i hope your valves are okay!

 

How many nails (plugs) will it take to admit that the TR6's
are just not very good at boost ...

The plug y'all are referencing is the BR7EF I think ... Colder
is what you need ... and check that TUNE ...

 

I think the tr6 are good for stock up to about 2-4# and after that go colder. But I still think in your case that those plugs were blown to pieces by hammering them with detonation. No plug would stand up to it.

 

I am by no means an expert but could it be that the cam on the passenger side is set to give more timing than the driver's side?

 

It seems as though alot of my problems all could come down to this.

"Fact"
Every time I've raced at the track (except once) I had a on and off studdering at WOT 3rd gear. Kind of like it was starving for gas. Sal called it as lean. That doesn't always mean the chip is lean, it means the motor is running lean. SO WHY ????
Now after seeing the plugs, it's ovious it ran lean.
"""IF""" it's not the Chip, what else could do that.
Lack of gas, a bad ejector, clogged fuel line, etc.....
So I thought why not change the gas filter.

WELL WOULD YOU LOOK AT THIS FILTER @ 6200 mi on my 02 L.
I only run Amoco 93 bought form only 2 Gas Stations "EVER"





I guess this could explain it ??

Anyway, tomorrow I will go to Denso IT22 a cooler plug, it will help. I already changed the filter, that will help. I will oviously put some GOOD Fuel Ejector Cleaner in it, That should help.
And I will NEVER USE THOSE 2 STATIONS AGAIN.

 

Broken insulators and green coloration are classic signs of too lean and hard detonation.

It's also not uncommon for fuel filters on these trucks to be clogged at 6k, I've seen it MANY times, especially if you use octane booster. Everyone should change their fuel filters every 5-6k just to be safe.

 

Sal,

How'd you do at the track
Most reasonably this was from detonation. The timing is 15 degrees on side 1 and 17 on side 2. The a/f mixture should be approx. 11.6 to 12.0 max., as it is in all the other trucks running the same program. My truck was not able to get fuel, and it's obvious. My fuel filter is full of sediment, and I believe this had some play in it. I'm switching to Sunoco 94 octane, I already took my pcv system back to stock, have a new fuel filter, new colder, better plugs (IT22's), and I'm going to get dynoed with a wideband.

 

No good at the track today. It was horrible, be glad you didn't come. There were hundreds of cars there, it's a huge mess, like 10 cars broke and oiled the track. I couldn't get traction for crap off the line on the whole two passes I made. Went 102 mph in the 1/8 though

I'm not sure why you only burned on the one side. I've seen people burn plugs all over the motor for really no reason. It can't be chip related, because chips do not have control over banks. At WOT, the fuel is based off programmed tables, but also those fuel values are stacked on the adaptive fuel trims which ARE bank to bank. It could be possible you have something causing one bank to go leaner at part throttle driving, then when you go WOT, even though what's programmed on the chip is the same, that one bank will still be leaner.

 

I READ SOMEWHERE, IF YOU FORCE AIR INTO THE INTAKE ( TRUE RAMAIR SETUP ) , AND YOUR CHIP IS NOT PROGRAM FOR THIS IT WILL CAUSE IT TO RUN LEANER. NOT A 100% SURE.

 

You know I did just put a 4" raim air kit on it last week,
Hmmmmmmmmmmmm ????????????
Thanks for that info, I'll check into it

 

the filter looks nasty, but that certainly isn't going to cause one bank to run lean. You should have an injector flow test done just out of curiosity just to see if the injectors are all flowing equally.

 

Has your intake been off for any reason? I was going to ask about the PVC and if you had installed a breather filter. Looks like you went back to stock. My 01 engine had issues with deck flatness...What do you think about running a cylinder balance test or compression test? Those spark plug pieces had to go somewhere..

 

Hey rob do you have a fuel pressure guage and if so did your pressure drop?

 

man this is getting scary.

They would never work on mine under Wrrnty. The uppers been changed, the lower, the air inductionm chip, by-pass, etc...
Even if I put it all back stock, they'd know and void the wrrnty.
I'm saving that fight for the BIG ONE

I decided to back down 2 lbs of boost, I'll go back to a stock size upper and leave my 4 lb lower on. This will give me a richer tune, and also eliminate any "possible detonation" with the cooler months coming.
It only takes 5 minutes with the Dial UR Boost upper hub I have.
I should have the new stock size pulley by Wed.

I've posted pictures of my plugs before with this tune. What ever happen happen recently and seems to not be related to the chip.
My guess is that clogged rusty filter played a part. As for the missing spark plug parts, I got to assume they got burned up or spit out the exhust valve I HOPE ?

This is soooooooo scary, not at all like the old days "and motors"

here's some old plug shots
My stock ones with 5000 miles and both my pulleys.
MAYBE I SHOULD HAVE KEPT THEM HU ???


Some of my TR-6's just a couple of weeks ago with all my Mods.
No green Tips, AND THEY HAVE TIPS, and they're burning fine



Think about it. I was at the track, at WOT, and a clogged gas filter filled with rusty looking gas. Whats gonna happen ???
It's gonna starve for gas and bog down, IT DID THAT, then go lean because your totally into it with a shortage of gas, IT DID THAT TOO, then toast a plug (or 4 in my case) IT DID THAT.
Sal noted I had a lean WOT problem a month ago when it was off and on the power at the track, I posted many post saying it felt like it was running out of gas. It happened on four differant runs at the track on differant days.

Around town it's fine. Probaly rich if anything.
I'm not going to UNDER ESTIMATE that clogged filter, IT CAN KILL
"in my opinion".

AS for why only one side wen't lean, that is the magic question ?

I think I'm doing enough for now to be safe a while and see what happens as the time goes on. Maybe I'll change the filter in another week or so and see if it's still rusty and nasty.
FIRST I GOT TO GET IT RUNNING AGAIN
