I can get that at the pump - but I usually mix 110 leaded with my 92 octane premium.

We run NTK sensors with C-23 race fuel and obviously have a two step. The current sensors are on their second season. They are about $180 a pop Monte

I take two extra (used) plugs and the socket wrench in the car with me when i make a pass and need to check plugs.. click it off after the stripe.. coast off the track pop the hood. and pull a plug from #1 and #7. replace with the used plugs. drive back to pits and read the plugs in your hand. tune accordingly. then install two fresh plugs in 1 and 7 make a new pass..and repeat. a box of 8 plugs will get you four passes to tune on..instead of using 24 new plugs in every hole..for the same 4 passes.. when you get it where you think its working...then i pull all 8 at the end of the track to make sure all 8 are happy... why do people make things so complicated... i read somewhere.?you can soak the 02 sensors to make them work again..cant remember what the stuff is called that you soak it in.... ive never done it.. 365" Iron J heads,,3480lbs best 1.39 60ft on SS springs.10.54,124 mph ...6.67 1/8th et.average 60fts 1.46 w/ small cam &.063 no2 pill tagged & insured [image][/image]

For carb tuning I always liked the lm1 with rpm converter, and added a narrowband sensor/ map sensor in the aux inputs. This gives you load, rpm, actual a/f ratio, and happiness a/f ratio. Very usefull info... "use it 'till it breaks, replace as needed"

The narrowband sensor needs to be used as a means of seeing if the ratio that your wide band is reading is what the engine is happy with. You need to ignore the narrowband output VALUE, and just pay attention to the AMPLITUDE of the voltage signal. A jagged voltage line tells you the engine isn't digging the current a/f ratio. Example: your engine is running at a 12:1 ratio. You look at the data log and at 12:1 the narrowband voltage output is not smooth. You can go richer or leaner and see if the amplitude gets lower. If it gets higher(more squiggles) you went the wrong way. Alot of people have dismissed narrowbands. I'm not one of them. "use it 'till it breaks, replace as needed"

Ok, got a chance to fire it up today in the garage only. Per the digital wide band gauge, idle A/F was around 11.6. Turned in the idle mixture screws a tad and idle A/F went to 12.2. Held the throttle at 2500rpm and the mixture went very lean at about 15:1. - no boost, 10" HG, and on the primary's only. Got some smaller hi speed air bleeds on order. Tomorrow I will run some WOT tests under boost. Fastest 300

Crizila OP master Joined: Oct 2003 Posts: 7,506 Az	Finally got a chance to run a few WOT tests today and I was getting wide band readings in the 10.5 to 10.7 range @ 6200 and 15 lbs boost. Keep in mind I am testing with a full exhaust and 5000 feet above sea level. Still way fat - I would think? I will try going back to original jetting ( as I got the carb from Pro Systems ) and see if that will lean it up a bit. Pretty sure that is where my short plug longevity problem is coming from also. - - lead fouled. Fastest 300
