Here is my dyno chart showing before and after PPC. I did a power run with the PPC on first, returned ECU to factory settings, went for a 40 minute drive and returned to have the stock dyno done. The stock dyno came out within 0.4 hp of an earlier dyno I had done a few weeks back. This would suggest the PPC has an immediate effect.

So in a nutshell...

Hp Gains 145 => 176.3 = 31.3hp
Torque 176 ftlb (238 Nm) => 210 ftlb (284 Nm) = 34 ftlb (46 Nm)

The HP is about 2.3hp more than the 29 claimed by BSR. BONUS!

Torque is right on the money.

These are all at the wheel values, so it appears ALL the gains promised by BSR are delivered fully to the wheels.

If the 2.0t is putting out 175 HP at the crank (and I strongly suspect that is the case based on earlier power runs), then the 2.0t with PPC will be putting out about 206-207 HP at the crank. Add a couple for the sports filter ( I was shown some dyno charts that show this) and you are (I am) looking at about 208-209 HP. Aero territory! at a fraction of the price!

Bottom line, the BSR PPC delivers what it claims (and maybe more). Bothe the chassis and bum dyno confirm this. Excellent bang for your buck.

Very interesting Saba. Good to see the graph posted. Its nice to see that your car gained what BSR promised. Now is there an effect on the car being dynoed? Any side effects or danger?

No real danger. The car is revved to almost redline in third gear for a few seconds. Whole run takes about 30 seconds. Hand brake on, rear wheels chocked and tied down, its going no where. I was a bit hesistent initially about doing the dyno, but I was quite comfortable with the whole procedure.

Hej !

Interesting to see that stock s/w is actually slightly stronger between 1800-2400 rpm.
Compared BSR chart against your chart ?
Any corrections ? (temperature / baro / humidity)

BSR doesn't have a chart available (well I can't seem to find one anyway). Adjustments where made for atmospheric conditions. I had the stock setup done 4 times now and they all came in within 1.5 HP of each other.

Both runs above where done 40 minutes apart.

I never noticed the 1800-2400 difference. Interesting.

Thanks for posting your dyno charts. It is much appreciated by all at the forum.

Saba,

Thanks for the scientific approach to testing the PPC. I for one was comfortable with the PPC purchase for my 2003 Linear, and this is just icing on the cake. And a vendor like BSR who delivers what they say, and even more, is one that should be congratulated.

A few people have noted that turbo lag is more with the BSR. Your curves show that indeed, there could be a perception of such, as the car is indeed a bit weaker in that 2000 rpm range. I wonder why they did this ? Perceptually it makes the huge rush above 2500 even more heady. So maybe this was the reason, to make the butt dyno feel the push. Certainly Saabs don't keep their wheels planted with lots of torque in the low rpms, and they may have also decided that this was a better way to keep the wheels planted. If they increased the low end torque, the wheels would start spinning and waste all of that extra torque.

One question. Do you disable the TCS when you do the dyno run ? I would think that if you did not, you might get the torque reduction seen in the plots too ? After all the TCS has to think the fronts are slipping as the rear wheels are blocked, right ?

ESP/TCS was off. Interesting point about the "turbo lag" LinearSLT. The charts do suggest such. I think I will send this chart to BSR and see if they can comment.

Tnx for the responce, surprised that BSR doesn't hava a dyno chart. I kind of expected that...

Being honest, so far I have not driven a BSR "manipulated" SS nor have I seen the calibration data, yet.
I've heard a lot of stuff (nice and not so nice), but, you know, some people just are so full of sh-t. I'll wait for the facts.

One question about ppc sory to hijack your thread.

Is the ppc only for arc's and linear's? Or do they make one for aero's also?

· #12 · Apr 13, 2004

They do sell an Aero PPC.

Another question, for anybody that's driven a linear with the PPC and an arc/aero without the PPC, how would you compare the two?

The 2.0t with the PPC feels like it has a LOT more go in the 0-100km range. Didn't drive the Aero above 120kmh. Damn dealer sitting in the car next to me. But its been a few months since I drove an Aero, so my memory may be a bit flakey.

Thanks Stefan, but they are really just photoshop mockups of crank HP and torque and for the 1.8t (which I know is the same as the 2.0t). Do you know how the values were obtained, were they measured or derived from wheel dynos?

Saba's dyno shows that the PPC tuning gives less HP and torque than the stock software from 1800rpm to 2400rpm.
BSR's 9-3SS PPC charts start at 2500rpm. All other BSR charts I've seen start at 2000rpm. I wonder if this is a coincidence...

why would they make it worse for that rpm range? correct me if im wrong but doesnt the computer adjust boost, fuel map, and air flow for all rpm's. i know the race truck i worked on for gm we could adjust a lot of stuff (wasnt turbo though). seems like they could leave it as what it was for certain rpm and adjust it for better after that.

I think there is a degree of variation to be allowed here. Dynos are not consistent (although I did 3 runs with the PPC and 2 with stock and in all cases the PPC underperformed the stock in that range). I have sent my charts to BSR and have asked them to comment. Perhaps this is the type of changes they make with their PPC "upgrades".

Dyno chart

Hello,
I am a new member on this site. But I am a

great supporter of SAAB, have my nr. 7 now.
Anyway I follow the debate around the PPC. I used before both BSR and Nordic. On mye last car 9-3 SS 1,8 T Vector I have Hirsch step 2.The car is going very smooth no turbo lag at all.
This is the dyno chart.

I am afraid I don't know how I can do this.
Could you help, the graf is on *.doc file.
