1: basing any experience of quality injection components from industrial is a joke. Flowed or not.
2: the question of who does good quality injector work was asked. The answer is, quality shops who have a good rep and flow test everything they send out without being dishonest. Eg. Rcd, mpd etc. Anyone who doesn't test is just guessing. Period, end of discussion.
3: if your that worried that you can't trust the shop then by all means have them flowed third party and pay for it. But when I buy them from one of the above mentioned shops I don't have to. Because I know they are right. I don't have to second guess. That why they are reputable, didn't get there by having problems over and over.
4: rcd's injector quality at one time was not the best, like many other second rate shops. What happened? Oh yeah they got a flow bench and quality has drastically improved. Hmmm.....
5: Steve gets a little worked up at these threads. They keep becoming commonplace. "I wanna know who's best, but if you mention any big names then your just a nut swinger". Go buy whatever the f*** you want then, don't listen to guys who have bought 10 to 100's of set of injectors. We don't know anything I guess.
6: any one can theoretically build injectors. I've done quite a few myself. But you know why I don't sell them. I don't have a $50k test bench to back up my quality. I can, and have sent them out and flowed them. Even sent some to rcd. But in the end it's just not feasible to have the quality and productivity to match what some of these shops do without full time injector builders and flow benches. That's why they are good at it and have a good reputation.
7: not all "big name shops" are better, see eg #1 ^^^^^. That's why you asked and we recommended. We've been over this, ten of hundreds of times. But then again I guess we are all just nut swingers because we like our quality tested injectors.
8: once again, like all the other threads like this. Someone will still end up being hard headed and go the other way, just to find out that it didn't work and they should have just contacted a recommended shop. Like ones stated by all the "nut swingers".
9: there could be exceptions based on complete accidental error like mis-packaging that invariably will happen. Human error could alway be a culprit. But generally speaking I have heard very little (or none) horror stories from the "quality" shops sponsoring this site that flow test their injectors. But I would test them if your still worried.
10: if your still reading this by now, then have a nice day! (Didn't have anything else for line #10)
