We do not have a plot of boost vs rpm. Full boost of 13psi was attained way before tq got up there but because of the supper low AFR's(low 9's) in the before and after 5000rpm range, due to the lack of ventilation in the dyno cell, the TQ was disturbed in that region and had to slowly creep back up.

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

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

Nice graph, guys. Thanks for finally posting and good luck with the next run

Yep...I missed that one....haha, thanks for catching that. It was kinda late when MM updated the thread so its understandable .

Thanks,

hey 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.

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,

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.

That is fine, I know this is just with the purpose of having a rough comparison and that it will never be the same as taking all kits to one dyno and doing one after the other, just though I'd point these things out.
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.

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.

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.

Yeah I saw that. Its fine, I'm happy. We will hopefully follow up soon with another dyno anyways. Thanks for the help.

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.

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.

..I dunno...perhaps...

Chris

ChrisRX8PR

iTrader: (1)

Oh ok, I take that back then. Still, the point of my post was to point out that other kits in the same graph are known to have been run with added cost upgrades and only the kit alone prices are shown in the box, our kit is running 91 pump fuel and it is running exactly what comes out of the box and nothing more. The only addition is the ignition upgrade because it is not possible to post a good dyno without it and we wanted to post a dyno that showed the capabilities of the kit.

****Edit: Computer problems caused me to see old data from the comparison thread so I removed this text****

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

BTW congrats!

ChrisRX8PR

iTrader: (1)

It is listed but it says 302hp and 227tq as of 8/28/08 at 11:00pm. If indeed MM is updating the thread then an apology is due on my part.

BTW, thanks for the props

WTF???? I had not logged on this computer since last night. Apparently it was just recalling the pic from the cookies or something but it was coming up as what was there last time. I kept refreshing and it didn't do a thing until I hit shift+refresh and then it updated everything. Thanks pdxhak....And of course my sincere apologies MM.

Best regards,
