Lanos Sport New Intake Setup.

BosnianLanos · Post by **BosnianLanos** » Tue Mar 07, 2006 4:22 am

Since I never want to run a CAI on any car I ever own again

, I was thinking of an intake setup for my new Lanos Sport that would yeild similar, if not better performance. Effectively, when you take out the resonator to install an SRI, there is a huge empty cavern where it used to be, and where the engine sucks air from now (covered by plastic, where compressor and crank pulley reside). If you've ever put a temperature gauge or even your hand in there after the car has been running for a while, you will feel that it is much cooler than the ambient engine temp. Well, I want to improve on this idea. I'll take some metallic sealant tape and seal up the gaps to that bottom portion of plastic where the resonator used to sit so that there is an effectively a large sealed area right below the intake hole in the body where the SRI will pull air from. Then, I'll pull out one of the plastic fog light hole covers and rather than leaving it messy by leaving it out, I'm going to buy a velocity stack for a motorcycle that will sit in a hole cut through the fog light cover. With that, cool rushing air will be forced through the velocity stack into the "sealed resonator area" and with nowhere else to go, it will be forced up through the body intake hole and into the SRI. It will use the efficiency of the short length of the SRI, but will pull in much cooler air than a CAI ever could on our cars. And best of all, the chance of hydrolocking AGAIN will be greatly reduced.

Heres a link to the velocity stack idea, it won't be that big, or pink...

Now, I need your guys' help in locating a velocity stack/intake trumpet thats suitable for the job. I've found good ones that fit motorcycles, but they run upwards of $80.00 for a simple piece of curved metal. At lenght, I could just cut a hole in the fog light cover and leave it be, or use the black rubber velocity stack from the ribbed pipe that went to the wheel well from the resonator, but I'd rather have the clean look of a proffessional velocity stack.

SNAP.!!

Been there, done it. I have not tried anything else than windtunnel on it, and that was brief.

There is a Pressure wave built up at the front of the car at speed, and the Air flow through my version, not much different to yours was a little odd. BUT IT WORKS!!

I am going to elaborate it a little when I get Home. My next idea is to tap more into the 4inch cool air above the Track surface.

The "box" sits nice and low, so I am now going to try a "Scoop" underneath the actual box itself, possibly via an Air-Dam.

Inconspicuous, but I think it may be worth the extra bit of work.

Sealing the "Box" could make it hold water under adverse conditions, and this might just Hyd-Lock the Engine, So, I put a drain into it. ..... Worth considering.

Good work, I like the look of the car, subtle..... Wolf in Sheeps clothing!!!, and doesnt attract the Cops, or TWOC'ers !!!

There is one other idea I havent got to try yet, and that is putting an Intercooler in line with the inlet(Yep, No Turbo), but the Air flowing through the core will cool the air.

So, no need for an expensive one either, BUT, what about the induction tracht length, am still trying to work through it at the moment. I do know the result will not be great at immediate off the mark, but will come into effect after a few seconds.

One thing for sure.... the rest of the Bumper at the bottom is going to have to be carved out to put it in... or at least a grill that looks the "Biz".

Anyway, I am interested in your findings, keep us posted will ya.

Ok So lets say you get the velocity stack and put it in. What kind of pipe are you going to run through to the intake. If you are going to?

I don't intend to run any pipe. I'm banking on the fact that the air will have nowhere else to go but up into the intake hole in the body. My other Lanos had a CAI that hydrolocked in a freak storm we had here last month. The reason I proposed this new setup is because it does away with the piping and the possibility of hydrolock.

without a turbo the intercooler would just restrict the airflow b/c without boost all those fins in the IC just get in the way. you would more than likely loose a lot of power.

adding to that the fact that the air inside the intercooler is as cold as - or as hot as - the air outside the intercooler so no temp. exchange occures whatsoever... you will just end up with more restriction and waist of money and time.

Sure, there will be a mild restriction, but shouldn't be too much.

The theory here is that if air is traversing the Core of the I/Cooler, it will have a cooling effect, and maybe drop the temp by 2 degs or so. Now we all know about wind chill effect, and if the cores are big enough, ie will pass air at the volume required by the Engine... Maybe there will be some positive effect to be had.

I do know one thing,.... these Stacks are carefully designed to operate Near the Inlet manifold, and work with Negative Airpressure at speed, and dont really have the capacity to help when it comes to "Forcing" air into the Manifold from a distance... the the open-to-air Surface area is very small.

To generate any kind of positive effect for air pressure, you really have to consider a large volume Scoop, and try to utilise the pressure wave built up at the front of the car when it is running along.

You will find that you have to overcome pressure buffer zones that actually stall air-flow, in and around any inlet that is exposed to the front of the car with respect to its forward movement, and the air that is "holding" the car back via Aerodynamics...( front pressure wave) or not! Look at how it all flows when it is examined in an Air-tunnel.

The I/cooler was an idea I have been thinking about, given I can get un-restricted air-flow though it. the pressure increase will neither raise the temp of the Air inside, so the I/Cooler will not behave as normal.... I appreciate that, but the effect I was looking for is to use wind-chill only. Theory has it there is some gain in there somewhere!?! Think about it, wind chill can freeze things, and lower temp by quite a sizeable amount, even in the Desert!!.... that is what I am trying to harness.

A noble endeavor. I've been trying to come up with the perfect method to cool the air in there without making some certain other sacrifices. I admitedly have not come up with the perfect solution yet. If I do, I'll let you know. You seem to be on a good track so far. My biggest fear is the dreaded 'hydro-lock'... *brrrrr* gives me the willies just thinking about it.

bypass valve

Nubira2.2 · Post by **Nubira2.2** » Wed Mar 08, 2006 1:14 pm

how does the bypass works?

Audacity Racing · Post by **Audacity Racing** » Wed Mar 08, 2006 1:18 pm

it's designed so that air travels through the center of it unless there is a hold put on it (water in the intake pipe). then the rubber inside flaps out of the way and the air comes in through the filter on the outside

nice

i need a good intake

BosnianLanos · Post by **BosnianLanos** » Wed Mar 08, 2006 11:08 pm

The only thing is that if you add a bypass valve to a CAI, it creates such a large intake area that you end up losing power from the CAI. Then you have what is a little better than an SRI.

I would go with a CAI setup like I had in my Green Lanos, but quite frankly, when compared to the 92-95 3 inch Civic SRI I had on earlier, it didn't have nearly as nice of a sound, and I don't think it made the same (and definitely not more) power. I remember my car pulling harder with the SRI.

The goal now. Revert to my "ye olde school" Civic 3 Inch piping SRI, get a nice K&N filter, hook it up to my oil catch can set up and have it all be sucking in the air forced through the velocity stack in the intake setup.

With the intake FINALLY done, that leaves room for some porting and polishing and a couple of ideas I've always had if I ever got my hands on a low-mileage Lanos.... Now I have one...

cheap bypass va;ves are open sponges... the really nice ones (like 100 bucks plus) have a rubber snap valve inside that flaps open when the air is blocked from the main pipe...

with bypass valves you get what you pay for
