Strm Trpr Posted November 5, 2015 Report Posted November 5, 2015 i had a similar problem and i had about 130 pis comp and was running 93 octane and it ended up being too high of fuel causing it to bog at low end , mid range and a weaker pwr band so i just got some 89 and it helped a lot that might be ur problem try 91 If the motor picked up after reducing octane, then I'd advance the timing rather than reduce the octane. 1 Quote
Darkblade Posted November 5, 2015 Report Posted November 5, 2015 if you`d have said "my 130 comp motor ran better on a lesser octane fuel than 100+" there would be some merit to that. using a too high of an octane fuel in a low comp motor it will struggle to burn it efficiently , but dropping from 94 octane to 89 fixed the low end bog...no well the fact is that all i did was change the fuel from 93 to 89 and it fixed the problem so dont say that it wouldnt do it because it did 1 Quote
Darkblade Posted November 5, 2015 Report Posted November 5, 2015 If the motor picked up after reducing octane, then I'd advance the timing rather than reduce the octane. i would have advanced the timing but pretty soon im getting new domes for 155 comp and all i have available is 93 so i cant run both domes and timing Quote
Deadbeat Posted November 5, 2015 Report Posted November 5, 2015 well the fact is that all i did was change the fuel from 93 to 89 and it fixed the problem so dont say that it wouldnt do it because it did way to go attaboy? its still a retarded fix Quote
