EFR Internal Waste-Gate Discussion

[jacobcartmill]

has anyone actually put one of these on a rotary yet?

i would absolutely love to ditch my water cooled dual wastegate setup and go with an internal gate, but only if it can waste enough exhaust to allow me to run low boost (10-12psi).

i have turblown's dual wastegate manifold on my car with both wastegates recirculated, with water lines running to/between/from the wastegates back to the engine, and 7 vband connections that don't seal perfectly (yes, 7 vbands) and two air lines running to each wastegate.

i dread even thinking about removing my downpipe.

i would love to switch to this EFR turbo and run 1 air line, 1 vband, and add 2 water lines for the turbo...

John, pics as requested. Also, I have my LIM spaced out a bit, probably 1/8", because my fuel rails will press against each other if I don't. So take that into consideration. Kind of a fisheye thing going on with these pics. I had to take them with my GoPro because my iPhone is perpetually full and won't let me take pics lol.

Thanks Brian! No, I was afraid of not having enough room between the LIM and strut tower for the added space the internal WG one needs. Also, I wasn't sure if the internal gate would be big enough.

I want to reroute my wastegates into the DP, but I dread the thought of doing the work and also what it will take to remove everything. Ugh lol. I also plan to water cool my wastegates at some point as well. If someone installs an internal gate 7670 or 8374 I'll probably switch to that for the same reason.

I will say though, it's so nice blowing out someone's ear drums with my gates pointed straight at the ground when I pass them at WOT after they piss me off LOL.

Hate to be pedantic but the acronym M.A.P. is short for Manifold Absolute Pressure, I am guessing the figures spoke about here are GAUGE PRESSURE (and not) Absolute pressure, so please if we can talk in absolute units for sake of comparisons.

Turbine Inlet Absolute Pressure (T.I.A.P)
&
Intake Manifold Pressure (M.A.P)

And list it as an absolute please, as its confusing and annoying and no one has any idea if you are at seal level or in Tibet or what the actual figures are LOL.

M.A.P. is not '15psi' cause that means its like 0.3psi boost at sea level on a std'ish day lol........... and 'EMAP' that is just a stupid convict expression not meaning anything to anyone LOL.

If we insist on using gauge imperial units and at gauge readings then please use the correct references.

manifold gauge pressure = m.g.p (psi)
turbine inlet gauge pressure = t.i.g.p (psi)
and then list the ambient pressure you got those readings at

OR simply use absolute units as its much easier understand!!!! and compare.

Thanks.
