Nice powerband, that motor needs to get swapped into something!

DSM...

[Halon]

Kick-ass powerband for sure.

Full boost at 3300rpm is amazing on an ef4! Can you elaborate on the dual wastegate setup you're running now?

And still on stock exhaust manifold? Awesome!

HDG6 FTW!

Also what's with the A1000 fuel pump? Stock hanger or are you running a surge tank setup?

Also y u no 3-port bcs? I love the simplicity of a MBC but going to a hybrid setup helped my top end a ton!

[Goat Blower]

Wow! Those are the kind of numbers I like these days. Looks like a sick street car!

[Constant_Project21]

Looks like that engine/turbo combo is right in the sweet spot. Damn near the same spool with tad bit more power ;). Ill have to remember to ride with you to lunch here soon haha.

That is just nasty

I believe the dual wastegate setup is simply the compgate40 external wg on their downpipe in conjunction with the internal gate on the ef4. Basically, use the internal to keep twinscroll, then let external control after wg pressure opens internal for max boost holding.

I saw the A1000 he is using, its pretty cool, wish they could get all the bugs worked out. It's a camaro fuel pump drop in hangar that they modified. Last I spoke with Chris he was going to do something like my setup, but I am sure thats last on his list of things to change at this point.

Awesome looking setup Chris!

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

[Mark Leasure]

Awesome power and turbo response for a daily car.

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.
