The anticipation will be over soon and I will finally get behind the wheel of my newly born monster and I couldn’t be more excited.

All new mods include:

Weistec Stage 3 Supercharger
Weistec ECU Tune
Weistec 722.9 Valve Body & TCU Upgrade
Weistec Trunk Ice Tank
Weistec Billet Catch Can

Along with the blower I am adding a few other little goodies:

Custom electronic cut out’s
Evosport rotors
MHP's 180F thermostat
Dad’s CF vented hood
Braille lightweight battery
And a few CF accessories-front lip/roof spoiler and Mode Carbon's CF front grill

I am picking up the car some time this week and plan to have her on a dyno and drag strip this Saturday. I was able to get a baseline dyno number before the install and my car put down 450whp and 385wtq on a Mustang Dyno. And my car ran 11.73 at 120mhp my first time ever at a drag strip on street tires. I cant wait to see what it will put down on the dyno and at the strip now. (Baseline tests were with MHP longtube headers and catless mids with a Eurocharged tune and a Evosport pulley)

Here are some pics of everything from Weistec as well as baseline dyno graph.

Big thanks to both Steve @ Weistec and Marcin @ Speedriven

The comparison will be mind boggling!! CONGRATS!!!!

Hope you have some other tire plans.

I am working on it, trying to find something locally in a 16-17" but if I can't we will be in touch soon! Thanks Keith

Nice. Very sexy stuff. Cant wait to see the results.

All I can say is WoW !!!

Well i'm jealous of your new monster, and that shop looks amazing.

friggin' sweet, congrats

Merc63

Your times with headers are pretty close to mine.

Looking forward to when your done and we can compare stage 3 times.

Blown63

Looking forward to it! I interested to see how much stronger the car runs on 93 octane tune. Steve @ weistec told me that the cars running the higher octane tune run alot stronger. So I am interested to compare gains, what tune will you be running? Will you have a 91 tune?

CarHopper

Sigh. Envy isn't even a strong enough word for all of you guys running these stage 3 units.

Can't wait to see/hear the results.

Merc63

I have 94octane here but will probably run the 94 with the 91octane tune. Just a bit more safety with the boost.

skaarlaj

How much boost are you guys running without having to run race gas or drop compression? Also, what are the stock size injectors and what are a common upgrade size when going to a blower on pump gas? Awesome stuff guys!

Blown63

Where are you located that you have 94 octane?

What do you mean when you say for a bit more safety? Is there something wrong or unsafe with running 93 octane tune and if so what? I always though you should be tuned for whatever gas you run am I wrong?

M156Beast

He's basically full of it. If he's running 91 octane on his 91 tune, he won't be running "Safer" with 94 octane gas. Ahahhah

He's propabley going to cry again thinking I'm Jacob lol.

Merc63

A 91 tune will run less ignition timing than a 94 tune. Running higher octane fuel will provide more knock resistance before the knock sensor would need to retard timing from heat build up etc.

Skaarlaj, I'm not sure what the boost is tbh. Static compression is stock at 11.3:1, dynamic compression is altered for the blower via the cams to run under boost. The kit comes with larger injectors.

Jacob, go learn how an engine works and basic tuning principles. The higher the octane the better when playing with boost and high static compression engines. (if the fuels stoichiometric ratio remains constant)

jrcart

You are going to love it man...Congrats

M156Beast

I think you need a Doctor.

Blown63

I am kinda of confused, above you said running a higher octane will provide more knock resistance, which to me sounds like a positive, correct me if I am wrong. And then you said, the higher the octane the better when playing with boost.

So I think what you are trying to say is that its safer running a higher octane gas then what you are tuned for? Am I correct?

Thanks

The higher the octane number, the slower the explosion which in turn equals more resistance to detonation. So yes, if you are tuned for a lower octane number and use higher number fuel there would be that much more protection against detonation.

Think of it this way, a tune for a higher number would use more spark advance. The slower flame front on the higher number fuel woula allow the spark to ignite the fuel sooner on the compression stroke because the mixture would take longer to fully ignite. What a tuner is trying to do is get the mixture ignited as close to TDC as possible to take full advantage of the explosion created. That being said, if you tune for a faster explosion but ave a faster one, the full ignition of the mixture would be further down on the power stroke than optimal. Sure, you would be leaving some power on the table but it would be that much more resistant to detonation.

A fuels octane rating is its resistance to detonation. The higher the number the more it can handle pressure and heat before it explodes.

As the piston is coming up, the spark goes off creating a pressure wave (flame kernel). If you get too much pressure for the fuel it will start to self ignite a head of the flame kernel causing pinging aka knock.

With the blower, the air is compressed and becomes hotter, as the engine gets heat soaked this worsens. You want your fuel to be able to handle the increase in temps and pressure.

Weistec runs the air fuel mixture on the rich side so the extra fuel will help cool the intake charge as well.

rags260z

Yeah


Joe

Merc63

Is this a test lol.

All a race tune is, is more ignition advance combined with a high octane fuel. The advancing ignition creates more cylinder pressure, aka more force down on the piston. The higher octane fuel is needed to handle the increased pressure.

Blown63

I am trying to take this all in while trying to understand everything to the best of my ability. So what I am getting from all this is that running a 93+ octane tune is not recommended??? Is anyone else running a 93 octane tune?

What if I always ran 100 octane (or octane boosters) on my 93 tune would that be like you running 94 octane on a 91 tune? And be safer?

Thanks for the info guys you have passed your test lol

Merc63

Run your tune, you will be fine. The engine will protect itself with the knock sensors.

For extra safety/performance run a higher octane than your tune if you want or can.

Blown63

Thank you Merc I appriciate your advise.

So today I was reading the rules and regulations of the drag strip I will be attending on Saturday. How come it says that a roll cage is mandatory for cars running faster then 11.5? I am pretty sure that all drag strips have about the same rules but I know not everyone running faster then 11.5 on here have roll cages. Should I be concerned or are most drag strips lenient on these rules. The last drag strip i attended had no inpspection at all, they didn't even make me wear a helmet until after my first run. But thats because all the hillbillys were laughing that I brought a mercedes to a drag strip
