120# injectors good enough?

[434nova]

I am looking to make 600 to 650 rwhp on e85 are 120# injectors good enough or should I just step up to 160 # injectors.

Made 600rwhp at 20psi with lots of injector left on 120s. Even ran 20psi on e98 with injector left.

160's for higher goals.

How streetable are the 160's ? Do they foul plugs ? Any issues with daily driving with them ?

Nope.
Just get the SMP's from one of our vendors. The precision's are good too, but expensive.

Sorry but what are smp's ? Is that a brand for injectors? Thanks

 

[TT/Ameasap]

Yes

Any idea why precision is so much more expensive

Standard Motor Products. You've probably bought electrical parts for a vehicle that had the word standard printed on the box. Same company.

Consider going with 160's they should give you plenty of room. I hear they run fine especially on e85 as more fuel is needed. I most likely will be stepping up to them this season.
