Default White Bosch 3's

Today I bought these:

Bosch part # 0280155811 from a Supercharged Pontiac. I believe they are 42lb @ 58psi, and White colored.

All new o-rings and filter baskets, and flowmatched to within 2%.

Thoughts?

These are going on a cammed only (for now) car. Just wondering if anyone has run this particular injector and what their impression was.

C'mon guys. "Fueling and Injection" isn't dead.

When the ASA spec engine program was alive, I flowed and cleaned many sets of them. Never a problem.

Great news. I appreciate it.

After pricing the Green Giants, I never thought 42's would be in my immidiate future. WOW the price on those. Now I understand what the "True Cost of Forced Induction" means. I kinda feel bad for the FI guys, LOL.

Any updates on running these? How'd they perform? How did your car like them? I'm gather a set to run now.

A little late to the party, sorry.

Car loves them. Geoff had them tuned in 5 minutes. I'm at 77% duty cycle at WOT. They're perfect.

I am running them as well. I got them off ebay for a steal. Prices have gone up since then but still reasonable.

I tuned them using the Excel sheet which floats around the internet and ran them that way for a long time with no issues. Later a member on here emailed me more detailed tables for them and I made those changes but didn't notice anything different in how it ran.

They are 41.5# @58psi if I remember correctly.

The spreadsheet is at the bottom of post #1

You input the ratings for the injectors and the fuel pressure and it calculates the IFR in an EFI live copy pastable format.

Thanks for that! I'm sure Geoff got it dialed in perfect, but if I can show him this when I go back at a later date (new cam here soon) it might help a tad.

When I put that part number in ebay it came back with 36lb. Is there something different about them or does the flow rate changed when used with our engines?
