I am heading down to firebird tomorrow night.
Doesn't look like they have any big events planned this weekend so hopefully I get get some runs in.
Anyone else?

I got my MT Sportsman front tires so I can cruise down there on the slicks and skinnies. 10 gallons of VP 109 in the tank. I am ready to roll.

I was doing some tuning today so I burned some. Tuning on pump gas then running 100% race gas can cause some issues as the stoich ratings between race and pump fuel varies. VP 109 has a stoich of 13.65 and pump gas is 14.64. I have no idea what the winter oxygenated gas stoich rating is, but it burns leaner than the summer gas. I would guess around 14.2 based on my data logs and research.

My A/F was 12.0-12.3 on the race gas compared to 11.6-11.8 on winter gas with a can of torco.Sold

My M/Ts are a couple years old so I am sure they are pretty hard but there is still a lot of tread left on them so I am gonna use them until they wear down. Originally Posted by Wharf Rat

Would go but I'm not too happy with Firebird at the moment. I want it to be a night where I'm sure there won't be some BS.
