not a lot...i think Nos phamplet says up to 100hp NOS on 93 octane...then from there they suggest the better gas...

you would still need to back out about 4 degrees of timing to be safe at 100 shot with 93 octane


it would also depend where your static compression is...example: 7:1 can probaly handle a little more than a 10:1 static compression motor....and both engines are Pump gas...one is just on the low end while the other is on the higher end.
