Guys I believe @335iRlz has good points and for me it doesn't matter if he is young and does not have much experience like you.... I still like this kid ... he looks educated
First of all your cars are not the same! @boots has some modifications and you never know how that mod changes the torque/power curve! Second, the results tell me the Dinan tuning has more power and torque (compare to stock) at high end and that's why they claim PEAK hp and torque!! the stock M5/M6 has a flat curve of torque between 1500-5750 RPM and then the maximum power happens between 6000-7000 RPM where the torque curve is falling. I guess Dinan changes this map and produce the PEAK torque that they claim at high RPM (somewhere between 5-6k ) and not everywhere like a flat curve between two points. when you are running 50-60 mph in 3rd or 4th gear, the maximum torque is not achieved yet because the RPM is far less than that peak point... Also to understand the maximum speed for each gear, here is the calculation link... http://www.dragtimes.com/gear-ratio-...tton=Calculate with 7200 RPM (redline) and gear ratio of 4.81/2.59/1.70/1.28 and Final drive ratio of 3.15 the maximum speed for the first 4 gears can be calculated: The maximum speed for first gear is about 38 mph The maximum speed for second gear is about 71 mph The maximum speed for third gear is about 108 mph The maximum speed for fourth gear is about 143 mph As an example, at 50 mph the RPM will be around 5K (2nd gear), 3.4k (3rd gear), 2.5k (4th gear)... as you can see at 3rd or 4th gear the available torque/power are in the middle/low end while in 2nd gear they are close to high end and the maximum power (and torque) are almost there! My point is the maximum power and torque that Dinan claims (if they claims correctly) are available somewhere specifically close to high end and not necessarily every point of power/torque curve has better performance than stock M5. BTW, I'm happy you guys had a great day and enjoyed your run

If you guys meet each other again just try something like this and let us know how Dinan works since there is no dyno result available starting at 30 mph in first gear and 50 mph in second gear and 80 mph in third gear... I personally would appreciate you for reporting the results

For the record: We just wanted to see how these cars pulled against each other in a specific gear and speed. Not a "race" if you will to see who could embarrass the other. We were testing. We both know where the sweet spots are in our cars and know how to drive them which needs no explanation. As mention earlier by wrsbmw, his car lugged while my car did not. Our results are not intended to downplay or bash Dinan products, but to point out today's specific tested result. By the way, I am proud to be one of the old cats at the tender age of 48. I was playing when I said I was 17. (Thank you m6-coupe ) The regulars here know who I am and what I represent. We will have much more results when spinny gets his car here and we test. After testing various ranges, we can race from the best gear/tq range, or from the dig. We will do this w/o bms and w/ bms installed.

Wow guys
unexpected results! I know dp's add a lot and rpi straight-pipes as well, but this is a joke, if you pay 10K for the looks under the bonnet and gains after 140mph... now i feel very confident running against manhart m5 and some evolve tuned m5, when i get my bms. both guys claim they have over 700hp and manhart guy claims he has fastest in UK i am hoping to prove him wrong, as he spent a lot of $$$ as well and car went to manhart (germany) at least 4-5 times already in past few months. looks like something wrong, but he only says they are adding more power every-time LOL! he also has 5kGBP manhart bonnet, but i doubt it adds any power will keep you posted evolve one spitting flames like hell have a look http://instagram.com/p/q4aGXtrHby/?modal=true http://instagram.com/p/rNPzUwLHTa/?modal=true update: called evolve and had following conversation: -hello... -hello -wonder what sort of power upgrades do you offer for f10 m5? -we offer ecu tune -full reflash? or piggyback? -full reflash, sir! -so you have broken through the ecu and have full control of it? -no sir, as you are aware nobody has managed to break the ecu and there is very limited amount of access we have then it went on and on, maybe he doesnt know the difference between piggyback and ecu reflash, but all he told me is that it costs 1500gbp (not sure including or excluding VAT), no warranty provided and it brings the car to 620 BHP!!!! as we all know, stock m5 has close hp to that number, so i wonder what you are paying for and on top fo that they can get rid of CEL with lambda sensors Last edited by mstmng; 08-04-2014 at 04:57 AM.. |

I'm not sure how they'd change the curve since they have limited to no control like everyone else :/ I'd ask either one to find me videos on youtube where people were putting in the description "Both cars were in gear 2,3,4,5,6" lol it doesn't exist. And even if this is for pure "testing" methods 4th gear isn't even the 1:1 for the car, 5th is . No way to ever justify being in 4th below 70 aside from "I wanna do it how I want" which is fine by me, as I said all along, use your car however makes you happy, I sure did and do. I don't care how much money I've blown on cars I'll always feel bad for myself or someone else when they spend their cash and barely notice anything, which it sounds like this is the case. lol really guy...

I am not interested in DIYing a 6 figure car to make it go faster, so I don't want to do the BMS for that reason. I went with Dinan because I did get a lot of low end on the flash stage 2 for the 535 just a year and a half ago. I don't think I am going to get it on this car but if BMS does, then Dinan should be able to, but that may not be what they sought to achieve. However, I think I should have asked more questions before spending the money. If I can get the top end limiter removed then this may still be a good combo but I won't win any roll races with it. Unless of course there is just something wrong and that hasn't been ruled out yet. |

I know ... and I know you were not intending to crash their party
Your points are valid BTW, I met a kid driving M4 at stoplight last night and gave him a little lesson not to even bother himself to play with big monster S63tu

http://www.6post.com/forums/showthread.php?t=1017599 Guys, don't get me wrong. I'm not here to defend the Dinan FYI, My car is stock and I'm not gonna do any modification since I'm not a race car driver and I'm not gonna track my car and 600 HP is enough for me especially when the traction issue is already there . I also don't believe tuners unless I see some technical data if they provide (like the curve I explained) . To me putting that much stress (600+ tq) on a transmission that is rated to 516 ft-lb, is not good and that's why the other day I sent Dinan an email and asked them to explain how the car can handle it... no response so far

What the complainer did was only post a short snippet about exactly what happened and he didn't elaborate much later. What I got is that yeah, the son's car won but only by two cars and not until 145 or so. This is more or less my experience with boots but not all the way through the gears, we still need to do that one. |
