Thread: sparkplugs

If it is running fine then you answered your own question. One question I have for you is how much KR are you getting?

If you have to ask, you dont know what it is.

Let me put it this way.

Its bad.

Very Bad.

Take the 3.4 off the car before it pops a piston.

You dont have enough flow mods to run it.

What you need is the bigger pulley mod.

because one day your roll into and boost and pop goes the piston and you need a new motor.

i'm suprised its lasted this long.

ZZP has no idea what they are talking about when it comes to what plugs/pulley you should be running on a near stock car.

Stick with the 605.

Also I bet your KR is around the 7-10* range at WOT, where as a stock GTP has around 5-6*, so that pulley is making it worse with no exhaust mods like headers, plog/downpipe.

The purpose of colder plugs is to reduce knock. The fact you can't check for knock and are still asking if you need colder plugs is contradictory. It's something you should be able to answer yourself.

stock GTP's came with 5-6* how do the engines not blow up that easily then?
