pretty awesome, warriors already run hot, so im worried about running temps on that thing definitely an oil cooler on it and maybe an e fan...you gonna use any forged internals?
X2 for sure get a oil cooler.

the wheels are sealed only when the wheels rotate at certain speeds. they use air to form a seal to keep the oil at the bearing/bushing. which is why if you do not let the engine return to idle before killing it, it destroys the bearing/bushing. it destroys the bearing/bushing because of the inertia built up by the wheels and shaft. when you rev the engine and kill it, the oil stops flowing and the wheels keep spinning. the b/b ends up riding on the outer part of the b/b, screeching to a halt. at least that is what the manual said for the tc003. on the seca turbo, the turbo was ran low and at the back of the tranny. it had a surge tank, not too much different from an intercooler and reed valves. the disadvantages of suck through, are, according to this, http://forums.subdriven.com/showthread.php?4433330 , more lag than ever, destroyed seals on the compressor side, no availability for intercooler. pluses are that it is easier to run a suck through setup with a carb. by running the turbo this way, it seems actual boost will have to be set lower than 5psi. the reasoning is, when it picks up the fuel, the fuel will increase the psi. by how much, who knows?
WTF??
the reason you dont shut down a turbo engine right after running it, is cuz your engine supplies the oil to the turbo, and the water, if it has both.
you engine stops turning, then so does the flow. In the meantime, your turbo wheels are STILL sinning at several 10s of 1000s of RPM.. that in itself creates a lot of heat on its own, never mind when the only thing cooling it is cut off. Also, it doesnt have that slight film of oil upon everything keeping it lubricated, and that slight spacing cushion effect.
as for the surge tank, thats basicaly an guard against oil starvation. If the oil pressure drops, the check valve unseats, and incomes the pre-pressurized oil.
The problem with blow through seups, is you need special carbs setup for them, as a general rule.
Essentialy, if you look at a blow through, think of it this way, aside from an increase in turbulance, and forcing heat through the carb, everything in front of the turbo just acts as if you're at a lower altitude. Its the same as having a higher atmospheric pressure. Say 5 PSI higher than normal atmospheric pressure. So jet for your current 5PSI more altidude/atmospheric pressure. (Some very simple math there, which I dont know at the moment...)
as for a suck through, the carb basicaly just sees it as a bigger displacement engine, sucking in alot more air and fuel, but the jettings basicaly the same as a blow though, since in the end, the turbo is still cramming in the same amount of air, which needs the same amount of fuel.
as for no intercooler, well, methanol injection/chemical cooling could easily be rigged up if one wanted.
The only downside I realy see to suck through is the risk of the turbos heat preigniting the fuel in the turbo before it gets into the engine. This is likely one of the main causes of the seals failing. Kinda like a reverse BANG BANG/antilag/misfire system.. lol
just basic intelligence can guard against this. On the warrior, I dont think theres gona be enough heat, and speed comming through that turbo to realy need to worry about it.
I highly doubt the seals fail due to the contact of fuel.
On the exhaust side of the turbo the seals see tonnes of unburnt fuel, plus a crud load more heat.
As for the fuel causing it to pick up PSI..? Well the fuel in our warriors mixture is the only thing that cools down our engine aside from air flow. Would it not stand to reason that it would cool the charged air going into and out of the turbo as well, ?
Cooler air/fuel mixture= more mixture into cylinder = mo powa!! more boost!!
This is why all young lil ricers and street punks and such add an intercooler 90% of the time..
"OOOoo add an intercooler!! makes it colder and crams more air in = more power!!"
Not, oh, if we add an intercooler, we can run higher boost without the engine pinging or blowing apart because the lower temps prevent against pinging, detonation and pre-ignition, and general catastropic engine failure such as blasting pistons through my hood...
everything is simple math.
Surftouch:
Just curious, have you considered running a separate oiling system for the turbo? A little electric pump, with its own hoses and tubbing? Knda makes it more complicated. prolly simpler to go from the big bear adapter, to the turbo to the cooler then back into engine, )Or other way around o which ever.
or maybe, engine, to cooler to turbo to cooler to engine??
just wondering.
At first I thought maybe it didnt even have an oil feed on that turbo.. kinda puzzled me.. but then I figured what else could you be doining with that syringe in the vid..??
EDIT:
By the way, what is that turbo off of/what kinda turbo is it, make? model? what from??
well, thanks for all backing me up on that, got it all together and ran like dog poop, now ive got it all apart and thinking maybe blow through might be the way to go, the fuel just wasnt getting to the engine quick enough, it would start then die, i got it to make 3psi once, then it died, Im going to have to rethink all that I thought was a good idea on paper, The turbo its self is from an audi tt 1.8 t, this really sucks haha, I had some much time in it, and just to see failure. time to get back to the drawing board
