what do you guys think... a supercharger or a turbo. pretty simple. and if a supercharger what type?

 

i know nothing about either except they add alot of hp and cost alot of $$$ too but when i get the go ahead from my dad, a vortech will be on my car

 

The parasitic nature of the Supercharger is a knock against it, but it's got better power-on-demand. However, with modern, multi-stage turbos and better intercoolers I have to give the turbocharger the nod these days. A well-built twin-turbo set up is just marvelous.

 

screw style blower is also a way cleaner install. You don't see 400 miles of plumbing to make it work

 

Theres a huge cost difference which is another reason most people opt for the blower route.

 

im a roots type myself. easy to install and and great power on demand like CineMax on Demand lol

 

Cost no object and complexity not a concern, turbo's get the nod, not gonna be able to out power them. Want something simpler and cheaper to install, go with a supercharger.

 

Yeah it really depends on what you want. If you are looking for big power, then turbo is the way to go, like others said...more costly.


If you are going SC then a roots or screw type SC is the way to go. Very simple. power from idle all the way up.

 

Turbos if cost is no object. For most street applications and budgets the blower will generally win every time.

 

I think even the single turbos these days are great. Very low boost threshold and lag.

I'd go with a turbo (depending on how your car is used). I had a twin screw supercharger (Saleen) and the torque curve was boring.

I've heard that the heat generated by a turbo can be very problematic on a road course.

 

There's decades worth of racing Porsches which would disagree with this. The only reason it would be a problem on a bolt-on is becuase the person(s) who installed the system didn't do a thurough enough job upgrading the cooling system.

 

True, but I think most people just want to buy a "kit" and be done with it. Correct me if I'm wrong, but most Mustang turbo kits don't upgrade the cooling system and are mainly designed for steet driving / drag racing.

 

you are correct. If you were road racing you might want to put a better cooling system in regarless.

I'm sure you could put some heat wrap on the exhaust side of the turbo you would be perfectly fine.

 

Cost aside, for me I would choose a well designed turbocharger system all day long and twice on Tuesday! A TT V8 Mustang is where its at.

 

turbo's are priced pretty close to the s/c

 

i really prfer naturally aspirated motors. think about it.
say you got a 400 hp N/A 5.0 and a
supercharged/turboed 400 hp 5.0
If you but the naturally aspirated one it is easier to put a supercharger on it and have 500 hp vs having to up the boost on the stock supercharger and run the risk of the internals failing

 

Before I got into Mustangs, I've generally thought most twin-turbo setups involved one giant turbo (for ridiculous boost) and one small turbo (for boost while the big one spools up).

With our V8, it looks like that option (or even single turbo) would be alot more work, because we naturally have two exhaust lines... and it looks like twin symmetrical turbos seem alot simpler than different twin turbos or a single turbo..

I'm new to this. So when you guys are referring to "twin turbo," which kind of "twin turbo" are you guys referring to? Any words on advantages/disadvantages?

 

NA only goes (practically) so far though. If you keep pushing and pushing, the car will have very poor driveability characteristics.

That's the great thing about FI. The car drives like stock until you get into the boost.

 

From a production and do-it-yourself standpoint we're talking parallel twin-turbo. You use two identical small(ish) turbochargers (one for each exhaust bank on the V) which spool up faster than one large (cutting down lag), while still producing alot of power by their combined action. Add in modern turbo tech like variable geometry and you can have a pretty devasating setup with minimal complexity.

Sequential Twin-turbos use a two-stage setup where one small turbo runs all the time and a second only kicks in at high RPM for top-end. Problem is that you have to plumb all your exhaust through both, which is a minor nightmare. Racing machines and exotic can pull that off, but not regular production cars or home conversions.

 

Also, generally any engine cranking out a lot of NA power would have a high compression ratio, to run boost you need to lower the compression (or else...). So its not like you can take a real wild NA setup (say 400hp 5.0) and just strap on a blower running the same amount of boost as you could put on a 225hp 5.0.
