Ok first question. I want to get a clear lid, which means only MTI and TSP. I was under the impression that all of the lids will give you about the same power gain, and still pretty much am, just wanted peoples opinion on that. MTI has a GM performance tech article or something linked off their intake page that compared 7 lids to each other. These are their dyno results for the parties I'm interested in.

Stock Car 320 hp 333 tq
MTI 325 hp 336 tq
TSP 332 hp 341 tq

So according them, there is a performance difference between the two. So my questions, does anyone have anything to prove power increases with either of these brands? Does anyone have comments about how well they fit, ease of install, etc?
I would probably just get a TSP one but right now MTI has a deal for clear lids at $99, which is $30 cheaper than the TSP. That is why I'm considering the MTI one now.

And my Fernco question. According to JRP (thank you) and his Newbie mod guide thing, it says you can pick up the Fernco at Home Depot or Lowes.

So I need a 3 inch by 3 inch peice of tubing, in the plumbing depertment? What are these things actually referred to as? Piping, fixture, etc. so I don't have to search all the place and can just look at a section.

Thanks guys.

I think its a pipe coupler. Also u will need to put it in the microwave to get it to fit. I thought i got the wrong thing at first.

So do you need to put it in the microwave so that it will expand? Or just so it's soft enough that you can cut into the plastic?

To make it expand and flexible so u wont crack the lid. I have a mti clear lid and its very easy to crack.

I thought the Fernco replaced the accordian looking tube going from the Throttle Body to the MAF? So why would it matter if it fit on the MTI lid?
And you can still do the fernco mod without having a aftermarket lid, correct?

The air bellow can be replaced without replacing anything else, correct. It connects the TB and the MAF. I would recommend against Fernco (drainpipe) because it is so stiff it sometimes breaks your air lid (which is just on the other side of the MAF). Saving $20 on the air bellow won't feel to great when it breaks your $120 air lid. I would go to www.airflowonline.com for an air bellow. They are $14 and flexible (funny, they look exactly like what SLP sells for $50).

As for the lid, I've seen a few studies that say one is better than another. The problem dynos arn't that accurate. A difference of 5 hp could just mean your car is a little warmer. What they need to measure is CFM, which to my knowledge no one has. Just looking at the designs, I would imagine that DirectFlo and TSP are the best ones, but I would be suprised if they would have any measurable HP advantage to the others. TSP also offers an 85mm version.

Thanks for the website, if I end up getting one I'll probably get one from there. I was worried about the stiffness of the fernco one breaking something since it won't move at all.

i have the TSP lid with a fernco bellow. make sure you stick that sucker in the microwave for a min. when you go to home depot just say your looking for the fernco's i went with my friend who is a plumber to help me find it. =P then ask for the 3" 3"

I have an MTI clear lid with an AirFlow bellows..................


And no problems with engine flex (cracked lids)

If you do get the fernco dont leave it in the microwave too long it will melt . Had that problem too.

I think ill pick up one of those for 15 it will make it much less stressfull when i clean my filter which i do ofter. I wont have to worry about breaking my lid ever time. thanks for the site.

get rid of that K&N filter and you will gain power and save on cleaning..

Gain power by switching to another air filter? The only ones I've even heard of other than that are the Holley Powershot ones.

Oh yeah, so I am right in that it needs to be a 3 by 3 peice of connector right, because I went out and measured my MAF and throttle body connections and it looks bigger than that, around 3.5 inches to 4.

psychocabbage

the fernco I dont see gaining you any real power.. not anything that should be noticeable.

On the dyno (RSI) I was able to prove on two different occasions that the K&N (and cotton gause filters), the Amsoil (Foam filter media) and no filter lost 3rwhp on the dyno repeatedly...

The standard paper filter makes the most power hands down..

Ok, took the accordian type thing off the car so I could measure the connections. Where it connects to the MAF there is a diameter of 3.5 inches. Where it connects to the Throttle Body there is a diameter of 4 inches. So since that's the case, how is it that a 3 by 3 peice supposed to fit onto this?

Tiger2o69

iTrader: (16)

Your saying the k&n, amsoil, and no filter at all , lost 3rwhp compared to the paper filter?

I have heard that the oil from the k&n messes up the maf. I like the way it looks in my clear lid and 3hp wont gain me a tenth. I suppose that defeats the everybit helps but oh well.

This black rubber "bellows" adapter connects a 4" air pipe to a 3.5" air pipe.
Very similar to a hose used in some Chevy Camaro and Corvette applications.
Overall length 5".

Is this what I need? It has the same size fitments that I measured, but what I'd like to know is why my MAF and Throttle Body have different diameters than what people on here say to get sizewise for a smooth bellows?

makes no sense to say a paper filter will flow better then no filter............

yes, the 3' - 3' is what your looking for, i was confused at first and it might be sort of tought to get on the first time, just make sure to use the microwave to make it more plausable, and dont burn your fingers. that rubber gets firggin hot!
