No disrespect but you have no idea what you are talking about on this matter. The only thing that you got correct is the DQ500 is more suitable for drag racing. You should stick to tuning because you have demonstrated time and again that you lack technical expertise in engine and driveline design/operation as demonstrated in other threads here. Just because you think you know doesn't mean that you actually do know. What I posted is correct for those interested in factual info. Use it as you desire.
To be specific 250 ft/lb. torque capacity = 340 Nm - the RATED maximum sustained operating torque capacity for the DQ250 not the CRITICAL torque limit of the trans. 250 ft/lbs. is not the failure point for the trans it's the sustained designed full load operating capacity. The primary limiting factor is the clutch torque capacity and OE clutch pressure. Even with increased clutch pressure the clutch torque capacity is lower than the trans physical capacity - as it should be by design. You want the clutch to wear not the trans to self-destruct. Insufficient clutch surface area is why the OE clutches wear prematurely even with increased pressure in high torque engine applications.
Clutch torque capacity is a function of contact area, disc diameter, number of discs and applied pressure. THAT is why an additional clutch disc is added for high torque applications. The upgraded clutch disc/drum/input shaft assembly which is of superior metallurgy to the OE components will more reliably handle increased torque - because they are properly designed for increased torque capacity above the OE component limitations. Adding clutch discs for higher torque applications is standard auto industry practice used by auto makers as it's the proper engineering approach for increased torque capacity.
Drag racing shock loads can be extremely destructive on OE driveline components designed to last 100,000+ street miles not designed for drag race shock loads. If you're serious about the racing then the DQ500 would be a better choice. For performance street applications an upgraded DQ250 should be fine as long as you're not running drag slicks.
Keep yapping you troll. You don't even know the "rated" limit on the trans
Nope, 340nm is not it. There has been even a VW Golf with 350Nm and up using this transmission from Mk5 to Mk7.
No, clutch upgrade is not needed on DQ250, ever. Again, only people who can't tune do that, which is why almost everyone stopped doing it in 2014 or so, when most people figured out how to make the trans hit 20 bar. There is nothing reliable after 600nm (which the stock clutch is fine for with 0 issues). You will snap the input shaft in half and/or strip the gears inside the box. End of story. Waste of time. As said before, the OEM clutch is not the weak link - but since you know nothing about the design of the transmission it is not in your capability to understand that.
You have never even seen the inside of such trans, never mind tuned one or taken one to it's limits. You can write really long paragraphs of text though. All of which is just misinformation/trolling.
In fact the only reason you registered on this forum is to troll, as you know nothing about tuning. I dare say, you know nothing about anything automotive apart from regurgitating shit you read on some forum, and your experience with the topics discussed on this forum is exactly ZEEEEROOOO.
