Driven Innovation Intake w\75mm TB
1mm Oversized TurboTrix Cylinder Head
2.0 liter TurboTrix Built
HKS DLII Ignition

With a 1.8 60ft it ended up with a 10.8 @ 135!!

Thanks guys! 40 plus PSI Next time.. but I have to wait till a track rental.. they are a little more "friendly" about not having all the proper safety equipment. If low boost/pump gas is getting me kicked out.. Not sure what 10+ PSI and a **** load more timing is gonna do..
This was in Dirty Jersey, not NED lol

10.8 on pump gas with a 1.8 60 ft? Nice job man that is awesome.
Hell if you cut a 1.5 60 ft you'd probably run a 10.2 or so. Dave Buschur had to step up to a slightly bigger turbo than a 35R if I recall to get into the 9's on pump. So basically it seems your making the same power as Dave's RS on pump?

It depends on a lot of factors. Larger turbos are more efficient at 30 psi than smaller turbos, therefore the charge temps are lower. Also, larger turbos normally mean larger headers and turbine housings, this means less back pressure, which also can help fight detonation. Plus many other factors. Basically there is no rule of thumb that says X amount of boost pressure for Y amount of octane. Every car/setup is different.
