It would help the turbo yes. People don't realize it much with stock or smaller frame trubos being they already spool pretty fast. Instead of putting the wg air back into the system it blows it off to the atmosphere getting rid of it totally and not just down the exhaust. Stiffer spring in the wg will make the wg hold more pressure causeing the turbo to spool not only faster but keep the power longer not wasteing it.

I don't run one with an ef4 and my car is fine. Will I switch over to it? Maybe I just don't see the need to at this point in time.


I disagree with this statement. The more air you can get out of the system in any configuration the better responce, and gains you will get. Any time you can get a restriction out of the way your gonna get gains even if its minimal.

 

But since i'm going to change the turbo i think that it's much better to change at the same time since i will gaine more power and that's good to know

 

Can you send your stock E9 turbo to be upgraded to save some money.

Or do they not do upgrade.

 

I do believe you can have your stock 9 upgraded yes

 

You would gain more spool then power really.

I believe its on their website but I want to say yes. I am sure Chris will chime in on it.

 

Yes you can, that's exactly what I did.

 

I found the info they do upgrade.

 

Yes sir.... the prices are on their website.. 100% positive...

If I remember correctly its like EF2 ~$1000 and EF3 ~$1400 with your stock9.... its basically a core program if I recall. I did my homework

 

what ef turbo would be compared to an hta green

 

The ef2 - to FP green
Ef3 - red
And ef4 - black

 

that's good then

 

 

from the dyno charts i've seen, an hta green is good for 530-550 whp in kill mode with supporting mods on e85. i don't recall having seen any ef2s make that kind of power, so i'd say an hta green is somewhere between an ef2 and ef3 -- closer to ef3 than ef2.

 

With this info the Ef2 is larger then a green, the ef3 is larger then a red and the ef4 is larger then a black.

 

We are talking reg people not Curt Brown's #s hahaha. I do believe Chris said that there was an ef2 that made over 500 as well.
