I just build my motor and I used 8:9.1 piston and bore 20 over. try to see if a ported s/c with this set up will hurt me ?

 

well that low of compression isn't gonna help that blower at all

 

thats what i was think . i'm going to a 2.6 pulley and a intake spacer . so i'm going to put my old s/c back on .also i got my car tune with HPT by chevycobaltss3 run great we meeting up again in about two week to fine tune thats way i'm try to make all my changes now . I have the 08 HHR

 

Can't hurt to smooth the incoming airflow. Personally with lower compression pistons I'd have put something more effecient on it but thats just me.

 

:-Pah hahahahahahahahahahahahaha. . Hahahahahaha r u kidding me. Porting a sc out means fine smoothing airflow and opening it up for more cfm. And less heat.... And ect so of course itll help. Anything to lower the iat2z and create more air at a lower flow of air will help! [/B]

 

ok what is more effecient ? i was thinking that i whould get more boost if s/c was not ported which i think i need because of the low compression piston , my head is ported some also .

 

get a tvs

 

Even if say a engine is lower compression throwing is somthing that pushes more cfm at a lower boost will still help since the volume is larger....

 

I'd recommend it as the best solution, but its $$$.

 

I whould love to but i have a hhr I don't think i have enouth room for it , if I knew it whould work I whould get today

 

Hes also in a hhr and no room.. I dont think itll fit and if it does itll be very close

 

um i know what i'm talking about but that low of compression and a m62 is pointless the m62 cant force that much air your best bet would be to go turbo OP

 

to much money and i don't think i have the room for a turbo i whould try a tvs frist . and i don't know if it whould i think it whould it be close.

 

Considering u think u know what ure talking about doesnt count. Boost dont equal power but more airflow on less boost does.. So say ure maf airflow is 35lbs at 3k rpm and then u compare the whp difference on the same engine and ect with the same.boost level as before and.rpm but the maf.lbs is 40lbs. Which one will have the better.power.curve./ whp..... Makin a product that creates more cfm at less.boost means a safer boost and a.safer.power. Which also means if op were to say get his sc ported and install a 2.6 or leave the pulley that he has now. He will make better power with the port job..... Goin turbo is his best bet it truly is but its a dd and ect.... o][/B][QUOTE=MP Cobalt;5960708]um i know what i'm talking about but that low of compression and a m62 is pointless the m62 cant force that much air your best bet would be to go turbo OP[/QUOonsidering the fact that boost dont equal power u dont know what ure talking about.f

 

what whould be the cost of a turbo? i still don't think i have room for at turbo . i ask a guy about a tvs wait on measurement from him

 

U have alot of room for a turbo bro log style and ect......

 

round about cost

 

I built my first turbo set-up for $2500 (this includes EVERYTHING, even a new 3" exhaust system)... sold my GM Stg2 S/C set-up for $1000, and the GMPP Exhaust set-up for $500.

And I went with the more expensive Vulcan Intake and Equal Length Manifolds (Was $1300 worth of manifolds at the time). Replace those with a $100-$200 LK9 Manifold and a $300-$400 Log Manifold... and that's a huge chunk of change saved.

I just helped my friend turbo his Cobalt - only spent $1500-$1700... and sold his stock S/C stuff for $1000.

And why WOULDN'T you have enough room? They make a turbo HHR... and plenty of HHR's have upgraded to larger turbo set-ups.

 

where did you get it from

 

Get what from? I put my first set-up together myself. Individual parts from many different shops.

 

cool , but i don't have the knowledge for all of that for a turbo . i think a tvs may work on my car , just a few bolts to remove i'm ready to go

 

it will waste money =p

 

whats a waste of money ?

 

A month before I started my turbo build, I didn't know ANYTHING about turbos or setting one up. You obviously have to do some research... that's how you learn anything.

 

there a kit on the fourm for 600. i hear what you are saying been working on this to long seem like i with worng with piston
