How Much Power Do You Want

[aps]

So is a Phase II system about the limit for reliability of the drivetrain (trans/gearbox in particular)?

If Iwent for Phase I kit now and then in the future decided to upgrade to Phase II (or maybe higher!) can you give an indication of how much it would cost (presumably some bits carry over).

Thanks for all the info you have been giving us lately Peter, you have really been going out of your way to help.

FALCHOON The drive train limit really depends on the driver and the application. The t5 will cope with the PHASE II power and torque level as an every day car unless you drag race every week. The auto is quite good though it would be worth it to do a small upgrade ( increase line pressure ) on the valve body to help speed up the gear shifts at full throttle. If you do PHASE I now and want to upgrade to PHASE II in the future the additional cost would be $4400 approx installed and tuned. THE $4400 covers the full exhaust system, APS cold air inlet, large bosch 44occ injectors, and high volume fuel pump. Hope this covers all of your questions.

hi Peter is there an aps dealer in wa as I want to upgrade to phaze 2 system thanks.

You could talk to the guys at formaz, and we hope to appoint more dealers in PERTH very soon, we should have done this ealier though its been very hectic over the last 6 months. Have a chat with Kevin at Formaz I am sure he can assist you.

Thanks for the reply Peter. I had a UNICHIP in my old car (AU XR6) and was impressed hence why I am happy to come back to your company. I have noticed you are considering offering the phase one kit with injector and plug in chip in the future. If you go ahead with this, would it be possible for all the existing phase 1 owners to come in and purchase the injectors to compliment there existing chip? If this is the case, what output would we be looking at for injectors and chip? 300kw? Approximately how much would it cost for existing phase 1 owners to have the injectors fitted and chip appropriately retuned. I think offering this sort of kit would be a good way of reducing the stepping stone in price for the phase 2 kit.

On a slightly different not, I think if the phase 2 kit was $5000 and 350kw it would be the  best damn bang for your buck in town! However, I guess considering it has already gone through the EPA testing etc it wouldn't be possible to up the power and maintain the 'mean and grean' status. Thanks in advance.

Hi Chris, we have a real shortage of the injectors currently, though I hope we can supply Injectors sets later this year when supply Improves.The UNICHIP with plug in loom and matched injectors PHASE 1.5 on a stock xr6t wii generate 300Kw. Any higher power level may run you into a valve spring problem as the exhaust back pressure at the exhaust valve is very ugly when using the stock exhaust system. If we had the injectors now for sale price would be approx $1080 inc the dreaded GST.Well we are close to your target the PHASE II is 330Kw for $5650 installed and tuned, need to see where we can find another 20Kw and save $650. Thanks for your input this really helps APS to make future plans.

I'm looking at stage 1 with the plug in loom at the moment. As soon as it's available I will install.

But, I'm very interested in upgrading the injectors when I put in the chip.

What cost are the injectors and how much extra KW would you expect with them and the chip (no extra fuel pump)? Would 300kw be a fair bet, Peter?

I'm also waiting with anticipation to hear about aps' brake package for the T as the brakes blow chunks 

Geeseman, your estimated power level is spot on, the package will be PHASE1.5 and power will be 300Kw. I hope we can supply this upgrade for approx $2600 installed and tuned. Thanks also for your input on the brakes.

CFM I doubt that the muffler mod or air cleaner will produce any power over the stock power output, that said those mods cant do any harm.

Errr - just out of curiousity Peter, if these mods do nothing worthwhile why is it plenty of people here have got dyno sheets showing otherwise?

In my expereince (not with the T) an improved intake especially can give significant improvements in driveability and measureable power gains. Maybe not att he peak level but simply by padding up 'operating ranges'. You even say so yourself that improving these are not a bad thing, so if they have bugger all effect then why are they not a bad thing?

To throw a different spanner in the works... PWR apparently does a bolt in intercooler that has a 1.5lb pressure drop versus the 4.5lb of the stock unit. It's also supposed to be better at cooling... How will that affect a stock T... Especially in terms of throttle response (keeping in mind we have the injectors and the factory ECU still cutitng the fun).... If what I read in other posts is correct this cooler is also quite affordable.

From my standpoint I'm doing intake, leaving the exhaust alone and would consider a PnP loomed chip once things evolve a little more. It's early days in development for all the companies and I think you'd agree that WRX products out now are vastly more capable and better than the ones released in the early years (as an example).

Well that is interesting and I can only speak of our experience,we have tested this combination and it yeilded a zero result in terms of any additional power. I have tested stock xr6t's which have made more mumbo than xr6t's with the centre muffler removed and replacement high flow air cleaner element. I am not saying that these mod's are a bad thing its just that from what we have measured they dont produce the power that some are suggesting and I believe that forum members are entitled to know what we have found. I am not sure on the intercooler issue as you need to look at air temp reduction verus pressure drop reduction to know the entire story. To fit an intercooler without first installing larger injectors , engine management , and low restriction exhaust system in my view is putting the cart before the horse to coin an old phrase. If you really want to improve throttle response and low to mid range torque I would suggest that the UNICHIP combined with a low back pressure exhaust would provide the best result at the lowest cost.

Hi Peter,

My plans with my XRT are either a stage 1.5 or stage 2 APS kit with a PWR bolt-on BA Intercooler.

Will this work? In theory it should as the stage 1.5 & 2 kit come with everything so I can have a proper working cooler.

Has anyone fitted a PWR bolton cooler yet?

Are they good quality?

Sorry Peter I would get the phase3 kit with the APS cooler but phase2 kit is enuff power and the PWR cooler is only $825.

Thx

Hi Peter,

Have you done much work with the XR6 N/A and if so, what sort of power gain has been produced?? I assume a less restricted exhaust would have to be a must in conjunction with a chip even though I would prefer to keep the sound near "stock" because of the large amounts of highway driving I do. Also Hi- flow filter and better air intake would also help I'd imagine.  Would the price be similar to the Phase 1 Mods on the "T"??.

Cheers.

Silverbullet, I have not looked at the N/a xr6,so I cant make any sensible comment to assist you, let me know what state you reside in and I will get you details of a tuner who could assist you.

Peter if the plug in loom needs to be unplugged, does the car need to be returned to the tuner for any other adjustments say if it needs to go back to the dealer for instance

By the way your info is an asset to the site

There may be codes that need clearing, the stock ford computer logs high turbo pressure so this code may need clearing. Most good tuners will have a scan tool to be able check for fault codes an clear codes I know we have the scan tool so it is available.

Peter,

I’d like to comment on your statement in reference to the Nizpro inlet manifold:

Posted: Jan 20 2004, 09:55 PM 

The inlet manifold in my opinion would not improve the response in fact it may very well hurt low RPM torque as the stock ford Inlet manifold is all about improving low RPM torque by a having very long inlet tract.

The inlet manifold is just one part of the Nizpro inlet redesign, and must be put in that context.

An autospeed article (The XR6 Turbo According to Ford –Part Two 22/9/03) sheds some light on the rationale for this redesign.

Autospeed Question:

If you had the XR6 Turbo development time over again, what would you do different?

Answer from Gordon Barfield of Ford:

"Well, we were up against it when we started but I don't there's really anything. If you had more money you'd optimise the intake manifold and probably the throttle body - you'd change its location and the turbo system trunking…. Keeping it simple means costs are kept down all the way along the line to the customer."

Nizpro have optimised the whole inlet, from air box to inlet plenum, and done what Ford would have liked to have done, given time, a design brief and money.

Low end response is better, which is a good result considering a much larger intercooler is used..

Nizpro Stage 2 gets around 280rwkw without having to change the exhaust, which did surprise me.
