The current tubular manifold kit is extremely complex to install, the problem is it needs a big dollar motor to hold the power and we are in the process of bolting up
@GuruAutowerks hp28 box to it before we turn it up to avoid grenading the gearbox.
I had a big involvement in the design of this kit, its perfect makes loads of power to the point that nothing comes close to it.
This kit is built to make in excess of 1200hp and will make it, just depends if the block will hold it.
