Tonight I went to the dragstrip for the very first time in my 03 evo 8. I only got a couple of runs in, but I ran the same time 2 out of the 3 times. I ran 12.46@115 once, and 12.47@115 twice. I can't figure out what I'm doing wrong. Below is a breakdown of my timeslip.
r/t -.481
60'- 1.96
330-5.391
1/8-8.149
mph-88.51
1000-10.516
1/4-12.47
mph-115.34

My mods are tbe, 272 hks cams, intake, aem ems, and intercooler upgrade. I dynoed at 357/355 pump and 389/387 on a mix of pump and race. Warralton, or any of you drag race gurus wanna drop any suggestions. Is it me being a drag race newb, or do I need to take a look at my car?

 

What were you expecting to run? How was your launch? I think you shouldbe able to improve on your 60's.

 

I was hoping for high 11s since I've seen a few evos with similiar power running 11.8-11.9.

 

Well 12.4 isn't all that bad, but you can do better, your trap speed is pretty good, and with better 60fts you can see very low 12s/high 11s. So to answer your question, it's not your car, it's you, but your not doing that bad of a job.

 

It looks like it's you. I think it's because you're just a drag racing newb, because you can't tell what the problem is, but I can tell the moment I see your 60'. Dude, you should be happy, actually. Your car is FLYINGGGGGGGGGGG and making great power. The fact that you're hitting 115mph on a terrible launch and average shifting is amazing. You are definitely backing up your dyno numbers.

Anyway, it's all in the 60'. You cut a 1.96 on this one...earlier tonight, I cut a 1.66. That alone is .3s, but it doesn't work that way. You would actually gain MORE than .3s if you could get that 60' down where it needs to be, because the affect of a good launch compounds itself through the whole timeslip. Let's look at our side-by-side to help you understand:
------YOU----------ME
60'- 1.96---------1.66
330-5.391-------4.94
1/8-8.149--------7.67
mph-88.51-------90.3
1000-10.516----10.02
1/4-12.47--------12.01
mph-115.34-----111.67

Now, look at the 60', 330', and 1/8th mile. Your launch was only .3s slower, but you lost ground all the way to the 1/8th at which point I'm a full half second faster with almost 2 more mph. Well, then on the back 1/8th, where it's all 4th gear power, you actually match me EXACTLY in time difference (4.3s), which means you overcome the 2mph and then outrun me to the end. Looking strictly at the 1000'-to-1/4, it takes you 1.95s, and it takes me 1.99, so you're outrunning me easily. YOu have an 11s car, brother...it just comes down to the launch and shifting.

 

^very true!
improve your 60ft time. A 0.1 improvement on your 60ft would work out to be more than a 0.1 improvement in the quarter.

with a 1.7 60ft you should be well on your way to 11's. Just practice launching and your reaction off the line.

 

In fact it's the same with me....if our crap track was good and i could get 1.6 60ft times I'd probably hit 10's.
but due to it being absolute $hit i struggle to get a good launch.. the launch pad is really bad and with hard launches i spin alot of tires in first.

 

Agreed. 114 to 115 mph is enough to run in the 11's with a 1.65-1.70 60' time and good shifting. The mph is pretty good, I woudn't worry about the tune or the car's condition.

you just need to go back to the track and practice launching untill you get in the 1.70 to 1.65 range. 1 tenth off the 60' is ususally about 2 tenths off the ET as a general rule.

you will also pick up 1-2mph once the launch doesn't bog out.

 

Thanks for the replys warrtalon, 11secevo7, and dsmotorsports. I plan to go back in a couple of weeks and see can I learn how to launch. I recently got the exedy twin carbon, and I'm just getting used to it, so that's part of my problem I think. How high do you guys launch to get the low 60 ft times? Is that the key to getting a good 60 ft, the high rpm launch?

 

Yes, that is the key. You have a very strong clutch, so you need to be launching no lower than 5500-6000, in my opinion. The truth is there are many ways to launch...it comes down to what works for you and your setup, but generally, you need to launch high enough to make full use of all that power, otherwise you just bog.

 

Ok, I to am on the quest for 11's.

I didn't want to post a new thread. If you don't mind I'm also trying to get some info.

Went to the track this past Thursday. Temp was low 60's no humidity, actually was kind of cold. You can view my list of mods below. The times were run with 93 octane, no spare, boosting 24 tappering to 22 psi. This was after putting the Unos MBC on at Buschur racing having Dave check the log on the EMS to see what I was boosting (my boost gauage is broke and I have no laptop).

My buddies say that my shifting could be better (none of them own a EVO). They suggest not lifting off the throttle when shifting. I'm unfamiliar with this and haven't really practiced it, that's why I don't do it. Dave says the mods should net me a high 11's low 12's. When I got the mods I told him I wanted a car to run high 11's with a good driver and low 12's with a bad one. Guess he hooked me up, hopefully the good drivers comes soon . I take it my problem would be the shifting, I've been shifting constantly at around 7500 rpms.

Any feedback will be greatly appreciated.

60' 1.714
330' 5.034
1/8 ET 7.759
1/8 MPH 89.46
1/4 ET 12.035
1/4 MPH 115.44

 

Well, man, you're right where you want to be. You're making great power, and your launch is really good. When comparing timeslips, it does appear your shifting is a little slower than it should be, but that doesn't mean you have to no-lift shift (NLTS). I lift on the 1-2/2-3, but I don't life on the 3-4, because it's so incredibly easy to do. What you do is you keep your accelerator planted to the floor while making the shift as fast as possible.

YOu will simply hit 11s by cutting a slightly better 60' (1.66-1.69) or by making this 3-4 NTLS. The other way to do it would be to just make those other shifts even faster/smoother than they already are. Another possibility would be to run race gas and turn off the meth. With some 110/112/116/C16, people tend to get another mph or 2, but only if they know how to tune for it. I assume that you wouldn't know how to adjust your AEM EMS to account for the race gas, so that may not be feasible.

 

Thanks for the info.

I'll have to try the NLTS on the 3-4. Since I got the EMS from Buschur racing I have one free map left for tuning which would be race gas. I'm trying to hit the 11's without it for right now. That's the goal for me right now 11's on 93 octane. I think my good launches were neglected from tire spin and car getting sideways out of the box (I'm suer the track was very cold since I was shivering that night and you could see your breath, although I just got back from the desert). Maybe next year I'll break down and use some race gas. Thanks again for your suggestion Warrtalon Here's to 11's on the stock turbo and 93 octane .

 

I know it's technically still 93octane, but you're using alky. That's not the same as just using pump gas, but people often refer to it as such. For example, last night, my buddy in an MR with the same mods as I have plus 272s ran 113.9mph on straight 93oct (no alky). That's what I consider going for 11s on the stock turbo and 93oct, but when you do it with 93oct+alky, it will still be an accomplishment. Hell, just trapping 115 means you have a daily-driven monster, imo.

 

every 1/10th in the 60ft is about 2/10's in the 1/4. when i had my talon i ran exactly 12.7 with a 1.7 60ft and 12.9 with a 1.8 60ft.

with the evo i ran 12.4@112 with a 1.87 60ft (5k rev limit and horrible traction) with ****ty shifitng also because of a unadjusted ACT clutch. I'm going back with the 5k rev limit removed and an exedy twin carbon. we'll see how it is now
