Post Your 1/4 Times And Mods.

[Jake whitebird]

Jealous!! That's only a 1/4 mile above sea level! My 10.5 was on a street tire, gonna go Wednesday and try -2 +9 with this shinko hook up pro, but also bring my 43t and 45t.

What is your altitude?

 

[Jake whitebird]

Yep, 5280 at bandimere speedway and I think the hot weather it turns it into like 7700 or something. Just kills any power up here

I have some friends that race up there and they do complain how much their bikes slow down. Last weekend we were at 4400 feet with 78% humidity and my bike was slow. I can't imagine 7700

Wondering a question about how the tune relates to MPH in the 1/4. If around sea level stock motor with full exhaust, trapping 149-150 would you say there is room in the tune or that's basically where supposed to be? I'm terrible at launching (minimal seat time @ strip) but I'm always 149-150. when its like 75-80 outside. Curious if I should go get my tune dialed in again or prob not with the money. (its an internet tune from a bike with same exhaust roughly same elevation).

 

[Dennis]

That MPH would be ok depending on total weight and other mods. Need to know more about the bike and about the air. If you are at 2500 DA and total weight is 725 then 149-150 on a stock Gen2 with exhaust is about right.

 

[04LE]

Just a guess from looking online I think the DA would have been around 1900-2000. I weight probably 185 suited up. Only weight reduction on bike is the exhaust.

 

[Dennis]

You might find one, maybe two mph more in it as you get better at the launch in those conditions. 151 would be pretty solid.

My best so far is a 9.58, with a 60 foot of 1.6, at 149 gen 1 2005 with 6 over and some little motor work. Cams and a port job. I have a air shifter. I have been having issues with my air shifter and missing shifts. I made 185/190 hp. Front strapped/ tiger pail power commander 3.
***Goal is to get to a 8.9. I weigh 170 withput a suit. Bike is setup for street/strip. Have r1 rims to put on. I live in caifornia and it geta nasty hot so not sure if a rider mod will get me to a 8.9 but i am foing to try. Old thread but wanted to add to it!!!
-Also my front sprocket is 1 down and back is a 42 With the r1 rims im going to a 16/44

Da might play a big part for you. If the da is high it will make it hard for you to hit that goal. If it's low you should be able to hit it if you change your gearing get some low 1.4 60 foots. Your goal is to be off the clutch by the time you get to the tree.

So how much does the DA affect a bike? How much time will it eat up if its bad??

 

[Jake whitebird]

Well, consider a stockish busa can do... 8s? At sea level. Bring it up here to Bandimere 5280’ plus DA, bike could run a 10

 

[Jeremy Godo]

Guess I will need to add more power for California living then and get that launch down. Im at 4750 DA.

 

[ItsDooomz]

Don't confuse elevation and density altitude. They are very different. I live at sea level. I've seen DA 700 feet below sea level and 2800 feet above sea level.

doom... I think ure operating at a level most people don't understand.... can u elaborate what constitutes DA and how big of an impact it can have on Ets? some people think it can add 70 Hp to their bike...…… is this misleading? I look forward to ure response... and I think most men are afraid to ask because it makes them look stupid... thankfully I was born without this gene, as u must know by now.

 

[Dennis]

2008, 1441, 80 hp nitrous, almost 70", full street attire (but not really an every day bike). I need to work on the 60' and shooting for 7.69 and 180 mph this fall.

 

[busakiller]

Very nice dennis. Wish I could get those kind of 60 foots.
