hey guys, I'm wondering, if i block off the OMP, what will be a good ratio for premix?? some say 1/2 oz per gallon, some say 1oz per gallon...and what is the best brand to use..??? i know some ppl will say..use search..i did, but i need new updates...need INPUT , not STUPID STEREO TYPE COMMENT!! thanks
newbie..

 

idk how much you put in for completely blocking off the omp but I put in 4-8 Oz. per 12-15 gallon refill

 

emm, anymore input??

 

one ounce per gallon would equate to a bottle per fillup. Thats WAY to much, i tried that and nothing but excess smoky smell.

Now i run approximately 3 ounces per 14 gallons. Im sure you could run more or less, but remember that this is a higher ratio than what racing carts run, and they use that injected oil as a primary form of lubrication and cooling. You can run more if you want, but 3 per 14 is fine for me

 

1 ounce per gallon is a 1:128 ratio (there are 128 ounces in a gallon). Thats the first I heard of a smoke coming from this mixture.

 

We run around 74:1 in our cars (one bottle to 8 gallon fuel cell), and get some visible smoke.
On the street, I run 128:1 with QS TCW-3, one bottle per tankful. No smoking at all.

I have seen the internals of a 70,000 mile engine running 100:1 premix, and it had just some slight carbonation. 128:1 seems to me like it would be about perfect for Hi-Po street projects.

 

Nearly the same as others, 16oz to 14.3gallons. I do get occasional smoke on cold deceleration but that might be from a failing turbo.

 

The general consensus is one ounce to a gallon.

Smoke can be reduced by the brand of oil you choose. Lower ash content will leave little carbon buildup also.

 

I run 1:128 and didn't get any smoking. I know of 3 other FC guys that run this mixture w/no smoking. Make sure you use high quality oil though.

 

thanks guys, now, new problem...
the car start up today Idle fine, but!!!( there is always a BUT!!!) almost no respond when i press the gas pedal. the car will stall and die, now! it's a brand new streetport engine. so i'm letting it idle. all day today, with 1oz per gallon ratio Premix, 1 octain booster.
what will help to make a new street port to break in better?? so maybe i can drive it today... should i keep my rpm around 1500+ rpm??but not more than 4500 rpm? will it work?? cos like i said it will idle fine,, but i can't drive it...going nuts!!!!

 

Sounds to me with my previous expereince, you are running to rich and fouling your plugs? When I ran 1 oz to 1 gallon my plugs liked to foul out easy when idleing for long periods of time. I do 8oz to 10 gallons, RB recomends 3.5 oz to 5 gallons. I also have just broke in my street ported 12a.

 

I premix with caster.

 

I have been using shell low ash injection oil for snowmobiles. I strongly beleive that this oil smokes way too much, actualy smells like a snowmobile.

What brand is the lowest smoke, like a redline racing oil or something. Maybe I will call around to the cart and sled shops

 

I wouldn't go below 8 oz for a full tank.

That is way to little. I somtimes run 18 oz for a full tank and I only get smoke if I rev it when its cold. Change the two stroke your using to a better brand.

Yep Not many people see any smoke with 1:128. I think the ones that are are just using crappy oils.

Nice imput

 

I use Coastal multi-use two stroke oil. Never smoked or stank. Its cheap too. around 1.89 per quart which will do two tanks at 1:128

Check out the last couple of posts to my thread and you can read some testing done on boat engines with different brands. Its really interesting.

i use about half a bottle to a tank. i use valvoline twc-3 two stroke i get a bit of a smell bi tthat could be becouse of the strait pipe.... im not shure. but hey it works for me. i also use the super techj from wal mart for $5 i can get a gal. jug. good stuff.

I run 1 oz/gal.

I run a "hybrid" mixture. 4:1 Synertech and Amsoil 2000

 

do you guys just pour the oil in the filler neck, and before or after you add the gas.

I am curious, because, it seems mine is not mixing thouroughly and injecting more oil at some times rather than others. Would it be advantageous to actually mix the ga and oil in a jerry can

 

i put mine in before i fill up that way the incoming gas mixes the oilas you fill up.

Add premix first then add gas - the gas flow helps distribute the premix evenly.

Half a quart per tankful is an easy way to remember.&nbsp It's usually around 90:1 ratios, but it's not enough to smoke the exhaust.

thats a good way .. to go.. easy for me to remeber that way.. and its probably good about 90:1 for me, beacuse the way i drive my car
