Im currently running the Bosch Platinums and at anything higher then 15 degrees it detonates (12:1 CR on 91 octane)...it also detonates bad at low RPMs in high gears, even on 15 degree base timing.

Should I try a colder running spark plug? Any suggestions?

 

Yes...unless I dish out $5+ per gallon of unleaded 103 octane

 

Up here in Canada - we are fortunate and can get 94 at the pump. I was running Denso Iridiums for about 6 months that were 1 temp range colder. I found that the car ran really rough when cold and stalled once in a while. These problems disappeared when I switched back to the original plugs. Maybe you should get a fuel pressure riser?

 

It has plenty of fuel

I think Ill get the NGK BKR7E-N11...I was going to try them but couldnt find them in stock.

 

Is your combustion chamber spot-faced?

Try running less base timing.

Also, the Skunk program is crazy on the timing maps.
Too bad you sold your Hondata. I would have sent you my program I did for my car this past weekend.

 

No, the head is 100% stock, combustion chambers and all.

Im running the Mugen chip, didnt even try the Skunk2 program.
Any idea how the ignition maps on that are?

 

I'm running the NGK BKR7E-N11 in my GSR motor. No problems, had to order those as they weren't stocked.

 

cheap plugs = cheap performance.

 

Val, the Mugen and Skunk programs are the same.. I don't care what anyone says. Same .

I am running the PFR6G-13 plugs in my car.

You should have had your chambers matched.

 

Heh, too bad non of the damn shops around here are skilled enought to do it, rememeber what happened to my B20 head?

Ill try some NGK Platinums next time..Ill order them today

 

NGK BKR7E-N11 better than stocks? Which ones are the best? I am in Miami so I don't have to worry about cold weather, hehehe....

 

Best plugs = PFR6G-11 & PFR7G-11

 

Hehe..are those the $15 per plug ones?

 

I was so close to getting Spoon Iridiums, but I cancelled the order when I thought $140 for plugs....I don't think so

 

pay extra for plugs? or pay extra to rebuild motor due to detonation damage?

 

True....

Just not used to spending over 100 for plugs. PFR6G-11 & PFR7G-11 are better than stock, that's all I need to know.

 

PFR6G11 IS stock.

pfr7g11 is one colder. but i have no problems with using 6s.

as far as over 100 for plugs? these are 12 each.
