Default 1/4 Mile Times For SC300/400's

First off, I give my sincere apology if there is a thread like this. Despite my several searches in Google looking for a list (and on here), I can't find one.

Do we have a master list of SC300/400's, mods, 1/4 mile times and dyno numbers (optional). If not, can we create one?

Main purpose being that it might give people a good idea of what to expect or what they need to do to achieve a certain time. After some search, readings and videos, I know I've tuned my expectations down just a tad. Getting these land yachts down the track at decent times (with full or near full interiors) is a litter harder than I though!

SC400 is like.... 15.slow, and the SC300 is 15.a little slower. Mid 15's is my best guess.

I figured that for stock cars.

I was hoping to get the numbers on some modified cars.

This last fall - I did a quick Dyno and took the car to the drag strip -
222rwhp - first 2 runs were at stock Boost Levels (~10psi)
299rwhp - one run at 17psi
239rwhp - (I was an idiot and the car downshifted into second) so we stopped that run -
266rwhp - one run at 14psi

Ill find the whole file later to look at.. but the 299hp shows my first indication of misfire issues (peaks and valleys like the Colorado mountain range)
When I ran at the Drag Strip a week later.. I could not run at 17psi - the misfiring was severe enough that anything above 13psi caused issues -
I was Running consistantly 14.3 at ~12psi The lowest I ran was 14.0
I have to learn to control the wheel spin at launch and first to second gear - definitely needed better tires -

'93 Soarer - Automatic btw
275/40R17 Tires in back - /w LSD
Greddy EMU and Profec OLED boost controller -
Map was 'stock' minus the "boost cut" being eliminated.
DeCatted and 3" to 2 x 2.5" for exhaust.

----
side note.. In Denver CO two summers ago, everything on my car was stock and I ran a 13.9 - may have been luck or something...
but that aside - two friends with their EVO X MR's were running 13.4 and 13.6 that same day - on the highway/street our cars are/were equal (Minus the first 60 feet) - I'd always have better top end and pass them by 120kph with ease.. so im GUESSING that if the car was running properly it would be around the same mid 13s - but that waits to be seen now that ive replaced the coil packs among a few other things and the misfiring is gone.

Was this on stock twins? I'm actually running a Soarer 1JZ in my SC300, single turbo though with some supporting mods. I'm actually after a EMU since I happen to be auto as well! I'm at around 8-9psi right now though, but the car pulls pretty good for it. A lot harder than my 2g DSM did at 15psi, thats for sure.

Good info so far, looking to get more!

GREATLY appreciated. I've only played with these things very minimal, but want to learn.

I'll definitely need a good map to start with.
