Finally got my car dynoed on a Dynapack (like what MTE does for its published figures). Car set-up is equivalent to MTE's/IPD's stage 3 kit, MTE tuned.

Power numbers are 438.1 ps or 432 bhp at 5940 rpm on fly wheel which is equivalent to crank hp (not taking into account losses by the accessories).

Torque numbers are 61.2 Kg/m or 600 Nm or 442 lb/ft of torque at 4260 rpm on fly wheel / crank.

This works out to be an estimated 337 ps or 332.4 whp at 5940 rpm.

Outside Air Temps during the runs were building from 35.2 to 36.5 degC or 95.4 to 97.7 degF.

Charts are shown below:

First one shows the Boost levels achieved for the runs. For the first run, the boost sensor was tee'ed by mistake to the wastegate line instead of the boost line, but it benefitted me by showing how the TCV cannot handle the rate of boost increase (it was not laggy afterall, it just could not handle the rate of increase imo) and hence the benefit of the Manual Boost Valve "wired in parallel" for overboost control.



Second pic shows the fly wheel torque and power graphs. You can see that the first 2 runs produced the best graphs when outside air temp was showing 35.2 degC or 95.4 degF. The subsequent runs saw temps rising from 36 to 36.5 degC or 96.8 to 97.7 degF.

The combined effects of higher OAT (rise of 1.3 degC or 2.3 degF) as well as some heat soak in the FMIC resulted in a loss of about 23 bhp.

Bottom line is that a larger front bumper opening like the Evolve front bumper plus a larger FMIC is still critical in getting intake air temps down and is more an issue than say pressure loss due to a larger IC.



Third pic shows the estimated WHP, the dynapack system could not properly convert the fly wheel torque to Wheel torque as the graph (not shown here) indicated Wheel torque of 193 Kg/m or 1893Nm.

Also shown is the AFR. This is taken at the exhaust end pipes (post Cat). Could be a little too lean for tracking (but great for drag) as a failure in the Aquamist system could result in disaster.

Re: That's enough for me... MTE 432bhp, 442btq. (RainyS60R)

Thanks. I have some idling fluctuations but it could be due to some very minute vacuum hose leak or just an 04 model issue. My friend's 05 model with similar set-up does not have any problems.

Power delivery is very smooth and linear due to the turbo being correctly sized, plus MTE's programming.

Looking great Benny!

Ever considered to map spoolup and mid area down to ~1.35 bar to keep the override from jumping in? As it appears the stock boost regulation can handle up to 1.45 bar just fine.

Any drivetrain issues?

No drive train issues. Stock clutch has held up so far despite the numerous track sessions which is why I've not installed the SPEC stage 3+ clutch that I bought over a year ago.

Re: That's enough for me... MTE 432bhp, 442btq. (Johann)

http://********************/smile/emthup.gif plenty of power

How is melt control going near the turbo?


Your project has been such a great help to me and my friend. Can't thank you enough.

Thank you again

Re: That's enough for me... MTE 432bhp, 442btq. (Helmut Ranff)

Haha... I certainly hope the pics helped. I had to remove my turbo heat shield finally as it was causing my DP bolts to loosen (too much heat cycling)... since then, I've had no issues. Thinking about removing the "melt control device" now.

Very Nice http://********************/smile/emthup.gif
Perhaps when you're all done and it drives to your satisfaction you can list your engine mods (If you haven't already somewhere)

Great job! How much did you end up spending to spend to get to these numbers?
Can you get the wheels to spin (not just chirp) now or does the AWD system still keep it from lighting up the tires?

thats seems a little low for having a upgraded turbo and all not trying to bash anyone or anything, but my car on the stock turbo made only 9 less whp???

How can you compare dyno to dyno numbers on 2 different dynos when it is generally acknowledged you have to be careful of the accuracy of a single dyno....

I know all of that but still. Blot what did your car make stock or close to stock on that dyno or a dyno like that?

Try running on a dynapack yourself...
Like already noted, you cant compare this kind of dyno with, say, a dynojet which will inevitably read (a lot) higher.

I think blot may roll ~400 whp on the right dynojet in FWD mode

Not to mention he can use that power for as long a duration as he likes anyway.
thats why i asked him what his car made stock or close to stock on that kind of dyno. Trust me I know his car is very powerful that turbo he has is very good.

I think it came to about USD8K in total...


It's a bit hard to get the PS2s or A048s that I use to spin. I'm also trying to save my stock clutch, hence no clutch dumps. Based on the torque that I'm getting, I am also quite carfeful so as not to break any drive train parts.

Re: That's enough for me... MTE 432bhp, 442btq. (BOOSTED S60R)

Sorry Boosted, I never managed to get my car on a Dynapack when it was stock (only just discovered this new shop recently), but I had done some dyno runs on a 4 wheel rolling road dyno before and that yielded me 283bhp in stock form.

Like I said before, despite having a FMIC, the climate here plays a huge factor. My runs were done at 35+degC and the R just doesn't like these temps. Unless I can find someway to drastically cool the air charge, I've got to live with it.

The tuner operating the Dynapack even commented that my FMIC will only allow that much power before the dyno session and he was right....unless I use a bumper with a huge opening and hence a larger IC or cut the bumper support beam and put a thicker core IC in (not my cup of tea), plus some porting and polishing, this is about the max I will get.

The turbo is good for up to 550bhp though...but only with higher boost levels. I won't venture there (above 1.45bar) as the temps here just won't allow engine longevity imo.

You guys are lucky to have a cold season...

Boosted doesn't

However, I have the chance to have fun about 5 months a year and REAL fun about 4 (Dec-Mar) when the air temp usually is almost always under 40-44 degrees farenheit
