Does anyone know if one is better than the other to effectively raise octane? The reason that I ask, is that Klotz is less expensive than Torco. I have read that both appear effective; however, is one better than the other, all else being equal?

Anyone?

Never heard of Klotz... their site shows they're in Indiana, yet the pricing is Canadian??? haha...

I've used Torco and Lucas in my 2014 Camaro 2SS/RS LS3, always had good results with both of those...

^^^ Thanks. I see Klotz listed at Amazon and Walmart online as well. Heard good things about it on the Forum years ago. 1 gallon of Klotz octane booster is $57.00, while a 32 ounce can of Torco is $24.00. That is a huge difference. If they are about equally as effective at raising octane, then the Klotz is a no brainer.

Never heard of klotz either.but I'v ran torco in my built zl1. And using it now on my c7. Works great

Charlie at RPM Motors recommends using Klotz.

^^^I remember hearing back from years ago as well RGT; something to do with it not leaving an orange residue on the plugs, like Torco does?

someone will have to do dynos to figure this out. had good results with torco on bike, but had good results with torco on a 4 wheel vehicle but not back to back on the same motor

edit for certain applications 1 % counts - e.g. buddy got 1% more HP based upon motor oil - if it is peak HP it counts in the mile or land speed record YES- on the street - good luck telling the difference.

My basic question is: are both brands equally as effective at raising octane levels, with all else being equal (quantity of product in relation to the amount of fuel)?

Klotz works very well and recommended by many tuners. Watch out for your paint. Put some in my old 930 Trurbo and paint didnt like it too much. You can tell its concentrated.

Translator

^^^Thanks, that is much appreciated. So did you get a C7, after selling your ZR1? You are referring to not letting the product get into contact with the exterior paint via accidental spills, correct?

I ran the numbers once, and you can get Torco for $293/5GA drum, which is 42% off Torco's 6-pack canned price on Amazon, IIRC.

I've been running Torco for 10 years in my C5, and 7 years in my C6. It's much more effective then Klotz. I run 1 Qt per ten gallons, and get a minimum amount or residue, nothing that really requires changing plugs with any more frequency...

I did the following tests this week to see how bad CA 91 octane is.
Ran a bunch of 40 - 100mph pulls and got all at 6.3 sec. Added 5 gallons of 100 octane to tank filled with 91 which brings it to around 93 and change, all runs were 5.8 sec half second better.
First went out and duplicated 5.8 sec with 5 gallons of 100 octane. Ran out tank and added 1 quart of Torco to 18.5 gallons of 91 octane, which according to chart added 4 points to 95 octane.
Ran two sessions was only to get several at 6 sec and several at 5.9 sec, weather identical 72 F at Sea level. Conclusion, Torco ain't cutting it. Also best times were when Engine was hot.

You have more than a couple of variables here. Perhaps you feel good about your test but who knows if the source 91 octane was 100% equal and barometric pressure along with track conditions.
I'm under the impression that octane boosters are better used when tuning the car for a safe level of timing advance and similar parameters. I talked with one of the forums most know tuners and he said Torco definitely increased the octane significantly and allowed for additional degrees of timing which means big numbers on the dyno. I'm not dismissing your test but dollar for dollar, I think Torco is better than pumping up octane with race gas. I'd like to see testing done in more of a controlled lab setting. Just my wish cuz I'm considering a steady diet of Torco when the FI goes on! Too much crappy 91 oct gas here in Tulsa (the oil capitol of the US). I read where CPR's tuner did the best he could with crappy Arizona 91 oct and could only get 509rwhp out of an ECS C7 with an A8. Don't want that to happen to me.

I sent you a PM so as not to get in trouble again about this stuff.

RGT

Yes that is correct.
