1/8 to 1/4 mile conversion?
Ok so I have ran at qualcomm several times which is a 1/8 mile strip but I want to know the covernsion equation from 1/8mile to 1/4.
This is my stats.
et-8.04
60ft-1.80
mph-88
is there anyway to convert this to an approximate 1/4mile time.
Btw, I have a evo 9 gg when I ran that time it only had a tbe, and a base flash.
This is my stats.

It always depends on how hard you pull in the back half, so there's no way to estimate, but since you're hitting 88mph in the 1/8th with a weak launch, you will likely hit 113-114 in the 1/4 and hit 12.3-12.4.
I'm basing this off my 7.76@88mph in the MR that ended up being 12.26@110.00. I had you beat badly at the 1/8th, but you would likely pull much harder on the top-end, which would allow you to catch up some, but probably not quite match 12.26. If you can get that launch down with that power, you could do a 12-flat in the 1/4...but you need to drive to a full drag strip at some point in time.

Not necessarily, since you don't have cams, but it is likely that you will. 89.5mph is freakin FLYING in the 1/4. I never did that much mph in the 1/8th unless I was on race gas. My only pump gas try with the mail-in Dynoflash was the 7.76@88.5 (12.26@110), and then my next run on race gas was 7.63@90.8 (12.000@113.7). Your 89.5 is very fast and is right between those two. However, on stock cams, you might only see 110-111 with less top-end than cammed Evos.

Now I ran it again on 110oct, tbe, base flash, 02housing, mbc, boosted at 1.60bar and finally got the slip down pat now.
Here are the stats
et-7.75
60ft-1.71
mph-90.5
This was when it was around 78degrees @ 10pm outside. Its been hot lately. I know its awd but just out of curiousity what tire pressure do you run and are you running on the stock tires cause I am?
Now I know cams arent out yet but is there anything else I can do to maximize the top end?

Wow, starting to get really fast now. The 90.5mph is getting close to 11s range. You got better with the 60', 1/8th and mph, so you're car is definitely fast. You see above that I did 7.63@90.8 on my best run ever, so you're not far off my 12.000 run. It's also possible that you will have more top-end than I did on that run, because my 1/4 mph was only 113.7. If you can trap 114-115, then 11s are closeby.
All my best times were on the stock Advans, and I was around 22-24psi to avoid spinning. You can probably turn the boost up to 1.7bar (24.5psi) next time. There's not much you can do for top-end without cams.

Now I plan on boosting to 1.72bar (25psi) when I get a chance to put the rest of my mods in. I still have to put the IC pipe kit and the mini battery kit and the ported coated manifold. After all this its time for the custom flash. However, I want to make a run before the flash and after the flash.
I wish I had a 1/4 track here, but for now I am going to have to rely on other peoples numbers to get an idea or estimation.
With the next set of mods and at 1.72bar I hope to see traps at around 94mph.
Wish me luck
. Hey warr someday with these basic mods maybe we could do a head to head sometime for fun. We basically will have similar setups.

I ran 12.1@111.5 in 95-degree weather with 80% humidity last August in southern MD, so I've dealt with my fair share of hot weather. I don't get that type of weather here in CO, but the altitude is far more damaging to power than hot weather.
Skilmatic, we'll never be similar, because I don't have a IX. IXs are much faster, especially with mods. I wouldn't put 94mph as your goal, because that is highly unlikely. 92mph in the 1/8th would be a good goal. At that point, you'd have gone faster than I ever have in my Evo, which was 91.3mph in the 1/8th.
