Default Why is the injen intake like this?



How come it gets the air from around the wheel well?

because (correct me if im wrong) the air in teh wheel well is 10 degrees cooler which will give you a 1% hp gain either way its colder air pushing in

Default hmmm

i have the injen intake. i drove my car around for 30 minutes and came back. i opened the hood and it was steaming in there. i took off the little cover next to the hole where the intake enters the fender. i stuck my hand in there, and it is noticable cooler than it is in the engine bay. it is actually a lot cooler. they dun ahve official dyno charts for the intake, but i had the rallispec intake before i installed this one, and the injen actually performs a better. i think it is becuz i didnt have a heat shield for the rallispec. my bro has a 97' nissan 240sx. The injen intake for his car does almost the same thing, and the dyno charts reviel that it adds 14.9 hp to the wheels to the car. not bad not bad.

14.9 to the wheels!??.....correct me if im wrong but 14.9 to the crank is a little excessive for just a intake alone.

Default yea

im not lying, and im sure injen isnt lying. go to www.injen.com .look around, and ull probably come buy nissan 240 sx somewhere. check the dyno chart. also, i have an issue of sports compact car, and it also displays 14.9 whp gain for the 240sx. oh yea, apex n1 cat-back gives the 240sx 15hp to the wheels also. 30whp from intake/exhuast sounds incredible and unbelievable. better believe it.

I don't think it works out that way. You can show that one mod can add X amount of HP compared to stock and another mod adds Y amount of HP compared to stock. But you can't add X and Y together for total HP gained with those two modifications.

I highly suggest wrapping that long aluminum tube with something to prevent heat soak. Aluminum is a very good heat conductor and all that exposed piping in the engine bay is going to be effected by the heat the engine is producing. Every little bit helps!

And as far as the 240 goes...who knows, maybe the stock intake was really restrictive. Either way...it doesn't matter 'cause a 240 is not a Subaru.

Default uh huh

exactly, 240 is not a subaru. but ne way, i have the injen for my car, and it is really good, better than the rallispec that i had before. mainly cuz i didnt have a heat shield for the rallispec. just go to www.injen.com . they have dyno charts for most of the cars they provide intakes for. average gain is 10 whp. oh yea, about the 30 whp intake/exhuast comment i put down, maybe im wrong, but that is the way i look at it. im simple minded. ahahaha.

To see why you can't add up mod hp, check out cobb's site. They have dynos for their Stage 1 and Stage 2 NA packages.

Baseline = 122 whp
Stage 1 = intake + cat-back = 135 whp (+ 13whp)
Stage 2 = intake + cat-back + headers + pulleys + cat = 145 whp (+ 23 whp)

So, no, you will not make 30whp for just intake + cat-back. Now, of course, 13whp is probably close to 18 hp at the crank, so you could probably realisitically claim around 183hp car While the stage 2 runs somwehre in the 190's at the crank.
