C16 for the street or MS 109

[D-MANN]

Does anyone roll around on the street with VP leaded C16 fuel? Have any idea how long the O2's will last?Any other issues a guy would have with running leaded fuel?Would I be better off getting a tune with VP unleaded MS109 instead?I plan on getting a tune for 94 pump with 17 psi and a race tune with 21 psi.Just unsure on what fuel.Would it be ok to mix MS 109 with Torco to get closer to the motor octane of leaded?VP C16 motor octane 117 and MS109 is 101.

I would use Sunoco 104.. It's a true 104, and you won't have to mix anything..

I wish I could give it a try but it is unavailable where I live.

Oh damn that sucks.. hmmm. I would say 101octane on 21psi won't be to bad.. You can't run 22 degrees of timing though, so slightly less timing and more boost..

ok that might be the route I will take.So 17 psi on 94,21 psi on MS 109 with less timing and a race tune on 21 psi with C16.The track isnt to far from me so should be ok driving there on C16.Im curious though on what ill affects leaded has on our cars.Anyone?

You should try that Shell urt fuel, it's supposed to be equivalent to c16 but makes more power and without the lead.

Problem is that Shell URT advanced is gone with no ETA of coming back.. You can use the Shell URT regular or whatever and that has a pretty high octane rating.

Just run meth and you can run more boost on the street. Cheapest way to get more power over pump gas up here in the sticks.
