Opions on next set of injectors

[baderic03]

Should I go to a 350/200 or 450/200

Truck is staying on fuel only looking to make over 600rwhp on fuel only And the truck is driven and sled pulled nothing else

Are you upgrading the turbo at the same time?

 

[DieselFreak92]

I didnt even know anyone made 450cc injectors

 

[jwlandry]

300/200 will get you 600 easy

 

[Magnum PD]

I should go with them^^

 

[baderic03]

450/200 nate at unlimited diesel Up grade my turbo to what I have a s475 on the truck

 

[PSDEng]

I have over 600 with 300/200s with more left in it....go with them

400/400

Something in the 350/200 range would be the best "all around" injector. The 400% nozzle needs a lot of tuning attention specific with each truck.

Intercooler may help ya some too.

 

[baderic03]

truck aint getting a cooler its getting 3.5in pipen along the front and back up to the motor the truck dont tow it dont plow its gets daily driven and sled pulled. im not going to see a great enough gain from a cooler to justify spending the money on one.

the truck is going on the dyno today at the shop with the new s475 on it and my 250/200 so we will see what it does if its any were in the 550+ rwhp range the goal will be 700 on fuel and i wanna keep 200% nozzles to keep drivabilty and idle as nice as possible

You should drag race your truck to back up some of these HP numbers.

no worries it will end up at the track when my trans gets built and i get my new converter for it

 

[baderic03]

truck is getting the trans built next week and then it will be ready to hit the track and sled pull competively

 

[SouthFlstrokin']

400/300 imo

 

[97BambiBasherPSD]

Well if your gonna competitively pull it then why not run the 400/400? I mean the tuning has come a long way and you know your gonna want some room to grow if needed. Might as well just buy them once and be done. There are a couple guys that daily drive with those injectors without any problems

Where and what kind of dyno are you guys getting.these numbers on? Bill at php eked out 560 on a set of 250/200s. Is a 200%nozzle draining the fuel to the point.that a 300cc inj is going to gain anything over a 250? Im not.being a dink just wondering.

My truck dynoed 405 with a 175/80s, 38r, a bosch high output fuel pump, and no wastegate/ebpv system. Ive since added new fuel lines(need to do rr and in tank mods/aeromotive fuel pump), and 100% nozzles, ditched.the 37x13.5 for a 35x12.5. The truck runs good(could.run better) and shifts great since I.dumped.the 37s. I would say 35s are the optimum size for my truck. 37s= huge drag. This is a bit.of.a.derail, sorry op, just wanted to.participate.

I got my numbers from Bean's dyno, I think it's a dynojet. I tapped out at 622rwhp and 1300ft/lbs. The truck had more in it, but it started to rain and we were tuning outside, so we had to get the dyno back into the trailer. It was disappointing because we finally started to make some progress with injection timing delay.

Ive heard beans dyno #s are a tad high. I dont have the experience.of.ever.having dynoed there but many have. That injector size is.potent either.way.

 

[PSDEng]

I don't have a reference point on another dyno so they very well may be high. But either way that's the number I give to people....
