I need more power

[turbotrix2004]

hey guys i am looking for some help on how to get some more power out of my car. I don't know how much hp the car has now but i would really like to be around the 4-450 hp mark.
these are mods that i know were done to the car;
18 lbs of boost
rjc manual boost controller
caspers chip
deka 60 lbs injectors
fuel pressure regulator
fuel pump hot wire kit
k&n filter attatched to maf
208 comp cam
egr delete
precision turbo (don't know specs)
3" downpipe
full exhaust with pitbull mufflers and no cat
high stall torque converter dont know which
rebuilt trans with shift kit

If it runs well and you know how to keep it in a good state of tune, throw alky at it and you'll be there if you have anything over a stock turbo. You'll need 25psi or more most likely to get there. More info on your build is needed.

see that's the tricky part, i don't know the extent of the work. it was done before i purchased the car. i know it has a stall converter but don't remember which one. i can crawl underneath and find out if needed. is there a way to find out whicjh turbo i have? would getting a different chip help?

Start reading the links below or find a good turbo Buick guy in your area. There are a few guys in the NJ area I believe.

Well if the turbo has a bolted on inlet bell chances are it's a stock or ta 49. Only real way to tell is to measure the wheels. If you're looking to make that much horsepower I would probably prep the t4anny. That will be the wink link. Alky will be needed also

You will also need a way to increase the boost. Adjustable waste gate and or a rjc manual boost controller.

i know the trans was rebuilt with shift kit and i also have that boost controller... i updated first post

So as far as bolt on parts are concerned there is nothing without alky

 

[psycho6cyl]

Start with alky. Get the appropriate chip for it. Also get a turbo tweak chip or bob bailey's chip from full throttle. Buy razors kit and have some fun

 

[Mr.Spool]

need to read the links you have been given its very usefull and explains how too's and combinations,especially if your going to be wrenching on the car.getting someone who knows these cars to set it up for you will be much easier and quicker.

You could use race gas too but it's hard on O2 sensors in the long run. All the bolt on parts in the world won't help you if you can't turn up the boost and you can't do that without octane. That's why everyone says to turn up what you have before you throw parts at it and make it run worse.

That's discouraging..... I had an srt4 with bolt on parts and had just over 400 hp on it tuned with super. No race fuel and no alky

Apples and oranges. That's an efficient four cylinder engine with a good head and 4valves per cylinder. You're trying to shove air in an iron V6 with ok heads at best that was designed over 50 years ago. And is that 400hp to the wheels no octane adders?

Correct to the wheels with pump gas

Admirable. What turbo?

 

[jasjamz]

Get sticky tires and take the Buick to the track. 5 gallons of race fuel when you get there to play it safe.

Before you can go anywhere you need to know where you're starting....

Gt3076r but those cars are surprisingly fast and react really well to mods

What are your goals for/with the car? You looking to bench race, as in "well, my car has 450 hp!". Are you looking to run some magic number at the drag strip? How about a late night illegal street racing event with a $2k buy in?

Remember, these cars are known for their accessible torque and ability to hook up on the street. I dare say there are quite a few TR's on this board that could smack the hell out of higher HP cars out there. The only way I know of to run low boost and put up big numbers with these cars is with a stroker motor and good heads.

As an aside, I've met some really cool kids driving SRT4's. While they're not my thing, they do seem to be able to make really good power out of those setups. I wouldn't want to take a drive of longer than 30 minutes in any one I've seen, but I do appreciate what they're doing.

Alot of horsepower without being able to get proper traction at the tires won't do you much good on the street or strip, out of the hole the torque the motor makes is what gets the car moving. There's alot of higher HP cars out there that don't have the brutal acceleration experience that the TR's pull off with the very useable substantial torque the little turbo v6 makes even in stock form. I'm not saying that there arent cars out there that accelerate more rapidly, but a majority of them are the price of at least 2 or more really nice TR's with insurance rates sky high and not necessarily able to hold 5 people with alot of trunk space.

Having the heads ported and cleaned up to make them breathe alittle better, having better flowing mufflers over the stock muffler even if you don't go up in size of diameter, a good chip burned for 91 or higher octane, 42lb / hr or higher flowing injectors matched to the chip, a higher fuel volume flowing fuel pump, upgrade at least to a more efficient stock location stretched intercooler, having decent high / ultra high performance z rated tires for more grip, using stiffer valve springs and having the transmission in good working order to handle those changes would gain you some boost in performance over how they came from the factory without turning the engine into a grenade and not leaving you with having to take out a loan to pay for it all. It's amazing what boost in HP and Torque those mods alone would do and leave you with more than you'd think in added performance along with the added reliability.
There's alot of potential with these evil half dozens, just has to be tapped into and awaken.

But if it isn't running right before doing some of the mods, you won't know what you got and overspend easily on parts that without a good basic tune aren't gonna net you any gains.
That's why there's alot of TR's out there that have builds done that left tons on the table and some actually have a balanced setup figured out with a good tune that gained tons who left not nearly as much on the table.
