How much power can a N54 make without meth.

Alright so I have apparently sparked a bit of debate on YouTube and would like to clarify something.

How much power can a N54 create without meth.

My answer was basically 350-360whp, which translates to 410-420hp.

With just JB4 and race fuel 370whp, which translate to about 440hp

With full bolt ons, JB4, and race fuel I remember seeing some dynos pulling 400whp.

Please correct me if I am wrong.

JB4 plus FBO you should be in the 400 range depending on what pump gas you are running. If 91 probably a little shy of 400rw. If on race gas and FBO you should see north of 400. Also really depends on the dyno as well.

The above are assuming a DynoJet.

You don't need charge pipe or dv/bov if your stock components are holding boost without a problem

I'm getting 370rwhp with Cobb S2+S, no meth on mustang dyno... you convert that to Dynojet and it's about 420rwhp (12% difference). You convert that to crank hp and it's about 490hp.

You don't need them, but you'll want them on there when you're running high boost & pushing the car hard (drag/autocross/excessive highway pulls)....

dont wanna go limp when its your time to shine

Don't know how much power I am making, but I can consistently trap 116-117mph in the 1/4 mile with just Cobb Stage 2+, intercooler and downpipes on pump gas.

I think this all depends on the tuner. I am making significantly more power(thats all I can say about this) without DPs on a Mustang Dyno, so I can imagine what a DynoJet will show.

However, my advantage is that my tune was custom tuned specifically to my vehicle mods and will be retuned again when DPs go on.
