04SSR1,my ssr is an 2004 ssr.. 100 octane is great. should i use it all the time ? thanks. 93 octane from gas station then i added a bottle of octane booster to raise it 7 more points to 100...
My ssr is curently bone stock, however I have had 2 cars with 6-71 GMC Blowers. that being said it all comes down to what has been said before "compresion" That you need to remimber is that as your blower runs faster it increases the static presure efecting your compesion thats where your power comes from. for normal daily driving you would probably be fine with 87/89 octain (depending on your boost) however if your going to the track and winding it out to full boost you will be better off with a higher octaine. Once again depending on what your boost is. most out of the box bolt on set ups for the street are fairly low boost however if you have changed your pully to increase your boost this will make a diferance as well. sorry for draging this out hope i didnt bore you.So using racing fuel in Ilsa (supercharged 5.3) won't help her get a lower ET at the track? I've always wondered about that.
Hi Kenny. Just so you know, this thread is almost 7 years old. You can always start a new thread if you have a question.Can a mixture of say 1/2, tank of 89 and the other 1/2 with 93
Is the 6 liter LS2.motor subject to stalling at lower rpm than higher..
Thank you for any and all feedback
Thanks wizzr.Hi Kenny. Just so you know, this thread is almost 7 years old. You can always start a new thread if you have a question.
But to answer your question, here's what I know...
a stock 5.3 runs fine on 87 octane all day, every day
a tuned 5.3 may require 91 octane.
a stock 6.0 runs fine on 91 or 93 octane all day, every day.
a tuned 6.0 still runs fine on 91 or 93 octane.
if you have a race motor, all bets are off and use what the your tuner recommends.
As stated above:
"Higher octane fuels are not "better" or give "more power" They are just different...higher octane delays detonation."
If your truck is stalling it is likely not the fuel. Do some diagnostic testing.
