100 octane on 04? - SRT Forums

4ceFedBlue&Gold · 01-07-2009, 11:59 AM

is it safe to run 100 octane on my 04?

boost = 13psi stock turbo
pcm = stock
injectors = stock (577cc's)

all other fuel delivery components are stock. i just wanted to know if it is safe to put 100 octane in my car when i go to the track in a few months.

nobody can help me out with this one? i know the Sunoco down the street from me sells 106oct. just wanna make sure i wont have problems running it.

Safe? Yes
Will it do anything in a stock car? No

100 will allow you to run more timing and boost w/o knocking as long as your AFRs are safe.

fix your factory BOOST LEAKS FTL lol

stock sounds so....harsh. lol. my mods are in my sig.

so in other words ur sayin id have to get return line, bigger injectors, and a good tune to make 100oct worth my while?

appreciate the feedback.

not really, just more power adders. Such as big turbo, ported stocker with supporting mods, etc.

100+ octane helps with tuning (correct me if I am wrong anybody)

Having a stock turbo with stock everything will basically just be a waste of your extra buck, thats how minimal the gains/benefits are lol.

you could lean your car out and jack the timing with a mapclamp/piggyback

what would you recommend? i have lots of bolt-ons but the pcm, turbo, and fuel system are stock. what should i get before i go and get tuned?

just ordered one yesterday. should be here in a week or so.

i must be running ok though right? 13psi isnt too much. ive been running that much boost for probably 8 months with no problems at all.

kup@l · 01-07-2009, 04:56 PM

13lbs is fine...

should get your factory boost leaks fixed though!! bet you it will make you feel x1000 times faster than what you feel now haha..but seriously.

Also, I was risking about going lean, but I boosted 17lbs all night and day w/o a wideband. I have one now and it runs fine.

i have a stainless steel hot side IC pipe and the AGP cold side IC pipe.

what other leaks could there be? i really dont feel like there are any.

kup@l · 01-07-2009, 05:04 PM

well if you dont think there are leaks, does your boost gauge sit a 0 when off?

things that me as well as others did

zip tie all vaccum lines hoses,etc.

Everyone but ME and a handfull use t-bolt clamps.

regular hose clamps just does it fine for me

rolla4now · 01-07-2009, 05:10 PM

with the Kinetic WG you should be boosting around 16-17psi dropping to 13-14psi @ redline. that should be the first order of business!
