Remote Turbo?

These look pretty cool. The two concerns I had were:

1. The turbos seem pretty unprotected under the car.
2. The examples I have seen had the air intakes right on the turbos UNDER the car. Seems like a recipe for additional dirt and possibly water ingestion.

Too Much heat with turbos. Under hood, Intake, wear and tear on all underhood components.

A remote setup doesn't have the turbos under the hood. The only additional heat is from the boosted air.

run an intercooler and should be ok as far as heat. and the turbos are under the car, so the underhood heat should theoretically be minimal. i dont know much about remote turbos, but wouldnt you have to increase boost pressure to compensate for the distance? you would get a pressure drop with all the extra tubing, wouldnt you?

They dont do an intercooler setup with remote mount turbos, because they say that the turbos run sooooo cool far away that there is no need. Thats BS but thats their excuse. Boost creats heat (compressed air) bottom line, interooler is about the only way to remove it. Your other option is to not run an intercooler but instead through on some water/meth injection to cool down the boost. Remote mount will prolly have some crazy lag too.

Over the past week, we've been tuning out the drivability on the dyno with the help of our dataloggers, scan tools, widebands, and SCT Tuning's XCalibrator (which I might add is working excellent!). This gave us a good understanding of the ECM's ways. Spark timing advances/retards, trends of short and long term fuel trims, air flow meter readings, etc. Understanding and fine tuning these play a vital role in how well the car will drive day in and day out. It's fairly simple for anyone to tune WOT. Cruise, stop and go, and "tip-in" are generally overlooked.

Last night, we took our Mustang WOT for the first time since the Twin Turbochargers were installed. It's currently equipped with our Twin Turbo kit, stock air flow meter, 65lb high impedance injectors, ~3-4psi wastegate springs (with wastegate dumps plumbed back into the downpipes), high-flow cats, stock midpipe, and Ultimate Racing axleback mufflers. Some might ask why we're using such large injecftors. These are brand new 65lb high impedance injectors by Siemens/Deka. The beauty of these injectors is how well they work when pulsing low. They are fast reacting, and work better than our 42lb injectors! Anyhow, this test was to find the limitations of the factory air flow meter. We already have an upgraded air flow meter (which we will be testing next), but wanted to try this first. Sunoco 94 octane gasoline was used. Of course, we know that not everyone has the luxury of 94 octane, we will be releasing some 91 octane results shortly. The SCT Xcalibrator can hold 3 preset flashes. We plan to have 91, 93/94, and possibly a race gas map included with each kit. The kit is producing only 3.5 - 3.7 psi of boost pressure and we are rapidly nearing the limitations of the stock air flow meter. We are very pleased with the results.

Our Mustang Twin Turbo project has been put on temporary hold. Unfortunately, a solid solution for ECM reprogamming STILL does not currently exist. If you've been following our progress, you'll remember that we reached the limits of SCT's Xcalibrator software back in January. Since then, we have been patiently waiting for some kind of update. No such luck. If you wish to be informed of updates, please send us an e-mail with your contact information, and you will be added to our e-mail mailing list."

This seems to be what you're talking about. Notice the current difficulties they are running into. I have not seen a working turbo system yet for the '05. Be wary of those saying they have one (non racing of course).

You would need turbos capable of more volume, not more pressure.

I was talking to a guy in ATL that does custom turbo setups. He said he could do me a custom twin remote set up for $3300. He said i would be looking at 400hp at 4#. What are your opinions on the remote setups? Do you guys see problems with this type setup?

Thanks,

This setup appears to be commig more common along with the rear mount turbo's. And they certainly seem to produce some impressive HP claims.

Apart from the obvious exposed nature of the location the only other thing that may be an issue is lag. Having the turbo's mounted further away could increase lag time, according to some sources.

Best thing to do is try and have a go in a car with them fitted and see if you like it. Give it a good test drive 20 miles or so in varied driving styles not just WOT as see if you like the the WAY it produces the power as opposed to the peak numbers.

A supercharger will get similar numbers (perhaps slightly lower on a like for like basis) but the delivery and driveability should be very different.

Remote turbos are hardly a new concept. They are unpopular for good reason.

I suggest visiting the forums on turbomustangs.com -- you can find out more than you ever wanted to know about turbocharging a V8 Mustang.
