Does anyone have dyno charts of the skunk2 Intake manifold for a GSR?

 

I would like to compare the gains,because I'm considering staying with the dual stage for everyday driving.

 

I don't know about the GS-R's, but all they do for LS'es is move about 8whp from 4k-5.5k to above 5.5k. The power at 4k-5.5k is as much as 8whp less than stock, but above 5.5k it's as much as 8whp more than stock. Not worth it on a LS, imo. I don't know what it'd do on a GS-R though.

 

The dual stage is good for approximately 180 whp. If you are making close to that and you think the IM is a bottleneck, then upgrade. I wouldn't unless I had bigger cams, and a higher redline.

 

I remember a dyno that Import Tuner had on a 95 GSR with an intake and exhaust. It gained hp in low range and lost a little in mid-range and then picked up again in the higher rpm range.

I hear that you need so many other parts to make this work. Does anyone have a picture of their Skunk intake manifold in their GSR?
Does it come with detailed instructions?

 

i have the skunk2. its nice. it was easy to install.

-sam

 

What other parts did you need? Can you post some pictures.

how much was everything to get installed? i think someone on this board said it costed 750$, i sure hope thats not true

 

its so easy folks! just do it yo self! take off old mani put new one on. you need some new parts for the throttle body, do a search to find that stuff. Search foos

 

750?!?! dang, someone made them grab their ankles.

lemme find my dyno chart b18c1 - AEM CAI and skunk2 mani only.

 

yeah, i wouldn't recommend it on a stock motor.....i have ITR cams now and it feels great

 

i see, thats a funky looking dyno! it dips down then comes back up. Have you gotten a dyno recently? So it should be ok to get the skunk2 intake manifold after i get my itr cams installed and tuned and crap? Do you have any cel with the sk2 manifold?

 

yeah got me guessin too.

anyway, no CEL just make sure everything is hooked up right. but i did throw a CEL after my ITR cam install...im running a little rich and the o2 sensor isn't real happy.
and no i haven't gotten it dynoed sincei got my cams in, but i will soon though.
yeah i think it would be better to get the skunk2 after you get your cams...

 

There are 3 dyno charts there which is which?

 

ill try and get my dynos before and after s2m installed scanned tonight and post them

 

That would be great,and even if someone has the dyno for the skunk IM before and after with ITR cams it would be great.

 

all the same,just different runs...mods are on the chart

 

So its 3 runs all the same with intake and intake manifold?What was your baseline?

 

i never got one and till this day still regret not getting a baseline run

 

Well thanks for the dyno runs,if anyone finds any other info feel free to add.

 

u must be bored dustin. haha

The Skunk manifold isn't worth it.

 

doesnt this disable the 2ndarys, thus a pretty damn good loss in trq downlow? with a good gain in mid, and better high end?

 

I can't believe with those mods that u could say such a thing..
<understand that reluctance/ignorance = slower than me>

Yes, but it's not that big of a deal.. If u want to experience the feeling of no secondaries, disconnect the iab connector or unplug the line running to the vacuum unit/thingy/ufo.. If u want to experience the 5whp (stock), u gotta get the manifold..

 

Yea i may change my mind,but i would rather have more usable tq and hp through most of the rev range,then have more for like 500 rpms,my opionion,same for the header,i would rather have a nice power curve threw most the rev range then the last 500 rpms.Thats were the header and manifold do better then stock IM and 4-2-1,the end of the rev range by a little.Note my car is not a highly modded ride,for modded rides go 4-1 and single stage.
