Hahn Racecraft Cobalt SS 2.4 Turbo Prototype!

Turbocharger as viewed from top
Here you can see the Super 20G turbo, tucked in close to the engine for maximum response and best heat transfer. There is a heat shield above the turbo that's been removed for this view. The wastegate actuator features an easily-adjustable turnbuckle to fine-tune boost level.

Undercar view
Here you can see the turbocharger from underneath, as well as the downpipe flex-section. We replace the stock catalytic converter and pipe, for they are not up to the airflow of the turbocharged engine.
#104
Last view: downpipe
The downpipe continues rearward to hook up with the cat-back exhaust. It's a 2.5" diameter. There's no cat on this car, but in production, we will offer cat options.
That's the last photo for now. Thanks!

2 questions:
1. With the intercooler to throttle body duct located in the right front fender well, is there any room left there for the inlet air filter to be run to the same location so it can recieve cooler air then the present location of under the hood?
2. I see the oil supply and return lines for the turbo in your under side picture. Does this set up use the additional water cooling as well? If not, can it?
Separately, about the auto/manual trans issue...
My goal with this car was to build a daily driver that produced the most horsepower possible in the most reliable fashion possible. I bought an auto specifically for two reasons. The first was as a daily driver, an auto is quite frankly easier. Second, most drag cars are in fact automatics. With the current abilities to tune the 4T45E trans, it can be a great drag car as well as a driver.

We've done a number of systems with similar underhood air filters, and with effective intercooling, all has been well at these power levels. Available underhood space is at a premium on these cars, so component placement becomes a dance of deciding which areas can be compromised, and which cannot. Free-flowing piping runs that are minimally intrusive to surrounding components are the biggest priority, and thus the overriding challenge.
We don't have watercooling on this particular system, but it could be readily retrofitted...the turbocharger does have accomodations for it, and we have fittings and related parts to make it rather straightforward.
You are right on about the advantages of the automatic! As technology availability continues to improve, it's ever-more viable.

I'm 54. Look at my car. It ain't stock. A LOT of "older people" were building performance before most of you were born, and are still interested. Some of us even made the leap to modern technology rather than V-8's and Holleys
I also know a lot of "girls" that like to build cars.
Now, how many out there will have the bucks to buy a turbo kit, I don't know. I, for one, would prefer a turbo/automatic set-up, because they're much more consistent running brackets (take a look at the number of drag cars with autos - there's a reason, and it ain't total performance).
#115
Looking at the pictures, if we say had or wanted a strut bar, would that effect if it will fit or not, because looking at where my strut bar is i think that would be a tight fit, but i also have an auto so the kit might be slightly reworked i think...correct me if im wrong

Bill....Ok, I see the intake pipe, and the post intercooler pipe to the TB.
Where does the charge pipe run from the turbo to the intercooler? Also where is the bypass valve?
Bill I assume it works ok but how come you are running the MAF on the charge pipe right before the TB? Wouldn't/couldn't you run the MAF right above the intake cone filter pre-turbo and the bypass valve post turbo?
I am assuming they are there I just can't see them...Otherwise...thanks for bringing reality to our little corner of the world..we have BOOST.!

Good question about the MAF sensor though. Dan and I were planning on putting that where you mentioned... before the turbo. Bypass valve is another good point... I didn't see it in the pics. It has to be after the turbo... but I don't see it.

You can purchase directly from us, or from one of our dealers.
Pricing will be determined soon...we have to finish development before we can accurately cost it out.

We've done a fair bit of experimentation, and the MAF functions best in the location shown
You're welcome! Thanks for your interest. We're looking forward to these getting out there!

lookin good and the pics are great....im sure that we could probably find somewhere to run that intake outside of the engine bay.....and guys the maf is in side the intercooler to tb pipe....maybe its a better idea cuz the air is cooler and maybe it would be more efficient and fuel productive to put it in the intercooler to t/b pipe....wouldt you guys say the same
