STS Dyno numbers

Cruizing on the turbobuick board i found this..

Well first things first, finally someone posted IAT's, and holy cow 160 deg with only 12-13 psi of boost, ouch. Also I see a good bit of lag their especially for such a small turbo like the GT35.

Jose

I saw on another board where he said that his IATs were exactly the same 160* with or without the meth injection. I also remember a while back when I was doing some tuning with my IAT sensor unplugged it stayed at 160*. Hrmmm, could there be some sort of relation???

There is no way that the IATs stayed the same with or without the meth injection.

Well depends where he is spraying the meth. IAT will not record anything after the sensor.


Jose

If the sensor is pegged at 160, then honestly, what temp could the air inlet actually be? It's nice to see more and more coming out about the STS kit, and It'd be neat to see dyno graph with IAT's vs RPM as well without meth. I'm wondering about efficiency- and is it just me or is a GT35 a little small for a 5.3L? If that's the case then the IAT's might be even higher... Unless I've got something wrong.

Who wants to bake a cake in the intake manifold? :D

Decent numbers though, I bet that thing would be kinda fun to drive.

Jose- any updates on my ptk parts?

Goeff, I call this morning and its on their production board, so now its the waiting game. Which is the part that sucks the most....lol

Heh, I was asuming that the dude wasnt dumb enough to brag about IAT #s with and w/o meth while spraying it after the sensor... But, you're right that could be the reason theyre the same.

*dammit, im returning this meth injection crap...its not lowering my air temps one bit...* hehehe


Besides, does the IAT sensor actually peg out at 160*? My air temps have never gotten that high to find out :D

His dyno started at 4,000rpm and it didn't look like there was much lag to me. He had a 3k yank in the car.. with a turbo or not he probally woudln't be able to start the pull any sooner.

Anyone used to high stalls and being on the dyno will let you know that, with my 2800 stall I couldn't start a pull less than 3900 or so or it would downshift.


Also, it said 160 Before the methonol... not after.. who knows what the IAT's truely are.. he didn't share them.

I don't understand why they run the turbo so far back on the trucks. There's plenty of room to put it up front under the cab.

I'll just quote myself:

"STS, the Powerdyne of turbochargers."

LOL :D


I actually used that once at another board. People got a good laugh out of it, even one powerdyne owner :D

I was refering to a post on a different board where he said they were the same with and w/o the meth.

besides....430hp on a v8 w/13#s of boost == LAAAME

:rolleyes: :rolleyes:

Dont be H8Tn on the STS lifestyle YO!!

I don't know where youre coming from. How much stock power do
you think a 5.3L truck motor makes? Its not an LS1 or An LT1.
It probably makes maybe between 230 to 250, so if he's making 430 I'd say thats not a bad gain @ 13 PSI.
This board is unbelievable, There's more bitchin going on here,
It's like a bloody witchunt. If the Guy is happy with his numbers
thats great, Cause if he can pick-up 150 to 200 HP with theres
diddly wrong with that.

Most stock 5.3's dyno in about 225-235rwhp, depending on dyno, car ect. So 200rwhp increase isn't that bad at all...not exactly the best kit out there, but the curve looks nice. Also...the graph looks like an UNLOCKED convertor to me...which could be costing a good amount of RWHP....since it is a 3000+ vert. I bet its fun to drive!

BTW...Im making a kit soon for the 99+ ls1 trucks...tuner style. Just the hot parts, you supply your own fuel management,intercooler, ect.

Chris

My IAT's suck too, anywhere from 160 to 180 deg with 10 to 12 psi depending on the shift, Also only 420 rwhp. but can only run 16 deg timing or get knock. Thats a S-trim

Dont forget though... that 5.3 motor in his truck is not stock. It has a cam that, judging by the specs, was picked specifically for a turbo application.

Jeepoo,
You just go on with your 400hp STS LS1 turbo. Just dont expect to impress anyone or win any races.. :rolleyes: :rolleyes:

At that psi without a cooler you will see those temps. We have been tuning our 2000 SS STS with the sequential methanol system and killed the intake temps on high boost, down below 120 degrees with a small jet on 10 psi. The car is running great and numbers will be up soon. And we have won races with our cars.

I think you missed my prior posts. I am not building a race car, but looking for a few extra horse power without adding a whole pile of gadgets and tons of heat to my engine compartment. Also something I can remove without too much trouble if I have a warranty issue.
As far as winning races and trying to impress people, I don't need to do that.
I've got a roomful of trophys from 35 years of drag racing. My wife keeps threatening to throw them out.
I also don't like the idea of running around with a bottle in my trunk, so the STS solution is perfect.
On top of that I don't think a stock LS1 would like much over 400 HP for an extended period of time, especially since the CR is already on the high side for this type of application.
And as you well know since it seems all the car manufacturers are back into the HP wars, I'm just trying to stay near the front of the pack.
