How Much Power Do You Want

[cdm]

G'day again Peter. I have recently purchased a second hand unichip for an XR6T and am willing to wait untill you start selling the injectors to current phase one owners before I have it installed. Is the price of $1080 for the injectors including installation and retuning the chip? If not, what would I expect to pay for the installation of the chip and injectors including tuning (minus the cost of the chip considering I already have that).  Would the fact that I have the centre muffler removed and the K&N filter help in reducing exhaust back pressure thus reduce the chance of valve spring issues? Thanks.

Back onto the power question. To justify why I would like to pay $5000 for 350kw  is based on a dollar per kw calculation.

Phase 1 = 40kw increase (approx $1650) = $41.25/kw

Phase 2 = 90kw increase (approx $5650) = $62.77/kw

Phase 1.5 looks good at 60kw (approx $2600) = $43.33/kw

hence how I arrived at $5000 for 350kw.

110kw increase ($5000) = $45.45/kw

Obviously it an extremely basic formula and there are many considerations to take into account....ie Phase II is EPA compliant etc (Does this require an engineers certificate? If so, approx how much more is this?). However, this is my personal bang for buck formula which helps me justify the dollars! Thanks for all your input to this forum! I hope to be popping in soon for the injector/chip install!

Cheers,

Chris, The $1080 would be for the injectors only, plus installation of the injectors unichip and dyno tuning/mapping work would be another $480 approx, there is a fair amount of time to do the mapping work with the larger injectors, and auto cars take longer to map than manual cars. These prices are based on a doing a stock car, if the car has lots of other mods then the time frame will be longer and the cost higher.Your price forumla makes sense and on that basis the PHASE1 and PHASE1.5 provide the best bang for buck.There is no doubt that higher power levels cost more on the Kw per dollar basis though this has always been the case and its unlikely to change into the future. IN any event thanks for your feedback and I trust that we can assist you in the near future.

I find this quite interesting given the conversation that we had just yesterday..

Sorry CnC, could you jolt my memory on this one? What conversation?

Cheers.

Peter,

Do you have any details regarding this twin turbo commodore? I assume that you would plan a kit for it, or already be working on something in the back of your mind..

Have a look at: http://www.amberleyautos.com.au

Twin turbo LS1 kit 6 psi making approx 350rwkw or 10 psi making 450 rwkw.

APS, regarding your comment: "G'day Robiie, The only car that I know of (not yet released) that is likely to be competitive in terms of price and performance is the twin turbo Late model camira and its around a year away from release. In the interim period the xr6t is untouchable in terms of value and performance."

Are you referring to the Holden's new turbo 6 in the VZ?

Hi Peter,

On your website you have the Motor Review for stage 1 mentioning that they had the Catalitic converter installed as well as the chip. You have also mentioned in other threads that the back pressure from the engine is one reason to upgrade the exhaust.

Is it advisable to add a acat coverter with stage 1 and what extra power would you gain with one?

thanks

Yes I am though I cant say more on this issue for obvious reasons.....sorry

G'day Geeseman,

The exhaust back pressure becomes a real problem with the stock exhaust system( at over 9 PSI at the inlet manifold ) and can cause valve spring issues depending on how good a condition the valve springs are in, and in some cases cause an engine miss under high load/high rpm conditions.

The motor mag information on our website regarding the cat upgrade is now out of date as we chose not to go that path due to the high cost of the 3.5'' cat.

The only real option is a low to zero back pressure full turbo back exhaust system with a high flow 3.5'' cat converter, as this system not only eliminates the unwanted back pressure it greatly reduces the thermal load on the engine which extends piston and valve life.

If you dont go the full exhaust system route now then I recommend you dont exceed 8 psi of turbo pressure otherwise you may run into valve spring issues.

thanks Peter,

I'm looking at stage 1 initially but then to stage 2 after around 30-40K on the clock.

My idea was to get stage 1 and any other components that are neccessary (perhaps fuel injectors or cat converter) now and then upgrade what's needed to get to stage 2.

Doesn't the stage 1 mod enable 9 PSI at max? If so is the cat recommended even if it's expensive? Id rather play it safe with engine components even if it means a few more dollars, of course.

G'day Geeseman,

We dont offer a cat upgrade only,we decided to go the full monty and designed the best emmision legal full turbo back exhaust system that money can buy, and this exhaust system includes the 3.5''cat converter.

This full turbo back 304 stainless steel exhaust system can be purchased as a seperate product DIRECT from APS.

I would not recommend 9 PSI with stock fuel injectors as the air fuel ratios will be too lean at full power,and as stated in my last post you may run into valve spring issues.

If the engine is in good shape 280Kw should be achievable at the PHASE I level.
