6.1 Vortech S/C kit update...

Actually it does matter, same thing goes with a supercharger as a regular engine, more air in = more power out. Boost is a funny thing, it's not the full sign of how much power you make, it's actually air flow that matters the most. Ex. Stock blower kit said to make 5psi on a stock motor (be it srt, mustang, whatever). Set up the gauge shows 5 psi. Now change to a higher flow or ported intake manifold, heads, and exhaust and guess what, you'll be flowing more air and making more power AND you'll show less boost on your gauge because of less backpressure. Actually I guess it depends on where your hook up your boost gauge and where it gets it's reading from, usually somewhere in the vacuum system. On my mustang there was actually a spot on a vacuum tree open that had "B" on it, go figure lol! BUT that's what happened to me, made more power and showed less boost on the gauge by modding with better air flowing parts.

With this Vortech kit and the tuning avail nowadays I might say they have this already worked out so my point might be moot.

 

No, it doesn't. Not in this context. If they want 5 psi and they install it and get 5 psi then the filter size is fine and not a problem. If they install it and can't maintain the target 5 psi due to intake flow restriction then the filter might be a problem.

If you're going to change the physical characteristics of some part of the setup then you might have to make changes elsewhere. In fact, after they set it up to their specs, I'd advise against just putting a larger filter on because you think the supplied one is too small. Unless you are intentionally trying to change how it works. In your example, you changed the boost when you changed the physical characteristics of the intake.

John implied he was worried about the size of the filter. If they can initially get the boost they want then the filter is not a worry for that. If John is worried about the filter getting dirty more quickly because it's smaller then he might have a valid concern. He might have to clean it more frequently.

 

Dave you are correct that if they tune with this size filter it will be alright. I just cant believe from a filter that small they can get the CFM they need. I know for a fact a smaller filter can limit HP. Its all about what the engine needs. If they can get the air from this filter so be it. I just come from the old school where you put as much filtering area as you can. Hell my 66 nova has a K&N 14 inch x 6 inch with the new air filter lid...

 

Eeryone but Rick, Moe and that East Coast legless guy... Rick won't settle for just any blower... he's doing it right and planning it through. I just couldn't pass up this price. Yes, it's self contained now and even has a drain tube so you don't hae to remove the system. Thanks.

 

Ya... Lol! I hear ya on that. He said the only PITA part would possibly be getting to the air filter. Might have to look into turning it. I assume it helps with getting it closer to the incoming air and away from the engine as well. Depending on how they have it set up, I might be able to use the AFE "box" to shield it if they don't come with one. Oh ya... and already looking for tire stock!

 

Sounds like SOMEONE is getting OLD!!! Lol!!!

 

Ok, I couldn't stand it any more. I added a space between "S/C" and "Question" in the title. Sorry if you're searching on "S/CQuestion" to find this thread (too bad).

 

Lol! You makin' fun of my two finger typing...?

 

No. It's just that, for some reason, that one was driving me nuts.

 

Cool. Looks like I'll be getting a three pod pillar then. Kris, what's you guy's price on those and color?

 

I second this request... how about a 'package deal' including gauges?!?!

 

Right, from that standpoint you are right Dave (thanx John), if it's engineered for it it will work with a small filter and give you 5 psi, I didn't mean to imply it wouldn't, but it would be BETTER with a bigger filter, just as higher output blowers get bigger inlets/outlets to produce higher flow. More air in = more power out. I was talking more about boost vs. airflow where airflow is the real measure of power, not boost. Boost is a nice term to use for sales and something that excites people so it's good to call it that but it's relative, it's airflow (cfm) that really matters. Look, I don't claim to be an expert on much of anything, I'm not trying to argue with you, I'm not a brain like you, I only go by my experiences from what I've seen happen to me and to others and I've had plenty of experience with supercharging over the years and the "boost" thing to be exact (I recall one time spending pretty much all day on the phone with a Paxton tech complaining that my boost psi wasn't what it was supposed to be and getting a whole lecture on boost vs. airflow, lol!).

 

Well, generally speaking, yes. But they are not looking for more power. Power is most likely what they started with. The design requirements were probably something like "we think we can safely go with a 25% increase in power". Then they figure that's going to take about 5 psi. and they go from there designing a solution that will produce about 5 psi.

[oops, have to take the kids to little league. Will continue with the rest later. I'm not argueing either. It's worth discussing though)

 

Next question...
They have a standard blow off valve that is I think 1 and 1/2 ". They have a nice looking 2" blue one that they make there. Will a bigger "racing type" valve "mess" with the system any or does it not matter due to it being the exiting for safety reasons? Also, I forgot to ask him where they are located. Usually they are visable in the engine area, but if not i will stick with the stock black one.

 

Hahahaha, I don't know anything about that either (but I stayed in a Holiday Inn last night). The blow off valve should be set at a particular psi. I think it needs to be big enough and can be any size larger after that?

Don't those things pretty much blow every time you go from full throttle to no throttle?

 

The blow off valve is to relieve pressure built up in the intake track, to expel air trapped in the inlet tube between the s/c and the throttle body. That air has come out of the s/c but has nowhere to go once the tb closes (when you take your foot off the gas and the throttle closes) and creates pressure. Bigger is better Drew but I would think with only 5 psi you're fine with the stock one. Heck I'm running 8 on my Mustang currently and don't have one ... well, not installed that is.

 

At 5 PSI a larger blow off valve is not necessary...in fact as Scott said probably not necessary at all.

 

X3!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Kris, are you out there? HELLOizza:

 

Yeah, but will we get that "Whoosh" sound when it does engage? -asking this for Drew, because he's a wannabe "THE SHOW".

 

The only Woosh Momo will hear is the woosh as I pass him like he's standing still...

Actually, I just liked the look of the blue valve over the stock black one. The blue one is a racing one that has vents twice as big.
