My J's Racing Intake Installation...


Thats great jugbugz. Thanks for the info:).Keep me posted as to what way you decide to feed the short ram with more cold air :nice:

Think about it the same way as the intake manifold, one with short runners like the type-r is more optimized towards high rpm than one with long runners like the b18a1. (although advances in design have proved this theory less relevant with certain IM's)
I'm using the comptech ice box.
Way2fastforu the only way to be sure of where each intake performs is to do dyno testing with both intakes. The v2 may feel better than the J's because it has a cold air source, the short ram is sucking in hot air until it is given an isolated or direct cold air source. You should try tests with an open hood, cold air source on both, then a test with the engine hot and the hood closed.
Cold air intakes do have the benefit of better torque in the low to mid rpms vs. a short ram.

i have my j's kit sectioned off from the engine wit a stainless steel plate an a cold feed pipe run thro it...it doesnt absorb any of my engines heat but still find the v2 better in high rpm...only way really 2 find out is a dyno run...but there is not many places round where i live that have a dyno an the ones that are a very expensive

woah, you got 2 ek9s???! lucky!

maybe one engine isn't as good as the other... power delivery will be a bit different and they both will have a slightly different power line on the dyno for sure.

D'janiero: i will for sure, maybe I can borrow the fan off a stupid electric supercharger, install it onto the cold air feed pipe and hook it up to a fog light switch or something... hmm...
 
no jus 1 real ek9 an an eg coupe wit a b18c thats my track car...the ek9 is my road car but i also have a b18c in that too...engine condition in both is similiar an mileage is similiar too

so how can u tell? they both weigh diff...
 
haha the coupe has been lightened to extremes...it weighs about the same as my ek9 its jus really a shell wit some carbon bits an engine gearbox an driver seat....in standard form they only weigh 50kilos more than an Sir

hi, can we hve some :pics: of that coupe..?
 
Once the pictures are on your computer, make a free photobucket account.
Go onto photobucket and hit "browse" and browse your folders and click on the picture you want. Hit "upload", then once its done uploading it will show a thumbnail, underneath the thumbnail click on the "img code" box. This will automatically copy the img code, so just go to the post you're making and click paste.
 
hmmm, thats strange, I don't know the original weight of the EJ coupe but what about your exhuast system? ej coupe does have a longer exhaust system which would produce more torque. Unless they both in the same car and setup, then you can't really compare it to the most detail.
 
way2fastforu: sorry man, I remember reading something about Intakes and got it a bit mixed up, yes CAI does give more top end comparing to a SRI because of the velocity charge and colder air, but for a high powered motor, you need more volume without sacrificing cold air which is the setup I'm trying to do here.

SRI gives more low and mid range but accompany it with cold air then it'll become a WIN WIN.

2 nights ago, on a very cold late night I was driving home and felt more power on the lower and mid revs than usual... there was a lot more throughout 1000rpm-5000rpm... i was quite surprised... stock intake with cold air mod couldn't compare!! :D
 
both cars have pretty much the same setup in them its jus the coupe is stripped out completely to try match the weight of the 9....ya good cold feed on an iduction kit on a cold nite makes them alot of fun to drive...i love wen the frost is jus startin to come over here i take my coupe for a drive some nites an the top end is AMAZIN in it...the j's an v2 in my opnion tho are the best 2 induction kits on the market without goin into forced induction(thats only for cheaters)haha even tho i want a turbo in my coupe :D
 
short ram with an enclosed box + cold air feed = icebox +mugen
this sort of intake maintains great throttle response, giving power across the rev range.
aem cai + injen looses throttle response, and has a pause inbetween the cam change, however does give good top end rev range power
 
Have any of you guys got any pics of a short ram, with a good cold air feed?
I'm still convinced that you'll get some form of heat soak, if the filter is not enclosed, as well as having a good cold air feed.
I'd really like to retain a good throttle response, but the CAI seems to make more sense really.

Also is there much didference between the aem v1 and v2?
 
i found that both the v1 and v2gace different delivery of power across the rev range. to be honest, how i see a cai, is that it takes the standard rev range power, and manipulates the power delivery.
the v1 gace more power/pull towards the end of the rev range, whilst, the v2 was more lower to mid. they're just pipes at the end of the day, plus the v1 is cheaper :)
 
actually, Mugen intake is just a much better version of the stock intake. I would call it a CAI more than SRI because of the tight enclosure and long pipe. Doesn't flow as much because of the restrictive enclosure over pod filter.
