Thanks

Good morning Larry, I use the TR6's and regap them a little tighter than stock. I have the F1A Procharger and I have to regap them to .28??? I think that's what it is???

NGK TR6 here as well, gapped at.030 I check them every 5000 miles, sometimes they make it 7500 miles but, check every 5000

NGK TR6's here gapped at .035 w/Maggie install, at 1.99 a copy you can replace em once or twice a year.

TR6's all the way!!!! 1000+ hp on them all the time! as far as gap depends on the boost level.

Can you please elaborate on that a little. Like PSI = (gap)???

0East Tx Muscle Cars

for example, if we have a car at 20+ psi we will run it at .026 if we are at like 7 psi we would set it at .034. 10 psi around .030. make sense? the more boost the smaller the gap to help keep from blowing it out. most of the time you will be good to just set it at .028-.030 AND GO!

Thank you, makes sense. Figured that was the reason why but was more curious on the particular gap size to how much boost to run. Same principal from my nitrous days.

So 5 to 6 lbs. of boost set at .035 should be good to go?

0East Tx Muscle Cars

you should be ok

Wow thanks for the information guys. I installed mine at .030 before i saw the other post. will it hurt anything? No one has answered my question on what they would do with my car if it was theirs. I am looking for my next mod. this F.I stuff is like an addiction. LOL What would some of you do...
See above for car and mods already performed.

Thanks for all your support...

TR6s are in my car....

Blower cam, that should about run you out to the nut with stock crank and rods. After that it's forged stroker time.

Anyone used the TR6IX which is the iridium version? I've had great success with the TR55IX standard copper plug upgrade, havent tried any FI with the iridium plug yet, but had wonderful gains with the other plug, plus alot better throttle response.
