Noooo..
I am sure there are more people who want to be part of the club! So can we have a conversion factor for dyno dynamics guys who can joint the club too? LOL |

Nice try all of the new kits were done on a 3rd parties dyno not our own. |

This thread is extremly intresting.
I have a dynojet bench but for bikes and we run a lot of bikes every single week in it. We are having the same problem as we seem to have here! A few dealers close to us are always dyno the bike with 10-20hp more than we do. So we took one of our Yamaha R1 and had that done in 5 differnt dealers dynojet and 4 of us showed more or less the exact same hp BUT one showed 15hp more than any of us. And later it was proved he did manipulate the figures BUT the funny thing is that people still go to him and get their bikes tuned since they get a higher Hp! We have runned so manybikes from this tuner in our Dynojet and they always comes out with a LOT less Hp than on his dyno. So it is easy to mainpulate the hp figures in any dyno and I think we all need to remember that we can just use the dynos as a guidline. If you want to see the before and after dyno from parts you need to use the same dyno and condition. So many variables that can make it go up or down. But at least all could agree on showing dynos base on the same correcton factor so at least this is a fair comparison. |

Furthermore, since it's a dynapack it's not going to account for losses attributed to the wheels and tires since it bolts directly to the hubs. The point of a dyno is to show DELTA gains, not compare one to another. I never said reaching a particular number was easily attainable and I have never set unreasonable expectations. I'm sure if you read many of my other posts you'll realize that I'm pretty realistic especially when speaking of dyno numbers. You're comparing apples to oranges. If you want to post dyno runs from when my car was dynoed well over a year ago with a test file (which made great gains I will add), then please post the dyno of the dyno of the MS intake VS the AFE intake that was done on the same day on your own dyno so everyone can see the difference. At least there was a gain with the tune! In terms of marketing, I don't really review my own products. Sal touched on the fact that you do. Our tunes sell themselves and we don't post tons of marketing threads at all. In fact, the BPMSport GB was one of the first threads I've ever posted in the sponsors section. I'm rarely over there. Quote:
Stock cars have their timing targets set at 32 degrees. If you dyno a stock car and it hits 32 degrees, keep running it and if you log the timing you'll see that it will drop down lower because of the rising inlet temps. Then flash a tune in and see what it does. There is only so much than can be achieved out of a heatsoaked car. Quote:
When customers that track their car 15 times a year email me and tell me that post tune they've shaved seconds off of their lap times, that's a REAL world result which holds much more bearing than a piece of paper with numbers on it. I touched on some of these topics here: http://www.m3post.com/forums/showpos...1&postcount=11 I wish this customer would post his dyno but he's probably having too much fun driving his car http://www.m3post.com/forums/showthread.php?t=763362 I've seen a few things from you that I'd like to bring to light but I'm not one to throw rocks in a glass house.

The Church dynapack is very well respected. It was used by European Car in the recent Turner War competition (EAS competed with its upercharged E92M3 and there were two or three other teams running BMWs). A lot of experienced fabricators and tuners were watching and there were no complaints noted about this dyno. Race gas was allowed.

I posted with the simple question of asking: what bolt ons are there for M3? -headers -tune -intake -pulley -exhaust (catless for more power) anything else? |

Ive seen some people using meth kits on the forum but never had the chance to see one in person or dyno one.

There is also the question of whether certain mods add any power. Intakes and cat back exhausts, for example, have shown inconsistent results on dynos.
Meth has the effect of increasing the octane when the meth is flowing. Increasing the octane is proven to add power on these cars. Pencilgeek ran race gas with no tune or other changes years ago and gained significant power just from the car adapting and increasing timing. But meth is usually added with one or two nozzles in the intake and that is not as good for dispersion as individual injectors (though some of us remember back to the days of throttle body injection). Vishnu has a Procede with meth injection available avafor these cars and has posted the back to back dyno results and they were impressive -- the tune alone was worth about 10 rwhp and the meth alone was worth about 10 rwhp and together, the two were worth at least 20 rwhp. E85 is another option that is cheaper than race gas, but not much more widely available. The nearest E85 station for me is about 75 miles, for example. It is also much higher octane, though also less energy so you need about 50% more to make the power, which typically means larger injectors. |

Tom posted my dyno sheet earlier ( post #46 ) in this thread where my car was dynoed with a magnaflow catback, removed second cats, proceed and vishnu meth kit, my car hit the 400 club. Its been rock solid, no issues at all.

Longboarder (edit, meant to say Longbow64) had that kit too and had lots of issues with CELs - if I remember correctly, fuel mixture and o2 sensor faults. After he took the kit off and added our performance software, zero issues to date. Piggybacks are much more prone to these types of issues but certainly do what they advertise in a roundabout type of way. I'm very interested in tuning a meth kit using the stock DME only. I think that the same gains can be achieved. One benefit of the piggybacks however are aftermarket features which usually can not be implemented with the stock DME only.
