A turbo recaptures some of the energy being wasted through the exhaust. It uses that energy to compress and force air into the motor.

I see packaging as a nice marketing tool for these turbos but again the ability to pass emissions with modern cars is what I think was behind this setup. The aftermarket is adapting to keep satisfying the need for extra speed.

It would be interesting to hear some turbo experts opinions (Corky Bell, Gale Banks, etc.).

They tout the installation as being basically the main benefit. Check it here:

There are many texts written about the turbos around the web as they have been around for several years. I can't remember which forum it was, but I did some "message battling" about those with some guys a few years ago. I was able to dig up all kinds of information about them from some of the bigger names in turbos back then so I would imagine there is probably a lot more out there now.

 

the simple answer is, hot air takes up more space than cold air. the hotter the air that passes through your turbine, the faster it will turn.

 

I was just watching horsepower tv. Apparently Bully Dog Performance (really big in turbo diesels) just built a remote turbo system for the '05 mustang. They claim install in ~2 hours. About 340rwhp (+80hp over baseline) out of 4psi. The system is designed for 5-8lbs.

 

off topic but does anyone know where to find a anti lag system(misfireing system)

 

Haltech ECU's do Anti-Lag.

 

I'm pretty sure MSD has a box you can use for an antilag system.

On the whole hot/cold air issue, the STS turbo kits make use of this fact by having a smaller hotside, thus since PV=nRT,(n= moles, r= gas constant) the same number of moles of air are in the exhaust, but since the temp is much lower, either the pressure or volume(or both) must drop, the smaller turbo allows for pressure to remain a constant, but volume to decrease.

The primary disadvantage to remote mounted turbo systems is lag, which is minimized by using smaller diameter tubing, which minimizes flow. Thus you must balance flow and volume (lag), this means you actually have to do math if it is for a custom app. Use the smallest diameter charge piping possible for the flow amount needed (determined by desired HP, and flow from compressor).

Feel free to correct me where I'm wrong, or add to it.

 

You need a special turbo for ALS- and they're not cheap. I know the makinen (sp) edition evos had them, i'm sure most of the big turbo producers will have at least one in the line-up but you'll probably need to call them to get nomenclature (and flow maps) on them.

 

wow alot of input lol. off topic on my own thread but i saw someone ask about the anti-lag system. i saw something a while ago and some sti was equipped with the anti-lag system and i'm curious on how that works...keeps the turbo spooling between shifts? that would be nice...

by the way yes the moles of exhaust gas passing through the turbine remains constant at whatever rpm, load, and whatever you are at. if a certain amoutn of moles of exhaust gas go into the turbo at a certain temperature (signifiying a density) then yes a hotter mixture of the same exhaust gas would be less dense at take up more volume. now heat itself is not what makes a turbo go obviously its the gas and it's density that create the pressure needed. it just depends on the final cfm of exhaust output is. you can have the same mass of moels of exhaust and depending on the temps (densities) the cfms will be different...
i hate chemistry

 

Here's a link for a primer on als.

It's hard on turbos, exhaust components, and anything close to both of the aforementioned components. I don't know that it's that useful on a street driven car.

 

Ive been thinking for a little while, not seriously, just coming up with some ideas. But would a setup with the remote mount turbo work well if there was a smaller, to4s sized, turbo prespooling the remote mount. As in a t04s at the front, and in the back, infront of the differential, a bigger turbo, such as a 42r(assuming there was room, havnt looked). The t04s would work just as normal, piped to an intercooler, and have the 42 up to the intercooler too, kinda like a twin turbo setup. I think if you had a prespooling turbo, it would make very good power gains, since a 42r makes good numbers as it as, if it was prespooled it would just make a larger power band. This could also be done with nitrous for spool, but i think it would be a pretty cool setup. No flaming, just throwing an idea around.

 

do you mean sequentially like stock? i think it would be hard to replicate a system like that with so much distance to cover with vac. lines and everything. unbless you mean to just use the first turbo primarily to pre-spool the larger one/..like use the boost of the small turbo to spool the large one? i guess...you'd have to get something with a small *** hotside and a nice big cold side to make it efficient enough to where you'd get enough boosted air fast enough to spool the big guy.

 

No, i mean completely parrell. The smaller one would spool up, and when it was runing at full boost, the larger turbo in the back, would then be spooling as normal, but would spool faster due to the smaller turbo prespooling it.

 

This is an interesting idea. Figure if the 600cc bikes can spool a snail why not the 13b. Although I guess the distance from the manifold is relative. It would be an interesting wait to retain the 6pt actuators for us NA guys.
EDIT: Noticed this was in the 3rd gen section. My bad. But its good info regardless!

 

i just found this thread and read it all.. and i think a remote mounted system would work well with the fd..

its funny you mention the dual turbo setup with the remote mount. i talked this over with the guys at sts not too long ago.. and they said they could definately do something like that. the only thing is.. its going to be a pain to do all the piping and vacuum lines for it. and it would be a good idea to heat shield the fu*k out of where you put the turbo.

i since decided to sell my car.. (somebody buy it please!!)
but i was planning on gutting where the spare tire goes.. and fabbing up a spot to fit a large turbo... gt42, or t51r, or something to the effect.. and i wanted to use a small turbo.. the garrett gt25 to spool the "big guy in the back" i have thought about doing this on other vechicles as well.. and it would require alot of fabrication.. the guys at sts feel confident in doing this (thats what they told me)
its just going to be expensive.

 

why wouldit be hard to do vac lines? 3/8 or 1/2 inch brake line, run it along the bottom and bubble flare both endes so the vac lines stay and zip tie em. you would only need a line for the PCV to the turbo inlet anyway, maybe for the oil injectors if your using a stock ecu. the wastegate line is just gonna go from the compressor housing to the actuator which is right there...of course a line for the boost controller too i guess...ut either way just buy like a 10ft roll of brake line and go to town
