Well I had my Evo for more then a year now and I finally made to E-town. I am not really into drag racing, I just wanted to see what I can do. I had my car custom tuned by Shiv, which put down 331whp on a dynojet. I am running basically Vishnu Stage 1++. I made three runs and here is breakdown of my best run:

Temp: 87
Humidity: 57

60' ... 1.984
330 ... 5.558
1/8 ... 8.540
MPH ... 84.78
1000 ... 11.096
1/4 ... 13.218
MPH ... 105.18

Just to note I was not trying to launch the car hard. My best 60' was 1.984, in which I was quick slipping at about 3-4k rpm. I also added about 4 gallons 116 fuel to my 93 which I had about 3-4 gallons left in the tank (I was not running a race gas map). I just wanted to make sure the car ran cool.

Couple questions, how does my MPH look for my horsepower? I know that I could of cut a better 60' time but I really don't want to abuse the car. Also I think I could of shifted faster but it was pretty smooth all the way down the track. Overall I happy, the car ran well and I know if I practiced that I could ran in the 12s.

 

330whp you should be in the 107-109 range

 

OUCH on the 60ft but I ran 12.7@ 107 and 12.5 at 108 IF you launch hard you will probally be like 12.5 or so... with the RACE gas you should of had like 25PSI!

 

Like I said regarding the 60' times the best I was looking to do is like 1.9 or 1.8 I just didn't want to abuse the clutch or the transfer case, so my launches were not that hard. Maybe because of the heat the MPH were that there, because all three of my runs I hit 105.

 

Honestly, the mph is awfully low. 05s do 104-105mph in stock form with only 240-250whp. At 330whp + race gas mix, I would expect no less than 110mph. 60' affects ET, which partially accounts for the 13.2, but poor launches don't negatively affect mph. Shifting is another story...if you weren't going to 7400-7500 in almost every gear before shifting, then that would partially explain the low mph.

Temp and humidity were working against you, but it looks like you did very little in 4th gear. Your 84.78 in the 1/8th is decent, but you only gained 20.4mph in the back 1/8th, which is all 4th gear, so that doesn't seem right. Did you shift to 5th? If so, that would explain pretty much everything. Btw, what do you do with 330whp if you don't drive the car hard? I'm not saying you have to go dragging the hell out of it, but you don't get the most out of the car unless you rev high and shift quickly, especially with cams. If you're going to take the time and money to test'n'tune, you might as well take the opportunity to drive the car to its fullest. You do it 3 times, hope for one really good run, and then go back to driving normally. Going to the track and intentionally driving it weakly doesn't give you an accurate idea of what your car is capable of. Yeah, you dyno'd some nice numbers, but it seems you were looking to verify it in a real-life situation.

Btw, I ran about 8 1/8th-mile runs today all with hard launches on the stock clutch while shifting near redline in each gear and while crossing the finish line while bouncing off the rev limiter in 3rd. Is this recommended on any sort of regular basis? Hell no! But if I'm going to test'n'tune, I'm going to drive ***** to the wall until I'm finished for the night...

 

The slow 60 will hurt your traps. I rev to 5000 rpm and do a slow slip until the clutch grabs, then quickly slip it. I've got over 40k miles and probably 30 or so runs and no issues. I get 1.70s all the time. I would also look at a race gas map.

 

Sorry, but this is incorrect. Slow launch equals less mph at 60 and less at the end of the track. Think about it. Maybe you are thinking reaction time.

 

Regarding the shifting I did shift everytime around 7400-7500 in every gear. I didn't have shift to fifth. I would say by the end of 1/4 mile I am at about 6500 rpm in fourth.

 

Nah, a slow 60' (like 1.9) doesn't hurt your mph...in fact, you can sometimes get a higher mph, since a great launch lowers your ET, which gives you less time to reach higher mph before the finish line. It's counter-intuitive, but true. Think about FWD cars like the SRT-4. They spin like crazy en route to 2.4 60' times, then hit high mph, but if they throw on slicks, they cut half a second, but run a slower mph than before.

 

Interesting...I'm not sure why 4th was so slow then. I picked up 22mph (84-106) with just an S-AFC, but I was over 7k when I hit the traps. I do have a 6 speed, though, so my 4th doesn't go quite as far.

 

But this isn't a traction issue. This is about babying the car. I agree with your example above, but that isn't analogous to the discussion. If you ease into the launch, your mph will be lower. That is why imexperienced people improve 60 ft, 1/4 time and mph as they learn to launch their awd car. We've all seen it. I run 12.45 at 110 with the exact same mods that I ran 13.2 at 104 when I was learning to drag the EVO.

 

Honestly the only thing that kind upset me was the MPH because there was another EVO with a full exhaust and boost controller, he was trapping the times as me. Maybe its my shifting, the car seems to run pretty strong it pulls hard. I did couple pulls with a Vette probably an 03 I slighty modded, I was right next to him he was not pulling, to bad I forgot what he ran at the track.

 

I have 8 timeslips in my hand from today that say otherwise:

On my worst launch (1.955 60'), I ran 84.08mph.
On my 2nd worst launch (1.939 60'), I ran my highest mph of the night - 84.24.
On my 2 best launches without shifting to 4th (1.85 60'), I ran 83.83 and 83.79.

The 2 lower mph runs were lower ETs than the higher mph runs due to the 60'.

My 2 lowest ETs of the day came when I shifted to 4th around 7300, but my mph suffered accordingly.

 

I haven't ever seen a dramatic difference like that just from learning to launch. His 60' times were only half a second slower than my bad launches today, and I still got my highest mph's of the day. He can't get a 1.9x by going slowly. My 1.9x's were poor launches, but I was still hauling *** (no spin, slight bog).

 

You're confusing your situation with his. Please understand that I am in no way saying that you can't run higher mph with slower 60 ft times. Clearly this is possible and happens frequently. I have 3 time slips that show a higher mph with a quicker et and 60 ft. This doesn't make me right any more than your time slips make you right.

Think about it. He eases the launch. Clearly, a harder launch and he could improve his 60, 1/4 et and mph. We all did it as we learned to launch an awd car.
