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

[chad05gt]

Called it a night tonight. Going to re-dyno and re-tune again tomorrow.

... makin' me nervous...

 

[matt texass]

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.

Run dry.

Are you talking about me or the MM&FF test car?

You make a crap load of power but I was talking about the MM&FF car.

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.

no shit. im talking about wet shots which is what most ppl use, how many direct port s197s have u seen ?

a dry shot and bigger injectors would be the answer, but again what most ppl use are wet kits.

We tested the intake back in January in Pennsylvania. The air is dry, cold, and corrected altitude is usually at or below sea-level. While there are correction factors in chassis dyno software, they can only correct so much and in my experience in the extreme hot and extreme cold there are different results with the same car. The fact is, the car was done in A-B comparison with similar weather conditions.

You sir need.

Intake looks great,I look forward to more results

Direct port nitrous which this intake provides
the bosses for,introduces both fuel and nitrous.

Im not being a dick here...but how are you
going to introduce all the extra fuel required
through the injectors? you mentioned a 175
dry shot in your other thread,how about fuel.
What size injectors are you talking,how can
they supply the demand for a dry 175 shot?

If theres somthing I dont know,please share.
There was the Nos Noszles back in the day..

It'd be nice to see what heads, cams and this manifold would gain if installed together.

Viper?

Ah cool! Just call me Ricky Bobby... LOL

I was being a smart ass...

Does this look familiar?

 

[matt texass]

Viper?

Correct.

that looks awesome

 

[Mike Galimi]

That wet setup should have no problems since it is a straight shot right to the intake ports. I think BamaChips is running that setup.

 

[NastyStang113]

that looks awesome

I bet it does more than look !!

still waiting...

What you are talking about here is "distribution". Fuel injected intake manifolds were designed for "dry" flow only. Meaning they were designed to move air not an air/fuel mixture. There are some intakes that will have distribution issues above certain amounts of nitrous. This is not much of a concern when you are talking about nitrous shots up to 150 HP. Its also not really that the cylinder is going lean because the fuel isn't getting there as much as some cylinders will be ingesting more nitrous/air/fuel than the others. . A .062 jet on a V8 engine will produce approx 150hp if the mixture is spread across all 8 cylinders, but will make 1200hp if it all goes in a single cylinder.

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.

Yep, EFI intakes were designed to flow air through them. The nitrous part of the shot flows easily around the bends and curves. Fuel is heavier and tends to crash into the walls of the manifold. When that happens, the mix of nitrous and fuel is no longer the same ratio as it was when it exited the nozzle. The mixture of the two is called atomization. The nitrous will arrive sooner to the cylinder, ahead of the fuel, and that will cause all sorts of problems from lean backfires to roasted engine parts thanks to the super-lean condition. Remember, fuel is needed in the combustion process and with all of the extra oxygen delivered by the nitrous it needs the extra fuel.

The fuel crashing into the intake walls also tends to screw up distribution between the cylinders, so even if the fuel made it there with the nitrous odds are the mixture of fuel/nitrous is incorrect. The fuel will puddle in the intake as well as it looses velocity from its hard trip.

Usually, most EFI manifolds can handle a small volume of fuel to go along with nitrous. Most of the time, about a 150 shot from a single nozzle can make it through the runners safely and cleanly. I have seen more and I have seen less.

5.0-liter engines have been known to take more whereas Two-Valve modular intakes are less. I have played with 250hp two-stage nitrous kit on my 1990 LX without any problems.

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.

I don't understand your comment. We just saw a bolt on car gain 27whp for $800. That's pretty decent in my eyes.

I disagree. With heads and cams (which aren't far out of reach for the average builder and I'm sure will be becoming more common) it's showing promise of 10-15whp. For an NA guy trying to get every last bit of power out of it, yes, that's very much worth it.
