60-130 is TOTALLY different then the 1/4. In my 6spd with 825HP, the best non dedicated 60-130 we could get and verified by DIVEXTREME was 6.04. My car best trap was 135mph though. There are guys that trap 135 running 10.5sec and 60-130mph at around 5.50sec.

Dan,

Quick question for advice:

I mean to dyno the car and the only dyno here that I know of for a 4WD car is a Dynojet.

I seem to remember reading somewhere that it does not like our PCars...

Is that true or the DJet will be fine.

Any special settings, recommendations for doing the run?
3 gear pull? 4th gear? etc...?

A DynoJet is like a guy in the woods rolling on 2 big logs in the water. For RWD no problem, for AWD, problem as these rollers are not connected. The Mustang Dyno, Dyno Dynamics are connected via a coupler or belt so the front and rear rollers move the same. When I put my car on a AWD DynoJet locally here, the front and rear wheel speeds would never match up so the car would think it was having an issue or the numbers were way off. That is why most guys that have these really high numbers are doing it using a RWD dyno jet by disconnecting the front half shafts. That really is not real world numbers.

To be honest the dyno is so worthless and you have set a benchmark of how PBox testing should be done. Your car is in motion getting proper airflow and real world resistance. I would continue to mod and use those baselines to show your cars success.

OK.
Better not spend useless $$ then.

I'm going out for my 200mph attempt tonight. Wish me luck.

Yousef is coming out to play as well. He fitted your straight pipes and raced it yesterday.

He walked the other car big time. I was there to watch ! I'll let him post the details.

I will be PBox(ing) his car tonight as well. Should make for some very interesting results.

I PBoxed his car a week back when it had 4 cracked coil packs, 6 completely burned out plugs and air leaks in 3 hoses.

I was amazed! His car managed an incredible time 60-130 pull despite the problems!

I have his DBN files. I will post results if he wants me to.

Since then, he changed out all coil packs and plugs and replaced the hoses.

No bro! You owe me nothing!
Yousef is all heart and an all 'round great guy.

Besides that, he's a fellow 6speeder!
The way I see it, helping each other out is what this community is all about!

Will try to take pics and grab some vid as well.

IIRC seventh gear is more of an overdrive gear rather than being there for actual performance.

Either way too hot or way to humid.

Haven't had a chance to go for a second run yet.

Thanks for the blog!

Not that simple.

The car in stock tune hits a top speed of 194 MPH and is limited to that top speed by the ECU.

This top speed can be reached in 6th gear.
At that point, if you shift into seventh, and since it has already reached the speed limited by the ECU, seventh becomes a pure overdrive function.
If, however you shift into seventh at, say, 180 MPH, the car can keep accelerating in seventh up to 194 MPH as well.

Scott Slauson removes the speed limit in from the ECU in the Softronic tune which enables the car to stretch further.
In my case, 196 MPH became a rev limiter issue in 6th gear and I did not shift into seventh as I was in Sport + Mode.
