TRD supercharger

The amount of boost lost probably won't be measured on the gauge, you're talking about 1/10's of a psi. As stated on other vehicles it has been proven that they lost 5-15 hp. Which is very minimal if you feel the need to drive through water. But as far as which snorkels are better for the s/c no real research has been done. It's all just hear say from people trying to push one brand or another's snorkel.

 

Then show me documented proof that a Snorkel can be plumbed safely through a CAI box and a Supercharger with zero boost issues

 

I guess I could dyno my truck again, I could take off the snorkel, dyno it, then reinstall the snorkel, dyno it.

 

You have a 4cyl that is 1.3 liters smaller than the 4.0 with a blower that puts out less cfm's. It's also run through a stock air box and filter. As I stated on a stock 4.0 with a m90 blower running all stock components you would more than likely see no loss. It's once you open up the intake, exhaust and start spinning the blower faster that you will see losses, which will still be minimal. im still waiting to see proof that one snorkel performs better than the others or homemade ones like @sytfu510 if you ask me his is still the best looking and probably the best performing if he got rid of that junk corrugated hose 4.0's use. It's funny to watch one person post something on these forums with no proof to back it and then watch 50 people recite it as if it fact because they want so badly to believe

 

Like I said, I'm not knocking snorkels. If you want to drive through water than a small hp loss would be better than hydrolocking a motor. Plus they look super expo

 

I'm not even sure who you're accusing here? But so far there's no actual proof of what I'm asking, just hearsay as well

 

and like @glorifiedwelder said, @mahaloTaco 4 banger with a stock box....not what I was asking. I'll reiterate...for those of us with the V6 and aftermarket performance parts and increased boost...can you run (well say Airflow because of largest OD) the Airflow with say an AFE CAI. I believe the Airflow has a 3" OD? Whereas the AFE CAI has a 2.25 OD from box to throttle body, which is a restriction. So I have heard of people saying they saw their CAI box getting sucked in a bit under load because of to much restriction. Again, hearsay, but I'd rather not hook it up on "I did it on mine and it worked" and fuck something up. If we get a couple bodies that have different but similar setups with snorkels post some videos to banish the questions, then I don't see any issues. But until then, the 'loss of boost' 'story' is going to remain in the loop.

 

I'm not accusing anyone if I'd was I'd have the balls to tag them. I'm actually agreeing with you, which is a rare occurance. Lots of stuff has been said in for sale threads reguarding s/c's and snorkels which has no backing. It's just sales gimmicks. I haven't addressed them there because I wouldn't want to shit on a fs thread or group buy, but once it's brought to an informative thread I think it should be discussed.

My last post was describing how dynoing a supercharged truck making about the same horsepower as a stock 4.0 really doesn't tell us anything about the performance of an upgraded s/c truck with and without a snorkel

 

Agreed.

 

I agree with you that no testing has been done and even with a snorkel the same diameter as the intake you are still adding more bends and places for turbulence to build in the intake system. I have no interest in running a snorkel but would love to see a dyno done on the same truck running different intake setups with the snorkel and without. Personally I think it needs to be the same truck though. When I used to spend a lot of time at the dyno with customers race engines I had built, you would often see the motors with the same setups have variations in power between the two. Some were more Giftes than others. If the same truck was used we'd get consistent increase numbers otherwise we'll just be comparing percentages between different setups since all trucks will have a different baseline.

 

Wut is happening here

 

Right? @glorifiedwelder , Did you and I just have an agreeable conversation? What just happened here.

Well, its nil for me as I'm running the URD intake now, but I am considering modifying it with an exhaust cutout and an in line filter so that i can pull from both but switch to just snorkel when in a water crossing or high dust situation. Only issue now is where the MAF is located. Wonder if I can move it closer to the throttle body and not have much turbulence.

 

Would a dyno on a snorkel show real world results. Dyno is stationary and not ram air like a snorkel would do going down the road

 

I think you are sucking in more air than is being rammed down the tube, but we would need wind tunnel testing to determine how the snorkel functions aerodynamically. I think if that was a performance gaining factor you'd see it employed in more race applications

 

Thank you! That's another one that everyone throws around but I have yet to see proven. The 'ram air' effect that is so much better...

 

I think math based on capable CFM flow of the parts, would also answer the question. I'd rather watch the GoPro videos of the air box though.

I do remember someone talking about their snorkel causing a noticeable amount of lost power. Until perhaps they changed its filter/opening??? Maybe it was @NYCO ?

 

Wish I still had my AFE box, I'd go throw a quick 3" PVC pipe on it and drive around the block just to test.

 

wasn't me...luckily the Airflow has same diameter tubing as OEM intake...i can see maybe an issue with the older style Safari snorkels...

 

Well shoot. Thanks for answering as well, Nyco.

 

Now we just need to compare the oem diameter to the aftermarket intake diameters
