Title: Greddy Elbows.
Post by: Tiger_kpt on April 11, 2007, 03:08:51 PM
Just after a bit of advice and info on these.
 
Firstly, there are two variations available. The standard Greddy elbow and the Greddy elbow with a BOV flange on it.
 
Now I have a Greddy Type RS BOV kit ready and am going to be buying one of these units.
 
But what would you guys do in terms of mounting the Greddy BOV? I noticed that alot of people mount their BOV\'s off the first turbocharger\'s hose near the air filter/intake units. Therefore only functions off of the first turbocharger of the twin turbo set-up.
 
If I was to buy the elbow with the BOV flange on it and mount the BOV on there instead of the usual place. Would the BOV work with both turbochargers?
 
What are the advantages and disadvantages of using such a set-up?
 
Which of the following would you recommend? ..... and why?
 
Greddy elbow with flange - mount BOV on elbow.
Greddy elbow w/o flange - mount BOV off first turbo.
Greddy elbow w/o flange - mount BOV off second turbo.
 
Also what gains are there from using Greddy\'s elbow and BOV? Any if at all in terms of performance, response, etc? Obviously they look nice.
 
Was thinking of using Greddy hardpipes (for use with standard intercooler) and mating them up to the Greddy elbow and standard intercooler. Any advantages of these? Or again, just purely cosmetic?
 
Thanks all. ;)

Not sure m8 lol i know the straighter you can keep the pipes the better so, loads of join will reduce airflow? i think lol

Hmmm. I\'m more concerned about the positioning of the dump valve. On the elbow or not?

Just wondering at where my options are with regards to location of mounting the dump valve on the engine set-up.
Where do you guys have your BOV\'s mounted?
 
Any of you have the Greddy elbow with flange or without flange? What are your opinions on the product?
