Biggest streetable Injectors

[The Kansan]

Im in the process of building a motor and i was curious what some of you built motor guys are running for injectors. Id like to be able to drive it as smoke free as possible and occasionally tow a trailer. Where do you think 65% over injectors would get somebody horsepower wise?

I've seen several guys say tuning 100 overs is the easiest

I have 100s and they are clean as a whistle on my small tunes. I would think LB7 65% overs would put you over 900hp if you pushed them.

pretty sure Dustin @ ATP made over 1000 with 60's but was leaning on them pretty hard.

Would 2 stock pumps hold rail pressure with 100 overs?

 

[Dozerboy]

2 stockers are good for 1200hp iirc

depends on the pulse width you want to run


45% over injectors have made 1000rwhp track proven with enough turbo. no reason 60/65% overs cant if you have the right turbos.

i run 100% overs on my dd/tow rig. they are not as clean as stock injectors but they are no worse than the LB7 45% overs i use to run (have a LLY top end now). its going to take tuning time to get them dialed in just right but many tuners have dealt with 100% overs in many different configs now that they should have good bases to go with.

I have an LBZ pump and an LLY pump with 100s and it doesn't have any low rail issues. I am pushing them with big pulse width too. 1125hp at the wheels on a 90* day.

250's :thumb:

I have 250s with 2 stock pumps and no issues with rail pressure yet.

Just looking at what injectors I'll need to make 4 digits with an s475 and what kinda pumps. Was thinking 100s and another SuperSport pump. Didn't mean to derail the thread:hug:

I'd go at least 150's. two healthy stock pumps will do 1000

I have 200s on a single 12mm, no problems holding 29k rail pressure. A little smokey on the street till you learn how to drive with big injectors.

Streetable can be a loose term. Some guys streetable is way differant then others.

I am running 100s. Runs good but they haze and tend to smoke a good bit more than when i had 60s. It does take a different style of driving to not completely smoke out the road.

 

[onebaddmaxxx]

100s are like the new 30%. Mark has my lbz about smoke free with them. I have 200s for it and I run a single 12mm.

Thanks for everyones input. Sounds like 2 stock cp3s and 100 overs should work well.

I'm gonna be running 100 overs and dual LBZ pumps whenever my motor is done. Hopefully it'll be done in a couple weeks.Ill come run around Topeka when it's done lol

Hell yeah. How far up north is Horton from Topeka?
