C&L Intake Manifold gains 27HP!!!! But there's a catch....

[chopstix]

The fuel will puddle in the intake

when is the last time you saw raw fuel in your intake tract after running nitrous.

this is a 100 shot pull ...the intake has a clear top.

Before you watch the vid ask yourself....will you be able to see the nitrous/fuel mixture.

I just need to put my $.02 in

Both the C&L and JPC are just like going with a Sheet Metal Style Manifold. They are huge, they flow a lot, but they are not practical for a basic bolt on car... or hell even a small power adder car. This is not needed until you're pushing big power with a lot of ait flow going through that motor.

So unless you're planning on making 600+ RWHP, this expensive upgrade is not worth it IMO.

No, but we have the JPC intakes.
Regardless if we have them or not, it's NOT a cost effective modification nor is it needed for a car that is not making high horsepower and/or revving to the moon

in my opinion even if u dont get a lot of power n/a it would defenetly make the job easier for tuners if it could flow better then then the stock intake. as i was talking to my tuner the other day, run a big shot of wet nitrous is calling for trouble because of the simple reason that the intake doesnt seem to flow gasoline really well, and this could cause a piston to go lean while spraying.

if this intake has better flowing capabilities and it could get about the same amount of mixture to each piston it would make the car a lot better and more efficient. meaning it would be really worth it. but lets see what the different experiences would bring to the table.

Intakes don't flow gas, they flow air. Gas is sprayed directly into the cylinder from the fuel line via the injectors. If you do direct port injection with a NOS, it will work fine.

true but for us meth guys who spray pre tb this would help alot ask steve he will tell ya his went lean on a cylinder spraying a big shot through the stock manifold

No, but...




Thank you, drive thru...

That manifold is way different than the curvy EFI manifolds. Just ask 5-liter guys about puddling in the manifold. As for "seeing" it, not at those air speeds but it doesn't mean that it isn't happening.

Back on topic, I can kind of see where BBR_John is headed but you cannot argue with our results and the look factor. There might be other mods to do but this one is certainly effective and looks good doing it.

I have seen both manifolds in action--the JPC in a variety of applications--and they both serve a purpose in the marketplace.

That's fine... if you want to waste your money. Have at it. I'm standing by my statement. it's worthless for a basic bolt on car.

WOW! You pick up peak horsepower above 5500rpm.

BUT LOOK

You lost 20+ hp and TQ below that... where it really matters.

You go for it.

Agreed; $1200 for headers make the $800 C&L an attractive addition... can get both for less that JPC.

C&L has the dynographs from the article up on their website.

Before

After

Just for grins and giggles here is an animation of both graphs together. I didn't feel like taking the top to try and merge the graphs into one image.

Doesn't look like there is any losses at all unless you are looking below 3000rpm, and who races at that speed?

It looks pretty curvy and EFI like to me ( their aren't snail shells in our intakes). As for your air speed comment that is why you don't spray below 3000 that is asking for your shit to backfire.

30rwhp

I'd say thats pretty good.

did you see the graph... tq is higher in upper rpm range... at least from the graphs shown.

+ or - 2ft/lbs not a big deal when can use 300+ for an extra 500+ rpms...

That was with the monoblade TB, but gains are gains IMO. It was 27 with the stock TB.

 

[05yellowgt]

Looking at the after graph, it doesn't look like hp curve had quite peaked yet when the dynograph stopped. Or is it just me?

 

[Dex]

I'll take that for my turbo setup then. Running 13lbs on the street 17 at the track

 

[05yellowgt]

I'm want one so bad for my car but I can't let myself spend money on the car right now. Too many CC bills to get paid off.

 

[chad05gt]

Mine is being installed as i type this (with new FRPP 3V Tbody installed of course). I will have the results for a N/A-Heads,Cam,Long-Tube car with CMCV deletes already installed (will be taken off for the intake of course) results tonight.

This will be (from what I can tell) the first non biased test...

...anxiously awaiting results ... repeat.

What makes me interest is the totally stock graph.

The two lines are almost identical down to 2500 RPM (A little bellow actually), give or take all the way up (translation: about the same torque through out the midrange band) until you hit 4500, which is exactly the same spot where my graph starts to fall off, then the C&L continues to climb to give upwards of an extra 15-17 HP. The stock number of ~276 is strong enough to make me think that the before graph was with a custom tune, so it is apples to apples.
