Lets get some serious things going with the 2.8L V6.

On our car I had an intake filter from my 1988 Nissan 300ZX Turbo Shiro laying around, It is a K&N filter cone, nothing fancy. Installed it in about 30 minutes with things I have laying around.

Not a bad little mod, car feels a bit better, OEM Bypass valve is annoying though. Will post pics soon. Also have to make a shield for it. A trip to Home Depot racing will get that done.:lol:

Our list of cars:

1988 300zx turbo shiro special (hit on the side, was the other toy)
2003 Dodge SRT-4 (our toy car, Built, capable of 750whp)
2003 SAAB 9-5 Aero
2004 BMW 330Ci ZHP (will be turbocharged next year)
2008 SAAB 9-3 Aero (new to us, got the first mod on)

Not sure what you really want as far as information but this is what I have had done so far to my 2006 9-3 Aero and what I'm planning on doing soon.

Intake:
BSR Optiflow Intake (soon going with MapTun airfilterbox upgrade)

Exhaust:
Modified BSR exhaust by Velocity Tuning with Ferrita downpipe

Electronics:
MapTun Stage 1 soon to be Stage 3 by this summer

Engine:
2.8L V6T with 6 speed manual transmission, GenuineSaab short shifter installed. Next up is MapTun intercooler for this summer.

I want to put together a thread where at a glance V6 guys/Gals can go into and see what is available for the cars.

BSR exhaust by Velocity Tuning with Ferrita downpipe
Billybobs exhaust system 3" turboback (sample)

I will start writing to some of my contacts in the aftermarket biz.

Stock injectors are Bosch 0 280 156 129 and they are 33 lb/hr injectors (346cc/min, refered as 350cc/min).

Spray Type: E (Twin Beam)
Spray Angle: 20Âş
Total length: 64mm (standard body)
Impedance: 12 ohm

Injectors



Well did a little research for those that want to up the ante on their V6 2.8L Aero.

We can provide the proper flow and fit for the Saab 2.8 Turbo.
But as far as matching that twin-beam spray pattern - that is for the stock, emissions controlled engine and not an option for any of our high performance injectors.
With 500whp I calculate 650cc/min at 3 bar for the proper flow rate. I have this same EV14-Standard in seven different flow rates from 490cc up to 1200cc.
Click the link to see the 650cc option.

06 9-3 aero v6T auto

bsr optiflow intake
maptun stage 1
09 aero wheels 225/50 17"
Member of unknown motorsports on Long Island, NY

Pending items for the spring
Polyeurethane bushings
modified borla exhaust via universal kit
eurospec front bumper (still researching on what I want)

Question: will I need an intercooler if I get a downpipe? or is that if I just tune it to maptun stage 3?
 
#9 ·
You won't need an intercooler for stage 1. I believe that's only for stage 3. You should be just fine if you want to install the downpipe.

And this is based on?
Did you dyno your car with before and after data?

Vtuner uses HPTuners which is readily available to anyone with money on hand.

BTW, Intake and exhaust on any turbocharged vehicle definitely is a "mod".
Remember the engine is a large vacuum pump, get rid of one restriction and it frees up power. Even on todays torque target based, solenoid driven boost systems there are gains to be had.

Also i don't see the bang for buck ratio when paying $899.

Looks like we have to dyno the car and dispel some myths, and misinformation based on what one guy told another and that guy yet told another and then it becomes the written bible on the car.

I'm not just a newbie when it comes to cars... Seen plenty when I ran a dyno shop.

I don't see what other mod/s you can do for under $899 that is going to give you the equivalent HP gain as a tune.

Yes, Vtuner uses hptuners, but unless a person knows what they are doing it will be of little use purchasing it on there own.

I would say the majority of the tuned V6 people have chosen Vtuner for a reason because it really is the best bang for your buck.

I am not knocking Brians excellent work on the V6 turbo Aero, he is at my backyard afterall.

The power that can be had through HPtuners/VTuner software is about $25-$200 for other turbocharged vehicles so to me it isn't bang for my buck.
It is harder to extract power on SAAB/BMW vehicles and the prices go up beyond what I call bang for the buck.

If someone doesn't know cars in general then dishing out $899 for Brians excellent tune is a good start. Sometimes those are the same guys that also get brakes done at the dealer for $600+.

What I am trying to state is that I don't see hard evidence for saying a intake is not a mod, rarely do you see on here guys dynoing their mods. It is install then go.

Lets see if the car pushed 250/255hp at the crank then that means the car puts down about 210-217whp. Our Stock SRT4 did 215whp/246wtq, we added a better wastegate actuator and that allowed the car to hold boost to redline on the factory anemic mitsubishi turbo, it churned out 241whp. cost? $50

seeing that some of these cars trap 96-97mph stock
Car rocketed from a stock 13.91@100 to 12.65@110 with $1500 in mods, that included a huge portion on drag tires and wheels, stock turbo. bang for the buck? yup.

Hey man since you know plenty of dyno shops in your area, do you know of some around the Boston area at all..? Especially by Hingham or the south shore? I know its a long shot but just wondering. My brother goes to WPI so next time I go there I might have to hit up a dyno shop to post the numbers of the Stage 1 tune. Any one near you that you recommend?

hahaha... I liked this thread until I started reading what Wagon turned it into... thanks but no thanks.

by the way, maptun's strutbar is for the 4 cyl only as well, no1 yet has one for the V6 (at least mass produced)

also, there are now 2 places for a carbon fiber rear spoiler: Maptun and ____? I forget the other but I know it's somewhere for under $150
 
#29 · (Edited)
Yeah Wagon did kinda ruin it.. However, I know that it says its for the V6, but I went to Velocity Tuning and we did a quick measurement with one and it actually might work with some modification.. The expansion tank will just be not accessible when installed.. I'll keep you posted since I'm going to try and install it soon ;ol;.
 
#30 ·
Sorry guys the thread title said V6 on Saab forum. Not 4cyl or a Neon forum. I also made the point that an aftermarket intake is not a performance mod and that the vtune is the best bang for the buck for the V6T that simple there is no argument since there is TONS of info on both of those.

I was checking out his vid where he ran a 14.xx with stage 0. I'm coming from a 290 whp grand prix which I ran a 12.98 @107, I'm confused....obviously there are a lot of other things to consider but seems like 20whp wouldn't be a full sec behind.
 
#47 ·
I think his video of the 102mph run is on his Stage 0. which does about 270whp, why is it advertised at the crank? some guys care more about what the engine is theoretically making then actual power used at the wheels.

But I noticed it is common practice for Euro cars. I say it is hard to tell since some people use different fluids, engines are not all the same from the factory although they should be and not all are 100%. Through the ECM you can tell how my airflow demand there is thus with some of this info calculating power at the crank can be done.

hey I just wanted to chime in about the dyno's I am very familar with dent sport they do some insane work i'm talking about more then grease monkeys... real engineers over there. They have done alot of custom fabs and have built some beautiful cars and have been in the x games. My buddy built his 2.0 wrx of there and was rocking well over 400 crank with just a spit and a wish. They have had a few saabs through there as well as other cars.

Ok so set up a day to go into ACS racing in Hanover for Monday of next week. Seemed very friendly and the guy on the phone said I could swap out the BSR intake for the stock airbox and do 3 pulls. Can't wait to see the results ;ol;
 
#52 ·
Honestly, I'm not 100% convinced that the results from a dyno with a stock box and optiflow will show accurate differences. The problem with the CAI is that it takes in hotter air from the engine bay. The stock box isn't supposed to be very restrictive and it acts as a "snorkel" to bring in colder air temperatures.

You can certainly watch the intake air temps on hptuners and I bet that the stock box will bring in colder temps, as minimal as it may or may not be.
 
#53 ·
On most turbo cars the cold air that gets brought in is then heated by the Turbo which then goes through the intercooler and cools down.

Sometimes the software will not show much in changes from adding a cold air intake due to that reason.

What you are doing by adding an engine mounted filter is increasing the volume that can be ingested by the turbo.
 
#55 ·
I haven't looked at this to deeply, is there a way to make an actual CAI by going through the fender well or down by the grill openings?
