Should i pull more timing?
23 degrees on top with a 230 shot from 3,000 on a window switch full wieght 2500hd 6.0 12.38 @ 111mph (stock stall) pulled hard the whole track, no knock detected


I run 93 pump gas always, if i add 110 or c-16 to my tank will it affect my factroy o2 sensors? Would it be worth the cost over the benifit?

 

Run a stand alone fuel cell with c16. Yes you need to pull more timing.. Do alot of reading on yellowbullet.com in the nitrous section on reading plugs. What plugs are your running?

 

Really work on reading the plugs. You would be surprised how often nitrous builds will go faster on a little less timing.

 

^^^ What he said, We have seen several instances that you can speed up even with lest timing. Also I would not really recommend running c16 or any leaded gas if you are running factory O2 Sensors. The gas will eventually damage the sensors. Like Dirt track racer said most people use a stand alone with higher octane gas. That way you only spray the high octane when you are spraying and it will not affect your O2 sensors near as much.

or a leaner tune up. most jet charts are on the rich side (for a good reason).

 

Im running tr7 plugs i have a set of b8es plugs but i dont use them till track day. And im going to pull my timing down 2 more degrees to see how it does. Keeping it on 93 unless i get backed into a hp corner. I also droped 300lbs of curb weight from the day i was on the track
Hunting down that 11.99 pass on a stock converter lol

 

Why a tr7? Why not a br7ef?
