Please dont flame me when i ask this lol (yes im a noob with modding!) But do cams require tunning?

 

sounds bad azz

any vid reving the engine a bit?>

 

only if u want it to run correctly, and without stalling

2morro

 

Ya i kinda figured, i just ask to make sure. Thanks man, and it sounds mean!

 

the stage 1 cams dont rquire any tuning but is recomended for best resualts. all the others require tuning

 

yeah, factory cams are 232, stage 1 are 238, and stage 2 are i think 250, mine are 272

 

damn, you got the stage 3's.... the turbo grind are close to the stage one grind, more in between stage 1 and 2

here are the specs on the comp cams

-Street (Stage 1) Applications power from 2600-6800rpm .423 intake and .419 exhaust valve lift, 252 intake and 256 exhaust duration advertized (210 intake and 212 exhaust @ .050" duration) Works best with computer modifications not required.

- Street & Strip (Stage 2) Applications power from 3000-7500rpm .440 intake and .436 exhaust valve lift, 258 intake and 262 exhaust duration advertized (216 intake and 218 exhaust @ .050" duration) Requires computer modifications

-Street & Strip high RPM (Stage 3) Applications power from 3500-8000rpm .456 intake and .453 exhaust lift, 264 intake and 268 exhaust duration advertized (222 intake and 224 exhaust @ .050" duration) Requires computer modification very strong power over 5000 RPM

-Turbo Applications power from 2200-7000rpm .423 intake and .419 exhaust valve lift, 248 intake and 244 exhaust duration advertized (204 intake and 200 exhaust @ .050" duration) Wide power range, good power.

-Blower Applications power from 2800-7000rpm .423 intake and .436 exhaust valve lift, 252 intake and 262 exhaust duration advertized (210 intake and 218 exhaust @ .050" duration)

 

okay.... so i'd hafta tune for stage2 cams? wtf.. im pissed... I got the GM stage 3.. and they say i can upgrade pistons and valves and to a GM racing balance shaft and be good for up to 8,000 but i can't get it cam'd cuz the PCM is locked... wtf now im pissed

 

locked?! how that happen

 

GM stage 3 ECU is locked directly from GM so it can't be changed... HPtuners never found out how to lock it and idk if it'll ever be possible

it has the rev adjuster up to 8,000 rpms but i can't go that high unless i get supporting mods... and w/ supporting mods i'd wanna get cams

 

but GM said that the stage 3 is fully programable and is able to control a nitrous set up and that is what voids the warrenty when you install the stage 3

 

how much where the cams and where did u get them

 

idle surging eh?

needs more timing control

 

Well, I changed a couple of the "special" tables.....it stopped it from stalling now, had some idle surge still.....I may try and advance the base idle timing a little more and see how that goes.....and raise the idle speed a tad.

 

those comp cams won't fit the 2.0 huh?

 

I found the best solution is to have as much idle adaptive timing as possible now and raise coast down spark. Also make sure the MAF calibration is spot on in the lowest few cells.

They "fit". You have to modifiy the last cam bearing surface and run them without a cam sensor.

 

465 was the cost

 

 

Sounds nice. Seeing as I will not be able to hide my cams, I figure I will make them even more apparent. My goal is to have people say "whats wrong with your car?" when they hear it idle

 

Sounds like the LSJ I just finished, not bad. Needs a smaller pulley IMO.

 

hiding cams is FTL!! im with cam im making mine noticable as hell lol

 

pointless untill lash adjusters "adjust"

 

Maybe we already found a way to shim them right with the guys machine shop out there

2.6/meth/272 pulls pretty fkn good compared to Als 2.8 and my 2.5 setup.

 

i want to hear this when i get home from work...

 

you have a pm mr man
