Very Stupid

I don't see any good reason of that car. A old piece of shit without any interior. Not a BMW anymore. I wouldn't enjoy driving fast for 2 seconds. If He would have to drive it fast than the whole car will blow. I'd smoke him with my 325i only because the car has to much wheel spin. And the car will never pull 152mph.

People do strange things with they're BMW's- Thats why there is Junkyard!!!

Don't get me wrong here lifewithbmw, but yo 325i will never smoke that car assuming that it really does have 750hp, even if it does wheelspin the whole way it will still eat your car as it has in the reigon of 190 - 230 hp(approx guess), but even if your car was at 300hp i would lose, it is like this more hp = more power = more speed, because the tyres will have to get traction sometime.

You obviously haven't a clue about "speed" or people with the need for speed, so I'm not sure if I should bother educating you by responding to your uneducated response, or just shutting my mouth and continue to marvel at what I think it one of the most awesome PURPOSE built BMW I've seen in a while!!

My car has two seats, it's loud on the inside, it doesn't have a radio, it doesn't have a CD, it has lexan on the back hatch, it has a fibreglass hood, and it lobs like crazy at idle, and it's gas consumtion sucks, it makes close onto 700+HP on the gun ... and guess what, IT MAKES A SHIT LOAD OF HEADS TURN at the track ... EVERYTHING I WANTED IN A CAR!!!!!!!!!!!

I seriously bet he could smoke a Lambo or Ferrari, think about it 750hp at what 2800lbs? thats 1 hp for every 3.73 pounds!! The E36 325i is what 3000lbs and has around 200hp, that's 1 hp for every 15 pounds...

The engine is acting just as it should. Turbocharged engines are low compression engines. Boost will build compression. Turbo's are for high speeds, not take off's. What there doing is fun but it's not telling the whole story. I didn't hear a compressor bypass valve blow off as he was shifting. Couldn't read his boost gauge to see what it was spiking too as it came on. Boy it did come on though. I think he had it geared too low, a common mistake guys do with turbo's. Once a turbo engine stops pulling, boost drops off and you can feel it nose over. Shwitzers are good turbo's, sounds like they had it running on the rich side, could see fuel smoke as well. They didn't have to make the car so ominus by adding the turbo and intercooler. Adding a roots style blower with it sticking through the hood is more like what these guys should have built. Superchargers make boost off idle, massive low end torque. These guys would have been happy.

As for racing this car. Beware!!!! Turbo's come alive way down the road in top gear. A 235i would take it starting off. Me driving the turbo car, I'd let the i car go at take off. He's not going anywhere so why bother outrunning it for 50 feet. Once first gear reved out, boost should be up. Second & third gears would go quick, somewhere the i car fell behind, it'd happen so fast you wouldn't have time to see the flash. Once in top gear things would really start happening. I know the front ends on these cars is wayy to light. If the driveline can take the huge amount of torque being made and the front tires stayed on the ground, it would be scary fast. They could have left all the interior in the car and added a roll cage. The extra weight of the cage would help stabuility at high speeds and keep the turbo working. Resistance builds boost. Just turning into a headwind will move the boost needle. Geared right, he's got a 200+ mph car there.

True, and not true ... yes they make lots of power on the high end ... BUT you can make a turbo car launch REALLY hard, trust me. I use a two step (a second rpm at 4500rpm) on my car. When launch I activate the two step and make anywhere from 8 - 12PSi while sitting at the christmas tree waiting for the lights ... that equates to low 1.6 60 foots at the strip, with late 1.5 60 foots if you're lucky on street tyres. For comparison, an American Mustang on a 10inch slick will run anyway from a 1.2 - 1.5 60 foot depending on the HP he's making ... and that's pretty much picking the wheels up off the line!!

I too didn't hear a blow off valve ... on my car I have the tensioner kinda hard on the bov, so you hear a very short powerful psssft (as opposed to the loud show-off noise the guys with show cars have) ... I want that BOV to hold the 34PSi I'm running at wot.

You're kinda right with this, but in the last couple of years the turbo bug seems to have bitten into a lot of hard core dragsters. I have a friend who's part of a pit crew for a guy running a turbo Mustang in some Mustang class (no idea which one). Their currently holding the record on the West coast, against the blown Mustangs and NOS Mustangs. If you want more info on this car I can dig up my notes and tell you more.

Sorry for the specific responses ... you seem to know turbo cars fairly well in respect to stock turbo cars, I've been racing them for some time now and just wanted to enligthen you to some misconceptions.

Inline 6 you need to study up a little on turbocharging.

"Boost will build compression" boost will change the air density, not the compression.

"turbos are for high speeds"

They are? Someone tell Saab that, and all the other new cars that build full boost at 2000rpm.

"Adding a roots style blower with it sticking through the hood is more like what these guys should have built."

Maybe you should go over there to tell them that. I'm sure that they weren't aware of that option.

"Resistance builds boost. Just turning into a headwind will move the boost needle. Geared right, he's got a 200+ mph car there."

No, and um.. no. depressing the gas pedal will build boost, not resistance. Extra weight doesn't equal resistance, it equals inertia which is not desireable in any race car.

200mph? That'd be a sweet gearbox.
