What makes the ID ones worth $100 more? I know DW got a bad name from some of their side feeds, but the top feeds seem decent:confused:

Those look like the same Bosch injectors. ID creates a set matched for flow rate and dead time, which is better from a tuning standpoint and low pulsewidth performance.

Cool. Hadn't seen either of those before, had been looking at getting the radium conversion kit but its a truck load more than either of those, 300usd before even getting injectors

It's actually not that much more after you price out everything. With the same equivalent level of hardware as the ID and DW kits the Radium fuel rail kit comes out to $250 msrp/ $230 market. Then add your DW1000's ($380), EI1000's ($380), ID1000's ($470) or ID1050X's ($520). So that give you a base price of $610 DW and $700 ID.

 

The DW1000 conversion kit is $585 market, ID1000 kit $670 market. So they are in the same ballpark. After you start adding lines and fitting into the mix and they all get pretty pricy ($200++ for lines and fittings). The IAG V2 rails are another option to look at as they support fairly low cost pulse dampers, but you'll have to source the sidefeed adapter portion.

They are exactly the same Bosch injectors.

 

I've worked with the ID725, DW750 and ID850 versions and they all work better than stock IME. The DW items are also flow tested and come with data sheets. The difference is that DW actually seem to use gasoline for testing vs. some 'standard' liquid that doesn't help in the real world. ID numbers are up to 15% off on gasoline sometimes (ID1000) and latencies are very optimistic as well. Their scaling data is really only for the Cobb platform while DW's numbers are a good starting point for Opensource guys. So I'd say if you're self-tuning via Cobb tools (which is fewer and fewer people since they are now taking the tools away from privateers) you may find it easier to tune for the IDs and if you're Opensource you should take the DWs. If you have a pro tuner then buy whatever he suggests as he will have his own scalings from previous work and you'll make his life much easier.

ID latency has always been spot on for me first flash. DW from a latency standpoint generally does not match their data sheet in my experience. That said, sidefeeds up to 850cc perform and idle ok. Larger than that and it's best to convert.
