Pretty nice. Your injectors are probably about done too. Pushing near 300 at the wheels I'd guess. ??

Ya know, I don't think it's that high. I keep thinking its in the 260 range. Regardless, a fuel/MAF upgrade may happen sooner than I planned.

My last dyno on the T25 at 12-13 PSI was 220HP and I was in the 106-108MPH.
Now I am right at 110MPH at just about the same boost pressure, and have been as high as 113MPH.

so were you launching in second gear, or just talking about second not spinning when you smash the gas, cuz thats all first and second would do at the track, on my vid you can hear the tires squeeling in first and second gear, haha, I always thought it would have been better to launch it in first to get a faster 60' but then that does take away one shift which could in turn make up for a slower 60'. Just let me know man, interesting.

Look at the datalog he posted. He definitely used first and shifted at 6k if I'm reading it correctly. BTW nice run on sentence.

I think you lay down more than 260. You are pegging what I assume is an Avenir or a bored DE MAF.

yeah definetely looks that way, he must be refering to when he hits in second, haha cuz ive tried launching in 2nd on the street 7k rpm launch and it just bogs bad, not even worth not having to shift, its way quicker to get yourself moving in 1st by feathering the clutch then punch it, and then hit 2nd as quick as possible, once you have some momentum foward second gear goes like a bat outta hell

Sorry for the confusion. I definately launch in 1st gear. However, things happen so fast in 1st, I really focus on getting the car into 2nd. Maybe, with the slicks, I can start doing something "productive" in 1st gear now.

tell me about it, there are going to be a couple changes to my suspension also to help keep things sticking to the ground, putting the complete sway bar front and rear es bushing sets on, and probably a gr2/coil over setup to keep the back from dipping soo much, yeah i figured you wouldnt have launched it in second. cuz it doesnt work on the streets that for sure. haha, street tires first gear doesnt go anywhere.

Bored DE MAF 54mm

Now that you mentioned my shift point, I really need to look at my shifting.

1st to 2nd - 6123
2nd to 3rd - 6192
3rd to 4th - 6783

I want

1st to 2nd - 7200
2nd to 3rd - 6700
3rd to 4th - 6600


Can we say shift light???

I didn't realize it was that bad. I didn't even hit full thottle in 1st. This datalog stuff is cool

Shifting a bit later would probably be advisable. You'll only know for sure when you dyno it. Mine didn't fall off till after 7k so that's where I shift.

The shift light in my pillar pod helps for sure.

its funny cuz most of the time i look at my speed when i shift, my tach is a little off 300rpms below at high revs, I shift into second as soon as i feel ive gotten moving enough, give 2nd till i cross over 60mph on my speedo, third till i cross 90mph, its weird cuz sometimes i do go by the tach but mostly the mph cuz i know what speed i redline at. haha, kinda makes it easier to tell you the truth than watching the tach bounce all over the place especially in first gear.
