Good Stuff. That's personally one of my favorite tube style manifolds, i have a image someone made on 2gnt a long time ago that's identical to yours. Just a few questions: What type of turbo? Was 400hp made on race or pump gas? What type of engine management? Keep us updated on the new power numbers/build. :thumb:
 
yea this is a copy of one that xtreamfabricatons builds, the car is running a gt3076r and is on e85 using m400 motec standalone. the car made 345hp at 20psi on 93oct using nitrous grind comp cams, it made 260hp at 15psi on 93oct also. at 20psi on e85 power jumped to 400hp and at 15psi it was over 300hp. the car was built about 8years ago and has only had a turbo upgrade, it was time for a new set-up so it got broken down and building it up for more power.
