Attachment 34579 "7200 RPM - 0.4 bar 36 lb/min, 342 hp, "gassed out", RPM's higher than this push this turbo past it's choke line even if you run the boost at 0.0 bar (no boost at all). You're done."
I am not interested in exceeding 305 HP, so does it matter if the Garrett GTX 2867 runs out of gas?
The GTX2867 and has slightly better efficiencies than the BW EFR 7163. The Garrett GTX3071R is the only one I find that works on the low and top end and its efficiencies are not better. I don't mind that it is externally wastegated.
I'd like to see how the various turbine's area ratio (A/R) options affect the performance results.
It has come into the warm garage. There's a bit of rust on the snout but it will all be acid dipped and powder-coated before assembly starts. I will be cutting metal away, radiusing sharp corners and deburring everything first. My mock-up motor in the background is now in. Now I will come up with a basic layout for the oil cooler, intercooler and turbo. I'm hoping to make significant use of the side inlets.
Thinking oil cooler will go here. Side inlet will feed air to it. I believe I will be enlarging the side inlets. 10557649_988988577784921_2148034452603503350_o.jpg
Under mount turbo location. Exhaust will probably exit just in front of rear wheel. 1522700_988989191118193_6198347809445721454_o.jpg
Took out cross-bracing so six-speed would fit. Took out center tubes in cockpit that form a tunnel front-to-back. Will do a separate mount for the shifter. Wiring and cables may be in a tube or half-tube. Full Race headers that I am modifying for the STi hang an inch too low for the 818.
