The V6 looks to take kindly to mods..

Combine the precise a/f ratio control with vvt, and I have a feeling you'll be able to run a decent amount of boost, on the stock compression ratio, and on pump gas to boot. I may be wrong - but, even if you do put too much boost for the CR, the engine will just retard the timing till it stops sensing pre-ignition. You lose some power, but probably not more than the boost is adding for you.

Not to over-rate DI (I'd hate to see someone putting 20lbs of boost ), but

Totally talking out of his ass. Higher than recommended octane won't increase performance or efficiency in most vehicles, but it won't break anything.

20 lbs of boost and you would probably be seeing more problems then just CR issues - blown internals, anyone? Nah, I plan on doing an STS remote twin turbo (gotta make use of those fender gills somehow, right?) @ 5 psi some day. I think it'll be enough to net me as much power as I want (I'm shooting for a 13 second ET) while still running 87 gas on stock internals.

As opposed to a large loud V8 that doesn't really move much (Dodge/Ford)? That's much more American Ricer than a turbo.

Turbos are the ultimate power-adder, bar none.

I totally agree... if only we could convince the people in the 'Turbo vs. Supercharger' thread in the v8 section, they're all caught up on 'turbo lag'

[MerF]

I believe I haven't looked at that thread in a long time. The only people who believe in turbo lag are ones who've never actually ridden in a modded turbo'd car before.

Yea, but if it's anything like emissions equipment on most of GM's newer cars, if you remove those cats you're going to throw a CEL. Worst case scenario the car goes into "limp mode" (as with the Cobalt's) and shuts down about half its power.

Can't you get a tune for them? With a Mustang you can just have it ignore those sensors or get mil eliminators.

Yes, it's called an O2 simulator.

[Xanthos]

I plan on just swapping the cats with magnaflow OEM style high-flow replacements - if I have to buy four instead of two, so be it. Then after the flowmaster mufflers, it'll just be a matter of deciding whether I want to leave the stock resonators in place, replace them with glass packs, or just delete them entirely.

Whatever you call it. My point was, there are ways around it.

Not too many v6 cars are putting down this kind of power, and definitely not for such a reasonable price. I think the after market companies would be foolish to ignore the v6 crowd. I know that I am going for a v6 asap, and then, if I dislike it or for whatever reason am dissatisfied with it, I'll go for the SS convertible a year or two later.

I've had multiple turbo cars and turbo lag is a domestic fan's excuse for being closed minded.

Thats exactly what I was thinking, why spend over 1k on a cat-back when you can buy the parts yourself and install them, saving more then half the price. Plus if flowmasters make this V6 sound anything like previous GM V6's on flowmasters, I'm all over it, my little 3.1 sounds like a v8 at idle with my delta 40.
