can any one one give me pros, cons, and tips on power shifting as opposed to reg in race situation?

Just a Pro. You have the slightest lag if you shift it without speed shifting. Also you could load up the engine with to much fuel by several on off throttle manuvers. But most of all you are controling your engine braking when shifting as well. You might want that torque range you get in a lower gear but you don't want it to engage at a low Rpm. Could put you into a slide or spinout.

If you are going that fast most likely you are in deep trouble...  If you must know what to do in a blow out though, no matter what DO NOT HIT YOUR BRAKES!!!!!  You will be completely out of control.  Take your foot off the gas and slowly down shift (on automatics it would be the "L" gears) until you come to a stop.

I would personally suggest you not to make this mistake as the company(chevrolet) knows whats best and have specially tuned the car for it's max performance..in changing the engine you will face a number of problems like lesser fuel efficiency and as we all know gasoline prices are soaring and the car won't respond very fast.you will also face gear shifting problems.pls don't make this mistake.gud luk

at or about the going rate would be best, anything else and i think you will struggle to shift them :-)

Bicycles these days have things like index shifting, this develpment has made cycling much eazer for the beginer. Back in the old days, "the 70's", I had to learn to shift by feel. This led to a lot of looking down and back, while working the shifter levers," once rode head on into a parked car doing that, even the people who owned the car were laughing". So you have the advantage of this wonderful index shifting. When approaching a hill down shift as you feel your legs begin to bog down, with index shifting you can down shift 1 gear at a time untill you reach the top of the hill. As you become stronger you'll down shift less. What you want to do is keep a steady cadence," RPM of the cranks", and use the different gear ratios to fit the terrain.

Usually the dealership wont make those kind of adjustments because they are not allowed to make any modification out of the factory specifications. Usually they don't have to adjust the computer, only change the O2 sensor(check out the ones from Bosch). I would recommend trying to ask the ones that sold you the air intake and headers and tell them about the problem or get a sports chips. What they usually do is re configure the computer to get the 100% of power  out of the engine.  Normally they are programmed to work in a 80%.

Learn to establish a good shift-brake ratio. The majority of society are unable to apply the necessary established perimeters that are needed. Good luck!

Been down this road with an 82 Transam that had crossfire injection.\n\nMy recommendation for you is to replace the intake manifold and install a holley 4 barrel.\n\nIn the end you'll save alot of time and effort.

Torque is less of an issue when racing because you are always running the engine at high revs. I raced stock Fords here in England and the revs were always between 4500 and 7000, even 4500 was quite unusual.\n\ni would normally take power to weight over torque to weight any day.  Weight works against any race car as it strains everything, tyres, brakes, etc.\n\nAlmost certainly in a race there would be other deciding issues such as set up (camber, toeing, etc)

wow man that sounds a little crazy, like rocket science. i have standard 6in rotors and they rock and have never even in extreme conditions given out on me or had brake loss due to heat. i know your setup, id consider just doing one rear hyd. brake for weight/racing purposes, maybe even not use front brakes at all or just use v brakes for front.

chip, GT40 air intake, cat-back exhaust, free-flow cats, h-pipe. The easiest thing to do is change the oil to synthetic. Less friction=more power

The headers will shift the powerband slightly to the right. If your driving features more low RPM operation, you will have improved mpg, if you drive in the high RPM range, you will have worse mpg.

Have someone who knows how ride with you in an area where there is very little traffic.  And remember, push in the gas and ease off the clutch.  That is the hard part, once you get that part down, shifting is easy.

If you're talking two identical STOCK factery issue cars, the guy with the manual trans will win, because he can get off the starting line with the engine up in it's power RPM's\n\nNow, if the guy with the auto has a tranny set up for racing,\n(high stall torque converter, shift kit)  HE WILL WIN!!!\nnearly always, because he will NEVER miss a shift, and will never break axles etc etc and he too gets off the line with the eng cranking max horse power

If you are just doing normal driving with the original engine and trans than you should be OK with the factory rear end. But The Dana 60 is the rear end that most of the drag racers use. If there is anyone that is hard on a rear end it is a drag racer.

YES, BUT IT ALSO DEPEND'S ON YOUR SHIFTING RANGE OF THE REAR GEAR'S, TRANSMISSION, AND SHIFTING LIMIT'S OF THE CAR'S ENGINE.\n\nYOU CAN SHIFT AT THOSE RPM'S., BUT YOU MIGHT RUN THE RISK OF BLOWING A SEAL, OR GEAR, OR MAYBE EVEN YOUR TRANNIE AS WELL, ESPECIALLY IF THE GEAR'S OD THE UBOVE MENTIONED ARE NOT SUITED FOR THOSE KIND'S OF SHIFTING CHANGE'S THAT  YOU MIGHT WANT TO TRY.\n\nALSO, YOU MIGHT WANT TO CHECK YOUR DRIVETRAIN AS WELL TO SEE IF YOU NEED NEW BUSHING'S FOR THOSE KIND'S OF SPEED'S AND POWER RANGES.

Why wouldn't you make an Tempo into a race car?...It's the perfect sleeper, and like it or not, I've seen quite a few made to race...\n\nDid you change the Onboard Diagnostic System?...Because it should be OBD-I...
