Installed P & P LIM
 

My ported and polished LIM got installed today, along with the improved LIM gaskets. We also caught a vacuum leak around one of the fuel injectors. Altogether, car is running MUCH nicer. Pulling faster, but also much more smoothly. Hard to say how much is the LIM and how much is the vacuum leak, but together the difference is VERY noticeable!
Big thumbs up
I'll update in the coming days as to how things are progressing.

Oh, and a big thanks to Andrew for doing the work!

Glad to hear it fit alright. Make sure you go back in a week or two and re-torque those LIM and (especially) UIM bolts...just to be on the safe side ;)

Cool... Did you take any install pics?

And now onto the next Mod :twisted:

It'll come to you over the next 100 miles or so. The vac leak was probably really only affecting your idle quality.

Oddly enough, the vacuum leak made the biggest difference in how the tranny was shifting. Smooth as silk now. Does definately idle better too.
The next 100 should be fun! :)

Grabbed a couple of pics with my phone, so I will see how those came out. Not having had Dexcool in the engine made things nice and clean. Go green! :)

Next mod? CAI or PEM. Leaning towards the PEM....

nice job erik you will feel better throttle response .and did youre LIM gasket or upper look bad .my upper was like new after 10 years but my gasket where very bad looking but mine was on dex all its life .

Sure looking forward to it. Just a nice, smooth pulling engine. Throttle response was definitely better. Andrew does good work! :thumbup:

No problems with cleanliness. I had the UIM done about 4 or 5 months ago, so it all looked pretty good.
My big problem now is gearing. As I have the 2.84 gears, it takes forever to get up into the power band. 3.06 is the answer!

what you can do to fix that a bit its to get shorter tire my stock tire where 26.9 inches now my new tires are 25.9 inches so this lower the car half a inches and help gearing at the same times i know youre where looking for new rim and tires .for me that improve my 60.foot time from a 2.40 to 2.23

Have thought of it, but I don't want to be throwing off my speedometer that much. Drive a lot in many laser and radar infested areas, so having a good speedo is a nice thing. :)

Just as an update,I have been running it for a few days now, and it certainly is stronger. Stronger and smoother, with better throttle response.
Only bummer is that it is a horsepower mod, not a torque mod. Down low, where I need the help, it really did nothing. Again, it is gearing that it killing me. These gears might have been ok on the torquier L27's, but on the L36 they are just way too tall. I am willing to bet the move to 3.06's would cost me nothing in fuel economy. In the Olds, the EPA showed them to be the same. I can see why. Wouldn't have to be forcing downshifts all the time to get power.
Anyhow, all grumbling aside, the P&P LIM is a good mod!

funny on mine its gave me some more low end by the way of much better throttle response and in second gear also i think jr3800 told me the same thing

There probably is some more torque, but I am so dead low down, that I might not be able to feel it. Tall (2.84) gears. Stupid heavy Olds Touring Sedan wheels. Too much lard in my car. Too much lard on me! :)

Yeah you have a Heavy C Body.... and those 2.84 gears are killing you.... The 3.06 would be perfect... I think for your application 3.33 would be a little overkill, But I have thought about it myself....

I have better throttle response, and a little more go in the low end... But it was most noticed with the improvement of 2nd gear pull...

2.84 to Firebuicks 3.05 and my 3.06 is a bit of a stretch... 2.84 is all about the fuel economy
:lol:

Sounds like your a happy camper.
I hope Hawkjet is too when he installs this LIM I sent him.

oldblue are you orgasmdonator on the gpclub that says youre ported intake give 15plus horsepower if so i like to know how you got those numbers

That's who he is over there. ;)

I'd be curious about those numbers too. And at what RPM.

I've made some estimates based on the known restriction area and flow (cross-sectional area) gain, but I hope you're not using my posts and estimates here to brag it up over on ClubGP.

ANd, to be honest, I think it is all about economy in the lab, not on the streets. Instead of just pulling along in whatever gear, I am constantly forcing downshifts. Almost as stupid as the mid 80's V8 Chrysler Fifth Ave's with the 2.26 gears. Rated 26 mpg on the highway. Sure. Maybe at 55 on miles and miles of dead flat road. Real world, the gearing totally killed it, and trashed the fuel economy.
