You have measured? Then wassup. Why u insist against measured facts and wanna loop around?

Stock Nissan was/is CAI. Will end being park bench...

Btw. I keep wondering: why you lock some threads up, but will not do anything on some CO hotheads (crack addict him/herself?) flaming persons of drug abuse - thing which really is not this forum is about?

I dont know kc...i think that scoop would look funny with the lines fo the car.

The only scoop I think would look good on our cars are the ones the Toyota 4 runners/land cruisers or whatever they are calling their SUV have. Small rounded scoop. Unfortunately those scoops are part of the hood and you would have to buy a whole hood, cut it and weld it on to our hood.

just my .02.

I think that's why I think I'm going to make it myself. Of course, the fun part is going to be the vaccuum controled butterfly . Give it that old school muscle car look.

I looked through a lot of the universal scoops out there, but didn't find anything I liked.

Wiking

Btw. Whaddaya gonna scoop? Looks, mosquiToes, ...?

Anyways I already think yours will look great. (hmm. its drag will add 0.01s)

kcidmil

Now the real question is... how much more HP and torque will it add? Shorter air path, with direct connection to outside air. I'm not thinking it will add much.

As for why... I haven't seen it done yet. One problem I know I'm going to have is alignment of the scoop to the box... as well as sealing. But sealing isn't too hard. I just wish I could add a turbo setup along with it. But the wife would

Wiking

Shorter air path will give beneFits. Especially if you find out the right form. I think the form is way beyond the theories and calculations. But first I would test extra long, a 4" pipe as long as the vehicle... But who can figure it out...And of course, yours will be real cAI

If I had the bits, I would block the heat inferno directed to lower intake. Plug it off, and route the water out from engine ends. I bet Huge difference on lower rpm because of nonheated air.

Wives have a logic men never follow: maybe she simply wants a non-push car? Buy her honda; at least forum seems to like em, after that, she will let u turbo...

.......search and find the info??

I think the best way would be to add a cone filter to the MAF and leave the old tubing that ran from the stock airbox to the left headlight wich will blow cooler air directly onto the cone filter while the car is running about 30mph or whatever speed.
i've seen a site that explained this but forgot where.
my 2 cents.

kcidmil

Well I just have to see what turns up. I'm going to go down and dyno the car before and after I put on the intake I got from Mr. Gone. Then I'll do the same thing again when I build the air box and scoop.


She has already made that known. She has already said she hates the clutch.

She would shoot me if I suggested we get a Honda... I think I'd shoot myself for suggesting it. Honda's are not very liked in my family. She already said she wants a old muscle car... she's not sure which one yet... go fig.

I was thinking of a Nomad... I'd love to work on one of those. But it's the car she wants... and as the old saying goes... "If momma isn't happy, then NO ONE is happy!"

Dyno horses are lame. Buy the 150$ 'onboard dyno', and then the results are what you get on the street.



lol. No need to search smtg what I found out.

kcidmil

But there's too many variables... like what street I'm on... temp of the day, wind speed and direction. If I dyno it in the shop, I have close to the same conditions everytime.

Wiking

That is true. Tests have to be done on similar conditions, maybe same day. But the other end of this issues is that dyno simplifies too much: no air movement AND...plus chassis geometry plus whatever?

On THIS intake air temp issue this is crucial: results are biased (for air intake location).

Remember that the engine generates up 70kW heat energy. If car is stationary, that heat is mainly 'trapped' under hood. (Its NOT little, 15 houses get by through winter.) Of course CAI gets good results on dyno. If car is on the street, moving, CAI is maybe -10% worse through whole performance area. Now what do you need? 'Vinyl horse performance poof -slip...'

I am NOT saying that dyno is no good. I am saying that check out its limits, test all, keep that what is good: "Prove all things; hold fast that which is good." ...like the bible, says, the only real scientific method to test things... Then compare with the onboard tester...

Btw. I am asking advice: what is best such onboard accel/pwr test device and price? Where to buy?

kcidmil

Well I'm using the dyno to check numbers... I'll let my back tell me how much of a difference there is on the road. I'm plastered to it as it is when I punch it.

Also I was trying to get the car timed at Pierre during the SD Maxima Meet. But it looks like the track isn't going to be open. So I guess I'll have to bite the bullet and take it to the 1/8 mile track at Sturgis. It might give me a good idea between before and after. But as usual, I'd have to do close to the same conditions... very hard to do.

As for the best on board device... Like I said, there's too many variables that come up. And this has been noted by some in the Audio/Electronics section. Might want to ask the question there. I deal manly in Stereo equipment... I have no idea about any of the other gadgets out there.

Wiking

Yea, dyno is at its best in change-comparison as input air temp stays constant. Let us hear, interesting! I bet u are buzzy... one cannot sleep when such project is ON. Btw. Thanks for the tip.

kcidmil

No problem.

The actual project hoodscoop project will not start until after the SD Maxima Meet. I'm currently stuck on the other side of the world from my car right now. But I'm busy none the less. I'm sketching out how I want it to look. I might go with something a little shallower. Give it a low clean cut look.

Dark Maxima 57

where can you get the best cold air intake for 93 dohc for cheap but polished?

smtg???????????? oh something. Then why did you ask?

I got mine off of ebay when they first started showing up. I just checked my paypal and I paid $62 shipped for it. I thought I had paid around $40 shipped but I couldnt remember so I just checked and I was wrong.

I got it from a seller named liveonspeed. I am not sure if he still carries them or not though.
