Cool *NEW* 2.5" turbo intake ***** kit - 02-16-2015, 06:25 PM

**Updated Nov 10, 2015**

all pricing dynos, pics, flow testing, and info can be found here:

http://mmp-e.com/products/bmw-twin-t...-335is-135i-1m

you can also purchase there on my store.

lowest price, biggest inlets on the market, and highest dyno proven results on stock turbos!

Purchased and patiently awaiting delivery. I have Hexon Racing upgraded snails, working with Wedge/BQ tuning, FBO, meth and custom intake mani. This should all equal to some big POWAAA! Will keep everyone up to date!

Looking forward to this kit. Stock fbo +e50 dyno numbers on Wednesday and after dyno when I lntakes are installed to show what intakes will do .

I'm down for the Full Kit.

Looks very promising, great option to the $1.5k kit
Have dealt with the seller in other forums. Very honest and helpful guy.

Car: Anything with a Turbo
Default 02-16-2015, 06:54 PM

Unfortunately just going to bigger tubes is not going to net you anything on stock frames, 2" tubes are good for 40.36 Lb/Min or roughly 585 CFM EACH before the airflow approaches .40 mach, and becomes turbulent quickly. Here is a little copy and paste of a very good article. Basically 2" tubes are good for 680-700WHP before getting to .40 mach. So going any bigger is not required, and will actually decrease performance as its going to slow the air down. Looks well built though.

"*.4 Mach is the point at which air becomes turbulent and losses in efficiency start to occur exponentially. The key is to stay under that speed. You want to use the smallest piping possible that still flows enough to meet your needs. Larger than necessary piping increases lag time with no measurable gain

The velocities are in miles per hour and mach, and the flow rates are in cfm. Measurements for the piping are in inches.


2" piping
1.57 x 2 = 3.14 sq in
300 cfm = 156 mph = 0.20 mach
400 cfm = 208 mph = 0.27 mach
500 cfm = 261 mph = 0.34 mach
585 cfm max = 304 mph = 0.40 mach


2.25" piping
3.9740625 sq in = 1.98703125 x 2
300 cfm = 123 mph = 0.16 mach
400 cfm = 164 mph = 0.21 mach
500 cfm = 205 mph = 0.26 mach
600 cfm = 247 mph = 0.32 mach
700 cfm = 288 mph = 0.37 mach
740 cfm max = 304 mph = 0.40 mach


2.5" piping
4.90625 sq in = 2.453125 x 2
300 cfm = 100 mph = 0.13 mach
400 cfm = 133 mph = 0.17 mach
500 cfm = 166 mph = 0.21 mach
600 cfm = 200 mph = 0.26 mach
700 cfm = 233 mph = 0.30 mach
800 cfm = 266 mph = 0.34 mach
900 cfm = 300 mph = 0.39 mach
913 cfm max = 304 mph = 0.40 mach"

Well I can surely bet that it will provide better numbers than the Vargas kit. We will soon see the results...stay tuned!

Hahaha Tony the troll!!!

Tony, cool story Bro . So much fail in your post its hilarious! Can you hear your market share on intake ***** shrinking?

.4 Mach is a rule of thumb (gross estimate) for maximum possible flow without going to turbulent flow when pressure losses get exponential! BUT it doesn't matter if below .4 Mach , smaller pipe is more pressure loss and less flow period, it is just fluid dynamics and physics, something you have shown to know little to nothing about in other threads I have argued with you, all you have is rule of thumbs using them out of context . Also, the ***** and website you quoted is dealing with the charge side, NOT the intake side so you are using out of context and completely WRONG! On the charge side you have to weigh benefits of bigger pipe against turbo lag due to bigger charge volume, that is where these guidelines help make good piping decisions, NOT on the intake side. nice try bro! And you are right about one thing, air does go slower in larger *****, good call bro! But you have no idea once again what you are talking about because if you knew anything about fluid dynamics for inlets of turbos, you would realize this is highly desirable because when air slows down in larger ***** or chambers it INCREASES pressure because of this little fluid dynamic LAW called Bernoulli's law which I doubt you know anything about. if what you said was even closely remote to true, you should call up formula one race teams with 500 engineers on staff for a couple cars and tell them "your doing it all wrong, your not following the rule of thumb!" LOL!!! Exhibit A, current turbo formula 1 intake below

Also Tony, so much fail in this statement! That guideline ONLY applies to the charge side of a turbo, NOT the intake side. You are completely wrong in applying this to the intake side. I will just chalk this up to you being ignorant and spreading miss information around. Just read the forum posts you linked to LOL, they are discussing the charge side, not the intake side! If this were true for intake side, then why would people ever run velocity stack filters right at the turbo inlet, duh! I hope no one falls for your crap, just blatant miss information.

brb, turbulence is governed by mach #.
but who was Reynolds #?

Bump for my updated response in post #9 to Tony the Troll

Sorry but I've just had it with the guy and what he says all over the forums.

Forgot to mention. This kit is designed to work with any hybrid twin turbos. Only need to change a couple elbows and good to go. Just let me know if you have a different turbo inlet like on VTT stage 2+, no problem. Price is the same.

A lot of pieces in the full kit, see post 1 above. As far as aluminum and silicone, 3 custom aluminum ***** and and 3 silicone elbows (90 and 45 deg)

Are you aware that your stock diverter valves are open at idle and very low load?
You really should put little air filters on them.

Yes but are you aware they are blowing air out all the time they are open because of flow from Turbos and closed throttle valve? Filters not required my friend

However, my new TFT a charge pipe arrives tomorrow and I ill be running 50mm tial style BOV

Hummm.
so why is it so important when you have a BOV to keep it closed at idle/low load?
Even on my turbosmart diverter valves installation guide, they claim to modify the spring pressure when running them VTA, to keep them closed ?

At idle/low load, there is no boost pressure, and the throttle is never completely closed, even at idle.

It's best, but put your hand up to it or piece of paper and you will see for yourself, it's blowing out.

No idea. Never seen a RHD in person or what the space down there looks like. If you sent me detailed pics to the email in original post we could discuss.

that make sense.

your stock turbos seems to love those inlets: much less boost correction duty cycle, 19 psi @6000 rpm (17 previously), impressive ...
