because V8

You couldn't possibly know anything about that.............

 

Never heard of breaking in a turbo. How so?

The Aerodyne was ( still is) self-lubricating.

Raise the boost a bit and the low end should improve somewhat.

corky

 

Well, one obvious benefit is he doesn't have to do any gymnastics to get ambient temperature intake air, no?

 

Because we don't give trophies for participation here. If you aren't ready for criticism and a thorough questioning of the logic behind your build choices, I strongly advise you to find another forum to post your build on. If you can handle the criticism and justify your logic, you'll do just fine here.

 

To elaborate on what Sav said its basically that bullshit isn't tolerated here. You can't show up and say a rear mounted turbo is the best thing since sliced bread (which you haven't. But I'm making a point) and not back it up with technical reasoning.

Don't take it as hostile, we like cool and innovative things.

I still think the setup is really cool, and am interested in results. The only other rear turbo setup I know of is on a V8 making 600hp+ I believe.

 

MT is just filled loveable jerks. Love you guys.

Op, post up a video of the exhaust. I want to hear how loud it is, I can't imagine it being too dd friendly.

 

Hi Corky, In the beginning with the packed ceramic bearings the turbo does not spin totally freely like ball bearings right out of the gate. After a couple hundred miles the shaft and bearings seat and the turbo spins really freely. I remember the FRS after I'd turn the motor of I could stand there and listen to the turbo slowly wind down. I was shocked how long it took. That's just my experience. I will raise the boost and see how that helps the low end, unless the waste gate is leaking how would that come into play??

 

You are right about both points.

Grease packed ball bearings get better as they wear in. I just installed some sealed wheel bearings in my truck and they were totally stiff. Now they are smooth.

Only way raising boost will help is if the wastegate is getting blown open because of lack of preload.

 

I have external Tial so I'll throw a a little heavier spring in there and check it. I have Christmas week off so I'm going to do some experimenting.

 

This guy does a pretty good test between ceramic bearings and normal alloy bearings. The difference isn't nominal, but then again, neither is the price.

 

so i need to watch a 3:30 video to read like 4 lines of text?

 

The normal mounting location puts the filter right next to the headlight, a high pressure zone that is perfect for taking in cold air. Not sure what gymnastics you speak of.

 

not entirely sure that hor air just off the pavement is better than air sourced from the headlight either... Not that it really matters much.

 

Also, this was the last rear mounted guy we had to deal with:


it made 170rwhp at 15psi. It hit 15psi at redline.





and this jewel when he was still using the AFM:






I'm trying to find the one video where he was randomly at a car show and broke his spolier by trying to sit on it.

 

or this gem that came and went:

This turbo caught on fire or something last I heard, apparently you shouldn't run turbos without any cooling/ventilation.

 

You'd also be curious to know that BEGi developed their NC turbo kit based on a rear mounted turbo for proof of concepts.

 

We've seen a fair number of crappy turbo setups around here. Some of them have been rear-mounted, some haven't.

But to be fair, this Roadstercycle guy seems to have done a pretty good job of it. Wouldn't be my first choice of hardware, but as a former CA resident of 8 years, I appreciate the appeal of the stealth setup.
