3.1 MPFI COLD ram air intake! No Battery relocation!! 92 Cutlass

i honestly don't see the point of putting the air filter where it's gonna be a bitch to change it later. like behind the battery...i wouldn't want to disconnect my battery or have a bitch of a time taking the wheels off and trying to get the fender wells off to change it or clean it. with the air filter sitting low like that, wouldn't the air filter get dirtier quicker, making it lose performance? the air going to the engine wouldn't be any cooler sitting between the radiator and the exhaust manifolds. especially where the cooling fans pull the hot air away from the radiator. plus plastic melts and breaks.

That intake is junk, sorry to say man... But it is gonna cause more problems than it is worth, especially since it looks like you hit up AutoZone for some Spectre plastic intake pieces. Heat soak is the worse of your problems, then other, is the fact the bends are causing it to be more restrictive than the stock

 

The bends won't hurt it a bit. In fact, intake piping LENGTH has a lot more to do with power production than anything else..........and the longer the pipe, usually the MORE power they end up making over certain sections of the powerband due to resonance supercharging.

 

Basically, as long as you don't have right-angle (or tighter), NON mandrel bends in the intake, power production isn't going to be affected.

 

 

 

Next, heat soak.........

 

The filter is still picking up a "cold" (not so much on a hot-ass day, but there you have it) source of air. Sure there is 30+ inches of piping winding through the engine bay, but at WOT that amount of piping will empty of air in a VERY short time...........as in less than a SECOND.

 

The IAT temps *might* go up a touch from radiant heat soak, but we are talking a COUPLE of degrees here at best.

 

In other words, as long as the air SOURCE is out of the engine bay, he's good to go.

 

 

 

 

 

Finally.............hydrolock.

 

Yes, it's a possibility (as it sits).

 

But my fiancee's Neon R/T has an Iceman CAI with a VERY similar filter placement (over closer to the driver side though), and it has been run through numerous rainstorms and 4 Iowa winters now, INCLUDING a number of instances of PLOWING through deep snow.

 

And her car is just fine.......

 

In addition, there are MANY aftermarket products that help stave off hydrolock..........the AEM air-bypass-valve comes to mind, as do Outerwears pre-filters (I have one of these on the Neon since after it's first snow-plowing experience).

 

 

 

 

Either way, *I* fully think the thread originator's CAI design is actually VERY viable, and as long as his pipes don't melt from the front manifold, I say more power to him...........

don't go to 3 inches. it's too big. you'll be slowing down the air velocity. plus your maf and throttle body aren't 75 mm, which is 3 inches.

 

It's not an exhaust..........intake air velocity doesn't matter much at all until you get PAST the intake plenum (intake MANIFOLD runner size DOES matter).

 

2.5in IS probably enough for an MFI car as they don't breathe worth a shit (especially past 4800-5K rpm), but a Gen III 3X00 DOES do better with the bigger piping.........especially with the big 70mm MAF sitting mid-stream on 96+ cars.

 

3100's, just need a little bigger TB.........mod a 3400 (LA1) TB and match your plenum inlet...........it's a $20-40 part from most JY's plus a little work with a die-gridner or dremel..........sure it doesn't make much power (likely 1hp or less), but for the price...........................
