i run like 28 lbs of boost all the time
i thought the more boost the colder plug you need

 

No, 6s are not the coldest, they are hotter. 8s are the next step colder, and I do recommend them if you run race gas and high boost most of the time.

Razorlab, I didn't start running alky until right before I moved, so I don't have much data for comparison. My plugs would foul out rather quickly even before the alky when I would only use 7s. Sometimes, I'd have to keep 8s and 7s, because I'd use race gas and high boost at the track, and the 7s didn't always work. I had to change from 7s to 8s at the track one time. Luckily, I came prepared.

 

Is there anything wrong with running NGK BPR8ES's with only 23-25lbs of boost as maybe an extra insurance??

 

10:1 you have a boost leak....do that before you go swapping plugs and everything else.

Always do a boost leak first then go from there, its cheap and easy to do and is always overlooked

 

when i run race gas it spikes to 30 and tapers to like 29-28, if its holding boost that good i wouldent think its leaking

 

well got the new plugs in heres what i got ,it still dose it but only when i grab 2nd gear,the first 2 pulls i did went perfect 11.2 afr's, held boost perfect, everything went great,after that the afr's droped to 10.0-10.2 and it started doing the miss thing, i did not notice any black smoke when i was doing the pulls.
im going to get a compression tester going to try that out
one thing i did notice is at idle the wideban is reading around 15.0, befor i put these plugs in the wideband would be barried at 17+
do you think im running out of injectors?

 

Running out of injector at idle??? Barried? Come on, man - common sense. The word is "buried," and you don't run out of injector at idle. You're supposed to hover around 14.7 AFRs at idle and low throttle.

A compression test is a good idea, but that's not the same as a boost leak test. You need to do a boost leak test to find leaks. No, you won't see boost leaks in your boost gauge, and no, you aren't holding 28psi to redline either.

 

i dident mean run out of injector at idle that is jus commen sense, i was refurring to full throttle pulls
sorry my spelling is not perfect i have been running around like crazy dont have time to care about spelling
and yes i am holding that boost, its spiking 30-31 droping to like 28-27 wish i could get a vid for you , i have no reason to lie thats jus stupid
if you have something helpfull to say thats great!!! i trust your word as much as i trust buschurs, but if you are going to criticize keep it to your self (not tryint to be rude)
going to do the compression test now be back in 10
anyone got a link to a homemade boost leak tester

 

well did a compression test
starting with #1 cylinder
90 85 80 80

 

here are the plugs

 

ok well i might be typing to no one but here we go, so i put 2 gallons of pump gas in ( i now hate pump gas LOL) the car runs smooth the car runs awasom
i think i know why
