Turbo vs Supercharger

anybody??

 

Well I am not aware of any specific kits for either but it all depends in your application if you have a lifted truck chances are you will want to go supercharged. Instant power when wheeling is the way to go. Turbo is great for high HP applications and drag racing go turbo. The problem with a manifold supercharged setup is heat but with the proper cooling mods (heat exchangers meth injection ect.) you can make it much more effecient... my question is what is available after market as far as injectors and what not for the 4.0L as well as turbo kits and other available supercharged set ups

 

check on http://www.urdusa.com

 

because turbo'd toyota tacoma almost rhymes. and turbo lag is easily minimized with a proper exhaust system that allow high flow giving you a much wider power ban and give you the option of higher boost but if you really wont my opinion you need NOS. . . "too fast, too furious"

 

heard that the sts have problems...

 

i want to supercharge mines. dont really like turbo for trucks to much work also haha.. like the oil lines and stuff and it wont probally pass smog. supercharger will... hehe less work for me..

 

I drive a turbo charged VW diesel and I love it....but having said that you should concern yourself with the kind of intercooler you should buy with it to keep it cool. The VW uses a Side Mounted Inter Cooler (smic) and it's hidden away so no one will see. That's kind of nice. Next you should see if your xmsn will take the power and lastly what will it do to your rear end. Just be ready for those little mods followed by a beef up clutch. Good luck.

 

well, when urd finishes the kit, im definitely going to look for that. wouldnt a frontal mounted intercooler be more efficient at keeping it cooler vs a side mount?

 

Most definitely a fmic would be better but there is so much plumbing that comes with it and the engine bay in my jetta is very small so i try to optimize everything. I have chipped (programmed) my engine control unit and am not pulling about 50 more hp but i've already gone thru one turbo and i've been told to take it easy on the xmsn. it's not built for that torque. Same with the rear end. If I had a clutch I would worry about that too but i'm an automatic. The other blog i go to talks about diesels and inter coolers. My basic take on sc vs tc is where the air is heated. There are many intercoolers out there so shop wisely get into the blogs and see what everyone else says is working....i'm upgrading my smic with a tyrol smic. i told it will help....

good luck wish my truck was as new as yours but i'm waiting on the diesel taco...then i'll buy again whether i need one or not....LOL.

 

take your taco and stick a diesel in it, or there is a company that does the conversions. be cheaper than buying a new one just for the diesel

 

Your Jetta has a 'rear end' ?

 

Its not so clean cut for applications as "turbos are for small engines and SC's are for big ones"

Turbos, while they can produce gobs of boost, are peaky and the bigger you go, the more lag you get. Turbo lag being the time it takes for the impeller to spin up to the 80,000RPM it takes to make decent boost. Things you have to watch for in being that turbos impart TONS of heat into the cooling system being cooled by the engine oil, and if not tuned properly, things can get wonky a bit faster with a run away turbo. But at the top end, say 40% rated RPM and above, they are hard to beat.

Superchargers, they produce power everywhere. They're smooth and fairly hassle free. They aren't cooled by the engine oil/water and are pretty damn reliable. Drawbacks being that to change your boost, you have to swap pulleys...and on the TRD unit for the 4.0 its hard to say the least. Supers make boost from idle, so you never get a suprise rush of 80 extra HP, making the vehicle easier to drive if you lend it to anyone.

For a truck you're not intending to live on the track with, I'd vote Supercharger. Just less hassle. You just have to think honestly about the kind of driving you do on a daily basis.

 

I will agree that superchargers provide a more 'convenient' package for the DIYer. However, I have to disagree on two of your points. 1)A turbocharger will transfer a marginal amount of heat to the system as opposed to a supercharger. There just isn't a lot of heat transfer between the turbine section and the cooling/oil system of the vehicle. Also, I would estimate that with both systems 95% of the heat is introduced via gas compression. 2) To say that a turbocharger would only become effective after 40% of the power band is a generalization and does not apply to all turbocharged systems. As I have said earlier, systems should be optimized for specific goals. If your goal is to have on-demand torque from 0-2500 rpm, a turbocharger can be sized to provided sufficient flow rates at low rpms. In such a scenario, you will find that flow and efficiency will fall off air consumption increases, just as the case of many superchargers.

 

I read these S/C vs TC often and the question really comes down to "How mechanically inclined are you?" I consider myself pretty far along and the Turbo is a huge increase in HP over the Super but I did not want the tuning/ routing/oil lines and such. I also really dont want to have to Fab up the the heat exchange mounts and bend tubing for the boost.
The super was straight forward and made a huge difference in the way the truck responds. Some days I could want more other days its just fine and the fact its my DD makes the Super the win.
I don't have any leeway for downtime. Once installed you can tune away if you have the piggyback but other than that I know its taking me to work the next day.

 

That's is exactly my point. Superchargers are fantastic if you want something that will install in a weekend and give you low to moderate HP gains. I've had both factory turbocharged vehicles and vehicles I've added turbo setups to. With an aftermarket turbo setup, there is a lot going on and many more points of failure (not the best thing for peace of mind). A supercharger setup does away with many of those 'reliability inconveniences'.

 

umm id go with a turbo bro suopercharger costs a bunch of money!

 

This thread in it's 9 page entirely could be summed up in 2 lines

Supercharger for Off Roading
Turbo for Racing

Done!!!

 

And that would be wrong on two accounts. You cannot generalize turbo vs supercharger based on your criteria. Hence the 9 pages of discussion.

 

You can when the application is specific to Tacomas.

 

Wrong again. If you had a mildly modded Tacoma with suspension lift, tires, etc. A supercharger would be a fantastic option for off-road use. But if you had a bad ass trail rig with suspension, big tires, atlas transfer cases, etc. you will be operating in the upper portion of your power range, thus better suiting itself for a turbocharger application.
