THOR Racing

Hi All, The sheets show FLYWHEEL power but are in fact HUB TORQUE and HUB HP figures. It's due to the correction factor (tcf) being 1.00 that there is NO compensation for transmission losses. If I printed the hub power plots then you'd all be saying "wow my cars got 1280ft/lb torque"..... when in fact that is the torque at the wheels (due to the multiplication factor of the diff). But as usual most people understand the figures when you say "at the flywheel" So the hub figures are divided by the diff ratio shown on the graph. Shame Dynapack don't allow us to change the heading of the page, it'd make things a lot easier. I also think they should make it so the marker indicators where also printed on the graph so you could see what the yellow and green boxes on the bottom of the graph was referring to. Hope you all enjoyed the day. Please email me any photos you have or pictures of your cars if you wish to go in to the hall of fame. Regards Pete

There's a good map on our website Map to THOR Except the flashing dot is the wrong side of the road We're on the left. Regards Pete

Please note the dyno runs for mcanny runs are at three different boost levels. Stock 0.75, 1.0 and 1.2 bar. Pete

As we do more Dyno runs on the Supras at the Dyno day we'll have more of a feel for problems. It calculates engine speed from the rotational speed of the hubs. That's why you have to synchronise the engine RPM with the wheel rpm, this should be the rear differential gear ratio. Auto gearboxes are difficult but under high load and high RPM the gearbox should be locked up by then and the torue converter slip reduced. Regards Pete

I wonder if I put blue LED's on me it'll have the same effect? They do look great though. If there's enough interest I'll look into a less labour intensive way of doing it all. Regards Pete

Terry, Might be worth looking into. Maybe at the Dyno Day. The effect was seen on JDM mainly. The UK car and JDM and VVTi all showed differences but the problem in question was between cars of similar mod level and same spec (JDM) Pete

The other traces (runs) didn't show this so it's either my right foot going wobbly or a slight misfire. I don't think it's anything more than a one off. That's the reason for doing a number of runs to make sure. Regards Pete

I think the circled glitch was a tiny misfire. The other traces (runs) didn't show this effect. The fact the trace goes lean at 4000rpm "I think" is due to the boost dropping off and the ECU removing fuel accordingly. With the boost drop of corrected and the second turbo 500rpm lag fixed I think this will go away. The pressure is the cause and the AFR the effect in my opinion. NOT the other way around. If the pressure was not dropping at the same time then I would agree it's a fueling problem, but not in this case. Regards Pete

I've fixed the dead link to my personal pages. http://www.trlperformance.com/personal and here is the link to my Blue Dash Pete

I think some of you missed my point. All Supras (twin sequential turbos) have a pressure drop and lag between single and twin operation BUT some have a more pronounced delay (500rpm) and a greater pressure drop between turbos. So yes it's a common factor in all sequential turbo setups but it appears to be more pronouced in some, seemingly, same spec cars. Regards Pete

The issue was not the 10.2 it was the 12.5 AFR at high load. ideally you'd be looking at 11.5 AFR on a turbo car on full load. 12.5 was a little too lean for WOT. 10.2 is a little rich but not rich enough to worry about. I wouldn't worry unduly unless it was below 10 and in the 9.5's before I'd have to take action. As a seperate issue...... A few of the Supras were showing signs of late 2nd turbo. A large tranistional drop of pressure between single and twin turbos spooling. About a 500rpm lag in the pair coming on line. Now this was seen as a noticable dead spot in the torque and also a concequential drop in fueling by the ECU. (These were stock cars compared with stock cars) This appeared quite a common fault. I have all the plots and if everyone is O.K. and can send me a photo or your car and reg number to my email address ([email protected]) I'll add you to the hall of fame and you'll all be able to compare different specs of Supras with one another. (Better still if it's pictures of them on the dyno) It was nice to see so many stock cars. I have a good baseline of Jap spec and UK spec cars now. When overlaid on top of modified car plots you really see what mods work. Regards Pete

We'll have a burger van appearing outside after 2pm, especially for you. We've plenty of parking space so more the merrier. Oh and NOD will be there as well please note: In order to process all the cars in the above list we aim to start at 9am. The later it gets the later people will have to stay to get done. Regards Pete

New Rad but is it new rad cap? What about new thermostat? Does it run rough at idle, could be temp sensor? Regards Pete

Vaughany, I notived no one replied so.... I would recommend an Apexi Boost controller and running a max of 1.2 bar (maybe turned down to 1.0bar in hot sunny weather) You'll need a fuel cut defencer as well. Change of spark plug temp grade plus removal of 1st catalytic converter as well. You'll be looking at a quick car then. Later a front mounted intercooler to help cooling. If you need any help contact me direct on 02476 362144 I'm only in Coventry. Regards Pete

Fueling, boost, temperature, torque and BHP. Not ignition. regards Pete

Dan, Pop along and put it on my dyno I've done a few tests of mine with simulated failures, like various VSV's stuck open or closed. Just did mine again and got 375RWHP (so getting better) Wish I had more time to spend on my car rather than customers Regards Pete

The speedo gets it's signal directly from the gearbox speed sensor normally. With a converted car it will be coming from the converter. The odometer also receives the same raw speed signal and re-broadcasts it to the rest of the car (buffered) Is yours a VVTi? The VVTi's are converted by a box attached to the ECU. It is the ECU which converts the ABS sensor signals and sends it up to the speedo head. Different to the ordinary Jap spec car. The Speed signal comes from the sensor up the red/blue wire to the speedo head and the odometer. The odometer buffers it and resends it out to the rest of the car via the pink (silver band) wire. So the pink wire on the cruise, PPS and ECU are all from the odometer. If these fail then it's likely the odometer output has failed or is failing (they are becoming more frequent for failure). The speedo with remain operational as it's unaffected by anything the odometer does. The VVTi is different so the above it NOT true for that car. The speed signal failure is only logged (and thus flagged to the driver) after a period of time or over a certain speed. (Exactly when and where I do not know) 60MPH is also the speed the active spoiler deploys so 1: do you have the active spoiler? 2: does it deploy at 60MPH? I hope some of that helped. You can always via the on-line circuit diagrams on mkiv.com and follow the circuit yourself. Speedo Converters Regards Pete

Sounds like the Odometer output drive might be failing OR your speedo converter box is going t*ts up. (That was me in technical mode) The ODO flashing light is VERY indicative of speed signal faults and generally on Jap imports it's bad conversions. Regards Pete

me...being me.... would like to know what type of HID's they are Are they rebased or moulded units. Do they use the phillips inverter or some other make? You don't have to say who makes them, but I'd like some detail on the quality of them. Plus these are 4500K is that correct? I have a customer wanting some, but I need to be able to give him and more some more info. Do you have any pictures of the kit. (Didn't see one on the web site) Regards Pete
