12.5 @ 110 Mph

[Doug_O]

First night out on slicks (MH 23 X 7.5 X 15)



However, I was only able to make one pass. See below pics
The hood is about 6 years old, and I guess she just gave up. The stock latch stayed shut, just the carbon fiber "skin" ripped off. It was too much for the wimpy locking hood pins.
It blew off right at the end of the run. Pretty humorous for anyone watching. Luckily, nobody was injured. I find it interesting how it ripped apart.



Well, time to look for another one.

Also, here are some datalogs from that pass. CalumSult w/Logworks is a powerful tool.

This one clearly shows a pegged MAF
Although, the AFR is hovering around 11.0-11.5


This shows about 90% duty cycle on the injectors (370cc at 4Bar)


I just can't believe my hood blew off

BAHAHAHAHAHAHAA! SOMEONE had to have gotten that on video.

Anyhow, nice run man!

[Benito Malito]

That RT is impressive. I was going to ask where you shifted but there it is. Can you fill me in a bit on your set-up?

Sorry about the hood.

[Doug_O]

The setup is:
U13 DET
GTiR mani and turbo
13PSI
JWT 4Bar Setup
3" Exhaust
Slicks

Woah!!!

Nice time!

[Kleensleeper]

Nice times.

[NissanGuy]

nice, looks like its time for a MAF upgrade

[BOBO]

what brand CF hood was it? I've never seen that happen before! that's pretty wild.

Nice to see some new numbers from you again Doug, i know its been a while, your track probably was closed due to weather huh, Nice runs man and your reaction time was great for your first pass, next time I go out im gonna be on slicks. Just went and weighed my car today too, its heavier than i thought, 2340lbs I have another 100lbs im gonna take off then another 50lbs worth when im actually going to the track, like the passenger seat and rear seats. But i cant wait, its probably not going to be till the beginning of october. I will have my slicks by then, Ill be running 16-17psi on 100 octane mixed in. Looking for that 11.9. what do ya think doug, think its possible.

I really don't know. I got it from a group buy on the other forum about 5-6 years ago. The GB was pretty much a bust, but somehow I got mine. It was showing its age.

What's up man. You're gonna love slicks. I was almost shocked when I matted it in 2nd and she was gone. As for the 11.9 it's gonna come down to the launch. Looks like your cars got the power (SNAP!), just gotta use it.

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.

[ashtonsser]

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
