I want to keep this as short as possible. Testing takes time, time takes away from dealing with customers. He does a great job doing more than 90% of vendors out there. If an intercooler has better results with a 10 mph wind fan, then it will have better more dominant results with an 80mph speed. Their testing IS accurate and their stuff is just as good and better than any other stuff out there. End of story.

 

David put it into pretty good perspective I think. How many cars/shops have made it to the 9's with the Nisei?? I cant think of any...personally I cant wait to recieve my deluxe fmic from buschur, hopefully sometime this week..

 

because those shops build their own intercoolers and use them. saying oh why dont the 9 sec evos use nisei does no justice at all. they are not building a shop car here their just offering a really good intercooler for anybody that wants to buy it. dont forget they are the new kids on the block so their not gonna have a 9sec car sporting their intercooler yet.

 

Don't forget there are a SHlT load of people who couldn't give a SHlT less about drag racing... a good heat sink would have a bearing on a 9sec or less run. So in that light, what a intercooler can do in 9 seconds or less is not utterly irrelevant, but less crucial in the grand scheme of things for all of these STREET cars.

What you "I live my life 10 seconds at a time" cronies really should be referring to are the people who have beat on the Buschur intercooler for 20mins or more ("tracking" the car). Robi comes to mind as do a few others. So quite trying to help David out... you're not helping... not that David needs any help.

 

The only downfall of the Nisei is it's best attribute. An intercooler that large is also going to be heavier. And if you're road racing it's weight that's in the wrong place...but I still ove my Nisei. Everything is a trade off.

 

Buschur... actually I called you a long time ago about my intercooler situation.. i tried to get a replacement but you said you couldnt help me...

back on topic.. on the dyno my old white evo we compared the Avo, Pruven and BR fmic and the dyno showed that br made the best power.. as for the other fmics i would not know... the br showed around 14whp gain from stock ....this was done at Pruven Performance around 2 years ago... with my experience BR products show great power gains.. ive ran many low 12 runs and 11.8 with an almost full BR setup a long time ago WITH Stock turbo... the only problems i had was the FITMENT...

 

I have never recieved better customer service then I did with David Buschur, simply the best with his products and his honoring them.

 

There will never be anyone with the time nor money to have so many different intercoolers tested back to back to back (etc.) as the logistics involved in performing such tests and the ever decreasing ability to repeat the conditions required to come to a real-world result to "prove" or "disprove" that one company's intercooler is "better" than anothers will never be present.

I'm not soing to say that any company's intercooler is "better" than another company's, because, in all honesty, I have no personal experience with any of the intercoolers being discussed in this thread, but there are so many different factors to consider for intercooler efficiency and performance that I would be willing to bet that the testing of numerous intercoolers under varying conditions accross a given time span will yield different results concerning which intercooler performed the "best" after each test.

The terms "efficiency" and "performance" are going to mean something different under certain circumstances as well. An intercooler that cools efficiently may very well provide a pressure change that is undesireable, and an intercooler that flows really well might not cool at all because the airflow moves through it too quickly.

And the argument concerning bar and plate vs. tube and fin is almost pointless because there are so many different types of tube and fin "combinations" as well as bar and plate "configurations". Are you comparing extruded to bump, or square to split square, or split square to extruded, or what? And with what external fin design because it isn't always necessarily the same as the internal fin design. You can't generalize these things and think that you can make a point because each one has different charateristics which will vary under different circumstances.

Also, no one seems to have mentioned ANY intercooler's ability to allow for maximum ambient airflow. This is one of the most important factors to consider. If air isn't passing over the face of the core because the external fins are too dense or because a bar and plate core inhibits more airflow than a tube an fin core (another argument entirely), it won't matter how "efficient" the internals of the core are. If the air is passing around the intercooler because it doesn't fill up the grill opening, or if the air has no where to go behind the intercooler, there is no ambient flow, hence no cooling efficiency.

An intercooler that performs well on a "drag strip" might night yield the same results on a "road course" or at an "auto-x" event nor a dyno for that matter.

Unless someone is going to compare every intercooler under every possible condition on a numerous vehicles under varying levels of tune........

.......No one is going to win this argument.

There are too many variables and too many different ideas and theories pointing in different directions with no real evidence that anyone has the "perfect" intercooler for an Evo.

Pick an intercooler that fits within your budget and needs. If that means sticking with stock, there's nothing wrong with that.

 

actually ambient airflow has been mentioned.... maybe not within this thread but in numerous other threads that i and many people in this thread have posted in. it's just becoming quite redundant to repeat all the same info every time. there is enough data out there for everyone to make an intelligent and educated decision. it's all about what the end user wants (needs).

 

For someone who is supporting the "new kid on the block"(Nisei) you sure do sound like you have a personal vendetta against Buschur Racing.

Rollaway, how did your aluminum intercooler rust? I would like to hear the explaination behind this. You mentioned a bracket breaking too. I also had a bracket break on my old Greddy intercooler from taking a bump too hard in the car. The impact snapped the otherwise perfect weld like a toothpick. Just goes to show the best welds aren't bulletproof.

I haven't met any vendors that have as good customer service as Buschur and from what I hear AMS. If something is wrong with a part or something happens to it, Buschur stands 100% behind the products his company makes and sells. AMS from what I've heard is just like Buschur's service and products, first class all the way. I have never dealt with AMS personally yet, but I plan on making a couple purchases through them in the next couple weeks. Both company's are grade A topnotch products and service. I am happy to say both company's products will be in my car very soon.

 

i don't understand the relavance of an intercooler on a 9 second car.... from what i know intercoolers are useless on drag cars... ESPECIALLY 9 seconds at a time. the heat you soak in the staging lanes actually makes those ntercooler kits waranted. the only thing you need out of an intercooler on a drag car is flow volume. so you can not have a restriction in the way of making your hp. that says nothing about cooling. for drag cars the heat is already a necessary loss cause so why do anything but make it flow?

br's intercooler does in fact do more tho, it's good at cooling, it has a significant pressure drop nad it's made in house which means there will be imperfections beyond normal manufacturing standards, mainly aesthetics. but all that is ignorable. it's a fine piece of equiptment.

the nisei is also a fine piece, it's made well, well thought out and does its duty very well. it's cheap to boot. this is the one time where cheap, good are in the same sentence. they have their intercooler pipe coming out within the month... all al pieces. they're developing and offering seemless nad high quality systems for evo owners. they're totally serious and totally dedicated to the highest standards. i can't say enough.

 

My dyno operator used a fan with a 27,000 CFM rating...is that good enough?

 

trinydex sumed it up pretty good, thank you.

 

as far as i am concerned buschur has to be one of the nicest intercollers out there. their quality is impeckable and the price is right where it should be. the nisei intercoller looks very well made but is it too dense? i mean there is a point where the more rows u have the less effective it will be. what annoys me is that this topic will come up every 2 months or so and we will just fight back and forth about it like there is no tomorrow. if u want a quality piece that is a decent price and has no fitment issues, Buschur racing intercooler is the way to go.

 

What annoys me too is the fact tt there are people who are too dense to realise that the Buschur is even denser than the Nisei. This 'disadvantage' of Nisei just keeps popping up every 2 months or so I am in no position to discredit Buschur's FMIC because I have no direct experience with it and many of you are in the exact same position with regards to the Nisei. There's no such thing as the best vendor or the best product. Things change......why are we so intolerant of new vendors/products when they can help to keep the established vendors honest?

With so many testimonies on the Buschur, I tend to believe that it is indeed a quality unit but let's keep our minds open to the possibility that the Nisei might be just as good, if not better. The only way to settle this is to come up with a test that satisfy all parties but that's not going to happen, is it? That said, who's to say that with enough time and equal opportunity, the Nisei won't be able to prove itself against the competition?

I say let the vendors fight amongst themselves to protect their business and we keep out of it. Users will only benefit from more choices so let's not kill off the new guys by our zealotry for our fav vendor.
