This year I've decided that I wont be driving my WS6 to the track anymore (only 3 miles) and I'm finally going to get the spray hooked up.

Just a stock internals ls1 with a MS3 cam. Right now only plan to spray a 150 shot out of an NOS plate kit.

Since I wont be driving it on the street, I'm thinking about changing fuel when I go in to retune here in a couple months.

I can get 100 octane at 1 gas station the next town over, and the track has 110 and 115(?)

Or do I even want to consider something from VP Racing?


My goals of doing this are to:
1) Make the car safer, less chance to detonation, backfire, whatever
2) Will this allow me to spray more, safely?


Looking for opinions from racers and from the sponsors.

Thank you guys!!

you can run straight 100 out of the pump. That is what we do and its fine with the 200 we have on it now.

what about a higher octane, since it's pretty much trailered only now?

if someone things I should run something higher than 100, how will that affect 02 sensors, etc?

I figured keep the stock tank, and Walbro 255 pump, but switch to hard stuff

I mixed in a gallon of 110 octane with some 93 and it caused one of my o2 sensors to go out.

Leaded fuel will take out the stock o2 sensors pretty quickly from what I have heard.

The reason I run 100 right now over anything higher, is because it is easier to get and cheaper, and no need for anything more. You could run that on pumpgas if you wanted and be fine, 100 is better, anything more I think you would be wasting your money. my opinion ofcourse.

Really is this ls1.com...

Problem??

100 will be fine.

You could run a bigger shot with the higher octane gas or you could run a little more timing on the curent 150 shot. If it were mine I would just up the shot instead of throwing more timing at it. Most of the time it is safer to just up the jet size than to push a smaller jet really hard. Make sense?

Im just messing around...I was actually subscribing to your thread so I could see the answer as I was wondering too..

Got any pics of that C6?sounds badass!!

So next question - the 100 octane station is 20 minutes each way, away from my shop.

What about running 93 with a strong mix of Octane booster? I carry a bottle of the N.O.S. brand in my Vette, just incase I get crappy gas. Would that work as well/better/worse? Might be cheaper too. I don't mind driving to get the 100 octane, just a thought pop'ed in my head

JP - I've got some pics, PM me if you want to see them as I don't have them uploaded anywhere.

It's 100% stock looking, base C6....it just has a slight whine to it when it's running

well 100 octane is prob $7.50-$8.00 and if you run 104-105 which i believe is the highest non leaded octane you can get but will cost $10-$13
so i dont think its worth the extra money.
now octane booster... as far as the research i have done, the NOS brand octane booster as well as 95% of the octane boosters out there claim to give you an increase of 3-10 octane points now what most people dont know is it take 10 points to make 1 number so if your octane booster gives you the full 10 points then you spent however much money turning your 91 octane gas into 92 octane gas, not worth the money.
but there is one octane booster i have found that is available in many parts stores and that is hyper-fuel octane booster, it will provide 3-7 numbers so even at the least it will make your 91 into 94 or can make your 91 into 98 so that is not bad.
what i have done when i use my nitrous i use 100 octane with the hyper-fuel and it most likely gives me a definate 100+ octane which is easily good for your 150shot

I've used this stuff before with success, lots of local guys like it for high octane unleaded fuel. A 32oz can is around 20 bucks, just mix it in whatever ratio you want to get anywhere from 95-105 octane. It colors your plugs a little, be prepared for that when reading them.

Hurm, good information guys!

I can get Sunoco Cam2 or 260GT (100 octane) for $6/gal

That Torco Pro Accelerator looks good too.

I need to check out VP Racing also, see what they have that is O2 sensor friendly

Just got off the phone with my friend whose a VP Racing dealer.

I can get the Motorsport 109 for around $13/gal or so.

We also considered C12...which is leaded and either clean out the O2's after each race, or get O2 sensors that are okay for lead. Is there anything, factory fuel system wise that says I can't run lead?

I wouldn't mess with octane booster if you dont have to and you def. dont have to. Why guess what your octane may be when you can know by putting a good fuel in it?

$13 a gallon will get real old real quick when you can run 100 at $6 a gallon and be perfectly fine.

The VP100 (100 octane) was basically the same price as the Motorsports 109.

I figured this way, I wont be pulling as much timing, gain some more power, plus the fuel is oxygenated more, so I'll get a few more ponies there also?

camscam02

iTrader: (21)

you said the sunoco 100 was 6 a gallon? why not run that?

So on a SBE because of the higher octance gas you would up the shot more then 150? Interesting, I ask this because I respect your LSx knowledge. Wouldn't it be a ticking time bomb with more then 150 on SBE?

MetallicaMatt

iTrader: (19)

That was the price another friend thought it was going for...but for all I know it's a few years old

I'm going to see what it really costs. If I can get it cheaper than the VP Racing, I'll go for it.

But the Motorsports-109 by VP has a lot higher octane racing

What im trying to say is if they arent around the same price then 100 will be just fine. But of course, say they are $1.00 apart then go with the 109.
