That should make over 2000 horsepower! I saw an ad in some crazy american car magazine about a quad turbo'd 350, and it made something like 2100hp, or something astronomical like that. A 562ci motor with 4 turbos should make enough power to break your neck at 100mph... Or at least feel like that. I wonder how much boost its running and how the HECK the heads stay on?!

 

He just needs a little N02 to make things interesting

 

That thing got way to hot.
Wonder what the EGT readings looked like.
Has to be a reason it's that cheap what do you
suppose just one of the turbos cost let alone the management system.
Either a hell of a deal or a slag paper weight.

 

it looks like its on a dragster. Why put quad turbo lag on a dragster?????? - Ruf

 

This could be an interesting thread...

As I understand it, turbos make more power than superchargers. They may have lag, buit on a dragster, that is a good thing. It is like a staged nitrous system. You don't want all that power right off the line, or you will smoke the tires, and go nowhere. You want less power at first, and then you will make even more power down the line. Turbos do not suck up any engine energy to run. They take waste exhaust gasses, and make boost off of something that is usually not useful. As I understand the stories, the NHRA initially let them use turbos, but realized that the turbos were doing *too well*, and the problem with turbos, is that they do not look as impressive, or sound as impressive, as a big bug catcher, with open header pipes shooting flames straight up. So they banned them. Same thing in most other US motorsports... Turbos are not allowed, even though they make more power than normally aspirated, or supercharged engines...

 

IN the end, a Turbo will make more Power. That is such a black and white statement, and since this is a 928 board, it needs to be qualified with some other info.

The turbos put MORE heat into an engine= 928s are too hot anyway
Turbos need extra plumbing= 928s, especially later years, don't need any more complextity

Turbos are great. 951 guys regularily make power that would embarrass a GTS from 60-160.

But for the 928, a nice, well polished Centrifugal supercharger out in front REALLY wakes the car up. Less heat. YES - ALOT of parasitic loss. BUt I don't think I will mind when I have 600hp to the wheels.
I will just make sure I have a SPECIAL bolt made for the Crank pully bolt! ARP does custom bolts, right?

 

... turbos.. superchargers... It doesn't have to be either or you know! How about a sequential supercharger/turbo configuration like the Lancia DeltaS4 rally car? They got something like 500hp from a 1.8L engine... heh, heh... <img border="0" title="" alt="[Wink]" src="wink.gif" />

 

The most impressive tubocharged engine I've heard of is the 1,5 litre BMW F1 engines. 1200 hp during race and 1500 hp during qualification runs.

1 hp/ccm at 5 BAR's..
