The Buschur FMIC is heavier than stock but what they don't tell you is you can 86 the whole IC spray system. I do 20 minute track sessions flogging my car and the up pipe is cool when I check it. The tank full of H2O is about 39lbs...so using Buschurs FMIC makes your frontend lighter...:-).

 

39 lbs? doesn't water weight approx 5 lbs per gallon?

Wouldn't this mean that the tank of IC spray holds 8 gallons?

And also, for there to be a legitimate comparison, wouldn't you have to check the up pipe using the STOCK fmic without the intercooler spray?

 

It's 2.1 lbs per quart and the bottle is 7 quarts.... so I got a little excited :-0... more like 16 lbs ... if I remember, I'll fill it again and weigh it in the AM...

 

Water weighs 8 pounds per gallon.

The FMIC sprayer holds 4.8 quarts -- 1.2 gallons. Source: http://www.evomoto.com/tech_info.php?techID=5

So the FMIC sprayer holds 9.6 pounds of water.

If you were to totally remove the FMIC sprayer and all associated hardware from the car, I doubt it would add up to 39 pounds -- has anyone done this and weighed the hardware?

 

Just weighed it 13 lbs (damn it felt heavier when it smashed my hand against the ground...) I stand corrected... but I still think the BR FMIC - the H2O tank is still lighter than the stock setup... Also the car spools faster after the BR FMIC and piping. Before I installed the BR setup I had two boost controllers and the turbo out put port showed 19.5 while the one I had @ the Manifold showed 17.1 (at the end where the fuel pressure regulator is) sooo.. stock pressure drop is about 2.4 lbs I installed the Kit and the second gauge read 20.9 and I hit fuel cut on the pisswater they sell us here in calif. (No more port for the first gauge in the BR kit) I had to turn my MBC down because this system flowed so freely.

 

wee whoo so i was right about the design being quicker for spoolup......anyway wheres david on this ?

 

yes david does have pictures of his intercooler on the net and the website but he does not ever show teh back of it, because that is his most important part.......

 

buschur didnt design this style....its just not as common...ive seen the backdoor style endtank used in turbo hondas for years...david is just smart enough to use this fmic style

 

None of the picturs show the pipe comming out of the side of the end tank.....where the hell else could it come out other than the back? Come on, it isn't like it was a secret or something!

Give me a break!

PS: No PM's from Dave asking to take it down so I am pretty sure he don't give two ****s.

 

I don't care that the pictures are up there, maybe it will sell more of them and we can be even more behind in welding!haha

They must be working we cannot keep up with the orders for the kits. I think since we released our FMIC kit we have sold about 75 kits to date. Not to bad.

As for the rear exit on the tank you are right it is the only logical way to do it. The very first FMIC kit I built was for my 1991 Eagle Talon. I did both the inlet and outlet like this, it is still the design we use for that car today. In the DSM our kit runs directly past the ends of the radiator making the plumbing as short as it can possibly get. This design has been copied by quite a few other DSM shops now.

The EVO was a tougher job than the DSM as the stock routing while it is long isn't that terrible. There was a ton of room to run the plumbing in the factory area. Problem was there were already 2-3 shops doing just that. We wanted to do it different and what we thought was also better. Doing the plumbing the way we did eliminated quite a few bends and about 18" of plumbing.

We did not do any pressure drop readings on the core although if you go to our site you can find the size of the core, pressure drop and HP ratings.

Glad you guys like it. We left our i/c sprayer but that and some other useless things will be coming off the car as soon as we finish testing the new turbo kits.

It is going to get interesting soon.

So how much was stock and how much was Buschur ??

 

yea and is spool up better?

 

Who am I to question one of the oldest and most repected DSM tuners, but I don't really like the design of the 'backdoor' entry end tank.

Does the endtank have an internal deflecter for the incoming air? If not, how can this design be efficient if the charge has to do a hard 90* bend? I would think it could actually increase backpressure as air 'slams' into the inside face of the endtank.

But WTF do I know?

 

Spools same as stock with zero heat soak.. I hadn't used my sprayer since install so i took it out Had to turn my MBC down (gained 2 psi) to avoid fuel cut.... if something works ... I think having the only complete turbo to intake plenum system pays many benifits that the tank intake doesn't erase.

 

i can c what your saying but i think the gains from the loss in piping are worth a lil turbulance...and if u want u can make a lil deflector so guide air into the turn a lil better....the pipe comes out of the end tank about 12 inches from the turbo....its a direct shot....opposed to goin out the side of the endtank then going around then making its way to the turbo....atleast a foot of 2.5 inch plumbing is saved...thats enough of a drop in pressure to be noticed

ps. david i dunno if i offended u by sayin that u didnt design the backdoor style endtank....ive just seen it around for so long maybe the people copying are oldschool and got it back when buschur was still a garage affair
