i got an LS and i got a i/h gonna get an e soon is the next logical step the Skunk 2 intake manifold. and if so are there any significant gains on a LS ? i've done a search but havnet found much i guess i suck at searching

 

i think they have pretty good gains for the money i would also get cams like crower cams and that will def help out and the intake manifold will be more useful too

if you want a skunk2 manifold i know a friend who is sellin one for an ls for about 210 it was used for a week and then he decided to go LSvtec he is acid dippping it as we speak and wants to sell email me at cleggboy@hotmail.com if you are interested

 

get a cat first, you have nothing that warents the need for a different IM at this point.

 

with that attitude and reasoning there is nothing that warrants anything we do to our cars unless they are broken

 

I've heard people actually lost hp\torque with the manifold without having a header\cat and\or cams. Beware

 

you only lose some low end but who runs there car at the low end anyway?

 

i like cleggboys attitude....yeah, why do we modify our cars? me, i do it because i love the feeling of acclearation, shifting at 8000rpm...get a new header, exhaust, or an Im whatever...as long as my car acclearates or sounds better when i'm hitting v-tech...that's why i do the things i do to my car...

 

You'll lose some low end, but you'll gain some on the top. It'll basically shift your power curve.

Mmmm~ Top End.

 

I personally would get cams pre IM.

you modify your car for this?

 

You know he has never popped his hood if he spells it v-tech. That, my friends, is depressing.

Actually, he knows what he is talking about.

It's like getting a VAFC or cam gears for a bone stock car.

 

i ment that when i do get the cat and assuming i warrent the need for a skunk 2 im .. will my ls be able to gain much from it ? like what kind of hp can i expect from it with a i/h/e/c ? and wont it fall short because i can only rev to like 6900

 

What are your goals?

 

my car is just a daily driver but i would like to see a 14.99 one day even low 15's i'd be happy with.

 

Thanks dlo

Yes, its called buying a part that doesn't fit your engine setup (or even future engine setup) so you lose power instead of gaining it.

After you have done i/h/c/e, there really is no need to upgrade the IM or TB until you have done some internal work. Otherwise your engine can't take advantage of the larger TB & IM, and you lose flow velocity, and get worse performance.

Its the same idea as buying a 3" exhaust on a stock engine, your performance is going to suffer greatly because of it.

This "lose low end, but gain high end" stuff that people quote for everything (2.5" collectors, larger TBs, etc, etc) is for the most part hugely inacurate. Going too large is going to kill both high and low, or possibly gut low and mid-range for some very slight gains up top.

You have to pick your engine parts to work together as a system, with peak HP and powerband in mind. Otherwise you are going to waste lots of money and end up with medocre performance at best.

Look into cams, higher compression pistons, tuning, etc

 

Does anyone actually have a before/after dyno for a skunk2 IM? I always hear people saying online that it kills low/mid range power...but when I talk to engine builders...they say the low/mid loss is minimal if any.

 

I have the Skunk2 mani on my daily driver (DC4) with i/h/e/portflow head. Prior to installation I lost a little lowend because of my portflow head. After installation, my lowend remained the same but I lost a little midrange mostly between 4-5.5k (an SAFC and cams will probably fix this) but after 5.5k my car pulls to redline. I hope this helps.

Frosty who is going to kill himself b/c of the work he has to do towards the end of this semester

I have to question how much those engine builders know. They should be informing you the difference between a S2 IM on a fully built motor and its effect on the location of powerband, vs a S2 IM on a motor with only boltons. Not trying to generalize how one intake manifold performes on all engine packages.

 

Obviously the IM will be of greater effect on a built motor versus a bolt ons motor. No one is arguing that. And again, I said that the loss of power would be minimal (as if our cars really have low end grunt ).

Trust me...he knows his stuff. Anyone who drives a 11sec all motor honda knows what they're talking about.

I still have to wonder, lots of people drive fast cars but don't know either how it got there, or copied someone elses setup. If he knows as much as you say he does, I would think he would be preaching building your engine as a package, and how everything works as a system, instead of saying X IM doesn't hurt that much lowend in general.

Its not necissarily just the low end, in most cases it hurts midrange too. When mostly concerned about drag times, it is common to focus on high end in our cars.. but a high peak HP/TQ with absolutely no midrange is going to go slow due to the powerband is being be way too narrow.

 

How much midrange have you seen lost with a skunk2 manifold?

 

I havn't looked through any before and after dynos with the S2 intake manifold specificly, but if you want to know more about how intake manifolds (and which charectoristics) effect the powerband you should definetly read through this article.

It does go over the s2 im.

According to the butt dyno, I have noticed a slight decrease in midrange. I can get it back with cams and tuning. Hope this helps.
