    • A look at Budler Motorsport's 7-second turbo S38 powered BMW pro-mod drag car

      A BMW drag car built in South Africa? That is what you have here from Budler Motorsport. They chose the classic S38 inline-6 to be the heart of the drag car and BimmerBoost thinks that is a great choice. The motor tops our list of all-time M engine afterall.


      What kind of power is it making? Good question. Quite a bit considering the car is running mid 7's at over 185 miles per hour.

      Details are somewhat hard to come by on this build as specifications are not provided and there is not exactly a ton of media out there on it.

      What we know is the quickest run is Budler Motorsport's 7.49 @ 298 km/h at Tarlton International Raceway in South Africa.

      Beyond that, BimmerBoost compiled what media there was to find on the car which is posted below. A shame there is not more info on it.

        Why the S38? If you have to ask then it is a good thing you are not compiling this list. This is the first true M motor, the one that started it all. A buttery smooth inline-6 with individual throttle bodies that set the standard for all that would follow. It is based on the M88 motor which can really be considered the father of all M motors as it was included in the very first M car, the BMW M1.

        If BMW themselves saw fit for this motor design to go into what they specifically titled the first of all that is M, who are we to argue? The M88 was turbocharged for Motorsport use way back in 1979 where it was said to make over 950 horsepower and used in Group 5 racing starting in the 1980 season. 950 horsepower way back in the 80's. If this is not an M engine design that has stood the test of time, what is?

        Now of course with the introduction of the S38 for the E28 M5 the M88 design saw some changes although the bore, stroke, and cylinder head all carried over. A dual-row timing chain, different cam profile, internals with a different compression ratio, and a catalytic converter for emissions reasons were the major changes. Log headers were introduced which was a cost cutting effect of the motor going into a sedan so there was a performance penalty versus the M88/3. The S38 would see duty in the E28 M5 and E34 M5. The motor design was so stout it was seen fit for two generations of M5's undergoing minor evolution for the E34. No other BMW M5 motor can make this claim. This motor also saw double duty in the very first M6.

        The S38 eventually reached 3.8 liters of displacement with the S38B38 fitted to the E34 M5 producing 335 naturally aspirated horses. BMW pushed the S38B38 very far considering it was a street motor as the spacing between cylinders was even more narrow than that of the version used by BMW in Motorsport.

        The S38 remained in production until 1995 when all was said and done. This is the same basic engine design that was used by BMW since 1978. There is no other BMW M motor that can make the claim of its design seeing use in three separate decades. There is no other M motor that more deserves the first place spot. There is no other M motor as storied or with such longevity. There is no other M motor that started it all. This is the first, this is the best, and so it shall always be.

        Incredible.

        I wonder what that cost... and I would like an S65 version.

        Its rather hilarious to see these performance figures and compare it to the numbers put down at the GTR world cup last weekend. Not even anywhere near top of the hill...

        "7.54 @ 192MPH - New GT-R Alpha 16 ET and MPH records at GT-R World Cup!!!! Tuned on the stock ECU with a Cobb Tuning Access Port V3.
        MODS:
        - Boostin Built Aluminum Rod 3.8L
        - AMS Performance Alpha 16 Turbo Kit (Not the "16X" kit)

        This is a BMW I6 design from the 70's...

        No fancy DCT either.

        I mean, i get it. But still, these are street legal mostly full weight GTR's versus a tube chassis dedicated drag car...

        I'd put my money on the drag car versus any GTR in the world.

        I would certainly hope so, but its still crazy to think the GTR's are in the conversation.

        Those GTR's are drag cars.

        They are all different flavors of drag cars. The info i posted above is a street car build. There are 11 second N54's with more mods than the GTR i posted!

        Look, I agree the GTR is impressive. But the GTR's that can run with this car maybe make one successful pass before something goes wrong. They are also purely dedicated to drag racing.

        I spoke marius from full boost today..the car ran a best time of 7.39 at 300km on 30psi of boost and has only had four passes so far..Those gtrs are 60to80psi

        Arbitrary measurements of backpressure in chargepiping is rather meaningless in this context.

        How is this meaningless? I'm just indicating that this car has a Lot more in it..according to Marius this car has 500bhp left in it with higher boost..the only gtr in the 6s so far cost enough to buy a small island with trial and error according to the owner..

        How come Budler doesn't have a good website or details on what they do?
