evo 9 hillclimb build log
Oh yeah. Compound turbos setup baby! Haha
The 3582 is for pikes. We really debated going with the 3584 but wanted to keep as much bottom end as possible. Hopefully the 3582 is the ticket.
The other one is a 3076 to use at the lower elevation races if we want a quicker spool. We were at 480whp (mustang Dyno) last season and it felt sufficient for most of the hills we raced at and the 3076 should be good for that plus a little more. With that said if the 3582 has good bottom end we'll leave it on.

we had a 7163.
it seemed alright but i wasnt overly impressed with it. talking to a few reputable builders/racers over the winter all signs kept pointing to garrett.
if we were not going for more power or staying at a lower elevation the efr would have worked alright but going bigger the next size up (8374??) didnt inspire confidence.

one very knowledgeable tuner logged boost and back pressure. he quit turning it up when the pr was around 2.0. he was at 513whp on a mustang. we were ar 483 on a mustang so i would say we were arguably at the limit of the turbo. the power was alright but we wanted a bit more. if we took that turbo to pikes we'd either have to drop the power considerably or run the turbo beyond the critical wheel speed and dnf.
as far as spool it wasn't anything to write home about. part of that was probably in our setup as we had an undiscovered boost leak issue during one tuning sessions but even after that was remedied i still wasn't impressed.
as far as cost its not much different that a gtx.
wanted to get a solid mounting point for the front end. the stock areas flexed and that was causing the splitter to have unnecessary movement.
ended up on this design.
.135" MS inner and outer plate. This allowed for welding on the flats of the frame not just the end.

dry fit:

welded up. my cousin is out of town so i had to do it. they should hold but not nearly as pretty

my one good looking weld

The fellas have been busy the last few days. Couple pics on some areas.
Start of the new front end

Top bar in ans welded up. IC just hanging out there. Not its final location.

This was a tricky fella. Trying to get everything sorted for the rear radiator. Turned out sweet! Hoping it works well.

New Giro disc X rotors with the fortune auto two ways. Excited to try the new setup out.
