I was at the Satty dealer today and talked to their RL Tech guy.

He said, the only aftermarket parts he knows are in the works are a wastegate and a chip. I think he said Jones was making the chip. I don't recall who he said was making on the gate.

He also told me that GM has been running the supercharger at 20 psi during tests with no problems.

take it with a grain of salt. and if you would, why would they have a wastegate in the works for a s/c application, i have my ideas already on why i would want one, but why for our cars???

Not sure. Just going off what I was told by the tech.

Word of advise in the future DO NOT listen to tech's at the dealer...99% of the time they are blowing smoke up your ass and do not have anymore information that you do about the car and the upgrades!

I do hope Saturn/GM starts making performance parts for the Redline/SS in the future...they certainly need to do this to stay competitive with the SRT4!

exactly why i said take it with a grain of salt, the tech at my dealer wouldn't even believe me that they are selling the 2.0 s/c WITH the s/c for under 4 grand...

rumors are rumors...

ill belive these redline mods when i see it.

its a relife valve that is vac acctuated like a wastegate for a turbo. It opens when the ECU tells it to. If that stayed closed you would have an extra few psi. But the computer needs to be changed becuase the ecu will force it to open as far as possible to slow the boost down. So you would need a ECU-Bypass valve combo to add pressure. im sure itll happen real soon.

the problem is that with only @5000 RL made in 04 the call for aftermarket is very small.
but on the other hand when the cobalt comes on line they should be produced in greater numbers and there will be many after market sales items.
face it guys there are many many more Chevy people out there then Saturn people. so they will be selling many more cobalts.
thats what makes us so unique or special or just nuts.
just think of the collector item we are driving around it make you want to put it up on blocks for ten years.

 

[goofyguy]

with low production numbers on our side though we will fortuante enough with a decent resale I hope in the years to come where the mass production of the cobalt will ruin its resale value. Id be happy with a LSD and more boost maybe about 250 to the ground will make me a happy man.

I want 300 to 350 on the ground. That would make ME a happy man!!!

there already is one, only the PCM needs to be retuned to not open the bypass valve to effectively achieve what you are talking about

 

[goofyguy]

then why am I not running 15+ psi yet?!!!

 

[Vita]

again the PCM needs to be retuned to not open the bypass valve

Is this honestly an option given the small SC on the car? I would think that increasing boost at redline will only cause future issues in regards to heat and reduced timing from the computer?
I think the best thing for your cars in the early modding state given the fact the SC is close to maxed would be to get a CAI installed along with a larger TB and a ported SC...from there you can monitor temperatures and timing advance to determine of you can increase boost safely.

Hope that makes sence .

Actually, that is not a fact. Someone did the math and found out what the blower was spinning at and it is not close to it's max. Therefore, we can get more boost out of it before starting to push it to its max...

Care to show me those results? I have personally witnessed a B16A Honda with the same SC on it max out with ever bolt-on cams etc at just over 200whp, given the larger displacement of the Redline I would expect it to be able to hande 240whp or so?
I however do not doubt you can run more boost...but I bet if you run much more at redline you may run into issues unless the SC is ported, just because the SC can spin faster does not mean it should in your given application does it...

Please do prove me wrong!!

b16a - 8000-8500 rpm redline.
ion redline - 6450.

Given pulley diameter and engine rpm we determined that it can spin a few thousand more RPM. Check the thread about "attn michigian redline owners".

 

[Vita]

also, more boost isn't going to cause the increase in heat, smaller pulley will. and again, the m62 at 14000rpm as opposed to 12000rpm will only put out about a 25 degree increase in charge temps.

so allowing the PCM to not open the bypass valve a higher rpms like it is rumored to would be a good way to add power w/o swapping pullies...

I am not doubting the SC can spin more in fact I said it likely can! But do we know what kind of heat it will generate at 6500rpms on the Redline motor with an extra 2-3psi running through it? I certainly think you can run a few more PSI through it...but not at redline, how does the Redline computer regulate long term fuel/timing trims?

Just trying to learn more about your situation .

Thats makes sense, have you guys figured out a way to take the computer out of control in regards to that function yet? How much boost does it bleed off and is their a specific RPM it does this at?
