Our weather is hit or miss in the winter of late. We used to get snow storms 2-3 times each season and now we are lucky to see one snow day. Yesterday was 68 F degrees lol... Normally after the holidays it will stay in the 30's to 40's for the next three months.
Damn that’s some pretty wild swings , looking out my window now I see we’re blessed with the first years’ snow. Knowing Salem all normal life will cease to exist , Roads will be like a scene from I am legend , everyone fleeing for boats and choppers.

With the roads cleared up I went to grab the remaining oem parts needed for the 4P oil pump install. All the websites say it’s fine to “reuse” the oil chain tensioner (and it may be ) but I chose to put a new one in the batch. Picked up a little billet tensioner cover to polish up as well 👍

I decided to put the plug cover and black dipstick on the unfinished silver cover just ‘cause. I am thinking of polishing the upper coolant housing as well 🤷‍♂️

The new suspension showed up today , truhart drag spec coil overs. 12k front/18k rear springs and extended rear shocks. I have truhart upper camber arms on the car now and was very pleased with the quality and finish , the same can be said for the new arrival.

I also started taking some measurements for a ram air setup / what was needed to clear into the bumper

I like the idea for the intake. I think you would have better results from a velocity stack at that fog light pick up that feed a airbox with a SRI with velocity stack inside of the airbox. The extra length of the intake pipe equals more friction.

Ya I just put my hybrid one back on there and wanted to see what I could come up with using my mixture of couplers and piping. I’m hoping to be able to test a few different intake setups on the dyno when I go , if the bumper is off it’s just a minute or two for changing between them. 👍
You can really hear the air moving 😎 I love how deep the engine sounds 👍 this was pretty cold still so I didn’t want to give it too much.

Have you considered sizing your velocity stack for a given speed range? I think that one you have there is probably a very low speed size for your power level

Do you mean have one designed with more of a bell mouth ? I like the proper fabrications ones but I guess I would have to see a real world difference at the track through some testing. The one pictured is the hybrid racing -designed to have a filter go around it so that’s probably another shortcoming. Do you have any suggestions how to go about a better one ?

I have a friend who is my go to fab guy so ideally I will have several different intakes to test out from 3”-4” ID. To go with the larger ones I’m thinking about a 74mm tb and then port match /taper the adapter plate 74-70.

Ram air doesn't really become significant until you're up around 100mph or more. At that speed your intake velocity is much too slow to be super beneficial. The closer the ram air speed is to your intake velocity, the more effective it will be.

I roughly calculate 65mm effective intake diameter to be about right for my k20a at 160kmph. I think the k24 will be similar power so i would start around 2.5 inch and try going bigger and smaller than that.

The problem is you can't really measure the benefit in a dyno unless you can get a nice linear high speed air flow directly onto the bell mouth.

That is some interesting info. I guess I was thinking if the bell mouth was getting air “rammed” into it that was good nuff but it doesn’t sound like it 😆. I like rearranging and test fitting stuff just cause alot of the time but I would like to end up with the intake that gets me down the 1/4 the fastest.

that was kind of what I was thinking leaving the bumper off for the dyno trip. By using a "two stage type intake", section - airbox - air supply section should make it easier to control air to the filter. From studies I have read, intake systems that are able to direct air around the filter in a circling motion do the best. The intake I am linking does just this, the air supply tube reduces to increase air velocity & pressurizes it some, and due to the filter housing's design the incoming air circles around the filter instead of hitting a bulkhead.

For tighter spots this EP3/DC5 style seems to work when the airbox is in the OEM location.

Those are some nice looking canisters! I do like the idea of a wheel well cold air feeding a v stack inside a housing in the engine bay to help keep the pressure etc. my intakes will be trial and error, part of the fun is putting them all on 😂

A couple small things arrived to further my project , a nice 10” SPAL fan and a new oem chain tensioner 👍

it doesn’t fit the shroud 100% but I will fill in that small gap somehow 👍

and just a shot of the new drag coils, very happy with these. For how stiff the springs are it drives nice on the street, on hard corners the car No longer “leans” enough to meet the tire and fender 👍 it’s much more confident in the twists as well which sounds funny but the old tein was way past it’s days.

All of the BTCC teams run them. The new CTR has an after market kit that feeds the air filter the same way from the hood/ upper radiator support housing area.

To fill the gap you could make a ring that is large enough to catch the mount screw of the fan shroud and overhang enough the aluminum circle to flush the inside of the fan's shroud. On the opposite side using a strong adhesive between the new ring made from carbon fiber, aluminum, or plastic. Finally mount small thin 90 degree angle bracket's along at the even numbers on the clock

I should have bought an 11” fan but I will do something to make this one work, it was a steal at $60 for 1100cfm advertised.

$60 is great fine for FAL. a ring would work, they sell sheets of carbon fiber that are not too expensive. and a ring could be cut from that easily using a hacksaw blade without the saw.

That is a great idea , I will look into that as well as a few other things. I’m working on getting my detailing business off the ground in my spare time (hopefully it will become full time by summer) so I won’t be taking the engine out of the car anytime soon as I need to be able to move it freely in and out of the garage for any customer ceramic coatings /polishing. But I can definitely sort out a radiator fan 😂

Yesterdays weather was too nice to leave the coupe inside. I put the bumper back on after work, checked the oil and took my wife out for a quick drive 🙃

Polished up a friends car today , will be back tomorrow to do others for him as well 😎. Stock k24a turbo mr2 making 600+whp. The body/paint has a lot of imperfections but for a couple hour job it turned out very nice 👍
