yes it will be turboed but now I am stuck on what injectors to go with… i ran dsm 450 before on a different motor but dont know if those will hold up, what do u guys think? Will those be ok or should I go with something better?
Im lookin for around 450 possibly Hp
A rule of thumb is that you can never go wrong with bigger, 450cc will not net you 450hp so I would suggest 880cc or above. 680cc injectors are around 120hp per injector but that’s at the minimum. I would go bigger, possibly 880cc(151hp per cylinder) to allow you more injector plus there the largest injectors for the price of $279 a set. or 1000cc(171hp per cylinder) for $299. these are precision injectors. there are also 1000cc Injector Dynamics injectors witch are better but there about $400 a set. its your choice.
As already said. 450’s are way to small for 450 HP
something like 1000’s should do just fine. I never run an injector at more then 75% of it’s duty. It’s way to hard on the injector and they will not last as long. So no point in cheaping out to save yourself a few bucks. In the long run you’ll end up spending the same.
Precision’s 1000’s are good and have been proven to be reliable. Problem is they idle like sh*t when tuned properly and are even worse with any kind of larger cams.
I would highly suggest the bosch 1000’s (aka ID 1000’s as Injector Dynamics just renames them as their own). These bad boys idle like a stock car. They are by far the best injector I have seen in years. Size is super thin and the kit comes with the correct adapter sleeves for them. Amazing injectors when compaired side by side to the precision 1000’s. They can be had for a little more then $400.
In the end you’ll be so thankful you picked the ID 1000’s. Trust me! Been there, done that and won’t ever go back!
Get 8800cc
I second BBP-GS
I’ve heard nothing but great things about the Injector Dynamics injectors, both locally and on the forums. I wouldn’t hesitate to slap those suckers in
do some calculations… http://www.rceng.com/technical.aspx
450s can take you were you want to go, but your going to be hurting them to get there. the injector is flow rated @ fuel base pressure. meaning at 40 psi (fuel pressure) they sit at 450. but with 50 psi (fuel) they are now 500s. at 60 psi they are 550s, and so on a and so forth as base fuel pressure is increased. keep in mind that OEM regulators are a 1:1 ratio.
a suggestion is that you dont run more then 90% duty cycle on ANY injector you choose to use. this is the suggestion you will see from most injector maker, tech reps, and tuners.
in my opinion, 880 cc injectors will be enough to meet your needs.
