Regarding the small 1" pipes, that's actually brilliant because if he needs to make a complex bend with one of the pipes on the merge back to the 2.5/3" charge pipe, he can do that much easier than he could with a large box tube. I had honestly thought about the intercooler idea, as the Bell Intercooler site you linked me to had touted "over 3,500 core shapes in stock"...

My only concern is airflow. Intercoolers work great when air can move across the vanes at a high rate of speed. But, if the air is forced to flow in a linear fashion, with one side flush against the car.... ???

Still, this is a much simpler design, as we can now route the charge pipe directly up into the engine bay, as opposed to "through the core, into intercooler, back through the core"...

This is progressing well.

Let me know when he needs the deposit.
Corky also really liked the idea but as an engineer wants to study it some more. I am excited that a BEGi sytem might include an idea of mne! What makes Corky like it is some testing he did on his Miata kits. Like I said earlier. His single round charge pipe leaves the turbo passes through the wheel well then down and into the intercooler. He measured a 30 degree drop just on this 40" pipe before entering the intercooler. Now if you look at the leangth of the charge pipe and if you could route this through 3-5 small pipes, you will basically have a charge pipe that has an intercooler effect. I really like this idea because like you said, we can enter and exit on the same side of the radiator which also was driving up the cost of the intercooler. Another advantage is you will not have a intercooler blocking the cooling air to the radiator. A big advantage for me only is that I will still have room for my pusher fan that is mandatory on a V8. Not only would we eliminate the traditional intercooler but all the brackets and mounting hardware. This would make the install much easier too! Just route the pipe up from underneath in front of the condensor, keep it tight to the passenger side and into the engine compartment then follow the contoured relief on the side of the E320 engine cover.

Looks like we are up to three. Anyone else in on this? Maybe someon knows how to make a list?

Another benefit of no FMIC: no need to carve on the core support and neck down the charge pipe to fit. If you recall, on the Needswings, you have to squish a rubber tube through the passenger side. More couplings = more areas for boost to leak. Using a metal pipe would require you to widen the opening.

I'm curious about the self contained lub system. I'm gessing 2 pumps are required, scavenge and pressure. A heatsink rad in the return line. A tubular aluminium reservoir with window or dipstick and breather.

Perhaps, as a means to keep the kit affordable, we could have the option to opt for an engine lubricated circuit with scavenge pump to return the oil to the motor(left valve cover). In this case, adding an oil cooler to the engine makes sense.

I believe the squished pipe is actaully on the NW DCAI on the drivers side. On my car I had to remove the plastic inserts that the stock tubes connect to in order to run V8 tubes. The passenger side fit very good but the drivers side was smaller and a pain to get the tube in. the NW intake is pretty big since it only sees suction but the charge pipe for our kit only needs to be about 2.5" in diameter. It does need to neck up to the size of the Throttle body at some point. I don't know what Corky thinks about this but I would prefer it necks up just before it enters the engine compartment.


Thanks for starting the list! I hope guys will jump on board. If you are trully interested and can put down a deposit please let us know. Before a deposit is needed you will be much more informed and have a very good idea of what to expect.

Since Corky builds his own system he didn't think there was much savings in elminating the self contained oil system. He also thought it would be much easier to install with no need to tap into the oil system and drilling a hole in the oil pan. He is putting a lot of thought into making this easy to install. He has talked about creating craddles that hold the components so that most of the kit can be built on a bench and then just lifted and mounted to the underside of the car. It would also be easy to put the car back to stock if needed.

Have him check out those oil less turbos to eliminate the self contained oil system. That should save some bucks. The Comp Turbos are a little more $ but there might be a cost savings. It's worth a shot plus I've been reading these turbos can be mounted vertically! Not that we'd need to just thought that was kinda nutty.

I went to the Comp Turbos website and it looked like the oil less turbo was coming soon. If the intercooler effect charge pipe works Corky thought we might be good as far as pricing and margin are concerned. I wil mention though.

I will be interested but I need to save money for about a year and a half because I have alot going on with the wife and a second kid coming in January. This is a steal though and I will eventually buy one for sure if there is one available when I have the money. I am also a owner in ridgecrest CA, which is hilarious because me and 2005 ragtop are 2 of 4, maybe 5 owners total in our tiny town of less than 30,000 people hahaha

I just had a thought, since we are looking at having this designed for stock N/A cars. Is the neck up from the charge pipe going to fit a 74mm throttle body upgrade? I sold my OEM throttle body a while back.

The bolt flanges for the ends are the same size between both 68mm and 74mm units, right? I know both units bolt to our stock manifold.

The outer diameter on both ends (intake and manifold) of the OEM throttle body is the same as the 74mm; the OEM just has a neck in it. That's why the 74mm is such an easy swap. So the turbo manifold won't know the difference.

You will be fine, but we have to let him know when they build your kit. My engine has the stock 74mm TB. I spoke to Corky briefly this morning. and sent him a long email we will discuss hopefully latter today. He really likes our cars and willing to take on some risk but his crew has had a couple of meetings and they get mad at Corky when he doesn't use deposit in a sentence. To keep his guys happy we will need deposits. He seemed overjoyed that we have three ready to send $200 since yesterday. we really need to get to ten if possible as that will allow some who need to save up more time. Timing should look something like this: John's car/protype will take up to eight weeks to complete. at the rate of one kit per week, the tenth in line is looking at another 2.5 months. Not sure how many weeks it will take to line up buyers willing to send a $200 deposit but once we have ten. Then we would send deposits and John would drive to San Antonio. Once John's car arrives buyers at the end of the list are looking at 4.5 months to be ready to purchase.

In my email today I have asked Corky to write something up on his letterhead describing the kit, cost, performance goals and conditions regarding the deposit and anticipated kit build times and delivery times. I told him about the recent success of getting deposits for the headers and Wavetrac but also mentioned when it comes to boosting the n/a Crossfire, people may be more skeptical. However, with Corky Bell (BEGi) involved along with Kleemann helping to get Corky up to speed on the unique aspects of the MB engine management we may never have an opportunity like this again! this is about as good as it gets!

We need to try to spread the word, I sure hope there are more than three of us that want in on this.

Lantana,
Put me down at the bottom of the list, but I'm in - NO DOUBT !! Let me know the who, where, when for deposit. A more accurate S.W.A.G for the balance would assist in determinig the level and length of poverty/pain.

Thanks tim,

No deposit would be required until all the facts are posted by Corky, He is working on a document now and hope to have it done by early next week.

Bri3D,

Thanks for the PM. John put him in the third spot.

2005 Ragtop,

Thank you! John can you put him in the 9th spot and put frank at number ten. Thanks!

Guys we are going for ten, This guarantees production and I don't have to beg and plead with Corky... Not that I wouldn't if I had too...

Looks like we are at 5, let's get to ten! Here is some information on who you are dealing with in case you didn't see this on the Bell Intercoolers website about Corky and his partner.

A recognized authority in the field, Corky Bell has served as engineering consultant on many successful racing efforts including the 1986 IMSA GTU class championship Porsche 924 Turbo, the SCCA Escort Series champ in 1994 with the Nissan 300ZX, and a Bonneville record setting Mazda RX-7. Bell is also the author of two publications on the subject, Maximum Boost and Supercharged!. Both providing essential, hands-on, advice for novice forced induction turbo and supercharger system designers.

Gerhard Schruf has spent the vast majority of his engineering career working in the field of forced induction. Having developed turbocharged engines for marine, industrial, street and racing applications, with power outputs ranging from 50 hp to 40,000 HP. Gerhard was also instrumental in the initial development of the unique, pressure-wave-supercharger, the COMPREX. A highlight in his career was working with Gilles Villeneuve and the Ferrari Formula One team, providing forced induction expertise during the teams early ventures into the turbocharged era. As an author and co-author of several SAE-Publications his focus always was on performance, but in conjunction with fuel economy and exhaust emissions for street applications.

I would rather not pull the cash out anytime soon as my investments are in the crapper (like everyone else's) but if that is what it takes to make this a reality, so be it. I am standoffish at the moment, but as it gets down to the line, I can make it happen, and will continue watching the thread to see if I am needed...

Nice to know we can count on you if needed. Thank you! We can't let an opportunity like this pass us up. As soon as I get the letter from Corky we will start a new thread and reference this thread for anyone who wants to know the history of how this came to be.

If I have to throw 200 to make this happen I can and will. That being said, when it comes to whatever position I was in to get the kit, I may need to be replaced by a few people while I come up with the rest of the cost.

and to think.... I was gonna sell my xfire.
