Now this is interesting and I am really excited to hear about the results. Please do a before and after dyno. Are you also increasing the diameter of your intake duct? How much of a power increase are you expecting? Is this a bolt on, or does it require an ECU reflash, etc?

It is not a bored out version, this looks like is a 82mm Porsche throttle body, which can be bought relatively cheap (see prices ni the 160 euros from Bosch).
Another good find Duece2000!
Is the TPS of that unit similar to our cars? Or are you going t adjust the signals electronically?
Or possibly easiest if the signals are not the same, are you going to fit the original TPS somehow to the TB?
Edit: Considering they are selling the Dutch KMS engine control units, I take it you are going to use that also to control the TB, s adjust the signals electronicaly?

dear sweetheart, this is not a discovery of deuce2000 but simply a picture that sent me the builder of the aforementioned company.
I simply ordered a 83mm TB for my car and I do not know anything else about electronics and whether it comes from porsche or something else.
you could ask the questions to him because he's technical!
I am simply a buyer of a product that I will install when ready.

Nigel just wrote me and bought a TB from a car Wrecker to carry out the comparative tests. if he need it he will contact you

[QUOTE = Conte Iblis; 1.973.243] A quanto pare non è più Maxbore sta facendo Jaguar rebores T-corpo: - ([/ quote]
sure that makes them! I also had it done to maxbore before discovering www.pinkbatmotorsports.com
but the modification by MaxBore brings the butterfly valve from 76 to 78.5mm. ( see the photos about it )
this new butterfly will be 83mm!!!!

I didn't know Maxbore stopped doing it, that's a shame.
The 4.0 TBs where easy to bore out to 83mm, but the later (smaller) 4.2 TBs where a bit of a hit and miss, some where only able to go safely to 78 and some to 82.5.
Chances are 99% I would say the Bosch TB works the same with the TPS output as the Hemi 85/90 mm TBs I have used, so the converter I have will be able to work.
Problem is that the signal converter I use to adept it for our Jaguars is expensive (450 euro ish), but as the Bosch unit is relatively cheap, it could be an option for some more demanding setups especially if it is a direct fit bolt wise. The Hemi's I use (from 80 to 90mm) have a wider bolt pattern, so would require much more work and is cost wise only interesting for very high airflow demanding setups.
It would be great for the community if pinkbatmotorspsorts could make a more cost effective converter, otherwise I am willing to offer mine.

[QUOTE = avos; 1973454] Non sapevo che Maxbore avesse smesso di farlo, è un peccato.
I 4.0 TB in cui è facile annoiare a 83 mm, ma i successivi (più piccoli) 4.2 TB in cui un po 'di incertezze, alcuni in cui solo in grado di andare in sicurezza a 78 e alcuni a 82,5.
Le probabilità sono del 99% Direi che la TB di Bosch funziona allo stesso modo dell'uscita TPS delle TB Hemi da 85/90 mm che ho usato, quindi il convertitore che ho sarà in grado di funzionare.
Il problema è che il convertitore di segnale che uso per adularlo per i nostri Jaguar è costoso (450 euro ish), ma dato che l'unità Bosch è relativamente economica, potrebbe essere un'opzione per alcune configurazioni più impegnative, specialmente se si tratta di un attacco diretto . Gli Hemi's I (da 80 a 90mm) hanno un modello di bullone più largo, quindi richiederebbero molto più lavoro ed è conveniente solo per i setup molto esigenti del flusso d'aria.
Sarebbe bello per la comunità se pinkbatmotorspsorts potrebbe fare un convertitore più redditizio, altrimenti io sono disposto a offrire il mio. [/ QUOTE]

[QUOTE = avos; 1973531] E ho già risposto ieri ;-)
Non ha una TB Jaguar, quindi ti ho suggerito di mandare i tuoi o di comprare una seconda mano a livello locale.
Così prendo esso egli non ha ancora tuffato nelle parti elettroniche. [/ QUOTE]
He had written to me that he had bought a used one but when he arrived from the seller he found out that it was not the right model for 4.2L.
I can not send it to him because we have to rehearse as soon as we turn on the new 4.8L engine (it is now missing a little)

I have a question- how smooth is the idle of your set up with bigger throttle body COMPARED to stock?
A good way to assess this is to put your hand on the steering wheel and shifter knob during idle and you shouldn't be able to feel vibrations through them.
The reason I ask is that the throttle body size effects this as our cars use the electronic throttle to control idle and during development there was always this compromise of WOT outright flow vs idle speed control.
For most it doesn't matter, for me however, I want my car to be as smooth as possible (already I dislike the mina gallery intake tube and XKR 4.2 power flap due to the noise- so I'm looking at recalculating the Helmholtz frequencies/quarter wave of the bigger zip tubes). When I go for more aggressive cams with more overlap, this could exascerbate the situation. Therefore I may settle for less than 90mm, may be 82-85mm, although I haven't decided yet.
Are there bosch throttle bodies that are in that size range that have the same bolt pattern?
Thanks
