ok I went to the drags for the first time in my EVO... btw this is my first AWD car...

anyways I have 3 questions... first off
1) does anyone leave their foot on the gas while shifting or no???(it seems the answer is no so far)
2) what does everyone shift at a ran to 7k every gear...
3) here are my times what the hell happened ( I'm not worried about reaction yet I need to get my launch down first)
1st run launched at 4K
60ft --1.973
330 --5.679
1/8 8.781 @ 80.48
1000 ---11.456
1/4 13.731 @ 99.12
2nd run launched @ 6k
60ft --1.931
330 --5.553
1/8 8.596 @ 82.94
1000 ---11.272
1/4 13.560 @ 96.49

as far as I can tell I shifted at the same points from 3rd to 4th but I was about 2.5 MPH ahead of my 1st run by the 1/8 then I finished almost 2.5 MPH behind at the 1/4... I imagine that if I could fix whatever I did that would be around a 13.35 run...(correct??) also I think if I rev higher at the start I could get to a 1.8 60ft.(Correct???)

thanks a lot guys

1. NO, that is really hard on the car, so not many if any do that
2. It vary's but the longer you stay in a gear is usually better, hence the dynoflash, p2, xflash raising the rev limiter so you can take each gear further.
3. Their is nothing wrong with your times. your times are better than most stock times. Not very many stock evos are below 13.5 From what I have seen 13.7-9 is average.

 

ok thanks a lot, but I still think there is something wrong when you lose 5mph thats a lot maybe enough to get an extra tenth or 2

If you nail the 60ft really well it usually has less mph at the 1/4. When I had a better 60ft my mph was usually a couple seconds slower up top but I would have a better time.

 

my best times were leaving at 5500 sliping the clutch shifting al gears at wot no lift 7200 to 7300 .


60ft 1.887
1/8 8.445 mph 82.11
1/4 13.290 mph 101.5

 

I noticed your 1/8 mile mph was alittle faster in your 2nd run but your 1/4 mile mph dropped off and was slower. I would take a guess and say you had a really slow 3 to 4 shift to drop off that kind of mph.

 

Seems like it ought to be quicker to maintain full throttle while shifting. It's only going to hit the rev limiter when you push the clutch in - shouldn't blow the motor or anything. Might keep your boost up between shifts too. Just theory mind you, I haven't tried it.

 

Slipping the clutch a little (very little) off the line will enable the turbo to build boost and not bog the motor off the line and not spin the tires. Play with it you should be able to get 1.8 to even 1.7 60 ft at sea level on a good track. You need to not power shift mainly in the lower gears sometimes higher gears do not matter as much since the car is moving faster. It will cause the motor to bog after you shift for a moment. This is because it unloads the turbo then reloads it dramatically causing the boost to back up slightly then have to rebuild again making the engine temporarily produce less power. You will have to experiment with shift point to get the best times. Some generally say shift higher in the lower gears and lower in the the higher gears. You definetly need an accurate tach with a shift light! The reason being is the higher shifting in the lower gears will allow you to get moving quicker and the lower shifting in the higher gears will produce more load on the motor producing more boost from the turbo. creating higher trap speeds. You reduce your e.t.s more off the line and increase you m.p.h. more at the end. If you miss 4th gear and then find it and finish under power your e.t. will not be affected that much but your mph will be greatly affected. same goes for the opposite miss 2nd your et will suffer but the mph will be close to the same.
Shifting normally but at high speeds will keep your boost up more so than power shifting will unless you have a clutchless shifting tranny which keep the engine under a load at all times during a shift or an automatic.

 

Hooking up better off the line will reduce your mph at the end slightly but will lower ets. Spinning slightly off the line can increase your ets and increase you mph at the end. It simulates adding length to the track when you spin slightly allowing you to reach a higher speed in the same distance. If you spin badly and bog when you shift gears it will lower your mph and increase your et because is simulates a longer distance down the track and you slowed down momentarily in the middle of that "longer track" I can guarantee a stock tach is not accurate. Get an expensive high quality tach with a shift light. It will help you be more consistent and allow you to log your changes in shifting points to see the differences they make.
The differences in your 8th mile e.t. and mph is from you better 60 ft. You put more power to the ground at the beginning of the track. which made you accelerate quicker! The end falling off could be from many things partly because you hooked up better in the beginning maybe shifted differently "stock tach" or a wind hit you and slowed you down. The only reason your car cant accelerate faster than it does is because of wind resistance! If you notice you run 82mph in the first half and only 82 to 99 in the second half! this is because the air is more resistant as you go faster through it! If you were on the moon you would gain just as much speed in the second half as you did in the first half! meaning you would run 160 plus in the quarter!!!! The only way to achieve this on earth is to increase you power to you can accelerate faster at the middle and end of the quarter more efficiently. That is why when you ride in more powerful car than yours it will seem much faster in 3rd and 4rth gears than you car is but 1st and 2nd will not be that much different unless the faster car has a large amount of power over the slower one!

 

leave you foot on the gas pedal while ****fing ... you can do that ... but you have to shift it quick or you will kill your tranny ... leave you foot on the gas pedal while shifting ... it's called: powershifting ... by doing it, helps you get better launch at the line ... normally ... people let their foot off of the gas pedal, hit the clutch and then shift ... it's called: grannyshifting ... grannyshifting is a basic shifting ... anyone who knows how do drive a stick shift car, then of course ... powershifting requires alot of practices to perfect it ... my recommendation, don't try it on your new car, such as: Lancer EVO VIII / Subaru STi ... haha ... practice on an old manual car for first time's sake.

 

Who fed you this load of crap? If it takes you 8.6 seconds to reach 83 mph and you run a 13.5 at 96 1/4 mile that means you only have 4.9 seconds (about half the amount of time) of acceleration in the second 1/8 th mile of the race. That is the major factor in why your mph gain is less substantial in the second half of the track than in the first half. Yes, wind resistance does play a MINOR roll in this. The faster the car the (proportianally speaking) smaller the gain in the second half of the race.
