I was so happy my 87 GN actually made the tires squall last night !!!
I had to come it to work last night about 1 am and it was 60 degrees and clear... This car likes cool air night and day difference. I punched it leaving the parking lot and when the boost came up about 10 feet out the squalled the tires just a little bit. It did not break loose but it was all the tires could hold and it was a concrete parking lot too !

Anyway silly, but I was worried about my car, but its Balls seem to be dropping as the temperature drops....:biggrin: :eek: :redface:

oh it sems to be making about a lb more boost than it was on cold days then it bleeds back to the 15 I set, but it hits 16 at the beginning. Is that normal ?
 
A 1psi boost spike is acceptable to most. I wouldn't worry about that as long as it doesn't get any worse. A decent manual boost controller will fix that. Any boost level over 16psi is where the TRs really start to wake up.

Haha, you said, "squalled." Glad you are having fun. That's what it's all about. :biggrin:

BTW, the Y-hose uses a special connector with an internal restrictor like thingy in it. A regular ol' vacuum tee will probably not work correctly.
 
The previous owner made the T .... I copied the list of things that were done into my sig so you guys can see what I am working with and I hope get me lined out !.
 
Well Crap.... 76 degrees I took the GN out with the wife and was going to impress her so I stood it on the brakes got about 10 psi tires spinning left in a cloud of Firestone and it just spun about 15 feet and pulled to 60 in maybe 7-8 seconds and felt like a slug again.... feels 50 hp down from yesterday.. was the extra 140 lbs of the passenger doing it ? ok I'm frustrated all over again.. :mad: :mad: :mad: :mad: :mad: :mad: :mad: :mad: :mad:
Will a Alky kit make it think its 60 degrees all the time ?
:confused:
 
The alky kit will let you run 22psi on 91 octane fuel ALL THE TIME.

.....Even better than 60 degrees:eek: Your tires won't have a chance!;)
 
I give it half throttle in 2nd gear and Im all over the road roasting the tires when the tune and weather are good....and I still bitch and moan about it being slow. Wish I could find happiness in a tire squeal:cool:
 
Hey want to trade cars !!!

LOL

Wish I understood what turned these cars into beast... mine is still a wimpy pup.
lets see I read about cars at 24 lbs of boost running 10's
I don't think 8 psi is gonna do it for mine... ok need more fuel bigger injectors...need better inter-cooler ? need Alky.....Need scan tools and data loggers.... I am just lost at the moment... I will continue to read and ask dumb questions though until I do figure it out .

I just have to vent to people I figure went through it the same pains at some point with these cars every once in a while.

Well judging by your signature, you have a ton of room to grow. You really dont have much if anything done to the motor.
The most common first mod is exhaust work, including a downpipe, but I have all stock exhaust with the exception of an extrude honed exhaust elbow on the turbo. Theres 3 things that will make the biggest difference on the car.
Bigger turbo.
Bigger intercooler.
Higher stall torque converter. The Art Carr non lockup 16930 TC is a beast of a torque converter. When I pulled it out in favor of a stock TC, it felt like I lost 100hp because for one, the much smaller diameter (9.5") has far less static inertia to overcome, so it can rev up much quicker, and the higher stall allows the turbo to spool up much quicker.
The intercooler can be as simple as finding a stock one thats had the duttweiler neck welded on, or buy one and have it done for you. I found mine on ebay with it already on.
The TE-44 is a GREAT street turbo. Spools very quick and is good to mid 11's on some GN's. But there are plenty to choose from.
From there you should get an alky kit, crank it up to 20-25psi and have fun...but work your way up and keep changing the tune as you increment up in small amounts of boost, or your engine may not like you.
But of course, none of this can or should be done without going to a bigger injector first. And get yourself a scanmaster if you dont have one...every turbo buick should have one, and get a good adjustable chip.
With this, you should have a solid high 11 car if you have sticky tires and drive it right.
Then come ported heads, ported intake, etc....but the engine can benefit now from ported heads and intake. With all that, the path to the cylinders will be opened up alot which will cause the boost reading to fall, because the restriction has been reduced. It may drop 5-6psi, but you'll still have the same amount of air going in the motor...actually a little more. Then when you crank the boost back up to 16, you'll have an easy 80hp gain with no knock.
