Meth injection!
Octane boost

Robert:
That seems quite concentrated compared to the chart Iron Terp listed above.
I am asking because I am a novice.
What octane level are shooting for with the level of concentrate? If I use the chart above as a guide I believe that would equate out to 104-105 octane on a 93 tune??
I am sure I am missing something.
Thanks
where did you tap for the nozzles? i ran meth for years on my turbo's and loved it. i hear too many mixed reviews on a PD blower.

It's a race tune NOT 93
Well, there's a bit of a caveat here. With Torco, tests have indicated that it is not possible to increase the octane of the base fuel above 101 PON regardless of the concentration. This is why I have attached (?) after the 101 mixture. When I race, I mix one 32 ounce can of Torco to 5 gallons of 93 octane to get the max of 101. By racing with 5 gallons of gas, you will also be saving about 60 lbs of race weight when compared to a full tank.

Iron Terp - Thanks for the info. 91 is the best I can get in my area. I plan to get a 91 tune and add some torco to be on the safe side.
I assume there are local dealers for Torco? Need to check out their website.
the only danger you run with torco is that you have to use it with every fill up and its really easy for things to go wrong if you are tuned for 93+torco and you are out of torco and only running 93. Its dangerous with the e85 tune as well but atleast you can store a 93 tune on your tuner and baby it home. either way you have to really plan your drives after going past 16lbs of boost. I have been told that e85 runs around 105-110 octane and also runs cooler so thats why Im going that route.

I have a dual nozzle set up tapped directly into the rear of the blower. I run the meth. injection strictly for the effect it has on decreasing the chance of knock on pump gas with high boost and timing. The mixed reviews come into play when you try to rely on meth to control IAT's........I have a 5.5 gal trunk mounted IC tank and dual fan heat exchanger for that. The other myth is that if the meth stops spraying you will lean out and detonate instantly.....not true....you simply set the tune up to run in the 11.8-11.9 range WITHOUT the meth and then spray down to the 10.4-10.5 range....this would normally be considered very fat but if you are spraying enough meth you will make as much power as you do with race fuel and a leaner A/F mixture.
Some of the guys in the BMC club should look into it.......one common issue betwwen alot of the club members seems to be high boost and pump gas.....cheap insurance with the junk fuel we are all faced with.:beer:
Not necessarily. Like E85, Torco is a little bit of insurance and will allow you to get a little more cylinder cooling due to the increased octane. If you run out of Torco and are running straight pump gas, just be smart with your driving style. If you do back to back runs shifting at 6,500 rpm then you'll be running a bit of a risk. Same holds true for E85 and like the example above, if you're really worried, you can always keep your hand held tuner with you and switch to a more conservative tune if not availble.
Just remember, it's the Wide Open Throttle mode that really increases heat and thus the risk. Just lighten up the go pedal a little bit......

Very well put Iron Terp, I was thinking the same thing. You read my mind.
So 93oct=620hp at 18psi.
101oct=640-650hp at 21psi???
I think that much of an octane boost would be worth more than that. Maybe 40-50hp?

I run 91 and party with a 'street' tune in both cars.
Would tossing a can of Torco in there with a full tank for road course duty offer me a nice margin of protection? How much power will I lose with upped octane and the street tune still in place?

You need to put a can in with a 3/4 tank i believe it is. Just wondering, why do you use 91 and not 93. May as well just go with top of the line IMO

He may not have access to 93 octane.
When I use my race tune, I mix 5 gallons of 93 E10 with 32 ounces of Torco. This gives me 100 octane unleaded. You should not lose any power using more octane than your tune requires.
