I have a '95 teg B18B with a DC header, and AEM cold air. My best et was a 14.87. Now I have installed a Skunk2 intake manifold and it slowed my car down 9 tents to a 15.7. What is wrong I need some help.

 

what were your 60's and trap speeds for both runs?

 

maybe u did something wrong in the install, maybe the wind was blowing against you, maybe you fucked up on you driving....u need to explain your situation more.

*err, n/m i dont know how the skunk2 manis do on b18bs

 

for real need a detail explanation along with both time slips...if both 60ft were the same and no miss shifting occured.....then skunk2 im slowed u down.....

i think the intake manifold was over kill for your setup considerin it seems to be a be stock motor with header & cai....you have no cams.....or piston or anything....

maybe with a turbo kit you will make power with the skunk 2 im for a b18b

 

The Skunk2 manifold is for more higher RPM ranges, it probably killed your mid and lower range power. Judging by the mods you listed, it comes to no surprise that the manifold would do more harm than good. Gotta research this stuff man. 14.87 with a LS and just a header and intake? Doesn't sound right. Maybe it was a driver thing.

 

Your dissapointed because you got a worse time after you put it on, but I have a feeling that the first time of a 14.7 on a B18B with just a CAI and header is definatley off. How does the butt-dyno read the car with the IM as opposed to before?

 

humm yeah did you pick up the wrong slip for that first run or did you run that 14.8 consistant all day? i have close to the same set up as up except on a gsr and the skunk 2 didnt hurt my times i run high 14s real consistant with a little help from the vtec. 15.7 sounds about right for an ls with those mods im sorry to say. post the slips

 

Is your intake for a Type R. the skunk2 mani is basically an aftermarket type r intake mani. no sencondaries.

 

Intake really has nothing to do with it, the Skunk2 mani is enginered for high RMP uses, with runner length and the plenum size. It'll kill you on a mild set up for a relatively low revving B18B.

 

14.8 with only Intake and header. i call BS! not to be rude, but u will have to have a FREAK motor to do that and the whole car gutted to about 2200 lbs. maybe the clock on the track that day was messed up. theres no way ur doing 14.8 with only those two mods. i ran a 15.9 with only AEM cai and full catback in my LS with perfect shifting and launching at 4K. 0-60ft time was a 2.3

 

i read in another forum that the skunk2 manifold only helps out if you have ajustable cam gears to fix the timing, and it also only helps out your upper rpm. it kills your lower rpm. hope this helps.

 

that manifold doesnt belong on a b18b
its a manifold that brings out the top end power,a b18b doesnt have top end power...without plenty of other supporting mods..

 

the real question is..what did you do to compensate for all that extra air going into your motor? Add fuel? get the car tunned!

We have a smart one here. When you add an IM you really should get your car tuned. Not only that but your mods seem pretty mild to be getting the skunk2 IM.

 

i installed a sk2 mani on my car too it did have a lag towards the bottom end. I think running the stock makes more power on the 1st & 2nd gear. It only made for power with camshafts. i had stock cams and it didnt make much power, but upgrading cams you might feel the power.

 

alright I know the skunk2 is probably to much for my setup, and when I bought the im i knew going in that it may not help me at this point at all. but losing almost a second and 5mph seems like a big drop to me. I think I'm going to put the old im back on for the rest of the season, and wait till this winter to put the skunk back on along with a turbo system.
And yes my car will run 14.8 consistent under the right conditions. Usually Im running 15.0's to 14.9's at about 88mph, my 60ft's are 2.1's 2.0's with BF drag radials

Yea ill call u on the 14.8 also it just doent sound right to me

 

well u do loose power swapping to a skunk 2 IM. u have more low end torque with the stock IM now the majority of ur power is gonna b higher in the powerband.

 

Well,

I installed mine this past weekend...

going under 3k rpm didn't seem like any change.

Today when I Hit VTEC at 5500(I have a JDM ITR ecu) Whoa.... you can tell the difference, as soon as the Vtec kicked in, the rev was way faster, and you could hear the sound! it was Awesome!!!

Anyway, yeah, I know what you mean when you said it feels slower, I guess it depends on your mods, but It did make a big difference for me on the Mid to High end.

I second that call, no way in hell are you running that fast. you'll get that maybe if your not really running at the track. those two mods aren't going to make almost 2 seconds difference

 

i had an ls with aem short ram, dc sport 4-1 header, greddy sp exhaust, with clutchmater stage 1 clutch & lightened flywheel....

on bald street tires manged to pull a 2.35 60ft trap speed 89.50 mph i only hit a 15.3........


and you only have i/h...........hard to believe......

but definately turbo will make power with that intake manifold from skunk......

or maybe an ecu with aggressive fuel map and some cams to beef it up......and high flowin exhaust will also do it

 

ls cant hit that time, unless(stated b4) it was stripped...

my best time was 16.0 with 2.2 60fts trapped at 86mph...

thats like sayin my car with an intake hit 13s....sorrie

 

thats all you did with those mods? when i had the same mods i ran a 15.6 no problem. 0-60 ft was 2.1 and perfect shifting, launching at 4500rpm.

 

oh wait i also had the act flywheel while doing that 15.6 hehe

 

Putting a skunk2 IM on with few mods and no tuning won't do jack for you. Those primaries are too big and will not allow you to get what I believe is called laminar airflow. You need to have sort of a funneling effect to get the most out of that IM. You need at least a header and cams to see the best gains out of that IM. When you are flowing the right amount of air, that IM can make over 5whp. On a stock setup your bottom end will be sluggish. The top end may feel better, but with I'm guessing a 7k rpm fuel cut? Your not going to see the best the skunk2 has to offer.

I don't see how with i/e and some drag radials you are pulling off a 14.8...is it down a hill? A big one? Props to you if you post up a time slip and keep the haters quiet...including me.
