What hood is that and what kind of front lip?

What hood is that and what kind of front lip?

It is at alibaba. It looks like a mugen CF hood.

I dont know about the lip.

I can forward you their contact if you are interested.

Your lip is also from Alibaba? It looks nice. Just trying to figure out what to put on mine to match the Voltex wing that will be arriving in another 12 months. ?

interested in link to hood.

any concerns with rain?

interested in link to hood.

the car only comes out on track days and maybe weekends. i have 2 other cars for daily and rainy seasons.

that's not my car but the sellers pictures. i didnt buy a lip but thats the same CF hood i ordered.
I probably will not buy a lip since i know, i will break it!
My apex wheels are coming next month. Apex wheels takes month to get when its back ordered

Fantastic information in here everyone. Thanks for sharing! Regarding oil temp, I think we all know quality oils can handle 300F, but its the crank / connecting rod bearing metals that start to get questionable at 250F and higher, per Mike Kojima at Moto IQ.

In preparation for a track day at my home track, Road America, in one week, I added an oil cooler. I installed a Setrab Series 1 oil cooler with 25 rows. Mounted on the left side, it has a 36% larger surface area compared to the Setrab 16-row Series 6 cooler included in the HEL kit, and will have a much smaller pressure drop (shorter rows + more rows = less pressure drop).

To accommodate the larger cooler, I removed the left brake duct tube. Airflow now enters through the front bumper brake duct opening, passes over the oil cooler, and exits through the existing fender liner hole where the brake duct previously connected. This ensures continued air supply to the brake air guide for brake cooling. Sorta robbing Peter to pay Paul, but I think in this case, Peter still gets his share too.

I'm using the HEL sandwich plate and custom lines I made. There are no leaks that I've tested extensively on the street. I have a Glowshift dual oil temp / pressure gauge that I'm installing tomorrow. And then its data gathering time. Going to see how this setup does with stock everything else. I'm definitely optimistic.

A bit of fun data... I repurposed the HEL supplied Setrab oil cooler to my 2023 BRZ. That thing is stock running 93 octane. I also mounted it off to the side. I have a local togue road near me that is 9 miles of winding and straightaway bliss. When I hit this road with my BRZ in OEM form, I see oil temps in the mid 270s F, same as the oil temps I see at Road America. With the HEL oil cooler, my max oil temps are 245 F. So definitely about a 30F reduction. That said, undersized for the FL5 application... and with it blocking airflow to the FL5 radiator, doesn't help with water temps.

Interesting response. The engine oil temp value was clearly copied and pasted from an erroneous source. The car will be in limp mode, oil will have broken down, and the heads warped well before 1,292 °F.

At that point it will all be a puddle of molten metal?

This looks great. Thats the plan tomorrow.
I will definitely test at the track. Worst comes to worst, i have to custom 2 oil coolers (left and right side).
I have a snorkel blocking the radiator so im sure its affecting the cars temp.

Ya someone is BSing me.
So far, per gridzilla and pointbypatrol. Their cars went to 302F.
I observed from pointby that his car went to 302F for a while then became --- zero value until it went limp mode.

That was on the white car for sure. That intercooler really wasn't ideal for my application!

I just rewatched my track redemption video in the black car and saw it hit 284 at 88-90 ambient.

I installed a spoon thermostat in the 4piston engine, and I've noticed cooler temps driving around town. I've got a track day coming up on July 13th which should be insanely hot outside, so I'm kind of curious to see how it goes.

Was able to fit the @drivencrazy.sg fk8 hypothermia kit onto the fl5 oem crash bar successfully! Will be testing on the street until I'm able to take it to the track this fall.

Did require me to make a custom bracket which you can see the mock up with cardboard and painters tape. Basically the bracket is just a rectangular piece of steel sheet metal I got from the hardware store. It's bolted to the inside of the bottom of the crash bar, with holes made to just barely fit the posts/bushings of the radiator. The bottom bracket is rock solid.

Some of the core is hidden behind the crash bar, but the top portion of the core is exposed and will still take up the entire grill area. Even if the bottom was fully exposed it wouldn't get air due to the limitations of the size of the grill opening.

I also had to cut the middle of the bulkhead to create enough vertical clearance for the radiator, otherwise the posts/bushings were directly touching the PRL intercooler. Plus this allowed me to have a little more of the radiator available to catch air flow.

I used the support brackets from the kit to stabilize the top of the radiator by bolting them to some rigid tabs of the OEM radiator support that hang down.

The hoses from the kit route through a small gap in the OEM radiator support. They barely fit but they are not kinked or squeezed (I will monitor if the lines start to show any wear in the upcoming months). The lines tap in as designed into the bottom of the radiator and into the thermostat. The thermostat hose did have to get about 1.5" cut on the side that plugs into the hypothermia core as it was just a little long.

I do have some ideas to share with driven crazy to make install much easier and to where it would not require any modification/cutting. We will see if we are able to successfully implement these changes to make a kit that is more consumer friendly. For now though I myself will run this set up and monitor it for reliability (hoses mostly) and performance (I can't see why it shouldn't be equal to the fk8 set up).

i thought the spoon thermostat's throw CEL code?
please let me know the outcome. i might run around july which will be 110F

I've got Hondata

Got it.
Does that mean cel wont show up or you clear the cel thru hondata?
I also have hondata with phearable tune.
