my tune could be stronger... 10.9 A:F with W/I; 17psi, 17 deg adv and tappered up to 8 deg split.
coolant started at 205F and ended at 210F
Air temp started at 116F and ended at 150F
datalog said 15.1s
can't say I'm too bummed, but after I install my EGT probe and refine my tune, I'll try again.

Welp, I gave this a shot last night...
17 seconds @ 10psi (creeping to 11psi)
Yeah, slow, I know... but I shifted early and slow at 7400 (doh!) and I was running super rich for some reason. Usually I log low-mid 11 AFR's and last night I was seeing 10.4-10.8.
I'd also be interested to see how much of an effect the pop-up head lights have on 40-140 times. I'll have to do a run in the day sometime.

As for me, i didnt do a 40 - 140, but i did log a 0 - 140. And according to that it took me 12.1 seconds to get to 140 from 0, and 2.2 seconds to get to 40 from 0. So that makes out to 9.9 seconds (damn i must be flying) I was also granny shifting. I cant wait to put this thing on the dyno this weekend.

Looking back at my datalogs I get 14.5 with an estimated 300rwhp (having run 12.4@115mph within 10mins of this datalog).
BNR Twins at 1.4bar on warped apex seals, shame I don't have any logs over this range when it was running properly as that should have been a couple of seconds quicker.

I'm making almost 300RWHP and I'm not a drag racer, but I'd love to know what my car might be capable of in the right hands.

gotta love my 'Lots O Boost' mod
I have a t78 and pretty much everything else you can think of to go with it except for any ignition amps. i have a street port, Microtech ecu with x4 ignition, water/meth injection. Eventually im gonna go with a little bigger of turbo, with some spray to spool it up, and either a large race port or bridge port.

A full weight FD making 260rwhp will run 13.0@110 with the same 60'

but I could have sworn I saw him do back to back 110mph runs and his slip definitely said that. Plus I watched his car on the dyno making 260rwhp running the same map (I know as I put it there 
). I'm fairly sure Dyno Dynamic horses are a little larger than those posted around here as we've never seen anything get even 390rwhp out of stock twins in the UK, even running a charge cooler for better pressure drop. RE:Worx's car has been safely in the 9s for a while with a good bit less than 600rwhp. All being equal using Lupe's power&weight numbers he should be running mid 9s with 150+mph terminals.

i guess its possible, when i dynoed at 244 rwhp i was trapping just over 107. I guess a better driver (i was 18 at the time) with a lil more power (possibly on a cooler day) could run 110 trap speeds.

took the car to the dyno, made 461 at the wheels at around 23 psi (fluctuating between 21 and 25) with the water/meth injection on and race fuel. The car wouldnt make any more power by turning the boost up any more due to a heavy fluctuation. Now if i can only get this fluctuation figured out.

greddy profec b spec II. I'll have to check them out when i get a chance. It only fluctuates in the higher boost ranges. If i just run off the wastegate spring it runs rock solid.

Yeah i know, because it doesnt take spool up time into consideration. Plus your already at traction if your car spins from a 40 roll. I figure i should probably add about a second onto my 9.9 number. So its probably around or just under 11 seconds or so. On the other hand, what do you think about that 7.1 second 0-100
