Title: Dyno Data (my dyno)
Post by: jakeb on May 28, 2015, 08:47:08 PM

I don't post here a ton but really should because I love the M42 and do a ton with them.

Anyway... I run a shop in Michigan and just got my dyno up and running.  Been doing some pulls with my m42 swapped 2002 and getting some data out now.

I think these numbers are pretty close but the software can be adjusted way up or down.
I wanted to post and see what the rest of the m42 guys think.

I added new electronics and data recording from performance trends.  They have a eddy brake controller too that is VERY new so still dialing that in.  But it does work.  Which is cool.

Finally getting some good data out of the machine and all I can say is it's really cool.

Some pictures...

My m42 powered 2002 on it.

This is two graphs of the same car when the engine was just warming up and then fully warmed up.

I am still learning how everything works and all the info I can get from it.

I am readying AFR from the tailpipe on this car and I think it is a bit leaner showing that what is reading happening.

Welcome back! I've been following you on the other forum(s) and bought one of your kits second-hand new, but have yet to install it. Nice to finally see some graphs and look forward to you sharing the info.

thanks!  I will be dynoing a turbo m42 in the next week or so to compare.

 THis is one of my m42 turbo kits in a 1975 2002. 

Did some pulls today...boost was a little higher than it should be so numbers are a little higher.  BUT things are looking very good.

Boost is a little high on this one so it is a little leaner than I would like.  Need to adjust the preload on the wastegate and/or richen the tune up a bit.

Your way was easier. And more powerful. Nice numbers!
