Stock, but cranked up, T1's...

[aerosmith145]

Hey guys, I was just curious about something. I just bought an '89 T1 Lebaron. I immediately converted it to an intercooled setup and turned the boost up to ~13. It has low miles, and runs excellently, though it seems to have awesome low-end power, and feels like it runs out of steam almost immediately after it hits full boost. As in, I can brake boost, and take off like a bat-out-of-hell, then after I finally gain traction and start accelerating, I feel like all that horsepower has dissipated and it feels nearly stock. I've had 4 T1 cars with this setup, and they all display the same type of behavior. Am I just getting as much flow out of the factory mitsu as I can with the amount of fuel provided? Is this the way all cranked-up T1's act? My only advantage over people is off-the-line takeoffs, and highway boost roll-on's.

That's another thing, the car feels faster if I give it a part-throttle boost situation and let it pull, rather than flooring it and letting it downshift. Then it just sucks. I assume it's because of the longer gear ratio vs. torque scenario when it doesnt downshift. All my auto T1's have done this as well!

Any thoughts?

Garret or Mitsu turbo?

you could try retarding the cam 2-4 degrees which will move the powerband up in the rpms

but most likely its the mitsu (and stock exhaust too?) choking that 2.5 up

slap on a garret it wont spool up as fast but you will get more high end power

yeah, that's what I was thinking. I hacked off the exhaust for the hell of it today (open header), and the car feels even slower. Maybe there's just a bigger noise/speed ratio lol Anyone else ever experience this though on a bone-stock T1 with higher boost? Does the Mitsu really hinder it THAT much?

Yea I had the shadow up at the strip the other night and its quick to the 1/8th but after that its just wheezin along with that tiny turbo. My best MPH of the night was 88.54 in the 1/4 and 70.42 in the 1/8th on the same pass.

Hey I was thinking of adding an intercooler to my 86 laser. got any pics of the set up?

Are you talking to me? It looks just like a factory TII car, but with a silver intake manifold and V/C.

Oh ok. And hey get rid of the mitsu

IMHO try a computer thats actually tuned for what you changed on the car.
I know the mitsu is not the best, however power can be found with a proper tune now that your intercooled and running open pipe. You might be surprised what a difference it makes.
