I'm wondering what the differences are, and in general (flame suit on) which is "better"? More specifically, what would be the benefits/drawbacks in changing from IDTP-->IDAs? For what it's worth, this isn't something I'm considering doing, it's something that's already been done on a factory /6 I'm looking at. I have the opportunity to purchase the IDTPs in addition to or as a replacement for the IDAs, but have been told the engine is running very, very well with the IDAs. I like the originality idea of sticking with the stock carbs, but don't want to sacrifice performance or the convenience of a more modern, more fully developed product *if* that's what the IDAs constititute.
Basically I don't know shit about carbs. Yet. (IMG:style_emoticons/default/smile.gif) Any and all feedback (opinions even!) would be appreciated. Thanks all (IMG:style_emoticons/default/chowtime.gif) edit: Replaced "40s" verbiage with "IDFs" in an attempt at clarity re-edit: Replaced "IDF" verbiage with "IDA", since that's what they actually are |

factory 6's were all carbed
the difference would be the number on the outside of the carb are just not right for a number matching car I wouldn't think there would be any difference in performance and even the numbers not matching should really produce no difference either I suppose in a full pro concours maybe.... but for practical purposes... no difference I don't know the minute differences between the T and A I do know the IDS carbs had an auxillary enrichment circuit for high rpm they only made that carb for 2 years (and none on 914's obviously) even that is a minute difference, but one could argue it is a performance difference at least. from a realistic view: my guess is that the original T carbs were getting worn out, and since they cost 1k to have rebuilt propperly, it was cheaper for the owner at that point to put on a set of IDA's than to rebuild them.. its the throttle shafts that wear and no rebuild/self kit addresses that issue. your choices are between 800-1400 to have it professionally addressed. brant |
