Yes, 100 octane at the pump!!

[Cold_Zero]

well, first off, if you dump high octane fuel in your vehicle and dont up the boost or atleast advance the timing, you might as well just drive around pouring it out the window, cuz thats what your doing...

the whole point of higher octane is so the fuel will resist detonation, allowing you to run crazy boost. if you just pour it into your car and not make any sort of changes, your not doing a damn bit of good.

might as well stick to 93:rolleyes

People get some idea that higher octane give you more power. I am glad someone knows what they are talking about. But at $6/gallon, go to Ace Hardware and buy Xylene or Toluene. It is cheaper and Xylene is a component in gasoline.

[D-UNIT]

??? what the hell is that supposed to mean?

Juice dude , juice. What do you squeeze when you are in a car?? Juice right!! Nitrous = Juice right!! I don't have ''boost'' , but I am running nitrous which is technically forced induction.

Leans out (NO NITROUS ) after 2/3 track = 2/3's of a 1/4 mile. Get it. There I spelt it out for you. Do you race cars or do you just read about them!?! :rolleyes

Well anyway I went to ^^tracks^^ and all I can say is that I JUST WASTED FIFTY DOLLARS haha. My system cuts out worst than 92 oct w/ oct. booster! Half track 3rd gear! The worst part of the night was when the time slip printer broke , before I even started racing!! NO R/T - NO 60ft - NO 1/8 et/mph - no 1/4 speed. Only 1/4 e.t. written on a sheet of paper. Best I hit was a 15.27 e.t. (speedo said 102 mph so that is probably about 95-96 mph). WASTED oh well!! Sorry guys maybe next time I be able to give a more accurate analysis when I get bigger injectors ( the real problem!! not the gas). But for now I'm sticking with oct. booster.

Sidenote: friends audi TT stock = 15.0 et.friends audi w/ $750 ecu upgrade = 14.8 et. lol!!moral = You have to waste money , or you'll never know!! :thinker

[krazy skwerel]

That sucks man. What exactly are you running? Your profile says 91 s13, then it says VG30DETT. Do you have a VG in your s13? If so and you are not running turbos why the DETT? Just curious man. Don't think I ever asked you what exactly you ran.

[D-UNIT]

I've got to change that. You're the fifth person to ask that. Truly sorry for the confusion. The vg is in a nickel dot dime (inside joke that no one gets. HA) ala 510. Not alive yet! And my 91' s13 has a simple ol' KA in it. Something is wrong with it but I can't figure what. so I juiced it.

[D-UNIT]

there fixed it!

[krazy skwerel]

Ok, vg powered 510 seems like a good time. Whats the progress on it? Also I feel dumb now that I think about the nickel dime thing. :batman

[D-UNIT]

haha pretty funny eh, well it is almost in but I stopped cuz of warped heads , blown turbos , no trans (free motor, bummer ). and I got my (for some reason weak) 240.

[Bubba1]

You can still buy 100 octane fuel at most race tracks, but unlessyour car requires it, it's a waste of money. At one point my father used to buy Sunoco 260 (leaded 100 octane) by the 55 gal barrel for his old Ferrari when Sunoco stopped selling it at the pumps. That was a little over two tanks of gas. Expensive and a pain in the butt. He ended up having the timing changed to accept 94 octane with an lead additive so we could use it for trips that required more than a tankful.

I thought Nitrous Oxide was an oxidizor and not forced induction. Sorry to hear about your knock problems. I am sure bigger injectors will help flow more fuel into your combustion chamber and help out. Bigger injectors and a better fuel pump always help out.

Was the ECU your friend bought for the Audi programmable? He MAY need some other modifications to his car in order to utilize the power the ECU is trying to give him.

[D-UNIT]

Yeah that is a big arguement in the forced induction section. Something like oxidizer equals more air so it is forced indution. I don't know. Also I'm not knocking. My system cuts out when a lean condition is detected(the red and green a/f lights stay on solid). Way before knock occurs. Oct booster helped me run it longer , but I always thought it was just a gimmick. So when I saw pure 100 oct at the pump I had to try it down the track. My car cut out harder than before (half track). Sad!! I should have used Oct. booster with 100 oct. haha. But the real problem is that my nitrous nozzle is to big and I was too lazy to swap it out at the track. Plus the timeslip printer was broken so that peed me off the most and I just went home.

My friend just bought the GIAC (garret) chip. Technically it is not adjustable , but you can swap eproms $300 each. But the chip is not the problem. It is his wastegate control module. Before the chip boost would spike at 15psi@3800rpm then bleed off to 10psi the rest of the way up the tach till 8psi@redline. Now it spikes at 20-21psi ( I got it to hit 24psi once) then immediatly bleeds to 10psi still. At the track he said it was hitting 5 psi. Takes foot off gas then reapplies it and it spikes again and bleeds off. We always thought it was normal but now we know there is a problem. His car is supposed to be running 14.6 stock not 15.0. Oh well another 100 bucks to hopefully fix his problem. And a $1000 to fix mine. lol.

ok, my crystal ball must be cloudy. i didnt corelate the term used to describe an a/f ratio to your use of nitrous.

hummn lets see, $40 every bottle fill, or just more gas...i stick to turbos. ive never used nitrous on a car ive personally owned or built. turbos dont run out in the middle of a race.

i guess next time im inhaling n20 and the bottle runs out, ill say im lean:rolleyes

[D-UNIT]

or you could eat at subway ( 6 grams of fat)!HAHA but that is so true!! Nitrous = temporary turbo. It was the cheaper alternative at the time. But now 9 months later I could've had that ball bearing T4 that I'm saving up for now!! Nitrous was good for the short run. I'm glad I bought It. But now I need turbo. With bigger injectors I know I could hit at least a 14.5 with a 75 shot. and that is SR20DET land. bye bye 1000 dollars. HAHA.

I'd love to see you inhale car grade n20. It has sulfur dioxide added in it and it smells like a$$.

This is my kit. Get it. It's awesome. Not a single problem!

http://www.venom-performance.c...0.htm

That o2 feature has saved my engine countless times , h3ll it saved it five times last night haha. plus when I do get turbo , I'll already have that additional 75-100 horses just in case. Don't dis it till you try it.

[IvoryJ30t]

nope, a buddy of mine's father owns a big speed shop here in westchester "automaster's of westchester" and sells medical grade n2o. pure baby. you can inhale it right out of the bottle. also doesnt make that rotten egg smell out the exhaust so noone gets tipped off that your using it. im just biased toward nitrous because the idea of running out in the middle of a race doesnt appeal to me. "sure, ill run you as soon as i get my bottle filled, dohhh"

[DAEDALUS]

Hey D-UNIT, what color is the 510 and how long have you had it? My father owned a light blue (original) '71 for maybe 15 years. I figures there's maybe 200 on Oahu, perhaps yours is the one?

[D-UNIT]

Well basically I think the car "was" light blue. But then it was red then orange and finally yellow. I know this cause when we body worked it , it took a whole day to get all that paint off. Got it eight months ago not runnig for 50 bucks (couldn't resist). Yanked the dead four banger dropped in ( doesn't just drop in btw!!) the vg w/no trans. On the first start all hell broke loose. Coolant started pouring from the heads and the turbos started oozing oil on the compresser sides. That was in june , stopped project nickeldotdime for now. lol.

Hey man you from here? I bet you miss it. It's small but it's home!

[DAEDALUS]

Man, that would be a riot, to see that old mule still kicking with a larger engine! I wonder if that could be it. I drove my dad's 510 from the time I was 15, through high school, and even a little in college. It sorely needed a paint job...the "paint" (dust) just came off on anything that touched it. He bought it for $100 around 1980, then in the mid-90s gave it to my cousin who was in college. She eventually sold it for $400 to a couple of guys who wanted to race it. Don't know what happened after that. Email me the last 4 digits of the vin! I'll see if my dad still has any records around.Hawaii will always be home, but I'm very comfortable in SoCal. There's not a lot of work that I'm interested in there, and salaries in my field really aren't up to par based on cost of living.

[D-UNIT]

Yeah. It's real expensive to live here but its hella worth it. To me anyway. well not really ( "shipping" ). haha.

Sorry dude. I bought it title less. The previous owner(s) must've either stole it our intended to full race only! The interior is gutted. It has a full roll cage , two racing seats.I have searched for the vin plate but they must've "removed" it. I can't register it. I can't insure it. I guess it will never be street legal again. But I'm still going to build it for scca/drag!

[D-UNIT]

Any distigushing marks , dents or dings.

Oh yeah one more thing about 100 oct. gas.You know when you're in a gear that is to high for you're engine speed. Let's say 1000 rpm in fourth gear. Your car bogs and shakes violently right? Especially if your too lazy to down shift and you just floor it. Well w/ 100 oct. My car didn't even start to shake until I hit 400 rpms. Not a plus or gain , but it is just something I noticed.

[D-UNIT]

OMG!!!! I'm such a DA!!! My ignition box died two weeks ago. So I yanked it right!?! Yes , but I rehooked up my coil backwards. I just found out last night. What a idiota!! Bottom line -- my 100oct. testing was moot , cuz I hooked up the coil wrong shoot!!! Retest tommorrow hahaha!!!

[Cold_Zero]

good luck and let us know how it goes.
