VTEC just kicked in yo

[LeftVentricle]

Midnight Mayhem at The Strip at Las Vegas Motor Speedway. Hopefully I can improve my woeful mid-eighteen time. Going tonight. I don't have a scanner or camera, so I won't be able to post the slip.

[LeftVentricle]

Terrible. Only improved by like five hundredths.

[robertisaar]

for a 3.1 wagon, thats probably not all that unbelievable. was the wife with you that time?

[LeftVentricle]

No, and I had less fuel on board. It's very possible now that the engine has lost some power, but I don't see how. It was rebuilt like 40k ago.

What kind of times are you expecting?

With less than 100 WHP and a heavy wagon mid 18's are about right...

[montess408]

is the motor stock ? i think your gonna need some big mods to move that heavy car!

[1QUICKHATCH]

What altitude are you running at? My lunina is the same weight if not more, and it started at a 17.5 before swapping for a high flow muffler. My mom had a 90 cleb. Wagon with well over 300,000kms on it and it felt faster than my lumina dose. Do you have a caliper hanging up or a pluged fuel filter or something?

[LeftVentricle]

The engine is supposedly a 3.1 MFI. I replaced the fuel filter probably about two years ago, maybe I should do that...

I'm not sure what the altitude is at the track. Maybe 2300'? Las Vegas is around that.

As far as brakes go, I doubt it. Calipers were replaced about a year and a half ago, and the car doesn't sit long enough for them to stick.

I don't get why everyone keeps saying my car is heavy. It's maybe 150 lbs heavier than a sedan. According to these two sites, curb weight is 2971 lbs for a '90, and there shouldn't be much difference for an '89. It's not like this is a V6 Caprice.

[montess408]

yeah i guess it's not that heavy.(not as bad as a v6 caprice lol) and i was looking for the lumina weight too and they are 3400+ and the guy on top said he is running faster then you are. is it possible that aerodynamics are playing that big of a factor ??

[LeftVentricle]

There's some power loss somewhere. Perhaps compression? Aero might be it, but I've heard of 2.8 sedans running high 16s, and they're identical body-wise aside from the expanded interior. And I don't think the roof rack would account for that much time loss.

no, but it is ugly... might as well yank it off for "better fuel economy"

[1QUICKHATCH]

If you are at 2000+feet I can see that being some of the diference, I am around 6-700ft. What transmission do you have? If you have the 3spd like me leave it in 2nd and wind it out! Do you have a tach in the car at all?

[Superdave]

2971 lbs with 100 WHP equates to a 18.04 in a perfect world.

What is the final drive and are you sporting a 3T40 or 4T60? I know the A body didn't get a 3.33 FDR like the lumina.

I have the 4T60, and according to my SPID tag it has the GX3 option. Alldata identifies that as 3.33 final drive.

2971 lbs with 100 WHP equates to a 18.04 in a perfect world.

And with 95 like I have it's 18.35, so I'm basically dead on. Strangely, it says if you have 140 crank hp, a theoretical 16.99 is your time. So I've lost 31% of the original power somewhere. I need to channel Tim Taylor and add MORE POWER!!!!1!!

Speaking of, what differences are there between gen2 and gen 3 engine blocks?

Do you have a tach in the car at all?

Not from the factory. To my knowledge, only the super rare Eurosport VRs had a tachometer as an option. I've been meaning to get one anyway.
