Turbo or supercharger?

[merc85]

Yep Ive had loads of Turbo'd cars and my Supercharged e55k, Turbo's for me as i like that Shove you get, With Superchargers It's alot smoother and they dont seem tobe as quick "although" they are.

Bi-Turbo 63 for me anyday.

I've got a soft spot for an SR20DET with a disco potato.

I found the standard one horribly boggie off the line. So I got another one and chucked an HKS induction kit and cat-back zorst on it. The lag was gone

That's old tech of course. These day sequential TT's are the way to go.

I'd happily have a V6 3.0 TT as a more efficient alternative to my current V8.

You can't beat a V8 for sound, really, and the problem with turbos is that generally they spoil that. Modern high-performance turbo engines, particularly aftermarket-tuned ones, just don't cut it for me; reliable, powerful, economical they may be, but what comes out of the exhaust is mostly noisy, ugly, raspy techno-farting. It's not about how much noise, it's about the quality of the sound.

Whereas I associate the noise of a V8 with "all show, no go"; I remember how much fun it was destroying the V8s with a Skyline GTS-T. You let them pull alongside, wait till they start making lots of noise then spool the turbo and leave them behind.

I've had cars with superchargers and ones with turbos. With the exception of the biturbo diesel in my Volvo, neither type has been cutting edge - Rootes in my XJR, single turbos in various petrols and diesels. Lag was not an issue on the XJR, but the supercharger consumed 100bhp - that's an immense load on the engine. I can't say I particularly loved the whistle of that or my C32AMG. However, for classic car sport, the sound of a supercharger at chat is tremendous. Recently I attended a talk from Mac Hulbert who had owned the famous ERA R4D. He used a mild supercharger as the period one (mounted in the footwell) had a habit of blowing up and he valued his nether regions too much. He said the engine (a 2 litre twin cam derived from a Riley) would produce 300bhp without a supercharger and 340bhp with (this is a light 30s car - the acceleration is phenomenal). Alpina used a nautilus style supercharger on their B5/B6/B7 - it only uses 20bhp and spins at 105,000 rpm at 6000 engine rpm. Problem is, it's had clutch issues so they have subsequently reverted to twin turbos.

Old technology? Nissan were using sequential turbocharging in the '90s RB26DETT, and the March had a twin-charged (super/turbo) 900cc engine. - It's just the turbocharger that've changed (none of those delicate ceramic wheels these days).

Is the 26 the Skyline engine?

My S14 200SX's just had the one blower. And intake and exhaust restrictions which stopped it spooling up properly below 1500 rpm. Fine on the open road, a PITA in my commute at the time from West London to Feltham.

Still a great car overall. Grunty, sophisticated suspension, LSD with it's own little oil cooler. Loved that last touch.

NA, like M156 for example, yes. FI V8 - another matter.

Quite possibly, but I wasn't referring to performance. The V8 sounded better...

V8? Super charged? Nice sound?
Try this, it's the last supercharged car I have run.

It was good enough for a podium finish, but did run out of breath at 14,000 feet! 'Only' about 400bhp up the top.
That elevation is not too much of an issue in the uk
Hope to go back next year with a turbo car and almost 900bhp. That should make the straights a bit shorter

It sounds a lot better from the inside, doesn't it? THAT's what I'm talking about.

I was left standing at the lights by one of those in a hurry the other day. Fast? Unquestionably. Noisy? Unquestionably. Sounds good? Not nearly as much as it's fast and noisy...

Had four turbo 911s (930/996) plus a UR Quattro and I really liked the noticeable shove as the turbo spooled up and the torque and power came in. Superchargers are fine (I have a cls55) but use quite a lot of power to drive and to me at least, give an experience thats nowhere near as explosive.

 

[AMGeed]

Only had one turbocharged and one supercharged car so not too much to compare with.
The superchipped and turbocharged Cossie was very much either on boost or not and nowhere near as smooth as the current S/C E55.
But modern turbocharged cars have eliminated the dreadful lag and on off switch feeling and I'll happily have one next time out.

I loved the on off nature of my old Cossie.

Sorry, I mean that sequential turbos are not new technology. - Despite what VAG might have you believe, neither is super/turbocharging an engine.

If you've been watching Drag Week, it seems that twin (not sequential) turbochargers are the favourite power-adder at the moment; although I think it was a 6.2L supercharged V8 that won overall. - The (stock) CLS63 was pretty far down the list with an average ET of 13.4s compared with 10.0s for the winner of that class (street machine eliminator).

The sound of a whining supercharger is pure bliss!

My Mini Cooper S (BMW) supercharged is a hoot and not many 1.6 ending sound that good when being driven hard.

Superchargers give better/easier mod options but fuel economy and ambitions are a problem

Lag......whats that all about

 

[AngryDog]

Very tempted to chop the E55 in against some turbo hot hatch for a bit of fun.
