Default TopSpeed built 2011 WRX | Dom 1.5XTR E85: 510whp/512wtq

Car: 2011 WRX
Location: TopSpeed Motorsports, Alpharetta GA
Tuner: [email protected]
Dyno: Dynojet linked AWD
Transmission: 5 speed
Gear: 3rd
Peak hp at rpm: 510whp @ 5,770 rpm
Peak tq at rpm: 512wtq @ 4,800 rpm
Target boost: 24 psi
Fuel: E85

This car belongs to a good friend and customer of ours who primarily road races the car. We recently had it in for some slight suspension/steering upgrades to prepare for the rest of the 2016 racing season, and while it was in we strapped it back onto the dyno for me to make sure everything was looking good, and just to make some adjustments.

His setup is:

TSM shortblock
GSC S1 cams
Perrin FMIC
Tomei equal length header
3" downpipe
3" catback
Intake
ID1000cc injectors w/485 pump & TSM fuel system
PPG gears
E85

Tuned on a Cobb AP

I first worked on the road race map, which on a very conservative 20.5 psi made 410whp/384wtq. Very manageable and reliable for long track days. I then turned it up a bit and on 23 lbs for his "street map" it made 457whp/446wtq. Still plenty reliable and still stayed pretty conservative, as this car just wanted to pick up power very efficiently.

I then wanted to pull out all the stops and have some fun Since this car has my favorite setup (FMIC and EL header....efficiency!) I knew it was going to continue to pick up power...I just didn't think it would make this power on such low boost. I turned it up slightly and worked on a few different aspects in the map and stopped at just over 24 lbs of boost.

24.28 psi - 510whp/512wtq

I believe that is the record for a Dom 1.5 on an EJ, which I think we previously held at 504whp/522wtq on another build we completed a few months back that I posted.

We then put the car back on the road race map and he took it to the track and raced it all weekend long.

Just wanted to post this up!



Comparison of all 3 maps

Serious power for such a small/simple setup.
What's the fuel system consist of?
I've not seen many id1k e85 cars running over 500whp

I've put many FWD cars on ID1k's over 500whp, but was surprised this Subaru made it that far. It definitely doesn't have any headroom on the high map though!

It has a Walbro 485 (high pressure) fuel pump, with the 12V rewire, lines, rails, FPR, and a base fuel pressure of 55-60 psi.

I have an 04 STi with a Dominator 3, and about the same setup (ID1k, 55-60PSI base, WB485, hardwire, etc). I have stock cams and a Spearco TMIC though, and am hitting about 450WHP on a Mustang Dyno here in Chattanooga. I wonder how much is the S1 cams help, and FMIC, and how much is car / tuner, and how much is dyno differences? I am looking as ID1700 injectors for the future, as I run E85 only as long as I can get it.

Very impressive! And just another reason why my Forester with a 1.5xtr and built ej255 will be coming to you guys within the year!

It's really tough to say exactly what you get out of the cams because there hasn't been a great back to back done (or at least we have never done it) and most cars have several differences in the setup that make it hard to compare accurately. Based on what we've seen, the S2s would probably be a little better of a fit and will simply help the car make a little more up top and shift the whole power band to the right a little - the other benefit is you'd be able to rev it higher with the upgraded springs too.

Probably the largest upgrade you could make is switching to a FMIC; I would say that's going to help more than the cams and it will be less expensive to do it. ID1700s would be over kill and you would give up some low throttle drive ability; the ID1300s would be all you need for that setup.

It's tough to compare Dyno Jets with Mustang Dynos simply because Mustang dynos are able to be adjusted by the user and can have huge swings in what they read whereas the Dyno Jets are pre-programed from Dyno Jet with no user input adjustments.

You're only about an hour and a half from us, if you'd ever like to put your car on our dyno to see how it compares we'd be happy to do it - let us know if we can ever help you.

Is it just me or is the spool a little slow on this setup, particularly for E85? I would have expected torque to come on sharper. Is that intentional, or due to this particular setup (FMIC+cams)?

I'm asking because I have a Dom2.5 XTR on my Street Mod autocross car and I need to switch to a FMIC, but I don't want to introduce too much more lag.

Look at the comparison graph to get a better understanding of what is going on. The blue line is the 20 psi graph, and you can see it hits full boost right after 3600 rpms. On the higher boost map it hits full boost a bit later since it'll take a slight bit longer to reach the extra 4 lbs of boost while it is already making 400+ ft lbs by 3900 rpms, so the car is just accelerating that hard and already carrying it through the rpms. On the street you will see all this happen about 200 rpms earlier, and a 4th gear pull would bring it in sooner too I suppose as there would be more load. Just remember, smooth is fast. A violent torque spike is cool to brag about, but it doesn't make the car any faster.

In all honesty, a FMIC will introduce a little bit of lag, but it is hardly noticeable in real world conditions, and the benefits definitely outweigh the sight response time difference.

Thanks for the response. I don't want a violent torque curve, and your dyno plot is definitely very smooth, so it wasn't intended as a knock in any sense- just was curious about the responsiveness of this setup.

"Smooth is fast" is one area of my driving that needs work

I didn't take it as a knock against anything, just wanted to better explain it is all!

I'm pretty sure I could use some driving work in that same department

Do you have any plans to get JRtuned scheduled for this summer? I may try to get in if so. I love having a TMIC, so am willing to take a hit on power for it. This is a daily driver, and honestly more than enough. My tuner had done an amazing job. At some point I would like to go ID1300 (he and you have both said the same thing about the 1700 injectors) and Speed Density. It would be nice to have JRtuned do the SD tune.

We have no current plans to have JRtuned come down and tune as we have an in house tuner; his name is Taylor.

Have a look at some of his handy work here:

Cool.
Did you hard wire the pump?
What was your fuel pressure at?

What fuel pressure regulator, what sized lines, which part number Walbro pump, what is your base pressure, how well does it hold fuel pressure at WOT, and what is the wiring setup on the pump? Just a pump and these injectors will barely get you to 400whp...theres more pieces to the puzzle than that.

Thanks for taking no offense. People should understand that on a Subaru, on E85, they'll generally run out of injector around 380-400whp with ID1000's at 3 bar fuel pressure. I became a professor on fueling by dealing with lots of problems. Yes it is possible supply a ID1000's at 100psi base fuel pressure in a setup running about 30psi boost. This would make 500-550whp on a Subaru on E85. If you remove the teflon lines (means no absorption of pulsing)you will see a massive reduction in the pulsing results a step reduction in injector flow at resonant frequencies and add more room. Of course running too much fuel pressure brings different problems but thats another story.

So i was trying to say is yes it is very possible to max out id1000 at 1 bar of boost with GT30 or make 550whp+ like TopSpeed did. It is whole fueling setup that brings that power(even every oxygens molecules in the air).

As he states, on my daily drive spec c car I can only make 411 whp @43 psi with a hard wired genuine Walbro 465, [email protected] psi.
