Default intake

Just so you know, i plan on getting a K&N filter, so with that said don't you think with a good heat shield on the crossover pipe and one on the filter would be ok. What would you suggest to get a good intake on there. As i said i have considered relocating the battery so i could run a rice pipe and box in the cone there. I do know that it is better than the stock air box because i felt a pretty noticeable difference when i changed it, but i just want to get the most performance out of it as i can since the options are more limited on the l27. Thanks again and sorry for being a pest on this issue, but i am just looking for a little friendly advice because i have been thinking about this for awhile now and am not sure if relocating the battery would be worth the trouble.

To reiterate, this statement says it all:

Not only that, but you want a 'long-ram' intake tube to develop velocity and laminar flow. This isn't as important on the supercharged engines, but it is on your L27.
While we could go into great detail and argue about your previous positive results, etc., the bottom line is that you will need to shield that intake air from ALL engine bay heat if you want to reach your stated goal of getting all possible power from that L27.

Additionally, the mention of velocity and laminar flow above is the result of much research and testing done by folks on this site and not just a casual thought.

You actually mention above that your results get worse after the engine gets to temp. That right there, tells you all you need to know, IMO.

Keep us posted as to what you end up doing and your results.

I kinda already figured it was gonna take moving the battery. I guess i just wanted to hear some opinions on it because of hearing that the shorter and straighter the better. So it made me think, colder or shorter, but i think i already knew the answer, after all it is called a cold air intake. Thanks again for all the input and if there are any suggestions on building some kind of custom intake for this please let me know. Aside from all this check out the rest of my regal at the link below and see what you think of the rest of it..Hopefully you like it more than my intake.

Can we get a larger pic shot from directly above as high as you can get that shows the entire engine bay?

Nice looking car! Seems like you take really good care of it and have kept it super clean.

I don't think anyone intended to dis your intake set-up, we have just had some collective experience and know what works and which things might not be as good. Believe me when I tell you that most of us have done things that didn't work out as well as we had hoped. That'* part of how we gain the collective knowledge.

Keep up the good work!

Wow, that IS tight in there!

You may have to just relocate that battery as you mentioned above.

OR.....

You could go wild and crazy and...

put a hood scoop with direct feed on that side and a dummy hood scoop/heat vent on the other side to match, lol. :P

Just thought I'd lighten up the mood.
