oh yes - i remember the problem from my last visit: during the "unexpected" last testrun i run out of fuel and the engine gets nitrous only at wot - i was lucky - only the head gasket was damaged but we could not finish
Ahh yes I remember now. - 1 or 2 years later i had again a fuel delivery problem - engine runs much too lean and spark plugs/pistons melt -
That's the usual end result, so you were lucky the first time.after that i ordered pistons from you with much stronger crown and since that time i used that sparks -
i found them in internet for extreme race applications - NGK R0045J-10 - i never had that kind of problems again - even during very lean runs because of any other problems with electric, fuel delivery a.s.o. - the engine cannot be destroyed in any way now :-) but if you think these spark plugs are not good for nitrous i take any other according your advice!
Yes they are GREAT for avoiding plug melt downs BUT UNFORTUNATELY they are THE WORST plugs for nitrous use and they WILL BE THE MAIN CAUSE OF YOUR PROBLEMS SINCE THEN!!!!
To anyone else reading this NEVER use these plugs for nitrous use.
Also for your information some IDIOT at NGK USA sent Cecil Towner a load of those plugs, advising him to use them on his nitrous bikes. When I found out (just before he was about to race) I told him to DUMP them but because NGK themselves had advised him to use them, he still gave them a try. Luckily he was running 2 bikes and he fitted these in one and my suggestion in the other for ONE run. Suffice to say that he DUMPED those plugs for the next run. i can mount the 4 pulsoids as you can see on the photo - put the fuel venoms into the 10mm whole where i have installed the nos foggers at the moment and with your help the tubes for nitrous - i will took all fuel pumps and regulators and all nitrous related parts i have with me :-)
I will update you from time to time before my visit and send you photos from parts and installation.
Sounds a GOOD plan to me Manfred - just make sure you have a GOOD battery when you get here and PLENTY of petrol this time - LOL
