my attempt at a build thread
So i decided to rebuild my setup. Old setup has over 50k miles on it and since it was only made of regular steel to begin with, its has become a bit tired. There were a few cracks that were starting to bother me. Since i built my last setup my fabricating capabilities have changes so.. i figured i would finally apply it to my own car. With this new build i wanted to experiment with something that has been on my mind for quite some while. A "Quick Spool Valve". Basically ..My turbo is huge, and i Love the top end. Yet, i know i could really benefit from better spool. So rather than sacrifice the great top i decided to try this. To sum it all up, the valve when you first hit the gas, it will divert all the exhaust through one scroll of the turbo. This essentially changes the turbo from being a 1.32 a/r into a .66 a/r. Hopefully this mean i will get full boost sooner than 4000-4500 rpms. so.. on with the pictures.
Valve.

Very clever!!
How do you plan to control the valve?
This gives you the best of both worlds, a smaller a/r for spool up, but then opens up for better top end.
in for more results/pics

The valve will be controlled electronically using a starter style solenoid to actuate it. the solenoid will be controlled using a circuit that my electrical engineer friend is building for me. Basically using the same map sensor voltage that my engine management datalogs, at chosen points in that voltage scale it will turn on the solenoid and then at a higher voltage turn the valve off again. The kick in and kick out points will all be adjustable. This will mean while cruising the valve will be open allowing the engine to breath as well as possible in order to maximize mileage, then once i punch the throttle and manifold pressure reaches say 3 inchs vacuum, the valve will slam shut. This in order to help spool. From there once the boost reaches say 10psi, the valve will be ordered open again. The turbo is ideally spooled at this point and the engine will have no problem reaching the ultimate desired boost levels of some where in the high teens and eventually twenty's.

man, finally....a build thread from my little brother.
the pics dont do it justice, the fab. work is very impressive. the old setup turned heads for 3 years, and the new one should do that much better, while making the car an 11 second car finally

You have a car lift in your garage and you know how to weld. 
Maaaan the possibilities. That thing looks like it will be a beast. |
