Once we resolve the transmission, we already have a larger blower, and have been taking deposits on it as well. In terms of fueling, high 650's tend to be where fuel cut is without needing to go to our stage 3 kit which would be injectors and piggyback to control them. Will have results on that later next month.
650whp is plenty for daily driving on the street, but of course people always want more, which is why we continue to push on how we are.

Is drivetrain loss a true percentage? As power increases does the drivetrain percentage increase? In my head, if it takes 70 hp loss to turn the drivetrain at 500 crank horsepower, yielding 430 whp.... wouldn’t 654 whp mean that you actually have 724 crank horsepower?

That we are. We are working with damn near one of the best transmission companies for JDM vehicles on the market right now. We're not going to skimp out on quality or reputation and we're happy to start on this endeavor. Not only that, this company finally made a huge break through with GTR valve bodies a few months ago. So, with that being said, we're hoping to have some promising results in the next month of R&D.

Interesting read, it's pretty cool to see how far the IS F platform has been pushed in the past few years. It would be cool to see a new valvebody for the guys that want over 650whp reliably with no issues.
