Most people consider it the time until you reach full boost. Lag will vary depending on many many things, load and turbo size being the main two. Temp affects it as well. It takes me 300 rpms longer to reach full boost now that the temps here are 110+
I thought part of the reason turbo's were mounted as close to the engine as possible was to reduce lag, and that this reduction in lag was due to increased velocity and higher pressure(caused from higher heat). What I'm asking is what is it about higher ambient temps that causes increase in lag?

Wow what a thread! If anyone cares I love my daily 90 mile commuter 02 STS SS. (Mattism78, I sent you a special PM/email.)

By the way, in first gear my car hits boost at 3,000 RPM. I have a lower rev-limiter programmed into my car so with the clutch pushed in I can bounce off 3500 RPM when I'm staged at the line. Give me 3 seconds and I'll have 5 PSI ready to go waiting for the light to turn. Dropping the clutch at 3,000 with 5 PSI is a pretty good way to reduce your 60'times by the way. No, I don't have good track times, the density altitude today in Salt Lake is about 10,000'

The exhaust gas being hot will cause it to have extra volume. This extra volume then has to fit through the same size hole. When it all can't fit through pressure builds up in the manifold. The sooner you cause this action to happen, the sooner you will see boost.

With the turbo at the back the gas is cooler, hence less volume, but still the same quantity of exhaust molecules, they just aren't as excited as when they came out of the combustion chamber. The solution to this is to use a smaller hole that causes them to build pressure faster.

The hole i'm talking about is the a/r of the turbine housing and the wheel selection.

When it's hotter out the car doesn't make as much power, less power = less exhaust to get the boost building process going. I'm at 2200' and have excruciating day time temps. On a day like today 117 F i'm losing around 70-80 rwhp compared to a 65 F day. When I dynoed my car it was 96 degrees in the shop, my corrected numbers were 507, my uncorrected were 460.

P.S. The turbo does work better when it's up front, but it works pretty good out back too.

He ended up running a decent time down track but didnt boost until well after 60 ft after the 60 ft marker! 3450 isnt gutted...stock carpet, panels, etc. rear seats are removed and alot of lightweight suspension stuff.

come on admit it, that was pretty funny


oh i remember the 408 you were talking about..it had stock ******* heads...please stop before i bitch slap your *** once again. Remember my graph ..peaked at 4k on the dyno an even sooner on the street ya i thought so.

As for me being a keyboard commando..please come meet me...it will be the greatest day of your life. I wait with baited breath you sexy pillsbury muffin.

Water issues will be taken care of shortly. STS is coming out with a filter and shield combo to once and for all remedy the chance of a problem.

On a more serious note, Purevl your numbers are impressive. I haven't seen that many on an STS with those numbers, but I have only been doing some research on the kit for a short amount of time. What exactly does your setup consist of? I have considered maybe purchasing this kit in the future, but I don't plan on stopping at 500rwhp and I need to have a good plan before I start throwing money everywhere. It would also give me hp #s and expenses for this kit to compare to other setups.

Do **** waffles come with syrup?
it was

forged ls6
patriot 6.0l heads
226 cam
sts gt70 with fmic
ati damper
hooker headers
big expensive fuel system..(dont feel like typing it all out)
motron 60's
ls6 intake
ported tb
stock maf
evans waterpump
and the most important part don kinder tuning (slowhawk)
im sure if you search my name you will find the full list somewhere but thats pretty close.

ok now that i've asked and have recieved there are actual answers to why STS are having "shitty" 60's The answer... big turbo...... not enough "excited" molecules (gas) moving into the turbo housing at a high enough volume. There for "spool" times are increased there by reducing the amount of boost avil. during your initial 225 ft or whatever you quoted. Now for the noob to school you... bigger turbo = the the opportunity to produce the greatest power How ever the bigger the turbo the more "lag" you produce...(doesn't work exactly like that but i'll assume your not a complete tard)... So your "buddy" with the STS who has a shitty 60' needs to consider a couple of things.... "brake boosting" or small turbo.. by shrinking it will reduce the amount of gas required to turn it there by reducing lag time.. so for those who have full boost or most of there boost at 3k or 3.2k they are obviously more intellengent that your buddy or your buddy was aiming for something else....

2 all of those more intellegent than myself and V6 please feel free to gently correct me... again i'm a supernoob but it appears i'm not alone.

autos (like the 2 10sec gtos) build boost on the line just like any other turbos...they 60 in the 1.4 1.5 range and at 4000 pounds thats awesome. As for the 6 speeds...any turbo will suck without a two step. V6bird just feels like leaving that out.If a stock car with 300rwhp can 60 1.8 wtf would an sts slow it down? Makes ZERO sense. Like i said hes a dickdolphin

So what's the best stall for us A4 guys to go with to make boost out of the hole?

Best not so much as in brand, but stall speed, and STR?

V6, Please let me formally invite you to visit our track out here in SOCAL, I feel the need to make someone feel a little STUPID. I Have not even had the opportunity to dial my car in but I can tell you I have no fear of your supposed vehicle, I stand behind my work and I am confident that my STOCK LONGBLOCK will teach you a lesson! I simply need about a month to get my trans installed....If I loose to you I will pay for your round trip to sunny and HOT California...In other words leave this thread alone and stop badgering the members here until you PROVE your slower than an STS car!!

I don't even go to the track that often and I know twice i've seen 7000+ DA
Whats funny is that I can run the same ET at 1000 ft DA as I do at 4500 DA....why is that guys? It cant be....i did it the last 2 seasons

V6 bird please STFU and stop wasting bandwidth...I now officially think that some people should have to take a test just to be allowed on this site

Come on guys admit it, the STS works reasonably well for its funny placement. The results both on the dyno and those who have provided track times and vids of the STS on various vehicles show that its a nice kit to make some great power. We are talking street cars, not 200mph outlaw cars. 700rw on a street car is very impressive no matter if its Turbo, SC or N2O or NA....it'll definately get you to the grocery store quicker than stock

Mike you rock, asshammer, twatwaffle...classics buddy classics.

I could have so many sig quotes from what you have posted....... I bet Don does alot of the work because you guys hang out and get drunk and laugh so much......... I say keep it going i was almost crying from laughing so hard.......

My .02 for a DD car that doesnt want to spend to much $$$ and be happy with your new found power STS is a good way to go......... its alot cheaper..... i can tell ya that much ha ah LOL :jest;
