Technical Punto 60 Tb

[bozothenutter]

Hi, can anybody point in the right direction for a partno (and it's location) of a Punto 60 Tb (32mm)

 

[PRiiM3]

you can pik those up from your local scrappy or off ebay

 

[bozothenutter]

I'm having a hard time finding them at a scrappy (scrap industry here in holland has need of private individuals.....)
I have found two on Ebay, but remember reading somewhere on here that some Punto 60's came with 30mm Tb, hence the request for a serialno.

 

[PRiiM3]

Ahh well i have a thread on here some where and the good guys of the forum pointed out the sizes of the throttle bodies for me ill post you the link if i find the thread
cheers

Punto 75, isn't that MPI?

and I think 38 will be too large, my car is an 899, so i guess a 32 will be plenty large (don't wanna shift all the power to the top end...there is little enough of it anyway...)

 

[PRiiM3]

ahh ok then well its best to ask one of the other guys about the power and if they fit the 899cc witht the punto 75 tb you use the standard top with the injectors on and swap it witht the mpi top

32 on an 899 is quite an increase. Remember its area thats important, so use Pi to work out exactly how much more area you get with only 2mm extra.

I don't have a 32 handy in my office but why can't the vendors measure them?

The number on the tb I have in my hands now is:

32 MM 13
1374 OS A

It is from a punto 60 engine and measures 32mm.

been looking around at how to determine TB size, and found this:

I also found that sheet not long ago:

Have you filled in in for your engine yet? I am curious what figures it will come up with.

 

[bozothenutter]

Haven't been able to find the valvesizes online somewhere, but with the basics filled in it shows 33 something for max velocity.

@rallycinq:

706.86mm2 vs 804.25mm2 not THAT big an increase is it?
only about 14%.

I am sure you wouldn't turn down a 14% pay increase.

I'm thinking about the bob now, might need an increase on that too....whwre do I source one?

Not unless you are going over 80bhp (UK measurement) 79PS or 60KW seeing as you're not in the UK

I have been told the bob in the picture below has a larger diameter, it is from a fiat palio (P75 mpi engine though but it should fit a spi tb).
