how much should i add to my tank for racing....
say for a half tank of pump gas.

 

what is the octane for C-16.... 118? 116? And i can do the calculation for you...

 

C16 = 116 octane (C is 100)

 

haha ok [(91x6)+(116x1)]/7= 94.5

formula is [(pump gas x gallons of pump gas) + (race gas x gallons of race gas)] / total gallons of fuel

 

c16 is leaded gas.... it will eventually damage your cat and o2 sensors.....

give VP's Motorsport 103 a try..

 

Are you running a boost controller? If not, there really isn't any point in spending the money on race gas unless you can only get 91 **** at the pump. The ECU won't crank up the boost for you so you'll just burn more money instead of rubber.

 

running a fuel system and about 25psi of boost.
looking to tune with the c-16 just for the highboost(25psi)

 

jemm: will take into consideration what u said and try the VP103

 

If you only mix in a couple of gallons of race gas do you guys think it will still burn up the 02 sensors?

 

umm, ya my buddy carl's evo lives off of 115 octane turbo blue, and hes at 9000 miles now using that gas all the time and his o2s are still not dead, he has no cat on his car (took it off) so all he has tot worry bout is 02s but still they ok after 9000miles of daily driving 115 turbo blue leaded gas

 

C16 is 117.5 octane ((R+M)/2).

 

I dont think it should hurt the 02 sensor if u just use it say every weekend just for racing ..
and then too...it's just a couple gallons you would be using.

 

vp web says its 117. http://www.smithtex.com/VPFUEL.htm my friend runs his turbo honda with c16 and 30 lbs of boost for 550 hp. it sucks to get killed by a honda

 

kool...
same here...
there's a guy with a turbo honda running 30psi doing 11 seconds.
on C-16!

 

Sunoco makes 104 unleaded if you have the ability to get it. You can call them up (http://www.racegas.com/fuelspecs/default.asp) and just ask where the nearest dealer is. I found out mine is right down the damn street!
