Man it looks like you have a little positive camber. That goes a long way when you load the rear.

Having the right combination of facny parts helps too. A glide and an AMS 1000 on a slow ramp is likley the best case scenario anyone could ask for....but its not realistic for 99% of the people that would race in a street enviroment. still really stong info-the feathering is a serious issue with my Mickeys and my rear end is not stong enough to do a burnout every time I take the car ou to seek traction!

Cool vid. I wanted more tire smoke and black marks though. The best part of the whole thing is that it looks like you are having a blast with this car. I'm certainly jealous of that.

Trucks gonna roll out pretty hard if I can get it back together.

We have some good friends that live in Katy. We visited them last year and it's a beautiful area, we loved it!

I've actually been busy and I'll be using them lol Wiring blows!

Use the mickey on the track, that is where they are designed to work and they work very well.

Honestly still can't believe the life the nitto have offered compared to the mickey.

The tread is always like this, absolutely no feathering like the mickey



Just a little tire though, I run them on a 9" weld.




Honest to god truth the mickey go from amazing g to marbles in zero time when they feather under heavy power and breaking traction.... Too soft

The nitto break traction in a strange way too. They rumble on my car, very noticeable


With no air applied to the gate it makes 4psi of boost. 22psi on gate makes 22psi of boost. Past that the compressor is dying. 31 on the gate makes 25 at 6k and down to 23 by 7k

So in that vid... I go wot with no air on the gate... You can see it ride 4psi..... You then see me arm the ams1000 and it does the commanded ramp. I let it ride 4psi for a second so it can be seen what is happening.


I will take a pic of my actual ramp timing and pressures

Here is another vid same thing. To show u the roads are. Nothing special and plain asphalt


But the nitto is a God send for a street tire. IF you know how to use it. My mickeys will never touch the street again

Nitto 555r vbox roll in. 3.4 100-150, 4.1 60-130 - YouTube




I have never used the nt05

Excellent info as usual and at that sticker on your steering wheel.

How do you have the boost ramp rate setup for the track? Are you "all in" by 100 mph or so?

What kind of fuel flow numbers are you seeing at the top of high gear?

I don't have the best data in the world (spinning) but in high gear around 6400rpm it was flowing right around 1300 lb/hr of E85 so what is that translate to 1050 CHP or something? That was at 26lbs of boost. I'm pretty sure this was the hit that the rocker bolt back out on. I'll get much more clean data at the track Saturday.

To trap 165+ I'd assume its got to be all in earlier than that!

Its funny to watch his run- boost gauge stays pegged the whole time- and me with a 6 speed its bouncing around the whole pass like

Yeah sweet sticker, have to have it I'm an idiot lol


Here is the controller setup on the street. It's hitting full boost faster that 6.4 because the turbo dies up top. Beyond 22 on the gate the boost increases very slowly till its just done all together then drops

It's peaking around 115 on street

At the track I run a single stage time based.

On 8.50 pass i left on 6psi, it was 1.8 seconds (50mph) to full boost (21psi)

Thats a sizable amount of fuel at that rpm.

I see you start at "0" have you considered or tried to start at spring pressure? Your track ramp rate looks like my street rate Except you actually get traction. I need to make some big time adjustments to my street tune. Problem is that some of the guys i run with are 1200whp 996 cars.. They have all the weight in the rear and it makes it very hard to keep up unless i can bring the boost in early and try to use what they don't have (torque)

Using .80 on the scale that brings the car up to an estimated 1050 CHP.. I know conditions are not perfect but i expected to see Consumption numbers higher than that at that RPM range. BUT im far from an expert so i could be wrong?

I made a math error and multiplied rather than Dividing the numbers.. I know consumption numbers are not a direct reflection of HP but i hope to god that isnt correct. This stock Crank and 4 bolt block isnt going to last very long at "1250 ish whp"

This was around 1200rwhp on my car..... stock crank, Compstar rods. Single 88mm T4.
It was only held together by the flywheel/trans and the 2 rods clamping the journal together.

Luckily mine didn't really damage anything as the motor shut down due to loss of reluctor wheel signal I'm guessing.

You should build a motor before nothing is useable once that grenades.

Yeah I remember seeing that. I wouldn't mind a decent forged crank but I can't find a stock stroke dragon slayer anywhere.

I'd be willing to bet that his forced induction e85 set up is not .8 bsfc.

It's probably closer to 1:1
