direct Port Nitrous ?

i totally agree on both you all..

to each their own, if 8 bungs is your thing, good...i would go with 8 egt sensors not widebands.

but reading a plug will tell u more acurate data on my opinion.. if u reading it correctly

there is no such thing as an acurate AFR, ( 11.5 or 12.5 or 13.0 ) u have to tune to where your motor is happy.. and makes the power, it may be fatter or leaner than u think..

i like to go old skool and go with the plugs, good luck

so its not out of the question to run 2 or maybe even 3 different plugs on a motor depending on how each different cylinder plug reads? or is that uncommon?

ITs all common or uncommon depending on who you talk to. LOL

i dont understand your question stew??

but you can put one on each bank to monitor how fueling is bank to bank.. but how else would u know if running at borderline timing?? or too little timing ?? by looking at the timing mark on the electrode.. and going from there.. same thing goes with fueling, but u need one of those tools similar to what doctors use that have a lens to look in and a light at the end of it to really look down in the plug... there should be a thin line on the very bottom of the porcelin as thick as a pencil line just after being sharpend...and should not be very dark as well.. thats called the "fuel ring".. if your too thick you can optimize performance by turning fuel pressure down or changing pills... and watch it go faster and mph better.. = better times..

coming back to the same thing, to me this is the only way u can know HOW and WHAT is happening inside each and every cylinder.. giving u the advantage of the beauty of a direct port .. tune each cylinder..

it dont matter if it is a 150 or even a 500 shot.. it will be more precise during the entire run.. i have tried the same shot on a plate and DP and always went faster by far with the direct port..

but dont mind me i just felt like sharing some info.. Flaco

^^^Great info right there... and thanks Flaco!!

The link a few pages back that Mitch posted is a good write up that touches all the points Flaco just did. If you plan on using N20... your motor wants you to know and check all these things.

i was referring to the plug reading chart where it shows if your plugs are too cold or too hot...if one cylinder reads perfect, one cylinder reads hot and the other cold...should you mis-match plugs to correct each cylinder, or run the same plugs all around that comes to the best average?

ohh yes, i would not stick in diffrent heat range plugs...all the same
