Let's not forget to throw Ray in there.

 

I figured that out before you did i think .....

 

Dam, he was so quiet I forgot the leader of BHR sorry .

 

Nice # Phil and congrats on it making a pull using the full rpm band!
How much air are you pushing at what psi?

 

Great job guys and you too Ray! Now me next, me next!

Saving my pennies for next summer install.

Thanks for working out all the kinks Phil and Dondo!

Cant wait to see/hear it next month Phil.

 

As usual I don't have the answer but I am sure that Todd or Erick will know. Erick came to Vegas and ran off with my car took it to Ray, Todd and Tony . They keep gaining on my magic number.

How is your turbo doing?

 

Todd knows the MAF numbers. I remember something in the 380+ range.

 

Your point is moot.
Here's a few I like:

2) Cynic
3) Misanthropist

 

Congrats old man! Nice dyno.
You can get it to 300 rwhp if you want it bad enough. Pay attention to heat soak, air restrictions and your exhaust.
Will the trans be ok at that level? Probably....?

 

Coo, thanks!

 

Erick is just a plain 'ol thief. Turbo is doing fine, just need more fuel, dont have big enough inj.

Thank you sur!

 

again, if you want to be hung up on numbers then let it be the MAF voltage rather than whatever magical number you wish the MAF voltage to display

 

So many of these threads end with someone trying to pick a fight...Too bad I was hoping to get some good input. I guess I'll talk to all of you at Seven Stock.

 

The primary issue with using MAF numbers as a pure figure of measurement is every custom tuned RX8 has the MAF calibration adjusted for tuning purposes.

For example, in some early troubleshooting with Phil's car, it was necessary to totally jack the MAF calibration to see if I could squeeze any additional fuel from the injectors. The PCM thought it was seeing 400 g/s of air which was FAR from the actual value.

In this case, the WHP output is the only non-adjusted figure that can be relied upon. On average, I've seen information suggesting that the RENESIS produces .9 whp per gram of air per second. That puts Phil around the 292 g/s range (in theory).

Mass airflow does have plenty of applications by which it serves as the superior measurement of power generation (the whole airflow vs. boost argument) but we don't gain much additional knowledge of the car's performance beyond what the dyno graph shows.

 

Circular reasoning - Wikipedia, the free encyclopedia

 

just out of curiosity, do you honestly think that my unported NA engine makes 234 rwp? I'd call BS on this too because I'm not stating anything in this thread that doesn't also apply to my RX8 as well as this or any other one. A more realistic number is under 0.85 and probably closer to 0.80. Note that I don't post or otherwise ballyhoo any of my past or present dyno graphs since about 3 or 4 years ago ....

you also have to remember that driving a supercharger requires a significant amount of HP, especially at high rpm. In this case the actual rear wheel output per g/s of mass air flow will be even less ...

my intention is not to fight, but sometimes this is necessary to cut through the bull, fantasy, or lack of understanding

 

No, it is obvious that you do look for any confrontation that is available and while I have no problem with you calling me a lier I do have a problem with you calling my friends liars. Every thing that was done to my car is out in the open and all engine mods were done by highly respected members of this forum.

Why don't you just start your own thread as I am sure that it would be successful and that you would have a thousand followers and maybe some one else to call out. The only trouble is that you would have to acquire an original thought.

 

This was a nice laid back informative thread until someone had to show up and stir the pot for no reason. Yep Team is a d-bag and I approve this message.

 

Right, because we can't have someone on the interwebz be wrong can we?

Anyone who has experience with tuning or dynometers knows full well that calibration can impact your readings even with SAE correction. That is why it is important to use the same dyno as much as possible for any power gain measurements because otherwise your results are skewed.

As a noted above, Phil's reported MAF readings are most likely not correct. I can't say with any certainty because we don't have any independent method to review them. We can deduce the approximate value but that is all it is. Notice I was careful to mention "(in theory)" since we are well aware of the variables and don't tout ourselves as the final authority on this matter. A characteristic I see that isn't shared.

We posted the dyno because we wanted to show the work that has been done on Phil's car and because we thought the community would be interested. All we are about, in the end, is the satisfaction of the customer.

 

great #s Phil !!! would love to be there myself and still have a ways to go... but OMW.

In regards to all the noise that I skimmed over (mostly due to the fact that a certain individual is on my ignore list and I can now choose if I want to be spun up rather that have it thrown in my face) I need to go look up Pedantic. I l-o-v-e new words

 

And we are interested, just FYI.

You will post new dyno when more tuning have been done, right?

 

Phil's NA HP was likely somewhere between 130 and 150 whp.... Seems pretty damned tuned to me.

 

^My bad. I saw 300whp earlier, mistook it for a goal, but I see now that it was just a encouragement from a forum member.

 

I think we all have a goal 300+ whp

 

Without getting into specifics I do believe there is still power on the table. We were running into a situation where safety was beginning to become an issue. While we all want to see big numbers, we want Phil to drive his car.

I'm sure we will see some future updates for Phil's RX8.
