The m62 itself and the intake manifold are both restrictions

 

Past ~450hp

 

Alright that's fine when a better supercharger comes out that's less of a restriction I'll use it... How about that? And a Whipple wouldn't fit I've seen a mp90 bolted on a cobalt in a forum I'll get the link tonight for you guys...

If I'm correct please correct me if I'm wrong the m62 is Eaton and the mp's are Whipple?



Is there anything I could do to the supercharger to become less restrictive? Porting? Both the super and intake? That's would include porting the head intake side though I believe kinda pointless to do one without the other or am I wrong again.

 

And why is it on YouTube zzp has multiple twincharged cobalt running 398whp+ I want 400 bhp not wheel horsepower brake horsepower.

 

I'd say lower until somebody makes good power on the 1900 that we're still waiting on

 

If he doesnt know about "electric cars" then he prbobably doesnt know much about boost either. You seriously need to reaearch about air density and how pressure and pressure ratio are two totally different things. I am definitely against twin charging in your case. You should not do it. It doesnt matter that hptuners can tune that ecu. The ecu itself is not capable of doing much over what it does stock. Its just not what you need. Supercharge it and be done. There are plenty of how tos on here that you can ACTUALLY READ that will help you. Not just read the first post, the whole thing.

 

Okay so if I stick with 40p I'm alright my plan for future would be to get a 1900 then and up it from there... But until then... I think it'll work fine.

 

There is such a big difference dude. You can not just assume it will work out on your car because someone who knew what they were doing did it.

 

I have a friend with a twin charged ion

 

look man there isnt really going to be a newer supercharger coming out. so you have to deal with what you have. if you want a less restrictive supercharger then just go with the TVS. but in all honesty best way to not have restriction, build the motor, port and polish, then run the turbo kit from zzp it will give you plenty of power and spool great as well, not at 4,000rpms. only way to get away from restriction really.

 

How would it not work. I'm putting a lsj head on a 2.2, (strength) capping the cam sensor. Dropping in eagle rods, wiseco pistons, and billet 4340 crank. Comp cams, supertech valves, and 82lbs springs and retainers. And josh f did a twincharged sunfire he was pulling 11.50s on a 1/4 mile so if he can do it why can't I?

 

because he knew what the **** he was doing. you have an idea as to what your doing but you really need to learn a lot more dude. anybody can say im gonna add this, this, this, and this to my car because this person did it. but if you cant drive or you dont know wtf your doing its pointless and your going to start breaking ****. tuning is not an easy task trust me esp on a sunfire/cavalier

 

If you think tuning a twin charged setup is not that hard just because HPTuners supports your ECU you are poorly informed. Given you continue to talk in boost psi you don't have the slightest idea what air density is, what MBT is, or the complications of dealing with a strictly Alpha-N tuning system which most of the older ecotecs use. Even going full standalone you will need multiple days on a dyno to get it dialed in since you'll be starting from scratch. So unless you have about 50k to drop into it, stop right now go buy zzps turbo kit and hope to god your ecotec isn't alpha-N

 

But but all horsepower gains from parts all add together on top of the initial horespower

 

It's an 05.

 

yes you are so correct! im so sorry!! ill be sure to go buy my self a supercharger for my LNF and twin charge it. wonder if i can fit a kenne bell under there. ive seen plenty of guys swap kenne bells onto cars before so it should work. when it does work i should be making about 600hp easy!

 

What's? All parts add horsepower... Not necessarily? Ross and pistons give your strength... Lsj head gives stregth its just build an engine that can take boost... And yeah good point on psi. I don't actually want 25 psi u want 25psi free flowing through the entire engine so "it moves it through the engine quicker" more fuel, air, fire etc.= more power

 

Good luck with, it's alpha-N

 

STOP ******* TALKING ABOUT PSI IF YOU WANT TO BE TAKEN SERIOUSLY

Jesus Christ man, will you ever get it? You need to determine more things about this build including how many lbs of air per min you'll be flowing to get the power level you want

 

Dude not sure if whomever was dumb or stupid. They stopped production of the sunfire in 05... So I have the newest sunfire available. On 06 it was the pursuit and 07 the g5.

 

No idea who the **** this is directed at. But the 05 ECUs are Alpha-N, if you have no idea what Alpha-N is go firebomb your car now because if you don't now you'll want to later

 

And if you wanna be seriously ridiculous my dream car as a sunfire was quad turbo, quad exhaust. 1000% all custom then after a while I knew that was just ridiculous...

 

This guy has to be a troll nothing he says makes sense at all. Not even in an English isn't my first language way either

 

yep hes a troll.

lets lock it up already

 

If it's so hard to tune for twincharging, why is it sooooo easily to tune with just a super and just a turbo?
