Hello,

after looking at how the intake runs in the stock LS460 on the 1ur-fse, couldnt you run a different style intake? Is there any benefit to running Single outside ram, to dual intake/filters on top of a hot engine, back to a single into the TB? How would a single aluminum pipe with large filter work? shoddy image for reference, either running a intake elbow with filter going left, right, or even straight forward, with help from modifying the current ram air to feed said filter? Any opinions welcome.

 

Using a single MAF sensor would be simpler but I wounder if Lexus struggled to develop a filter capable working with single intake port.

I just think there is not enough room in the engine bay to run that single filter like on the 400 and 430. The air actually takes a longer route to get to the engine. There's a lot of stuff crammed under the hood.

 

I was thinking along those lines too, though I did not know about the specifics 400 and 430 air intake systems. Ultimately, what matters is the distance between MAF sensors and combustion chambers. On other side, longer intake system causes higher air flow reduction, especially, at the bends.

 

Here's a mock-up pic that I saved a while ago when researching this topic. Perhaps it will serve to provide further clarification/ideas for this mod.....

 

I think, a good place for filters would be behind front fenders. It guaranties ambient condition air but makes a replacement harder than it is.

 

On the 98-00 400 and 430 the filter is sitting behind the passenger headlight. The air comes in above the grille then goes to the right and come back to the middle into the engine. I can't remember if the 95-97 400 takes the same route but on the 89-94 400 the intake enters into the passenger side of the engine.

 

For comparison sake , the LS HKS supercharger intake route is super long. Keep in mind that the charged air still go through a air-air intercooler.

 

Also deleted the intake resonator and went straight pipe w muffler delete. It actually roars like a v8, the throttle response is bananas

 

Bro, explain this to me like im a 5 year old, i understand some but please elaborate, the part when you deleted intake resonator
thank you

 

Wouldn't you pull hot air from the engine bay using such air intake? OEM setup gets air from outside of the engine bay.

 

Really sweet! Did you design and build yourself or have a shop fab and install for you?

 

Would love to see IAT temps .
