| I give the owner credit for wanting something different and seeing it through. It always cost more, takes longer, the outcome is unknown until finished. I give even more credit to the builder for giving the customer what he asked for. I find it interesting that someone enjoys the look of this project, but if our tastes were all the same, life would be boring. The results of the project show a couple things…….
1. Single turbo set ups with large singe plenum have more lag than similar output size twin with stock plenum
2. The Z head ports and cam lift with the largest hydrollic lifter cams have more restriction than the stock plenum Here is a comparison of a similar power output 300zx twin GT35 set up with stock plenum.
This is also going through a Nissan Auto trans we built, so a stick would have higher overall power due to the loss through the auto trans running high pump pressure. This twin set up would also make more overall power on E85, it is on 116 race fuel. Even with the dis-advantages of the trans and fuel, the twin set up is making more power all the the way through, additional 100+ torque by 4000rpm that continues all the way through.
Likely the single 7175 will max out a little lower then the power level these twins are at in this chart, the twin set up is not maxed out.
