But much respect to you for the great dyno numbers.
ty, i just recorded my dyno pull on my bf gauge and watched it. Hits 1.5 bar quickly and has a quick dip in boost but then holds pretty good to redline.

I have many friends that have done this so I decided to try it this time.
J/K... great numbers.

Curious? If the published flywheel numbers "are not actually measured." How do they obtain these figures? I am just curious.

We should sue for false advertisement

- LS1 TA/Z28 in the early 2000's. They were listed at 305 or 315whp, but then dyno'd about as much as they were published to have at the flywheel. GM did this, because they couldn't feasibly advertise their TA/Z28s as having as much power as the Vette. That would have been bad for sales on the Vette.
- SRT-4s - When these came out, they were listed at 230hp or so? Well, when people started dyno'ing them, they were showing that much power AT THE WHEELS. Why did Dodge advertise the wheel HP instead of an estimated crank HP? I have no idea, and I don't know if it is public knowledge, but I know they responded to the questions by "raising" the published HP the next year even though power output wasn't changed.
- RX8 - Whoops, published 250HP, but dyno'd nowhere near what you would expect from a car with 250 crank HP. In response, Mazda lowered the published claim to 237HP and gave refunds of some sort to every RX8 owner
- '01 Cobra? - can't remember if it was 99, 00, or 01, but one of those Cobras was just like the RX-8. Ford claimed 305HP or something, but they were dyno'ing no higher than the same year's GTs. Cobra owners raged against the machine and ended up getting some sort of reparation from Ford.
I couldn't tell you why Mitsu rated the 05s at 276/286 (too low) or the 06s at 286/29X (way too low), but I CAN tell you that the numbers are underrated.

There has to be some sort of measurement, that means they could post the numbers at 350 hp, or anything above or below 286. They have to have some sort of baseline measurement, not just pull some number out of their ***.
