I am happy with that for a street car. The tuner did make a comment though... "tuned for E, but you won't really gain the benefits of the E until E60. 93 and meth is more than enough at this point" Regardless.. I am running E in the car if its available in FL where I am moving too.  |
The tuner is probably correct. Pump and Meth is similar octane as E40-50. E60-80 would still produce lower EGT's due to reduced cylinder temps on combustion and make more power. On a forged, lower compression setup like yours, you can run it either way. There is enough margin for error to survive higher cylinder temps and any potential cylinder distribution inconsistency from the meth system. There is just no way a nozzle injecting fluid ahead of the throttle body can properly atomize and evenly distribute to all cylinders like 8 high pressure injectors fogging directly into the chamber. That doesn't mean it don't work because it still does...just not ideal on stock piston LT1's.
On a tight ring gap engine with mediocre pistons and high compression such as the stock LT1, we have to keep the cylinder temps as low as possible and need fuel evenly distributed to all cylinders.
But you jumped that hurdle right from the start by upgrading the internals and lowering compression. So you are good to go. Should be a fun setup!!
