no matter how you run the engine (if you have it run in and tuned properly) you will get at the very least 9 1/2 min.


the toro nero also gets retarded runtimes for such a beast of an engine
What pipe and header on toro?

10.54 is very good!!!

Well, I think what I meant to ask earlier on is how to strategize for 10min qualifiers as well as 10 min mains (D,E,F etc etc). I usually pit in in the 7th min and I'm extremely paranoid about not having enough fuel to finish.

Shall I start a new Thread?

you know. this suprised me a lot. a couple months ago my dad was in the process of gettin a new motor. but so he could race i sealed up a mach 427 i had layin around and tuned it. took it to the track made final adjustments. and he did both his qualifers(5 min) and he forgot to fill up before the second qualfer and he didnt run out of fuel. so he decided to run the main(10 min) and he still had fuel at the end. temps were low to. i dont remember because it was months ago but i think it was like 220( + 10 - )

many people diss the mach 427 the losi came stock with but that engine was cheap, it preformed great, and if tuned right can run with the big boys on mileage

Not dissing the mach 427, but i did have a losi 1.0 rtr i bought, to use as a parts car to my losi 1.0 kit, anyways i did run the rtr car on occasion with the mach 427 and i did manage to keep up with some decent engines. had it tuned just right at around 230-250 with werks 30%. However i could not manage more than 6:30-7:00 min runtime no matter what i tried. Same driving style with a os speed and a lighter car, same track same tune etc, etc now i manage to get 10+ min of runtime on most tracks. accuatly i dont think i ran a card reducer on the 427, if you did that explains your runtimes.

Just today got 11:30 to dry..

Ninja B01, EB mods button, 6mm insert, Werks 30%, P4 plug, Dynamite 086 pipe and header.


Same setup with a 7mm insert and P3 plug was getting 9:45.

My car is also 3190g so that helps.
