2024 Tacoma Bone Stock on 87 Octane Goes Faster in the 1/4 Mile Than with an AFE Intake & 92 Octane

Some real world dragstrip testing results. My bone stock 2024 Toyota Tacoma 4x4 TRD Off Road double cab long bed automatic transmission on 87 octane regular unleaded went 15.84 @ 87 MPH.

With an AFE Momentum GT Cold Air Intake System w/ Pro 5R Filter on 92 octane super unleaded it went slower 16.09 @ 86 MPH in the 1/4 mile. Riddle me that. Stillen said their truck dyno’d 20 more HP on 92 octane when they switched from 87.

Both runs were in 4HI no wheelspin in Sport mode.

Wait till you put that billet TRD oil cap on there

 

Was the second run after lunch?

 

Woah woah slow down partner, you better check the placement of the floor mats before doing that

 

Computer had no time to calibrate air flow and octane, run a tank through and try again

 

Also, run it in 2wd. Car and Driver did testing and the Tacoma ran faster in 2wd than 4hi.

 

Stock tunes are weird, you'd think it would advance the hell out of the timing and let boost climb a smidge higher, but it clearly didnt.

It's not a perfect test, both runs are basically identical.

Clearly a tune is next.

Did you stall launch?

 

i had the intake installed and been running it on 92 octane since November 2024.

 

It ran even slower. 16.21 at 88 MPH in 2wd.

 

i stalled it around 1,500-2,000 RPM off the line.

 

Just for ref. 2021 SR5

I had ran 15.5x @92ish mph a couple times with under 1K mi on the odo. I posted time slips at the time.

At sea level.

 

Because of wheel spin?

 

You changed 2 variables and did only 1 run each?

Try 1 variable at a time with 10 runs per averaged.

Were the humidity and temperature the same during both configurations?

Was the tank filled exactly the same amount each run?

Were the tires, tire pressure, and tread wear identical for each run?

Did you forget to take out the kid's car seat with the second run?

 

Are you going to pay his drag strip fees?

 

The trick is to get YouTube to pay them

 

Why would I? I don't give a fuck about quarter mile times in a stock pickup.

But these results are meaningless as is.

 

No wheelspin. I flat the rear tires to 20 psi.

 

i did multiple passes. These were the best runs from each outing. The “stock” runs and “modded” runs were 1 year apart at different events at the same track with same conditions. Same tires, same pressures. I went in with a full gas tank at both events. Truck was the same weight at both events as well. I tried to make everything the same to keep everything consistent. It’s a yearly 4x4 Shootout and they put up more than $10,000 in prizes.

 

Was the first gen racing too? Or was it going to fix the sprinklers at the end of the strip?

 

If there's no traction advantage I don't see how it would be faster.
