More turbo information.
It was a pretty big project this summer, correcting a lot of DSM style little breakdowns and previous owner fuck ups as well as some of my own.
Really trying to clean the car up and make it nice again. Unfortunately I ran out of time to do the paint and body work. Got the typical severe hrysler clearcoat fade.
The basics of the setup:
94 Galant 2.4l
Stock 2g head/cams/intake
Megasquirt 2E 2.01
Stock exhaust manifold, with HMT style adapter to fit the turbo with included CDM 38mm gate
For the moment, no intercooler and 8" of 3" pipe for the exhaust
Now the interesting part, VGT turbo, Holset HE351VE from a 6.7 Cummins.
Housing variable from very small, 3-4cm^2- to very large 25cm^2
The stock actuator on the turbo is an electrically controlled actuator normally controlled by the ECM. Unfortunately I haven't figured out what kind of signal the ECM sends to the unit to position it. My experimental solution is a 14b wastegate actuator on the VGT rack arm. I didn't think it would work worth a shit, but so far its working pretty damn well.
Turbo compressor and turbine wheel dimensions.
Compressor is as close as I can measure since its a 7 bladed wheel. Measurements similar to the large 6bladed HX40.
Yes it is a 2.4l. 8-8.3:1 compression.
Here were my initial spool results with the VGT rack fully closed and fixed there. This is just the first log I opened.
Here are the the most important things affecting spool
I can't remember what gear for sure but I think its 4th.
8" of 3" pipe for an exhaust
stock head, cams, intake manifold
Fairly low timing
2600 10 psi
Its a little slower now, the actuator starts to open the thing up a little sooner than I'd like.
Keep in mind this thing has a compressor in the GT35R size class.
I'll start with turbo pictures since its out of the ordinary.
Turbine wheel and VGT vanes.
Compared to a stock 90-94 Eclipse 5spd 14b turbo also what the actuator I used came off of.
Exhaust housing compared to a BEP housing for an HX40 and my ghetto adapter.
During adapter Fab. In these the radiator top brackets aren't in so the rad sits back and makes the clearance look smaller than it really is.
