just wondering if it is worth it? for 140 US shipped
i have a line on a set of coils with 8.5 wires (which i dont need)

 

Worth it if you plan on doing future upgrades like a power adder, otherwise on a stock engine, wou won't notice any diff. but a lighter wallet.

 

well everyone dreams of power adders in the future...
im the same way.
so i might as well by stuff little by little.

i bought them.

so my next question is.
when i put them on, do i used the 8.5mm wires that come with, or leave on my 9mm ford ones?

 

They should have the same connectors as stock and you should be able to use your current wires.

At what point (with power adder) do you need to upgrade your coil packs? How far can the stock 4v ones go?

 

I would use the 9mm wires you already have, the MSD coils should be a direct-replacement and have the same terminals as your stockers.

 

I have never had a problem with stock coil packs, the only time they should need to be replaced is if you're running huge (40+lb/hr) injectors or if they're damaged. I've personally seen at least 2 guys running blown Cobras using stock coils and running 11s on them.

 

Well I'm running 42#ers... I guess I should probably look into these.

 

Do you have an a/f guage? Since you're dumping that much fuel into the cyl, I'd say the more spark the better.

 

A wideband is in the works but it is being tuned using one on a dyno. Worked out an issue that I was having (bypass valve was destroyed) and I will be redynoing it on Sunday.

 

another reason i bought these was because, i still think my car is lacking something, so i upgraded wires, and it made a difference with it idles and runs.


i notice sometimes when i winding out gears, that i hear a wierd noise.
its not rythmatic, but like small poping...
that is why im changing stuff.

never hurts to upgrade ..right :2:
