Any thoughts on these injectors??

I have the same injector but 62lb. I dont care about fitment just function. Thanks in advance.

 

Why go with an non reputable brand injector? Last think you want is to have an injector fail on you then..... boooommmmm

 

I can not say for sure since the dimensions are not listed, but that injector looks to be the sub 2" style injector that is being used in recent OEM applications such as the LS7 and L92. Even though you mentioned fitment is not an issue it could be useful information for others for me to comment. To use a very short injector like that can be difficult in conjunction with stock fuel rails that are designed around the common 2.5" or 3" injectors. Going to taller injectors than stock is one thing to work around but going to smaller injectors will usually be difficult.

We carry different variations of the "Mototron" Siemes Deka for some of our universal applications and it is a decent enough injector IF they are flow tested and put in matched and balanced sets. The description of that items states exactly what we don't like about those injectors, +/- 6% tolerances, which about what we see when we flow test a batch of them (min 100 injectors). That means that there is an allowable 6% flow rate variance from injector to injector. You really want a set of injectors with at least half that variance. We match and balance to 2% or less. To some people that may not sound like much, buy you don't want one injector in a set flowing significant less or more than the rest.

 

thanks for the reply Mike. I appreciate the info I am still learning alot about builiding engines so all the help is great. They are the sub 2" style you are talking about. We machined spacers so they could be used. I am currently using them in my TT car right now. They seem to work pretty good so far.
