Glad I've never listened to the retards on here.

Post some time slips.

>air intake temps drop 18C
Measured how? If you're such a fucking broke nigger you can't buy a k&n, why should we believe you you can measure your intake air temp?
Cold air intakes very rarely do anything but make you look like a clueless trend following faggot.

post dyno results

Just couldn't accept reality could you.
Nice literal shitbox inside of your car OP.

>>28549130
I have a $2,000 device that does datalogging amongst many other features.
>>28549166
it's a prototype, nigger

>>28549182
cool story bro, now post dyno results

>>28549182
You're a prototype.
It didn't work out.

That looks entirely safe and road worthy.

My air box sat right beside the header and is known to be a heat soaking bastard. The CAI I have now sits on the cold side, but not all CAIs are like that

>colder air temps
>colder intercooler temps
Cool, but you need actual before and after metrics. You can make huge improvements on air, fuel, and spark and realize it makes no meaningful difference on output because it turns out it doesn't really matter.

you have a $2000 datalogging device but couldn't afford an off the shelf CAI?

>>28549835
hks mushroom style filters are alomst the least filterest, they are one step away from just using a mesh screen filter rocks.

>>28549182

So did buying it bankrupt you or did you take a loan for it you can't afford?

>>28550177
>>28549835
good thing I have actual air filters that work.
>>28549879
It’s not about affording it. This retarded cooling setup won’t work with any off the shelf CAI. So I’d have to replace the radiator, intercooler, intakes, and who knows wtf else. So instead of doing all that, I thought first I’d see if I can do something myself to improve temps.

look at this bullshit. U-shaped piping. I probably should rip it all out.

>>28550286

lol
lmao

>>28550286
>nobody has solved heat mitigation on one of the cars with the most popular aftermarket and known heat issues
I think you're wrong, but maybe you just have very autistic requirements that aren't matched by any company

>>28550295
very strict budget limit, probably

>>28550297
>It’s not about affording it.
according to him he can afford it
https://pettitracing.com/products/tkt-cold-air-intake-rx7-racing
why he can't just go to one of the dozen different reputable rx7 specific tuning companies I do not know.

>>28550295
>>28550291
Autoexe makes a good one. So does Knight Sports. There’s a retro one on ebay for $200 that would work, etc. Like I said, the problem isn’t cost, it’s:
>is it worth replacing everything behind the front bumper to lower temps
vs
>is there a simpler way to achieve this?
DIY seems to be effective enough. The autoexe intake MIGHT fit, but then again it probably won’t.

>>28550306
I’ve already looked at that one and it won’t fit.

>>28550318
>it won’t fit.
a cold air intake made for an fd rx7 won't fit your fd rx7?
what other nigger rigged shit did you do to that poor car?

>>28550320
As you can see, that pettit setup has a stock intercooler and probably a stock radiator. My car has an aftermarket FMIC and an aftermarket radiator, both of which take up more space in that area.

>>28549130
>k&n

Edgar, go home. You’re drunk.

>>28549123 (OP)
Nice work anon. It could use a bit of work looks-wise, but building stuff at home that works is always satisfying and s o u l f u l

>>28550318
>This induction kit is compatible with nearly all intercoolers that mount in the stock location, and can be modified for use with virtually every imaginable setup.
>"it doesn't fit"
is your car like crash damaged and they didn't straighten the front sheet metal correctly or something? Is that how a chan poster could afford an FD in the year of our moot 2025?

>>28550314
>>is it worth replacing everything behind the front bumper to lower temps
It's an FD, the answer is yes. Lowering temps is the single most important modification to do for it. You make it run cool, you make it reliable (relatively speaking), first. Then do your hotboi mods for the Instagram

>>28549182
I just have an old laptop with free datalogging and tuning software (picrel, the romraider and ecuflash combo).
>air intake temps drop 18C
I don't believe your story at all, however. There's no way your temps dropped 65F in the same use case / duty cycle. And especially not temps after the turbos. I could see you getting this difference measuring the orig after heat soak and the new one right after a cold start, but this is bullshit and you know it. I could maybe see temps before the turbos dropping 1-3C.

So i was the pedantic idiot in the other thread, didnt realize this was RX7 anon and his bullshit.

>>28550985
IF he has been able to move the point of intake mouth out of the engine bay, such as ahead of the radiator or in the foglights, I can see a 10-12C peak drop being realistic. If all he's done is shroud the filters and extend the "box" away from the engine then yeah it's still mixing radiator exhaust with whatever else it picks up.

Does an FD even have enough of a hood>bumper gap to make a modern style intake opening? Because OP that's what I'd do if routing to the fog lights is a problem or an aesthetic no go.

>CAIs don't do anything!
What is this fuckwittery?
I think it's CARB, trying to sell gas price increases every 6 months because "Muh weather changes!"
Nobody should work for the EPA/CARB unless they can pass a test on the Carnot cycle.

>>28551064
Get a different bumper and put a NACA duct in it

>>28551127
>Nobody should work for the EPA/CARB
Fixed it

>>28551127
Cais rarely do anything unless your car is poorly designed. Most people do it to look cool

>>28551265
Me? I do it to make 4-cylinders sound deep when I'm on 30+% throttle while keeping the cruising noise mostly the same. I don't like messing w/ exhaust unless it will actually net me power.
Those turbos and pistons going down are gonna suck air through just about anything.
Moving your filter location isn't going to make the turbos cooler once it's at operating temp and moving.

>>28550272

That's what My Summer Car should've been about. MacGyver shit that goes wrong almost immediately or at the worst time possible.
