Race Fuel

I have been running a mix of 93/100 and alky with 28#s of boost.Usually mostly 100.Had the alky pump fail twice now so im affraid to run just 93 and alky alone.

how many 55gal drums of VP C16 will you need to use before you could have purchased MeOH injection set-up?

I was thinking the same thing...Doesn't make any sense????

 

[ghall]

If you are using c-16, check out renegade 118. Very similar, but cheaper!

 

[krom]

that sounds like the perfect application for MeOH. or am i missing something

how many 55gal drums of VP C16 will you need to use before you could have purchased MeOH injection set-up? i'm pretty sure c16 use is frowned upon for street use in californi-stan; not that anyone here is calling you in to the enviro-fascists. have fun!

Meth is not legal for street use in CA either.

c16. if ya drive it around alot on straight c16 be ready to change some plugs. ive also run 12 befor aswell with no problem. i tried alky and with 26 pounds of boost i made a ton of runs then one day i got the bearings. my wastegate stuck closed one time and my car seen 30+pounds of boost from a 76gtq turbo on my 24 pound tune. if i had been running pump gas and alky i dont have a doubt in my mind that id have got the motor. this was on the first full hit after a fresh build. race gas only for me

Methanol is illegal for sale as use as a motor fuel in CA for one and C16 will make more power than 93/alky. If anyone is serious about maximizing what they have they could care less if they go through 3 or 23 55 gallon drums of C16.

Hello.. i'm trying to run 18 PSI boost.. do I need C16 :tongue:

If i had anything to do with it and you were limited to some reason to 18psi and wanted to make the most power with what you have you would need at least C16. 11:0:1 compression:biggrin:

C16

Mixed 5gl to 7gl 92 this weekend ran 21lb 0 knock went 12.5 @ 106 at 90.00$ a can in Hawaii I'm going alky

 

[hensleyt]

Ps

my goal is 11.90

 

[Turbo RX-6]

my goal is 11.90

Without anything else to go on..... All I can suggest is, next time don't run it with 12gal of gas...Why add the weight if you don't have to. If I calculated it correctly and you ran with 2gal instead of 12 you can pick up a little over a tenth. I try and drop every lb I can... I know it sounds crazy...Shoot, maybe I am crazy! But it gets you that much closer to your goal for free, and you don't have to do anything!

 

[toofastforyou]

116 octane for me...

Claude. :smile:

I had a similar thing happen to me. The wastegate hose was cracked to the point where it was hang by a small thread. The boost went over 30 #'s. At the time I had 116 Sunoco in the tank , That saved the engine.

I run either VP's C16 or Sunoco 116 octane fuel.

Becuase if you run a stock gas tank with little gas in it the pump will drop pressure.

gallon of gas weighs 7 lbs. 14 gallons is 100lbs approx.. .1 tenth compared to empty.. lean the car out and blow motor up.. you lose 8 seconds and no mph

Agree..

And if running C16 would never allow the motor to blow up... i'd have 23 55 gallon drums.

Anyone question this go to a Buick event and see how many race cars on C16 blow motors up.

I think those that spend 90 dollars for 5 gallons of C16 are either very rich "IF" they race their cars at all, or take their cars to the track once a year and gloat about it the remaining 54 weeks. For someone wanting to go to the track a few times a month.. 200+ in fuel costs.. plus the rest.. its a lot of money.

If your tuned for 20 PSI, and your boost goes to 30+.. your done like fried chicken race gas or not. Only way to save the motor is if the car is tuned on SD and a 3 bar is in place.

 

[jasjamz]

By tuned on "sd" do you mean speed density.

mine was caused by the map sensor hose for the ams500. it was close enough to the down pipe to heat up and blow out so the controler would keep adding because it couldnt see the boost level. it was in loom and all but that didnt save it so i had to drill another hole and run it a different route.

im sure thats true but i just like the peace of mind that i dont have to worry about another fueling system coming on or not while i got all the other stuff going on. same reason i dont run stock lines or double pumpers. but your right about wide band correction.... its the shiznit lol

That may save the motor but if its an engine that is already on an aggressive tune adding 2-3psi will still hurt it in most cases. I hurt mine a few months ago. Boost was 26psi the day before and 29psi in 3rd at the track . I made it to 900ft. Data logs shows no lean spot but #1 melted and #3 was getting hot. For some a 3 bar is not enough either. Without egt probes on every cylinder you dont know for sure whats going on with each individual cylinder. If anything i would have had q16 in there and probably leaned it out even more. It was 93/ 30gph alky. Its a fine line if you are running it hard. You wont be breaking any records if your not going to crank it.

 

[Razor]

Yes. Thats why the alky kits are done on a 3bar

Stock MAF stops adding fuel when the grams hit 255.. that can happen at 14 psi or even less on some motors. So if your tuned fuel wise to support 16 PSI.. and the needle goes to 30.. your done like fried chicken
