Another interesting Engine

[SyntheticShield]

I like new engine technology. So I scour around from time to time to see either whats out there or whats coming down the path. Well this time its a V8 for the BMW M3.

Anything interesting pop out at you about this motor:

That sucker has a throttle body for each cylinder.



Here is another look:

I found this very interesting as well:

BMW M3 V8 Spark Plug and Coil

Since the 1980s we've used knock sensors that listened for mechanical knocking. These are used to retard spark timing as needed. Every car has these today.

BMW has gotten very clever and electrically measures the spark plug gap to detect knocking, as well as misfires and bad combustion.

This saves cost and improves reliability because the extra knock sensors and their wiring are no longer needed.

BMW calls this "ion flow technology." Burning fuel causes ionization, and BMW measures ionization by measuring plug electrode resistance. (It took BMW at least ten paragraphs to say the same thing.)

Ferrari has been doing individual TB per cyclinder for years...

looks like another over engineered heavy pile to me.....

they've got to come up with new ways to justify the $$$$$ for their new cars, man!

I immediately thought of a set of Strombergs an/or Hillborn injectors. New version of an old technology. It's got 420bhp, at 8400 rpm, out of, 244 cubic inches, with a top speed of 155mph. Thats the kinda Pile, i wish i had under my hood!

Same effect, cheaper, and still yet, better than...

Ferrari/Lambo/BMW/Overpriced POS Cars.

You could get ITB's for the Buick V6 straigth from GM back in the day. I'm not sure if it's an LD5 that they were on, but I know they made over 400whp back in the 80's N/A on that 3.8L. IIRC it was for a road racing car.

It's in this book :

Amazon.ca: How to Hotrod Your Buick V6: Books: Ed Sessions Ron

A lot 4cyl gusy use GSX-R Throttle bodies for their ITB set up. They're CRAZY for throttle response and .. well you have so much more area to get air in. EVERY fast N/A Honda runs ITB's.

I'm thinking that BMW v8 is pretty impressive... 414 hp @ 8,300 rpm and 295ft-lbf @ 3,900 rpm. It is only a 4.0L though. And it is N/A. It's also lighter than the I6. But, really in all honesty is it really that impressive for the costs ?

The new GM Directed injected 3.6 V6 is making 302hp@6,300rpm and 272ft-lbf @ 5200 rpm.

ITB's larger cams for more revs and a better balance that 3.6 could easily make 360-380hp @ 8,000 rpm.

Apparently the BMW V8 is very well balanced with where the power is etc..etc.. and on the track it's not that much better than the previous I6 but street driving is much much better.

PS. IS it jsut me or does that thing look like a nightmare to work on !!

I would have no doubt that thing is a pain to work on.

and can only buy parts from the dealer (I've rebuilt a couple bmw's and most parts houses can't get a ton of stuff for them)

 

[SyntheticShield]

I cant stand stuff like that. If I buy a car I should be able to get what I need for it and do whatever work I am willing to attempt to it.

American cars, or Hondas.......thats what parts stores carry. They can get volkswagen parts...btu they have to order them most of the time.
