Hey guys,

Good news. finished the last $50 mod: Silicone Elbow upgrade. I wanted to to the silicone elbow mod for some time now. Many of the E36 owners and tuners have started to do this and actually picked up dyno gains (Mpact motorsport and also Samco both make E36 elbow). They claim anywhere from 3-8HP gains depending on mods & etc. I figured it was about time somebody did it for the E30 so I decided to be the first to give it a try.

As you can see i totally eliminated the rubber elbow along wiht some of the other stock stuff. I also relocated the icv to the backside of the intake manifold and bent the bracket alittle to do so. I then used 5/8ths rubber "heater hosing" which can be found at any autozone, it retrospect i probably should have gotten 7/8 so it would't have to stretch as much on the ICV ports but either way its reinforced so its fine. I realized that by just making the crank case vent a open air one that i could eliminated the need for the crankcase vent hose to the stock throttle body before the flap. This allowed me to run the ICV directly before and after the throttle body flat for a very nice OEM solution.

What this does is allow ALL the air entering the engine to be fully metered by the air sensor (which would probably theoretically reduce a lean condition if you had one). It also is a smooth transistion instead of the stock ribbed one. Also the stock rubber ones get brittle and crack so if you need to replace your stock one might as well get a silicone one that will never go bad.

The crank case vent hose was just twisted to run in a U-shape instead of S-shape and I just ran it out the exhaust side engine on the opposite side of the intake manifold bracket.

Overall performance, the idle is excellent and no hiccups/ hesitation whatsoever and it actually feels alightly better than stock. The power levels are slightly better and powerband is slightly smoother but nothing rediculous by any means. I will also note that my coolant gauge was running dead center during the short run i did in the canyons after the install and usually its slightly over to 3/4 so this may have solved the lean contiditon i was having.

Conclusion: Overall I am very hapy with the mod, it can be done for under $50 and roughly 1 hour of labor. For materials you will need 5/8th hosing (comes in like 5 foot lengths), air breather, brass adapter vaccum fittings, and some small o-clamps if you dont have any already. I definitely recommend for a nice little mod. Most importantly of all, this allows me to easily upgrade from 2.75 to a 2.75-3.0" HFM reducer once up upgrade to the E36 HFM. Anyways enjoy the pics.

I'm sure you got at least 8hp by changing the material the intake pipe is made out of!

[Budget Beater]

naw i dont believe it, just saying what Mpact motorsport claims. I would say 1-2HP tops. its equivalent maybe to a fan delete, u feel alittle difference but its not measurable on a dyno or anything.

[PeaveyBassist]

You think you can feel 1-2hp?

[Budget Beater]

well u can feel a fan delete on a E36 and it doesn't show up on a dyno but u can definitely feel a difference, so i'd say yes

[PeaveyBassist]

right...

his butt dyno is accurate.

Motion to change thread titlte to Project Placebo or Project Butt Dyno.

[PeaveyBassist]

Budget Beatoff? Project Butt Dyno sounds good though.

Anyone with some legitimate comments lol, i didn't realize R3V had stooped to 3rd grade insults. Leave the name. Once I get my other parts ready I will start doing more dynos and etc.

[s0urce]

Anyone with some legitimate comments lol,

Yes: Buy a Vowel. You and your project suck at life.

Its a bmw board...what do you want?

How are you financially independant? And if you are why do you live in the projects?

Oh yeah and give me a damn break on the silicone elbow. You are just throwing shit at the wall aren't you? Is anything sticking at all?????
