Did a little tune up on the car today, got lots done and great results. Was having some issues at high rpm (5500+) I am running AL 104'* gapped to 50thou, reset to 45 to see how it goes.
New oil pan gasket (24 bolts plus retainer).
Intense oil presure kit and new oil pressure sending unit (old one always read max).
New mobile1 5-30 oil and new filter.
New O2 sensor, I'm sure the last one was original.
New 3.1" pulley, was worried about knock but the scans are clean (except for a 2* kr at the 1-2 shift and 1.5* at 2-3 shift).
New 160* drilled tstat and zzp e stat (thanks silverbullet )
Coolant flush and new dex cool.
Lots of underbody cleaning (1 bottle of castrol stuff)
3 scrapped knuckles

Made 3 wot runs after I let it warm up around town, had my scanner on all the time too.
The new pulley combined with the fwi sure sings a high pitched note
Ambient temps at 79* the iac only read 90* the whole time I was out.
Car was idling at 800rpm and reading about 155*, it climbed as high as 184* while tooling around and no error msg'* cause of the e stat

Still have a few chores to do before the 2nd Annual West Coast Bonneville Fest but all in all the car is shaping up nicely

great news,

keep going

ill change that o2sensor too, original.


3.1 pulley ......you lucky
you feel a good difference?

Mike, you can drop to a 3.4" pulley with a gutted air box and a 180* stat, you'll feel the power

Just looking over the scan logs and I forgot to post the car is making 11psi now, was down around 9 with the 3.3" pulley. Timing advance was as high as 34* too

I must add to this llittle conversation that PDad got very dirty today (he was in heaven) and I myself got a little dirty too. It is hard work passing all those tools

Sounds like you did a little work. I'm sure with that size pulley it probably runs pretty good, should be a noticable difference over a 3.3". Usually .1" pulley makes a 1psi difference, around that pulley size anyways, so going from 9 to 11psi is about right.

45 thousandths is really small for L67'*, especially with your mods. My dad always ran .058" with rockers with no misfires even on 17psi! When he got the cam he went to .054" and with 14psi gets no misfires, so if it was running rough it doesn't seem as though thats the problem...maybe it was though?

11psi is about what you want to run on a non-intercooled L67. Its right at 11psi or so that they start getting KR, so seeing that your just barely getting KR 11psi is about right. The 34* timing advance was at crusing speeds when it could give you that much without problems, this helps your gas mileage. That much timing at WOT would be a bad thing.

That'* good news PDad.
I have been reluctant to run with the 3.1" without some high octane fuel additive so have only been running with the 3.2".

How easy was it to install the oil pump volume booster spring? Can you reach all the bolts without removing the pan? ....or was that how you skinned your knuckles?

Glad you like the E-stat........that was my secret weapon for the Meet but hey it'* all for the fun of it. I'm confident you will own me this year.

You can access the oil filter adapter without removing the oil pan, you just need to remove the oil pressure sensor (1 1/16" wrench) to get to that top left hand bolt.
Oh and there is no socket small enough to access that same bolt, better have a gear wrench (13mm)
I used a little gm red sealant to hold the gasket so no worries putting the stiffer spring in.

btw I skinned my knuckles on the torque axis bolts located at the front of the oil pan, another tight no socket area

I installed the over size tensioner pulley too, now I have to replace the other two idlers, ones of them is making a noise :?

Crap. So much for a closer run this year.

will greenzilla be ready or are you taking the Honda?

Bill, you better be able to take off the better part of that last week in July.....NO EXCUSES. You deserve Vacation time and you've had notice of this event all year
We deserve your full attention

No Honda'* allowed BTW. ......unless your daughter is driving it.

I will be there as early as possible on Thursday to make sure GreenZilla is ready. I'll bring my biggest hammer.
