This product is just out, available from Rebel Devil Customs...good news, i'd probably buy one, my oem hose is kinked pretty good right now with the bigger tb and steeda intake.



https://rebeldevilpower.com/index.p...ocus-performance-products/product/157512-2012-focus-mst-intake-hose-for-63mm-tb



A question for mike if he sees this: Are the PCV and crankcase tubes still super tight like the original, on the original I could not get them in without cutting slits and using zip ties.
Probably snug, but use a little vaseline or oil on em ;)

Thanks for the Update!!

Thank you for the Update on this New Product; just wish I knew about this sooner. I just purchased a Blue one and hose clamps on the 2 Jan.

I'm in the process of returning the products now( I will probably just keep them as a back up just in case this one got damaged) I placed an order for the new one.

I wanted black before so this will fit right in with my combination. I have a TB Spacer and I'll hopefully don't have to trim anything to get it to fit my combination.

Well, I can't return the Blue one I have, but if anybody is interested in it, PM me. Brand New in box and Free S/H.

The original mst was very difficult to get onto my steeda intake, I wonder if this one will be the same
 
#12 ·
With the larger throttle body the stock tube is getting partially caved in, I may have to trim a bit off one of the ends of the MST but im sure I can make it fit, just might make removing and reinstalling the steeda intake a pita

[drummer] I got mine installed, but I had to do some trimming [ninja] to make it fit. The two little hoses I cut off so they were just little nobs left to fit the factory Hard plastic sensors.

Plus I have a 1" Damond TB Spacer, so I had to trim about 1" off. I could have trimmed a little less but it all worked out. Without further ado[popcorn]

I would say its well worth it [idea] and will add better throttle response and give you a slight advantage [thumb] over someone else who doesn't have it. It will open an almost straight shot to your TB. You won't see it on the dyno, but in the real world you feel the extra punch w/ better throttle response.

It'll take a little while for the computer to learn the extra air flow and adjust the Throttle response. I will say it has quieted my exhaust at idle, but at WOT it will still scream. More to come...

I would disagree on this, not performance you will see on the dyno but it will show up on the track. In real world settings just like adding the ST Snorkel it allows for better air flow to the filter which adds better off the line response.

Just like when you replace the Steel flywheel and add and aluminum it lightens up the unsprang weight which allows for faster RPM's to get to your power band. Adding the larger TB and hose gives the engine more response which does almost the same thing. More response, faster RPM's to reach your power band.

Its all about the combination [hihi] of your set up, one item won't add allot but when you add it all in your combination, that is when you will see power gains. Granted it won't be much 1-5 hp maybe, but what you have and the other guy doesn't gives you the advantage. [headbang]

Focus-philes,

My 2 cents:

The smooth finish is nicer, imo, than the stock accordian-pleated tube and it fits the bigger throttlebody better. It's not a very expensive upgrade.

Tom knows the numbers so I don't disagree that the performance gains are negligible but I put the bigger t/b on to sharpen up the throttle feel and response. It's not an expensive upgrade and it is dead easy to do.

And who can argue with spending <$150 to get some wrench time and some pizzazz under the hood?

Worth the $65

[thumb] Worth the $65 for ease of install, straight shot to the TB and allows way better throttle response.

The Focus has already settled down and when at idle with my exhaust is quieter and smoother sounding. You still hear the burbles on idle but with the radio on you can barley hear them.

I would say it helped to calm it down with the extra air flow. Still screams on WOT...

Oh, it does come with the SS hose clamps that are made for the Silicone hose and have the smooth metal piece to protect it from the gear notches.

I am trying to understand the points here, I guess both you guys are correct (in some sense). When we dyno a car, the dyno gives the power output but do not give information about another entity called "TIME".

I am trying to comprehend the discussion here I could be wrong. Lets take an example of 2 exactly identical cars A and B, only A has a intake hose and large throttle body, vs B is stock, If they are dyno'ed they would give exact same power graphs (may be slightly different because not all cars are same, lets assume they are same hypothetically), but you get the point. This is what 1turbofocus is telling. Both A and B have same peak power numbers at same rpms. (lets assume that is at 5k rpm).

Colossus is telling that the TIME it takes to reach to that power numbers might be different because of the difference in throttle response. Hypothetically if car A has better throttle response because of the intake hose and bigger throttle body, then car A will go to the peak power let say at 5k rpm but it only takes "6sec" and car B will go to the peak power at the same rpm as car A, 5k rpm (cause they are hypothetically identical) but takes "7sec", might have a slight disadvantage on timed race.

The power graph is same but the one car have an advantage over the other, I think same rule applies to other factors such as the weight of the car, if a car is lighter than the other, then the power numbers will not change for both, but the time to reach the peak power will be lower for a lighter car and hence the advantage.

This is what I understood about throttle response, let me know if I am wrong. There is no way to measure the entity called Throttle response, and dyno's couldn't measure time. Is there a way ?

Actually the Dynojet does measure time as well

You cannot have an increase at the track that the dyno doesnt also show , To have better throttle response you have to have an increase in TQ , no increase in TQ you wont go faster on track

The larger TB and Hose doesnt add any HP or TQ so track times wouldnt change

Ok..

I'm not sure why you are hung up on the TB and pipe; below is what I wrote about adding them to your combination.

"Its all about the combination of your set up, one item won't add allot but when you add it all in your combination, that is when you will see power gains. Granted it won't be much 1-5 hp maybe, but what you have and the other guy doesn't gives you the advantage."

We could go round and round on this, TB Spacers, Under drive pulleys, Un-sprung weight etc...

We'll leave it as that [:)] It all comes down to your combination, Reaction, and how well you know how to drive your wheels off. [driving][burnout]

Correct me if I'm wrong, I know you have numbers for dyno tuning and know your stuff. I'm not trying to piss anybody off, but putting my input in. This is what I'm getting at:

Allot of the products won't add horse power; some will. The one's that do, most companies will have dyno's showing the power gains and can back up there claims. This has allot to deal with what kind of set up the test car had upon testing the product.

Others are to reduce weight off the engine to allow it to Rev faster and achieve it's max power band quicker then someone who doesn't have the product. These might not add HP/TQ but they allow for the engine to get its maximum power to the ground.

Your main goal is to stay within the max power band as much as possible so you get the most out of your engine. Using a Tach and Shift light help achieve this for each gear. Tuning helps allot especially when you have an automatic transmission and the shift light might not be able to be used. Steering wheel shifts might be able to still use the shift light.

The other factor is the weather on the day you go to the track. This is one issue I believe can make or break some cars. This is when tuning really helps to give you the best outcome on the race.

Each person needs to do there own research to see if the product is best for them and there project car. There's a plethora of information out there to make the most informed dissension.

There will he further research into gains vs no Gains for the TB, the hose will only get rid of the accordian turbulence. One tuner testing the TB does not verify gains or not, thats like saying if one person built an engine and did his testing, and showed gains, then technically his word would be final, however another person using the same engine but his own tuning, and finds out otherwise, well now you have some data......... we will be testing my Hatch with stock vs larger TB, same day dyno, only difference will be TB and Tune for TB... no other adjustments.

If there are gains, we will post, if no gains we will post, if only tb response gains we will post

Really , " One tuner testing the TB does not verify gains or not " SERIOUSLY so if you get different results your results are no good and if you make a part and dyno it the results are no good unless another dyno backs it up < You just opened your own can of worms , I will remind you of your own words down the road

You sell these parts so it will be no shock to me that you see 1-3 hp gains so you can sell product , I have no skin in the game because I dont sell any TB or the hose but my results are no good because it was only one dyno result and that isnt enough oh and you didnt tune it of course , the testing I did was dyno TB stock no tune , dyno bigger TB no tune so where does tuning come into play , you have stated no tuning is needed for only TB , and this is a TB and hose were talking about not an engine

Wrong, Tom; you have tested the products as you have stated throughout this thread. So in essence you should provide Dyno results for the TB. Plus what if anything else was added prior to the testing, such as anything not stock.

On another Thread you stated there were no gains for Steeda's TB Spacer. Steeda responded and they have proof of gains. They also test all there products for HP/TQ, UDP was another one I remember and there are plenty of business and shops that do prove gains.

Agreed no gains except to eliminate turbulence from accordian hose.. and its prettier, and using this new one allows for better fitment on larger TB
