supercharger questions

Use a smaller pulley for bigger boost, not a larger one

 

Who says the URD kit won't have an intercooler? Mine does.

And it's a Rotrex, not an old-school centrifugal. As stated before me, the rotrex design eliminates many of the issues with centrifugal blowers.

You're clearly not up on what you're talking about, dude. Please stop spreading misinformation.

 

W/e, you knew what I meant .

I wish !

I didn't say it didn't have an intercooler, I said I dont think it had one and would probably need one.

The TRD will still offer better low end boost IMO. While the Rotrex design will give a better power curve in the higher RPMs, your engine is designed for low end torque, not high end HP. Your max engine output is at 4800 RPMs and your redline is below 6k. Unless you do some heavy interior engine modding for better breathing and higher RPMs, you're not going to realize the max potential this charger has. It will be hell on the 4.0L and def a good buy for the X-Runner, but for off roading, Im sticking with the low end torque roots style charger.

Its not miss information, its my opinion .

OP, before you do any supercharger modding, you should read this: http://www.ultimateyota.com/index.php?option=com_openwiki&Itemid=60&id=wiki:trd_3.4l_supercharger

 

Yes, but it does have one. So you're making baseless claims as points against the URD kit. I don't particularly care whether the OP chooses TRD or URD, but he shouldn't do so based on your "opinions" that you present awfully factually. Quit it.

Again, you're just blatantly making shit up. They both go quite fast, and Gadget does a hell of a job making a supercharger kit. OP can compare dyno graphs. Stop talking.

You're presenting your random musings as fact. This is asinine. Quit it.

 

Although you did post a helpful link. Some comments:
- I have no idea if the URD kit has the same pinging problem.

- The URD kit will probably have a new fuel pump, obviating the fuel delivery issue, based on what Gadget's other kits look like.

- Ditto for fuel injectors.

When comparing costs, I'd bear in mind the cost of fuel injectors & a fuel pump, as well as an intercooler and plumbing for the intercooler.

 

if you're at 100k you should do a leakdown test and compression test first

 

Why are you posting on a 1st gen question when you are running a second gen URD anyways? Great, Im glad you like you setup. Im sure it does wonders for your 4.0L. I personally dont think its best for the 3.4L. Structure your arguments in a civil manner or please or GTFO.

Again, its my opinion and Im sticking with it.

OP, here is another nice build thread on the TRD FWIW: http://www.speedysgarage.net/sportr.../projectsportrunner_trd_supercharger_blog.htm

 

I have a 2.7L, chief.

 

btw if you dont upgrade the valve body you will have your transmission die

give these a read, I wouldnt get a supercharger unless you get this

^^^ THIS IS GADGETS WEBSITE! ^^^ thats why it says gadget online.....

 

And furthermore, I'm saying that a lot of the things you're saying are bad about the URD kit are most likely completely false. Despite being pure speculation, you're presenting your opinions as fact. And this is blatant misrepresentation.

Based on my experience with my 2tr-fe, Gadget will give you all the components you need for a turnkey kit that will make up for stock issues. For whatever reason, most likely cost, the TRD kit does not appear to do that. (no intercooler, no injectors, no fuel pump.)

Factoring that in, to me, makes the kits much closer in terms of cost. Dynos will dictate performance, but I'm willing to back URD on that one, too. The OP can get whatever he wants, but he shouldn't be swayed by bullshit arguments that "rotrexes need intercoolers so you'll have to buy that" (when all other urd kits include an intercooler) or "rotrexes won't make any power down low and you won't get the top end performance out of it because of the engine design" (when the URD 4.0L kit clearly outclasses the TRD variety.)

You don't know what you're talking about, pure and simple. If you had reasoned, valid points, fair enough, but you're spouting off shit like a TRD fanboy, and it's aggravating.

There are definitely drawbacks to Rotrexes vs roots-type, nothing in this world is perfect. But you're not elaborating on valid drawbacks, you're talking out your ass.

 

Probably. The ping was not due to the Supercharger but the ping sensor on the engine. Its easy to get rid of with proper tuning. The URD 7th gen injector set is def a must. Better and cheaper than the TRD.

Where is Chris and his bag of popcorn when you need him...

 

I'm guessing you're not planning to dump $5000 on a SC for this vehicle to get groceries and pick up grandma, so I'd say a LOT more wear and tear...

If ANY of those parts fail, don't expect Toyota to help you out (as I'm sure you're aware)...

 

Albeit all the first gens are way past warranty anyway?

 

How late is to late to put supercharger on engine? Like is 70K to many miles or is 100k to many???

 

My '04 isn't, but barely.

My point is that no matter what year it is, and you add another 100+hp, it doesn't matter what the warranty is.

 

Wait for the warranty to expire, then you have no worries anyway.

Just remember that with mods like this, you likely won't get to the 300K mile club...

EDIT:

This is because of heavy foot syndrome. Most mods to engines are "efficiency" mods, in that all they do is make air/fuel easier to get in/out. As a result, you get more power, but it's technically more efficient, too. Example: say you get headers and a K&N cold air intake. Those will increase your mileage, unless you're a man, and like the new sound your truck makes, and like making it make that new noise often. THAT will kill your mileage, even though it's technically more efficient...

 

sounds to me like this post is spewing a whole lot of the same shit you're accusing others of...

just sayin'...

 

ok.
