** What is standard boost for a 4AGZE?? **

[waternolo]

As above,

What should the standard boost level for my MAP sensor 4AGZE be?

Please find attached the boost readings taken from the dyno run. Car is running 0.6-0.7 bar of boost. Is this more than standard?

8-10psi.

which is what you have.

So from the graph above is the car running standard boost?

yeh, but why is it so jerky ? ill look for my dyno hub print out, and see if the boost is all over the place like that.

just checked my hub dyno print out and it doesnt have boost.

have you got belt or clutch slip ?, you could mod your abv, to get 1-2more psi. just search, ABV 4agze mod.

I have belt slip at high RPM's, ~6800. I'm getting a 175mm crank pulley installed during the week and just wanted to know the standard boost rating for the MAP sensor 4AGZE.

Any reason as to why the boost is so all over the place? Beside belt and clutch slip?

nah, thats pretty much it (tho it is jerky from the start ? it should be smooth). you will have to do the abv mod when you get ya bigger pulley, as the abv will just bypass the extra added air.
theres a member on here (sorry if i got ya name wrong) terraoprative ? he's played alot with gze's, he will chime in about the abv mod, i bet his ears are burning now.


have you got a mechanical boost gauge in the car ? how does the boost act on that ?

[waternolo]

Yeah I've spoke to Terra a few times via PM's alright. Getting a 175mm crank pulley installed during the week and the ABV Mod is getting done at the same time.

No boost gauge in the car as of yet. Hoping to get one installed over the winter though. Dyno run was carried out on a very reputable tuner's dyno so I'm sure it's correct.
