MrMeanGreen Posted September 22, 2005 Report Share Posted September 22, 2005 Well, to put it mildly, anything over 20% throttle from a roll (even accelerating to change lanes) causes the RPMs to shoot up and the car to not go anywhere. However, this is ONLY from a roll. Going from a dead stop, the car launches and shifts great, even at 75% throttle. I'm gonna look at a few things starting with the new program I'd uploaded to the PCM for the 60# injectors. I'm also gonna pull the pan and check the tranny fluid. I'm wondering if it's not in the PCM settings, if it's the tranny or the stall converter. I have to see either way. Tranny: Pull and send off to Berberich for a rebuild. It's been two years since the last one, so I'll need one anyways this winter. Converter: Time to send it in anyways, I get a free restall 4500 maybe? I'll see how everything looks tonight when I get the car up in the air and apart Quote Link to comment Share on other sites More sharing options...

Tinman Posted September 22, 2005 Report Share Posted September 22, 2005 Time to ditch the slushbox and add a pedal I might swing down and lend a hand, I need to bring you that a/c compressor and take a look at the wiring harness in your firebird jr. anyways.

fattyona12 Posted September 22, 2005 Report Share Posted September 22, 2005 Just remember with you stall speed Ant. This is a street/show car....4500 gets your tranny hot trying to street drive and shortens the life of it greatly. Quote Link to comment Share on other sites More sharing options...

Mensan Posted September 22, 2005 Report Share Posted September 22, 2005 4500 stall=WASTED TORQUE on a car with as much bottom end as the Firebird. Quote Link to comment Share on other sites More sharing options...
excell Posted September 22, 2005 Report Share Posted September 22, 2005 4500 stall=WASTED TORQUE on a car with as much bottom end as the Firebird. Actually, if it were a 100% race car, I would go with a 4500. The car makes a LOT more power up top than it does down low - especially with the parasitic drag of the supercharger. It only needs enough torque to get it off the line quickly. But since it isn't, we'll be going a different direction. Quote Link to comment Share on other sites More sharing options...

gillbot Posted September 23, 2005 Report Share Posted September 23, 2005 If you go up to 4500 you are dolt. You know the rest of my opinions, get me pictures. I agree, Speec Inc. recommends converters in the 2800-3500 range for ATI powered cars from what they've been telling me. Quote Link to comment Share on other sites More sharing options...
