Boost at WOT? (noob style)

[greenmachine97]

Ok, this is my first official newbie question. When you guys are talking about how much boost you are running, is that given amount the amount you are running at WOT?
cause when i get on it in 3rd, the boost will shoot to 12psi very quikly, then when i put it all the way down to the floor(WOT), the boost starts going up to like 16psi and stays there steady.
so am i running 16psi? or 12psi?
thanks in advance for the help, and i apologize for the dumb question. cause i rarely ever just "stand-on-it" , i just punch it a bit and that amount of gas usually satisfies me. i have only gone straight WOT a handful of times. is that normal for you guys too? or am i just a panzi and baby my car?

 

[Coldandafraid]

Pansy!!

And... its at WOT, so you are running 16 psi.

 

[Lunch_Box]

Yes it is at WOT. Boost in you first gear might not get to what you have it set at though.

Well, i cant boost in 1st to hard. because i dont have the pleasure of having 4 wheels powering the car.:laugh: just 2 Yeah, fine i'm a pansy, but i am a pansy who cant afford gas or parts to run around WOT all the time Thanks for teh help!
How hard do you guys run your cars anyway(how often do you go WOT)? (i baby mine, i go WOT like maybe once a week if that).
but i figure, if i dont need it why do it. the cops around here dont like us import kids very much. and i cant get anymore tickets, or i might not have a liscence afterwords

i probably go wot every day.
but wot isnt necessairly a bad thing for the car.

In all actuality you are only spinning 1 tire. I feel you on that aspect. But as I have stated before. You along with your boost controller are the best means to keep you on the pavement without breaking loose. Learn your car and you will enjoy it more than you already do.


You are boosting 16psi at WOT.


And as xcelr8n said....

but wot isnt necessairly a bad thing for the car.

You have to learn and read what your car can tell you. Tune it and run it like you want too.

i would like to, but for now i have no fuel mods and no datalogger, so i am not real sure of how good she is actually running. i dont want to think she is running fine, then break something because of a false sense of security. when i get my logger or dsmlink i will have much more confidence (or maybe not ) in the car, and then i wont be afraid to go WOT all the time. thanks for the help, and by the way midnight, you have a great looking car! do you have any time slips for the turbo? i am interested in how fast she really is!

ya ive had the car logged, and everything is damn near perfect, when i say wot isnt necessairly bad, i mean i have no knock, no pulled timing etc.
and wot doesnt necessairly mean 6500 rpm either, i can punch it briskly in 1st and 2nd, and get to where i wanna be quickly enough without using to much rpm at all

I feel ya, I was the same way. I started with a GReddy Peak/hold egt and tuned the S-AFC to run smoothly and keep temps below 850. That way I was conservative at WOT. WOT is just going to 100% throttle at any part of the rpms. You should be able to see were your boost is by looking at it somewhere in the middle of your powerband (again learning your car helps here). If it creeps higher, that is a different problem. But if all is well then you will see a true psi at the peak of your powerband.

DYNO's are your bestfriend for learning your TRUE anything about the car. Get yourself a DSMLink. From your previous post, you seem like the kind of guy to want to know "EVERY & ANYTHING" that is going on with your DSM. AS AM I. I got the logger and yes it helps, but I NOW want to go all for a DSMLink or maybe even the AEM for the wideband help.


As for your turbo track time question...well....lets just say I am not happy with the time, but the MPH was giving me hope. With the stock suspension I got a 14.0 at 112mph. There was alot going on that I had to drive it conservative in 1 and 2 gear. The clutch was going and the tranny has a problem. Which inturn decided to blow itself the next day. My 60' foot for the 14.0 run was a 2.9 I believe. Not your best, but with the stock ride hieght and some NO name tires, what can I do.

Since then I have upgraded the suspension and went to a AWD tranny for gearing purposes and the potential to convert later on down the road. The tranny was dead and the AWD was only $400 to drop in with some minor changing to make it work. Man, there are so many things that have come into play that it is hard to type on the internet. I know it sounds like excuses, but they are legit haggles that most FWD people have.

Next weekend, with the new suspension, I am hoping for some good numbers. Thanks for the compliment on the car!! You need to trade me rims!

i got WOT only to test for leaks / problems nowadays but i finally fixed her and boost 16 psi with the evo III..

as for problems with WOT, the DRIVER is what's responsible for keeping the tires from spinning. launching hard at 4k rpms and holding WOT all through the gears will net you a 16 second slip.. i personally just control the spinnage with pedal pressure. if you feel the car is going to slip, just let off the throttle a bit.. all it takes it practice practice practice.

on midnight.. that MPH is GREAT .. get that suspension on and report back because i need to decide on a setup VERY soon.

i'm thinking LSD insert [ yes i'm cheap ] , eibach sportlines ??? [ the one that lowers the car more ] i already have toyo fz4's, and kyb gr2/agx

hopefully later this summer slicks will be on the car for track runs too

yep, you hit the nail right on the head. i like to know about everything going on, and how well everything is running. i have been considering some different tuning directions. like i was wondering if a datalogger and safc is good enough for proper tuning. or if a dsmlink isnt to much more expensive and worth it to pay the extra buck. it will be a while before i have the cash. but i like to have things planned out in advance. thanks for the help fellas!

Thanks. The suspension is on and next weekend will get me some times to post finally.

As for your setup. If you still have the T25 for now or even if you are upgraded, save on the Insert and get yourself an expensive TRUE LSD. You will love yourself for it. I got a set of Tein springs and they sit nice, but if I could do it again I would go the route of Ground Control coilovers. They will help you more than any spring. If needed, you can set them to look like a girl in 6' heels. Like an SRT's setup. Take out your spare and lighten the rear as much as possible. The problem some have with srings are they sit at different hieghts in the front because of weight distribution. Fix that with a set of good Coilovers. You will get your times down like that.

If I could do it over, YES. DSMLink is deff worth the money and about the same in the end. $300 for S-AFC and $200 for a logger setup is pretty close (little morefor the dsmlink) to what you would pay for the dsmlink provided you have a laptop already.

I watched a guy tune with an AEM EMS this weekend. Looked VERY involved and like a true expert tuning device. Probly more advanced than I would like to get in, but deff. nice product.
