better off using third gear for the pull

 

boh my friend and i dynoed our NA s5 cars in 3rd and 4th gear we had a little choppy in 4th gear as well. i think it coudlbe gear related? plugs were new on our cars. the first sheet u posted looks similar to our cars. the second one is weird. u might have a bad connection to teh plugs, a bad plug, or the wires, or a combination of all?

 

the first one is the speed vs hp and the sec is hp vs rpm and how can i tell by looking at a plug if it is any good and i can see spark around the plugs in the night what that might be and it did that with new plugs too i thought it was just my old stuff but i put new plugs and wires and it still did it

 

Go browse the fsm at www.fc3s.org, it explains how to check all that.

 

i did but i only found out how to test the coils and why whould there be a blue ring like spark around the plug but you can only see it in the dark or night

 

If you can see a blue "glow" from around the plugs, then you have a serious ignition leak. Get new plug wires.

 

the wires where changed at the same time as the plugs and it looked liked it still did it but not as much as the old wires and plugs but this was about may be a year ago so i thiought i might be normal but i know that spark is not suppose to come out

 

some body told me that it might be to much fuel making the plugs do that do you think it can be that or something else any ideas

 

Heres some of my chop up dont know what caused it but one run I did before I put on headers didnt have any chop at all. https://www.rx7club.com/forum/showth...hreadid=123202

 

i just checked and you can see spark right where the wire comes close to the block where the dip stick goes and where the wires are next to each other you can see a little spark too why would spark be coming out and my friends car doe sthis too and can any of you may be look at your car and see if it does it to
