I agree with you all the way. 350whp is enough to take your car into record territory w/ trap times (as a street car). I think there are too many people that want 500+whp in their FWD cars and not knowing what a 500hp car feels like in the first place. I'd say, go drive a new 06' Z06 and I mean REALLY TEST the car to it's limits. If you still want to go faster..then you should think about making 400whp and 200lb weight reduction in your Balt, then you'll go faster. Those of you who are trying to make 500+whp...I don't think you know what your in for. It's not a muscle car, and it aint RWD, so 500hp in that car is gonna feel like 800+ in a RWD, 3500lb muscle car. Watch out, that's all I can say. Torque steer is gonna be rediculous, w/ or without the Quaife LSD, and your "built" motor is not gonna be out engineered by GM, period. The motor will not have the same quality. Just my 2 cents.

 

Exactly the same thing I'm looking to do. When you get the money you should let me know. I'm looking for around 350whp as well. Low 12's sounds good. I'll have 2k around January and if you have your setup done by then I'd be more than happy to drive up to Michigan and have you hook me up.

 

if someone buys my damned shifter ill buy the turbo today lol

djt, I'm glad you already have some of the supporting mods, but realize that you had no list in your SIG as to what you currently have.

great you already have HP Tuners, 60lb injectors most likely a smaller pulley as well, I don't know what else.

but to come out and say that your plan on twincharging for under 1600 WTF

you've already spent at least $900 for what you already have.

now if your saying for an additional $1600, (buying a used turbo, labour and tuning your self)

then maybe. but you don't need to twin charge your car to get it to 350WHP.
my set-up alone is expected to push me over 300, and thats being conservative. which is why I reconsidering the size of my pulley.

Why, you ask, because of the pistons, I'm not about to spend all this money on the car, and push it beyond the capacity of the pistons and risk blowing the whole motor.

but maybe Keith could shed some light on the Pistons and there limit, seeing as he has access to all kinds of info, and GMPD help. cause I'd personally love to know how far I could push the stock pistons. word is no more the 300 safely.

but to my other argument if 350 is your goal, you can do it better, strong and safer then twin charging.
but if twin charging is your goal, then go for it. but 350WHP on stock Pistons, best of luck

 

well for those that dont know:

2.5" pulley
K&N CAI
60lbers
Cat Delete
Hp Tuners
Traction Bars
JBP CAB's
Cobra H/E
PLX Devices m-300

I want to trap 115 at least

2 options...I had nitrous before and wont use it again

1.
Waterinjection+full exhaust
maybe 40-50 hoorse gain at most
figure a full 3" (2.5 wont flow enough) costs atleast 1k
Decent water injection is 3-400 then the cost of methanol to run constantly

2.
Twincharge
200 turbo
200 manifold
550 3" catback
leaves 550 for miscelaneous underhood piping
twincharged already did 330whp
turbo will be plenty big for more hp if needed
no methanol needed
less stress on blower since wont be overspinning it anymore

My reasons

and i feel our cars will take 400whp+ before we need internals...there is another sport compact out there that does and we have better connection rods and the same style of pistons

 

350whp will be easy to achieve...twincharge (RL forums) reach 330whp and that was after some mild tuning with HP Tuners. Dan, I bet you can get 360+ easily.

 

your a little inconsistant with the price of your 3" exhaust in the two optioons.
and what car has the same pistons as the cobalt that is running 400WHP+. please remember that the same style pistons does not mean the same Pistons,
I'm only saying this, because it would be a shame to be wrong. I'd love for you to be write, because then I'd be looking to reach my goal alot sooner and cheaper.

Best of luck man I hope your right.

 

Any real track times or dyno numbers on your car?

 

there is alot more to twincharging your car then just bolting the parts on

you will need more then the HP tuners system as well.

your map, maf and a few other sensors will not be able to play properly without a full standalone computer in the car. hp tuners is not a full tuning and adjusting system for the ectotec engine.

if it was they would be selling them as stand alone systems.

there are many drawbacks to the bottom end of these vehicles, but many good things as well.

we are currently building our turbo 2.0 block with 2.4 head and all GM parts from the build book, we will dyno at about 450whp just turbo

twincharge is cool and all but not great for speed, you puttin your small little junkyard turbo on a car with a supercharger defeats the purpose of twin charging.

the supercharger is there for torque and low end spooling for the turbo = less boost lag

little turbo = less airflow causing problems.

my cobalt as full fmic and all the pipping all the way around, one you add fuel, exhaust, and bov, and tuning software you are over 2500 used or new to do it right.

fuel is a huge issue and tuning is even worse on a twincharged. the computers see many different thigns and get confused easily thats why most go standalone not to worry about anything and to have full control.

350 is a realistic number with a 16g-20g or t3/t4 turbo on the end.

just remeber there is hardly enough room for the 16-20g's that we have used, let alone the size of a t3/t4

the internals of the car can withstand 300-350whp pretty much all day depending on how hard u are running and what u are running at.

internals for this car are very easily accessible now and you will see alot of builds going into some pretty crazy stuff.

stay tuned for info on our solstice and sky as well as RHD Cobalt as we get closer to finishing these systems completely

Thanks again

KEith

 

3" catback is 550 from ttr

cti 3" full exhaust is 1100+ vibrant will be like 1300+

srt-4 to be precise

 

hptuners reprograms the stock management...which runs the engine right fine...gm trusts it...and u obviously havent played with it if u say it isnt total control...

the car will handle 21 psi just fine...does fine now...twincharging will just change how the boost arrives...the more u post this the more this leads me to believe ur talking out ur ass

that junkyard turbo is as big as or bigger than a 20g with a more efficient design flows 65-70lb

why the hell do u have a rhd cobalt anyway

 

i have a right hand drive cobalt because you cant, and i build my own cars from start to finish. well maybe because i also have a 2004 Vortech Supercharged Ion, 2007 Saturn SKy, 2006 Supercharged HHR, and 2003 Yukon.

I build my cars for business purposes and beyond what street tuners do, this is my carreer and my job to go out and push the GM market as best i can and further make GM a better vehicle in the Sport Compact Industry.

The next paragraphs may contain some attitude please dont read if you cannot take just reading material as non harmful, not meant as harmful towards anyone

talking out of my ass? how many design awards have you won from General motors on vehicle and planning in the sport compact industry?

how many cars have you built that you have actually raced?

cause it sounds like your talking out of your ass.

HP tuners, is not backed by GM they will not support aftermarket companies other then there race teams. you give me some names of GM people that back this product. Im sure GM knows about it and says it works to a degree. but why hasnt AEM produced an EMS for the Ecotec engines? or any other company with plug and play. IT isnt that easy

the HP device is great to monitor and change a few things, but bud you got some serious issues if you think the stock engine will handle 21 psi of boost.

even with built internals 20-30psi is where you are at stock maximium you will run reliable would be into 15psi

try and go further i would love to see an Ecotec go boom

I have built more turbo motors then your girlfriend has changed your diapers. Been working with turbo cars for almost 14yrs now, you prob just got your license last year.

Twincharging your car is not the best way to go faster, single turbo will def drop a twincharge system.

I still wanna see how you bypass the GM computer and fuel system to run over 20psi of boost on a factory internals hahahaha

you show me a dyno, video and install pics then you can have my respect.

If not dont even bother replying.

 

HP Tuners is not just some programmer like the diablosport. You can write and change almost everything a Tech 2 can do. You can change literally almost any table in the ECM. You're wanting to know how we can bypass the computer to run 21psi? HP TUNERS. If you think that's impressive or somthing, we can even limit how much boost we have in 1st gear to get better 60's, and then let the full boost kick in after whatever RPM we want. You obviously have no true, extensive knowledge on what HP Tuners can do, or have ever used it. There are quite a few of us who have been running ~20psi for a while with no issues. As long as there's no KR, and the tune is safe-we've been fine so far. If you're looking for "street credit", or some type of respect from this community, you're going about the wrong way. Currently, Fast06SS has the respect, since he's going out and actually testing things, trying things, HE'S ACTIVE ON THE BOARDS, was the first to reach the 12's with not a whole lot of mods, and has been responsible for bringing us INTENSE, and the aftermarket they carry. Nobody on here is going to care what car's you've owned or built, or that you know about turbo's. You're on a supercharged cobalt board, people on here are only going to care about what you know and can do with our cars. Which, so far, the only thing I've seen is a show car. You're about the looks, to where most of us are about the 1/4 mile. I'll ask again, any dyno numbers or track times on your car?

 

u have a rhd cobalt cause its jdm tyte yo?

i dont care about design awards...iirc they arent often handed out for engineering but for show cars...how many lights and lb of fiberglass can i slap on and apply 15 coats of clear to and still be true to the STREETS lmao...i care about going fast lol

I'm 20 this is the first car im ******* with (besides my 98 neon with spray that went 14.2@101 with 75 shot and an intake) and Ill admit it...but I must be doing something right if I got my car trapping 109 with a setup thatll run someone else 700 bucks to duplicate...thats a 13mph improvement over stock

HPtuners would never be gm backed because it is capable of modifying epa emission regulated stuff and by endorsing it they would run into huge fines and penalties...how do I know...I'm an engineer...I go to the gm engineering institute..now called kettering

aem ems took 3 YEARS for the srt-4...they are the only ones that really make plug n play anything...does gm back it?

obviously hptuners is enough since it uses the computer gm uses to tune the damned car...and the gm computers...if u havent done any research...are generally more advanced than any aftermarket setup...more safety countermeasures etc.

dude im running 20-21 psi right now and have been the last 10k miles...there goes ur stock computer not handling 21 psi theory...and fyi the stock computer can read in the neighborhood of 28psi before it runs out of resolution

gfs just prevent cars from being modded

twincharging provides the desired results for the least cash outlay...and as a benefit will have better driveability with a large turbo then a none twincharged car will...maybe that is why vw just designed a new twincharged motor...efficiency and power.

do a lil research and prove me wrong I love a challenge...exactly why im doing the twincharger kit

css.net...land of the haters lol

Dan

 

desired whats up man. I used to have this magazine with your cobalt on the cover. I cant remember which one it was but your car was on the front with this sexy ass little chick was standing next to it. The write up was talking about you putting a hahns turbo in it and ****. Man your car is tyte as fuc thats for sure but there is a ? that has been burning me up. Wtf is that movie playing on your tv's in there. It was a boxing movie and it looked like mike tyson lol. Im a huge tyson fan. and cobalt fan!!

Sorry for being way off topic but i had to ask. You didnt reply last time i pm'd you about those konig rims.

 

Just to toss my word in here, I am also running ~21 PSI on stock internals for my daily driving. For only $700 too, can't beat that

 

yah within the next month or so ill be running 21PSI as well, since im uping to the stage 5 and getting a custom tune.

 

looks like the movie Ali but I may be wrong

 

prolly so cuz thats pretty much the only boxing movie i never watched. Couldnt stand the way will smith was acting ali out even in the previews. OK super off topic im shutting up.
