so lets take some things into consideration. i think first need a rough idea of horsepower to calc out fuel needed. then assuming its not making 5300hp like some pro mods you could calc out lambda to see if possible. reason why i say a pro mod, as mentioned at one time i talked to moran when i purchased some injectors from him for my car (which were too big - my fault) he told me his ride was 2.9-3.2 afr meth. now really need to work in lambda for calculations because it doesn't matter what fuel it is, the lambda value is the same regardless of fuel. if lambda for the mixture is greater then the 2.9 afr meth then i would say yes its possible in an EFI situation because efi has precise control throughout the range. also, i think most pro mods all run 8 egts as its giving quicker readings then the egts. some run both. 8egts with controller is big bucks, especially to read that low.
for DISCUSSION purposes only, safe on meth is 4.0 or .63 lambda and lets say (idk... ) safe for nitro is 1.0 afr nitro scale or .59 lambda.
for 30% nitro 70% (.7) meth, 30%(.3) nitro
(.7 x .63 safe meth) + ( .3 x .59 safe nitro) = .68 or 3.97 afr meth.
assuming a sensor can read that low, then its possible at that hp level. we could create a scale for meth using max meth afr of 3.0 for 5k hp and use .63 for 1300 hp. then lets say do the same for nitro based on 10k hp and
afr ratio to say same 1300 hp and what afr ration nitro it is. then just put those into lambda, do calcs, then convert back to meth scale if need be.
the ntk sensor for meth will read down to 2.66 meth which is .42 lambda. its just a matter of finding a controller that will read that low. moran wants 600 bucks for one sensor. assuming .68 is ok, thats 10.0 on gas and you cant run a standard bosch sensor (for long). so you need a ntk sensor. if you did all 8 thats 5k plus the controllers.. prob looking at 8-10k min.
as a swag, will it work or read id say yes to about 4k hp lets say if staying with 30% nitro. but as Bruce alluded too in his post.. it would be so saturated it would be killed in no time. can it read, yes, is it possible i doubt it as the sensor would get killed. as mentioned on EFI setup they can control precise fuel throughout and prob not kill the sensor. on meth, isnt the tuning window about 2k hp range? if so, then super fat from idle to the target rpm tuning range window.
