The total power is a bit underwhelming but I can definitely appreciate the work and engineering that went into it. To put it in our terms, its like one of our 6.0s making 4200hp

 

I found the link on another forum.

Here is a follow up to the thread, about the guys that make the turbos



It ends up that Extreme Tuners have misrepresented their achievements. I hope it's out of rookie enthusiasm, not a sad attempt at ripping people off.

Here are some of the issues that have been raised on ET's thread at evolutionm.net:

-- He has represented parts others have made as his own.

-- He has implied that he's in partnership with McLaren when, at best, he's a customer (he apparently needed their help to come up with a 4WD traction system that could handle the insane amount of power his engines put out. He actually has the word "McLaren" on the uniforms his people wear!)

-- There are reports that the cars in his videos were seriously damaged after they were drag raced, eating away at the implicit claim that these are reliable designs/builds.

-- He's nowhere near delivering parts he was paid for a long time ago.

-- His distributor in the US can't get promised inventory.

-- He actually put up pics of his welder working on proprietary manifolds and exhaust systems. The problem was that it was easy for other welders to notice that the rig wasn't activated (they also noticed that the surface welds were largely cosmetic, that what was underneath would disintegrate under heavy use.)

-- He reports crank hp based on hub hp, hub hp being a very easy number to increase without actually increasing crank hp. Worse it seems he's done just that (hopefully innocently.) Compounding that incredible error, he claims his hub numbers represent 75% of crank hp, which is way, way off (it's more like 85-90%, which brings in his actual crank hp much lower.)

-- Well-known pros have challenged his numbers, his understanding of engineering basics, etc.

I hope this nonsense ends soon and a person that seems potential- and motivation-packed takes the necessary steps to thrive.

I apologize for any inconvenience and time wasted.

(Man, his parts look good, though . . . )

 

Heres my concern, and this has nothing to do with Jarrett's post:

Using Titanium on certain parts is fine but Titatium isn't used as a primary metal for two reasons, it's hard to work with, and it's expansion/conractive properties and ductile properties are not condusive for some engine applications. I'm sure these guys took into account the expansion properties of Titatium when they speced out some of those parts but the one worry is that Titanium is not necessariy a HARD metal, it's strong but steel is harder, meaning it doesn't bend or give as much, where titanium can deflect from its pre-determined form repeatedly before breaking.
Basically I cant see that motor living very long with so much titanium at it's fore. However I'm no metalurgist so Im sure there's a few things I haven't thought of or taken into account.

 

I dont know if your read all the info or not, but it does say somewhere in there, if I recall, that the lifespan of the parts are very short. So basically what your're saying has been accounted for.

 

wow now that engineering
