ok, so, would a K24 be any good as a low pressure turbo with a VNT17 as the HP turbo? or are they too similarly sized to be any good in a compound set?
-
KKK turbos are very inefficient, its best to avoid them in any situation.
-
ok, well i didnt ask for you to tell me they are inefficient. i could care less if they are or not. but if i can run it with the turbo i got, and have a little more fun, im down for it!
-
Ok, well you asked "would a K24 be any good as a low pressure turbo" and I gave you the correct response, avoidance. Piss off child.
-
anyone have any worth-while info as to why i should or should not use a K24 as a LP turbo and a GT17 as a HP turbo?
-
::) I think you two should kiss and make up. oh, and gimme the vnt-17, I've got an engine i wanna try to exploderate. :D
-
Put it on and see how it works.
-
so if i have the VNT with 20 psi, and the K24 set up with a stock WG setting of 8 psi? what am i looking at for a total pressure? enough to blow the head off my engine?

= (20+14.7)/14.7 * (8+14.7)/14.7 * 14.7
= 2.36 * 1.54 * 14.7
= 53.4psi
I'll let you decide whether or not that's enough boost ;)
-
If you take the boost reading form the intake manifold you should be okay, I'ld watch the gauge though.
-
20psi is what you would get. The VNT will keep manifold pressure the same, it will simply open the vanes more to reduce drive pressure.
Oh thats right, your vanes are "wired open". In that case you would get 53psi, far more slowly than with a functioning VNT.

Depends on where the wastegate is referenced and how much it can flow.
-
There is no wastegate on a VNT. All the exhaust flows through the turbine.

That is interesting, last time I checked a K24 isn't a VNT.

Howsabout everybody simmer down and remember that:
1) these are just cars and engines... nothing worth duelling to the pain over...
2) we're here to learn from each other and share information, not prove who's the smartest or best endowed
3) the forum guidelines call for respectful posts at *all* times.

I agree with Tyler. Kevin i suggest you PM Matt (RadoTD) and ask him. He has access to a lot of turbo maps. he has done extensive research into compounding with KKK turbos and all sorts of others, including VNT's.
