How Much Power Do You Want

[Turbo6man]

Sooooooooo.......um..........How much power do you want?

Oh yeah, the topic ... hmmm, enough is NEVER enough !!!

I'm impressed by the figures already achieved at this early stage of this engine's development life.

IMO the chassis, brakes etc is probably limited to about 300kw. Any higher than this and you would have to be a careful driver, concentrating 100% of the time to fully utilise the power available - I'd therefore probably rather have 300kw and be able to drive it to it's max easily and consistently.

EG with my ZL it is really hard work to control the vehicle when I have the wick turned up to 12 psi or above. So I leave it at about 7psi and it still blows away most things, and without any dramatics or excessive smoking of the rears.

I had the APS stage 2 installed this week and it's great.

Not as much of a dramatic effect as I envisioned, and it sure feels like the chasis can cope with a bit more than this! Premium brakes, so no problems there.

I'm waiting for stage 3 now, that should be enough! (For a while). :lol:

Good to see the phase II system installed and I trust that your happy. If you have a chance let me know who did the install and were you satisfied with the customer service provided.

Thanks

one question APS, if you replaced the factory cat with a high-flow 3.5inch job and a 3.5inch downpipe, but left the apperently high-flowing standard exhaust would that be good enough to make 330kws with fuel pump and injector upgrade??

Dave,

I doubt that we could make the 330Kw as there is 2 psi back pressure in the stock exhaust exhaust system (after the cat) at 240Kw, at 330Kw (if that was possible) the back pressure would be very ugly and start to cause valve spring problems.

This high exhaust back pressure is very tough on pistons,valves,and the cylinder head, as the high thermal loads are the result of a greater volume of hot exhaust gases which can not be expelled quickly enough as a result of the restrictive exhaust system.

Bottom line is you dont want any exhaust back pressure in a high powered turbo engine if you can avoid it. I would not recommend this path as it will lead to premature engine problems.

I've gotta Ask.... But what does the Ford Dealer think of the mod's??? Such as a APS Stage 1? Or removing the muffler.

And what/how do you insure a mod'ed car? Do we tell our insurers? or Not?

These two questions is why my current thinking is to wait for the FPV-T - but you guyz could convince me otherwise......

Cheers.

Hi ThinkinMan,

Your Ford Dealer would probably secretly be drooling over the mods - mine did. They're flogging $75,000 GTP's that are two seconds slower over the qtr mile than mine....

The APS Phase I and maybe even Phase II are quite stealth and unnasuming (ie, the mods aren't very obvious) so you could get away without telling anyone. I would strongly suggest you tell your Service Dealer that you have or are getting the mods. After I told mine, they said they would still cover most repairs/faults under warranty (And the Ford Motor Company wouldn't need to know), as long as I didn't show up with a blown gearbox, cracked diff etc etc. Drive it reasonably, and they'll look after you...is what I was told.

I gotta raise one point though. If you are adament in making sure you're 100% covered by warranty, and aren't willing to dip into your wallet in the event that repairs needed from the extra power - don't tune your car! You can't have your cake and eat it too. The APS Phase III is almost twice the power of the factory stocker, and I'd be freckin' stupid to expect full warranty cover from the factory when I've 'roided my car like that.

Insurance on modded cars? You'll pay heaps, and some won't insure you at all depending on your rating and age. I switched my policy to Shannons, after RACV said they couldn't cover me once I went Phase II. I told Shannons I'm making a 10 seconds streeter, told them about all the work done to date, and they insured me. It's costing me $2000 pa but gives me peace of mind.

Bottom line - don't mod your car unless you're willing to dig a little deeper into your pockets come service, repairs and warranty time. That means sh*t, when for under $6k your T becomes an M3 and Porsche killer....

Hello Peter

Wanting to know how long does it take to do stage 1 mod

Thank you for the time you have given us

Hi Peter, you state that after the cat there is 2psi of back preasure at 240kw. I have a couple of questions.

What is the back preasure of the standard system with the standard cat and would you know (or have an educated guess) at what the back preasure would be of the standard system with the centre muffler removed? In the original system is the cat the biggest restriction or would either the centre or rear mufflers be more restrictive?

With the APS scratch and dent exhaust is the $2000 including fitting and if so are there any left?

Thanks Geea.

G'day rapt

Phase I takes approx 5 hours from start to finish based on the car being totally stock which includes before and after power graphs.

A longer period is required if there are other mods on the engine as you need more cool down time between dyno testing as the engine is making higher power and generating more engine heat/temperature.

Let me know if you need any other information.
