ok as a few of you know i have been fighting to get a group buy for intakes. it has had many set backs. for one i designed my intakes for the SOHC which has a VERY different piping than the DOHC. Here is my spiel on the differences between the DOHC and SOHC intakes (save the intake mani and TB)
the photo's below. SOHC is on the left of both photos
as you can see there is an axial torsion in the SOHC pipe. compared to the "flat" design of the DOHC, now the "twist" in the sohc pipe is nullified by the angle of the resbox
again SOHC is on the left
this bend in the SOHC res box is "restrcitor". in an intake you want as few curves as possible. As you can see by my intake
i have choosen to remove my res box. i have not noticed a loss in torque, which is ever so apparent in the DOHC's. with a straighter smoother pipe i have noticed: a better sounding throttle noise. and and improvement in top end. i have not noticed a drop in my pick up or off the line. if anything i chirp the tires more without my res box. i am currently concidering introducing a DOHC resbox to my SOHC custom intake. i do not know what thew effect might be. i will however need to build another pipe because my current pipe is too long to house said box.
unfortunatly i do not have dyno results. my stock intake has been "chopped" during and experiment and thus makes a base dyno unattainable. i however will dyno my car to compare the difference between my current intake and my current intake + dohc res box.
The DOHC res box is important to the intake system. it help give the engine torque. torque is important. on the SOHC i will give my honest opinion and restate that i think it is near useless.
Where is all this going??
I am about to start another round of Intakes in 2 weeks or so. I have streamlined my method and have designes for 4 different intakes, DOHC stcok replacement, DOHC CAI, SOHC stock replacment, and SOHC CAI. I would like the thank J protege, and lourdarp for thier paicients(sp) in allowing me to blunder my way into perfecting their intakes.
they are 2.5" mendral bent alumized steel. (dont groan AL-steel does not heat soak like aluminum does and when powder coated is more heat resistant. (i'm an engineer i can prove this, hell yeah edumacation) and i can weld it. (no paying for a shop to do it)
The CAI is a 3" mendral bend that goes into the space infront of your wheel well. (see pic above) you will need to either find a thin filter, or re locate you coolant overflow bottle. the APC, APEXI and K&N "normal" cone filter has a space oriented issue.
You will need to get a 3" filter adatpor. these cost less than 5 bucks on e-bay. go buy one yourself, it is cheaper than me buying a bunch, having them shipped to me. then shipping to you.
this iw what it look like un powder coated, (note i to the pic just before i installed the nipple for the PCV
compared to a stock DOHC pipe
this is the stock replacement style intake,
as interest grows i will begin to post prices. a CAI shipped should run just under $100USD size of the group buy permitting. now as usual the more people intersted the cheaper i can make them. and a stock replacement mendral intake will be cheaper than a CAI.
I am just gauging interest. but you could have an engine bay that looks like this:
