i have a 98 r/t that redlines first and second but struggles to in third, fourth stops at about 6000rpm and fifth won't go past 4000rpm. if anyone has any suggestions i would love to hear them.

 

motor isnt making enough power to do it. your first and second gears have some wild gearing so your motor doesnt have to work as hard to get things moving. Once you are moving and get into the taller gears there is less assistance from the transmission gears in getting things flowing.

 

Someone I know had the same problem with his jeep, but it was an automatic.. Check your Cat., it may be plugged!

 

140 hp can only get you so far. They werent designed to be a full on race machine. If your really after the power, look into a turbo setup.

 

i dont have any problem getting my r/t up to 120-130....so there must be sumthing wrong

 

start with pulling codes, just 'cause the light ain't on don't mean you have no codes. 2nd a COMPLETE tune up and use copper plugs. give some feed back, good luck.

 

i can red line my neon in 4th gear and i almost got it there in 5th but ran out of straight stretch at around 130

 

well even if you had straight stretch you still wouldnt of been able to reach over 130

 

5th gear is just a cruising gear, it makes no power whatsoever.

 

ok so i removed the cat and put on an obx header and a 52 mm TB. it accelerates slightly faster but still have the same problem. do copper plugs make that much of a difference?
