Question for those experienced in boosting.

[Xanthos]

Three main reasons for me getting the six instead of the eight. 1) Insurance. This is probably the biggest reason. 2) Fuel economy. Least important, but still in the top three. And 3) I have a feeling the LLT will be more historically significant than the LS3, and I plan on keeping this car for a long time. You may not agree, but you're not going to change my mind. Call me 30 years from now if it still matters enough to you and we'll see who was right.

Now, as far as turbocharging goes - yes, I quite like the sound of a turbo six better than a N/A eight (sound meant literally - I like the exhaust note better and power output would be about the same). A turbo eight trumps all, but I definitely wouldn't be able to afford that. And no, I'm not planning on doing the turbo right off the bat. I'm planning on piecing together the kit in my garage over a year or so using clamps while I wait for somebody to crack the ECU, then dragging the entire thing to my exhaust shop and having them weld it all together. But yes, I am hell bent on having a turbo six.

P.S. - Good to know about the LNF injectors. I may look into that.

I'm not going to race it until I get a different car as my daily driver, once the Camaro is paid off, and I was going to completely overhaul the suspension first.

so what are YOU waiting for?

That's a better explanation than I had gotten before. I don't have an opinion about the historical significance of the V6 Camaro. So it doesn't matter to me now and probably won't in 30 years. It just seemed odd to me that you'd buy the V6 model when you clearly want the performance of a V8.

Yeah, but you drive a 600hp GTO. That clearly makes you insane.

With the proper tuning and maybe a methanol kit for good measure, you should be able to make a good amount of power reliably. Detonation is not your friend so tuning is key, especially with higher boost levels.

Man this is a big step and you got alot to learn (hopefully not the hard "$$" way)
Iam going to got out on a limb and say VVT = variable vale timing
IT dosnt control KNOCK . a knock sensor/ECU does that job .
It adjust CAM timing +/- to give more low end TQ and more high end HP and so on ...vs cam('s) being static .
Befor you start THINK about Turbo's you have to KNOW about tuning . You really need a way to change/control at least fuel if not more . You should read up on reflashing , piggy backing and stand alone ecu . and to my knowledge no one has tried that on a new Camaro . So for right now just work on getting the car and let someone else(aftermarket tuners) be to ginny pig on FI 3.6's

First Welcom to the Site matt55.

There are turbo and blower kits being built for the CTS version of the V6 in the Camaro. Yes they may be tuned differently, but It seems like the reasearch and development should transition well to the Camaro.

No it's not an LS2 or LS3 but I'm thinking we should be pretty close to reliable by the time we can buy one.

Here's preview for the upcomming CTS DI blower.

Thats what iam talking about , BTW what do you guys use for tuning ?

I'd probably go with Westers. I'm not experienced with tuning software and probably wouldn't want to play and learn at the same time on my blown baby.

So I think I'll send out for a custom tune and leave it to the experts.

And You? What do you recommend?

[Shadowsong]

I'd probably be using an SCT Exal 3, I prefer them to diablos

Actually, you should take a course on VVT. You seem to be mistaking what it does for how it does it. Yes VVT does adjust valve duration and cam timing to give more low end torque and high end horsepower. But the way it knows when to stop adjusting for more torque and horsepower is via a knock sensor, otherwise it would blow itself up. VVT timing doesn't have preset timing levels that it automatically uses at a given RPM. It has certain known variables and certain unknowns, for which it uses sensors (like O2, etc). An effect of this (whether intended or not) is that when a VVT engine detects knock, it will retard the timing till it no longer detects knock. Basically, it will assume that it is advancing the timing too much.

As for tune, I'll be having a custom dyno tune done once the box has been cracked.

The LTT's VVT ssytem cannot adjust durration, only cam timing and overlap.

The (most comon) way that an ECU will battle knock is the retard ignition timing.

Ah. I stand corrected. Either way, though, I don't think knock will be a problem at only 5 psi. Especially with an intercooler. It was decided earlier on that the biggest problem will be blown gaskets. That and waiting for somebody to crack the box.

I would love to take a class on VVT timing/tuning , where to sigh up ?

I have tuned VVT b4 on my Evo via ECUflash , Ive seen change in VVT gain HP and TQ on the dyno .

On my old Evo8 it didnt have VVT so I used cam gears to change to cams centerlines .

From all ive read and know(very little) when knock happines ignition timing is pulled , then even a 2nd more tame map(tune) is used by to ECU to help save your motor .

Maybe this D.I. 3.6 is different maybe it pull cam and ingition timing vs other motors that have VVT and only retards ignition timing .

The VVT maps ive seen are RPM/Load based not knock based .

O2's have nothing to do with knock control .

Main point Iam trying to make is you cant lets the knock sensor take the place of a tune

Dyno tune is a great idea ! !

I havent a clue what you GM guys use , I was just wondering .
I use ECUflash with EVOscan from data loging .
