URD supercharger for 05+ 4 bangers?

and I really won't. I was more trying to make a point that it's just easier to start with the 80mm over the 85mm. Saves a step.

 

yeah i would rather just get the kit sent with the 80mm pulley too since i would end up buying it anyway, i also have LCE headers and would just assume take it and get it tuned on a dyno. Not every motor is exactly the same anyway, if you were to dyno all the guys motors in this thread, stock vs. stock, bolt-on parts vs. bolt-on parts, you wouldnt get the exact same numbers. I know the tune that Gadget puts on the ecu will be very well tuned but you never know basing it on individual motors especially if you have headers and exhaust.


Ill probably spend the extra $200 for an hour on the dyno and the satisfaction that i know my exact numbers, not just basing them off the dyno chart on here, and that i know it is tuned specifically for my motor and to its full potential!


Gadget, you say those numbers are on roughly 10 psi, do you recommend running 10 or is 8 more in the recommended range and your taking a chance running 10???

 

Or know a guy that doesn't even bother to pop the hood when smogging...

 

Or live in a state like Alabama where we have no emissions testing whatsoever, let alone garbage like CARB.

 

You took the words right out of my mouth. And besides he wants the first ten to go to people in the area? Say I'm ready to buy now, I would have no choice but to go to a speed shop and have it dialed in. I personally want to run 8 psi until after market valve/cam/piston kits come put. 10 psi is no bueno on these engines, don't care what anyone says. They are not as internally stout as even smaller 2.0's that say Mitsubishi puts out. This kit is great but as a 4 cylinder community we should be taking baby steps with boost.

 

Um. Wow.

He said it'd be nice for the first few to go to people in the area so he can verify the tune on a totally stock truck. I don't believe he was going to refuse to sell you a kit?

You would have no choice in what way? It's set for 8psi right now. Buy the kit.

And lastly, on what do you base your assertion about 10PSI? I'm not even saying you're wrong, just that you're making random, erratic, baseless statements dude...

 

That's mostly just me thinking out loud. I'm not here to bash on URD, just making an observation. I know it's a preference to where the first 10 are sold, and that it doesn't disqualify me, but I'm just playing devils advocate for people that may read and won't post what's on their mind.

If there is an 80mm pulley I would have a choice. He (Gadget) stated he would make the 80's available after a kit has been tuned w/ an 85 (which we have covered).

And the assertion about 10psi (again) is thinking out loud. This wouldn't be my first rodeo with boosting a 4 cylinder. What I am trying put out there is that the 2TR is not technically a boost ready engine. While it is a great platform, it's just not ready for a constant 10psi or greater boost pressure. Yes to an extent it will handle it with no issues, but like always shit will pop up, and believe you me, people will bitch because they didn't know what they got themselves into. When LC Engineering starts making beefy after market internals for these blocks, I'm all for 10, 15, 20 psi of boost. Again, only thinking out loud, this is not an attack or an attempt to discredit anyone's work, or knowledge.

 

Even the stage 2 kit is not 10PSI constantly, that's peak. Unless you floor it literally everywhere you go... It's probably half of that in regular driving.

And I'm guessing he wants to sell the 80mm pulley and tune as an upgrade, as he does with the v6. Because he does this, you know, to make money.

 

Just a question out there. What's the expected gas mileage after u install the supercharger kit??

 

Not necessarily true. If you floor it everywhere then yeah, your mileage will take a huge dump.

But supposedly if you drive on an even keel, you shouldn't see too much loss and may even see a benefit in highway driving (since you now do not have to downshift + you gain increased engine efficiency with a blower in low boost.)

So apparently, like everything else mpg-related, it depends on the driver. I'll be taking my truck on a 2-hour drive Sunday, and I'll report with an idea of what I see with highway cruising.

 

Im just saying. The truck is my toy but just wondering what the expected gas mileage is going to be

 

as much as your right foot will allow, if you drive normal, you shouldnt see any changes, if normal for you is sideways full throttle around every corner then you'll see a significant drop...

 

Sounds good. And tell us how much of a differnece it really makes with the superchrager. I know its already making a difference with the dyno chart gadget put up, but in ur personal opinion how it feels with that kit underneath the hood. XD

 

Dude I'm gonna post video in my build thread for this one, for sure!

(Otherwise my buddies back home will kill me, they're about as anxious to see the truck as I am.)

 

Hana im pretty sure they will. XD ill also be waiting for the build thread also. XD

 

We'll see what I actually do. I suspect I'll floor it for the first couple weeks, and then I'll go back to driving like a sane human being.

Premium does not help my gas mileage, been there and tried that. If I see an increase, it is not premium gas, it is that I can actually go up a hill in fifth without having to downshift and go to 3,000 RPM (despite the fact that fifth now inherently uses more gasoline thanks to the supercharger).

An additional note that may skew the results is that I got 19-20 before, but that was with a clogged cat. So having that fixed will certainly help by itself.

 

Just to be clear too, I obviously didn't throw on a blower for the mileage! I'll be very happy if I can get 20 (hopefully 22, like I said, fixed the cat) highway out of it like I did when I first broke it in. I thought my decrease to 19-20 was because of the tires, but apparently maybe not.
