    Injector Question

    Is there any problem using a single hole 80lb injector vs the 4 hole wide spray 80lb injector? What is the difference? Are the ones in the online store the 4 hole type?

    IMO the 4 hole bosch are the way to go. More thorough piston cooling = no hot spots. bosch vs siemens

    I have a massive conversation on here about injectors about a year back. I would never touch anything but bosch injectors(price/performance). The pulse widths are far better and the spray pattern cannot be beat. The reliability and consistency is also better with Bosch. Siemens Dekas are not too bad either. However, Lucas injectors are problematic and the company themselves can't even give me pule info on their own product.

    Stick with the green giants. This is coming from about 8 years racing 3800s, R&D and about 10 engines. I played heavily in HP Tuners with IFRs and offsets.

    Do the 80lb siemens in the online store have the wide spray pattern?

    Definitely see the difference between the spray but can't seem to find bosch 80s for the siemens ecu unless I use a ev1 to ev6 converter?

    So I just received my 80lb injectors from the online store and they have only one spray hole. Look like the same ones I bought online before for like $50 ea. Is there something different inside that makes them spray differently?
