Please, call and tell him to never talk to customer asking about Porsche products again......:rofl: I'm he'll listen to "Huster" the coolest cat on a bi+ch car forum....

Lol...don't break your back with that accelerator pedal. I'm in a build here, dont worry, it'll be done soon enough and yes, it will be faster than your $hit box, in every way. ;)

Why are you so concerned with my car again? You talk a lot of ---- about it but you fail to realize that it's a fast car, its reliable, and you'll probably incorporate something that I learned along the way that will save you money. Next time, instead of being an insolent ----, maybe consider the contributions some people make to this forum and that you might use some of our lessons learned the first time, and never realize the financial and time sacrifices of those who came before you.

Sweetie, you are ---- talking a guy with a running turbo Miata, when all you've got is hope and dreams.

Hell, even I've got a running turbo Miata which is a set of trials and tribulations unique to itself. Untill the day you get a running, reliable turbo Miata going, you may want to tone the ---- talking down a bit.

The same reason you go on a tangent and talk $hit in random threads that have no relevane to the topic at hand.

My posts in this thread were 100% relevant, most of the other threads there is a "relevance factor".

You've got the order wrong bro.

Post results, then talk trash. It's not talk trash, then post results.

Relax bro, he's busy masquerading as a Porsche owner on the phone.

Its way more fun the second way, given one rule, that you can actually produce results

Has anyone on here claiming to want/need to produce 500-600rwhp ever produced results after talking trash?

No.

Back on topic.
Our stock transmissions were designed to hold ~100ft/lbs-ish, plenty of people driving around reliably at double, even more in some cases.
Vane'd holset turbos may be designed to be reliable for 100K miles on a diesel engine, perhaps 50K is possible on gas. Anyone have any actual experience, please share.

I want to see Boost Joose' build thread to back up all the talk.
Post it up.

Don't forget to add that "long throw short power shifter" in that build too Mr Engineer.

I'm curious how would one control vanes.. as far as angle and how much.. rpm based? boost based? Rpm x psi graph of some kind? At last go E85 to help with the exhaust temps.

Why is OP such a butt pirate?

Ok for serial: I went to aerocharger site and looked at their biggest one... is it just me or is the compressor map pretty "meh"

Looks simple enough... Boost vs angle..

Ok, maybe I can get this thread back with some tech, lol.

One of the things nobody ever talks about with VGT turbos in gas applications is that they damp out exhaust gas pulses which can hurt spool (think the difference between a properly done manifold compared to a mediocre log manifold). In an app. like the 997 it doesn't matter much because the flat 6 pulses aren't even anyway, but in an I4 you can really take advantage of strong pulses to help get a larger turbine spinning. Obviously even more so in a twin scroll design. Not the end of the world, because the VGT can compensate somewhat, but its still one more factor to consider.

The real point, as Savington pointed out is temperature capability of the VGT turbine housings and vane mechanism. However, OEM small diesel apps are really kicking up the temp limits recently, especially in Europe, but I'm sure some will be coming here at some point, so there should be more choices in the future for people like us.

I can't even begin to describe how flawed this logic is.

BW has the BV50 VGT, over $3k for the turbo alone.

I'm pretty certain motec and v2 have ability to control VGT valving.

Yea, AEM probably lied to me so I wouldn't be the first Miata with vgt......lol

Maybe try this?

If I used it correctly, you'll need at least 26# of boost at 7500 to support 500hp.
26# of boost at 2500 = 389 Lb-Ft.
In the real world I would have guessed 30.

I half-assed it, left a lot of the parameters as-is. So it's not set in stone...
Maybe someone smarter than I could take a crack at it.
