bunkaccord, the intro

He's probably not coming back. Our last interaction was regarding a bad experience he had on the Facebook group, and he says he's no longer interested in being a part of this community.

I'm in for photos and videos! Would you mind taking a video of idle outside the car, and a few throttle stomps from outside the car (or maybe a run at a nearby strip )?

I'm interested to know how the bottom end is holding up under 10psi. How many miles were on that F23 when you put the block in?

[Qiko]

Wow very creative, any more photos? safe to drive in the rain? Any videos?

[cb7 calling]

Wow.This is the first rear mount turbo picture I have ever seen and its causing me to think creatively, thats awsome. All kinds of benifit to rear mount turbo I have never considered. Aside from theft and deer carcassas rear is probly better than in the engine bay.
I would guess a porche muffler is where you would start but I personally would leave it mufflerless. You will only restrict flow. I would also consider the pre compressor turbulance of a resonator. A biiiig turbo should muffle the sound a little more though.

My jaw just walked away. Too cool.

elcome to the forum man!! this is sick!!!! My dream is having my car turbo but I do NOT want to eliminate my a/c!! this must be fun to drive!! enjoy and keep up the good work!!!

[deevergote]

I'd imagine up to 300whp would be doable without any significant sacrifices.

And yeah, I suppose you're right. Looking at the diameter of that pipe, I don't imagine a muffler would do anything good. It'd likely cause a major restriction, if you could manage to get one on at all.

Thanks again for the welcome. Correct, the pump is only used to return the oil to the engine (valve cover). The oil feed to the turbo is just like a normal setup, except the feed line is about 11 feet long vs. 3 feet. I don't have any room post turbo for a muffler. I plan on adding a long resonator at the center of the car to bring noise down even more. I've also thought about doing a pulse chamber system, but that will require a lot of trial and error to make functional. A pulse chamber will effectively cancel out resonate frequencies, but size, length, placement will dictate the rpm range where it will have the effect. I won't go that route unless the center resonator alone doesn't get it to the sound level/tone I'm after. I also want to add, that this setup was really done just to have something fun to tinker with. Though it does have some unique advantages, I'll never attempt to sell anyone on the idea that a remote system is "better" than a traditional. Currently, I estimate that I'm at approx 215-235 hp. With the next wave of changes, I don't see 300 being out of the question.

Welcome and congrats on the rear mount turbo!

[deevergote]

Life deev said, the main benefit is space. It's nice having just the engine under the hood, then the turbo being it's own thing in the rear. If I ever want to swap the turbo, it would take about 15 minutes. The oil pump is just for sending oil back to the engine. The engines has enough oil pressure to feed the turbo, but since it can't gravity drain like normal, the scavenging pump pushes the return oil back to the valve cover. Loudness level, it's pretty tame. Definitely louder than stock, but a lot quieter than most. Lots of turbo whistle at any amount of throttle and any rpm

That's awesome. I wonder if a small muffler tacked onto the end there would make it near-stock... and perhaps even hide the turbo.

So the oil pump is a secondary pump just for the turbo? Not a replacement for the engine's pump? Sounds simple enough.

Nice.

I'd think the only real benefit would be to avoid the hassle of cramming everything into the relatively cramped engine bay. Spool time might become an issue once things go larger, but it may not really be a big deal.

What's the benefit to using the STS pump? Higher pressure to be able to pump oil all the way to the back of the car?

Also, how loud is it with the turbo in place of a muffler?

[CyborgGT]

That's cool, welcome to the club! Is there a benefit to having a remote turbo aside from the sleeper thing? I'm not really into turbocharging, so my knowledge there is lacking. Looks like if anything you would need to run the same turbine harder compared to a more traditional header-mount, but again call me John Snow.

[bunkaccord]

Thanks guys, never know the reaction it's going to get. No intercooler so far, just the 10 feet of aluminum pipe. I really studied the sts kits, along with lots of custom one off setups. I'm using an STS oil pump on mine. They actually refused to sell me one for my project, I got mine used. I was worried about spool time, so I went really conservative with exhaust and turbo sizing. To the point that I now want to go bigger on everything. To give you an idea, I can get full boost at 2,800 rpm in 5th gear. Even with tall f22 gearing, there's no need to downshift to pass.
