It's mentioned in one of his other threads. And will probably be discussed here in the next episode lol.

speed density, i want to know more.....

[Decepticon]

Uuummm...where's the next episode airing?

[MazdaGaragePat]

So my 12.501 and 12.01 were both shown with almost the same setup.
But in last run:...

It had more power due to higher boost and advanced ignition.
It was some 90 lbs lighter due to interior strip.
There were quicker shifts due to 325 ms to 225 ms no-lift-shift WOT box time reduction.
It was better tire traction due to ambient temperature growth.

Since I had no will to strip the door panels, audio, floor carpet etc and to change my current Federal 595 RS-R tires, further time improvement depended on power mainly.
With top end power drop in my last dyno run I suspected several bottle necks in my current BT setup:
- dual 2" cat-back (some 2.75" overall estimated)
- 3" MAF housing w air flow straightener
- 3 ft of 2" pipe off the compressor outlet
- T3 divided turbine housing

Since I wasn't able to switch to T4 or TiAL housing turbo-kit shortly, I decided to modify intake and exhaust at first.
And since my GT3076R was almost maxed out I decided to switch to FP 3076 HTA.

So I've changed my custom complicated stainless steel intake...



...with classic aluminum one utilizing 4" inlet to compressor and 2.5" outlet off compressor...

...and saved some 6 lbs with these mods.

To empty the space for 4" intake I've also installed the smaller battery, saving additional 12 lbs.


I've changed stock 60 lbs driver seat with 22 lbs Sparco Evo II one.

So I've saved additional 56 lbs by the way

In addition I've changed Denso ITV22 with Denso ITV24 (just in case), stock BPV with Turbosmart BPV, straightened and shortened vacuum hoses.

2" dual muffler pipes were changed with 3" ones (3" overall diameter estimated since main cat-back pipe was still 3").

Since it was irrational to install MAF sensor to 4" intake I decided to switch to speed density fuel management...

... utilizing 4 bar Denso MAP sensor


So we've finished my car assembly at friday night (May 27) and I had no time to test and tune it in proper way cause friday night drag session was nearly to be closed soon.
So I tuned WG duty and speed density map almost virtually




Though with 30 psi tire pressure and 5800 launch revs I've hit 11.605 sec at the first attempt !
I was really shocked with this time !
But with my new setup untuned and untested I didn't know even the actual boost hold in that run. I only knew it was above 22.5 psi the whole run (cause factory MAP sensor was maxed out) but 27.5 psi somewhere at 5th gear (by my STRI boost gauge) cause I haven't logged my Denso MAP data that time, just OBD-II PIDs.

I was afraid of running it untuned anymore with such level of boost.
So I've dropped the WG duty and tire pressure to 22 psi both and done two more runs.
In second run I've missed the 3rd gear and the third run was also not perfect with considerably lower speed trap and only 11.930 ET @ 22 psi of boost.

Is thread to be contunied ?
Definately YES !
BUT with 27 psi tuned and tested.
I hope my engine will withstand it lol
So let me take a little break

you a believer yet Darksun? hahahaha.

Pat does it right.

[BrianB6]

ok.......this is some cool shit

[Abilor]

Nice!! Get it tuned n run some 10's!!

[PunjabiPlaya]

bring that thing over here so I can buy you some beer

[rigor]

did you gut the intake mani?

[Wilksy]

Ight that's all I wanted to know. Not saying I'm a beliver in a fast Ms6 buts facts are facts

Car with x amount of power and x amount of weight with an X 60ft will put out your kinda numbers. Technically your running like 3-4 tenths slower that that setup should go.

Not knowing your 60fts is a pain in the dick. Oh well good luck with build.

I like that one silent Ukranian did what dozens of Americans were all bragging about and shooting for. Good work man, very cool.

me thinks superskater is still fastest MS6 in the USA, just like it says.

i also dont have a built motor with PnP head or a T3 1.06 hotside or an aftermarket clutch. all things considered i was launching a full 1000 RPM's sooner on a much more tame setup so it would prob be a close race if all things were equal...........

o yea my car weights 3600 lbs with me in it, what was your curb weight after you stripped it pat?

This is what I am talking about. Just when everyones balls were 11 shades of blue, some guy comes out of fucking nowhere and cleans out all your pipes.

If your gana do it DO IT.. Nothing like coming out of the blind spot to cross the line first

[Stealth01]

Fucking awesome, Pat. And I only understand about half of what you said because I'm mechanically retarded.

[MPSdriver]

Awesome!
May I ask what your goal is for this car... I sincerly hope it's somewhere near what you've done to that E30

[mason]

GREAT JOB!

[cocoanton]

Just wanted to chime in and say congrats on the 11 and a great build from a fellow european!
