Can't break into the 9's...
 

Seems like I've done every mod to this Evo and I STILL can't break into the 9's. Car weighs 3000lbs without me and is making 650whp uncorrected on a Mustang in Denver at 5280 feet. Keep in mind its harder to make more power up here at this altitude. My boost is set at 38 psi and I think we're choking the T3 housing so T4 twin scroll housing/manifold is next but I would think I could at least break into the 9's with the current setup. My trap speed is pretty high.

I know theres some room for improvement on my 60'. Should I be staging with my ebrake and would that help improve my time? Any suggestions?

What suspension are you running?

AWD Motorsports D2 coilovers with drag spec springs

What MPH are you shifting into 2nd gear? Are you sure the car has full traction before going into 2nd? Try getting your clutch out a bit faster, and also, are you using NLTS? That will help a lot.

Also, that is a huge turbo for only 143mph. Most people in your MPH range are running a 62mm. Maybe downgrade your turbo for something more responsive?

Car will go 9s, it just needs proper driving. Unfortunately its hard to study off that video with that crazy loud integra.

Good question on the 2nd gear. I'll have to look at my logs. My shift light is set at 7800 and my rev limit is set to 8500 which it hits when I hit the trap. I am using NLTS. Keep in mind at this altitude, it takes a larger turbo to run those times compared to sea level. We do have a conservative tune and maybe we can bump it up some more. I'm just tired of putting engines in it. I thought about going down to a 6466. The current turbo is a JB, not a BB. Thanks for the advice!

Here's a few more videos when I was running a 2.0 with a 3586.

And here's Carz Evo running the same track with the same turbo with similar MPH but its a lighter car-

Putting different motors in just to change the set up? or you mean motor failure ?

Motor failures.
2.0 lost a wrist pin
After that it went through two 2.4LR engines
Third 2.4LR is staying together

Previous owner went through 4-5 engines so the car itself may hold the record for the most engines lost.

Holy ****....

Trust me, I ran about 90 10.0's... The wall/struggle between 10.0 and 9.9 is real.

Normally you need to sit on the limiter a bit before going into 2nd until you you feel that forward momentum throw you back into your seat (traction) after the initial launch.

Just for discussion here is a 9 sec slip from 2011 that shows the incrementals to compare.

Of course this was at a track much closer to sea level (sorry don't know what the DA was that day)

My car weighed roughly 3030 w/ me in it and all safety stuff needed to run sub 10.0

It looks as though the 330' is the key as with most it's likely the 1-2 shift as you can see that 1 tenth difference at the 330' mark turn into the difference of a 9.999 sec pass vs a 10.248

You actually had me by .01 in the 60'

Best of luck reaching your goal :beer:

I fill you man I leave in Colorado and is more difficult to make numbers that in sea level I talk to a lot of tuner and they have the same respond. is the altitude you will be killing in sea level.

The 1-2 shift is the biggest thing in my opinion if your 60' is in a good area. Make sure you're above 40mph if you're on stock EVO 8 trans gearing and use NLTS.

Ok, that helps. Normally I shift when I see the shift light come on.

Thanks! Yeah I agree its probably the 1st to 2nd shift thats getting me in the 330 mark. Maybe try to shift quicker too. I know I need more seat time with this new setup. It is frustrating that I have gone from a 10.1 to a 10.2 with a larger turbo but again its a very conservative tune compared to the older tune which is more aggressive.

I'd love to take car down to sea level, get it re-tuned and run the 1/4 mile just to see what it would do and feel the power. When it comes to performance vehicles, it sucks living up at this altitude!

Great info! Thanks!
