I should probably rephrase my post, no Fast N Furious racing here.
How about a short drag race down a straightaway at MSR Houston

The 09 m3 appears to have issues with the tune over 7k rpm. From 4k to 7k it made between 15 to 20 whp more than the higher dyno'ing dinan car on average. The torque was also higher at 261 ft/lbs The proper 5th gear dyno graph with annotations is posted on post number 14. Franklin just didnt have this data, thats why its not in the OP. Once the car's tune gets looked at and the DRF files are analyzed, the car will be run again on the dyno.

For me and many others, this provides value and is something that is fun to analyze and try to understand. If it isnt of value to you, thats cool too. But I think it provided valuable information, and the car will be running better as a result of having run the car on the dyno and gathering this information. I am not sure anyone was trying to make a correlation between dyno power and who is or isnt the best driver or etc on the track. I know I wasnt trying to make that connection. I know for sure I am the worst track driver since ive never done it before lol. Looking forward to getting out there and having some fun! Looking forward to my first time on the track. GSS should be great for those who can attend. Last edited by Black Gold; 02-15-2012 at 08:04 PM.. |

Am I missing something? It seems like the power gains that each modification is supposed to make is not even close to the results shown here. The Turner test pipes are supposed to make "over 40whp" but here it shows only 6whp with a tune. Are the product manufacturers lying? Almost pulled the trigger on a HFC x-pipe, but after seeing this, I have my doubts.

KennyPowers: In looking at your graph, you make HP until 8200 rpms (and then it dips down sharply). You make TQ until 7200 rpms (then it drops down slowly)
On my car, I make HP all the way to 8400 rpm and make TQ until 7200 rpms (then it drops down slowly). I think your car did very well. We basically have a similar torque curve (almost flat until 7200 rpms). As for HP, you being in a manual transmission, I think you should be shifting at 8200 rpms (at your max HP) anyway so you play it safe and not red-line. |

My car over the same interval gained 10whp. Evolve has seen the graph I posted in post 14 and feels that there is something wrong as I do as well. Overall, I really like my mods an even if they can't fix the issue, I still love my car. I like how linear your car pulls and it sounds and looks great. That kind of power curve is going to feel great ad predictable on the track! Are you Going to start tracking your m3?

This was so the point I was making in post #8. Based on my experience Dinan mods are always conservative. Even my E36 M3 with full bolt on Dinan had conservative numbers. But the quality is more important to me. Based on the linear power curve we show, their tune delivers the power the way it should be delivered.....all the way up the band without sacrifice...............Phil

Please don't take my comments as an attack on the manufacturers or anyone else. I own a M3 myself and I also modify my car. I just need credible answers if I were to continue buying performance upgrades. I know this forum is full of very knowledgeable owners. I hope you guys can chip in and explain to less experienced folks like me why this is so. |

second of all, what franklin was saying is that not all m3s will dyno the same baseline numbers, even if they are stock. it is extremely likely that my car for example and richards, if both stock, would not dyno the same power. look at the huge variation in numbers from stock dynos that are posted on this site for proof. more proof is that both dinan cars had the same mods and didnt make the same power. if all m3s made the same power, such a variation would be impossible. finally, it seems like you didnt read post 14 in this thread. compare the power under the curve between the modded cars and stock cars at all RPMs. this is what was done in post 14. you can clearly see the difference in power. it is possible that the 09 m3, with modifications to the tune, can make upwards of 360 SAE whp by making power all the way to redline. this is yet to be seen, and the car will be taken back to the dyno to see if we can make it happen. not to mention that franks car makes 20+ SAE whp (which is not what most manufacturers use because SAE is more conservative and shows lower readings) more than the stock car at redline. this is not an insignficant gain.
