Rear Mount Turbo

My buddy showed me a little about this subject. So apparently people are taking turboes and mounting them in the back of their vehicles with an oil pump and a bit of charge piping. I was thinking, what if we did that here. He wouldn't need any intercooler, and I was thinking we could put the MAF after the turbo somewhere or run speed density. We would have to build a shield for the filter and everything. We could run about 4 pounds on that setup it seems but with a high compression built motor it seems like it would be great. I know someone is gonna say "Why wouldn't you just put on a supercharger then?", well because it can cost less. For example, you can put on two turbos and it we could push 4 pounds on both. We could put a smaller turbo in front of a bigger one and use it to assist it. This could be quite laggy but I bet with the right tuning and right built it could be nice. What do you think?

turbo swap and run 4psi?

you'll still need an intercooler. why would you switch to speed density..

I believe I am in the L61 thread. I wasn't talking about swapping. No, the intercooler would NOT be needed if the air is flowing all the way from the back and only on 4 pounds. Why would you run speed denisty?!?!?!?! Because it is all around better, that's why.

yes you are in the l61 area. idk what that has to do with lol. i use the term swap loosely. it doesn't come on the car, so i call it a swap. but still why 4lbs? totally pointless. turn it up. sure at 4psi you aren't going to need an intercooler. but again, 4psi??

Rear mount turbos are stupid and people who do them are morons who think illogically. Think of the lag from the excessive front mount piping. Moving on. 4 PSI is retarded. You might as well stay Naturally Aspirated for that matter. And to think of 4 PSI on a twin turbo set-up is even more dumb. Maybe you should look into learning more about vehicles with forced induction before you decide to waste money ding something like this. You're better off buying a turbo kit from an 08+ SS and running low boost until you melt your pistons.

And to the guy who asked why the OP wants to add speed density; Speed Density is SO much better than MAF. Eliminating MAF helps tremendously when running higher boost levels. It's a little harder to tune, but in the end, it's worth it. The only downside of Speed Density is if you live in an environment that the weather doesn't stay remotely close to the same climate all year round.

I wasn't going to buy as kit like this. I was merely wondering what everyone else thought of it. If you run it on 4 PSI it wouldn't need an intercooler, why does no one understand that. This would be less expensive, buy a turbo, oil pump, and some piping. That's really not that bad. Your getting pissed about what could be a good idea with the right built and tune. I am not stupid and know a good amount about forced induction. I wasn't wasting my money and I wasn't buying this. I have looked into the 08+ SS kit. I am not going to buy just a kit. I am planning on going racecar later on. Right now I am saving my money for that time period. For someone who doesn't want to do anything too amped. Something that someone might wanna add a little but not a lot, or maybe someone wants to build something or they might have already have and want a little more and that is a possibility too.

we're not getting mad. we're just saying rear mount is not the way to go. and going turbo on 4psi is totally worthless.

I'm not mad. You just have no idea of what you're talking about. It's a horrible idea and not running an intercooler of some sort is just as dumb. 4 PSI is nothing. You will come to find it is just as much of a waste to add 4 PSI as it is those headers you installed. You will barely benefit from 4 PSI. Not to mention, with 4 PSI showing no power, you're willing to create more lag with a rear mount set-up? If you knew enough about forced induction, you'd know these things. The only vehicles that will result from a rear turbo setup is a vehicle with it's engine in the rear. PERIOD.

i wouldn't go so far as to say that scoopin. there are plenty of rear mount kits making great power and laying down the ETs to match. but they are done correctly. with the right sized turbo, proper cooling, and way more than 4psi. which is not what this person is wanting to do. which is why it's not worth it for him. but rear mount setups do work.

Point is that I do know what I am talking about when it comes to forced induction. 4 PSI was just am example. With a rear mount on ONLY 4 pounds, you wouldn't need an intercooler. If you wanted more than go for it. No where did I say I was fitting this up. I was just saying. How many times do i have to say this. Honestly, you people who THINK you know things really need to learn something. I was putting out examples. You can't understand that because you don't know.

4 PSI is a horrible example to use. I've been building in the Chevrolet platform for years and yes, this includes 4 cylinders. I'm not new to this. You are creating a thread about opinions on a rear-mount set-up, but claiming we don't know anything?

God only knows if I brought you in for an interview, I'd hope you could explain why meth injection provides more power. Or why you need bigger injectors for E85.

There is a reason why i am saying a bunch of you don't understand. It is because you don't fully understand this setup. Really? You're seriously trying to tell me that I don't know anything and your not fully understanding. I love hypocrites.
