That goes for differential, gearbox, and engine. If you can make the power AND keep the thermals within original limits, you WILL last the distance. Word of warning though, its not easy! So your saying as long as I kept all the tempertures at factory levels for diff and gearbox then potentially the drivetrain could handle 1000ft/lb of torque? Generally gearboxs are rated for a set torque, go over that and the life is reduced, doesn't matter how much thermal control you want to throw at it.

It would be nice if you could add something constructive to this thread. Your picking at my posts wont help those like CnC who wanted some straight answers. My statements on durability are constrained to the usage of the standard compressor, and the experience gained with the car so far.Please feel free to share some of your own experience with us at any time.

Guest Fijneman Guests Posted 13/04/03 04:43 AM Share Posted 13/04/03 04:43 AM Well I'm sorry if you don't find my questions constructive street tuner, perhaps that’s why you never seem to answer them. Coming from an engineering background I can see a lot of floors in your logic and I merely would like you to explain why. I don't see this as being non constructive, only your silence is non constructive.

Other than that, not that I am currently aware ofI actually meant in the boost control department, I had an idea that Ford might be controlling how quickly the boost comes on via eletronic boost mapping.. I assume you guys are playing with the signals coming/going between the ECU and the wastegate actuator you may be able to change this to some degree? Quote 4) There is obviously more left in the engine. Probably not left in the turbo. Rather than try and optimise the 240T for big power we have instead concentrated on maximising Nm at 3000rpm. I wouldnt be too worried about the strength of the internalsWhy wouldnt you worry about the strength of the internals? Not being picky but do you have any information from testing or is this just a gut feeling.. I have spoken to one workshop in particular who think the rods are very thin, and the valve springs are prone to breakage, even with stock RPM limits.Assuming the engine internals are not limiting what would your next step be? I assume you would add the biggest FMIC you could fit in, add a turbo with %20-30 more airflow, change the inlet manifold and inlet piping to higer flowing items, add a T56 six speed manual gearbox and uprated clutch. I would assume this would require ECU modifications of some type, or a change of AFM? As an aside what does the AFM read at peak torque voltage wise..?PS: Some nutters out there will want to go a little more crazy than everyone else, and yes I am one of them Fijneman:I think its obvious that the gearbox is not going to withstand 1000ft/lb of torque, but as you claim to be from an engineering background I'm sure you would know that most components are rated conservatively in terms of what they can really handle.. and OEM's are naturally very conservative to be 110% sure that few warranty claims are made.Although the gearboxes may be rated at 450nm or whatever, keeping the fluid temperates in check will help greatly when pushing them slightly over their rated specs by 30-35%.

Street Tuner Member 727 Member For: 22y 5m 6d Posted 13/04/03 06:34 AM Share Posted 13/04/03 06:34 AM The boost comes on as quickly as the turbine allows. There isnt a whole lot you can do to improve this threshold without changing hardware. As for the engine....the size of the rods doesnt bother me the slightest. I am not aiming to rev the engine any harder than stock, and the power loading component is negligible. Remember, boosted engines, as a rule, are very kind to conrods. You seem to have a handle on the rest of it Link to comment https://www.fordxr6turbo.com/forum/topic/1613-capa-performance-parts/page/3/#findComment-17175 Share on other sites More sharing options...

The car will always react to the way the rignt foot is used. For my 2 cents worth I think the formula for Turbo success is pretty strait forward. Good components a little boost (Remember after a certain point boost any higher will not give you any more power) Make sure you have enough fuel and let it breath and presto have fun. At the end of the day as long as the car isn't pinging and you are not stupid and launch at every light you stop at, you should have a nice reliable, quick car Link to comment https://www.fordxr6turbo.com/forum/topic/1613-capa-performance-parts/page/3/#findComment-17182 Share on other sites More sharing options...

Its a case of intercepting and processing signals (but not just in an analog fashion), minus all the 'smoke and mirrors' being currently flaunted by various companies in an attempt to gain greater technical credibility in the eyes of the public. I have been trying to 'crack' the protocol for serial programming the standard computer for several months now. No one is any closer. That I can assure you.The healthiest and happiest XR6T combos will have the greatest control left to the stock computer. Fact. It knows best the ignition timing, which is adaptive, and trimmed both long and short term. I believe that there would be more power in my care with an EXTRA couple of degrees timing, not any less. I assume if you’re trying to crack the serial programming protocol, you are an electrical engineer? Also can I assume that if you haven't 'cracked' the protocol, that the jointly developed capa kit with your technical knowledge doesn't change the air fuel ratio or ignition timing, in other words, lets the factory computer sort it out? I realize the xr6t computer is adaptive but even adaptive systems get it wrong, especially when there not running factory conditions.
