Callaway 240d turbo article with pics - willbhere4u - 06-26-2009 My dad is thinking about making a knock off of this car with his Rajay turbo kit RE: Callaway 240d turbo article with pics - winmutt - 06-26-2009 Fantastic but wierd. Callaway? 240D? Oxymoron? RE: Callaway 240d turbo article with pics - ForcedInduction - 06-26-2009 Maximum pressure by 60mph? 4psi post-turbo backpressure? Thats not very good, even by those days standards. I really like the seats and how they retained the air filter housing though.

Cool I guess, but it sounds like a sheep in wolf's clothing... bucket seats, "racing" wheel, and 15.5 second 0-60? Should be able to get way more than that out of 2.4 liters... just look at what the VW guys do with 1.6 RE: Callaway 240d turbo article with pics - ForcedInduction - 07-01-2009 The VW guys don't have to abide by emissions laws. 100hp isn't bad, its what Force Motors in India gets out of their 616a.

True enough, I'd just like to see 100hp/L RE: Callaway 240d turbo article with pics - willbhere4u - 07-01-2009 100hp but the TQ is 166 ft pounds what is stock TQ RE: Callaway 240d turbo article with pics - GREASY_BEAST - 07-01-2009 (07-01-2009, 10:47 AM)willbhere4u 100hp but the TQ is 166 ft pounds what is stock TQ I believe stock is about 100ft*lb. Substantial increases can be made in diesels by turbocharging and turning up the fuel a bit, but even so, the 5mm elements in the 240D injector pump are not enough. 4cyl injector pumps from other engines that push far more fuel are available much more readily than 5 cylinder ones, making the OM616 a better candidate for inexpensive diesel power. My only concern is that the cam is not optimized for this sort of thing, and I wonder whether the crank is up to the task. Turbo pistons and rods are abundantly available, and minor modifications (swapping the valves for turbo ones, as well as adding oil squirters to the undersides of the pistons) will make the rest of the engine easily as robust as the turbo version. My point is that a 4cyl superturbo making 100hp/L could be quite an engine, and really isn't that far out of the financial reach of most people here, whereas custom built injection pumps definitely are. RE: Callaway 240d turbo article with pics - willbhere4u - 07-01-2009 fair point you could built a bad ass turbo 616 and then get a "coupe 240cd" mount the engine back 4in like the 617 for better weight distribution back it up with a 4,5spd stick and have a really really nice car! RE: Callaway 240d turbo article with pics - tomnik - 07-05-2009 (07-01-2009, 11:53 AM)GREASY_BEAST the 5mm elements in the 240D injector pump are not enough. only the 200D has the 5mm elements, 616 have 5.5mm. Tom RE: Callaway 240d turbo article with pics - ForcedInduction - 07-05-2009 (07-05-2009, 07:40 AM)tomnik only the 200D has the 5mm elements, 616 have 5.5mm. True, but that still won't get it as much power as a stock 617a even if you max out the pump (about 115hp). Except for wanting to modify an already owned 240D, I can't see any benefit to not buying a 300D instead. The article was May of 83 so the turbo 300D had already been out for more than a year. A 300SD costs $37,000 and a 300D only cost $32,000. For an extra few hundred dollars over a 240D and a Callaway kit you would have more power and an engine made to have a turbo. RE: Callaway 240d turbo article with pics - CID Vicious - 11-24-2009 I wish I'd seen this earlier, very cool article. One wonders why they started out with the automatic - well, other than the fact that it probably needs the help most, being the slowest car in the line. I've seen someone make the manifolds from 617a manifolds just cut and capped. If one were to really go inside and replace the pistons and rods, perhaps the valves as well, I don't see why it wouldn't last a good long time at stock 617a pressures. Trying to chase down a modified 617a probably won't last too long, but one can only be sure by trying. Why would you want this instead of a 300D manual? Well, for one thing, I'll say this: even with mismatched front tires and gone shocks, the 240D is probably more fun to drive than the 300D I have, in the way it reacts and goes through corners, and feels infinitely more tossable. It feels like a Miata in comparison to the heavy nosed 300D. While it wouldn't be as fast as a 617a/manual, a 616 turbo with a four speed would be a good car, basically just being a middle point between the stock 240D and a modified 300. I know which route I'm going, and it has five cylinders, but I could see the appeal of this. Done right to a healthy stock motor, it would be easier than a full motor swap, which if you like your 240D and want to keep it, is your only other option besides leaving it alone. 166 lb ft would be reeeeaaaallllll nice going up the 14 or something like the Vail Pass, and for people who have to deal with going up grades in higher altitudes, it makes a 240D a more viable car. Besides, how hard would it really be to better the results of Callaway back in turbocharging's relative infancy? Considering the vast amount of turbos in different configurations, it couldn't be that hard to beat this seemingly pretty laggy conversion. I'll have to ask my old boss about these cars, he worked at Callaway for awhile (worked on their land speed record holding Corvette circa the mid to late 80's). He might know how the cars fared over the long run. The thing is, yes Mercedes went through the extra steps for reliability, but did they really have to in what was a pretty ridiculously overbuilt, undertuned engine? Maybe to see the kind of mileages we're used to hearing about now, but what's to say that a stock 616a with a turbo couldn't go 300k with what would be considered 'normal' useage? At 15,000 miles a year, you'd be able to drive it for 20 years if that figure were anything other than a number I pulled out of thin air, but you get my point.

RE: Callaway 240d turbo article with pics - willbhere4u - 11-25-2009 on my setup i used the original style exhaust manifold and the there was an adapter from it to the turbo would be hard to fabricate a new one for a different style set up! also some one in another post proposed taking a coupe making a 240cd and relocating the engine back 4-5 in like a 300 and move some weight towards the center of the car!!! RE: Callaway 240d turbo article with pics - CID Vicious - 11-25-2009 It's a great idea, if you can figure out how to mod either the X member or the oil pan. The 617 is a 616 with a cylinder added to the rear, essentially, at least in how it sits in the 123 chassis in relation to one another. Move it back the four inches and the pan and X member are trying to occupy the same space. It would be just as easy (or not) to do it to a sedan as a coupe. You know, if someone is willing to wager a 616, this might be worth pursuing, considering the injection pumps that become available for use. It'd be fun to see how far they'd go before they burst . I'd think they'd be cheaper to come by, too, since everyone wants a 617a. That smell and noise are the gears turning in my head... I think it was over at turbomustangs.com or something, but there was a guy who got into Car Craft with an 80s Firebird running TPI and a stock, two bolt main 70's era truck block. Nothing special or cutting edge about the motor itself, and I think they used megasquirt or somehing like that to tune it. They ran it with twin turbos and nitrous and got about 600 hp out of the stock block. They said something like "When you engage the nitrous you can feel the mains squirm a bit, but nothing's come apart yet!" And that truck motor wasn't anywhere near as over built and under tuned as the 616. Who knows, with the right injection pump and VNT, maybe swapped in turbo pistons and rods, the 616 might be a sleeper, especially with more modest goals than a sub 10 second quarter like the Firebird...until the Finns come off some of that 5 cylinder pump knowledge, we're kind of reduced to taking shots in the dark. Hasn't anyone tried reverse engineering the Myna, anyway? RE: Callaway 240d turbo article with pics - ForcedInduction - 11-25-2009 (11-25-2009, 06:02 PM)CID Vicious Hasn't anyone tried reverse engineering the Myna, anyway? Not much to reverse. Their main attraction is the 7mm elements and bench tuning from experience, the rest is external in a custom ALDA and a "full load adjustment" rod on the rack emergency stop lever. If the Chinese 10mm MW elements work out well, there really won't be much of a need for Myna anymore... RE: Callaway 240d turbo article with pics - tomnik - 11-27-2009 (11-25-2009, 11:44 PM)ForcedInduction(11-25-2009, 06:02 PM)CID Vicious Hasn't anyone tried reverse engineering the Myna, anyway? this is the case not only since the Chinese 10mm MW are up... I ran larger MW since nearly 2 years, perfect quality! But if you go for after market crap and smoke and rough running is not an issue, go for it. Bench tuning is not rocket science and all the external ALDA stuff is just because they had to use the M instead of the MW, cause there are no suitable after market MW elements.

Wait, you have/had a turbo 616? Or just the photos? I'm thinking this could work out very well for me, get a K26 and exhaust manifold and the related lines and such from pick a part, and my 240D/Auto that I'll have leftover from converted teh 300D to manual would be a much more useful car. Those results shouldn't be hard to replicate or improve upon with a K26, and if it's anywhere near 170 lb ft (which is all the bigger 617a makes stock anyway) I'd be quite happy. Always better to have two running cars, especially if you're screwing around with one of them. I figure if the car doesn't do as well as I think it will, the world will lose one 617a manifold and I'll have a spare turbo kicking around, and lose a few hours of my life tilting at a turbo 616. RE: Callaway 240d turbo article with pics - ForcedInduction - 12-02-2009 Just the pictures from my archive. RE: Callaway 240d turbo article with pics - Graminal95 - 12-02-2009 Thats my manifold your talking about, and I say if you have the will and the time go for it. My 240Dt has served me well over the past 45k miles, and yours should to. Just don't expect a huge increase in torque unless you get a little VNT. I can make boost in the upper RPM's but down low she is still a bit of a dog, on par with my Pa's 85 (2.88 diff) auto 300DT. On a side note anyone know the inner diameter of the prechambers in the OM60X series? |
