Evo X upgrades - Page 2

**mlomker** · 10-08-2009

I underestimated how long my visit at DB would be, but I think the results speak for themselves.

I arrived at 10a and Shane and Brian went to work installing the AMS fuel rail, Perrin 3-port, and DW800 injectors. That took until about 11:40. Strapping the car onto the Dyno required pulling part of the undertray so it was a little more time consuming than the routine at MAP.

Shane had finished dialing the fuel in and suddenly the AFRs went to 16. Shane and Brian spent the better part of 45 mins experimenting with the tailpipe o2 sensor and finally Shane threw in the towel and suggested plugging it into the rear o2 bung. When he looked under the car he discovered that the midpipe had disconnected behind the cat! In retrospect I should have known something was wrong because the car was sounding mean, I saw smoke in the wheel well, and my eyes were stinging from the exhaust. Silly me...the Specialty-X exhaust didn't come with lock washers so I didn't install any. One of the guys (John?) installed a new gasket and bolts for me (after backing the car down the dyno ramps a bit for access).

It's still a little early but my immediate impressions are that the car makes a MUCH smoother transition from no boost to boost. The Perrin 3-port is also crazy-loud. You never hear the stock boost-control solenoid but this one makes a constant clicking sound...was a bit alarming until I found the source of the sound.

Awesome! Do you have a before/after overlay? That is a *very* healthy hike in power/torque! Have fun with it!

Very healthy hike indeed, I'm very impressed with the before and after tune numbers. One sick X my friend.

Not sure how accurate Shane's shootout mode is to MAP's dyno, but the guys that have done pulls on both say it is pretty close. 281 -> 357 on a Dynojet is quite a bump in power.

What I like the most is the smoothness when making a pull. The car surges if I try to cruise in the 2-3k rpm range but I should just stop being lazy and downshift...the stock tune did that once in a while as well but it's consistent now.

**mlomker** · 10-08-2009

No, we didn't do a pull before the new parts were installed. The initial pull after installing larger injectors and 3-port was nasty...under 200hp. Took a couple pulls to dial in the fuel.

**goodhart** · 10-09-2009

The stock BCS on Subarus do the same thing, making that clicking noise all the time.

Nice numbers!

**scheides** · 10-09-2009

Where did you mount then new BCS? Sometimes the 3-ports can make noise like that when mounted directly to the frame. Get a rubber or silicone gromet (or make one) and put that inbetween the BCS and the frame, should quiet it down quite a bit.

Thanks for the ideas. I had Shane install it and haven't taken the time to admire his work yet.

I bought a turbo blanket and am going to trim back the stock heat shield to try to cure the vibration against the downpipe. I'll take a peek at it while I'm working back there.

I'm thinking about having DB do the install of my suspension upgrades in early Nov (when I get back from vacation). Nice looking shop and a good group of guys there.

Trimmed my heat shield and bent it out to eliminate the vibration.

The 3-port install looks very professional, as you'd expect. Shane put it right where the stock solenoid was, reusing the bracket. The difference is that the stocker vented into the turbo inlet and Shane plugged that hole and the 3-port is now venting to atmosphere.

I've decided that I like the noise...just another touch of mean. I had some teenagers at the gas station rubbernecking today. Must admit, I like that now and then...makes the effort feel worthwhile.

Sweeet numbers!!

TkrPerformance · 10-09-2009

good numbers. shane all ways goes way beond to help everyone out

What was your boost at for the 357 run?

Same, That was shootout mode. Used to compare with DynoJet numbers.

Based on some posts the other day, they are awful close to predicting the number on MAP's dyno.

Shane went for 25psi as flat as he could across the midrange and then the stock turbo loses its breath up top.

Forced Fed · 10-10-2009

The power difference between MAP's dyno and DB's dyno is probably around 12-16%. So to go from 281whp to 340whp/352whp is at least a 60hp gain just from a tune.

Money well spent.

Edit - 27lbs of boost at 3,100 RPM also has to be fun, probably around 2,800 RPM on the street!

haha. She feels really good from there on up. Shawn's X did 340 on MAP's dyno so I wouldn't be surprised if mine was at the same level.

Forced Fed · 10-10-2009

Get some more pics up of the set up yo!

**mlomker** · 12-07-2009

Shane threw in a set of DW1000's and re-tuned me on E85 (E70 pretending to be E85, anyway).

I had him not get too wild with the psi. The stock X turbo can spike into the 30's but what I've been told is that it impacts torque and not hp since the boost tapers badly beyond 5500. I just didn't see the point in abusing the stock clutch like that.

I threw on a set of Icebears this afternoon for the winter fun.

On 12/12 I'm installing the rear anti-swaybar and a TWM short-shift kit. After that is the KW V3 coilovers and a Whiteline roll center kit install. A BBK, gauges, RE30's/NT05's, and some carbon aero is planned for the Spring. I intend to have this car complete by the next Mitsu cookout!

Bump for an old friend still providing valuable data even after he's gone! Miss you bro!

**goodhart** · 12-07-2009

Wow, nice numbers!

This is just from switching to E-85?
