FireHead Posted October 15, 2007 Report Share Posted October 15, 2007 hey allis ther a formula to know what octane you will end up getting mixing fuel with a octane booster just want to know because i cant get access to race fuel. thanks for the help There really isn't an exact formula for such things. It all depends on what chemical you are using to alter the octane............beyond that, octane is poopulary determined via reasearch and test motor figures, which you really can't come up with on your own at home. Octane boosters are a generally a bad deal. If you cannot get race fuel or alcohol, you may need to consider configuring your engine for what you can get ahold of. :thumbsup: Quote Link to comment Share on other sites More sharing options...
dajogejr Posted October 15, 2007 Report Share Posted October 15, 2007 I agree...too may variable for octane booster in a two stroke for me... Tone the motor down on the timing and/or compression to make use of what fuel you have readily available for you... Quote Link to comment Share on other sites More sharing options...
Coupelx Posted October 15, 2007 Report Share Posted October 15, 2007 im with what they said but i have used boosters in a pinch on my old turbo mustang with results (last minute grudge races ) torco is probably the best and is well known. for something local, 104 octane boost (orange crap) or a couple bottles of outlaw octane boost (blue/black bottle) i dunno if i would trust them in a 2 stroke. i would dump them in a 1/4 tank of gas and hope for the best. is e85 available to you? that would be an option since its 105 octane but it requires purging similar to methanol.

Fine point, but it also requires richer jetting...etc., as well, similar to methanol... Quote Link to comment Share on other sites More sharing options...
kawiking Posted October 15, 2007 Report Share Posted October 15, 2007 is there no race car shops in your area ? i run vp's c-12 (108 ) octane...... good luck... Quote Link to comment Share on other sites More sharing options...
Ricehater Posted October 16, 2007 Report Share Posted October 16, 2007 (edited) I read an article in super chevy (i think) they had laboratory tests done with all the popular octane boosters... the results were terrible... if i can remember the best one raised the octane from like 91 to 92.5 or something they're not worth the money Edited October 16, 2007 by Ricehater Quote Link to comment Share on other sites More sharing options...
sredish Posted October 16, 2007 Report Share Posted October 16, 2007 here's one of the only gas additives that is a true octane booster, tested plenty of times. http://www.kemcooil.com/products.php?cId=4 this is the most perfect scenario when race fuel is not available or your sharing gas with peeps who use pump and want to bump the octane level up some for your machine.

Where does it say what this product actually does................... I am still going to bang the drum for the all commercially available octane boosting products are garbage parade. :biggrin: Quote Link to comment Share on other sites More sharing options...
shee rips Posted October 16, 2007 Report Share Posted October 16, 2007 if you have an airport in town then see if you can get ahold of av gas. its 100 octane and quite a few people around here run it. Quote Link to comment Share on other sites More sharing options...
350BANSHEE350 Posted October 16, 2007 Report Share Posted October 16, 2007 ok now this has me conserned i just bought some lucas octane booster just thought i would try it through a couple tanks not for performance gains but i figured it would some what clean it out a little if you know what i mean (jets, lines etc.) its suposed to be good stuff and i would hate to waste the 15 dollars is it safe to run for a couple tanks on a stock bike? thanks oh sorry for asking a question in your thread Quote Link to comment Share on other sites More sharing options...

Don't be afraid to ask questions or share ideas here, even if it's a bit outside a threads scope. Some of the best threads we have had here started out being about something completely different. 2.) If you just want to fool around with octane booster it's probably not a big deal and it may in fact clean you fuel system a bit as most commercial octane boosting products are quite heavily laden with chemicals that are strong solvents. 3.) I will never suggest building an engine to run on a fuel source that is dependant on an octane booster. There is too much variability built into a scenario like that.

Ricehater Posted October 16, 2007 Report Share Posted October 16, 2007 it will not clean anything .. its safe to use but unless you added timing or compression you will not need extra octane and you will not see any performance gains Quote Link to comment Share on other sites More sharing options...
FireHead Posted October 16, 2007 Report Share Posted October 16, 2007 it will not clean anything .. its safe to use but unless you added timing or compression you will not need extra octane and you will not see any performance gains The increasing of octane without need goes back to the prost that you make the most power with the lowest octane gas that will not self ignite (detonate) in the engine. I think if you look at the ingredients of most octane boosting products, you will find many of them are almost entirely strong solvents. However, whether they will actually break up and sort of fuel varnish could be debated. :geek: Quote Link to comment Share on other sites More sharing options...
350BANSHEE350 Posted October 16, 2007 Report Share Posted October 16, 2007 ooh i totally understand that more compression smaller domes is a must but i was just wondering if it was safe to use octane boost for a little without worries lol sorry but it brings me to another question im in the market for a noss head and i was wondering what domes to use? now i have seen a pro design chart and it says at 4000ft a stock banshee has 106 psi and then it says 22cc is 116 or something like that well isnt stock 22cc anyways? so i am wondering how small i can go staying on 91 premium if i had 105 in both what could i go with? im thinking 20cc and plus 4 timing or to be safe 21cc and plus 4 timing thanks alot guys that help me a bunch Quote Link to comment Share on other sites More sharing options...
