first evo 8 vid check it out!
Mellon is where its at! haha.
Im shifting at about 7600. Chris said it would fall out of boost spool if you shift early. I may give it a shot. I mean it wouldn't hurt to try it. When do you shift? What kind of times etc?

Where do you guys usually shift on stock turbo? He males a good point my power and torque fall hard around 6200. Would I run better shifting at 6-6500 versus 7200-7600? Or would I be falling out of boost?
I think i will give the early shifting a shot. you can see the graph in the video after about 6500 the car hp and torque dies so i mean wouldn't shifting at 7500 be overkill? When i shift at 6200 (~about peak hp) i fall to ~4300 (~about peak torque) wouldn't this be a better way to shift it or am i wrong? Maybe run it to 7500 in the final gear at the end to save time of the shift

My shifting on my 12.00 pass (7.7 1/8):
2-step: 5000
1st: 6000
2nd: 6000
3rd: 6500
The big thing to remember is that after 6k the power starts to drop off on the stock turbo and so you get less acceleration as a result. Dropping to your torque peak is fine, torque and horsepower are the same thing just calculated different ways, so as long as you're between the two peaks you're golden.
I realize that slow re-spool is a concern, which is why I asked about no lift to shift (NLTS), which definitely helps to fight that.

haha no i will definitely be lifting to shift. I know it hurts the time but i dont want to hurt the tranny. I know it can be done correct but im not gonna chance it. What kind of mods where you running and what psi when you went 12.00? Just curious. Im definetely gonna try shifting about 6200 and see what happens. I mean youre gonna be at the end of 4th reguardless of what rpm you shift so its not like you would really shift anymore than shifting at 7500. Do 6 speed cars run out of 4th and need 5th for the 1/4? or should i be fine to stay in 4th im sure ill have to just see for myself.

Mods and boost are in my sig, keeping in mind that I'm on stock '03 turbo/cams/FMIC. I put down 308 at DB Performance in Rogers, MN (Dyno Dynamics that reads super super low), but I'm expecting around 370 on MAP's Dynojet at an upcoming dyno day. From what I've been told the car's good for maybe an 11.8 if I can really work it, but 11.9s are definitely doable with a new clutch. And yes, I believe the 6-speeds do need to hit 5th if they've got the stock rev limiter.
But as I said before, you're going to get most of your acceleration out of the car between your peak torque and peak hp, anything above that you're just wasting your time.
