Event: Dyno Pull/road run/track run

Loaction: name of the Shop or Track

Date: 08/11/2010

 

 

Ambient Temp: in F

Elevation: Google can help you with this

Weather: Rain? Snow? clear?

 

Car: year, make and model

Tuner: Name of person and shop

Dyno Info: Mustang, dynometer, airboy, ect ect

Transmission: 5speed, 6speed, PPG, JDM, ect ect

Gear: What gear the pull was done in (2nd,3rd,4th,5th)

Peak Horse Power at RPM: The RPM that you reached max HP

Peak Torque at RPM: The RPM you reached Max TQ

Baseline hp/tq for a stock on same dyno: your model with no mods

Target Boost: In PSI

Target AFR:

SAE Correction factor:

Fuel: Octane rating if pump, octane and brand if specialty fuel

Engine/Power Modifications: Anything that adds horsepower that you have added to your car. i.e. bigger turbo, intercooler, exhaust, injectors

Driveline Modifications: Stock/Upgraded clutch, light weight flywheel, upgraded drive shaft, upgraded rear or center diff.

Suspension Modifications: struts, springs, coilovers, braces, bushings, and other items that reduce body motion and increase power transfer to the ground

Other Modifications: weight removal, addition of a roll cage, lighter wheels or rotors, smaller than OE diameter tires, and other items that affect vehicle weight, rotational inertia, and power delivered to the contact patch

Picture of Dyno Plot and AFR/Boost Plot: Ask your tuner for this or copy it from your tuning software

1st graph-original setup

2nd graph- additional mods

3rd graph- additional mods and fresh oem block.

 

Just got back from my tune at Topspeed. Thankfully i have taken all of my past subaru's there to be tuned, so i can do come head to head dyno comparison.

 

-My set up

05 LGT w/100k miles

Bnr 18g/perrin tmic/grimmspeed ebcs

stock intake with k&n

Full exhaust with high flow catted down pipe

Dw 65c fuel pump and 850cc injectors

 

-The numbers

A little disappointed in the numbers, i was expecting ~320whp and ~350wtq on this dyno.

Here you see my 21psi pump gas map and 17psi DD map. Besides the tq just being a bit shy of my expectations, it took longer in my lgt to reach peak tq then in my similar hp wrx and sti, the turbo would be fully spooled, but wouldnt hit peak tq until another 500-750 rpms later(maybe this is a lgt intake manifold thing). On the hp front, the maf was locked @ 4.6v's for about 1k rpms in the upper power band(right where the car holds 300whp), we have a good suspicion that we reached a flow bottle neck at this point limiting me to ~300whp, perhaps the oem inlet?

 

Overall the car is much faster however, i suspect it has gone from a ~102mph stage 2 car to a ~108mph car. Much more power up high, the car no longer has a tq spike and falls on its face higher in the rev range.

 

Anyways, here is a neat comparo for you to digest. My 05 sti and 02 WRX with stock motors and vf-39 on pump gas vs my 18 LGT on pump gas. 21psi for all cars. Enjoy!

Edit: RETUNED 12/23/12 after going catless w/AEM intake

Went catless and added an intake/retuned

 

310/340. Ill take it. Planning on a exhaust manifold and inlet next year.http://legacygt.com/forums/images/statusicon/wol_error.gifThis image has been resized. Click this bar to view the full image.

Retuned 3/3/14.

-Added Fast motorsport TMIC

-Perrin up pipe

-New oem block to replace cracked ringland

-Graphs you see are 18 psi safe pump map, 21 psi pump map, 21 psi 97 octane "race gas" map.

She drives great.
