C&L Plenum, worth it?

fakefvc · Feb 20, 2004

just read the article in MM&FF, where they did an install of the plenum on a basically stock 02 GT. They saw gains of about 10hp. Anybody think it's worth 189.00 on a stock GT?

Beau · Feb 20, 2004

as a standalone mod i think it is debateable...but if you plan on adding more components, like throttle bodies, MAF's, superchargers, etc, then its worth it.

They saw 10hp at the wheels with a plenum? Sounds fishy.

I thought it had the accufab TB too that saw those gains. I was going to ask this same thing but after I saw the thread stating that everybody's first mod should be springs , I changed my mind.

They did a dyno with just the C&L, then a dyno with the C&L and the TB.

I saw a article showing that the C&L wasn't as good as the Accufab ..
Accufab is $229 tho!
Both had a 70mm TB and the stang was STOCK with a Paper filter!
the C&L combo pulled 254 RWHP
the Accufab combo pulled 264 RWHP
as soon as I get Home I can post the link to the compairsion unless someone here has it..

254hp at the wheels with only a plenum? C'mon...

With a TB I said along with the Plenum

XtorT'r · Feb 20, 2004

that still sounds a bit fishy. I want one but I don't expect gains like that. I stock I have 232hp... going up to 250+ with only a plenum and tb sounds like bs. From what I understand 232 bone stock is on the upper end of what you see before mods. thats over a 20hp boost from plenum and tb, BS.

I just installed the C&L plenum and 75mm BBK on my 2000 gt. You can feel
a difference when you get up past 3000rpm's. I am going to have the car
dynoed and tuned shortly. I'll let you know what my gains are from before
the install. Before install 231hp, 262 lb/ft. Not bad for a slushbox! Thanx
for the info on the Transgo shift kit.

I've read that the C&L plenum has the best gains with a 75mm TB, not a 70mm TB. This information is on the C&L website. C&L Performance

i've read the exact same thing and it makes sense.

StangJonGT · Feb 20, 2004

Even with the TB that sounds high. I just don't believe in a 25-35hp gain from a plenum and TB. What were the base dyno results?

Jon

XtorT'r · Feb 20, 2004

Is there a link that shows dyno comparisons? I want to see that, I will purchase what ever is best.

hognutz · Feb 20, 2004

it is probably the test over at the modular depot. I posted the link in the other plenum threads. he has some mods. he has full exhaust and pullies.

7-10hp can be obtained by plemum tb swap. it has been done over and over. yes it is is worth it for our cars. most poeple spend 150-200 on some crappy cai that gets 0-2hp.

I plan on cams so for me it is a no brainer. to me this is a must do. more so that pullies, cai, crap like that. this will at least help you with other mods down the road.

so short story long this is no "ripoff" it is as proven as anything else out there.

03Sleeper · Feb 20, 2004

Heres what I was shown
I can't find the infothat went with it but what it dose show is the
256.09 "Stock" vs the 264.61 "Accufab"
The info said if I remember was stock 4.6 2004 Mustang with paper filter and
BBK X-pipe "Ya I was wrong about BONE stock but it's good info"
Hope this helps
Dyno
Maybe
True I can Only HOPE!!

yeah that was the modular depot comarison. the stock means "stock" plenum and tb. not the car.

Still there was a 9.6 HPdiffrence between the Accufab and the C&L
So that show follow threw on just about most cars?
the thing I'm getting at is the Accufab is better Even if it's 2Hp more on a stock engine it (A) looks better (B) has more HP then the C&L combo
(C) it costs more...

Jizzeff · Feb 20, 2004

I just bought the Accufab Plenum and a Mac 70mm TB.
337 out the door.

I figured I spent the money on a T/A and pullies for about the same results as this seems to add, from all the research I've done.

If I can get another tenth out of it I will be happy.

Time will tell in the spring I will find out if I wasted my money.
