Agree, you have external fuel regulator?? Or stock?
My car has 360rwhp with problem in old dyno. I think in modern dyno I get 15 more same boost (15). But right now I use my car daily at 10psi. |

Stock regulator with a DW300 pump and some internals mods .
Me too, but Rocky told me it's not good to use that for the 400rwhp. An external one is necessary. When using the factory forces the pump and the injectors to the maximum and that is not good. Fuel pressure is important to be the same all time. I use line 6 from the pump to the injectors and I will use the fuel factory line for return with external aeromotive regulator 13129 for the modification. We will continue to try new changes. |

Mine runs around that 400whp mark currently and I couldn't agree more ... I run 30%Ethanol and I think it's a great fuel . Good mileage , great octane , great cooling properties and 100% reliable (as long as I can get E85 to make it up with) . A better option than injecting meth IMO.
I would add that 400 is about the limit of the Renesis exhaust ports no matter what octane fuel you run ...go much higher and you will become well known to your engine builder . |

And mine 60psi. But it is not the same a stock regulator of few pounds that one bigger with greater handling of pounds of pressure. I will make the change for an external one and try. External regulator closer to the fuel rail has to make some changes. We will continue to improve and research with the results.

RX8 R3 11 psi on the way to the gym

Your AFR's are on point.
|
Almost always at 10.9, 11.0 when it activates methanol. That day was the weather a little colder by the rain that had fallen. But 11.5 is good too.
|
I was being sarcastic, that is rich at idle.
|
That is the key for engine life with high compression.No matter that you miss some rwhp. Talking rwhp how much do you have? You talk like you have 400 rwhp and only have 300 ������lol. When you get more that I have your sarcasm maybe is important to see.

Can not stand the power. Thank God I have another one. I think I need one in aluminum soon.

Boost wont do that . Must have been a backfire into the intake ?
|
:lol: Definitely backfire. And I would love to hear about how super rich AFR's at idle keep the engine safe.

Apparently intake already hurt. When entering 12psi was crack. Tomorrow I install the other I have.
