Whats with my big difference in trap speed?

[Kdubslugga]

Im wondering why my 1/8th mile trap speed is so slow and why 1/4 trap speed is pretty decent for what i have done?

My buddy has a 90 LX with exhaust and AOD and 2.73 gears and he traps 75.06 in the 1/8th but runs 15.1s. I trap 76 mph in the 1/8th but i run 13.7s/ Now his trap in the 1/4 is only 93 something and my best trap speed to date is 103.01, now to me thats a huge freakin difference. Im thinking its because I shift into 4th like 20 yards before the 8th mile marker and i think thats really killing the 8th mile trap speed cause i cross the finish like at like 5800 rpm.

I raced an SRT4 at the track the other day with a stage 2 upgrade and he ran a 13.4 at 104 something to my 13.70 at 102 and i had him till about the 1000' foot when he passed me. His 1/8th mile trap was 85 to my 76.08mph So is there anything i should worry about or do i say screw it and worry only about the 1/4 mile stuff

Your shifting into 4th before the 1/8th? I shift into forth about the 1000 foot mark an i got 3.73's What gears do you have?

haha, damn i was just about to check out my 1/8th mile trap speed on a time slip i had in my wallet, an it says I ran a 8.8 @ 524.88 miles an hour!!! wow. Well, the other guy ran a 13.5 with a 80 mph 1/8th trap. Your trap speed seems to be pretty correct for your 1/4 mile time. I would just stick to the 1/4 stuff, less confusing that way lol

Your buddy needs a converter and some gears so he can break out of the VTEC'sET zone!

to late 90mustangGT we've already begun the T5 swap on his car no converter neccessary. Oh well just thought it seemed a little low in the 1/8th guess theres nothin to worry about

Well, throw a good torque converter in the trunk for safe measure.

The t5 swap will make his car a ton more fun to drive, and faster too.

Try having my issue. my car traps mid 85 mph in the 1/8 and my dads was right there mid 85 mph. In the 1/4 mine trapped 106 and his was trapping 110. I was only gaining 20-21 mph whereas he was gaining about 25 mph. There are tons of factors that control this...

I will say when I was going 103 mph in the 1/4 I was trapping 80-82 in the 1/8th, your 76 seems low! My guess is it has to be that shift taking place right there thats doing it!

Try powershifting. Your car may be laying over too far between shifts. He has an auto, so the rpms probably aren't dropping much.
