New type of turbo, want to see what you guys think Options

[FallenHero]

Hey, granted this really isn't celica related, but it could be addapted to be.

Go to www.ststurbo.com and look around.

I would have put this in OT, but I knew I wouldn't get all the traffic I would here.

The turbo's on the cars listed are placed just before the muffler. I wanted to see your opinions on this.

Very interesting information and the system looks clean,we are talking for something bolt-on so you are not expecting so many things.Its weird looking for turbo monifolds,downpipes etc.....hmm...and very clean work that saves a lot of space in your engine and keep it cold.
What i dont like its the air filter close to the ground,i have seen a lot of bad things happening from this.
Thanks for the info FallenHero

[FallenHero]

yes, but we both know re-locating an air filter is as easy as filling your car up with gas. A few bent pipes and you're good. Plus, with a FWD vehicle like the USDM celica, there is plenty of leftover room between the back wheels for a system similar to these to be completely hidden away.

i just looked through there and watched some videos and its unconventional but it could work well

I think you would have major space problems on some smaller cars though.

Wow, neat.

Problems: 1) You need to get a new exhaust manifold; and exhaust to the turbo by the muffler anyway; because stock isn't large enough to handle the turbo'd airflow.
2) More turbo lag? It seems like there'd be a lot more piping here than even a FMIC setup. With this setup, the exhaust gases actually have PIPING to go through to spin the turbine- that seems to me it equals a lot more lag- and if you wanted an IC; you'd still have even MORE piping.. However, the temperature gains by not being located in the engine compartment are nothing to scoff at.
3) Emissions legal my ass. This would only pass a visual inspections check; measuring emissions at the muffler would still result in too many pollutants for an N/A car- ahh! the jig is up!


After reading further:
1) They even admit that the stock manifolds and exhaust systems are restrictive, but say it doesn't matter because they lower the diameter of the piping to increase exhaust flow to the turbo.. IE, smaller turbo.. but they don't mention the fact that exhaust gasses will be slowed down int eh first .01 seconds of leaving the engine..
2) Apparently there's a built in IC, and they're using an extremely small turbo designed only for 5-6 psi of boost.

They don't provide an answer to my #3;

All in all, it's great to see new work being done with turbochargers

It looks pretty legit, and the video clips I guess you could say "prove" it. Just wondering, but, wouldn't hydrolocking still be a problem with a system like that? Still, I think in the future this system will be perfected as I'm sure that our turbochargers of today were once doubted as well. I'm excited to see how all this turns out.

They say it's "not a problem" on any vehicle they tested (hydrolock) to which I have to say: BS.

They're just testing it in applications where they know it won't splash up; etc.

"Splashes from huge puddles! water flying over the truck!" = water not going UNDER the truck.

However, the placement of the turbo isn't all that bad- far away from the front tires and to the sides/in front of the back tires.

As for boost lag; they claim it to be nonexistent..

And they've probably engineered it a certain way.

My 2 cents: Take this as an engineered as is for 5 psi. Any tuning to this would result in power losses, boost lag; etc etc. It probably does what it says it does, at 5 psi.

im still not sure what it does? is it just a regular turbo just mounted under the frame?

[FallenHero]

Here is how I saw it: As far as lag goes, you will get a bit from having resonators and cat's and such before the turbo, but after the turbo there is NO restriction, so it should equal out in the end. Plus, the LONG piping back to the intake would cool the air down quite well, especially if you use aluminum piping.

guys this isn't anything new.. when i was younger my grandfather told me this was done to MB trucks.. the turbos were put on the exhust pippies.. cause it was easier to take off and rebuild.. but they do work well ... but for the price of one of those system.. you can get a conventional turbo system or a ripp mods supercharger ..

[97sccelica]

remote mounting works by using smaller turbos(exhaust side anyway)

like said above

but

its pointless

4cylinder cars dont flow enough exhaust to spool a turbo with the cooler gasses at the end of the exhaust system.

the cars they use ar v6 and up, with 2x the displacement of out engines, atleast.
