Jim, From memory, the markings which the dots on the cam gears are supposed to be aligned with are at 10 o'clock position for the inlet cam and 2 o'clock position for the exhaust cam. Some of the cam gears are designed, so the dot on the gear lines up with the '0', like yours seem to be. With this type, they will look tilted in the opposite direction once on the car. Other cam gears are deisgned so when the dots line up, the '0' will be upright in the 12 o'clock position. If you zoom in the pictures i am attaching you will see what i mean. So, if you had directions from someone with this type of cam gear installed, you can get confused, which is what i think has happenned. In reality, it does not make a difference which way the '0' is facing, but it's critical that you line everything up properly.

Yeah, but it took them 129 runs to get there...

Nigel's result on the weekend was pretty ordinary. He couldn't even crack 500rwkw.

Aren't these worth over 5k from Porsche...? Sounds like an awesome upgrade for a GTR. Good luck with the sale.

Yes, the white plug in the third picture you've posted fits the GTR loom where the factory boost selenoid plugs into. Brown from Apexi to your blue and red to green.

There are a few more but i cant remember now, i will have the car on the dyno tomorrow and have a look. From what i've been told all the factory default settings that you can not access with the handcontroller are pretty spot on anyway. The main benefit of the datalogit is, as it's name suggests, logging data.

None of the GTRs have variable cam timing.

Power Fc has the water temperature correction and it's accessible by the handcontroller. It also has Injector vs Air temp. and Boost, Injector vs Water temp and Boost, Ignition vs Water temp, Ignition vs Air temp etc. but these are not accessible by the hand controller.

Settle down tiger. Having to brand someone an idiot without actually knowing that person is not necessary here. For starters you got it completely wrong. The engine i quoted is a 2JZ with big cams and on 20 psi would inhale 230 lt/sec of air per turbo, not that far from the stock RB25 on 1 bar. That car has also put the power down on the dyno i use and pulled 129mph down the track. I would suggest it qualifies to be a reference point for me. Power is deriven from the amount of air being consumed. If you know the certain variables, why can't you compare two different engines' performances ? For the record, i've never said Rob's car would only have 200rwkw. I said : " On the dyno i use a 200rwkw gts-t will do the same TS." Another with 255rwkw would crack 118mph. Now, from the highly publicised news that Rob couldn't extract the full potential out of his car that night, we know there is more mph in it. How much more remain to be seen but i doubt there will be 7 extra miles in it. Dropping off power during gear changes is a little surprising as well unless the turbine is a real mismatch. In the risk of repeating myself; all this difference of opinion is arising from incosistencies of dyno outputs. Whether it's because of shoot-out mode used or my dyno being conservative is irrelevant. If Paul's title for the thread was "123 mph from stock internals", less questions would've been asked. IMO, the new shoot-out mode is good for dyno competitions and even if/when it becomes widely popular, there will still be some that would not use it. I will try it out next time i am on the dyno, possibly this thursday, but the actual tuning of the car will still be done the old way. The history of my car is in the dyno, as is the number of other cars' for comparison after different modifications. Paul had compared the two below for comparison. 13.8@111mph with 340rwhp - rob77 12.0@115mph with 344rwhp - GotBoost There is a 100kg difference in between the R32 and R33 GTR, is this the case with the GTS-T as well ?

SeriesIIGTSTS, I am not on P's dude. Rob77, I don't have a daddy who funds my GTR either. Just wanted to see who likes to attack the keyboard for a cheap shot.

Steve, You are a pretty harsh judge, i won't be able to sleep now. A brief search on google showed me the flow capability of the TD06, I must say it's a bit more than i thought on paper. In real life i've seen two of them make 535rwhp at 20 psi on 3lt hence the reason i doubted 344rwhp at 14.5 psi on 2.5 lt, with one. The obvious reason here is both cars have been on different dynos and one is reading quite a bit more than what i am used to. Great another skyline driver on P's No wonder the insurance premiums are so ****ed. My comment was put there to see what sort of responses i'd get. Certainly didn't expect you to reply the way you have, pretty much straight after your incident. FYI: I have a maximum no claim bonus. PS: The reason i can't start to modify my car is not because of the insurance, but my dad won't let me before i get off my P's. Denjam, As i just found out, the maximum amount of air TD06 can push on 1 bar is 44 lb/min, but a stock RB25 can only make use of 39lb/min @ 7k rpm. Roy, How much power are you making with the TD06 @ 8 psi and how much did you make with a stock turbo @ 14 psi...?

You are still comparing figures taken on different dynos. How do you know a GTS-T with a stock turbo gets 200rwkw on the dyno i use? TD06-20G can support between 380-420hp at the engine depending on the trim. It is good to see that some can manage this just on 1 bar. No one is looking at the times. His best mph of 111 out of 5-6 runs is a good indication of power unless he was on a leisurely drive. Time will tell whether the 'shootout mode' is the new form of measuring power. From what i've seen so far, we are gonna get figures similar to the ones taken in US from their DynoJets. If you are running the TD06 only on 1 bar, it'd be marginally faster than a well set-up stock turbo; however it would feel quite faster than before because of the way it spools up. Steve-SST, If you think the TD06 is an outstanding turbo good for you dude. I haven't knocked Pauls's or Rob's cars and efforts, if it came across that way i apologise. I've only been commenting on the power figures quoted cause it seems to be a bit high and at every where i look lately. EDIT: And don't you worry, as soon as i get of my P's i will start to modify my car as well.

Being a passanger in a car that's equipped with a Trust turbo like the TD06 may give you the impression that it's fast. Unless he was having a nap on the 1-2 change, a coffee on the 2-3 change and maybe a quickie on the 3-4 change, that 111mph is a good indicator of the power. He didn't have one run and pack up, he had 5-6 runs, out of which the 111mph was the best. 13.88 is obviously is slow for the mph and can be improved on but i can't see anyone else improving on the mph by more than 1-2mph. Incidentally, do you have a graph of your dyno run Rob...?

Dyno Dynamics can run the car all they want, what is that going to prove...? It may or may not be within the limits of the software used. Another car that got 339rwhp = 255rwkw on your dyno manages 111mph. On the dyno i use a 200rwkw gts-t will do the same TS. Until we have a fixed form of measuring power that is used across the country, there is no point in quoting power figures.

For someone who doesn't wanna talk about it too much, you've cartainly explained it all. How many runs have you had all up...? Commiserations on the incident.

Rob77 was going to the strip on wednesday night. Does anyone know what happenned there...?

You can have a good understanding of an ECU's capability by reading it's manual. Power FC manual is readily available on the net, as would be the other ECU's manuals presumably. Water temp compensation means just what it says really. When the engine is cold it feeds the engine more fuel. As the engine warms up it reduces the fuel fed to the engine till the normal operating temperature is reached.

The restriction can be any where in the exhaust, in the form of stock manifold, dump or a clogged up catalytic converter. I used to have it quite severe with the stock turbos and having a little boost spike made the problem look worse. If set at 16 psi, my boost level used to peak at 18 psi and drop down to 14 psi up the top end. It never bothered me a great deal though, as i had a fat mid-range where the shaft speeds weren't a concern and ran friendlier boost levels near the redline. Currently i have the 2530's in place with the HKS dumps and actuators and seems to hold the boost better. Still have a slight boost drop up the top, but this time i think it's being caused by the restriction on the intake, in the way of the stock cooler.

They are making sure everybody understands that SST dyno reads true. As true as it maybe the point is that, others may be using a dyno that reads different, hence the reason the power figures may not make much sense. The shootout mode hasn't become the dominant form of quoting power figures yet. EDIT : Infact, just a few months ago, it was frowned upon to quote power figures in shootout mode.

Ha ha haaa... I love that, bit harsh but funny. "Don't know better" may have sounded a little more unoffensive. We've all been stupid at the start.

Fair enough, your first sentence led me to believe you have a very close to standart hybrid in place. For WIW, i have the 1 bar HKS actuators in place and they don't budge open before it reaches 1 bar.

Restriction on the exhaust side is the main culprit. Since you are using the standart-hybrid turbo, i'd say the exhaust housing is too small for the exhaust gasses generated at high boost and rpm. The wastegate actuator could cause that as well, but since it's an HKS item, it generally means that it has a stiffer spring in place. If it's an adjustable item, play around with it.

I am planning to dude, will definitely have a run on shootout mode next time i strap my car on a dyno.

I hear what you are saying about the gear ratios SydneyKid, but i don't think it is relevant to our scenario. Apart from the LS1 boys with their insanely short gearing in 6th, no one would bother to change their diff ratios on a daily driven car here. Imagine your fuel economy and changing gears like a truck, skipping every second gear. I am very confident in saying that just about everyone here, keep their gear ratios to the factory spec and don't chop bits of their car to save 1000 pounds. If GTS-t VSPEC and rob77 went to the track tonight and didn't crack 123-124 and 117-118 mph respectively, i don't have much faith in their quoted power figures.

Hell of a lot more comparable than dyno readouts mate. Traction has a huge effect on ET's but not much on TS.
