angle when closed, but am I being unnecessarily fussy? Before anyone gets worried about changing the geometry on anything stock'ish. it is a track only car and will be running closed loop boost control and everything else dealing with boost control will be new so it will all be set up from scratch, one of the things I hope to do is to be able to run a wider range of boost pressures with a two port actuator and three port solenoid (Previously pegged at 18PSI with a basic boost tee as the old ECU was really bad at boost control)
  3. And for CAMS sanctioned motorsport at least, unless it is set up as an oil separator returning to the engine via PCV applied to one rocker breather and the bottom of the can to the other rather than a catch can (So manifold vacuum when off throttle draws oil back in via the breather) any RB turbo will need at least 3L capacity. I am just about to build a new one for my HR31 and will be making it about 3.5L with an oil return to the sump and a proper filter on the outlet, one track I run at makes the 20DET hoist a lot of oil out. Hard braking followed by a very hard right hander and immediate full power twice in a lap, it spits out up to 500ml in a handful of laps, take it to Phillip Island and it did not put that much in the can over 500KM. You are not particularly likely to get pinned for it being to small at most track days but who needs to give a grumpy scrutineer something easy to knock you back for.

    Biggest thing I would say would be to download the software for each of your candidates and see how you like working with it.

    The only two I have seen are the MoTeC dashes and the AIM ones. Both are a pretty polished product. OBD is good for display but not apparently much chop for high value logging due to update rates, if the system has CAN in the background and there is any chance of sniffing out the CAN messages later to pick stuff up at much higher rates then IMO the MoTeC dashes have a much easier interface for building CAN templates to hoover up whatever data you can get your hands on. There are undoubtedly others but I don't have any experience with them, I would just stay away from Racepak, I think the IQ3 is built too lightly and is getting old, the software is ancient, the dashes are not all that flexible configuration wise and to be plain, the proprietary Vnet concept shits me up the wall.

    Yeah, per a post above, a mate has an AIM dash, he is having issues with data not being shown but if you are doing something over CAN with a known message set that should be a non issue, or direct inputs (DO they have AV and digital inputs?) Aside from that it is a nice looking unit. Except for the money stacking up a bit too much I have considered a handful of AIM smarty cams using their bridge to enable camera start/stop with the logger running signal from my C127. My budget just does not stretch to the MoTeC cam systems, particularly as I would want more than one. I currently have a kludged setup where the logger status triggers an aux output on my dash which controls a 12V relay which turns on power to my camera, that is a Replay XD and is configured to power up and start recording when external power goes on and stop/power down after it goes off, saves forgetting to start and stop it! The bugger is it is the only camera I have found that will do that (Other than off the shelf dash cams which will probably have rolling shutter effect from hell!) and having tested the water with one and found it works how I wanted it seems that Replay have gone belly up and I have had no joy getting any more.

    I would not be too concerned about the lack of an MT forum. Take a look at the Racepak forums for an example why. Loads and loads of questions posted, most of which never get a response of any sort. IMO they would do better to close the forum down as it detracts from their reputation to have people asking for information and generally getting none. If you trawl back enough you can find one of the Racepak guys telling a poster that the forum is intended to be a USER forum and that Racepak don't actively monitor it nor feel any compelling reason to help the users in that way (That last bit being my interpretation) The default response if you get one at all from Racepak is "Call us" which is not a whole lot of good from half the world away. Lack of local support (For any Racepak product repairs Haltech will have to send stuff back to Racepak anyway) was one of the bigger reasons I sold mine.

    I would put up a different perspective (Especially if you are not generally locking them up) Firstly, what they have posted above, shoes. Race boots are not all that costly, buy some if you can afford to. They really do make a difference, apart from anything else the heels will be rounded where many shoes have a much more square heel and it makes things easier, as well as the softer soles helping with feel. The disadvantage is that the thin and soft soles wear out a lot faster than a pair of runners. Second is more of a comment. I found the Skylines brakes with good pads (HR31 with R33 GT-R Brembo fronts and GTS-T rears) to have far too much initial bite which made them easy to lock up, particularly in the wet, you literally had to be on your toes. I went to a 27mm (I think) master cylinder from a Navara and adjustable bias valve to increase the pedal effort but I still did not like them much. I am in the process of fitting a full pedal box to mine to get rid of the booster completely. I was using Project Mu RC09 pads as one track the car is run at is seriously hard on the stoppers and anything less tended to run out of pad fade wise by the end of a three hot lap sprint and consumes the pads at a silly rate. That is on the RAAF base at Sale and having driven both it is as hard on the brakes as Mallala.

    Provided you could still stroke the brake master cylinder to the stop, is there any adjustment left on the clevis and pedal stop to lower the brake pedal a bit? You have to adjust the pushrod and stop (Probably the brake light switch) at the same time. If you just adjust the stop you wont uncover the fluid passages in the top of the cylinder that go to the reservoirs. Basically the piston in the master cylinder has to be right at the top of its stroke when your foot is of. I only put that bit in as a lot of folks don't know about it and it is important to get right.

    Hi Mike, I assume you would be aware of the Prince register? Jason as listed in the post above yours would be a great place to start. Lots of really passionate Prince guys there.
  11. A quick question, can you get spare parts? I have a set of APRA spec Yellowspeeds on an N15 Pulsar and I like the top spring plate design with the integrated bearing. Just interested if the top plates are available as spares so I can look into if they would fit in the coilover setup I have in another car? That is currently using VS Commodore strut bearings between the spring and top plates but they are exposed to dirt.

    As someone who flat refuses to pay money for Rupert TV (And the only thing I would watch on it would be F1) it is a sad reflection that the pinnacle of my F1 coverage for the year is a telecast including a three lap ad break six laps from the finish. The only way they will get my eyeballs back will be if I can dodge the geoblock on the new streaming service (Or they launch it in Aus, presumably the Ten deal, now novated to Foxtel prevents that until it expires)

    To comment on blackrex's post above, yes, it is simple to deal with custom messages. I have done custom messages both in in my PDM and my ECU for the dash and it was no problem to get them working correctly. One was a counter in the PDM to act as a brightness control for the dash (Easy, counter from 3 to 10, incrementing and decrementing with keypad buttons, defaulting to 6 on power up with the value sent on the CAN bus) that is a simple message with a multiplier of 10 to tun it onto a percentage for brightness. The other being a "Fuel used" signal from the ECU to increment a fuel usage value in the dash. Likewise a pit lane limiter signal out of the PDM that turns the limiter on in the ECU but also changes the way the dash behaves. I would hate to go back to something less sophisticated now.

    Sweet, I will grab them when I get home. Haltech are remarkably reticent to release them, the only one I had seen was from some years ago and apparently quite obsolete with a number of new or changed messages. Now I wish I could just find the CAN message set for a Madza 3 MPS. A mate has one with an AIM dash in it but very few of the parameters that were advertised as being available for the car (Which led to him buying the dash) actually appear. I may have to go CAN sniffing for him and that will be time consuming to say the least. He want's to do proper logging so he does not really want to go OBD2 and low data rate, through it might be better for him that when he has now, he is only getting very basic engine data, no boost pressure etc.

    It is not in the C127 manager. I just downloaded the latest one today to check if they had added it. In C127 manager they have the old V1 message set as a compound message, or as individual 4 channel messages on 010, 011, 012 hex etc. Not that it matters to me (I have an Emtron KV8 ECU) but what MoTec software is it in? I occasionally get help requests from mates.
