a guy with a 2.2 dynoed his and he only gained 9 hp and he said that he lost some acceleration

wdsoccer

they said loss of tq and gain in hp from 4500 to about 5500. think thats what they said

I'm the 2.2 guy GTX was talking about. I lost torque between 3300 and 5600 rpms. At 4 grand I was down almost 20 lb-ft. I will try to get my dyno sheet up this week for you guys to look at. I'm not bashing CED at all, some of the guys seemed to get decent gains with minimal torque losses. However, my torque curve got shot to pieces.

what do u think it will be like for a auto?
i have the gmpp intake a dcsports cat back and soon to come SS/SC DP and Manifold

XM15

It should be the same. I think that the only way a 2.2 will really be able to take advantage of this manifold is if they go with a turbo or a high revving setup.

Here is what I have been talking about:



This is a comparison between my setup without the manifold and with the manifold. Take it as you will; I don't like the results and will be switching back shortly. IMO its not worth the loss throughout the power band. If I want more power higher up, I'll consider cams in the future.

ok so from you expericence is it worth it for me to put it on? right now i am beatin quite a few cars and i do not want to get any slower

What year is your car?

gtxsport11

mine is an 06

You do realize espically up north the temp diffrence between your dynos and how big a diffrence that makes right? I also drove the car for a week before dynoing it to allow it to recalibrate the computer to the new amounts of air and fuel it was seeing.

XM15

I didn't dyno it the same day.

gtxsport11

blktrax how do you like it cause we seem to have the same performance mods except i got the dc sports cat back

blktrax

i know i corrected myself

XM15

Easy man, I posted before the page refreshed. Its all good.

BTW, what do you mean when talking about temps up north?

blktrax

Love it, wont run without it. and i can say beyond shodow of doubt, its worth it. I paid $280 out of pocket, plus time and fuel to test this, and to possibly get nothing from it but the parts from CED, and to give them the results.

I'm biased only to myself and how I want my car to perform, I still ****** 2nd and rip the tires (225s to boot) and it pulls hard to the limiter. I like that feeling better than it wheezing out at 5500 and debating to shift.

gtxsport11

blktrax could you tell a difference in the gain?

blktrax

Ambient temprature, your run was in april most likely 50's a lot less humidity ect ect.

That effects Intake Air temps and plays with the computer, and timing. Plus throw in it trying to understand what its seeing with more air and tring to compensate with fuel to keep it from knocking.

Thats why i didnt use my very first dyno runs back in may, I redynoed base lines a week and a half before doing hte test, 7 days before the final, unhooked the batt for a night, drive it to work for a week, hard and not so hard, then took it to the dyno.

gtxsport11

good than it should be the same for my auto then cause mine used to wheeze also so i hope it will hit it good now
i am gonna do the install after i get my ss/sc manifold and ss/sc downpipe put on and the do the intake manifold i will keep you posted on what it does for my car

blktrax

Absolutly. Without a dyno, 20 hp at the top you can feel it. First 3 times i tried a strip launch, i banged the limiter because it was winding up quicker at the top.


You also have to rember that I tested this without the DP and Manifold, I just added those in the last week, and I STILL do like it.

But XM tested this also with a DP and a Mani, so as they say, "You're mileage may vary".

I plan on getting back to the dyno in the next few weeks, funds permiting.

But over all, I still stand behind the swap. I enjoy my car because of it.

gtxsport11

how does your exhaust sound with the stock ss/sc dp and manifold added to it?
does it sound ricey or is it muscle?

how many mpg are you gettin?

blktrax

Its very deep, its never ever made a rice crackle.

33 to 35 if i dont want to hear the exhaust, witch i do..... A LOT...

DIC says 30.2 now. so 29 to 32
