HIGH PERFORMANCE 4.6 LITER V-8 ENGINE


For those seeking the ultimate high performance driving experience, Dinan has once again redefined M3 performance with a bored and stroked 4.6 liter version of BMW’s V-8 engine. The engine produces 502 horsepower along with increased torque of 384 lb-ft at 5600 rpm. As incredible as BMW’s V-8 is in stock form, just imagine the acceleration that results from a maximum gain of 105 horsepower @ 6400 rpm and a maximum gain of 96 lb-ft torque @ 5000 rpm*! Equally impressive is the fact that all of this performance is available without sacrificing BMW-like drivability or the peace of mind that comes from matching new car warranty coverage for up to 4 years or 50,000 miles.

Dinan’s 30 years of BMW tuning and racing experience ensure that the engines will not only perform but also provide years of trouble free driving excitement. Much of the technology that has made Dinan’s Grand-Am Daytona Prototype engines both competitive and reliable has carried over to the 4.6 Liter V-8 engine program for the street, ensuring that the engines produce incredible power along with race-proven durability.

The engine is supplied as an assembled long-block, fully prepared to directly replace the stock engine without modification. Maximum performance is achieved when the engine is equipped with the optional High Flow Intake , High Flow Throttle Bodies, 16% underdrive pulley and Free Flow Mufflers, producing an incredible 502 peak hp @ 7500-7800 rpm and 384 lb-ft of peak torque @ 5000 rpm. For those seeking ultimate performance from their M3, without sacrificing civility, reliability or warranty coverage, the Dinan 4.6 Liter V-8 is the definitive solution.

Nice.

$30k fyrir 100hö.

fyrir utan $20k core charge ef maður lætur þá ekki fá mans eigin M3 vél

Rétt slefar yfir 108hö/líter. Þegar vélin var áður 105hö/líter.
Ekkert nema stroking í gangi og remapping.

Man ekki eftir neinum sem er að gera sambærilega hluti og þeir

S38B36------ 3.9

S62 ??

S85B50 -------- 5.7

S65B42--------4.6

voru þeir ekki með S50 eitthvað ??

en BMW M/// Gmbh bjuggu til allavega 2 S38B40 vélar,,,,,,, 408 ps mega myth í kringum þær

stærra rúmmál þýðir meira viðnám..

erfiðara að fá 105hö/líter úr stærri mótor..

en remapp og smá fiff ætti að redda því

BMW E34 ///M5

108hö er bara ekki neitt vandamál í dag.

stock mótorhjóla vélar runna 16k snúninga í dag. án vandamála.

Þetta snýst alltaf um að missa ekki low endið í bílum sem eru þungir eins og nýjir bílar eru alltaf.
Eða raða inn fleiri gírum til að fela þyngdina.

Ef einhver sýnir 120hö vél , þá erum við að tala samann. Það væri CSL mótor í lagi.

Jæja,, hérna eru þessir MYTH bílar frá M Gmbh


Officially BMW only built one (1) 400 hp car and that is GD64558, specially made for the sheik of Dubai. Adding to this another 2 cars had the same engine mounted when new. These 2 cars where however first built together with the other M5s, with a standard 3,8L engine (340 hp). The cars were registered with 250kW but the engine was then changed "off the record" to the 400 spec. One of these cars is very likely to be GD64559, painted in BMW Individual "Zyclamrot metallic", a burgundy colour. The car was ordered with champagne interior (tan leather). This car is also still alive, however with a rather high mileage of 245.000 km. The car was eventually exported to Turkey and now I haven't heard of it in over a year, but it is probably still alive in Turkey (with a 340 hp engine today). The 3rd and last car I dont know which one it is/was. But according to a member here it might have been greyish (Fjord grey) and driven by a Mr. Rosche, employed at BMW Motorsport. One could suspect this was built close to the others, meaning 11-12/1994. GD64543 and GD64561 are both built in the same time and painted in Fjordgrau. It might be good to investigare these cars further.

About GD64558, the car was owned by a member here and later sold to a workshop in Dubai. The car was advertised in 2005 and test driven by a person from Abu Dhabi, whom I have been in contact with. He tested the car at the residence of the owner. The mileage was about 65.000 km and the owner (a Syrian man) was asking USD 13,000 for it. My contact however thought that price was a little too much and did not buy it (he regrets it now though :hihi: )

Now talking engine specs. Unfortunately I couldn't get a very detailed spec sheet. The reason for that beeing that there are almost no documents left on this vehicle at Garching. Only a paper showing what was changed. No drawings, engine graphs etc. All engine parts are unavailable from BMW M and have been for a very long time. Most of them were ordered specially for this engine/these vehicles. The piston set and piston rings were delivered by Wahl (a fact), forged aluminium. It is believed that the compression ratio on GD64558 (and also GD64559 and the 3rd car) is 12:1, however I haven't got this fully confirmed in writing yet (dont know if I will ever get). Crankshaft and connecting rods are lighter (probably the same specs as listed by Chris Wagner on the old bmwm5.com site). According to Wahl these might have been (not confirmed by BMW - they dont have any documents on this) made by a firm called Werner Bauer Fahrzeugtechnik, this person is working for a company called Doettling Hagen GmbH, specializing in engine components (Porsche is one of their customers today). Both camshafts were changed, probably to 284 degrees as mentioned earlier by Mr Wagner). It is not known who delivered the camshafts or if BMW has made these themselves :dunno:
Other than these changes and the obvious remapping of the Motronic program (higher redline - probably 7850 rpm as listed earlier), the inlet ports of the cylinder head where slightly modified and larger inlet valves were mounted (sorry no mm specs on this - we will have to measure on Franks car :hihi: ). I didnt get an answer if the fuel injectors were changed, but I believe they could have been, because from the graphs I have seen the original 380cc ones are usually maximized at about 390 hp. Maybe someone else has a comment on this.
Intake was completely stock, air filter etc. Exhaust valves were stock, exhaust manifold was stock, catalytic converters were stock. The exhaust system behind the cats was however changed. Special setup from Boysen, custom made for GD64558 with a noise level that wouldn't comply with the EU regulations (= a racing exhaust looking like the original). The exhaust was however changed when the car was in Dubai (too bad!).
One interesting comment on this from the engineer responsible for the special engine, is that the cylinder head was NOT oil cooled on GD64558. This is a fact.

I understand a few people have an interest in this car (my brother is among them). No matter who gets it, let's hope it comes to an owner who changes everything back to as much factory condition as possible (engine specs, if possible + putting the contrast colour and amber indicators back on the car). Its only special if it is in original condition. What a waste if someone converted it to a track car etc!
I would be happy to answer questions through a PM, but this is basicly all I know so far :noSMG:
