what optispark?

[JoeliusZ28]

TR55 are a hotter plug and my car ran noticeably better with a TR6 which is otherwise the exact same plug.

I also gap at .035 to minimize resistance.

This is a topic that i got PM'd by people about because everyone likes to argue in favor of TR55s on the boards.

haha try gapping down a TR-55 and see how that runs.

(A TR-6 is gapped at .035" right out of the box)

I did, TR6s are better. TR55s being "the right plug" is bad info thats been spread around for years. Ill run TR6s with or without nitrous.

i am going to have a 100 shot so which one is best for nitrous i mean which ones do you like for nitrous?

[ThreeHonks]

TR-6 for sure with nitrous.

Joel - I think im gonna have to start messing around with a tr-6, im gapping a 55 so low that I dont know if its good. and plus with this new ignition setup I should be able to open up the gap for a little hotter spark. idk, its all really trial and error

I have been running the TR55 for 3yrs with no problem
I also changed Red's car to a regular TR55 instead of the platinum and it ran way better.

[JoeliusZ28]

Im not saying TR55s ever gave me any problems. Im saying my car ran better with a TR6

And yea ryan youre right I might give TR55s a try again when i switch to coil packs. I also checked my notes, im gapping my TR6s at .045, not .035.

damn I'm gapping my TR-55s at .50 why is everyone else running smaller?

[Phantom409]

I'm running mine at .045.

your voltage doesnt run through an awesome thing known as an opti, you can probably get away with more resistance.

Yea I believe factory gapping for the ls motors is 55 to 65, mine are at 60 IIRC.

Edit yup FSM recommends .060 for ls motors.

[DETROITMUSCLE]

thanks for the info

[JoeliusZ28]

bah i need to get coilpacks!

[02redz28]

Ls1 ftw!

[ThreeHonks]

Ls1 ignition/pcm ftw!
