GO BRUINS!!!!!!!!!!!!!!!!!!!!!!

 

Hey Scott, this guy has a hitch.

same guy,$25. less. offer him $75.

OK what is the website for finding rental property that you guys have used before?

 

VRBO and homeaway. Ive had nothing but good luck with both

 

URD does have dyno pulls with their IMS showing a smoother and more powerful curve.

 

Trulia is a good app for your phone that list rentals. Im sure they have a website also.

Edit: are you talking about vacation rentals?

 

He looked like lassie... Now he has a sweet crew cut look on his ass...

 

Yes, vacation rentals.

 

Moping around the house all depressed now? Poor guy.

 

I concur with Dave.

I are here. Been lurking lately, too busy to really pay attention though.

As far as intake mani spacers, from a volume of air/ velocity effect it's not doing a damn thing. All other things being equal, you are not changing the velocity of air entering the cylinders, nor the volume. You are simply creating a longer path that the air has to travel through the mani to reach the cylinder. Sure, you are adding slightly more volume to the intake tract, but that doesn't mean you're increasing the volume entering the cylinder. The only possible benefit as far as flow I could see is by lengthening the path that a given "slug" of air is traveling, assuming it's all nice and smooth, it you may be helping create a more laminar flow pattern. Engines like laminar flow, it's the reason you polish intake/ exhaust mani's. The better your flow pattern, the more efficiently you deliver the air into the cylinder. But, over a length of an inch or two, not going to make much difference.

Thermodynamically speaking, it may act as a phenolic spacer provided it's made out of the correct material; one which does not readily conduct heat, or conducts it far less readily than the cylinder head/ intake mani materials. In that case it would basically be insulating the mani from the cylinder head, reducing the heat transfer between the two. In turn this keeps the incoming air charge cooler, cooler air is denser containing more O2 per unit of volume. Denser air means more spark advance. That being said, unless you have a bad ass properly vented hood(one that creates a pressure differential between a point at the front of the engine bay and one at the rear of the engine bay outside of the hood), after half an hour or so of driving the intake mani will get heat soaked anyways so any possible gains there are negated.

Intake runners are a different story. They have a very real effect on hp/ tq. Short and simple as possible: When the intake valve opens it sucks in volume of air. When it closes the air that was behind it is still moving foward and slams into the closed valve, stacks up, and then the pressure wave bounces back towards the beginning of the runner. When it reaches the point in the intake tract where all the runners originally split off it hits the mass of incoming air, and bounces back towards the intake valve. Longer runner, the longer amount of time it takes the pressure wave make this round trip, shorter runner the shorter time it takes the wave to make the round trip. In intake runners of the size that will fit into a car/ truck the pressure wave makes this "trip" multiple times. By changing the length of the runner you vary the time at which this pressure wave returns to the intake valve relative to the valves next open cycle. You can time it so that this pressure wave returns during the few degrees in crankshaft rotation when the valve is open. This forces a larger volume of air/fuel mix into the cylinder than normal. More air = more powah. But, a given length will only benefit a narrow rpm range. In general, high RPM, lower torque from shorter runners, lower rpm, higher torque from longer runners (i.e. more top end, or more low end respectively). But, there are a lot of other factors in the equation. In a longer runner the mass of air in the runner also has more momentum, so when the valve starts to close to is able to ram more air into the cylinder compared to the same diameter but shorter runner. But, for the length changes were dealing with here (1-2" it isn't going to make a whole lot of difference there). By changing the runner lengths you're changing when the pressure wave (pulse) returns to the intake valve.

So, in summation, I personally would do not think there is any benefit. I could be wrong, and chances are I butchered some of my attempted technical explanations. But on an EFI engine I don't see any benefit. Changing the intake runners will effect power band. As a side note, i'm not entirely convinced when dyno gains in the few HP range are claimed. There are a LOT of things which effect HP output of a vehicle. Unless you're monitoring them all, and can show me the only thing that has changed is adding the whatever widget is in question, i'm not convinced. Put one on an engine dyno in a controlled lab, and show real gains that are well outside the scatter or standard deviation of a good sample size of baseline runs. Then i'll be convinced. Otherwise, i'll keep my monies.

I can provide equations and some nifty science if need be, but I am tired and watching the bruins and drinking.

 

Go Bruins!!
This needs to come out again

Short notice time share rentals all location's cheap. I've used them several times......Justgottago.com Check it out

 

Thanks, I'm all over it. Trying for an OEM one first...http://hartford.craigslist.org/pts/3706092230.html
...Next on the list.....ended up makin m both an offer......will see

 

Humidity is significantly lower on second run...

 

I think the only time I looked into manifolds was when I had my LS1, I guess a LS6 manifold was a decent upgrade.

 

100% agreed. I was too lazy to explain and I think you explained it in a way everyone can understand. I'm sure both of us could go all technical and only a few will understand. Save the $200 and save for a blower. You are looking for more volume aren't you?

 

Humidity I'd still high. I've seen an 04 cobra gain 30 horse running in the winter with the doors open. Dense air, moe fuel, spark advance big boom, fast and quick rotation

 

Yeah I noticed that and ambient temp is lower too
