20 psi on E67. Or is there much of a difference in hp numbers between E67 & E85?

Ill let the tuner chime in, but the 355 was a small typo. I believe it was 335whp, still rather impressive . Previously the pump gas tune netted around 320whp, but the addition of the PTUNING header bumped up the efficiency and even allowed for more timing. As far as correction factors, PTUNING will never implement a correction factor.

Good work guys. Advancing the platform is really coming along fast. I think daily 400whp is easily sustainable for the long haul (5+ years) IMO.

I don't suppose you have an actual log of boost pressure?
These dyno plots with the "double hump" effect are interesting. At first glance it looks like a really laggy turbo but you are still making quite a bit more torque than stock even at lower RPMs. Last edited by xwd; 02-23-2014 at 07:00 PM. |

in any case it's damn impressive, and that's really all that matters. |

Sorry guys, I finally got a chance to get to computer. I guess with so many numbers included in my original post, I fat-finger typed the pump gas whp. I guess you can say the pump gas numbers were sort of the red headed stepchild in my post. I was more focused on the E67 numbers.
I'll go through and answer some of the questions that were asked, but before that I wanted to go over dyno differences. I know the, "our Dyno Dynamics Dyno reads 10-12 percent lower than a Dynojet" comment gets thrown around a lot and people can take it for what it's worth, but I'll give you some things to consider. You can draw your own conclusions. We'll use three examples here, all from well known reputable tuner shops. The examples here all use our very efficient low-mount S2000 turbo system running a GT3076R and GTX3076R turbos. This AP2 S2000 runs our GT3076R turbo. During tuning, my best dyno pull on our Dyno Dynamics dyno was around 431whp at 13.5psi. The customer randomly showed up to a local Inline Pro dyno day a few months later and made 475whp on their Dynojet dyno, even with improperly gapped plugs that he just dropped in at the last minute. Here is a dynograph of a GTX3076R that we tuned running Q16 and 22.5psi. Here is a dynograph and video of a GTX3076R tuned on E85 by Full Blown running 18-19psi. [ame="http://www.youtube.com/watch?feature=player_embedded&v=cdQ3_lidK64"]s2000 E85 570whp tune Fullblown Motorsports - YouTube[/ame] Here is a video of a GTX3076R running 93 pump and direct port WMI tuned by Evans Tuning on their Dynopack hub dyno. [ame="http://www.youtube.com/watch?feature=player_embedded&v=7OUIIwDQLjI"]Honda S2000 w/ PTuning Kit - 580whp / 445tq - Hondata FlashPro - Dyno Video - YouTube[/ame] So as you can see, there is a reason why it's an accepted industry fact that Dyno Dynamics dynos read lower. Sure there may be a few shops out there that use false correction factors on Mustang, DD, Maha, Dynocomp, and Dynopack dynos to sell product. We always choose not too.

At 400whp and 300wtq, our Exedy Stage 1 never skipped a beat, so we're still not sure what it's final holding capability are. However, we didn't want to waste time with the clutch being a potential issue so we installed the Exedy twin-plate clutch.

The funny thing is though that some people will get so fixated on a boost curve rather than just looking at the torque curve, which is all that really matters in the end. - Toan |

I think it's safe to say that Exedy severely underrates their clutches' holding capacity at this point...lol
