What are you guys using for these high boost situations?

I'm at .035 and getting horrible blowout above 12psi. I'm going to try .028 tomarrow

 

depends on your ignition. On 20+ im gapped at .030

 

What type of ignition and coil are you running? Most peeps are fine with .035

 

MSD 6btm and blaster coil..

Reallly healthy wires.. can't remeber if i'm using TR6 or 55's

Thanks guys.

 

.025 to .030...

 

Alvin,
If you have TR55's in pull them out as they will be a little too hot for 15PS1. Try some Autolite 103's. I have had better results with the autolite than NGK (some NGK's give part throttle surge), but your results may vary.
Later,
Bryan
I guess I could have just emailed you

 

im running TR6's with a .038 gap at 17psi with no problems. Delteq ignition with no aftermarket box. when i switch to colder plugs in this weekend for the nitrous i was planning to go to ~.030 to be safe though

 

I'm curious, what does it feel/sound like when the spark blows out? I am just wondering since I still have my phantom rev limiter problem on mine...

thanks!

 

Thanks guys for all the input,

and thanks bryan!

It sounds like a bad distributor would or something, just missfiring and the dead cylendar type thudding sound. Kinda hard to describe.

This 15# pulley completely changes the effecientcy of this motor, it now raps up to 10psi pretty freely and with less than 1/2 throttle. Tomarrow i'm going to spend a few hours actually tuning my own car (bryan knows what i mean, when it comes to your own car it feels like work )

 

I'm at .025/.028 with a set of AC Delco's suggested by Kurt from W2W. I ran TR8's for a while but they seemed to foul out kind of fast. I would not run TR6's for over 700rwhp.

 

i agree with not using TR6's past 700rwhp (or 650rwhp IMO). i stuck with them since i was having part throttle tuning issues and fouling plugs for a while, but now that i fixed that i am going colder since the electrodes on mine are showing obvious signs of overheating (without nitrous use)
