Thanks very much in speaking in English, much appreciated Ive enjoyed you're videos before even though I couldn't understand a word
You‘re welcome.
It‘s also much better for me to be honest.
Writing subtitles was so time consuming, that i nearly lost all joy in making videos. 😅
G-day from Australia 🖐Thanks for another informative video, great use of English too 😀 Cheers..
Thank you. 😉
Will try to keep it that way. 😁
Thanks for the bi lingual video man :) makes it a lot nicer to follow along. Im going to look into this product, thanks for the heads up. I previously bought the DNA camber tops after seeing your video and really love them :)
You‘re welcome. It‘s also fun to do bilangual videos to be honest. 😁
Hello Phil! Great video again. Guten tag from Australia!
Thank you.
And a guten Tag to you too. 😉
Oh very interesting - this is going on the to buy list at somepoint
Great interesting video as always 👍
Thank you Mate. 😊
Hey, wieder mal ein super Video, danke dafür.
Gruß
Gerne. Freut mich wenns gefällt. 😊
WOW!! Your English is amazing!! Thank you.
Thanks Mate. 😊
thank you for the english explanation :)
You're welcome. =)
Hello Phul. I listened (looked) and almost all your video's. Although I followed most this was really fun to hear it in English. I thank you.
I think I must invite you to Africa to come and help me to install one...smile...
Never been to Africa. 😁
Where would i need to come? 😉
@@RotheliRacing Johannesburg South Africa. You might have heard of it before.
@@lukasvr5088 hahaha. Yes of course. 😁
Now I'm curious about downpipe + DTUK.
Hey Phil! Good video. Your english is really good. Can we still use the DTUK Race box together with the HJS downpipe + a full catback (opf deleted) exhaust? Which map are you using?
Yes Sir. You can.
I‘m using Map 1 +3 and it pulls like a train. 😅
@@RotheliRacing Why was the HJS + DTUK combination not measured?
Phil, inspirational video, as always.
In fact, this result is not very flattering for DTUK. The dynamic simulation, based on the published engine brake output, shows a significantly larger differences.
For idea. The idealized power and torque graph declared by the factory gives a time of 6.33s.
DTE measurement - stock car (281k, 354Nm) = 6.30s, + box (309k, 399Nm) = 5.66s.
Measurement PG Performance (Poland DTE dealer) - stock (275k, 388Nm) = 6.10s, + box (299k, 422Nm) = 5.59s.
The torque course in the entire speed range has great importance. Other measured graphs for stock cars show results between 6.35s and 6.55s.
I'm also going to compare stock with DTUK. DTUK had a very positive effect on me from the beginning (although I don't like boxes). Reaction to the accelerator pedal, appetite for speed. If it's just a placebo effect, it works very well.
I want measured times for 40-70, 70-100, 100-130 (3rd gear) - this highlights the differences in power curves. Josef CZ
@@nicolascageczechia1342 because i can‘t drive the DTUK legal on the street and therefore did it only once to measure and never did it again.
It’s a race track mod only for me.
50-130km/h is perfect for the HJS, because the turbo spool up is much better so that‘s where it gains it‘s advantage over the box.
I‘m pretty sure the picture will look totally different if you‘d measure 100-200km/h.
@@RotheliRacing The times I present do not involve any reactions, just overtake.
Do you plan to use Map2? HJS for back pressure reduction and some intake (maybe EVenturi, SCARA73, something else)? Intercooler?
@@nicolascageczechia1342 Map 2 only works with specific parts and OPF delete, so no.
I‘ll get a couple of intakes to test and we‘re building a IC with a Garrett Core.
Just follow our page or on CZcams and you‘ll see. 😉
Super Video wie immer.
Und ja also wer will es denn da inne besser wüsse als Strassenverkehrsamt?
Danke für das mehr fachi abkläre.
Wäre no geil wenn Du de Eventuri Intake teste würdisch, bi Regen. 😁😁😁
Sehr gutes Video.
Kannst du mir sagen, wo ich den Dichtring für die Downpipe bekomme? Finde ihn im Internet nicht.
Vielen Dank. 😊
Hab meine direkt beim Toyotahändler gekauft.
hey phil, did you notice any sound difference with the dp ?
Maybe a bit. But not really much with the OEM exhaust.
A bit deeper, but if you don‘t know it, it‘s nothing you‘d notice.
Du hat sich eigentlich Geräuschtechnisch was verändert mit dem HJS Kat? (Da ja anderer Fluss)
Nicht wirklich. Vielleicht minimal.
Auf einem Video unhörbar, weswegen ich auch keine Aufnahmen gemacht habe.
@@RotheliRacing donk da :) meiner is ja jetz schon so laut xD
Do you have a time with the downpipe and the DTUK box?
No not yet. Haven‘t had the chance to measure that.
Hello i wish to know if the engine light is on after the assembly? And your opinion i have a sport exhaust but is omologate, after the hjs the sound increase? Tnks
Hi
No engine lights and maybe a little bit louder.
It‘s really not much…
@@RotheliRacing tnks do you think that the sound not increase so much also if my system exhaust have not the opf?
@@giannin2436 have no idea to be honest.
I heard it with my OEM exhaust and a resonated Milltek and it wasn‘t that much louder with both.
@@RotheliRacing tnks so much
@@RotheliRacing i ask onother question do you feel the increase of power?
1:20 no! You need certain gas velocity to make the Best use of gas inertia and you need certain length to the point(s) where pressure change will occur- this will generate a negative pressure wave- it's called wave effect.
SoooI do I have to drop the front sub frame for the install or no?
Nope.
Did you need to remove the drive shaft to remove the downpipe?
No you don‘t.
Muss die ECU angepasst werden? Oder einbauen und gut ist?
Einbauen und gut ist.
Mit Map performt das natürlich noch besser.
Hey guys ! Can someone translate what he said in swissgerman please i live in Switzerland but speak french
Lol nach 20 Jahren erinnere ich mich an euren Dialekt, das nächste mal sprecht auf Hochdeutsch. Grüße aus NRW
Ich denke ich bleibe bei English und Schweizerdeutsch. 😉
Eine dritte Sprache möchte ich nicht zusätzlich einführe
@@RotheliRacing Perfekt keine problem ich wünsche euch eine schönes wochenende
Any chance you can summarise the CH street-legal stuff for us from ticino :)
What exactly do you mean by that? 😁
@@RotheliRacing I meant if you could summarise / explain in english the part where you speak about whether the downpipe is street legal in Switzerland (i don’t speak swiss german unfortunately)
@@leopoldocarbone yes. It is street legal. 😉
Gutes erklär Video hätte gerne noch ne leistungs Messung gesehen mit und ohne kat.
Aber das mindeste wäre mal nen soundcheck gewesen das fehlt leider....
Da ich das als Hobby mache und Prüfstände nicht so richtig gratis sind, ist das leider nicht möglich.
Und ein Soundcheck ist nutzlos, weil du schon in echt praktisch keinen Unterschied hörst. ;)
@@RotheliRacing, achso okay dachte ihr hättet da irgendwo jemanden mit nem Prüfstand.
Gut zu wissen das der kaum Sound holt.
Ich warte immernoch auf meinen GR hab den vor 9 Monaten bestellt, sollte so langsam hier sein und abgeholt werden können 🤷🏽♂️.
Dann wird ersma umgebaut, der wird keine 50km Oem bleiben 😂.
Deine Videos sind echt meeega gut, auch wenn ich mich anfangs ersma an den Dialekt gewöhnen musste.....
@@stephenpru6482 haben wir auch. Aber der kostet trotzdem sehr viel Geld. 😅
Und danke. 😊
Any difference in weight?
Maybe a few grams.
Top top... weight difference??
About 400g lighter, because the heat shields can be removed.
