Question: do you have a plot of boost vs. RPM? I see that your torque peak occurs after 7000 rpms (by my guess). Also, do you know what the SAE value was that was used? I wish my torque curve was that smoothe.
I am confident it would already have been at peak in the 5000-5500rpm region(just like the stock tq peak) in better conditions. We only did 3 passes so there wasn't any tunning done on the dyno. Thanks, Chris |

MM, Thanks for updating the dyno comparison thread.
It seems as if something is a little off though. On the TQ graph our curve is at all times above the mazsport kit yet on the WHP graph it never surpasses the mazsport graph(weird because we made 4whp more) and from 6000-7600 it even appears as though teh mazsport was higher than ours when in that range our tq is higher which makes that impossible since higher tq at the same RPM = more hp. Our max tq should also be edited, it was 265+ not 262 as it says in the block next to the graphs. Also, please edit our name to read Esmeril instead of Esmiril. Chris Nice graph, guys. Thanks for finally posting and good luck with the next run |

Wasn't the run at 13psi (not 8, as the dyno comparison chart says)?

I don't know if its the same with every car. I have even seen cars with my own eyes that dyno well just pushing the button for 10sec. For some reason mine is not one of them. My system will flash the ABS light and the car will slow down after 6500rpm like I let off the gas if I just push the button for 10sec and do the run in 4th. If I do it in 3rd it doesn't do anything but the numbers are not as realistic because its suck a high ratio. It might have something to do with the 100mph mark as this is where the issues start happening. Either way pulling the fuse with the car in the off position took care of the problem for the entire dyno session.
Also, I would really like to see a chart of an RX-8 at higher than 366whp with a renesis if you have one available. It sounds awesome and might inspire some faith from the people in the forum :) Thanks, Chris nice to see this stuff up. good job! as to the abs dsc issues, what ecu flash is the car on? seems as we have gone through the flashes that problem went away. beers :beer: |

I am not sure what flash the car is on. Might be an M or something of the sort. After I went standalone I stopped caring about flashes. The fuse solved the problem though.

for the long term life of the car keeping up with the flashes is a very good thing. you are about about 5 or 6 behind. and a lot of oil of the omp. the last on i think is w.

Oh wow. I'll drop by the dealer then. Its funny, my car is still under all warranty except power train...the techs love it every time I bring it in.
Thanks, Chris beers :beer: |
I applied the new dyno (in RPM) to the comparo.
It didn't really improve anything since the actual run was shorter than I calculated. The Esmeril has a torque bump early on that is attributable to the WG opening, but after that is is virtually identical to the MazSport. I've included a pic of the raw plots against each other below if there is any question. http://www.mazdamaniac.com/images/misc/es_vs_ms.jpg |

I've included a pic of the raw plots against each other below if there is any question. http://www.mazdamaniac.com/images/misc/es_vs_ms.jpg The max number at 7500 is 366 however and not 362 so at that point it should look higher or at least the same but not under as it did from last night. In the range where that "bump"(not from the wastegate as that opens from about 4000rpm, it only looks like a bump because it went extremely rich shortly after but would other wise be a consistent part of the tq curve) keeps the tq curve above the mazsport curve it should reflect as higher in hp in this range like in the pic you posted above, but in the comparison thread it didn't look like this unless I am confusing some colors. Our TQ number, boost and name does still need to be changed. The rest is just for visualizing, so I understand. Thanks for the help. Chris |
MM, I just looked in the comparison thread and it looks vey good!
Our TQ# is still 262 when it was actually 265 but I don't think its that important, we will post another dyno soon anyways ;). Thanks for the help. Chris |
Sorry. Typo. I'll fix it.
When you have a scaled dyno sheet like that, the difference in 3 ft/lbs will not be visible in the curve. As you can see in the raw version I posted above, your curve lays almost exactly over the MS curve. |

MM,
I just noticed that the price you are displaying in the comparison thread for our kit now reads $7170, this is not correct. The kit price is $6895 including the Int-X. I assume you added the ignition upgrade to that but that is not the correct number to be there....the kit price in the only thing that should be there simply because all other kits tested are not reflecting the other modifications people had made to their cars. The mazsport dyno run was done with the mazsport ignition solution installed and the one for the MM/BHR dyno run was Mysql's car which had the mazsport ignition solution installed as well. There might be more that had other "non-kit" additions too and we cant determine that so they should be left out. The prices displayed in the comparison thread for the other kits are the prices that the manufacturers are selling the kit for. None of these are taking into account other stuff such as different exhausts, gages, sparkplug wires, boost controllers, or anything else of the sort, therefore our ignition kit should not be added to the total kit cost as if that was the price of the kit. This is in effect changing our kit price from what we set it at and only we are allowed do such a thing. I want to clarify that we are not trying to hide anything here and that is the reason we clearly stated that we had used the ignition upgrade first thing when I created this dyno thread, we just want to keep a fair/level playing field by comparing apples to apples. Please update this to the correct price of $6895 Thanks, Chris |
Great job Esmeril! Dynos and videos work absolute wonders in changing opinions... glad to see you guys come right back with some solid data and continue pushing the system. The Rx8 needs all the aftermarket support it can get, and these numbers look solid.

Nice numbers Chris,
Any ethanol in the future? :eyetwitch |

Just to clarify, I lost 50 whp when I had that ignition on my car, so it's one dyno sheet I don't intend to post. |

Your dyno is listed in the thread. Perhaps MM was updating it? It shows 366/265 $7170

BTW congrats!
