sts turbo questions

[aquickfive0]

i just ordereded a sts turbo system i have a 2002 trans am ws-6 auto
completely stock, what should i expect to run in the 1/4 at 5psi and or if i bump it to 8psi for track only

[FastPontiac]

I just put an STS turbo Kit on my stock 01 WS6 TA and had it tuned last week. It showed 435 hp and 441 ft-lbs at at the rear wheels. I can email someone the dyno sheet if they can post it somewhere that everyone can get to. I asked what a stock LS1 f-body does on his dyno and he said 315 to 325 with a cat back. I will take it to the drag strip when it opens in April. My only other mods are a racetronix fuel pump and 42 lb injectors. My car sounds quieter than with my Loudmouth II exhaust at Idle and light throttle. But when you step on it it makes a big woooooosh sound. My friends girlfriend had to plug her ears as I went by her window in his vette. She said it was too loud and made a high pitched sound, but it sounds cool from my seat. And I liked seeing his car in my rearview mirror.

Send the dyno pic to me, I will post it for you.

Thanks for the help.

[aquickfive0]

any1 done the 1/4 mile yet?

[BrandonDrecksage]

its varies...there is no...if I put this on ym car..i'll run this....you could be in the 13s...to high11s depending on traction...track conditions, tune, elevation...ect. have you run your car stock?

[aquickfive0]

ya, i wasnt asking what it should run , i wana know if any1 rading this has set-up on a basicaly stock ls1 and what they ran. i run 13.6 stock
im trying to see who has set-up adn what they run adn what mods were done to theres

[clemsondave]

Wow, I am having a flashback to 2nd grade spelling and grammar in this thread. :shrug:

[02IKND]

I have a 02 WS6 with a STS turbo kit. I have a racetronix fuel pump, 42# injectors, TAIL wastegate and BOV, NGK T6 iridium plugs w/ .028 gap, and spec stage 3 clutch. I ran a 12.9 @ 116mph on street tires at 5 psi. So far, I've run a 12.5 @ 120 mph on street tires at 7 psi. I'm going back march 11th with DR's or slicks and with my ignition problem fixed to run a better time. My car dynoed 413 hp at 5psi and 467 hp 508 tq at 7 psi.

Here is my dyno sheet.

[aquickfive0]

is that completely stock?
have you run the 1/4 mile yet with the set-up?

[FastPontiac]

I bought a Tekmate OBDII scan tool off ebay a few weeks ago. It hooks up to a laptop and is supposed to be able to measure your 1/4 mile time. I will try to go make a run with it if the weather cooperates in the next few days. It snowed here a couple days ago but I think it is supposed to be nice now. My car did a 13.022 @ 108.57 stock with a SLP Loudmouth II catback exhaust at the drag strip last summer. I launched it at about 3000 and shifted hard. I want to get low 12s or high 11s with this kit. I'm not sure if I will have the traction with street tires.

[02IKND]

Check my post right before my dyno numbers.:thumbup:

[FastPontiac]

I ran a 12.48 @ 116 mph according to the Tekmate OBDII scan tool. It is 35 deg here so I started off easy and didn't shift very hard so that I wouldn't spin the tires and throw off the results. I expect to get a better time at the track.

A small muffler ont the wastegate should quiet you down quite a bit:notworthy:
I'm planning on buying the kit soon, just havr to figure out for what car:thinkin:

[fredl11]

have the STS system but I am running the Incon TT @ 5lbs boost on a stock block. Right after install we took car to the track and with street tires and no hole shot we went 12.31 @ 121 mph. Have yet to go back. Driving Turbo cars is a trip!! Love hearing the turbos go wissh!!!

:drivin:

[aquickfive0]

hmmmmmm wishing on a low low 12 or high 11 would really love to get sum how without spending alot more $$$

what kind of muffler are you talking about?:dunno:

[NYSS Guy]

I ran a 12.2 @ 116 at 6psi. That was on a stock motor, 42# injectors, fuel pump, and a 2 step (it's a 6 speed). And the tune was still a little off. With an optimized tune, the car would have broken into the 11's at 6 psi.

[camaro_ss_97_]

question. i have a 97 ss with the lt1 and was thinking of either a supercharger or a sts turbo set up. someone told me that i would have to build my bottom end to handle a turbo???? i have 111000 miles on the car. is that to many for either charger?

[NYSS Guy]

Not necessarily, but save some money, cause it probably wouldn't last long. Do a compression test to make sure you have good compression first. Personally, I think your mileage is a little high to start boosting it. Good luck.

If you stay consertive on the boost 3-5 psi it will survive. I have found users of the STS setup on 5.3l chev pickup go well over 100k miles.

[FireFox05]

How long do you expect the rear would last with the STS at around 5 PSI?

[44newman]

Rear what? End. Depends on how much you abuse things. Probably last 4 ever if you drove like my grandma. LOL

[onelife]

02IKND,
what was your ignition problem?

[RyansREDcamaroSS]

Do you guys recomend the turbo? I talked to STS, and I was planning on the bigger turbo, methanol injection, AFR heads, cam, fast intake, built tranny with a stall, 12 bolt moser, should I be pretty quick?

[onelife]

Before you bolt on a larger turbo, do all your mods first, then run it with your existing turbo.
If your standard turbo begins to die out at top end, then go to a larger turbo.

[koolaid_kid]

I can't agree with onelife; if you want the larger turbo (I did) get it first.
If you blow your engine, rebuild or replace it.
Wshhhh.

[dkt-performance]

i ran 12.7 on my sts kit. 5 psi. all stock 98 ta A4. i had ls6 intake and tranny tune

[Schantin]

:werd: I just finished installing my STS kit w/ -67 turbo. Car's quite entertaining to drive right now. It'll be even more fun once I get all the tuning bugs worked out. It's running stupid pig-rich at WOT and stumbling a bit from fuel overload. I added 42 # injectors and the Racetronix 255lph fuel kit to my car prior to install. I also have a TR224 cam.....so it'll be interesting to see what this puppy puts out once all the fuel tables are set. Hoping for 11's on only 5PSI. :)

[02IKND]

02IKND,

Haven't figured it out yet. Plugs and wires are replaced, coil packs are good. Doing leakdown and compression tests today. I'm thinkin that I have a bad piston. :( Gonna make that baby into a beast if I have to rebuild it.

You should be well into the 11's with that setup. I ran 12.2 at 6 psi, with an otherwise stock motor. And the tune wasn't done yet. I was running too rich, and too little timing. Good luck with it.

[FastPontiac]

The track finally opened up today. The temperature outside was about 50 degrees and very humid. I had lots of traction problems :drivin:, but finally restrained myself so the car could hook. My best run was a 12.454 @ 116.73 MPH. On one run I accidentally shifted from 2nd to 5th and I smoked the clutch. Time for some tire, clutch, drive train, and suspension upgrades.

[ScrapMaker]

Is this the rear-mounted STS turbo, or the under-hood?

do you all think that this is a great value for a turbo?

[trtturbo]

yes

[FastPontiac]

It's the STS rear mounted kit.

[02IKND]

02IKND,
what was your ignition problem?
FINALLY figured it out. Very low compression. I ran the car too hard and the rings and pistons are bad. I'm pulling the motor this weekend. Guess it's an excuse to put a stronger motor in it.

[ScrapMaker]

so what would a completely stock car, with stock injectors and no tune what-so-ever run with the sts @ 5psi? I'm guessing it would be less than 400hp

[NYSS Guy]

Not a good idea to run any FI without a tune. But, with a mail order tune, at 8psi, I was around 425rwhp. I had it dyno tuned, same exact setup, and hit 475 rwhp at 8 psi. Once the tune was decent, I turned it down to 6 psi, and was around 420 rwhp.

That was all on a stock LS1.

[ScrapMaker]

when you say 'tune' are you speaking of a separate computer module... a programmer? does this rewrite the onboard computer, or do you leave it plugged in at all times? Most of the people I know with tuners/programmers, have them mounted somewhere on the dash/under the dash, have an LCD readout, and you can switch between programs and whatnot... is this similar?

[y2konyxss]

you can get the computer tuned and then its on the computer in the car and you dont require any programmers afterwards but lots of people monitor their car with a tunner device or application on a pc and are able to tune on the fly if they have these applications.

but most of this stuff is readouts of what is happening after you flash your computer with the appropriate flash for your engines specs and boost PSI.

kinda a short summary

the car will run very poorly without a programming as well as risk your engine if the cars timing is to far advanced and the fuel mixture is too lean.

KABOOM

[ScrapMaker]

okay... that is sorta like when you re-flash the chip in the older cars... I had heard before you could re-program stuff on the fly with the ALDL port... and not pull the chip on ODB-II cars...

my friend has a 2005 STI and he had a box where he can hook a laptop up, or the box itself has like 5 preset program modes... he just picks one depending on the situation...

so a "mail order tune" is, I'm guessing, the actual tuner module? or you send off your prom to be reprogrammed?

some cars you have to hookup another module to allow for tunning, but for the ls1's its a tune right on the ECU, so you can send ur ecu off to get reflashed with a performance tune.

with a handheld like a diablo or even software for a laptop like Hptunners you can just flash the ECU whenever you want. and if you take off the parts you can flash back to stock.

[02IKND]

so what would a completely stock car, with stock injectors and no tune what-so-ever run with the sts @ 5psi? I'm guessing it would be less than 400hp
My guess is yes it would be under 400. Mine at 5psi with a tune and the injectors and fuel pump dynoed at 413.

[ScrapMaker]

I wonder what you could get with new cam, intake, headers, heads, and full exhaust(catless) AND the 5-7psi sts?

I'm guessing that would push the limits of the LS1 lower-end... and maybe even the block itself...

[aquickfive0]

sounds bad as fuck, love when the blow off valve kicks in

need to get it dyno tuned now any1 know of anywhere good in central florida and about how much it costs?

the oil pump in rear is loud, i can hear in the car, is that normal?

[ScrapMaker]

the sts kit comes with an additional oil pump, or did you mean fuel pump?

[aquickfive0]

whats sum good tuing places i can order from, whats usual costs, looks like $425 and up for most

anything cheaper

[y2konyxss]

the sts kit comes with an additional oil pump, or did you mean fuel pump?

the sts oil pump is loud for the first little bit from what i read.

mine i to go on my car in 2 weeks

[ScrapMaker]

is that oil pump for a separate oil system for the turbo? I read it's not using the car's main oil supply...

[y2konyxss]

the STS uses your engine oil,

there is a line from your engine at the oil filter then runs into the turbo the back to a after marked oil pump which is included with the KIT then it dumps back into your oil cap.

very simple system but is effective.

[99TAWS6]

The oil pump is pretty simple but one more thing that can possibly go wrong.Although sts has warning lights for it which is a good idea.You need the pump since the setup is at the back and think incon also used a scavenger pump on their twin setup.

My ordered setup is front mount and has no oil pump.
The sts are very neat and work well.Had ride in one lt1 sts car and it was impressive even at 5psi and bone stock.Kicked my 96 z28 verts ass pretty easily!

There are some big power very fast sts cars on ls1tech. I have gotten into a few arguements over the sts idea and theory but I can assure you in practice it works and works well.
I look forward to a ride in y2ks car since he lives in my town and we know each other.
he is supposedly getting it finished this weekend.He is running 42s and I sold him my single racetronix pump setup since going to twin pumps in my car.

I planned on either running with some mods on stock engine this year and then build a forged stroked up iron block over the winter. Currently have waiting for install fast 90 intake ,getting NW 90 tb and have lingenfelter gt 7 turbo cam. Was thinking some lq9 patriot heads to lower compression a bit.
Then next year get forged stroker crank, rods and pistons and build a nice 402 or something.Going with 65 pound injectors for now and dual inline stainless line fuel setup with bigger rails.

Anyway as said the sts is a nice option. Enjoy it.I think it sounds great just the way it comes. But then again I love turbo cars.

[koolaid_kid]

the oil pump in rear is loud, i can hear in the car, is that normal?
Unfortunately, yes.
It is mounted behind the rear seat on the outside, and the vibrations reverberate in the body.
It does have 2 speeds, and starts in high speed. Once it warms up, it should shift to the lower speed and get somewhat quieter. But yes, it is an issue (at least to me).
Other than the noise, I have liked mine.

[y2konyxss]

how long does it take to warm up?

i never heard mine kick into low gear.

its always loud as hell

[aquickfive0]

mine loud as hell

i wana find a way to make it quieter

i dont wana hear it inside car

[ScrapMaker]

is there any way to replace the pump with a quieter version? or maybe the best solution is just to sound-dampen that area

[koolaid_kid]

I agree with everyone, and went round and round with STS last year on this issue.
1) It is possible to put a second layer of vibration dampening. It currently has rubber bushings; one could possibly put a second vibration plate in place.
2) It could be wrapped, but a cooling solution (i.e. fan) would have to be used.
3) Another brand (such as the Mocal) could be used. It has a cooling fan installed, and could possibly be insulated.

I have the same questions/issues, but I have not yet addressed any of them except for thinking about solutions. Others have told me that theirs are quiet, but I do not think that mine is. It sounds like you also think the same.

As far as how long it takes to run quieter, I usually run around the block and it is less loud (not the same as quiet, to be sure). I was quoting from the STS Instruction Manual. Look under the Troubleshooting Guide section, "Oil pump is noisy" section. It also says to check pressure switch continuity, secondary relay continuity. But does not say how to do so.

[y2konyxss]

Thats very good to know
i have about 20km on the car since i installed mine so i hope it gets a bit quieter. but if not i will see what i can do to fix the problem.

I am intrested to see how the testing of the pump works.

Either way i have a question that someone might be able to answer.

I have the STS and i got the TIAL BOV. But i am unsure where the BOV vaccum source is.

where do i hook that up. and does anyone have a picture or can tell me exactly where would be appreciated.

Thanks

[aquickfive0]

i did nine to vacuum hose next to the brake booster adn master cylinder

[koolaid_kid]

20km=12.5 miles. Probably not far enough. I would expect around 500 miles=800km should do the trick.
Being an auto, I don't need a BOV, but I have heard that the brake booster is a good source. Just put in a "t".
