RR-Racing Intake Heat Shield Install In Lexus RCF Track Edition & Secret Open Intake Mod

[@2ZZGE100]

Julius and you make a great team! When I had the vacuum line disconnected, there was a noticeable loss in low end torque below 3600 rpm. I reconnected it and never disconnected it again. That is why I got the AFE Power cold air intake as it retains the OEM airbox while giving a new pipe and filter.

[@thehuangbros]

That is good info

[@Parakoopawing]

Thanks for the info! Did you just disconnect the hose or did you also block the solenoid?

I’m really hyped to see more on the track edition as I have the same car and would like to see the different ideas that are out there. I know there’s not much for our car as of now I’ve already done exhaust intake mod lowered more carbon fiber parts. But I know there’s no tune available for our cars. I was curious to know when he left the flap open on the intake Did that increase power low end or did it decrease power low and what were the games for doing that?

[@thehuangbros]

Im thinking of a way to test the flap theory

[@blakeyy9424]

@@thehuangbros that would be great, ive been running the open intake mod for about a year now and wondering if its been worth it lol.

[@thehuangbros]

@@blakeyy9424 ill look into it but some ideas would be great too haha

[@ap50]

Hey man, would u recommend this recommend having it for some time now? Is it worth it or just a gimmick?

[@elonmusk8667]

Its just a gimmick ... I want to see dyno numbers.

[@Meaper2U]

Did the Heat Shield provide any power difference? Anything noticeable right off the bat? Living in Norcal, we have hot summer and decently cold winters. Want to see if this is something that helps.

[@thehuangbros]

I can tell you right now that subjectively, he felt an increase and he went to do two laps at the Nurburgring right after we filmed this video. With the flap open also

[@WorksProductionFilms]

Hold up this whole time you was suppose to cut the plastic for the heatshield so cold air can come from the wheel well!? I had my heatshield on and didnt cut the plastic cause well no instructions lol.

[@thehuangbros]

I left mine uncut

[@WorksProductionFilms]

@@thehuangbros yeah same i dont think it would make that much of a difference from cutting it

[@thehuangbros]

@@WorksProductionFilms i remember there was a stupid argument about it online. To me, the main goal is to shield the intake from the heat coming from the engine and header.

[@milanharrisracing]

any way to get some details on the seatbelt setup on this car! im new to the RCF and will be tracking so would like to setup a solid belt system. I also drive it during the week some thanks! have enjoyed all your vids!

[@thehuangbros]

Sparco 4 point harness. Need to buy the rings that allows the sparco seatbelts to hook into.

[@andrewtrieu4026]

I used a valve stem cap and twisted it on the end of the vacuum hose!

[@thehuangbros]

Easy procedure.

[@racegt3394]

Haha this went from G(General Audience) Rating to R Rated 🔞real quick. On a serious note though, I contemplated this mod but I monitored my IA temps in original stock design and there was zero increase in temperature when the intake opened under wide open throttle. It was surprising RR made the claim on substantial temperature increase. Reason why I always do my own independent tests. If I do a mod it's absolutely going on the dyno. With the IA temps it was easy to check with OBD Fusion app to test validity of whether the stock air box necessitated this mod.

[@markmoosai]

I was also on fence with this mod. Did you monitor IAT when the car is moving? I will do the same and report, that is if my OBD tool can do this. It read live data but it is older.

[@racegt3394]

@@markmoosai Yes the OBD fusion app will give you live data while driving. I did this for several weeks in various driving conditions

[@thehuangbros]

He took it to nurburgring after for two laps and stated he felt it being a little easier to climb the upward slopes on track

[@ljc1821]

​@Mark what did you eventually end up doing regarding leaving this mod alone or adding it?

RR data logged and said the Temps dropped by 5 degrees. Are are you saying they just lie to get people to buy their products??

[@Skittlezz45]

What's the value add for leaving the intake box open 24/7??? I gotta think that Lexus spending millions on R&D did that for a reason.....

[@thehuangbros]

🤷🏻‍♂️

[@racegt3394]

Spot on! Why pit yourself against the $$$$ of R&D? You actually loose low end torque when you leave it open all the time. If one wants to go against the grain do your own independent testing. It is not fortuitous to blindly go into willy-nilly "performance" mods

[@Parakoopawing]

The flap is not made for performance but rather for noise emission control. Unplug it and enjoy the engine sound below 4000rpm. It’s a difference like day and night, feels like a completely different car. In the end just a mod for the emotions.

[@gervilleharlequin994]

Great video. I want to add the heat shield to my F. Was concerned about connecting the hoses.

[@thehuangbros]

It isnt too hard. But you may experience a bit of struggle

[@marcodorff5811]

He needs an oil catch tank 100%

[@thehuangbros]

I agree but in Germany it would be consider a engine mod and that is a no go. Only reason why the heat shield was ok is because it was a add on for decorative purpose

[@Parakoopawing]

That's a great idea, thanks! As Barry said, an open system is not legal in germany. But i could have a try with the closed system - i will look into it!

[@RK1FX]

The sad thing about jdm cars is that they won't ever get a quality product as the German rivals do. Look up m3 e9x/rs5 v8/c63 m156 intakes. Those look amazing and are actually brining solid gains.

[@thehuangbros]

More customers from those groups.
