you should read this before producing end tanks.....

this is proper end tank for 996/997....

 

Nothing against this guy, as for the most part he is correct, although I think he "stumbled" onto most of the data. It looks like a highschool or freshman level college project and I have no doubt that his current knowledge would have incorporated a few other factors. The formula for FLOW is correct although he forgot to quantify the rest of the data. Without getting into too much headache, you also need to factor in gas(fluid) expansion due to heat(remember it can be 400+ degrees leaving the outlet of the turbo) AND pressure(as with a questionable core, the pressure differential can be substantial - and more pressure, more heat, more loss of efficiency). I would have liked to see this performed to a little more realistic level as far as pressures and heat go, not just flow. Definitely correct data though

please notice that he focused on the endtanks, that was critical for him in this test.
so you think quadrangle endtanks are better?

 

How exactly did you reach that conclusion from his post? He was pointing out things not taken into account in the paper you linked. You might want to read his last sentence a little more closely....

 

I'm sure SECANS are great units, but from what I've read, they are amazingly expensive... For ME, I'm moving from X50s to something else that will certainly be an improvement... Any of the units discussed should do the trick and be a radical improvement without breaking the bank...

now those are work of art. how much? 25 grand?

 

hey markski, check out the real deal. i think they use these on f1 cars. you're an expert on intercoolers now? i think i'll go with awe. wish i could afford those seacans though

 

Hrm, are you an expert? Why would we listen to you exactly? You THINK they are used on F1? That exact cooler? Really? Or are you not sure?

You're going to go with AWE... okay why? And why should anyone follow your decision exactly? I mean based on your obvious volumes of experience doing... what is it? You're basing your opinions on... looking at pictures of $25K intercoolers?

I'm still scratching my head as to why anyone would listen to you as opposed to someone who got off the couch, BUILT intercoolers, put them on cars, and did dyno runs that showed improvements. Frankly, while Mark's may not follow the same design as others and could in fact have flaws, his opinion trumps yours and your cheap shot pretty handily.

Thanks for adding pretty much nothing to the discussion. Others who have had some criticism have managed to pull something together that's at least somewhat constructive. Complete coherent sentences would be helpful...

 

Um , ok so they may be better and say you gain some extra power but at 25k is it worth the difference? Lol seriously I don't think so! So just lay it to rest.

Also Alot of 1000 whp cars over here are running as you call them"quadangular" end tanks , and putting the smackdown on all of the competition overseas.

 

Lol@yimma !!! Enough said .

Sounds like your butthurt about something?get some sand in your mangina?

 

I wish I could find a customer in Poland as I would set him up at cost with my 800hp kit.. trust me that you guys would need something strong to compete... and all that for 1/4 of the price... you ever wonder why Switzer is beating everyone up in Russia with his 997tt builds?

I have nothing bad to say about Secan... if you can afford it God bless you... I am sure they are far and above being 1st class...
All I can say is that I developed ICs on a few cars including mine and we put down 1000 to 1100 rwhp... all that on my ICs... so here take a look at these dynos and a 60 to 130... not bad for a Polak...

Im going to knock you out on this one LOL ... Albert is my good friend who lives in Chicago, is an engineer, and did my first end tanks 4 years ago... and wrote that study you just quoted... here is my proof...
BTW, they did make 871rwhp... I now make another 150+rwhp...
take a look at the pics from my car 4 years ago...
I am not competing with Secan... nor saying mine are better... what's up with your hostility?
any questions?
marek

 

Woof !

Once there is a high pressure area built up in certain areas of the end tank, and there are various velocities to deal with, do YOU think it matters as much as to the absolute design of the end tank?

Additionally, are you telling me that heat and pressure do not affect the flow through the endtank itself? I was merely pointing out that the data is inconclusive in a turbocharged automotive application. More information is needed, that's all.

I suppose a trapezoidal quadrangle design would be the better design out of the quadrangle designs. Incidentally, where did I say that a quadrangle design is better than one without any angles?

For sure they don't use them as INTERCOOLERS on F1 cars

They might use the cores for differential coolers, engine coolant radiators, or any other fluid cooling, but all F1 cars for the last few years(since 2006, I think) have been naturally aspirated. Last I checked there was also a constructors hold on new engines meaning for the next few years, they won't be going back to turbocharged engines anytime soon. This sucks as I really liked to see them push the forced induction envelope.... I guess the next natural progression will be 100% electric Formula 1.. that would be cool. Might be a little too quiet though.
