More Dyno Charts...continuous thread...

On the next two charts whp, wheel torque, and boost are shown for all runs so it gets a little more confusing to look at, but it’s nice to see what’s going on.

If anyone is wondering whether a custom tune is worth it or not, I think these charts are pretty telling.

Glad you got the dyno :slight_smile: I will have to do some runs on that dyno to compare with the other dyno.

I’d like to see that.

I tuned Matt’s S4 on VEMS/Megasquirt Saturday. I put it up compared to an 08 STI to have some frame of reference for the numbers.

I didn’t tune the Roush. Just posting the chart…

Mike,

What kind of gains do you see with a dyno-tune on a stock 05 wrx (9-2X)?

thats my sti, thing hauls like crazy. turbo seal sucks tho :frowning: but still on stock clutch so we’ll see. thanks for the tune mike :tup: i love it

Ohh look, even this German tank makes way more power than you… If this is your way of saying I need to upgrade, nicely played :ohnoes:

HAHA

McGass I haven’t dynod a stock WRX that I’ve tuned yet since it’s only been a week, but the difference from a tune is very noticeable. I just can’t quantify it officially yet.

Steve I’m glad you like it. Thanks for coming down. :slight_smile:

EESTI I’m going to post everyone’s car compared to yours until you put a downpipe on that car. JK :wink: The tank weighs over 4000 lbs so it’s not the fastest car out, but it’s insanely smooth under all conditions so I’m very happy with how it came out. Megasquirt has come a long way.

Sweet, PM me a price for a tune and I’ll come down asap.

I’m having a low rpm hesitation issue that I’d like to get rid of before I have it tuned though. Old plugs, maybe?

Could be a combination of old plugs and the stock tunes run like crap under about 4200 RPM when in boost. In short they tried to make the fuel economy a touch better by making the car run terribly. :slight_smile:

PMing.

We’ll have to see what’s going on with this one. I’m guessing we have a boost leak to hunt down. The power oscillation that goes with the boost changes aren’t noticeable on the street, but you can see here that something is up.

wow. those numbers on the stock 08 STi are terribly sad=(

guess i need a dyno tune!

congrats. again Mike for a huge step for a great business!

Any chance of getting a stock 2.0L WRX up there as a baseline?

At some point I’m sure it will happen…

Video time:

Jason’s STI pull:

Mike’s Roush dyno drag simulation:

hey mike iank took some videos while mine was up on the dyno. would you mind if i posted them? he also took some pictures too

Sure. :slight_smile:

And this was funny. I tried to finish tuning a Supra we built on race gas. The 335 wide tires were having nothing of it. It spun so hard we got this readout:

Is that the white Supra?

Yep.
