Well my car is up at the dyno about to be retuned and we have hit a snag with the money situation. The car was going to be put on c16 but dont have the funds for it at the moment. So we're looking at alternatives, here locally I can get Cam2 which is 110 octane for $6.99 a gallon, my only issue is I dont know anyone running it nor do I know what sort of power can be made from it.

Setup is a 84mm GSR with 6262 that made 517 on 17psi and pump gas. Would like to make beyond 650 on race gas with about 30-35psi just not sure if 110 will get us there or not...

 

There are a few guys here in central Va that run it with success. I don't know about power figures but it seems to be a decent step up in reliability from 93. One of them was in the upper 500's on it iirc.

 

Why not run E85...probably best bang for your buck.

 

I dont have big enough injectors for corn, I would be maxxing them out without seeing much of a power gain. Only on 1000cc injectors

 

If you pulled very little timing, wouldn't that be aggressive?? Pulling alot of timing would be conservative? What do you consider a "conservative" timing tune?

 

I have always been told that conservative meant not having a lot of timing pulled, is this not correct? Much like running the car more towards rich rather then leaning it out. Maybe I have it bassakwards, I dont remember what the timing was exactly on previous tune but I can ask my tuner and find out if you'd like

BTW I love Honda-Tech /sarcasm... 150+ views, 3 answers and one of them somewhat answered the question haha.

 

well first of all is it an oxygenated fuel? whats the RON and motor octane

 

I believe the motor octane is 105 and ron is 115

why not try the corn and see how it goes man.

i know i told you already but i did make 650@26psi with e85 and rc1000's man it can be done.

what pump are you using

 

Twin walbros in the tank, I know you did. I think in order to make that power we'd have to set the base pressure at 100psi and pray. Looking back I wish I had gone with a bigger set of injectors, but hindsight is 20/20

 

i was at 80psi on my a1000 man

dc was 99% full tilt

 

Haha yeah the 99% DC is what concerns me, thats a lot of stress on the injectors ya know. God I wish c16 wasn't $20 a gallon, last year we could get it for right around $15 at a local motorcycle shop, but like everything else price has gone up.

 

well it should be fine for that power level im not a huge fan of c16 fuel i made 806 on it and i feel there are way better options for the price Q is a better fuel just more maintenance required

 

that motor had over 60 passes on it at the track and of course you know when your not full tilt its not at 99%

 

i get c16 for 12 a gallon here and its still too high for my blood lol

 

Yeah I know its not always at 100% but it still becomes more of a risk vs reward decision. $12 a gallon, **** I am gonna tell my mom to bring some up from NC when she comes to visit next week haha. I guess I will be the guinea pig and see how much power we can make on 110 and if its not enough just retune on different fuel when funds are better then current.

 

i really think you just dont wanna try e85 myself this is like the 3rd thread now on the fuel issue, and many people have mentioned e85 to you lol.

alot of people are scared of it untill they run it, and then they swear by it

 

remember you used to be the same way when you was a virgin then you tried it and said dammmm i like that. same here lol

 

Why would I not want to try it? Its $1 cheapr then 93 octane and makes as much power as race gas. I however do not like risk blowin a motor because I wanted to test the limits of my 1000cc injectors when I can wait a year and up the injector so I can run e85 comfortably. My buddies LS is on e85, friends truck is on it and tuner swears by it, my setup just isn't ideal for it.

BTW this is the 2nd thread I have made regarding fuel, ever


I dont think there was a time as a virgin where I didn't want it haha, availability was the issue back then

 

lol

bro i ran my rc1000's and e85 on 3 short blocks, and the death of all them oil pressure issues. i have never been on any other fuel.

stock gsr short block made over 100 track passes, and was driven on the street for a year and made 589@29psi. that block is still in a car to this day running lol.

even if your scared to run the dc that high then go to 80% and make 600 you should run 10's that way.

 

Car should run 10s the way it sits, damn 60fts I am gonna talk to my tuner today as I still have a little bit of time to figure out what fuel to use. I wish the money trees I planted out back would grow damnit.

 

If you pull timing, you're talking away ignition, hence being conservative.
Its obviously the other way if you add in timing. Being conservative means having alot of "timing pulled", I'm trying to help educate you, not be a dick.

To answer your question, yes, a high octane rating fuel would obviously increase power somewhat..

 

I didnt take your post as being a dick. I know the higher octane will increase power, just wanting to know how much should be expected. I don't want to walk in thinking we're gonna make 700+hp and trapping 145+mph only to find out its 630 and traps high 130s low 140s. Realistically the car was built with 10.5x in the quarter as the goal, however me being a competative person has taken that to "man we need to hit low 10s", part of that is influenced by being beat at events by "true street" cars running low 10s sometimes even 9s

 

depends on timing...

If you're running conservatively 17degrees @ wot, and you go to a high octane rating and can run 24-25degrees, then you will see a very big increase in power.
This of course depends on your tuner's ablitiy, turbo, setup, etc etc..

 

I trust in my tuners abilities and the setup is pretty decent. I think the cams may limit us as they are just 01 ITR's but even then I have seen good numbers being made with ITRs. I guess I will make a decision in next couple hours and report back with numbers and if they are't where I want them to be ill just upgrade parts in order to get there. Sometimes you just gotta learn to work with what you have I suppose
