The OEM cast manifold for the LNF is not a log type acutally. It is a good flowing piece, we can use it on builds making over 400hp. It separates the runners to create a dual scroll setup for the turbo to help with spool. We have built and prototyped tubular headers that bolt in place of the stock manifold and on a stock turbo only make around 7hp more at 295hp at the wheels.
How much would a stage one kit would go for approximately?
Our stage 1 supercharger kit with the old style setup was around $3500 and ran around 6 psi non-intercooled. That was good enough to take the stock 145hp at the wheels to 195-200hp at the wheels and add around 50-60 ft/lbs of torque also. Very drivable with a linear throttle response, feels like a V6 in the Solstice/Sky's.
Excellent, can you keep me informed once it's done, i'm very interested in the turbo kit.
Fortunately turbos do naturally quiet down the exhaust since they have the turbine sitting in the exhaust stream. From what I have seen in pictures, there will still be room for a small muffler even after the turbo though. Once we get to seen one later this month I am sure all of us will have a better idea of what is going to be able to be done.
Truthfully, I don't see how. Only improvement would be acceleration above 80-90 MPH without other mods.
You will not need to go to an aftermarket ECM to limit boost on a turbo setup in lower gears. There are a couple boost controller options out there that can limit boost based on gear and also RPM. On the supercharged setups the boost is linear with the throttle response, so it is kinda built in already
