TRD 5.7L Supercharger - Dyno Test & Tune

THUNDERA · #1 (**permalink**) 05-17-2009, 01:23 PM

Just thought I'd share the results of my recent day on the dyno over at MAC Autosport in Parker, CO. See charts below:

Baseline Run: 3/18/09 - Factory intake, JBA headers, TRD Exhaust - 293 RWHP; 324 RWFTLBS (Corrected)

Baseline Run Before Tune: 5/15/09 - TRD Supercharger, JBA headers, TRD Exhaust, URD MAF Calibrator (empty map) - 441 RWHP; 469 RWFTLBS (Corrected)

Final Tune: 5/15/09 - TRD Supercharger, JBA headers, TRD Exhaust, URD MAF Calibrator (tuned map - 10.5-11:1 AFR) - 466 RWHP; 501 RWFTLBS (Corrected). With 20% Driveline loss this is 583 HP/627 ft-lbs at the crank (Corrected of course)

That's right folks - The TRD supercharger with tune netted me 173 HP and 177 ft-lbs gain AT THE WHEELS on a measured 5 psig of boost!!! The main reason the gain is so large is because up here at 5500-6000 ft altitude forced induction loses less power than naturally aspirated vehicles - hence the advantage of owning FI vehicles in Colorado

Enjoy!

Are those temperature numbers accurate??!?! 82F during the pull?

Should be pretty close. It was about 75 outside and sunny. The dyno is right inside the garage door and the shop was definitely warmer than outside just due to all the pulls we had done...

Very noticible change in power when it is cooler out. It got down into the 50's that night and it pulled like crazy. I continue to be blown away by the power of this thing.

Awesome man!!! Thanks for sharing that? Any video? One day I will get me a supercharger. One day!

Any plans on changing out the fuel pump for a high flow fuel pump? I see where some have done this, after putting the supercharger on.

Those are awesome numbers, esp. in that heat & at the rear wheels...I'm truly impressed!! Brad

URD MAF calibrator and a dyno tune. I always suspected history would repeat itself.

Brother, after you get your fill of 12 second passes

did you ever do any tuning on the NA engine, or just on the charger?

Quite impressive numbers and you still have quite a bit more room to lean it out...looks like a pretty conservative tune (a/f ratio).

nice numbers.... any videos from Dyno?

The TRD kit comes with a higher flow fuel pump

Haha...12's are reserved for only the fastest of fast street cars up here. I'd expect low-mid 14's at this altitude.

I didn't do any NA tuning like I did on the 4Runner because I always knew I was going to S/C - so I just waited. I'm sure there is plenty of power to be had by tuning NA, though - I've seen some of the results that people have had with dyno tuning Unichips, etc.
