Thumbs up prodrive Power Pack - Stage 3

The mechanical pieces of the kit are beautiful. The downpipe is an awesome divorced wastegate design. All of the pieces bolt up perfectly. The up pipe has a flex joint - meaning that it will be virtually leak-proof. The only problem I had with the mechanical pices was that there were no studs in the up pipe. However, prodrive shipped me some overnight.

The muffler sounds awesome. Not too loud, not too quiet. Just right. There is a black coating on the inside of the muffler that seemed to bubble up and flake off a bit. Don't know why or how this happened, it looks not-so-good, but is not very noticeable at all.


DOWNPIPE


UP PIPE


INSTALL

Not something you want to do you first time out, but everything should be doable by a novice except the up pipe.

-----------------------------------------------------------------------------------

Next, some number that were requested.

I see about 19 psi in all gears.

50mph-70mph acceleration

3rd=3.2 sec
4th=4.6 sec
5th=9.2 sec

Conditions: flat straightaway, ~65 degrees, 100lb. passenger, 3/4 tank of fuel. Taken with a stopwatch.

These numbers seem to be on par, and I am very satisfied with them. I will state that I don't think that the 50-70 is too good for you engine in 5th. It bogs big time. However, you will no longer have to downshift at 70 mph in 5th gear to pass...just hit the gas.

------------------------------------------------------------------------------------

How the PPP3 performed on "The Tail of the Dragon"

Simply put, I can now take corners in third gear that I used to have to downshift into second for. Of course, it would probably be ideal to shift to 2nd, but it isn't necessary on most corners. As I stated before, in gears 1-4 the power is almost ALWAYS there. My turbo begins to spool at ~1900 rpm in every gear. There is no bogging out in 2nd AT ALL. I have seen the dyno plots for the stage three and boost isn't full until ~3500RPM. Prodrive must have made the down low power with fuel and timing.

I have NOT noticed the power loss that people have reported with the PPP2 after 5500RPM. I have smooth, instant power. I love shifting out of 2nd and into 3rd. 3rd gear feels very very good. You just want it to go on forever....but then you shift to fourth

Unfortunately (for some of you), I don't drag race. I don't know how the PPP3 would fare on the strip, except that you should beat a stock WRX rather handily, especially after you get to 3rd gear.

I would recommend the prodrive pack over any other tuner, because prodrive knows the impreza. They have been working on them since it was born. If nothing else, my mind is at ease because these are under warranty in the UK. They wouldn't be under warranty if they weren't safe. Hopefully, they will be warrantied and a dealer option here soon, but don't hold your breath.

That's about all I can think of right now.

Oh yeah.....

SRT-4 is no longer fastAr

Great review! What class does the PPP3 put you in? (along with the other mods you may have?) I'm assuming STX, but that might be nice clarification for anybody else looking into the PPP3. Those times look great, and you're one lucky guy to be able to use the "dragon" for a testing ground!

Guys, I would write a long review of how it performed on the autocross track, but just refer to the one above, because it was just awesome, even around the tightest turns - no bog in 2nd gear.

the drawback of the PPP (any stage) is that it puts you in SM (because of ecu reflash), so to be competitive there, you really need more modifications (i.e. suspension). I have prodrive springs and a cusco rear sway, but coilovers would be NICE. I was ~2 sec off tthe SM leader.

However, I did beat a lot of people that I don't usually beat.

I have boost numbers now, post edited above.

Thanks for the excellent review.

I do have a few quick questions:

Have you had any problems with your CEL staying on, or does the ProDrive ECU re-flash fix that?

Have you tried to pass emissions with the Stage 3 PPP installed? Just curious if it's smog-legal in all 50 states.

Noticed any difference with your gas mileage?

Thanks -

smiliar question, PPP3 removes all three stock cats correct but it replaces 1 of the cats, the downpipe onewith a high-flow cat?

Too some people this might sound silly but I would feel pretty bad running my car without any cats, not to enviro friendly. Just checking to see that PPP3 runs 1 cat.

1 hi-flow cat in the downpipe (note the "diaper" that is heat coating to keep it nice and warm)

No CEL's - the Prodrive ECU tweaks a stock ECU using ECUTek (Prodrive's "version" of it.)

I don't really have any accurate gas milage figures as I have been "on it" constantly.

I'll track it in a couple of weeks

No CEL at all.

However, there is no EGT bung in up pipe, so i would assume that you would get one from that, but I already have done teh resistor mod.

We don't do emissions here so I won't have to worry

Hi Guys

The EGT is moved from the up-pipe to the down-pipe, to avoid problems with it breaking off and going through the turbo

The is a high flow cat in the down-pipe, this cat meets UK emmision requirement and indeed has been tested to continue to meet them for 3 years / 60,000 miles (this is the UK warranty period)

The CEL should not come on for cat efficiency

"Diaper" hmmmm well we call it a sock, it's achualy there to protect the engine bay items from the heat of the cat, much like the turbo heat shields.

Cheers

Why are so many people using a stopwatch? Isn't the PPP based on ECUTEK's DeltaECU which comes with their DeltaDash. I would think it would be far more accurate to simply log MPH vs time on the DeltaDash.

Link to general AccessPORT info thread on NASIOC

STX legal maps (and all maps) will be available from Cobb and others free of charge once this releases. Users can switch between 10 custom maps on-the-fly (engine off, i think).

sorry i took off after the last race. i didn't realize dinner was waiting on me. it's nice when they tell you these things as you're about to drive a PPP3-modded WRX

honestly I have not noticed a difference with MPG. others have said that they have seen an INCREASE in their gas mileage. Apparently the stage two hurts MPG, whereas stage three helps....

Simon, is it possible to switch between the stage 2 and stage 3 maps once you have purchased the ppp-3? Also, do you reccomend using new exhaust gaskets or reusing the old ones once you install all the pieces that come with the ppp-3 kit? This kit is for 91-octane gas right?
thanks

Just buy new gaskets for both end of the up pipe. The rest you can re-use. Squirt the donut gasket down with some lubricant and pry it off of the stock mid pipe.

And, no I don't think it is possible to switch to stg 2 from stg 3. I think that Daddy's SCP (a vendor of PPPs) puts the stock map and the stg 3 map in the ECU so that you can swith between those, however.

The only Prodrive flash we put on is the Prodrive supplied map. We have no ability (nor would we if we did) to change any of Prodrives map settings. Being EcuTek based Map switching is supported but for base map and performance map, no switching between one Prodrive stage to another.

Hi

You don't, there is one calibration in the ECU, the PPP3 one.

Simon,

That wrap that is over the cat - is it a type of fiberglass based material?

I sent you an email but haven't gotten an answer.
