TD04 is too small

Leafy · 02-20-2013, 11:02 AM

Car: 2006 Subaru Impreza WRX Wagon
Tuner: Me
Dyno Info: Mustang @ Enhanced Street Performance
Ambient Temp: 45*F
Elevation: about 502' ASL
Transmission: Stock 5MT
Gear: 3rd
Peak HP at RPM: 236whp @ 5650rpm
Peak Torque at RPM: 293ft/lbs @ 3000rpm
Baseline hp/tq for a stock on same dyno: forgot to ask
Target Boost: 18 PSI taper to 12 PSI
Target AFR: 11:1 on 91 octane
Fuel: 93 Octane 10% E

Mods:
Custom Tune
GodSpeed Downpipe lava wrapped
some brand of 2.5" catback
Grimmspeed 3" to 2.5" DP adapter
Grimmspeed TGV deletes
AMR inlet
Ks tech 65mm maf CAI

Yes the boost doesn't hold on the dyno like it does on the street, hence the taper to 9psi up top and not holding 18 as long as normal. And yes the afr graph is a bit weird because I was still tuning the intake in at the time. Thats fixed now as well. Theres a lot on the table still with leaning it out and adding timing, but I have a racecar this is just a daily.

Its possible they had the vehicle weight set wrong, Ive had that happen on Mustang's a couple of times. How were the AFR's compared to on the street?? Thats usually the give away the load is wrong on the car!

Leafy · 02-20-2013, 11:19 AM

They were about the same as the street, but I don't have (or even want) enough resolution in the commanded afr table to see a difference in that amount of load. I could have just dynoed in 4th to get more load, but the clutch slips in 4th.

Get a VF39, an STi intercooler/splitter and a retune.

guroove · 02-20-2013, 11:42 AM

Yup, this is what they do on a 2.5L when tuned. They hit hard at 3,000 rpm and promptly fall on their face.

Leafy · 02-20-2013, 11:43 AM

We'll see. I might build myself a rotated setup for an EFR later, but evrey time I think that I smack myself, call myself a dumbass and remind myself I have a dedicated racecar.

A bolt on stock location 35-42ish lb/min BB turbo would be kind of nice.

BlazeRex · 02-20-2013, 05:27 PM

Ha! I've heard of this car. What'd it make at 9:1 AFR?

SlverEJ20 · 02-20-2013, 05:50 PM

yup the TD04 isnt going to make any crazy type of power. I do like the tq you're seeing though. Us with the 2.0 dont get to enjoy those numbers on stock turbo

turn up the boost...let it go to 21psi

Not on the stock boost controller.

BlazeRex · 02-21-2013, 11:24 AM

Boost actually looks decent where it is now. Bumping boost won't really help you too much in the scheme of things, just puts a more of a load on an already failing clutch. I'd work on fueling, the mid-rpm rise is concerning. Also, if you are really holding 12psi to redline, thats on the high end for these cars. I usually see 9-10.

Also, was this car done opensource or cobb?

Leafy · 02-21-2013, 11:30 AM

The mid rpm rise is gone, that run was after only doing one wack at the maf tuning. Theres more power to be had pulling some more fuel and adding more spark. But with the clutch boarderline I didnt feel like running it on the dyno any more.

BlazeRex · 02-21-2013, 11:36 AM

You're making good power now. I really dont know how much safe power is left.

rideAC1 · 02-21-2013, 01:47 PM

I like the TD04 for the quick spool advantage. 293 ft-lbs tq is pretty nasty, especially that fast on the powerband. All depends on your use of the car though...as a DD it's your choice. I use mine for autocross mainly so I need the quick spool.

mod maniac · 02-21-2013, 11:32 PM

I have a fresh td04hl-19t if you want a little more.

then maybe ya need to find the broke parts and replace them and be happy with that, then

i run 21psi...have since 06 with the stock boost controller...works just fine....and it makes a difference or i wouldnt be doin it

Leafy · 02-21-2013, 11:50 PM

I know there is the space on the compressor map to do it, it may even be worth while to push it up to 23psi. But again its the daily, not the racecar.

Everyone has thier opinion on this. I would leave boost around 18-19, thats a good place to be for a daily/stock clutch. If you wanted a huge neck snapping torque spike, 21+ would help that. And it is possible to run 21 psi on a cranked up actuator.

Man these # r high as hell 18 lbs and u got 300 lbs of tq I call bull**** run that car on another dyno

You're kidding right? I know for a fact this Mustang dyno reads ~10% lower than a dynojet with the weather station on. I'll go run it on the dynojet 15 minutes from my parents house that I went to the last time I dyno'ed a car at ESP and was disappointed with the numbers. Without a doubt I could produce a dynosheet from that dynojet with 320-330 ftlbs and 260-270hp. But I dont have anything to prove to some dude on the internet, I'm not trying to sell myself as a tuner here.

wrxstage2 · 02-22-2013, 10:29 AM

I looked up some dyno sheets ur right # aren't bad it's just nuts they hit 300ftlbs I got a vf48 on a 06 tr with sti tmic, Cobb dp catless, Cobb cat back, Cobb sf intake, forge bpv, Cobb ap efi's tune nets me 284whp/334wtq love that tune but I got a Clark turner map set at 22lbs of boost I need to get dynoed cause I gotta b making well over 300 whp maybe ill try virtual dyno even though I hate those
