Still no SC for V6 eh?

[Demon Hunter]

Really how much harder is it to run a centrifugal style super charger Like a procharger on these things. I can't imagine it would be that much different from the turbo tuning wise... Just fab up a mounting bracket and some piping, set the gearing for 5-6 psi. BAM! done....

If it was only that easy.

Twin turbo

Best bang for your buck.

A supercharger kit, based on the prices V-8 kits that are out there, are about $6500 for a complete kit plus install. A twin turbo kit will be similar priced.

The limiting factor will be the engine strength , the fuel injectors, the fuel pump on the DI car. Any of the systems will be more than enough to make a good amount of power.

So at $8000+ installed, how many V-6 guys will keep the 6 vs going with a V-8 car?

I will. For one, I love this car and love the idea of putting down 400 at the wheels in a V6. I'm keeping this car forever, and I'm planning on getting the most of it.

+1 Amen brother!

[Dyk-NO]

Me too AMEN to that, It's kind of sad how the v6 imports that are even 5 - 10 years older can have great hp numbers cause they got options for parts and we don't lol! No love for domestics XD

The thing about a turbo is that it is exhaust driven. The more exhaust flow, the more air it draws in, the more air it compresses.

By straight definition, a centrifugal supercharger would be endlessly laggy. However, it gives a power increase, boost increases with engine rpm.

A turbo charger makes big torque. Huge torque. Off boost, the car should have the same power/torque as a non-turbo car, but once it comes up on boost, you get a huge hit in your back. People call this lag. Its just that the turbo makes so much power that what it was before, feels pretty weak.

If you size turbochargers correctly, you can make lots of low end power, lots of torque, and minimize peoples impressions of "lag".

Check out these dynocharts from IPS of their twin turbo kit vs a few different setups on a V-8 Camaro. http://www.camaro5.com/forums/showthread.php?t=91275

This. Bravo sir.

I was looking at the SAE papers on the 3.6L SIDI V6 yesterday. Interested in how much headroom was in the stock fuel injectors and fuel pump. The fuel pump has a bit of range in it,and the SAE paper even mentions turbocharging. By my math, there should be enough high pressure fuel pump for about 550 hp at the engine. I haven't figured out the fuel injectors yet. DI is a bit different with the fuel injector calculation. The SAE papers mention a few different styles of injector, even a few flow rates, but I didn't see a duty cycle that I could figure out. .

In all honesty, half of what you said, I did not understand lol. But it sounds very interesting... I got the gist of you saying there is lots of potential with the LLT?

If that's true, I can't wait till some more options come out! O_o

Well, based on the fuel pump, I see a bit of room before you have to think about changing the fuel pump(about 550 hp at the engine). The main obstacle to that being aftermarket DI pumps.

Even on a regular fuel injected car, aftermarket fuel pumps are an issue at a point. DI cars use much higher fuel pressures than current port fuel injectors. Typical fuel pressures on a PFI car are (3 bar) 43 psi.

The DI in the 3.6 was up to about 12 bar (176 psi) fuel pressure at maximum load. It can run higher than that up to about 20 bar according to the SAE paper.

The other limit on power, besides the fuel system, is the transmission. The Aisin AY6 transmission is used in a few other vehicle besides the Camaro though. The Toyota Tacoma folks have had some troubles with it. I want to look more into what the Holden Commodore folks have done in Australia. They have had more time with the trans than us Camaro owners.

Well. Transmission, clutch, axles? For the trans some Redline Shockproof Heavy would help to protect it. Its not always super happy with some types of synchros. The trans is not an impossible problem, there is always an answer, and not as complicated as the fuel system on a DI car.

This is the first FI thread in a long time that actually has an inspiring feel to it. Nice change from all the "Yep, we're making it...oh wait, just kidding" threads. I appreciate Stillen coming in here and I've learned a lot from what they have had to say.

[jagan323]

Yes, I did want to thank Sean for staying so close to this thread. Eventhough, it's another deadend FI thread. But I agree with CamaroDreams, definately have some interesting information in this thread.

I was thinking, if I can get some good at home car builders, or engineers... it shouldn't be impossible to get a homemade Supercharger running right? I mean, i think cars may be too overly complicated for me, but isn't the root of a car really just nuts and bolts? Man, gotta assemble this "dream team" LOL.

Well. I am not going to promise anything. I am just personally looking into it, as V-6 performance interests me. I am a V-6 kind of guy, but I have had a number of different cars and things over the years. My daily driver is a 8 cylinder car , my girlfriend has a V-6 Camaro.

STILLEN has worked with turbos, centrifugal, and positive displacement forced induction for everything from 300ZX's, to Titans , to Mustangs, to Camaros recently. Some setups designed, manufactured, installed, and tested all in house here in Costa Mesa.

There is only so much R & D time. Right now here at STILLEN they are working away on supercharger kits for 370's, G37, FX35 , coupes, convertibles, etc, etc.

Even if I can't do anything personally, I might be able to help to get another option to the market for the V-6 owners.
