. It's called an NSG-370, and is also used in jeeps. My theory is that if it can handle the weight, and shear load of a jeep, 300 ft lb shouldn't be a problem in a crossfire. If I'm not mistaken, the classic hot rod formula is to buy the cheap model and make it faster than the top of the line model for less money.... All while using frankenstein parts and engineering skills to make something ultimately uselessly fast lol. A turbo setup making similar power to the kleeman would be safer and cheaper than the kleeman supercharger setup, as the supercharger increases the load on the engine in order to make power. If dudes in honda civics figured this stuff out years ago there's no reason we can't figure this out now
. Plus, aftermarket companies only make stuff when there is an obvious demand for a product. Turn that frown upside down fellas.. WE CAN DO THIS!
Assuming you have no problem with the ECU handling the spliced in tranny's codes and the car will start you may have something. But consider that the turbo doesn't bring on extra power or torque untill 3000 RPMs at which point the torque curve begins to flatten and soon after descend So, you are unlikely to exceed the 270 FT pounds unless you develope more than 350 HP. I know, it's just a number.
Higher RPMs generaly mean fewer foot lbs especially after about 5700 so except for redline clutch popping, you will be within the capacity of the tranny.
Our twin turbo concept suggested a 300+ HP to start with 350 likely the limit with some tuning. I believe that is relatively easy to get cobbling the right parts together.
If it is your intent to make an NA dragster, You've got to plan on more than $2K to spend. I am pushing close to 290 HP on my roadster and the rear suspension is complaining already. Our Xfires are simply not built for drag racing.
So, if it is only about HP then slap on any old turbo and make it do. But, as you have said, it is only a number. If you truly want speed off the line, I think you have much more to do to nurse that NA into the 13's
An SRT is already there.
