Lol haha okay okay - maybe toppling over was a little dramatic - but hey , u never know??

EDR - can u post some pics of the engine bay? also some Dynos would be really good .

 

If someone is willing to donate the funds to put one of these on my car, Ill shoot the video of the installation and of me driving it,.....away,......really fast......

 

Wow, my plan got pushed back with my engine problems, hopefully by June I should have the twincharged kit in my car. I'm planning on doing the kit along with the pistons that way I should be able to have more mods on it.
I saw the video and could tell immediately the difference in the power. Would definitely like to see pics, video, dyno, and some more figures. Congrats on the car, and hope to join the club by June.

dude !.......how bout some pics of that turbo engine bay mod city?

 

yes it was those gears and yes it was that fast.... wait til the pistons come and I can hit it with some nitrous on the top end....
I have pics of the engine bay but I can't get them resized to fit on this forum.... if someone wants me to send them to you so you can resize them let me know.

 

I can't wait for the pistons... I hit it a couple times at 30lbs of boost and it is flat out ridiculous. I have it running about 22-23lbs of boost at the moment with the mods I have on the car. Come on arias... I want to play!!!!!
the dyno and pics are coming as soon as we can get it all lined up

 

you can resize them in paint which is in your accesories. And if you have an apple, use iphoto.

 

had to publish to web to be able to get this stupid thing smaller....arrrrrrggggggghhhhh

 

Any chance of this working in the new steptronic automatic?

 

i give the little red devil 2 weeks before he holes a piston

 

clock is a tickin... it's been 2 weeks so far

 

If the idea of adding turbocharged to the car is to make more boost...why not make 20% or even 30% pulley reduction?

 

here is the problem with pulley reduction

it is exponential not linear in boost
plus the s/c has more parasitic power loss

 

uhhh....ok

Does your car still under warranty?...JK

Very nice...i want your car!

 

its still under warranty... or at least the windshield wipers are

 

I am interested to see how the tranny will hold up when you get those new pistons in there and really start to push the thing...

 

Don't you mean the other way round EDR?

SC's are linear, TC's are exponential. SC's are driven by engine revs which produces a linear "curve" and TC's are driven by exhaust gases which produces an exponential curve. The more boost added increases the exhaust output, which boosts the turbo even more, causing even more exhaust ouput etc etc.

Keep up the good work EDR can't wait to see the finished video

 

You're alsolutely right! :smile:

 

Phew! Thought I was going mad for a mo'

 

well, I am sticking to my guns...
when you twincharge it's not linear
the reduction pulley causes an exponential increase in boost
for example...
when you have just the pulley it boost around 14lbs
now adding 7lbs of boost from turbo would give you 21.... correct?
WRONG.... it would pound 30lbs easily and..... 20-25lbs at half throttle

Eaton said the same thing... not linear with the reduction pulley

putting the stock pulley back on and bam.... linear boost at WOT

but hey if you don't believe me... go with the reduction pulley's and find out for yourself...

peace

 

OK cool. I understand what you're saying but I think you misunderstood the original question by MyPocketRocket. He was saying why bother adding a turbo when you can just do a pulley upgrade on it's own to produce the same boost. Which is where I was saying that the trouble with SC's is they only boost in a linear fashion whereas turbos boost in an exponential fashion.

SC's produce good boost at low revs and build up boost in direct relation to engine revs and produce reasonable boost at high revs.

TC's produce little or no boost at low engine revs. As the revs increase, exhaust output increases. Eventually you reach the stage where the turbo rotors are spinning enough to increase boost pressure. The increase in boost pressure then increases power with more fuel and increases exhaust output, the increased exhaust ouput then cranks the turbo rotors harder, which increases the boost pressure again, which increases power with more fuel and increases exhaust output still further, which then cranks the turbo rotors even more etc etc etc.

This produces an exponential curve of power output to engine revs and means that although there is little boost at low revs there can be far more boost at high revs than the SC.

SC's are inefficient at producing high boost as a result of the linear output from them, turbo's are much more efficient but suffer from lag at low revs where no boost is produced.

This is the major benefit of a twincharged system. SC gives you good boost at low revs when the TC is doing little and the TC gives you good power at high revs when the SC would be struggling.

The best of both worlds.

However, having said all that, I totally agree that adding a reduction pulley to a twincharged car would result in an exponential boost. You can't just add the two boosts together.

Hope that clears that all up for everybody. Twincharging rocks :smile:

 

Now I can agree to that....
and you are right... it ROCKS

 

Jan - how about a pic of the seats you got? glad the turbo is working out well for you... can't wait to see it especially when you get the new pistons in......

 

Superchargers COST a lot of HP at high RPMs. This is b/c the faster that supercharger spins and the more air that it compresses, the more drag it is on the engine. So with equal boost numbers, the turbo will make a lot more hp up top. While a supercharger would make at least moderate power down low and the turbo would make very little if any. Twincharging is the untimate combination.

 

lets try this ....
