Based on the Stage 3 graph (Engine figures; subtract 60kw for rwkw), published on the APS website, it looks like the power graph has been flattened out to perhaps protect the gearbox.

Brian,

That was a perfect example of how not to extrapolate wheel power from flywheel power - in order to compare two different products.

Here is a graph showing power at the wheels of the APS PHASE II and PHASE III systems - on the same car - same dyno (shoot6).

To avoid any further confusion, I'll have the PHASE III dyno chart on our web site changed to show wheel power.

The PHASE III system is awesome right from idle through to redline and is currently the quickest XR6T in Australia - 11.28 sec @ 121 mph. and also the fastest 4 door sedan in Australia as tested at 307 kph (with 3.23:1 diff ratio) Scores on the board speak volumes!

We don't just talk about performance, we live it.

It's all about delivering power and torque where the engine and entire drivetrain will be happy, emission compliant and an excellent every day drive.

From direct experience, it's a lot easier to talk about it than it is to do it - but nowhere near the fun!

It seems its also easier to use cliches than it is to provide answers to perfectly reasonable sensible questions...although, credit where credit is due, you did get 3 in a pretty short post!

For the 3rd & final time (see I can do cliches too!)

"Do you bring the boost on very slowly & only ever give full boost at the top end of the rev range so as to manage the torque?"

OK Peter, we have all read the marketing before.

edo and bcl have, what I believe, valid questions....

Thanks edo, they may be cliches though they are also an undeniable facts.

Its really very simple, just look at the dyno graphs on our web site. They show exactly how and when torque and power is achieved across the rpm range. It's not possible to make this any clearer. We are not simply looking at turbo pressure in isolation, for to do so would be foolish.... Rather we consider the torque and power curve that best suits the dynamics of the car.

If you want to know more, or if you would like to give me a few pointers on tuning, attend one of the APS unichip DEMO and information days posted in the events forum. I am sure we can all have a laugh. :lol:

PS We're off for real racing now - to give the keyboard a rest. See you guys out there.

Trumpy, the marketing is generated from engineering, research and development - and in-field testing of the product. It's based on fact and data. What more can I say.

I trust that my previous two posts answer the questions regarding power and torque curves - as this is what counts in the real world - on the road.

Hahaha, Im not suggesting I know more than you...in fact Im asking a question that I dont know the answer to but think you might.

Im taking that answer as a "yes the boost is increased slowly through the rev range, only giving full boost up top but we also fiddle with timing & fuel delivery (maybe cam timing too? dunno. Not expecting a answer)". Im sure I'll be corrected if Im wrong.

On the road eh? In an unregistered car? Naughty Naughty!

that's cool Peter,

Just want to keep this one on track, that's all.

Thanks Peter for at last answering the Q I was the first to put quite some while back - and thanks to the others who kept prompting for a reply.

So, ... the Supra box.

If I remember correctly it's a Getrag? Also if I remember correctly (it was a long while back that I studied the spec for this box) it has a very low first gear and a fairly short overdrive on 6th gear only. Therefore in the T6 I would expect a diff ratio change to a very tall 2.72 would be called for. This puts extreme loads on the driveshaft components, unis etc.

In my assessment the box would be more suited to a lighter vehicle, and also to an engine that has not much low down torque but lots of revs to play with. NOT A FORD MOTOR!

As I said, I may not be remembering the specs properly but I do remember that when I was looking at a replacement for the TR3650 in my T3, I discarded the idea of the Supra (Getrag) box for some good reasons or other. I extrapolate that, if it was not suitable for the torque characteristics of my ol' Windsor, then it won't be suitable for the T6.
