Building my dream M3

[thedude60126]

too bad it wasn't done on the same dyno.

Agreed other dyno was not going to be available for a couple months good news though that was a dyno jet and this was a mustang dyno so number would actually probably have been higher

That it was. It’s replacement is a bit better.

Agreed man beautiful bbk is my next upgrade for my car for sure.

awesome build, wow cant believe there is a kit to do ITBs that is so cool to see.

Never would have thought I’d go fix back but it’s super comfortable and super low seating means helmet fits great

How did you bolt down the plates with that HVAC vent?...i have similar plates for my car...but when i saw that and tried to install i thought it would smash the vent...any help would be greatly appreciated!!!

Seriously considering those ITBs.

Obviously a portion of your gain was a slightly higher redline. But you're also making power ALL THE WAY to that higher redline, too, compared to it dropping off WELL before redline in the prior graph.

I see the "before" line on the new dyno graph - where did that come from? Did you manually load that in from the previous run for comparison?

And given that first one was a dyno jet and this one AFTER the ITBs was a mustang, does it feel like that's accurate? Or does your butt dyno tell you it's ALL upside?

I occasionally track my car, but 99% of my driving is on the street. It's my daily, so not committed to this if it'll hurt torque significantly on the low end. But I can see lots of reasons that "comparison" line might not reflect reality.

Cool! Looks awesome.

So... I just lost a timing chain guide on Sunday. Given you must remove the head to replace them, and given my current mileage (and the beginning of some indicators confirming the bottom end is tired), a full rebuild is in order.

I've ALWAYS thought I'd go to 11.5:1 when that happened, and given the results with this build I'm encouraged.

And so suddenly a little feedback on how this thing is holding up and is to drive around town is more important than a month ago when I was just mildly interested.

Back in the day there was a local who did basically what you’ve been thinking about, and I believe he was very happy with it. Owned it for years , and most likely still does.

I’ll ding up that dyno sheet, and post it here .
