The stock belt is what's wrong bro. The belt is slipping under all that stress. You need a belt tensioner.

It only happens at 3/4 throttle. WOT it pulls like mad. No slipping at all. I thought it may be slipping as well but when I first got stage 2 and the 2.8 it was fine. It was about a week later when this started for me. And Silver SS started before stage 2 if I remember correctly.

So there are still no "set in stone" answers yet to what is the best gap for each application hah? Maybe Fast06ss has the answers or even Intense.

I imagine it could even vary from plug to plug, brand to brand. I supposed every style is different...maybe that's why so many people say try it and find out. Although I would love a definite answer as well. We may have to settle with that.

This is from Intense's website.


New spark plugs should always be gapped prior to installation. The stock LSJ spark plug gap setting is .045", and that works fine for the lower boost settings. As the boost increase, smaller plug gaps are required to prevent spark blow-out. Following are our dyno-proven LSJ spark plug gap recommendations:

Stage 1 - 3.30" to 3.20" supercharger pulley - .045" gap
Stage 2 - 3.10" to 3.00" supercharger pulley - .045" gap
Stage 3 - 2.90" to 2.80" supercharger pulley - .040" gap
Stage 4 - 2.70" to 2.60" supercharger pulley - .035" gap
Stage 5 - 2.50" supercharger pulley - .035" gap

I wonder how Intense figured out these exact gaps. No way they tested different gaps on all their kits. It sounds like a ball-park figure.

After all the work intense has been doing for the car I believe it to be within reason that they tested their configurations. The thing is what brand of plug did they use unless I missed that part

Ok. I updated the thread to what we know as of this point!

I have heard most people using NGK's but there are also Autolite's.

I don't know what Intense recomends.

They sell the Autolite's. They recommend a copper spark plug.

Yeah and both NGK's and Autolite's 1 step colder plugs are copper. There is also Iridium but I have heard to stay away from them.

NGK's website recommends a .040" gap for a stock SS\SC using BRK6E's.
If the theory for added boost = closer gap, then .035" sounds like a good place to put the gap.

I'm not sure but i took my plugs out last night stock on my 06 they were gapped at .35 so i put some autolight platinums in at .40 and it seems a little smoother but i still have teh hesitation... i have a feeling nothing is gonna fix it

Well... an interesting discussion for sure. My question is this... would colder plugs do anything for us NA guys? Just a waste of money? Maybe go with platinum plugs or something like that?

Exactly how good performance-wise are the stockers?

No need to go colder for stock. Going colder is mostly for blower, turbo and NOS. Or if the compression is bumped up higher than stock.

Matty,

You stated that you have yours gapped at .032 on your Mustang. Are running a supercharger on this Mustang?
