Bob
rough welds could come loose and end up in your motor.but he didnt post that pic
(inside weld seam) now did he? that's all i have to say about that.
Bob what's the installed/tuned/dynoed price with polished head unit and D1SC? (I have the diablo already, is there a discount for already owning the handheld you can upload the ATI tune from?)
The Best V8 Stories One Small Block at Time
The STS kits look like a good deal, here is a list of my opinion of them, and why I don't sell them anymore:
1. STS claims that heat is not required to help spool the turbo, that exhaust velocity does the job.
Major retailers of the STS kits sell the kits with exhaust wrap, to help spool the turbo. We have done this at our shop, and it helps quite a bit. It is obvious that the closer to the engine the turbo is mounted, the more efficient it is going to be.
I copied this from the STS website.
"Doesn't heat create the velocity in the exhaust gasses to spool the turbo?
No, heat doesn't create velocity. Heat creates volume. If you look at any of the physics laws for gasses, you will find that pressure and volume and heat are related. PV=NRT is a popular one, The V isn't for velocity, it is for Volume.
The turbine housing is what creates the velocity. The scrolling design that reduces the volume of the exhaust chamber as it scrolls around causes the gasses to have to increase in velocity and pressure to maintain the same flow rate.
Hotter gasses have more volume, thus requiring a higher A/R which in effect means that it starts at say 3" and scrolls down to approximately 1". Lower temperature gasses are denser and have less volume, so they require a lower A/R housing which would start at the same 3" volume, as the turbine housings use standard flanges, and scroll down to say 3/4".
Now if you were to reverse the housings in application, the conventional turbo would spool up extremely quick, at say around 1500 rpm but would cause too much backpressure at higher rpms because the higher volume of gas couldn't squeeze through the 3/4" hole without requiring a lot of pressure to force it through. On the reverse side, the remote mounted turbo with its cooler denser gasses, wouldn't spool up till say around 4000 rpms but once spooled up would make efficient power because it doesn't require hardly any backpressure to push the lower volume of gas through the larger 1" hole."
So I take it the exhaust wrap should not make a difference?
2. You don't want to run catalytic converters with a rear mount turbo. Years ago a guy brought in a Ferrari to us that had a rear mount turbo. One of the catalytic converters internals came apart, as they sometimes do, and parts of it lodged into the turbo, ruining it. I predict that this will be happening to the STS turbo customers.
3. The oil return line is routed into the passenger side oil cap on the STS kits. This line has a habit of coming loose, and spraying oil into the engine compartment. It happened to us, and I have read where it has happened to other people.
These engines already have enough oil returning down through the heads, they don't need more! This is a bad design, and many people are rerouting the oil return line to the oil pan, where it should be in the first place. The problem with running the line to the pan is now you have to drill or punch a hole into the oil pan to run the oil line, unless you remove the oil pan. We recently removed the oil pan on a customer's car, and welded a bung into the pan for the oil return line.
4. The turbo hangs without brackets supporting it, and will sag over time. We add a bracket when we install these kits, I don't link seeing the turbo dangling there.
5. The air filter is in a bad location, as is susceptible to dust, water, dirt, etc. STS offers a cover that goes over the filter, but we found the cover seriously hinders performance. We proved that on our chassis dyno.
6. On the F Body STS kit, a driver side subframe connector cannot be used. STS claims their plumbing that is routed down the driver side does the job of a subframe connector. We find that humorous, at best!
7. The plumbing underneath the car hangs too low in my opinion, and you don't want a lowered car with an STS kit on it.
8. The silicone couplers that are provided with an STS front mount intercooler are thin, and we had two of them blow apart. The intercooler plumbing that was provided with the front mount intercooler option that we ordered for a customer's car was poorly routed, we ended up using our tubing from our front mount kits that we sell.
9. The oil lines sure have a long way to run, from the front to the rear, and back up front. If a leak developed, it could be a quick way to ruin an engine.
10. It would be relatively easy for someone to slide underneath the rear of an STS equipped car, and steal someones turbo.
11. The boost line running back up to the engine from the turbo has silicone couplers at various points along the way, and can blow apart.
12. Any exhaust leaks will diminish the efficiency of a rear mount turbo.
I appreciate the time you took to share what you & i both know to be very true about
said kit. it does have some naging issues that should be addressed by said company.
now, with that being said, what if made the wrongs right?
ie: oil line/fitting bung to pan, wrap hot side, eliminate the shytty worm crap, adjust oil pressure to turbo side,use all t-bolt clamps, fab/make solid mounting attachment point, ...the list is getting pretty long. lol
now, if those things were (and will be) eliminated/corrected would you still feel the remote mounts are a waste of time.? ( i noticed that firechicken install you guys did and it was sick)
your answer won't sway my thinking, as i'm doing the rear mount either way, but i do respect your opinion and knowledge.
again, thanks for your time and understanding in this matter.

'ing this thread? If rear mounts were so great, then why did Mike Murillo change his twin rear mount back to a front mount setup?
Sts is in the same class as the turbo-nator and also the fuel atomizer magnet
got him recognized in the first place...
look, i'm not a track *****, i'm just a guy who wants to be the 1st to install
a turbo on a cadillac...i'm no threat to anyone.
i'm just a pimp with no hoes.

You're a troll.
