What hp will it make?

[Timmy]

Getting ready to install all my parts on my 7.3 and curious as to what approximate hp I'll be at, as to not be disappointed when it's all together. This will be my dd but only put 600 miles on it a month, the occasional drag race and sled pull. I plan on having it live tuned, but will the injector/turbo combo be potent for another windows 7.3? Thanks for the help guys

550-620.

I'm really interested to see how the 400/400's clean up on a live tune for every day driving.

 

[TyCorr]

550-620.

Based on the amount of air?

 

[alradco]

In for updates as well. That should be a nice DD!

 

[thumbo88]

let us know if you ever dyno it

 

[littleredstroker]

I was told that 250/200s and a 67.7 would make 600

 

[Timmy]

550-620.

What's the limiting factor in my setup?

 

[spongebob915]

I would just get 300/200. With the srp and 300/200 you will be close to 600.

Your bottom end and block. HPOP might be an issue. Did I miss who you're using for a tuner? Live tuning is absolutely the best way to go.
Good luck with your build. :ford:

I plan on using swamps to live tune since I have their injectors, but I have a hydra with PHP custom tunes for now

 

[DocBar]

550-620.

Hmmm. I thought the 468 would flow more air than that. I was under the impression 650+ for a 468FMW.

 

[Timmy]

Would a s471 or s475 be too laggy on the street with the zf6?

 

[Arisley]

Everything is laggy with a ZF6.

With 300K on it, have you done a compression test on it? Have you checked oil pressure with a mechanical gauge?

If anything is wrong with the bottom end, it will make about 525 before it hand grenades.

 

[dieselmandustin]

I would not think that an srp would run that injector to full potential. To me that would be your limiting factor on hp. But then again a stock bottom end won't handle 400/400's but so long til it gives up.

 

[Baker42]

a 400/400 is a bit to risky for me as far as reliability goes. The holes are large and are in close proximity to each other. there for prone to blowing out into a really large hole.

My truck ran 12.9 with 250/200's and S468.

I was wondering how much nitrous would be safe with an S468 with no waste gate ?

I've never ran or rode anything with Swamps tuning, but they are one of the best shops in the country.

It's hard to go wrong with PHP tunes. In my personal experience, Gearhead tuning is great. You should consider them.

The more laggy it is, the less chance of breaking a stock forged rod right? Compression test was good, very little blow by. I won't be running the race tune all the time, but want the power there whenever I "need" it lol

A s468 fmw will outflow a box s471.

I wouldn't run 400/400's with a s468 without a wastegate.

Smaller exhaust housings help spool a turbo faster.
