hey guys a lil intro. The car is a 03 evo 8. has small mods done by the previous owner. Hks intake Megan racing manifold and 3 inch down pipe and 3 inch test pipe from the cat back its gotta be like 2.25 or 2.5 cuz it shrinks a good amount. the car has 58k on the clock it has the original clutch but has had the 60k tune-up a few months back before I purchased the car. now when I got it i changed all thew fluids (motor oil, tranny oil, tcase,rear diff). I haven't changed/checked the plugs yet tho, yea i know stupid. But long story short i took it to e-town last nigh for a test and tune and the damn thing struggled to break 15s. My best run of the night was 14.7 @89.96 my best mph was 92.92 but i ran a 14.8.

I know I need to changed the plugs but damn something else has to be going on.
btw: the car is full weight with a spare and a jack and 3 tool boxes in the trunk

Thanks in advance

Honestly, a lot of that trap speed can be based on how your drove the car, to some extent.

If you're taking a long time to shift, that time you took to shift gears need to be looked at as time the car is not accelerating. Most people who've been racing a while can get it down to under .1-.2 tenths of a second to complete the shifting process. Since you have an 03, with the taller 3rd and 4th gears, you should be crossing the traps in 4th gear, so you will have to have shifted 3 times. If you're taking longer to shift gears, then that time it took you to shift is time the car isn't spending accelerating, so you'll end up trapping slower than someone who drove your car but shifted quicker.

Do you have a breakdown of the timeslip? That would at least give us an idea of what to suggest to try to work on to improve your ETs, and your mph will end up improving as a result.

Please don't think I'm knocking your driving - everyone could be better than they are, with more practice. When I started racing, I had made it to a point where the car would run consistent 13.2-13.4. Then I started going to Atco a LOT to practice, probably twice a week. With no other changes to the car, I was able to get the car down to the 12.5-12.4 range, only by improving my driving skills. The mph also went from 102 to about 109, just by me getting better at driving, and spending less time shifting.

yea it was my first time at the track. and this is my first awd car my last car was a s14 240sx w/35r. but my slips break down like this:
3rd run
r/t .408
60 2.1(my dd so im not trying to break the trans/t-case)
330 6.097
1/8 9.399@75.17
1000 12.2
1/4 14.765@89.96



2nd run

r/t .544
60 2.26
330 6.18
1/8 9.51@74.32
1000 12.39
1/4 14.823@92.92

1st run (missed 4th)

r/t .783
60 2.309
330 6.244
1/8 9.556@74.44
1000 12.509
1/4 15.036@89.76

1. Boost leak check.

2. Is it tuned?

3. Your 60's are not great. Do you have the 2-step (would have to be programmed in on the 03)?

I suggest checking for a boost leak, getting it retuned, getting the 2-step adjusted so its useable.

Judging by the slips, if you can just improve your 60' and 330' times, you'll be amazed how much that'll lop off of your ETs and raise your trap speeds.

Certainly SmikeEvo's suggestions about boost leaks and tuning apply, but I'm sure even with just more practice you'll watch those ETs drop.

The 60' time tells you pretty much everything about how you launched the car, and the 330' time tells you how your 1-2 shift was. Start by trying to get the 60' under 2, and the 330' under 6.

Then, once you've improved the most important part, the driver, all of the other changes you'll make will yield bigger results.

yea first purchases was the tactrix cable and a lc1. i logged the first run but then stopped after that. I was so focused on breaking 15 the next runs i didnt really care about anything else. I set the 2 step at 5500 I think I might raise it to 6k tho. I need a boost controller too. but I wanna get the car running the way its suppose to before i add any variables to the equation. I might do a boost leak test because something has to be up

btw its a stock tune as far as i know

id check for a loose nut behind the steering wheel, my 04 has driver issues as well. my old eclipse ran consistent 14.7's with "free mods" and with a better driver ran 13.9. so that tells you quite a bit right there. like the rest said, get tuned, get the mbc and check for boost leaks. also go ahead and change out the plugs if they werent included in the 60k (should have been part of the 60k, go with the factory parts if not) and have the timing belt changed if it has not been done already, if you arent 100% sure it was done, go ahead and do so, the money spent is worth the peace of mind IMO.

Let me guess you've been waiting to use that line for a while huh?
seriously tho. I can drive. I cut some ****ty lights but as far as shifting im positive im not slowing the car down to the tune of 14.7 im gonna check the plugs and do a compression test also a boost leak test. the 60 ft isn't gonna improve that much its a stock clutch and my daily i cant take the bus to where i work so i'm not trying to break any drive train parts but the car has no top-end.

I would disagree based on the times in your first post. I think you are not launching right nor shifting fast/hard enough. There is more to it that there seems.

And if 5.5k was too high, then 6k wont be any better. Looks like you are slipping too much off the line. If the car does not bog, then the 2-step is in the ballpark. Too high and you will just spin all four off the line.

Finally, practice, practice, practice. I had over 400 1/4 passes in my car. And I had a ton of RWD experience before that, and I didn't even cut great lights (the boost leak didn't help my times either).

well i get another go at it tomorrow its Evo vs. Sti day at e-town. I'll try to post slips but e-town's slip printer thing needs ink i can barely make out what i ran.

Well I think I know why it ran so slow now. Clutch is slipping I just took it for a drive. Any body got any recommendations to get the clutch to grab a lil bit better. I'm trying to run at e-town tomorrow and a clutch job won't be ready by tomorrow. Will any adjusting of the petal help it grab or does it just change the engagement point?

+1 That is the main problem...

No its not the clutch isn't grabbing its slipping I didn't notice it at the time but it is slipping. the car has 58k on it i picked it up w/ 57k the clutch is the Original clutch. This is the problem. now any one for clutch recommendations? the car is dd but i wanna take it to the track every other weekend or so or maybe once a month. Im leaning toward Qm twin due to price and it being a push style and not many people have had problems with them. exedy twin push is out of the question. 2300 bux my clutch better be made of gold. let me know what you daily driven weekend warriors are running.

wow, that sucks...

i'd say boost leak/ tune + driver modz
