The video euthanasia posted of the vortech powered car was against a stang with twin turbos

selfinfliction... listen if you don't like it... just leave.. There isn't a reason for you to be in here. Please do the right thing and leave

Haterz gonna ______. Maybe he thinks he's actually accomplishing something?

Agreed, there has been no contribution to this thread. He is only trying to start a fight.

Ive never known anyone from ky to act like that either...pretty sad

even on a top fuel car if the turbo were allowed.. and created more peak hp.. it would not have the same response.. and when ur talking about a 4 second pass.. no time for error or delay

Finklestine

Not to be argumentative, but if there were turbos on those beasts they would have them spooled before launch and not stop boosting until the run was over, it's not like driving with turns where you come on and off boost...

first off... great job, even if it doesent have great results (which i doubt) its nice to see people still trying to innovate new ways to go fast on this platform.... and turbo cars would fail hard as top fuel dragsters...... you know the size of the turbo you would need to produce 7000+ hp??? you will never rev the motor high enough to be at full boost!!

Top fuel cars don't have torque converters. So how would they bring the rpm's up to spool the turob/s ? Large pizza to go please lol

Any ways heres what the guts of a 1600ax looks like folks.

So that's what the inside of a turbo looks like, who would have known

Also mostly all top fuel cars will blow pieces of engine through the exhaust every run, like the spark plugs (because they run like a diesel for the last 1/2-1/4 of the track it doesnt matter). AND did you ever wonder why they run zoomies (ie header runners with no collector?) which that is giving up a good bit of power? Its because their exhaust gas temps are so hot the collector would melt and fall off partway down the strip, imagine what those kinds of temps would do to a turbine housing? Can you say ball-o-slag before the run is over?

Finklestine

Air-bypass anti-lag system should do the trick just fine, but if they do get as hot as leafy says then that could be an issue even with inconel parts. The debris is probably the biggest issue though. I didn't know they were converter-less, what do they use?

Leafydialupking

They use a stack of friction disk clutches that fuse together as the car goes down the track. They dont even shift gears any more. Just launch it and as the disks fuse together it acts kind of like a cvt. And then at the end of the run they have to pull a hunk of molten slag out that used to be the disks.

oooo, blower ****!

looks like 180* twist on the screws, and they look so short! haha oh and thats a FAT 3 lobe haha

selfinfliction

with that massive amount of unburnt mitro exiting the engine, it would serve as its own antilag system without needing electronics to modify the timing. they would actually need a system to keep the wastegates open until launching

selfinfliction

beat me to it but the heat is not an issue, they could use the ceramics and coating process that is used on jet turbines, that car wouldn't see a fraction of the temps those things do

mrbelvedere

iTrader: (3)

it depends on what jet engine you are referring to and for the most part they are mainly worried about egt not can temps the other main reason you wont see a turbo on a top fule car is the blower is way more adaptable to to the conditions and the instant on power it delivers

Leafydialupking

Well actually modern turbines see temps only a little higher than that required to melt steel, though the higher they can get the temps the better for economy. And even the ceramic turbines are being run at temperatures above the melting point of the material, they are just cooled efficiently enough that the air temps can be above the melting point of the material but the surface of the material remains below it. Pretty neat actually. Since the temps reached in the exhaust is hot enough to melt a steel (Titanium?) collector (due to the heat pocket formed, which you dont get in the straight pipe, but would be even worse in a turbine housing) in less time than it takes the dragster to cover 1000 meters (the top fuel dragsters no longer run the whole 1/4 mile because its too dangerous or some ***** reason). I hope that sentence wasnt too confusing with all the parenthesis in there, just read the sentence without them and it makes sense (they're my little comments, like tool tips).

soooo thats some nice looking internals

the exhaust is 2000 F. at a velocity of over 2,400 feet per second and they did open it back up to a full 1/4

Yes and back to the topic of the twin charge. If done right with this blow it would be amazing. You see, this blower flows an ass ton of air, but it starts to struggle at high pressure ratios. So if we can keep the pressure ratio somewhat sane with a huge pulley, like under 2 and put a very large turbo on it, lets say limited to 10 psi. So when you first start you have some killer torque and airflow from the blower (and a maximum manifold boost of 15psi), this helps spool the turbo way sooner than it would otherwise. Now the turbo is spooled up and putting out 10 psi at the inlet to the blower, the blower will then be putting 35 psi into the intake manifold, but it will still be at a pressure ratio of 2 so it will be still very efficent. What you get is a metric ass ton of peak power but a broad torque curve.

You dont get this with the mp62 because it doesnt flow enough air to be worth it, this would also be amazing with the M90 blower. I think though that with the M90 and the AX1600 you would need a under drive crank pulley to get the pressure ratio low enough.

Oh sweet, this time last year they were still running the 1000 meter.

i really dont see any blower other than the m62 being efficient for a twin charge...and i dont even think anyone still runs a twin charge setup, they wised up and went straight turbo

Turbo Chargers are illegal in Top Fuel.

I'm happy to see that you guys are making this work.
