Turbo M42 Dyno'd (Finally) - Videos Inside

[Schnitzer318is]

Finally got it done for you guys... and for me obviously. There is more power left in it but I only had 3 runs (got 4 though) and I wasn't really tuning a whole lot during the cool downs.

Run 1 (3rd Gear Pull)



Not bad... but not great. 170.74hp and 167.86tq

Run 2 (3rd Gear Pull Added some timing above 5200rpm)



A little better... picked up some torque but left the efan on so had to redo this run. 167.92hp and 170.33tq

Run 3 (3rd Gear Pull Same as above because Efan was left on - Woops)



Still getting better... picked up both hp and torque by turning off the efan. Guess that thing really sucks some juice. 174.88hp and 173.86tq

Run 4... no video. It looks just like the others though.

Guess we should have been running in fourth gear the whole time... now I know for next time. 180.89hp and 208.41tq

There was a hiccup in this pull and I am thinking it is spark blowout. The dyno operator agreed it was probably the case. You can see it on the graph at 4550rpm.

My 3rd gear pulls peaked at a 164kpa and my 4th gear pull peaked at 168kpa. So about 9.5psi is what I am running. I posted my data long for the 4th pull below along with the dyno graph. Let me know what you guys think... suggestions, criticisms, etc. I'm just glad to have numbers on it now even though I'm sure there is more power there.

[Hey_You]

Congrats on your numbers. Get the ignition sorted out and up the boost! We want bigger/better!

[iamsam]

There has got to me more power there. 180 is a good whp number, I bet it is a quick car, but for a turbo, I know you can make more.

Nonetheless, I am sure it is an absolute blast to drive.

What is your speculation on bhp?

Me boosta :)

[ZM Blue Devil]

while the numbers are solid with room to improve... the car looks F'n fast standing still. Beautiful.

[expressfish]

awesomeness. I miss my m42. I jumped in my eta the other day to drive it up and down the block to keep the fuel fresh and I was really disappointed. No more revs !!!

How has your MPG been affected?

I can attest that this car is an absolute BLAST to drive! I believe there is def more power in there. This car gets better MPG's than mine. :( Hope that changes with Megasquirt. ;)

Good job Joe.

[Simon S]

Fuck yeah..

I'm on this forum for stats as such..

Props - and thanks for sharing..

[shEck3lls0]

This is gonna be a very similar setup to what I will be running. Thanks for the post. Car looks good too!

[Dj Buttchug]

i think you can run 12-14 easily. not sure what your afr's are tho. awesome progress non the less.

Thanks, I have plans to do headgasket and studs in the upcoming year. At that point I will feel safe upping the boost to 12 - 14psi.

I'm sure there is more power there. I have a VERY conservative ignition table. Even the dyno operator said as much while I was fooling with it. At 15% drivetrain loss... somewhere around 215bhp at the moment.

Thanks Levent... much appreciated. She takes photos/videos better than she looks in person and is in dire need of a respray. It will happen one day, but not until I can dedicate some garage space just for her. As it stands now she has 3 sisters to share the garage with.

Nothing wrong with a little eta love ;) I daily one to work. It does make this car feel like a rocket though.

How has your MPG been affected?

22mpg city and 28mpg highway... before the turbo it was 30 city and 38 highway. Still not too bad by todays standards.

Good job Joe.

Thank you sir, you've helped on it as well. LOL that clutch job was fun eh?

Fuck yeah..

No problem Simon, thanks for the kind words. I enjoy helping the forum since it has helped me so much.

Thanks... let me know if you have any questions.

12-14 psi? I wouldn't want to try it with stock head bolts. Also my tiny turbo would run out of gas pretty quickly trying to move that much air. My afr's were right where they should have been, the operator was very knowledgeable and said I did a pretty good job. He turned the smoothing off on the graphs and he said it is still pretty smooth. My problem was my ignition table... it's pretty darn conservative. How is your turbo coming?

I'm glad to finally have a dyno on the books and will update the next time I go. I have some things that need doing... motor mounts being the priority.

[Dj Buttchug]

ooo i didnt know you were on stock head bolts. i think its safe to say your car is dialed. mines ok.. still tweaking on it. i need to update my thread. I can say that its a buttpucker when my car goes on the dyno. it quite satisfying listening to it spool up after all that work though.

I feel like you could be well into the 200 hp range with studs and a fresh hg. that may require a bigger turbo though. the car sounds great. i watched the vids several times haha

[jekaio]

looks/sounds good!

my Ti would be a whole hell of a lot better with a turbo setup like this on it.
