1GR-FE F/I Mods and Dyno's

I see you @OVTune . When the time is right, need to post up some before and afters.

 

Go back to sleep

 

I didn’t get a before tune dyno sheet, but here is one of the afters. I think actually this pic I am posting is comparing tune to stock, tune being the green line.

Numbers were
TRD Tune: 323 HP / 318 TQ
OVTune: 343 HP / 329 TQ
About the truck when it was on the dyno:
Magnuson supercharger w/ 2.85 pulley. Has the bypass valve jet removed.
AFE “cold” air intake (dry filter)
JBA shortie headers w/ factory cats welded on.
Banks 3” Monster exhaust
Deatschwerks 255lph fuel pump

Dyno runs were done on stock tire size 265/65/r17

Now I just wish I could get on the dyno to see what difference my valve body kit and urd ypipe made.

 

Good job! Thanks for posting up! The best thing about your dyno is that your timing is very safe, and you made extra power.

As a point of reference, on my friend's N/A 1GR picked up about 20 whp. In the mid to high rpm range. On an N/A engine! I'll have to look it up again, but it is in the N/A dyno thread. Lucario Runner's 4Runner.

 

It’s crazy how much potential toyota left with these engines from the factory. I think it’s crazy that this truck has just over 100 more hp than from the factory

 

Stock Y-pipe?

 

Yeah, my urd ypipe didn’t ship in time unfortunately

 

Copying this over.

 

1997 tacoma reg cab 3.4 with 565,000 with supercharger
Trucks weight is 3200 pounds
Numbers are
245 HP. REAR WHEEL
270 TQ. REAR WHEEL

 

Mods: 2.0” pulley, Walbro 255 fuel pump, JBA LT headers, URD y-pipe, URD TCAI, 76mm throttle body, water/methanol injection, 7th injector, UCON-EMS

 

Very well laid out. Those are some impressive torque numbers.

I can't think of any other mods that might affect engine performance
Dyno was Dynojet Research 424lc in ground AWD dyno (rear wheels only)
Elevation 4500'
Temp at time 95* to 100*F. Humidity was probably in the teens (possibly single digit or low 20s). Not sure but those are good ballpark for temp & humidity.

 

Thank you for the indepth details, sir.

 

@ThomasMore66, could you update more mods please?

Meh.. I feel like it was done wrong and traction was kicking in, but here it is.

2012 TRD Sport V6
298.2 HP/ 317.5 TQ on Mustang Dyno

- TRD JustDSM tuned
- 2.8 Qwikchange pulley
- Mightytacoman 3* Cam gears
- FIC 650cc injectors
- NGK Ruthenium HX 95125 plugs .039 gap
- AEM 320LPH E85 capable fuel pump
- NST lightweight OE billet crank/ WP pulley
- NST custom built lightweight billet supercharger crank pulley
- Mishimoto 160* thermostat
- RatioTek HD upgraded transmission valve body
- Bosch 010 auxiliary supercharger coolant pump retrofit
- Custom 1.5 quart supercharger coolant reservoir byMightytacoman
- Modified Y-pipe
- Black Widow Venom 250 muffler



If we are basing it purely off the original post Dyno graph of the all OE 1GR, that would indicate a 106.5 HP gain over OE with the modded Supercharger.

 

how did your AFRs look?
