It's an oem injector so Bosch does not have it listed on their global sheet yet, however, on a flow bench they flow approx 59 @58psi there is all kind of spdata floating around on these. This is what I get.

I'll use the Bosch#.

Great info!
Is there a spec / guide chart as to what "horsepower rating" each injector set is capable of handling?
It seems like alot of guys are trying to go way to big on injector sizing, jut like the old school guys used to try and put huge carbs on small blocks and wonder why they weren't performing as well (ie. 850cfm vs 650cfm)
I feel that would be helpful to alot of members
Thanks, Jeff

Well a HP rating would vary based off BSFC (Brake Specific Fuel Consumption) so Displacement, and weather or not Forced induction is involved would make a difference. But there are at least a dozen injector calculators on the internet made available by just about every injector / fuel pump company.

I have a number 280158051-85, that's a Bosch 85# injector,
that is sold by Fast as part # 30857, as an 85# injector.
But other cross references for this point at the GM part # for the LS3/LS7.
Maybe Bosch has two versions of it?
Trying to find the necessary info to put into HP Tuner for the 85# injector.

Improvement over stock and readily available depending on the power needs.

https://www.psiconversion.com/tech/l..._injector.html good info here, very complete. I tried to attach an excel with this same info along with o ring spacing for the Gen 4 stuff. we'll see if the excel comes thru.
