Hey h-t people, well I am about to leave to JHPUSA to pick up a Skunk2 Intake Manifold for my B20vtec setup, but I was wondering would I make good power with this Manifold, or should I go bigger?

Why not give the Performer X manifold a shot? The S2 Pro is nice but not much of a design improvement over an ITR.

well I had a ITR manifold, and I used my friend S2 Pro manifold an put them next to each other, the only thing I can see is that, the runners are a lil longer, and the plenum is just a lil bit bigger but that about it, but I was wondering would I make decent power

 

Can you think of any reason you would not? Its been done.

Well wat I hear from my friends is that ill stop making power at like 6-7, this is coming from Prostreetimport also, but I think imma say f*ck it and see for myself, wouldnt hurt to try

 

Plenty of guys making power on it, is this a street car? Daily driven?

yup street car daily driven

 

it will work. and it will make power beyond 6-7k you are looking into this too deeply.

set yourself goals and then choose parts on those goals.. the skunk2 pro series manifold is a nice piece and the design is proven.


the n/a version of the victorX manifold looks like it will perform but i have not seen testing personally.

i have a b20/vtec which makes 270hp and im running a oem itr manifold that i ported (with out cutting it open) as far as i could reach inside.

shawn

 

I say Performer X, its what I bought. No one has any real comparisons yet, but they have been the first to change the design significantly and I would not think they did that without research.

i agree with you. i was looking at one yesterday and the design looks good. just gotta see some numbers to decide.

i guess they should be right if they wrote a book about it.. all of the engine builders and racers should be running them.. maybe ill get one for my 2ltr..

 

bump!

 

aww come on no help at all , im just looking for suggestions from people who have done a build similar to this

 

Here is my dyno chart from my b20, it has 67-64 t-body, smsp b18 header and an itr intake cam, NON pro series skunk manifold.

 

I think it's damn hard to beat a ported type r manifold. I'd like to see the FR tested against one on a larger B motor though.

 

I went from a skunk2 manifold (non-pro) to victor x and it helped my top end.

See that graph up above that Runnerdown posted, that motor hits max power at 7500 rpm and stays flat till shutdown at around 8200 rpm. My motor did the same with the skunk manifold but with the victor x at 7500 rpm instead of staying flat it keeps on climbing for another till 9500 rpm.

and this is with a 2L motor correct? Do you by chance have a dyno chart with the Sk2 Pro series mani. on a built 2L?

 

import builders someday people will realize these are the shiznit.

 

Here is my dyno. Semi built 2.0L. This was with the skunk2 manifold but not the new pro series manifold. Look at my dyno I hit peak at about 7500 rpm and it stays almost flat till 8500 rpm. To get to 225 whp same dyno too, I changed to a profab header, edelbrock intake manifold and 68 mm tb. Instead of staying flat at 7500 rpm the motor keeps making power to 225 whp at about 9200 rpm. Sorry I dont have that dyno since prostreets dyno's printer was not working and I did not have my digi cam.

so with my build shouldnt I make a lil more power since im using forged pistons and rods, bigger cams etc..? And also will it still peak at the same rpm with the Sk2 pro mani?

Forged pistons and rods do not make more power by themselves. They are just more stronger and will take detonation alot beter than cast oem's.

I dont know how good the new skunk pro mani is. Some folks have said it is the same as the old skunk but I don't know to tell you the truth since I have never seen one in person.

Looking at your build you will need bigger injectors for sure. You need 440cc's.

well eugene at prostreet import recommended 310's for my setup
