The BPR7ES were working fine at up to about 21/22psi with the COP at .028. They worked fine at same gap and same boost before the COP.

But I wanted to clean up my engine bay and run the COP. And its been working aces no misfires but didn't go past 22psi.

I installed the BR8ES more to see if can get knock down a bit and run more timing and leaner. As said more experiment until get the meth injection on there ,likely not till next spring now.

They are working not bad but getting misfire past 6500 or so at around 21 psi but also didn't check or change the gaps from the factory packaging. So very likely they are over .030.
I got a new more precise gapper today that can do .025,028 and .030. Will run think .025 or .028 as the BPR7ES were working at that gap with the COP at the same boost level. I won't be going to 25 or more psi till next year and then if necessary an aftermarket igntion box will be added likely aem or crane hear good things about both of them and bad things about msd these days.

So keep you guys updated.If weather is reasonable then likely gap the plugs tommorrow.
But this is Saskatchewan!

Ok took out plugs and gapped to around .025/026 figured since going to run direct port next spring might as well gap down a bit. I have my boost at 21/22 or so and it pulls to redline every gear no sputter or misfire don't miss a beat and car is screaming fast. I still do have my timing down a bit around 5000 to 6000 but then it ramps up although still only 13 or 14.I leaned out my afr to around 10.5 to 1 and its near 11.0 again past 6500 or so.

So if the BR8ES don't foul out from around town driving they seem like they will work good. I saw no knock at all and always seemed to have some with the BPR7ES. So they might be a good thing to try.

I also have to say I know the car is faster at 21/22psi with a bit less timing from 4000 to 6000 then it was at 1bar with more timing. So right now I have to subscribe the theory of boost,timing and afr order of more to less power.
As also said to me more timing seems to really help the torque, leaner seems to make the car just crisper. More boost well it just makes the car faster period!
The car is pretty scary fast right now and the colder weather dont' hurt either.You don't have a lot of time to watch anything but the road and the tach and getting a shift light so don't have to watch the tach!

This car and combo has my utter respect now. It is not a playtoy but a weapon.
A cruise missle comes to mind.

No more experimenting until next spring.But have to say if the car never got any faster than it is right now I would likely be more than happy with it.

Good to hear your getting your issues sorted out. Do you already have a turbo timer? If not check out the HKS Type 1 its got abunch of extra neat features one of which is a dual stage shift light. It beeps and flashes the screen red instead of the usual blue. I have mine mounted on the top of the steering column & it works really well.

Hmm..got an apexi turbo timer. That does sound like a good feature on the hks one.I am buying this new autometer shift light its same size as 2 1/16 inch guage and it will match my other phantom guages ,also getting autometer phantom guage wideband as well.
A shift light will be a good thing for sure ,man these things rev fast as heck!

Hmm put car away but before I did was driving it for last cruise of season. It started up good first time and again at gas station but then went for some groceries and when came out it didn't seem to want to start. Wondering if those BR8es are fouling out already? I have been boosting it up pretty good though not just idling for long periods in traffic.
Guess see how it goes in spring. Plugs are cheap so no big deal there.

All that wondering...
Just pull a plug and have a look?

Plugs may be cheap, but not if you are changing them every week...

Yeah good idea.just pull one..do that in spring but maybe they would foul and then clean off after starting it and driving it for a bit? The idle is perfect though.
Thought read in another post about big injectors not being so good in really cold weather?
I have 950s if that matters.

And yeah Noah if they start fouling all the time would go back down to a BR7ES.But the 8s are working nice for knock for me and pretty happy with the current pump gas no meth injection yet tune.

An 87 post long thread about what plugs/gap should be used.

I'd hate to try and search through this if I was looking for information later on.

Can we come to a conclusion and let this die?

please?

Conclusion..well the plugs were working pretty good added some timing and leaned it out some and didn't see any knock. But had the one incident yesterday of car not wanting to start right away but not 100% sure it was plugs and with car put away won't really find out till next spring.
Sometimes things are not exactly black and white.
Also since using COP now its possible plugs might foul in my car that wouldn't in non COP factory setup. I still also might pick up spark amplifier over winter. I am not giving up on my COP I like it.

What's all this BR and BPR crap?

loose the resistors BP7ES motor cycles,, ect plugs.

more bang than R plugs

less chance of missing if fouled

BUT, the spark is not as long ( lenght of time dumb dumb)

Here talk about this for a couple pages ( where's my spoon, geez I'm an asshole)

no really

Umm not sure what you are tring to say there
Brett.I don't think running non resistor spark plugs are a good thing,think it would interfere with my dsmlink and possibly stereo interference.

I am just fine running the resistor plugs.
As said mostly an experiment for now to see how far can push things without my meth injection system installed. Just bored.

you won't have any problems thats all I've ever run and is what some others run as well, you might have to relocate your dsm link to the trunk to avoid interferance but it is worth it!

it's what Peckerhead usses!

Hmm let car idle today and tried a bunch of restarts and had no problem starting the car at all. Not sure what was up the other day maybe cause it was colder out? Will as said do more research on the BR8ES in daily driving next spring.
