7500rpm for my 12.1 pass. I shifted into 2nd at 7200 and 7500 for all other gears but it slowed me down to 12.2 with the same 113 mph. This is all on my stock clutch still with 33k miles on it. I have launched on it around 30 times. I am very surprised. I have a twin disk waiting but not till my stock on goes.

Im going back Oct 2nd with a fresh set of plugs, oil and 20lbs lighter. I think my meth mix was off also so I will make sure its a 50/50 mix this time. It also should be cooler outside. Hopefully this gets me into the 11s

I am reading your post and am confused. Shift points should be around 7200 1-2-3 and fourth you run out and dont shift to 5th. I leave the line at 6400 and the rpms drop slightly but shoot towards 7200 quickly. Thats why the 1-2 is the most difficult. Basically before the clutch is all the way out it, it goes back in
I dont know what the lowest is you'll see in rpms but it isn't much lower than the 6400. I try to make it so it never drops or drops minimally.

My 1/8 is 7.6 @ 86 ~ 88mph is that where it should be?
My fastest time so far and this was with taking the wing off
60' 1.643
330 4.940
1/8 7.679
mph 87.53
1000 10.038
1/4 11.997
mph 118.85
On this run I was set to 5900 cause I was spinning at 6400 and it dropped to 3468 rpms

I was going back and looking at this and regardless if I launch at 5900 or 6400 I can get a 1.62~1.65 60' but my rpms are still dropping under 4k in 1st gear.

Almost any 350-360whp DJ full weight Evo I know locally run 112-113's all day. 350-360whp is your average pump gas,bolt-ons power level these days so its rather common. Weather plays a big role on how much power you're actually putting down on that particular day. Can definitely swing your MPH a full 1 MPH at times. Especially with the crazy track weather that occured during the DSM shootout and the Englishtown Showdown this year!
