Default Momentum EJ5-40T tuned by PDX on WRX in TX

Another maximally satisfied TXan tuned by PDX this weekend! As mentioned by Adam and Greg, Jarrad and Tim did a remarkable job with a wide range of cars in an even wider range of mechanical condition!

The mods:

2002 WRX wagon with 22500 miles
Momentum EJ5-40T turbo
TXS TMIC
STi pink injectors
Walbro 255 pump
Perrin lightened crank pulley
Perrin panel filter (stock intake)
Scoobysport 2.5" DP
Stromung 3rd cat delete
Stromung twin tip axle back
One step colder plugs
Cobb AP - Protune!

The results:



This map is tuned to a max. of 19 lbs.
Third gear pull

Driving impressions:

Lag is about similar to stock. However, when this thing hits, it is WILD! Stage 2 was a bit more peppy in the low end, but this is SERIOUS! I am hooked! The turbo is very streetable and has great mid and top end. As others have noted before, it is noisier than some when it spools up, but to me that just adds to the fun!! I recommend it highly to all you WRX folks who want to put down some drivable big #s without breaking the stock block and tranny!

Thanks very much to Jarrad and Tim for excellent tuning, and to Brian@Momentum Turbos for letting me test this baby!

Also, many thanks due to txjunglist and metoo for organizing and running the tuning session. Three very long days, resulting in big numbers and big smiles for all!

Not trying to be an arse, but this and all the other "Texas PDX tuned" threads are worthless w/o stock baselines (sorry if they were posted already).

My impression is that while it's awesome (and what really matters to the tuning day) that the owners are happy, the dyno does read rather high.

A rumor has this dyno reading stock STi's at 270 awhp. Please understand its 3rd or 4th hand (and likely wrong) info.

A stock WRX reads about 170 on this dyno, Stock STi 250. Unfortunately hard for us to get baselines as FIS is in Dallas. We generally put our mods on THEN drive up, so its hard to have the scientific before and after as PDX often does on their home dyno.

RainMaker is right - happy customer is what counts! Absolute # is not as critical as the amount of gain (although I did want Jarrad to see if he could hit 300 whp..

270whp on this dyno for a stock sti? that's like 330bhp.

My question is, why does this dyno read high while other Mustang dyno's read low. We recently dyno tuned a EJ5-40T and it made 240 wheel horse power and 290 crank horsepower.

That is what I am thinking of having you install. I sent you a pm asking if the pinks are enough, or would it be better to go with your installing your modded oem injectors on a core exchange, along w/ a Walbro, and then doing a protune on my 02 WRX wagon.
I want to do this, but I want it right the first time. This is a 4eat tranny.
I was quoted by Import Boost on the pkg. I didn't know that you sold them.
If you want to send me a pm quote on a pkg. deal, that would be great.
TNX, Eric

you don't generally see 25 whp from a catback.
I think the dyno is reading a bit high, but I sure am happy with my tune =D. Drives like stock but hits much harder. And AdamP's car is just sick.

I would check with Jarrad at PDX. He told me that the STi injectors should be just fine. No probs so far..

wow, then Bad Dogg's car is really a beast! w/ the momentum and 2.5" exhaust he seems to be putting down what some vf30 and 3" exhaust cars do.

This turbo is a nice upgrade to the stock turbo. In comparison to the VF34, VF30, and VF22 it is quite small, but does offer faster spool characteristics where as the bigger VF series turbo's will make more top end power.
Ispeed is saying pretty much the opposite of what momentum says about their 40t.

With my tune, I am able to hold boost till redline much better than a 30 or 34. Also I am putting out 20-30 more peak HP, with good torque. The turbos look to be of similar external size, don't know the details there. Perhaps the difference can be accounted for by different tuning styles?

They can say all they want, but tons of graphs here have proven otherwise. The 40T holds WAY more boost to redline and makes more power, and sooner in many cases as well.

Steve told me that they very rarely make over 260, with most STi's being in the 250's.

That car was bought used by the present owner and he later said that he wasn't sure what all had been done to it. I would not use that as any type of baseline. Steve and Rick both said the baselines for the dyno are 170 for a stock 2.0L WRX and 250 for a stock STI.
