I need your guys oppinion on what Alky kit should I buy. I am just comparing AMS kit and Buschur. If anyone can advise what are the differences and which one is better?? (It says AMS kit runs with MAP sensor, I dont know if Buschur does as well??)

 

Buschur Kit

• Much less expensive ($200+ less)
• Progressive controller (includes MAP sensor)
• Easier to install (comes as one assembled unit w/new tank)

AMS Kit

• Much more expensive (over $200 more)
• Progressive controller (MAP sensor is extra charge)
• More complex installation (pump mounts separately from tank, doesn't come preassembled)

I just went through this decision process and was willing to pay the extra $$$ for the AMS kit if I could understand any benefit from it (I wanted the best alky kit I could get since this isn't a good area to be cheap on). I wasn't able to discern any reason for the higher price and it seemed that the Buschur kit was just plain better. What sealed the deal for me was when I called up AMS and asked them point blank why I should get their kit over the Buschur given the large price difference and they couldn't cite one single advantage of their kit over the Buschur kit.

You'll hear some people go on about how great the pump is on the AMS kit and how a Shurflow pump (AMS) is better than a Flojet pump (Buschur). I don't buy it. The Flojet fits the car better and works fine. I've priced both pumps and they are comparably priced units.

With the Buschur kit, you also have a lot more successful users on this board to consult with. There are a handful of AMS kit users on this board getting good results (SeanI, midwestmonster, etc.), but many more using the Buschur kit with good results (evodave, Ted B, Ivan_C, etc.).

I chose the Buschur kit for all of these reasons. The biggest reason that gave me pause was that Julio Don, the owner of alkycontrol -- the company that makes the AMS kit -- is a great guy and extremely helpful for tuning advice online. I almost got the AMS kit for that reason alone, but I just couldn't get past that phone call with AMS and the larger number of successful users of the Buschur kit.

When I was trying to make this decision and asked questions comparing the kits, I got very few answers. Hopefully, you can make your decision a little more easily than I did.

 

good write up /\. I can tell you from experience that the buschur kit is top notch. I havent worked with the AMS yet, but your cant beat the buschur for the price. And yes it has a map sensor built in.

 

Thanks EVO8LTV for great explanation and doing research. I guess I'll go with Buschur kit.
Also what you run in yours and what is the benefit?

 

works alky kit? if it ever comes out?

 

I could not have put it any better myself

Honestly - I am not unbiased as I helped work on the development of the Buschur / SMC kit and helped refine it to the point it is now at. With the newest version there has been much success.

I see the Buschur / SMC as more practical for the average user given its simplistic install becuase it is pre-asembled

However, in a staight race car application or in a very high whp street car the AMS product may be the superior choice given its huge alcohol flow capacity. Also in 2005 applications it may start to make more sense given the more complicated install in those cars due to the lack of factory fmic sprayer tank.

As the writer here stated, I find both the Buschur / SMC and the AMS kit to be excelent quality and great choices no matter which way you go

The main point I would like to make here is that alcohol kits are really working great on Evos and they offer a huge bang for the buck factor.

What ever you do - AVOID at any cost the cheaper low budget el cheapo generic kits many of which dont have a indicator light for spray activity or a adjustable progressive activation

Dont try to save $150 on your alcohol kit to buy one of those low budget el cheapo kits - you are better off not getting one

 

You guys, except for Al (who notes the "el cheapo" models which are out there) are ignoring other kits besides the Buschur and AMS. I too went through some research on these kits and found that there are several advantages to kits NOT sold just for Evos. This is one of those aftermarket parts where you don't need to have it made for an Evo.

I know the Buschur and AMS kits are good and work well...but the pumps are basically from a couple of companies that all the good kits on the market use.

Thus, there is something to be said for coolingmist.com. That kit is NOT el cheapo. In fact you might pay more or less depending on how you build your system. The site is very user friendly in that you can custom design your kit with pump options, controlers, tank sizes, and single or dual nozzles. I really like the dual nozzle setup and this is especially attractive in that the nozzles are on elbows which allow them to spray in line with the air flow down the tube, instead of accross it. This makes a lot of sense and is a very attractive option.

After further research, I found that I preferred the Aquamist kit to the ones from coolingmist.com
Reason being, I liked the cooling fins on the pump (promoting longevity), the careful design of the nozzle giving superior atomization (wish it were in line with the air flow, but that may be able to be engineered in later to some extent) and, most importantly, the electronic features that give two separate fail safes. The Aquamist 2s kit has a flow meter in the water/alky line which measures flow and can be wired into an EMS for automatic boost cut should the flow stop for any reason. Also there is a tank level which can warn of low fluid supply.

Personally, I think I'd rather have the Aquamist systems failsafes and spend the extra money....but the Aquamist kit is serious dough (like $1,000). You can save a few hundred by going with coolingmist, but you're still going to spend about as much as on a Buschur kit.

For anyone considering a water injection, alcohol injection, or water/alky injection system...it will be worth a few minutes to educate yourself and look around. At least visit the site for coolingmist.com and the one for Aquamist. You'll see the designs and read about pumps etc. Then you may see there are more quality options other than just AMS or Buschur.

I feel bad posting this ....cause I think David and Eric are great guys making great products...but c'mon, water injection is all over the aftermarket tuning world and there's a lot out there that's good stuff.

Here's a write-up of the coolingmist kit including install on a DSM:

And here's the Aquamist kit (their top of the line...there are some for less)

http://www.aquamist.co.uk/cp/sys2/sys2a.html

 

Aquamist stuff looks high quality, but it's very expensive and (correct me if I'm wrong) not as reliable with straight methanol as the AMS and Buschur kits. It also appears to be very complex to install and wire. When Works gets their act together, it may be a more viable option for someone without that technical expertise, but I have no doubt that it will be very very expensive. I wouldn't want a kit that cost too much because that sort of defeats the advantage of the mod, unless you have everything else already.

With Coolingmist, I just can't get comfortable with the plastic-like tubing combined with barb fittings. That really does seem like a "cheapo" approach compared to using braided lines and fittings.

Also, where are you getting your information that it's better to spray in the direction of the airflow using an elbow? That elbow is going to block the tube more and if you can get adequate atomization with spraying across the tube, then that would seem like a better approach. I think that SMC used to have the elbow approach and then abandoned it for these reasons.

I agree it pays to do homework on these kits and look around at the options. I did just that and checked out Coolingmist, Aquamist, the T6P forums, the turbobuick forums, NASIOC, etc., and settled on the Buschur kit.

 

Well, you've got some good points. I don't have any data that shows that the elbow nozzle is a more effective design...that's just intuitive, but maybe with adequate air flow and good atomization, you don't need it. But as far as the cross-sectional area of the nozzle blocking air flow...c'mon, that's ridiculous; are you running 1/2" piping? That small of an object in the intake pipe isn't going to do much but create a small amount of turbulence, which would also help with air/meth or air/water mixing. But, true, it may be unnecessary if there is adequate atomization from the other nozzles spraying at a 90 degree angle to the pipe. Also, I plan to run straight H20 so that's my perspective and I didn't know that Aquamist's system is not reliable with alcohol or alcohol/water mix. Where did you get that information?
Looks like you're a Buschur fan through and through (stage 4) and he builds great stuff...but I think limiting to two options is kind of ....well....limited.

The coolingmist kit uses stainless, braided lines with stainless fittings which I priced out with the owner. There may be some versions which use plastic with barbs (I don't like that either) but I agree with you on not wanting the plastic tubes with barbs...I'd only go with high-quality fittings . Reliability is so important with these systems.

Something I don't know anything about: Does the Buschur system have failsafes?? If so what kind? Thanks

 

nm, I found the thread I was thinking of aqua tune... lol
