Tort was a "balls to the wall" driver. I bet he rev matched every shift and his syncros never saw the work
. 375+ whp with an AWD chassis should put you in the 11s. Too many do it for it not to be a given. 128+ mph with an AWD is DEFINATELY over 500whp. GORBS88 has a good thing going.
My h1c really loves pure water injection. Adding meth doesn't really do too much for it. Any more than running much lower octane isopropynol. The cool charge was a plus to my gut (insurance), but not to my loggings. It likes boost and is efficient already. So any knock retardant will help. Pure water is easier to come by and no real difference was noticed in this setup.
The hx40 is different, but the same engineering goes into it: diesel high load engine with surge issues, lots of flow neccesary to cap emmisions, and BIG boost to allow a smaller engine / lower rpms to be used for maintaining some symblance of fuel economy.
