Turbo M42 Dyno'd (Finally) - Videos Inside

[Ryann]

Awesome man! My interest in adding boost is peaked.

thanks for the M42 porn. Get the timing unconservative and post more. I'd love to see a boost/tach video to show how quickly the turbo is spooling ;) what snail are you running anyway?

Thanks guys... it's a labor of love, and sometimes hate.

If you look at the graph of my log you can see the spool time by watching the map sensor climb to max boost versus the RPM it's at. Somewhere around 3500-3800rpm I would guess. Could check my log and get exact rpm...

Turbo is a TD05-12A off a Mitsu Starion. It's a tiny little thing which is what I wanted. Boosting earlier was better than max HP in my eyes.

You should get a 16g instead. Tuning should def help the spool time. You should be seeing boost earlier me thinks.

^16g compressor wheel and inlet housing? Or the whole turbo?

Something like this? Though honestly if I changed turbos I would want to change to something that is externally gated. My internal and wastegate actuator are a constant cause of frustration

The whole thing is pretty efficient, but I think the compressor side is more efficient. IIRC the compressor is also what makes it a 16G vs your current 12A. BTW, I'll be in SA next April 8) Will you still be there?

^Yep, I'll be here, don't travel too much... but occasionally. Going to take her off the road for a head gasket, motor mounts, high impedance injectors, and some other mods/maintenance in the near future... sounds like a good time to get the new compressor turbine and housing.

Very cool, nice work. The car looks good too

Cool, maybe we'll be able to meet up and swap M42 stories :)

[Schnitzer318is]

Woah... yes that would be cool. I wouldn't mind picking your brain about your build. Very nice btw.

[bwawuz02]

Thanks! I wouldn't mind throwing a turbo in the mix a little later down the road too ;)

Looks like you'll need the whole center section/compressor housing and possibly bore the turbine housing 1mm to swap over to a 16g btw: http://www.starquestclub.com/forum/i...post&p=1243230
