Twin turbo vs Supercharging LS motors? What's the vibe nowadays?

I also believe it is personal preference. I like mine because under boost it drives like a stock ss. the wife drives it and has no dramas at all. Now with std ride height and stock wheels the cops dont even look twice. Yet if i stand on it at 150 it will light both tyres up. Brutal power, which some like some hate.
As far as the heat issue i have had none whatsoever, and i still drive mine hard on days well over 40 degrees. And on the dyno it makes same power run after run back to back. Where a lot of blown cars will suffer heat soak and get lower and lower.
And the end of the day get what makes ya happy

Power per pound of boost (intercooled): Turbo > Centrifugal > PD blower

Thermally efficient (no intercooler): Centrifugal > PD Blower > Turbo

Longevity of driveline: Centrifugal > Turbo > PD Blower

Ultimate Power potential: Turbo > Centrifugal > PD Blower

Ease of install: Centrifugal > PD Blower > Turbo

Cost of Setup @ 400rwkw: Centrifugal > PD Blower > Turbo

Fuel Efficiency: Centrifugal > Turbo > PD Blower

Quarter Mile Potential: Turbo > Centrifugal > PD Blower

Who says Centrifugal is the worst of these setups?

That's all true. But for performance. Turbos will have more potential.

You have the Lag of a Turbo and the Parasitic drag of a Blower....

Really depends on the end use of the vehicle and how you like the power to be delivered, I have Data Logs of my old 3.0L Turbo car turning the 285 rears at 160 Kmh in the dry on a well surfaced test track... I spent a lot of $$$ to make it drivable ending up with DBW TRAC in the end, without it I got my ass handed to me by an old lady in a Corolla ;)

Not sure about the others, but i disagree with these two. Surely PD is easier on the driveline than a turbo?
And its much easier to install a PD blower than centrifugal as you dont have to worry about piping...

Blowers are cooler , tuffer :wave:

Mad Max had a blower, the blind guy in Running on empty had a blower, Dominic Toretto had a blower, o.k. bad example .

Say " it's blown " and the punters are ooooer, say " it's turbo's " and you think ricer, uncool, over use of bright green and orange .

Is this validated data or your opinion or some other persons opinion?

Haha, normally people with those sorts of blowers are the "look at me" sort of crowd. Id rather go under the radar, and watch them go "WTF" when i roll on past, lol

Would it have anything to do with a TT Kit being heavily marketed a few years ago but now has disappeared so we don't really hear about them anymore...?

I notice everyone is talking about TT kits, but no one has mentioned a big single. I tend to see more single turbo LSx's then TT set ups these days.

I wouldn't say no to either of set up myself, although i am currently looking at an intercooled centrifugal blower set up running 12psi

The "WTF" Factor shouldn't be underestimated :D

You're right in some respects. Going off my experiences with track days, on a day somewhere in the 20s or lower the IATs actually remain surprisingly low, somewhere below 40degC. On a warmer day they definitely suffer from the heat, but once moving the temps will still stabilise around 50degC, which includes battling a continuously rising coolant temp. I've done a max of 10 laps straight at Barbagallo and the only heat issues I've had were coolant temps
