How much torco are you supposed to use per full tank? If you were to add 1x32oz can of torco to an 18 gallon tank of 91octane fuel, what effective octane would you get?

 

The cans of Torco I have don't show 91 mix, just 93. 1 can to 20 gals 93, = 97 Octane, 1 can to 10 gals, 93 = 104, 1can to 5 gals. = 107 Octane.

Extrapolate to; 1 can to 20 gals 91 = 95 Octane?, 1 can to 10 gals. 91 = 102 Octane?, 1 can to 5 gals. 91 = 105 Octane?

I have no idea of what chemicals Torco uses or if the ratio would be the same with 91 as it is with 93 but it should give you some idea.

 

where do you buy it from?

 

We get our Torco from Joel - jbsblownc5 on the forum


Torco Racing Fuel.. Accelerator, Race Fuel Concentrate-unleaded

I had a Lab test a mixture of 10 Gallons of 91 octane mixed with one 32 oz can of Torco, and they got 96.5 octane. So 18 gallons mixed with one quart would give you somewhere between 94 and 95 octane.

I've been using Torco with great success for over 2 years!

You can order off my website.

Hmmmm I didn't think it would raise octane so much. Thanks for all the info

 

The SRT-4 I had would dyno 270FWHP/300TQ with Torco in High Octane mode and 250FWHP/270TQ without. 20HP/30TQ was worth the $1.40 a gallon premium.

 

is this torco stuff much different from buying race fuel of 100+ octane?
I have a friend that always puts race fuel in his 6 cyl turbo supra, but he has 20+ lbs of boost. I wanted to try some race fuel, but thought it could mess something up? any thoughts?

 

As long as you get unleaded gas it should be ok in your car. The higher octane rating won't help unless your motor is pulling timing due to KR.

As for 100 octane unleaded gas vs. Torco, personally I believe 100 octane unleaded gas is better (read: safer) in the sense that it will never mess up your motor. It's simply the same gas that you already use, but it detonates at a higher temp. I don't think you'll find anyone anywhere that will argue this point. I was interested in the effects of Torco mainly because, assuming it's just as safe, it seemed like a much cheaper alternative to mixing in race fuel.

Now for some math:

As jbs says, 10gallons of 91 + 32 oz (1/4 gallon of Torco) = 10.25 gallons of 96.5 octane.

From the following octane mix link:

http://www.idavette.net/hib/fuel/upd...Chart%2090.pdf

If I mix 3 gallons of 91, and 7 gallons of 100, I'll get 10 gallons of 97 octane. Add in .25 more gallons of 91 and I'll get 10.25 gallons of something around 96.8~96.9 octane.


Torco Cost = 6 pack of 32oz for $82.00 shipped.
Cost for 10 gallons of 91oct+Torco = 10 x $3.10 (your cost may vary) + 82/6 = $44.67

Cost of 3.25 gallons of 91 + 7 gallons of 100 = 3.25*$3.10 + 7*$4.40 = $40.88

Since gas prices are so astronomically high, it's cheaper to mix in 100oct racing fuel to get a higher octane rating than Torco. Of course this is all YMMV, it all depends on how much it costs for you to get 91 octane and how much it costs (and how readily available to you) is 100 octane gas. In another thread, 100octane gas in SoCal is going for something like $6.30+ a gallon. I found a place in the bay area that was $4.30/gallon 2 weeks ago when 91 octane at the same station was $3.00. Gas has gone up about 10 cents around here since Katrina hit.

Here's a link to an article that covers all sorts of higher than 91 octane gas alternatives:

http://www.idavette.net/hib/fuel/page2.htm

The basic gist of it is that they recommend mixing in high octane unleaded gas as the best path to take if you need to raise the octane level of the gas you use. However, for those that just do not have access to race fuel, Torco seems like a viable alternative.

 

As a clarification, I've never seen 100 octane in Southern California for less then $5.00. It's now at least $6. Even at $5 bucks/gallon, this would make a 100 mix more expensive then a Torco mix. It is also much eaiser to carry around a couple of quarts of Torco, then a couple of 3 gallons cans of 100 octane. 100 octane is not always avaliable in all areas as well!

I'm just one of many, but I have been using Torco safely for over 2 years now....

 

what is KR?
we've got race fuel here in rochester at delta sonic @ 5$ /gal

"As long as you get unleaded gas it should be ok in your car. The higher octane rating won't help unless your motor is pulling timing due to KR."

 

KR = Knock Retard. In reference to your car retarding timing when it senses knock.

More math:

Let's figure the $ point of 100 octane gas with respect to price equalization to using torco.

As stated previously: 10gallons of 91oct ($3.10/gallon) + .25 gallons of torco = 10.25 gallons of 96.5 octane @ $44.67

$44.67 - (3.25 gallons X $3.10/gallon) = $34.6 / 7 gallons of 100oct = $4.95

Meaning if you can get 100octane for $4.95, and 91 octane for $3.10, you'll just about break even with Torco cost, but still get .2-.3 better octane rating overall.

I'm not knocking Torco. Not saying it's a bad product or it's too expensive. Just putting out an informative post so people can see what's available when they need more than the crap 91oct we get here in CA.

 

you mean to say your supreme isnt 93 octane like the rest of the country (you can get 94 in NJ and PA)???
I knew cali was bad with pollution control and I ve visited many times but with rental cars and never looked at octane since i used regular.

 

What the..... California hasn't seen 93 octane for supreme gas since.... the 20th century? I thought the pathetic-ness of our gas was known to all
