New tune for Higher Octane?
Currently I run a Troyer Tune for 93 octane... race season is starting up and I'd like to up it a little.
My thoughts were this... if 87 octane can get "X" ammount of HP.... 93 octane can get "X+3" ammount of HP.. then would 95-96 Octane get "X+5" HP #'s.. strictly for track use? Hp+3 and+5 are just a representive.. not meaning anything actually.
I figure if I mix a small ammount of toluene into the gas and have a RACE only tune for 95-06 octane.. I could effectively up the HP output some and essentially lower my times... N/A 3v-RegularCab.. many bolt ons..ect.
Would I need Plasma ignition boosters to maximize the 96 octane burn?
I'm gonna call troyer Perf soon and talk to mike or someone about it since Mike does the tuning on my truck... just thought I'd post about it first.
Is this logical thinking? or am I going too far out on a limb here.
Any Thoughts?
Thanks,
Keith Hendrix

Hi Keith,
The 5.4 3V has a compression ratio of 9.8:1, so for a modern engine it is a "relatively" high compression motor, thus we can get some more power out of it by using and tuning for, a higher octane than 93.
Now I am NOT a fan of just dumping toluene into the tank to up octane, as you have no idea what that does to the overall fuel formulation - yes, it IS an octane boosting ingredient, the oil companies pump premium fuels are already 40%-50% toluene by volume to begin with!! But you don't know how much toluene gets you how much more octane...........
What I recommend is to use a properly formulated fuel, and that is actually very easy to do anywhere - Torco Fuels unleaded "Accelerator" is what I recommend. It is a concentrated race fuel, and it doesn't take much to add to 93 pump premium to get you up to 96+ octane. A lot of us use it.
And then decide on how much octane you want to run, and have us do a tune for that level of octane to get maximum power - what would be really nice is to have it here on the dyno and have us tune it for every last horsepower while we monitor exhaust valve temperatures & all our other normal parameters, etc., so that you can get maximum safe & sustainable power from it - that would be the ultimate - but we can also do this by mail order with proper datalogging.
Give me a call to go over this with you so you'll have a good grip on this and can thus decide what you really want to do, OK?
Good post, & talk to you soon!
