"Custom throttle body overbore from 65mm (3318sq mm) to 70mm (3848 sq mm) Roughly 16% more throttle area. Should be combined with 3in throttle bend and larger delivery pipe on high output cars."

From Genuine Saab. Is this something worth considering if you are stae 4 and have all of the hardware?

Last time I talked to Nick T about it, they dont do it anymore. From what he said, it didnt make any appreciable differences. I dont think there will be any difference at all, especially not for stage 4.

I thought the machining was only done to match the bigger 2.5" delivery pipe and throttle body inlet.

Thanks.

On a stage 4 car the throttle is not a "major" problem. On the 2.3i and very high output cars it is different.

At what point would you say it would begin to make a difference? Also, would the current tune need to be tweeked to account for the larger TB?

when you had a larger motor than a 2.3 4-banger.

guys run twin-turbo LS1 motors through 3" intercooler / intake piping. You'd have to have a turbo the size of a 5-gallon bucket and rev to 20krpm to push enough air out of a 2.3 to "clog up" the factory throttle body.

Rudedog · 07-29-2009, 09:31 AM

Guess that answers that question. Maybe I'll spend the money getting my car detailed instead.

VI009DZ · 07-29-2009, 09:41 AM

Twin-turbo LS1 in a 1992 Typhoon with twin Borg Warner T04's and a 78mm FAST throttle body. If you can force dual-screws, being spun by a 350, through a 78mm body with ease, then we've got nothing to worry about. Ever.

Rudedog · 07-29-2009, 09:45 AM

That looks great. Do you have a pic of the whole car?

VI009DZ · 07-29-2009, 10:03 AM

only one crappy one where its still half torn apart. This is not my vehicle, unfortunately.

Now, tell me that thing has a T-56 in place of the automatic and it is AMAZING.

700R4 is long gone; its got a built 4L80E. T56 is a tough tranny for a truck like that. There are only 2 or 3 Syclone / Typhoons out there running manual trannies. I'm not 100% sure why that is, but it seems to generally worsen the driving experience in most opinions.

There is one truck I know of that runs a T56, but he's also running an Eaton supercharger, in addition to a single turbo.

AWD
6-speed
turbocharged
supercharged

...............weird. and pretty ugly, but apparently its fast as hell.
