Does anyone use octane boost? It could be my imagination but my car doesn't seem to run the same on this 91 California crap :cuss I know I can buy race fuel but I drive my car everyday so I don't want to spend $5 a gallon :eek: Anyone have any good results with octane boost?

 

I used to use Moroso octane booster in my 68, back when its compression ratio was 11:1. The stuff worked very well and came in 1 gallon containers. 104+ also works well, but I could never find it in similar large containers.

There was an article in yesterday's paper about the octane reduction in CA. Apparently, any gas formulator who wishes to come up with 92 octane gas (without the octane-boosting chemical that is not banned) would need to license a process from Union 76. It sounds like they are the only gas station to offer the higher octane gas, but I haven't swung by yet to check it out.

 

NastyC5,

We are getting 25 cases of 108 race fuel concentrate this week or next week which comes in 16 oz bottles. We were instructed by the manufacturer to use 3 oz. for every gallon of gas which will boost the 91 octane California gas to 98 octane. The manufacturer reassured us that it will not harm oxygen sensors or catalytic converters.

The C5 is designed to run on 94 octane or higher and the PCM resets everytime you fill up more than 5 gallons to run on 94 octane. This all translates to the fact that you are losing power with anything lower than 94 octane, not to mention that your car will knock and ping like a Vegas slot machine.

We know of someone in our local area that is running the 108 concentrate in his 2001 Z06 and he said he gained 6 hp on the dyno. Steve Cole also recommends running it for optimum power. It also won't hurt using it in other states where 94 octane is available, if you want to run over 100 octane fuel.

We will be using it so that the C5 will run in optimum performance. We have dyno numbers now and we will see exactly how much we gained by using it.

Being my engine compression is 11.3:1 and forced using crapgas in Ca, I have been testing octane boosters brands and mixing 100 octane race gas with this lousy gas.
In booster products I had worse performance when using NOS brand then in using the 104+ brand.
Mixing race gas, best results was using 5 gallons to a tank of gas which at $4.10 a gallon is not a cheap route :(

Using any more caused a bit less performance level due to race gas burning slower and denser.

Team:
Have you tried using Toulene or Xylene and doing tests?? :cheers:

 

I'll test whatever I can to find the best performance path with the best cost but both you mention are even more costly then race gas.
We have to find something that is safe to engine and easy to obtain and use.

I've been reading reports that vendors who claim to be making something better then this crapgas have attempted to get EPA to approve their product and are being refused so its only going to get worse for those of us not using a 4 banger engine.

Shawn please keep us updated.

John please do so also, I know you do a of testing :chevy

How can they do this since Sunoco is pretty much the only company to offer 94 octane fuel (and not even everywhere).

 

Guys,

We will keep you updated on the pricing of the 108 concentrate octane booster when we get it.

Outlaw doesn't do anything as we have tried it. It isn't rated high enough to have any effect on the car. The outlaw and 91 octane may have something to do with fouled up spark plugs. NGK's are really great spark plugs so it has to be something else that caused it.

GM recommends 93 or above in the C5 owner's manual, but Steve Cole at TTS mentioned that the PCM resets everytime you fill up to run on 94 and higher octane.

Shawn

 

Shawn,
How much gas do you have to put in for the pcm to reset for 94 octane? Also, if you manually reset the pcm, does it reset the fuel and timing trims?
And some octane boosters don't actually increase the octane in the fuel, some of them have some cleaning agent (chemtool) that "EFFECTIVELY" increases octane rating. Your 108 is not this type is it?

Thanks,
Chad

I'd like to see this work..sounds easy enough to 'install' for sure.

With 25 cases coming, I hope it works, and if it does, you may need a lot more:D

hpcubed,

Steve Cole says that whenever you fill up with 5 or more gallons of fuel, the PCM resets to accept 94 octane or higher.

If the PCM gets reset, everything gets reset.

This 108 concentrate does not have a cleaning agent, but is more of a mixing aid. 108 mixed with 91 will effectively give you the average octane rating.

Shawn

 

Shawn,
Thanks for the info. I am definitely interested in a case because my car runs so bad on the new 91 octane with 11.2:1 compression that I cannot use it without a mix of 103 gas. Let us know when it's available and how the tests went.

Chad

 

Guys,

We just got 25 cases of the Turbo 108 Racing Fuel Concentrate in today.

It is priced at: $6.95 per 16 oz. bottle.

The numbers on it look very impressive. Use 3 oz. for every gallon and it will increase octane 7 points.

Here is an interesting email I got from a local Z06 owner that used it:

My Dyno #'s @ Morgan Motorsports fell 5hp after the Octane drop from 92 to 91 on straight pump gas. I'm working with Steve Cole on my Power Loader. I've gained 6 hp with absolutely no detonation. I'll be sporting the 95 Octane, as opposed to a mix that I would guess was about 93 Octane. I used 32 oz of regular 108 Octane which contains the MMT. Steve hooked up my car to his computer and we went for a high speed test for detonation and spark advance. At wot in third and fourth at rpm's up to 5,000+ rpm, it showed 26 degrees, as opposed to 22 degrees on straight 91 Octane. Also, absolutely no detonation!! I'm going back to Steve this week, or maybe next week, to adjust the fuel air ratio at higher rpm's from 11.9-12.0 to at least 12.5.....this should get me about 5-6 more hp, Also, we'll get my car dynoed at Darrin's place.....R&D, if I remember correctly. The guy you recommended. I expect to be at 370-372 rwhp!! My best dyno so far is 365 rwhp(SAE corrected). 370-372 rwhp equals about 436-438hp at the crank.....

Hope this helps.

LAPD - So for the 108 concentrate, how much would you need to add to a tank of gas (15 gallons) to boost the octane to 94?

 

So this guy is now using 95 octane from the a mix, along with Steve's programming in order to get the hp he lost back or with just the mox?

Steve has told me that he found 6-8 hp in the PCM tuning he does on the Z's.

What other mods does this guy have?

RG

 

Guys,

To answer your questions, you would need only one 16 oz. bottle to raise your octane rating from 91 to 94 octane when you fill up. You pour the octane booser in and then fill up afterwards.

The guy with the Z06 achieved results to 95 octane before the powerloader. He was working with Steve Cole to get a powerloader, but dynoed the car before and after he tried the 108 turbo racing fuel octane booster.

His mods include: Halltech TRIC, TPIS long tube headers, Random Technologies high flow cats, Bassani X-pipe and Corsa Pace Car Exhaust system. The last thing he did was the octane booster and he gained results over that. His next mod is the powerloader.

His case is a good example of what this 108 turbo racing fuel concentrate octane booster can do for the C5/Z06.

We are going to try it out and see if we do feel a difference and we will try to get some dyno results.

Shawn

 

Looking forward to some more dyno results with this mix to rasie octane.
