Thread: a few vids of my xp cam! and a quick question?

well the xp cam is in along with the gen v blower....runs good considering its on a stock 3.8 pulley (will be putting the 3.4 mps on tomorrow from my gen 3)...

i need a new battery because mine isnt holding a charge and i need to get a maff screen from the junkyard tomorrow since i broke mine lol...

a funny thing i noticed is when i did a bunch of pulls everything was smooth and ran good, but then when i opened my cutout and did some pulls it starting breaking up at wot...my guess is that it may just have been a coincidence and that whats causuing it is either the maff/tb screen being out or the battery being dead and only being able to start if its jumped?

its just weird that the car ran fine before i opened up the cutout.

oh well on to some videos, the vids are decent quality but the sound will be better once i use my other camera. vids where takin with a htc evo 4 g

stock mufflers old setup
YouTube - ‪04 Impala ss l67 exhaust‬‏

YouTube - ‪First start up with the xp cam and gen v‬‏

If you put the TB screen back in it will run better

With it out it can cause the car to run like shat.

yea i figured that much...only reason i can guess why it wasnt doing it right away is because the pcm and fueltrims where still re learning..?

That and the screen smooths out the air so the MAF can get a good reading

a few pics



and yes the intake is tem until i get a new elbow

yea i know what it does, if mine wouldnt have broken trying to take it out id still have one, luckily ill be getting one tomorrow from the junkyard.....

Lmfao it sounds like your car set off the alarms as you drove by. How was the sound change from stock to the SD headers?

Now i know what my car will sound like when i xp cam up. What did you have to change out from your 1.9 rocker setup? Im asking because i have 1.9 rockers now also.

You put stock rockers back in...and yank out the stock cam and swap it for the XP.

On another note...speedo vids!

i wont have to take out my l76 springs for 105?

Yes springs are mandatory for a xp cam..

Yea ill put up some more videos soon, after I get the 3.4 pulley back on tomorrow....a little upset because its breaking up still even with the new battery and maff screen back in. does it around 5k rpms in 2nd....im on my old tune still that I had with my gen 3 3.4 rocker setup...knock free on 19-20 timing, I wonder if I need to re tune or if im somehow running out of fuel? Any thoughts or ideas?

ok so...

-put stock rockers back in
-replace l76 with 105 springs
-then install xp cam


Got it thanks guys.

Hey boosted, you think i could send me a copy of your pcm tune for your 1.9 setup lol

This is pretty much the exact thing I will be doing either later this year, or early next year. However, I think I will be going the S1X route..

04Boosted - What type of retainers did you use?

Most likley the same LS retainers he had on when he had 1.9 rockers. I will be using mines as well.

the four bolts that hold the fuel rail on are good with the upper stud holding it?

You mean without?

Yeah they're fine ya dummy

Well quick update..put the 3.4 on and now it's breaking up worse...i think it's just a fueling issue at this point and that I need to get it on the dyno....any other thoughts?

whoops damn typo, lol maybe injector issue?
