Yeah I have.....and I will once I start running a bigger shot.....but my 318 likes the 110 stuff when I am running NA because I can run 34* total timing when i am at the track. I only fill up with 110 when I know I am gonna be going to the track and spraying the car.....any other time I run pump 93 and keep the timing to 30* total. So it's not like I run the 110 all the time so it's not that expensive....and honestly this is the first time I have run the 110 in the car all my previous passes have been made with pump 93 in the tank and the nitrous kit using pump 93 as well.......I just filled her up with 110 the other day to see what it would do and it ran better with the 110 @ 30* of timing and when I bumped it to 32* it ran even better on the street......and the nitrous kit should like the 110 even better but I'll know that for sure here in a week or so when I can get back out to the track to test it out.
