maybe as mentioned, using lower nitro content helps runtime, but i use 16% runertime and i bring the car in after a 5 minute qualifier and check the tank to see how much fuel is being used by lifting the car into a vertical position and the fuel level in the tank is just under the tank lid hinge bracket, so there is probably another 3-4.5 minutes left of runtime
i'm using the sirio pipe and whatever shims were in it from the factory.
also the engine runs like a clock and idles nicely when i bring it in and is running 110-120 c temp in my mtx4!
Hey Joe, you might need that extra fuel because your STI is about to be modded KICKASS RACING style. I hope you can handle the extra horse power.And dont worry it will still make run time. You can try it on Sunday.
Bring on the worlds.
Hark my man there is no problem with evo 111 rods, just run good fuel and replace rods after decent run time and you will be ok. I have run 7 evo 111s and have not blown a rod yet, unlike my ols picco based collaris which I have about 15 broken rods in my garage. evo 111 is a very good engine, STI even better.
