Went to the track this morning
R/T - .746
60' - 2.282
330 - 6.253
1/8 - 9.549
MPH - 72.56
1000 - .000(n/a)
1/4 - 14.796
MPH - 94.39
Sunny 75 degrees, head wind constant 30+ mph. How much quicker you guys think without the wind?
mods: K&N panel, TS ECU, new piping w/ Magnaflow resonator, stock mufflers, Good'ole RS-A.

The only car that I could tell was comparable and completely stock was a Hemi Charger, it ran a 14.9 @ 91. But those cars don't slip through the wind as well as ours.

I ran against one and below 80 or so they pull on us...above 80 is where they shut down which is why the trap was so low, but still 14.9 isn't that fast
On the other hand, you ran a very good time I know what you mean about spinning..it's so hard to get traction in a FWD car from a stop...

Thanks, I'll just have to wait until they open up again in Jan; and when I have all damn day to wait for a run. Launch with a FWD auto definitely takes patience and practic, I thought I got it down pretty good on the street.

I dynoed at 211whp with just the Nismo CAI. I wonder does that mean CAI=Repiped exhaust?
You should redyno with your new stuff and on removing the obvious heavy items. But personally I think I would like to run it like I have it equipped for daily driving. That's why I am thinking of ditching the sub box and finding a lighter weight alternative to add some bass.

With Nismo CAI and a few cheap mods, I hit 2?1whp@6500rpm. The new y-pipe added more torque everywhere, and the TS ECU gives it an extra kick.
I am pretty sure the peak is still around @6500. I do fell the power drop at 6800. With all yours mods, your peak rpm should be the similar or better.

I pulled 22 more MPH from 1/8 mile. The car pulled pretty hard even with some headwind. Traction was more of a problem with that run. I just couldn't wait another 2 hours for my group to get another turn, there were 400 cars there. I guess I will dyno again after the holidays.

The curve I would like is the one from CE for their y-pipe ad:

Here is my dyno with stock A/F before ECU and y-pipe. The tech guy basically did 3 pulls with no cooling down. 212.9 and 224.3

There was a member here that had a peak of ~260 @ 6500 on a Mustang Dyno. The Mustang dyno was set up poorly, and when that same member got on a DJ, the numbers were quite a bit lower, with a lower peak ( 22x@5600-5800) and then dropped off from there.
#32
Nice numbers. On the Mustang dyno I had CAI, Amsoil, grounding kit, 350z thermostat.
I got a few pulls this morning on a Dynojet ... at Extreme Ms., MD and my A/F was off the chart at 18... 199WHP in 2nd. I decide not to go further with that. Too dangerous since the ECU does not read O2 signals at WOT and does not compensate A/F.
Many posts talked about bad MAF's, so I took it out, studied it and began drilling holes in it to increase air flow. If its bad, might as well experiment. I doubled the size of the hole above the hot wire. Air flow got a bit better. Grabbed my Dremel and did a few pin holes in the back. When you look at the opening where the IAT sensor is, you now see the holes in the back, horizontally in line with the A/F hot wire in the back. Now the MAF air flow is closer to the upper range of the specs and my Long Term trims are near zero. I have to review a lot of datalogs to see how the other sensors are reacting. I may do a few more pulls soon.
BTW, If you forget to reconnect the MAF you will know. The engine has little power and shifting in drive or reverse is very harsh and noisy, like having loose motor mounts. Don't ask.

Adding more diameter to the entire MAF housing will lean the mixture.

The engine temp while driving 30mph+ is around 181-183. If I stop, it climbs to 198 because the fans will only kick in at 203F. This defeats the reason I got a colder thermostat. I am planning some rewiring to get those fans to start sooner.
I did not touch the MAF housing. I modified the sensor inside the housing.
Here you can see picture of the MAF sensor(front).
Top of sensor:
The air enters at the front, passes over the sensors, turns left inside, comes back forward and is then sucked out from the top and bottom of the sensor. Like I said, I drilled 3 pin holes behind the hot wire to force some of the air throught the back, avoiding this "chicane".
It did speed up the air over the sensor. Autoenginuity is showing that my MAF reading is almost 30% higher and the Long term trims are staying at zero. I am pretty stoic 1K-3K and a tad rich 4K-6K. Happy so far. I have to do some data logging to check A/F at WOT.
