I have had mine for about 2 years. I first thought it was a little low. I had some brackets built that really helped keep it nice a tight and close up to the body of the car. I have not had any problems since. Love my STS kit

yea the clearance issue and running a oil line that far really scares me one of my friends had one on his ta and ripped it off pulling into a gas station
I'm getting 10 psi in less than 2 seconds, filling an oversize pipe and a big fmic.
Currently I have a B&M deep pan on the auto transmission, and it hangs down lower than any part of the turbo setup. (will be going to a deep truck pan instead, won't be quite so low).
The oil line tucks up in the same place as the fuel and brake lines. If it's tucked up right, you won't be yanking it out. The lowest turbo related parts on mine are the pipe under the rear lca, and the pipe under the front lca.

I had a STS kit on my old LT1. I won't ever put an STS kit on a car again. A 2.0l Mitsubishi lags less. And once it did spool, it wasn't even that fast. I got walked by a stock LS1 Corvette.
Well obviously you had something wrong with yours bud... The worlds fastest IRS vette is a sts powered one that runs in the 7's. So maybe instead of bashing the thing as a whole, look to what you had and realize that maybe something was wrong
i have had kit for almost 3 years, i laugh at people who worry about dragging the turbo or yanking an oil line. the kit is only as good as the person installing it. the first kits most people did not do what was needed to help spool the turbo, wrap the exhaust, run manifolds not headers etc... there are enough threads and information on this site especially from Zombie and Longrangue4u.
the kit makes great power , i currently have 500rwhp at 9psi through an A4.
good luck.

And the fastest Top Fuel drag car is in the 4s, with a roots supercharger. Doesn't mean it's good.

There's a lot to upgrade when adding to a stock car. Double springs are highly recommended, hardened pushrods are a must, high volume fuel pump, higher volume injectors, better clutch if it's a manual, (my personal recommendation...a wideband A/F gauge), and so on. Once all is added up the STS is the same cost as a Vortech or Procharger. There are many topics in this forum on what exactly is needed.
To answer ground clearance.....my driver side header collector is the lowest part of the car. That's with the DynaTech SupermaXX headers (which tuck up pretty decent). The FMIC adds significant front ground clearance over the non-intercooled stock STS pipe.
Hope that helps ya' a bit.
You were wrong in BOTH of your posts in this thread. Keep trying.
There are ways to keep it higher in the rear. I've banged the long pipe that runs up the driver's side once on a big speed bump. However, I was going too fast and it didn't do anything.
The pressurization of the pipes isn't a big deal...they've proved it works. BTW, if you do want the long pipe that runs up the driver's side, I have one for sale
. I originally bought my kit for a non-vert only to find the underside of the cars are different

Anyway, yeh. You'll need injectors at the very minimum and probably a fuel pump, the stock one will be good for ~400-450 hp but not much more. I'd also look at an FMIC, probably would have saved me a motor. TRT makes a good one , I've got one installed on my car. Having a turbo car is a blast, and the pipes dragging isn't that bad, with the FMIC it gets alot better.
A friend of mine put a 10psi sts kit on his 02 SS camaro and it stood out like a sore thumb and someone saw it and stole his whole car. Seeing that pretty turbo hanging under the car is very tempting to steal. Plus i put a good set of heads and a good cam on my car and it was just as fast if not faster and it was alot cheaper than a sts kit.

What's with the stupid sign pointing to my post? He was wrong in both of his posts in this thread. Its BEYOND proven a properly installed rear mount can make endless power and spool plenty fast.....and he somehow made the inference that a roots superchared top fuel car isn't a good set-up. He lost me there.
Roots superchargers are simply amazing. That's why every Cobra owner's 3rd mod is replacing it.

So properly installed means redoing the entire kit? It should come out of the box "proper," not I have to spend $1000 to get it to spool decent. And FWIW, my exhaust was wrapped. The lag still sucked.

If you have stock manifolds (wrapped) and a COMPLETELY wrapped hot-side, and STILL had lag issues, then you must have accidentally installed the kit on your 3.4l Fiero. I have a friend with a rear mount t76gts (kinda big for a rearmount), 346ci, wrapped LONGTUBES, and a wrapped hotside, and he sees 15lbs by 3800rpms.
And roots super-chargers do suck. In fact, my friend (and fabricator) just did some tuning on his cobra. It only made 507hp/479ft to the tires on Whipple's own dyno. He has a cold air intake, cut-outs, and ported STOCK EATON blower. What a turd. 3 mods and hello bottom 11s.....wait, he already went 11.60 before he ported the blower.
It is a shame that some members might read your posts and actually think there is truth to them.
