OFFICIAL Blown 4-banger build updates!
No. I'm focused on being able to drive the car, and not have it sitting on the side of my house. When I focus on power, thats when I'll get the sheet metal intake manifold. Maybe you should get more information before saying stupid things like that.
AWD DSM's have made just over 400awhp on an EvoIII 16G, IIRC. They pretty much have to destroy the turbo to make that kind of power, but it can be done very easily.
You should be able to make at least 450whp with pump gas on a Hahn Super 20G... and that'll cost you just under $1k.

tdo6 exhaust wheel and that still has the same tubrine shaft size. the only difference in the 2 turbos is basicly the compressor wheels and cover. You will need to run 25psi plus to make that horse power on a 20g. I ran both 16g and 20g on my dsm for quite a few seasons and they never failed. I ran 28psi on my 20g for almost a whole season at the track and the turbo never failed, and the 16g saw 25psi pretty often, no probs. That turbo is definitely not going to make 450whp on pump gas with out some KR issues, it's just not a good turbo to run high boost and 93oct., race gas maybe. The compressor wheel is just to small for high boost on pump gas. Good Luck
Yeah, my longer gears, and far superior driving skill, should make for a good race. I estimate in good weather with a 2.4L intake mani, I should be around 180-200 whp, and probably 160-170 wtq. George has intake and exhaust, so he's probably around 225 whp and 210 wtq. However he has a 6500 rpm rev limit. So he will shift out of first at ~34 mph, and out of second at ~64. I have an 8200 rpm rev limit so first gear will end at 45 mph and second at 87 mph
Should be interesting.
Also George has full interior and a supercharger. Mine has no blower, a light weight intake mani, no plumbing for the blower or A/C, AND it has no stereo equipment. Less weight FTW!!! Plus, less torque = better traction.

I am excited too. I am kinda excited to hear my car NA. Its got 3 inch exhaust with 2 resonators and a big muffler, it was still loud as **** with the blower, but NA it should be much more quiet.
I don't think so.
Air flow = Volume.
Supercharged = Lots of air flow with no exhaust restrictions = Super ****** loud
N/A = Not nearly as much air flow as SC = Much quieter
Turbo = Tons of air flow, but a huge exhaust restriction = Bad ass sounding

Just picked up two used TD05H-14B turbos, gonna buy a couple rebuild kits for em, and then decide what I wanna do with em.

Flow Rate @ 15psi:
TDO5H-14B-6CM2 = 405 CFM
Max Output:
TD05-14B (stock 1st gen) 275-300hp @ 21 psi
Lets multiply those numbers by 2...
Flow Rate @ 15 psi = 810 CFM
Max Output = 550-600 hp @ 21 psi
I'm liking where this is going, perhaps I will be the first RUNNING twin turbo cobalt...

nice cam good luck
first cobalt ss/TT
I don't really have any reason to port them. If I run 24 psi, I'd be making like 650 hp. I am going to give them to the place I used to work at, they will balance them for me. I will probably port the housings just for the hell of it.
