Mr. Curious Posted October 7, 2004 Share Posted October 7, 2004 How big of a shot can you spray into the 1UZ with 91 octane? 93 octane? Quote Link to comment Share on other sites More sharing options...
jcm3 Posted October 7, 2004 Share Posted October 7, 2004 im running a dry shot w/ 100 octane and 80 w/ 93 with NO problems at all. Key more than octane is colder plugs and a good fuel system (i running a walbro 255 high pressure). Quote Link to comment Share on other sites More sharing options...

Key more than octane is colder plugs and a good fuel system (i running a walbro 255 high pressure). ← im planning on going with a zex dry kit (55, 65, and 75 shot nossles included) and also buying their plugs. why do you have a pump that can push more? i know that the stock injectors are maxed out at around 400hp, but i also thought that the fuel pump could also provide enough fuel for 400hp. corrections?

jcm3 Posted October 8, 2004 Share Posted October 8, 2004 only as a precautionary measure. On a dry setup the fuel is added by way of fuel pressure. As you go up in hp shot so does the fuel jet (which in turn raises the fuel pressure). On small 50-70 shots the fuel pressure is upped to 70-75 psi. On bigger shots like 100 you can see pressures in the 85-90psi range which WILL strain a older pump. I bought a High pressure walbro so i am assured the pump wont flake on me.
