For new build will be 8000rpm. Current motor and setup is 7500rpm. After watching a few vids, think i'm happy with my decision. Car will be dam fun to drive on the street, which is usually what it gets used for.
This basically is what it could look like, minus a few HP lol. These are the shorter ratio gears with big power. He is shifting at like 8200rpm though. Watch from 2:50
Has anyone here installed the Raptor headers that can give me some info? Has it affected fuel efficiency? Obviously its all about how you drive but I'm just wondering if the reduced back pressure and advanced timing (with a tune) also makes a noticeable difference to fuel efficiency? I have an XRT base tune that I got when the car was stock (just K&N air filter) and Edward had to pull a lot of timing to prevent the engine from knocking. It seems counterproductive but it actually made the car run much better because its not always knocking and drastically pulling timing. He also improved throttle and transmission response so the car drives much better than it did with the stock tune. The downside to this though is that the fuel efficiency is marginally worse than it was in stock form and I believe this is just down to the fact that the timing is retarded slightly which results in slightly less effective use of combustion pressure (peak pressure occurs slightly after top dead centre). I watched Turbo Yoda's video on YouTube where he talked about the EZ30 and he said that the stock headers cause the car to knock badly and that by installing aftermarket headers it fixes the knocking so I inferred from that that we could advance the timing beyond stock timing once headers are installed which would improve power and fuel efficiency.
Any thoughts anyone?

I pulled apart the rear floor to try and find a tow bar wiring harness but JDM Legacys dont have them so looks like i will have to splice into the factory wiring(which i hate doing even though i do it work all time) Scored me a Tow Bar for my BP5 from Subwrecks so going to try and fit it soon
