Nice numbers, what are your plans for the car and how far are you going to take it?
If I remember right, Rick up at STS and some other LT1 owner have 10sec cars.

congrats,

allen

Thanks for the insight! I don't want to detract from the main topic, but that is kind of what I am wrestling w/--a turbo, or a big head/cam setup, but I want to be happy w/ the way it drives for the next few years. I might have to look into this kit, just wonder if someone could fab up the STS to my CME setup.

Hey Angie thanks for the input! I have two questions for the STS kit though. How does the cold side piping affect ground clearance and does it stand in the way or cause problems for sub frame connectors?

The ground clearance on the kit is slightly lower than my y-pipe for my TR long tubes. The lowest parts of the tubing are located near the tires, so that helps with clearing things. The main pipe for the kit runs down where a driver's side subframe connector would normally sit. It would be impossible to run a subframe on the driver's side of the car. We did one other thing to the car today...we removed the LS1 radiator shroud (and air filter tray) and installed an LT1 radiator shroud. It makes for a much nicer looking engine compartment now I'll shoot some photos tomorrow.

You could custom bend the pipes to give you clearance for sub frame connecters if you wanted.

Default BMR Radiator Shroud

FYI... BMR makes a beautiful polished radiator shroud for the LS1s. We've installed several of them and they look great!

Those are stock trap speeds for any stick LS1 car. My stick A4 car did 104 and 108 after a couple of mods and my horsepower isn't that high.

I'm not sure of the exact weight of the car, but it's definitely what I'd call heavy roll up windows, no cruise, no power....but really no other weight reduction mods.... it's just like it came from the factory.

According to STS the inlet pipe and mounting apparatus acts just like a sfc on the driver side, so it's not an issue.

Would be nice if someone would post pictures with a sfc removed. I assume they mean the BMR sfc type which don't tie together like slp sfc's

So any opinions on what kind of power the STS would make on a dropin LS6 at say around 8 lbs of boost (GM Direct sells a new LS6 for just a bit over $5K)?

In the test on a stock '02 Camaro M6 in the fall 2004 issue of the magazine "Camaro Performers" pgs 35-38 it made 463hp/511 torque at 7psi (with methanol assist).

Wow...and it's driveable compared to my motor shaking, hard to tune 224/228 h/c package which just barely makes 385 rwhp on a good day (A4 unlocked).

With an additional expense of injectors and bigger pump ($600 - $700), 8 to 10 psi might approach 500 rwhp (STS says you can switch the boost up to 12 psi).

I am sure that's what Thunder has planned next for Angie. Is that the next test Angie?

If that's works you will be hearing from me to make an order.

Hey dlandsvZ28, I can give you some feedback on the car you're talking about.
STS (Rick) and I met out there to install and tune up that camaro. It was awesome to drive and very streetable compared to a heavy head / cam car.
Driveability and response were awesome. There really wasn't a problem with lag or lack of power. Compared to the stock numbers, it's incredible how much power the turbo kit put out. Exact boost was 7.5psi and there was still more. This was a salesman car and I had to make the tune very conservative. Many ppl will be driving this car and who knows what kind of gas or conditions it will be put through.
It would easily spin the tires at the top of second and one time I got it to break them loose on the highway by spooling it up and taking off in third about 55mph, not much but enough to notice if you were a passing car.
For those looking for a true bolt on kit with no cutting up the engine compartment and rerouting lines and relocating brackets, this is a very nice setup.

btw, I'm the big, ugly guy changing the spark plugs out, hahaha, at least in the popular hot rodding magazine.

later,

allen

Cool. Hopefully I'll be running the the Red car as well if we can get a few things finished up today.

A stock 4L60E with 100K miles doesn't like 550+ hp.

The tranny is slipping a bit but we have a beefed up one being done now. Also at the track with sticky tires and a dead hook the kit shows some turbo lag. The 60' dropped from a 1.83 to a 2.2. The best pass of the night was a 12.55 @ 116.8. The MPH show a decent gain for a slipping tranny. A vig converter is also in the work so we can build a little boost off the line.

The kit is on the street but need a little help for good track times.

More to come........................

I like this kit, but I think it's flaw is evident. It's a great kit if you run from a roll, hot exhaust is plentiful to spool up the turbo. But from a dig the lag is oviously tremendous. Until the turbo spools up you have alot of back pressure. Another thing I noticed in the dyno graph is that peak torque RPM increased, that is a little strange for a turbo. Most turbos will give a lower torque peak RPM rather than a higher one. It seems max boost isn't reached until around 5000 rpm or so. That indicates slow spool up due to the exhaust gases cooling off in the pipes before reaching the turbo. A 2 3/4 - 3 inch exhaust pipe coupled with cool exhaust temp feeding the turbo leads to lag. There's a reason why turbos are installed under the hood and close to the exhaust manifolds.

I'm gonna wait a bit and see what happens before I consider this kit further.
