rebuilding for 550 hp.

lincolnlocker · Mar 27, 2012

so basically my injectors are to small to utilize the bigger nozzles?

PowerstrokeJunkie · Mar 27, 2012

A better way to say it - your injectors wont make good use of the increased nozzle capacity with only 170cc

lincolnlocker · Mar 27, 2012

aahhhh thanks. makes more sense now...

so would i be better off with 100s or 200s if im not towing and want to make 450+

100

I think all this injector an nozzle talk should be moved to a new separate thread instead of derailing the op's thread. I'm also curious about nozzles myself, I've been going back an forth between putting 200% nozzles on my current sticks or just getting a set of 300/200s

Charles would say there's no reason for smaller then a 200% in any application. But again he does his own tuning. Basicly intensive live tuning by a competent willing tuner is a must.

i don't mind it at all, i'm learning more than i thought i would. I'm just glad its a topic that will affect my build down the road. I"m considering 250/100's for my truck considering i do alot of towing. i'd rather be able to utilize the injectors efficietnly because i won't be able to get it live tuned. Unless Beans or TW comes in my area

Doesnt one of his trucks have 300/100s though?

Believe so, but I think he said that's only because that's what was in stock (I want to say Swamps) and he needed them right then.

Groomzybanshee · Mar 27, 2012

Makes sense.. I'm not saying a 200 nozzle isn't has good when tuned right but for most people that are just having there chips sent off and burnt 100s are Sufficient..

Yeah its a 450 with a.38r. I remember clearly its.set.to.run @300hp all day. The inj's are irrelevant other than the egts are LOW due to using that size nozzle for that power output. His red truck with compounds has.400/400's.

TyCorr · Mar 27, 2012

Fwiw, Curtis is.making cool, easy power on PMRs with 250/200's. Lower egts than stock with more power and less of everything.bad. Buuuut he.tunes it himself and runs ultra low injection timing and is.very particular about when fuel.comes in. Id.say.use a person who engages you in conversation when you say "I wanna run 300cc inj with 200 over nozzles. If they tell you they're bad then you probably should find a different tuner, rotb.

so, with a full motor rebuild and ofcourse all the proper internal supporting mods and enough fuel, what would be hp/torque range for my s366 and a set of 250/100's ?

PowerstrokeJunkie · Mar 29, 2012

I would say 525-550 is about the most you'll get out of a 366 on a 7.3, I've heard that from quite a few sources and I proved it myself

Vader's Fury · Mar 29, 2012

what was your torque?

Cloverleaffarm · Mar 29, 2012

i guessed that would be around the hp area. But Vader asked my next question? And also, would the turbo,tunes be able to clean up that much fuel without smoking out the road/running to hot when i tow?

PowerstrokeJunkie · Mar 29, 2012

We don't want to discuss that

the trans tuning on my chip drops out of od easily to prevent the engine from lugging down low, exactly what you don't want on a dyno, so they had to START the run around 2250 rpm and by that time I had probably already passed the peak torque by the time the power comes on.. need me a dyno tune.
