03whitegsr, Thanks for bringing up some valid points . At this time it would not be the right time to do this. I have many versions on the table for all applications from street, 99% of what is out there, to the 1% 700 plus whp "crew". For me I can not justify it at this time . As David has stated the cost of doing these will be high. To do this properly it takes a lot of time grinding, welding, and flowing the runners and plenum, and each manifold will be done this way no exceptions. This is not your average gasket match and TB mod. I will not get into how or why or an engineering discussion. It has been done on other threads and ends up in flame fests, I will let the results speak for themselves. I wish there is way I could wave my magic wand and make the costs go down, but sadley it comes down to time and materials. Thanks, Indy

 

Wow, you're really on to something there. Let me know how it works out for you.

Maybe when you're done we can do some a/b testing against the Indy-designed stock manifold I'll be running.

 

So does this mean you will be looking at offering variation in the design of each intake manifold based on the person's application? Would this possibly change the cost based on what is specifically asked for?

 

David and I will review the data and choose what we believe to be the best overall combination. My first version seems to be pretty damn good overall for most popular engine combinations. Development will be on going and never ending. To answer your question the cost will remain the same due to the time involved. David will offer one version to start with, and as things progress over time, I will update as necessary. This will not turn into a new manifold every month. Thanks, Indy

 

So whats the pricing then i guess now we wait...

Def. interested though they say you cant do better then oem. Well in most areas i guess. a

 

Keep up the good work guys. It's impressive to see a stock modified manifold perform so well.

 

While the plenum is offset on the stock intake manifold there is nothing in the way, so it seems Mitsubishi built it that way for a reason. I can assure you that Mitsubishi has enough engineers that they can manage building an intake that works. If you take into consideration the goals of Mitsubishi when they built the intake (low/midrange) and then compare it to all the intakes I have tested it's obvious they hit the nail on the head. Now consider that Indy's modifications have kept the best low end and is just 8 whp short of the best top end and it's obvious it's a darn good part.

The runners, BTW, after this work is done are balanced so they flow the same. We were just looking at the intake manifold today at the shop comparing it to a stock one and the amount of work done is amazing. I had to send this first one back along with another stock one for the 2nd try.

I'd like to post pictures...........just can't bring myself to do it

Hope to have version two on my car in within the next two weeks.

 

Cool stuff!

I would have loved to be a fly on the wall inside Indy's head when he first examined the stock mitsi manifold for the first time

 

crcrain, Thanks, I had the concept and design before I bought my core on ebay. I knew the stock Mitsubishi design was good out of the box, it just needed a tweak here and there to make it work better. After talking with David, he confirmed my thoughts, added more, and we went further into the modifications. To be honest I would have been happy where I was going to stop for my street car, but David thought it would be a good idea to go even further. I'm glad I listened, think what you want of Mr. Buschur's personality, but the man knows his stuff period. How many shops bring new components and combinations to the Evo community at the rate he does? mabey a few, one or two max. This is my hobby nothing more, and to have a shop that will dyno and test my parts for my personal car is awesome. He is the one you should thank for bringing them to the public.

 

^ true that..

every week I see a post from him and I'm like "oh damn"

should've waited a bit longer

 

Indy,
What is the big difference between your stock mani vs DB's ported mani? What is it that DB forgot or did not do on his ported mani?
Im sure you cant discuss every dateails but give us a little bit of info. I am about to install BR ported mani.(got it from a friend)
Should I send it back to Buuschur or do you need a fresh/stock one to modify it? Would it cost less coz mine is been ported already?

 

evovin, the only thing that is stock about my manifold the way it looks from the outside...his ported manifold has worked very well and I was going to get one before I did this one...Sorry, but no info will be discussed...you need to contact Buschur Racing...no, the amount of time required is still the same.

 

I was actually looking to have a discussion on the possibility of Indy EVo, somebody that has extensive knowledge and background in racing, designing something more cost effective.

For example, you can pick up a cast Eldebrock intake manifold for a Honda for $350. Once the design is done, I would assume that the price to cast the pieces should be very similar between a completely stock manifold to the ultimate power monster that Indy could create.

Just seems like there is the potential for a manifold that could require substantially less labor, meet the same requirements (stock like fit), and open up additional possibilities, while hitting a lower price point by eliminating costly specialized porting work.

Considering the connections and knowledge he holds, I am sure he could come up with something better and more cost effective then I could. Is that what you want to hear?

But thanks for your comments.

David, as mentioned, the factory seemed to be after maximum midrange matched to the factory turbo and cams. I don't think that's what the average person interested in an aftermarket manifold is after. Just because there is room for it doesn't mean that Mitsubishi's engineers needed to use that room to hit their target goals. That however doesn't mean that it wouldn't be beneficial for what your target market is after.

 

03whitegsr, thanks for the comments . I have met Vic Edelbrock and his oldest daughter a few times and saw what it takes to produce a quality part, for what we are doing the market is very small compared to the Honda market, and thats very small compared to the Chevy market. I think you know where this is going, to produce my manifold I would need roughly 250.000.00 or more for engineering, tooling, prototypes and final production. In reality it is not worth going that route for possibly 100-200 manifolds at best before a major revision happens. The cast manifolds still need hours of prep time before they are anywhere close to be run on a racing engine. I can tell you for this manifold in the racing world it would be 2000.00 or more for the quality level here. This is not a quick gasket match, open the TB area and send it down the road, it is a very high quality professionaly done component, think Rolex quality. This is the only way we can produce the results we have. I will not ***** this out for overseas production it is against everything I stand for, and the day this is copied, it's over. I will NEVER produce another Evo part. I don't need to. 03whitegsr these comments are in no way directed at you, I'm making a statment because I'm tired of all the copied parts being shipped here that do not work, don't last and that sell because they are the cheapest. They are not so cheap after you have a failure that takes out your car or engine think about it.

 

Thanks for the reply. Yeah, I see where you are going with it. It sounds like the price point on this thing is going to be over $1000? I was just imagining that you could cast a piece for a similar price. I've been curious about the Honda numbers vs. the EVOs. Yeah there are a lot more hondas out racing, but there seems to be several different manifolds made to match the different motors where on something like the EVO, a "one-size-fits-most" might be able to get the numbers up high enough to make it worthwhile.

I hate to see somebody like you get turned away from the community if/when your work is copied. The sad part is, it is probably inevitable that somebody is going to start porting manifolds and try to pass them off as your work. Particularly if you are going to make these in a large enough volume for them to start popping up for sell as used pieces. Any chance Buschur is going to do some kind of serial number system that may allow somebody to verify that one of these popping up on the trader is the real deal bad *** IndyEVO intake?

I look forward to seeing the next revision. Great work on what you have done. Sorry, I'm not trying to question your judgment, just interested in the driving motivation behind your methods. That and I want to see some bad *** custom cast manifold for the evo. In my own mind, I think that a cast piece is the best option because of structural rigidity and design configurations that can be cast more effectively then on a fabricated piece. Considering that the flow through the runner is dictated by wave propagation, it just seems to me that the best piece is a piece with a high natural frequency to avoid the possibility of the manifold natural structural frequency affecting engine performance. The casting process also allows better cross sectional runner control then fabricated methods since you can blend different tapers and shapes into curves and other features that is very difficult to reproduce in the fabricated pieces.

Sorry, on with your thread. Again great parts and I can't wait to see what else you come up with.
