Re: THE QUEST FOR 500
I don't use the motorcycle/2 stroke plugs, I only use the NGK r6725 series rotary specific plugs, and I run 11.5's and have had no issues with fouling.

Re: THE QUEST FOR 500
so i rolled a set of b10egvs in the car today , every thing felt great for half the day and then it started breaking up again. I got home and pulled the plugs , the trailing looked great nice and brown the leading was black and wet with oil deposits on them as if they were still too cold of a plug on the leading side? I check the spark and it has a scary amount of it (jumping a 3-4 in gap and purple as can be ) . I run vp 110 and motul 2stroke at a 1ounce to 1 gallon ratio . WTF?

ok them trailing is good then you still have an issue on leading?? ok well can you check the leading system? like wiring,ground, voltage drop , maybe is shutting off |
Re: THE QUEST FOR 500
i was thoug the same thing, but why would it be fne for 10 pulls and then get worse. Im going to put a set of 9's in the leading and leave the 10s in the trailing and see what happens . there was a definet improvement going from the 10.5s to the 10's .

Re: THE QUEST FOR 500
Sounds like you may have unbalanced or leaking injectors.

Re: THE QUEST FOR 500
its all good , Im a tech at infinete velocity motorsports in reno nv. all the tuning and work was done by me prior to steve tuning it, I just wanted to see what he did with the timing maps and to get some dyno numbers. the break-up was never felt but you could see it on the dyno and the numbers werent where they should have been. thanks again for all the input .

Re: THE QUEST FOR 500
Peak power numbers are on the low side because hes not able to rev that high; Gt4088 is only a 63mm inducer turbo...
I agree something else is going on, and its not plug related.. |
Re: THE QUEST FOR 500
so i just called my engine builder to get a build sheet , I was under the impressionthat the engine was 700 hp capable and its got every thing there to do it except it doesnt have studs or dowels? i just started noticing a little puff of white smoke on start up . possible coolant seals hurt .
