see, there ya go i was wrong again
didnt really see any sort of chart (with csa n such) but i only looked at the first page
the chart from the first gen site looks something like this:
stock 1st gen inj - 6x.009" = .000380" total cross sectional area
2nd gen 215 tips - 4x010 = .000314(17% smaller than stock) and/or 5x.009?
non ic inj - 4x12 = .000452 (19% larger than ic inj)
185's = smaller than stock
190's = smaller than stock
230's = ?
300's = ?
ddp stg III = 50 LPM (liter per minute) 5 hole extrude hone inj
330's - 5x11 = .000474 (20% larger than stock)
2nd gen 370's - 5x12 = .000565 (48% larger than stock)
ddp stg IV = 55 LPM (only 10% larger than stg III's) 5 holes <.013
pods - 4x14 = .000615 (62% larger than stock)
2nd gen 435's - 5x014 = .000769 (twice as large as stock)
custom injectors -
6x13 = .000795
5x15 = .000882
6x14 = .000923
5x16 = .001005
6x15 = .001059
5x17 = .001134 (300% larger than stock)
6x16 = .001206
5x18 = .001272
6x17 = .001360
5x19 = .001416
6x18 = .001526 (400% larger than stock)
5x20 = .001570 (josh ayers custom p-pump inj)
6x20 = .001884 (500% larger than stock)
5x22 = .001900
5x24 = .002261
6x22 = .002280 (600% larger than stock)
you can tell its for first gen stuff cuz (and old) they dont even have 5x.025 on there
the nay sayers prolly convinced the author from updating the chart
in the lovely way that they do...[/QUOTE]
I know that you are already aware of this, but for the benefit of others, size is not the only consideration. Measuring the holes will only confuse things because alot of injectors are flow matched by light extrude hone. The holes will measure the same, but they will make more power and/or smoke.
