OMGHi2U Help with turbo dyno graphs

I'm in the process of making a very simple to read turbo upgrade chart for the WRX. It will look like this:

Turbo Name/Full Spool RPM/Max TQ/Max HP

What help I would like would be in the form of dyno plots. ANY dyno plots you have of ANY aftermarket turbo on a WRX would help. Specifically, I'd like the following:

Car mods list (just performance) + dyno plot

I am NOT interested in your:

Race gas plot
OMFG eleventy billion PSI, blowtorch EGT tune plot

I'm looking mostly for full TBE + aftermarket turbo plots. If you are skeerd to post, you may send me your mod list and plots to [email protected] as it's far easier for me to receive email than to surf the boards with my slow connection on this ship underway.

Don't be afraid to post if there are already posts with your turbo type. I'm looking for averages here and I am also aware of different dynos, elevations, gas types, tunes, etc. My chart will be for TREND ANALYSIS so that in general terms one can say that X turbo is generally bigger than Y turbo for those that don't want to mess with CFM data or compressor maps.

"full spool RPM" is a bit misleading. On a load holding dyno you can get any turbo to make a lot of boost really low, down low where you would only ever see it in 6th gear on the road. i.e. you can get an FPGreen to make lots of boost at 2600 RPM if you want to, it just might take a while. A more accurate figure IMHo of spool speeds would be something like "time to xx bar at xx RPM". Or, if you really want an RPM number, "RPM to reach xx bar at yy rate of acceleration starting from zz RPM". And of course, this would all have to be with equivalent flow characteristics of the other components (i.e. not FMIC vs TMIC or headers vs. non etc)...

Of course there's stock turbo love.

I know about dyno loading, that's where dynojets come in. I'll do my research to level the field as headers, FMIC, etc will play a roll.

While my chart will not be 100% perfect, you have to realize that 90% of people don't feel like learning compressor maps to find their perfect turbo. This chart is for n00bs as a general guidline vs what the more advanced user would use.

Here is my mod list (that matters):
vf34
sti pinks
walbro fuel pump
Borla header
Perrin up
Helix dp (catted)
Greddy evo2 catback
Helix tmic (which made the car amazingly consistent on the back to bak dyno runs- almost 20)
Protune (AP)
Forge bov
GPMoto shorty intake

So here are the numbers.

Cobb OTS vf34 map (91oct) ?psi
248.13whp
253.60wtq (this was only due to a boost spike at around 3700rpm)
AFR- 10.5-1

Harman 91oct - 17psi fading to 15psi at redline
265.40whp
253.41wtq
AFR- 10-1 (the key here was safety since I'll be running crappy 91oct most of the time)
This was smooth as butter

Harman 95oct (aproximate, 5gal of 101 to half tank of 91) - 18psi
290.24whp
277.43wtq
AFR- 11-1

Full boost on the dyno is seen at 3600. On the street, positive pressure is seen as early as 2200rpm (in 3+gear) and full boost is at 3400rpm.

I will dig up the dyno sheet and post it very soon.

This is exactly what I am planning on doing... I was wondering if someone had a similar setup, but with a port and polish on the turbo... I would like to regain a little of that low-end back and I have a really good turbo shop in town that can do a p&p...

I-Speed has a great database of dyno graphs that you can use. It provides the mods for the vehicles as well. Check it out:
