Just been thinking of ways to find all the power in the car so here me out here....

1-put in 110 unleaded gas for the dyno tune....my under standing is you will hit a spot with timing that you will not make any more power..is this true and will haveing the 110 in there change this in any way other then safty(eng)

2-same thing with leaning the car out 13.4 area will the 110 mask this in any way.....

just trying to find ways to get that extra 10-15 extra rwhp out of the car....

or is there other things i should be looking at here to find more power on the dyno...


thx

 

If you find 110 octane unleaded let me know.... the best I can find from Sunoco Racing or VP fuels is about 103/104. VP C10 unleaded is only 100-octane (R+M)/2. When you look at "octane", look at the "motor octane" number, not the research or (R+M)/2 number. "Motor" octane is measured under conditions more like max throttle operation.

Tune it first for the fuel you plan to drive with on the street. Using 100 octane (or 110 octane if it exists) may give you a different "sweet spot" than a real world fuel, and you could end up with the wrong tune for normal pump gas - e.g. detonation.

After finding the best tune on real pump gas, increase the octane level to what you would expect to use at the track, and see if you can pick up any HP with different advance or A/F ratio. I found a big difference between 93 and 94 octane on my 10.8:1 engine. But going up to 100 octane unleaded did not allow any gains through various timing and A/F combos.

You may find you want to run a different tune on the street than you run on the track.
