MAP's 2008 Evolution X GSR Build Thread aka Project GGX

Pretty badass build! May I ask why you're using FIC injectors rather than your own? any plans to add a ported throttle body?

Been running these since before our injectors, FIC has always had our back in regards to projects and race cars, great company. Throttle body would be an interesting before and after! lol

It would interesting to see dyno sheet over lay of this car and murlos car. you guys are close in power.

Like Murlo said, straight boost source to internal to preserve spool (nearly 1000 rpms lost with only external) and boost control to the external gate. Also as stated, drop in Camaro pump modified for Evo X tank, still has fuel level issues to sort out. Also, I do still have the stock EBCS in line, just haven't gotten a chance to dabble with dual boost controllers however it isn't dropping off too bad.

LOL thats the goodiest shit ive ever heard of! I love it!

I say go back to just internal gate.

[Kracka]

Boost control sounds way more complicated than it needs to be :lol: Two wastegates and three boost controllers (1 MBC & 2 electronic solenoids)...

I would like to see how just an internal Turbosmart WGA with a Grimspeed 3-port BCS does.

[v8klla]

Yea it is a bit of a headache lol, but internal with MBC should perform similarly.

Great powerband Chris.
Excellent work MAP crew.

Well although it may be overcomplicated, the boost control works. I think straight 3port (or 4 port) is the way to go, but I don't think the dual wastegates is a bad idea, I have seen that make more power over just internal. It overspins the turbo yes, but if you want max power, do it.

I tried using fotoflexer to overlay mine from the dynoday and chris's 4th gear pull. Fotoflexer wasn't working...I was going to post in my thread as to not clog this up. I guess if someone is feeling bored by all means do the overlay. Maybe overlay mine, scheides and chris's for 2.0l vs 2.2 vs 2.4 (really 2.5 I think). Might be really clogged though with all the dynoday runs, would be better to do it at MAP on their comp.

MAP needs the same online dyno database that Cobb has.

How do the 2 WG's overspin the turbo? Because it's holding more psi?

Yup, higher boost in the higher RPM's.
