Default Track time guesses...

Here's something to throw you guys off a bit. It's still an F-body though! Anyone think they can guess what my track times would be? To me it feels like 16s but LS1 guys that ride with me say it's faster than they thought... Dyno sheet from JBA Performance in San Diego.

Applicable specs:
1999 3.8L V6 Firebird hardtop
4L60E that throws P1870 codes every couple months
GU6/G80 (3.42 gears and a Torsen LSD - factory)
124k miles

Applicable mods:
Whisper lid
K&N filters (air/oil)
LS1 aluminum driveshaft (stock was a 1-piece steel like LT1s)
Stock 02 WS6 muffler-back
High-flow cat
UMI non-adjustable PHB
!spare
!jack
!rear seats
Chrome LS1 Firehawk wheels (275/40/17) Nitto 555 front, 555R rear
I throw on the stock 16" twisted 5-spoke TA wheels with Riken tires every once in a while (track days, road trips).

And the not-so-helpful mods:
32/19 OEM swaybars w/poly bushings
KYB AGX shocks front (stock springs)
Bilstein HD shocks rear (stock springs)
About 10-15 lbs of sound deadening (just did the doors).

The Firehawk wheels make a noticable detraction from acceleration, especially from a dig.

Considering a stock Y87 V6 F-body can run low-mid 15s, I'd say the OP has enough to make it into the 14s.

The last two times I raced on a prepped course, it was over 105 degrees outside. I think I'll stick to cool weather from now on.

The answer is: To have fun.

People with 9s cars think 11/12s cars are boring. But is there anybody here that would turn down a C5 Z06? Or an '03 Cobra? A high 14s/low 15s car is still "quick." Nothing to be ashamed of, as long as you know where you stand on the totem pole.

Is it really "fun" to spend thousands of dollars and/or hundreds of hours working on a car and then only getting to drive it a total of 20 seconds a week? For some people it might be. I'll pass on that one, thanks. I tried to get a TA (found a nice LT1) but my parents wouldn't let me. So, I got the quickest V6 I could find (hardtop Y87). Looked into F-bodies because stock for stock, they were the quickest cars with the best MPG and most storage capacity for the least amount of money.

I like to think my car is fun to drive, especially in canyon runs where 1/4 mile time is less important than maintaining speed. 3 point subframe connectors are going on along with sticky tires on the Firehawk wheels pretty soon. Probably will increase the 1/4-1/8 time but also increase corner-carving ability. I also use the recommended alignment settings for autocross, instead of stock (which feels tankish, TBH). I already had one local guy challenge me to a canyon run with his V8 car...

Yep, people get jaded. I love when I can drive my uncles ~420hp Nova, but it's always down for repairs for most of the year. He's always drunk on my birthdays and his car is always running by then, so I always get to drive. When I go cruising with guys from Tech I try to stay near the back of the pack so as to not **** anybody off with my 118MPH speed limiter... LOL

Nope. I've had some people with untrained eyes that refer to my car as a Camaro becaue they don't know any better.

People in general are dumb. But many people could mistake his car for a Formula, since it looks identical to a regular Firebird. And people complain that all Mustangs look alike

not by today's standards..check the back of a Motortrend. Most of the cars are atleast running 15s. That would make them avg (normal)..not quick

If you're at a decent track with decent weather, no reason you shouldn't be running low 15s or maybe a high 14. My Formula 305 TBI A4 with headers/exhaust ran a 15.79 at a mediocre track and you should walk all OVER that car without any kind of issue. Shoot for a 14.99.
