Hey,
I have a couple questions about the GMPP Ecotec Supercharger...
1. It's an Eaton M62 right???
2. How do you tell where it runs out of power??? I found
THIS, and
THIS. Do you just read it like a turbo map or...??? If so, do you have any good links for learning how to read the maps?? Does this also depend on the pulley size??
3. If you know, at what RPM does it start over-revving (is that what it's called) and lose power? Does this also depend on the pulley size??
4. The intercooler that people are running... do you have a pic/diagram?? I'm kinda confused as to how they work.
Now I tried searching and the such but I may have been looking for the wrong terms because I didn't come up with much.
Keep in mind, I'm not stupid, but i'm definitely not an expert yet. I'm just tryin to get enough info to tell if it'll do what I want or not.

I'll answer what I can on this but I'll have to research some of it...
1. Yes...Eaton M62 roots type SC.
2. Generally from what I have gathered the SC will run out of power with a 2.9 pulley seeing 14 PSI. This is due to the reflash and the MAP GM uses...it can only read 14PSI.
3. The rpms range of the charger is around 7200rpms on the engine and then you will begin to overspin it (at least that is how I read the information...correct me if I'm wrong someone).
4. I'll dig up the post from Aaron (PhlatCav) for you after I post this...and if I can't find it send me an email at dntwarman@t-online.de and I'll send you a email with the information as I saved it on my computer.
I'll look for a couple more answers on this to confirm some of the info I write...
Eh...old man with a Corvette now...it was bound to happen sooner rather than later right?

Thanks!!
for #2... Do you know if the charger itself can go higher than that?? Like if I ran HPT and faked the 2 bar MAP??
for #3... Is overspinning bad for the charger or just no/negative power point???
This is what I'm tryin to see...
Would it be possible to get 300 HP off the GMPP Supercharger kit???
I would add...
Aftercooler setup
Forged Pistons
Eagle Rods
Ported Head
MSD-DISII setup (possibly)
Alky Injection (possibly)
upgraded fuel somehow
hp tuners or megasquirt
I saw an Eco on ebay that was in the Red Sedan "concept" car. And it says it was pushing like 250HP with the charger kit so I'm tryin to see if it could be made to get to 300.

Someone correct me if I'm wrong but at cretin point, (7200 rpm) it will start to counter spin giving you no gain in horse power.
and as to the 300hp I would think so cause if you add your stock eco which is 145 and the s/c would put you at around 200hp with 8psi. If you do the max I would say about 241. So you would be close if you add those other mods if not passing it.

#2...I don't know that answer as I have not played or looksed at HPT...
#3...the charger will be in a negative power point if you over spin it...i.e., not making power any longer.
I think a GMPP Eco SC can hit 300 hp...I plan on trying to do that very thing once I return to the states next year! You'll need to port and polish the charger as well I think to hit 300...not just the head!
Eh...old man with a Corvette now...it was bound to happen sooner rather than later right?
Hptuners does not work w/ the eco reflash, its either the reflash or a tune with hptuners not both.
and the tmap reads more than 14psi, On admiral jedis car with a turbo, we recorded 28psi with the tech 2
*************Yea i spell liek wrong get over it*****************

K, thanks.
So basically I'm lookin at a redline of 7200. Ya, I shoulda remembered to put port the charger in there too. No use making one flow and not the other.

Ya, I'd run just HPT. Or get my ECU flashed at the dealer and then use another one for HPT.
I think I'd use HPT over MS just because I can control the tranny a little too.

Really? I could have sworn I've seen here and on the ECOTEC Forums where the reflash only sees 14.5 psi?
Can you give me a link on this?
Sorry to thread jack....
Eh...old man with a Corvette now...it was bound to happen sooner rather than later right?
ive seen it everywhere were it only reads up to 14.5. Multiple places.
But when me and Admiral Jedi switched setups his interceptor guage and the tech2 i have both were reading in upwards of 15psi coming off @ about 28. that was with the saab setup and the wastegate stuck closed. But what do i know. Its just what i saw. Noone knows for sure cause we cant read it.
Wow! That's cool then...like you I thought it was only 14.5 psi!
Hmmm....guess you guys are going to find out soon then!
Eh...old man with a Corvette now...it was bound to happen sooner rather than later right?
yeah the sensor reads more as I have recorded as well but its very hard to say if the ecu is really reading/understanding/compensating it. I can tell you that my car starts acting very confused over 120+mph @ 16 PSI (lots of endless desert roads out here), but I think it has more to do with my injectors being at OVER 120% duty cycle, LOL <------ time for some thirsty new ones. The readings you see on a scanner are nothing more than either commands or inputs. Computers comprehension of what it sees may mean nothing.
