We can probably work something out for the install too. The timing chain assembly is a bitch. Late winter early spring is probably when I'll be getting my head back on at the rate it's taking so far (damn shipping) so that would work out.

 

Sounds good. I'll prolly do cams at the same time then and i'm guessing you have experience with that as well. I found manuals on line but someone with prior experience would be most invaluable. I'm certainly in no rush till snow hits anyways cause I park the car for the winter and that's when I'll be doing all the work. Would you recommend doing pistons and connecting rods as well?

 

hey guys does ur cars idle **** up when u turn on the a/c it makes it rev up higher like when i turn my a.c on my car starts to rev higher

 

does that with stage 2 and stock tune. overidle and underidle spark gets stuck in a bit of a loop and causes that too happen. I usually fix it by losening up the spark retard on the overidle advance there are other things that help but I've had to do it on a few of these cars now.

I'm not doing my rods or pistons... stock bottom end can take a pretty good beating so I wouldn't bother.

The head really is a bitch to do and I have lots of help from someone more knowledgeable than I am.

 

Cool, cause rods and pistons are a lot of money to throw down but i wasn't sure if i would be getting close to their tolerance when I add the 60#, 3" exhaust and cams. Would water injection be a good idea?

 

lol thats weird im just stock just got a cai and megan racing can

 

Bingo, your MAF now reads a certain value while the overall diameter of the piping where the MAF is, is different than stock causing irregular readings. I can show you with the scanner if you like.

I've been running a 70/30 Mix of meth for quite a while. It's a PIA to setup but seems to work really well on my car. Right now I can't run it without the meth or it knocks like a bastard but of course I've increased timing quite a bit.

I say it's a PIA to setup because we saw power loss when we first put the kit on rippin07's cobalt. Almost a 10 hp loss if i remember right and had even put a little time into tuning it. I think he now has it setup correctly so we'll see what it does now.

 

this wont cause any problems will it? if not than its fine and raptor i shoiuld be getting my projectors on thursday hopefully

 

I don't want to run any meth, just water. I heard meth wrecks the s/c, strips the teflon out. With the cx and dual pass would i need it? Or will have to do something for sure after i put all the mods on?

 

He heard it from me, for those who disagree with him - pick on me, lol...

 

Hey Jordan, are you going to be in town this weekend? This weekend (26-28) seems to be working for me so far. I'll find out right away.

 

I wondered about it stripping the coating off of the rotors too. I had a look at mine and there was no coating missing but I've only been using the meth for a few thousand K so it's hard to say. No issues just running straight water at all if that's what you wanna do.

 

The meth injection can infact take off the coating that is on the superchargers rotors, this however, will not cause any damage to the sc itself or affect its performance according to EATON. If you also talk to other supercharger suppliers ( I do) they too say that meth will take the coating off theirs, such as Kenne Bell, Magnuson, Harrop and whipple, however they also state that it does not affect the performance of there s/c's and infact recommend using water / meth injection to help intercooling as it is extremely beneficial.
I like the idea of not running it myself, however after weighing the pros and cons, I am using it.
As Raptors said, first time out lost power, actually lost almost 20hp and it was about 10lb ft of torque that was lost. This happens because the meth injection with the smallest injector I have is richening up the AFR over a full point!!!! and was coming in pretty late.

Now that it is ready for the roller again, I have the maf tuned to 11.9 w/ meth on and will be adding the timing on the dyno as that is where I will see how much I can go before it becomes counter productive. I will be doing this probably this week if I have the time some evening.

Benefits that I have seen so far, my IAT2's used to hit 140 after three full gears from a stop (1/4mile) and w/ the meth on now it only gets to about 122, and that is with back to back runs!! side bonus, is you can rest your hand on the supercharger after a run as it is dramatically cooled ( I spray before the s/c) This alone is worth noting as it will extend the life of the supercharger.

I have run straight water as well and testing has shown that you can add an extra degree or two in timing with straight water as it is keeping the charge cooler. It also has zero effect on your AFR so you wont see a dip in power provided you are not spraying a ton of water.

Hope this has been helpful.. Ohh, and it is completely normal for your idle to come up about 150 rpm w/ the a/c on as it is an extra load on the engine, you dont want it to stall. It might climb and drop a little in rpm as the compressors clutch cycles between off and on. Just to see how much load your AC puts on your car do this little test, go out on the highway and set your cruise to 100km/hr. Look at your boost/vac. gauge and watch where it is steady, Turn on the AC, you will feel the car change a little and look at the gauge when you turn it on, it will show a lower vac. reading (closer to 0 )

 

aight thanks rippin07

 

completely off topic but i seen your car on sunday parked by a yellow tc!

 

Great info. Think for now I'll probably just plan on running straight water. If indeed it is in no way harmful to the sc then could always start blending as i need it i guess. What is the point of having the teflon coating if it is not needed?

 

The teflon coating is there to tighten up tolerances on the supercharger. After doing research on this before (forgot to mention) I found that Eaton states the teflon coating should be completely fine as long as methanol concentration does not exceed 80%. Another fact of water/meth injection is that it increases the efficiency of the blower to move air as the injection actually creates a hydro seal around the rotors to the case. This coating I should mention is not the same as a supercharger (ie:twinscrew etc ) that has teflon ribs on the blower blades. The m62 is not a compressor so much as an air mover.
I have emailed on this subject and that is the information that I have recieved as we do alot of forced induction work and water/meth installs. I have also heard of the coatings coming off with just water while the owner stated that there was no change in performance whatsoever. Honestly, I am not worried.

Yes, I was parked beside a yellow T/C and it was already smashed in the rear bumper. I am not sure if I like it as much.... The grill looks okay but to me looks unfinished alittle and the wheels, while I have absolutely loved them in pics, they are kind of dull and I really like the polished 18's on the S/C cars. Interior well, we all know what that looks like. As for the seats I think I like the looks of them but would have to sit in it to say if I like it.

 

Should be. In fact, my car might be in the shop Sunday getting the rims off, and springs swapped out.

 

and i found out today that i should be getting my car back on monday or tuesday!! i have been without my car for almost 2 weeks! this sucks i dont know what to do!

 

Also, when i added the dual pass and CX H/E i put on a 2.85 pulley. Would i benefit from a tuning? Right now I just have the stage 2 gm tune.

 

anyone wanna buy some brand new never opened 9007 blue 8500k hid bulbs they wont work with my projectos need to find some 10k hid for the projectors h1 i believe

 

Are these the bulbs that were melting everyone's factory connectors?

 

anyone down for a meet before the snow flies

 

im in

 

i have no idea i just bought them yesterday but i found out that i cant use them in my projectors and threw away recipt so i gotta find new h1s
