You could y pipe the single back into a dual exhaust if you wanted. I would probably add some resonators as well.
I would love to have a rear mount turbo and am pretty much stock with that option only because im not getting rid of my custom long tubes i just had made.

Does look nice. For dual exhaust, you could run twin turbos Also, correct me if I'm wrong, but a BOV is on the intake side, to vent boost on closed throttle back to the intake side of the compressor. A waste gate is on the exhaust side. But I do agree, I would want it routed to the exhaust outlet. But I guess the fabrication would be a little more involved.

Having actually installed turbos the blow off valve is designed for the extra air pumped into the charge pipes because the turbo has built up boost and the throttle had closed. The blow off valve vents the extra pressurized air to atmosphere so its easier on the turbo bearings and so that the turbo doesn't get slowed down as much by the pressurized air. That way it spins up more quickly when the gas pedal is pressed for the next gear. Venting the blow off valve to the exhaust is CRAZY. Now as far as sound I prefer venting the blow off valve to atmosphere directly and not into the intake tube. Also if you have a big enough turbo, venting the blow off valve into the intake tube before the turbo can cause tuning problems because it can actually blow air back out of the intake filter fooling the MAF and causing driveability problems. Been there done that. Waste gates bleed off extra exhaust gases so that the turbo doesn't produce too much boost, adjusting at what PSI the waste gate opens is how do set the boost that the turbo will produce. Venting the waste gate to atmosphere sounds like ass and I prefer that to be blown back into the exhaust after the turbo. Also an FYI a blow off valve is the name for valves that blow extra compressed air from the turbo to atmosphere and not into the intake tube before the turbo. A bypass valve is the same as a blow off valve except it blows the air back into the intake tube before the turbo.

were you be running a BOV with a draw threw MAF? the compressed air being released to the atmosphere has been meetered already, no wonder you had tuning issues.
BOV before a blow-threw MAF... is the correct way to run a turbo setup.

Yea, that what i meant, the waste gate. not the blow off valve. sorry for the confusion

FWIW: I ran my TA-49 turbo without a BOV for 4 years on my old GN without any problems. Almost all of the GN guys don't run a BOV(at least when I last owned my car). The sounds of the turbo "sneezing" back into the atmosphere through the MAF/cone filter would scare everyone.
This is definatly a cool project! Reminds me of the LS1/LS2 guys I see around here with rear mounted turbos.

No I am not that dumb, I have done too many boosted projects to screw up that badly  If you read my posts you would understand what the problem was, but there are too many of them to expect that kind of home work. OK so originally I ran the by pass valve just like the vortech setup up was intended on the mustang. THe intake stream went this way: Cone filter, MAF, bypass valve return, breather tube, supercharger, charge pipe, by pass valve exit, idle control motor, then throttle body. The way I had it set up originally the MAF did measure all of the air going into the engine and the by pass return occurred between the MAF and the supercharger input. This is exactly how the vortech was intended on the mustang. Unfortunately what happens is that the extra air produced by the supercharger that is released when you let off the gas is let off through the by pass valve and if there is too much air it will actually blow dirt off of the cone filter. Of course in the process the air excess air blows past the MAF. This is enough of an issue that there is actually adjustments in the pro racer software specifically made to remedy that by using the failed maf table when this occurs. Now the way I have the intake system is in this order: cone filter, breather tube, supercharger, charger tube, by pass valve exit, MAF, idle control motor, throttle body. That way any extra compressed air gets vented to atmosphere and can't blow backwards across the MAF. Doing it this way avoids having to reference the failed maf table during blow off and this of course makes the programming much easier and makes the datalogging easier to interpret since there aren't crazy MAF readings when you let off the gas.

Did he run that # on the stock injectors, or with 42's? I am confused.
Also tell your bud, great car. Comming from the mustang world, and now with the Vic. I already have the itch, and this is right up my alley. So tired of the normal, Vortech, Paxton, Kenne Bell, Whipple crowd.
Had alot of ecxperience building my mustang, so I dont think this would be such a big deal. LOW BUCK STYLE
Did pete build and tune the kit? I have a few questions before I start mine...

Hey Dan
Your car is pretty nice right now all NA and you have done a nice job on the overall package you have...
I would go with an S/C like Drock (or a radical procharger if you wanted to get stupid on us...)... Drock's set up would look very nice under the hood and scoot to boot...
I just think that would be a very nice DD with a ton of guts.... lots of low end...

We don't?? Where have you been? Drock's car is a roots style like those mentioned above and mine is a vortech.
