remind me to never try to think at work . i fixed my post! you will end up being about 31-32 nozzles. but depending on pump flow you will raise the psi and the fuel curve wont drop as much as ya think . keep riching on the methanol till ya loose mph and we can figure out what your limit is then we can use the pill and nozzles area to figure out your psi as long as pump is ok .does it still have the flow tag on it (rated at 4000 pump speed). is your belt drive a 2-1?

I only have one richer pill which is a 70. I will try that to see if it drops speed. I do have 31 nozzles. Is the barrel valve likely to be on the rich side as it is now? Pump drive is 2:1, but i'm not sure about the tag, I'll have to check. What kind of EGT on E85?
Thanks again for the info,
Chris

egt is relative to your tune . not a ideal number like O2 .
you tell me where it drops of mph rich on methanol and we tune it to that egt on e-85 and then can safely lean on it till mph stops picking up . your b/v adjustment will be 2 flats richer just when it will take a throttle snap. measure the turn buckle lenth and note it to the tune. then see if it comes on converter with brake /2 step what ever . after ya get the mph top out we can do timing loops then lash loops . then see if the pill can get even more . i have found 3 tenths over a baseline dyno tune this way . your egt should track fast rise with a decreasing rate of climb and stagnate about 1100ft if this is not the case we need to plot a h/s bleed curve as your pump vs load is to much up stairs ...mostly high rph smaller engines though .

We'll do Adam.
Thanks again.

What kinda lambda readings do you tune for with injection? I'm guessing that idle would be fatter than a carb, but what about WOT?

i never let my injection idle with out pulling on the leanout valves to get the egt up .it only needs to be pig rich to take the throttle snap on the line .. the lambda is not so much a moving target as egt is but it is still relitive to your o2 and placement i was going for .82 on my brothers carb/turbo car and we swapped in a new o2 and it went to .85 but went faster so the air got alittle better and i expected it to move but not that much....... so try it rich first at .79 and lean on it till it slows then hit the middle . and lock it into your memoery.

OUCH! It always hurts to see a nice car like that get hurt. Was the driver OK? That is a great looking car you have. I am very impressed that is runs that well on E85. I guess I underestimate its potential.

I just saw the video. All I can say is HOLY S***T! I hate to see things like that, but glad he came out o.k. We all hope that never happens to us or fellow racers, but it's always in the back of your mind. :ol

My head hurts after reading some of these posts about tuning but then the video really hits home everyone should take the time and check over all of your safety equipment wile we are not racing over the winter so when we go back at it we will all be safe for next season, happy tuning/racing to all
