I'm thinking about doing a battery relocation to the trunk and opening up the engine bay a little bit while freeing up some weight up front. I don't plan on going with any aftermarket intake, but I would like to run a stock EvoX intake system on the Ralliart, might have some gains compared to the stock Ralliart intake.

Thoughts?

 

Why not just do this?

No tune required and you don't even have to relocate if you decide not too.

I'm confused as t the point... Seems like a lot of work for no real gain.

 

That's why I'm asking opinions, maybe someone has done this and has seen a difference. The way the intake design differs from the Ralliart might be helpful since it would be a straighter path of airflow.

Just an idea.

 

Oh, I follow now. I think the general consensus is the Ralliart Turbo just doesn't flow enough to need an intake design change. Hence the reason people don't really see much of any gains with a tuned RA vs a tuned RA w/ intake. The stock intake seems to flow just fine for the stock turbo. The turbo is the bottleneck, not the intake. Anyone is free to correct me if I'm wrong. But I doubt you'd see any real gains.

 

^ what he said.

 

Meh, the DIY SRI for $70 is nice though, you get to hear your BPV and hear the air being sucked in :]

 

My opinion:
Function > Form.

Only non-functional thing on my car is the AEM Intake. Had I realized sooner it wouldn't do crap for me I'd have bough something else.

 

Not only that, a SRI for a turbo'ed car isn't the best idea anyway. At least with the stock intake you're taking in cooler air as opposed to the hot air in the engine bay.

 

not sure if you noticed or not; but almost all intakes for the Ralliart are SRI intakes... except for injen CAI for our cars and Evo x...

I do get your point about the CAI but SRI does not matter if you get tuned with the intake. I think CAI are best for N/A cars.

I could be wrong; but yea.

 

Are you serious ?!

^+1

The majority of intakes for Turbo'd cars are SRI because the intercooler is what is cooling the air prior to entering the car. I did the SRI because it does allow for better airflow, a cheap, effiecent mod, that we cant begin to calculate if it is or isnt worth it. It is up to the person who has the car... I personally liked the sound, and eventually was upgraded the turbo so i did need to do it. Some other may not care, for whatever reason, so they dont do it...

 

Relax, I'm new to turbocharged cars. Forgive me if I get something wrong...

 

Besides, I'll learn a little more about how the intake and intercooler system is routed once I go to replace my IC and piping soon.

 

Right, but starting with hotter air means your still going to have a bit warmer air after cooling depending on the IC. The stock IC on the RA already has trouble, giving it warmer air is a bad idea.

Somewhat. Just replacing the intake is pointless, tune or no. EvoScan (with virtual dyno) can prove this. In fact on the stock RA IC, a SRI will do more harm than good. However, in your case it makes sense, as you were going to a bigger turbo that can make use of the extra air. This is the one thing that makes my AEM worth it, is I plan to move on to a larger turbo and the AEM will *hopefully* feed it air better than the stock intake would have. Now if $70 is worth a noise to you, then ok. I personally don't think it is, and for a bit more you could get a better bpv that can do 90% recirc 10% VTA and get even more noise and also be replacing a part that actually has issues.

 

Let me know when you do that. I'll happily help. That lower IC pipe can be a *****.
