Default How'* 10.1 in the 1/8 for a L27?

Hi all,
I took my 1994 SLE to Grove Creek last night. It definitely wasn't running it'* best, but it was above average. I made 9 runs. I had removed my Superchip last week along with the 180* t-stat to check the changes in my gas mileage (up 3 mpg runing stock).
Temps were right around 65-70*F all night and it was humid (but not too bad).
My reaction times were horrible. I couldn't seem to get below .602 (ok, it was my first time to the track this year where last year I had it down to .505 -.520).
My 60' times were good, but it was about the time I'd hit 2nd it'd bog and just seemed like the power was not there (I think'* it'* my alternator as my digital voltage guage was usually showing 12.5-13.1 in the higher rpms).
Wheel-spin wasn't too bad so traction right now isn't a big concern (for improving -although I could use a couple windshield-urethane filled motor mounts to hold the engine a little more solid for more power transfer).
My best 60' time was a 2.148 and my worst was a 2.353. I had the best 60' foot times of any street vehicle there including the 2 Jeep Grand Cherokee 5.9 Limiteds 2.19'* (9.91 @ 75). Even the 1993 LT1 Z28 (CAI and NGK iridiums were his only mods) was only hitting 2.23'* (9.42 @ 79.3mph)
My best time in the 660' (1/ was a 10.124 and my worst was 10.502.
My trap speeds were between 68.98 - 71.21.
And this was with the car fully loaded (full stereo consisting of cd deck, cd changer, 13 speakers, back seat, floormats, all the junk under the seats, 200 cds in jewels cases, and all the dirt on the floors).
All I did for race prep was get two bags of ice to cool the intake manifold and CAI piping and was running 91 octane from SA and removed the rubber from the front of the hood and at the rear of hood for more cool air coming in and more hot air going out of under the hood.
Anyhow, I feel the car is capable of dropping 1/10 as is if it would run good and the timing wasn't retarding so much about the time I hit 2nd and maybe another 2-3/10'* once stripped down.
What are your takes on this? Doing the these times calculate into low-mid 15'*. Better (15.0??) when running proper and when stripped of cargo.

Of all the car'* I raced (8 different cars) I was beat only by the 1993 Z28 and the 5.9 Limited (I only raced 1 of the 2 there).
I raced @ beat:
1985 Camaro (Edelbrock carb, breather, and flowmaster exhaust)
Jeep Grand Cherokee Limited 5.2 -10.5 @ 68 (stock)
Jeep Grand Cherokee Laredo 5.2 -10.2 @ 70 (Flowmaster exhaust, and K&N CAI -these two mods netted him 3/10'* @ 2mph over stock in the 1/8 and at the end he was reallygetting into his power area so the in the 1/4 he probably would've had me by 1/10)
Mid-80'* Caprice 10.3 @ 69 (350 with Dynamax mufflers, carb, breather, MSD Blaster 2 coil and wires, NGK plugs)
1995 Beretta 3.1 11.2 @62 (stock)
1992-3 Ford Explorer 4.0 11.0 @ 65 (guessing stock)
1979 Corvette 350 10.4 @68 (Magnaflow muffler, and a K&N air breather).

My best run was the 10.124 @ 71.21.
In all the runs I kept the shifter in 1st until I was past the traps since it always shifts to second on it'* own at 44-46mph (56-5700rpm'*)
How do any of you who are regulars at the strip think I am doing (I'm not the fastest thing out there for sure, but for a L27 NA'ed Bonneville I'm guessing ok)?
How does this compare to a Series 1 L67?
I haven't been able to get my sister to race me lately (she'* been having some problems lately with her 1995 L67 Riviera so I'm not pushing her), and I'm never around when dad'* driving my mom'* 1992 Park Avenue Ultra L67 (has 198,000 unrebuilt, untouched miles with the original supercharger working smoothly).

I plan on going again in a couple weeks and my cousin wants to drive his wifes 1997 Grand Prix GT there to check that out ( and to see how much difference a K&N drop-in makes versus a stock FRAM).

Seems like pretty good times to me for a non supercharged Bonne.
I have never raced my Bonne in the 1/8 but I have raced my Firebird which is a bit faster than my SSEi. I can't seem to get better than 2.1 sec 60 foot times on street radials with the Firebird posting a 9.0 time in the 1/8.

Grove Creek is about 15-20 miles west of Dassel/Cokato on HWY 12.
It'* only $20 to run.
What'* required to run:

Battery hold down in place
Battery connections tight
No major leaks
Helmet
Seat Belt on
Windows up

I don't know when the next time will be that I go, but I will try and PM or e-mail you a couple days in advance. Would be sweet to have another Bonneville/3800 car there.
Maybe we'll have to have a meet there for the Minnesota Bonneville club.

I'm surprised you need a helmet for 1/8 mi.
We only have NHRA sanctioned races a few times a year here cause it'* a small town and they use the local airstrip that is only long enough to run 1/8 mi events and we don't need helmets.
There are 1/4 mi events held at the larger cities but they are a days drive away and with Ferry travel and hotel costs it is prohibitive, so I don't go as often.

I wish I could tell, you but the track was only 1/8 mile. Going by the 1.55 (or maybe it'* 1.57) x 10.1 = 15.6 - 15.8 roughly for the 1/4 times.
I am guessing that if I totally gut the trunk and back seat and all my stereo equipment, and get my superchip in and put the 180* t-stat back in I would probably be in the 9.6-9.8 time in the 1/8 and 14.9-15.2 in the 1/4.

BTW, does anyone have the link to the website with the factory accelleration specs for all cars? I would really like to see how my car with 187,100 miles with mods compares to what it was new.
Also, what times are other L27/L36 cars running in the 1/8-1/4? Would be interesting to see how I'm doing compared to other cars.

Hey Willwren, it would be cool to have a page on this forum where we can go to list our times (I know the Shelby-Dodge club has one and it really helps to see what other people are running). We could make it so it says:

Name Year/Make/Model Engine 1/8 or 1/4 Time Trap Speed Mods Track


Just a thought
TIA,
Stylez

not bad at all for a NA car. there was a guy at the track this past sat. that had a 93 bonneville NA. he ran a 16.59 1/4 mile. i told him to take his LF headlight out and he ran a 16.50 next. it was like 80* with 51% humidity. i know with my car on street tires, i spin off the line and have to use TC or my 60' time will be real bad at the track. with the heat and humidity, i had a 14.73 1/4 with a 9.41 1/8th, but my 60' was like 2.19. that run the my TC hit 2 times off the line. i really need to get some drag radials.
