Whats the real world benefits of a ported head? Also is there really any need for a wot box on our cars since they have boost instantly?

 

WotBox is nice due to 2step features and the NLS feature. My slips at the track are so consistant due the box.

 

Ported head helps yes! ... Wot box for the two step is fine and dandy but I my self don't trust retarding timing to the point of having two step. My 2 cents...

 

Whats the hp gains for the ported head if anybody knows? Also whats 2 step sound like on an lsj? lol youtube blows

 

Here is a 2step vid set at 3k.

Sounds sick lol

 

Watch afr.. lol.

 

I know I prolly wont get one.. my car has enuf problems

 

gains of a ported head will vary with your mods.

Yep Bad Sensor will cause this, Not a issue anywhere else, lol Anytime i went WOT until i changed it would cause the AFR gauge to foul Out.

 

Even if afr is rich its still detonating. So for a dd its not safe .

 

Would like to see dyno comparision with ported head.. either a head or turbo swap is gonna be done by spring

 

I friend of mine dynoed 20 over his last dyno with one of my ported heads, gains can be more or less mods deciding

 

I will have a before an after with a zzp ported head and stage 2 cams compared to stock. Wont be the same day but def the same dyno.

 

Yea if I get a ported head I'll just get everything in i done.. cams, springs, etc.

 

its not detonating, its the fuel lighting off with the exhaust valve open. How good it is for your exhaust valves, exhaust ports, manifold and manifold gasket is still questionable.

 

Yeah ..... I know this....... Since the car is - timing it is a detonation not kr and over time can cause issues.....

 

for the sole fact that 2 steps have been used for many many years with no ill effects your statement is false

detonaton and knock are the same thing

The Causes of Internal Engine Knock, and How to Eliminate it. By Ray T. Bohacz

 

Detonation and knock retard are not the same thing Knock retard is a retardation of the spark timing in order to prevent a knocking condition. Detonation is the ignition of the fuel mixture when it is unintended. Typically we refer to detonation as pre-detonation, which is when the fuel mixture ignites before the intake valve is closed, or even in the intake tract (nitrous backfire anyone?). Though if you werent intending for the fuel charge to ignite when the exhaust valve is open then it would be called detonation, but since we're using a 2 step we are intending to ignite the fuel mixture, just at an unusual time.

 

detonation and knock and pre ignition and predetonation are all the same thing no matter how you word it

 

thanks for info guys would like more info on head

 

i picked up a ex ported head put it on ran better in the upper rpms made 243hp got one of bongs heads and made 263hp it is ex ported only also another guy i know has stage2 zzp cams with a bong ex ported and it is just wow with the tvs

 

So 20 hp from head? and if I do it I'm gonna get a built head.. cams, springs, etc.

 

i would recomend lsjion (akabikkabing on rl forums) you cant get a better head for the price

 

Do u know what he charges? I have friends that own a performance/machine shop
