Dude.. seriously..


Someone thought he said he added high octane to increase spark.. which wasnt what he said...

 

You can with HPTuners

No.

I never said 'drrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr I think he tried to say it turned up his timing'

Jesus you ******* are dense

I said he wasted his ******* money.

You want me to type it larger?


HEY BUDDY


IN CASE YOU ARE BLIND
HAVE IT IN YELLOW

WAY TO WASTE 20 BUCKS

 

you really are retarded. it's a fact.

 

i dont know what you think would break. My transmission (shep stage 1 rebuilt) has been tested to over 600awhp in multiple cars and the 4g63 has made well over what im pushing. Getting to third gear would be pulling into McDonald's an 1/8th mile ahead of you down the road. Come back when you run 11's. You need to re-read what i said about the gas and accept it as fact because it is one. You can argue it all day but it's like arguing that the earth is flat. You are wrong end of story.

It really doesn't even matter what you are trying to say. I explained to you EXACTLY why you would ever use higher octane gasoline and you said i was wrong. That is proof enough to everyone here that you have no clue.

 

the highest unleaded ive seen was 110

 

exactly

hmm i know the 110 n 112 sunoco race gas around me is leaded... fuel cells. eh. gehy

 

did you increase the timing or the boost?

no?

do you know what it is doing to your cylinder head?

no?


short and simple version. you are doing more harm than good.

 

C'mon guys. Everyone knows octane, boost, and nawss add hp no matter what. The more you add the better. Just throw it on, it'll be fine.

 

ok guys, settle down.

not everything over 94 octane is leaded, if i cross the border into sumas washington i can get 100 octane unleaded at the pump. pretty much anything over that is leaded though.

now, upping the octane is only useable if you tune for it. popular hot rodding just did a dyno test on a zz4 crate motor (350 chevy, around 350hp to 400hp iirc). the motor was designed to run on pump 91. they dialed it in on 91, then bumped up to 100 unleaded, gaining nothing. they tuned the motor for optimum power and gained 7hp. they then put it on 116 octane leaded fuel, and even after dialing the motor in they had lost power over the 91 octane setup.

 

ok liquid nightmare we all know its you...

 

hmmm i wonder why? (see my first post in this thread which the thread started argued against)

 

lol this thread is funny,

 

oh i know exactly why, and it is what you stated. when the fuel is more resistant to ignition you wont get a complete burn (unless the motor is designed/ tuned for it), and by not burning all the fuel you will not make as much power. a secondary problem with this condition is that with a wideband it can give you a false lean condition.

i posted my above info cause people seem to need proof.

 

but you are an idiot

 

:aaron:

 

119? Are you sure it isn't leaded race fuel? The highest unleaded I've heard of is 110 or maybe 112, but 119 may contain lead.

 

heh

pickles

 

it was leaded. reading>you jack

 

Didn't read all 4 pages! Or wasn't that not easy enough to figure out with my reply?

2+2 is also 4

 

while the lead is a pro, the more then likely ogenated fuel mixture your running now is alllllll bad.

if i was you, i'd be in a bit of a hurry to learn what effects "high octane" fuel have on engine thats are not adjusted or prepped for them.

it can get ulgy in a hurry.

the lean condishion is most likely caused by a pre-oxygenated fuel, its vary common to run across as these octane levels, and unless you've got injector control, things go bad fast.

if youre an octane junky, for any of a number of reasons, stick with better known fuels.

such as Torco 110, turbo blue 104, ect. VP also makes some fantastic ****, its used on almost all our development engines because you can get an un-oxygenated fuel at 126-128 octane.

vary hard to destroy a motor on a fuel that doesnt want to burn.

 

nice thread learning alot

 

Unless its been said already! Lead clogs cats, and kills O2 sensors and can damage other sensors if it comes in contact with them. Cats can't burn off the lead and they get clogged.

*DISCLAIMER* If someone has already said this then please disregard this post. Thank you.

 

Bye bye cat... z06 came in the shop after running raceing fuel... Both his cats and all his o2's gone. So not a good idea FYI

 

According to the calculations of the fuel calculator. if you blend 2 gallons of 119 octane with 93 octane gasoline. You are running a mix of 97.33 octane.

is it bad to run 91 in my 2.2? just thought i would ask?
