nice build. how much do you think you car weighs?

I've been kicking myself for not getting it on a scale this last weekend. The car itself is lighter than stock due to the aluminum heads, fiberglass bumpers, no heat or ac, swaybar removal, lighter wheels and tires, aluminum shocks, and a few more tiny things. Has the stock aluminum hood. The 4L80e is a bit heavier than stock and the rear swaybar is a good bit heavier than anything stock.

I'm 360lbs, so that doesn't help. I bet race weight with 1/2 tank is somewhere around 3,500lbs. With a trap of 119.6, that puts me somewhere near 470-480 rwhp which isn't too unrealistic. I need to pull another 100lbs out of the car before I put a cage in it. Will probably do the trunklid in fiberglass, the windows in thick lexan, aluminum race seats and a fiberglass dash when that time comes.

Very nice. looking forward to reading about your time slip when you put the looser converter in. Love how the exhaust sounds by the way.

Great build! Very cool seeing another NW Cutlass. I had my '79 down at Woodburn on Friday. You've only got about 6.5 seconds on me.😵

After a long discussion with many people, including those that aren't in my head, it was decided to run a 100-150 wet shot of nitrous instead of doing the converter. Bottle is installed, solenoids are installed. Plumbing the lines for fuel and from bottle to solenoid tomorrow. Get it wired before the weekend because I'm doing a two day track rental with a street car group up here in Washington. ALSO, I went back to a MAF tune and installed a LS7 card-style MAF in my cold air intake. Low end and part throttle response is much improved and the tune isn't drifting nearly as bad as the SD tune did with changes in weather. I'll get pictures of all of this junk soon.

I participated in the Northwest Nights Motorsports track event at Bremerton Motorsports Park this weekend. Pulled into the pits late Friday night and set up camp. It was cold. Here's some views of the morning.

And my camp.

Ran close to my best on Saturday, but only got two runs in. I was concentrating on getting my nitrous system wired and functional and logging the runs to verify the tune.

Sunday morning:

It was slippery!

Pedal, pedal, pedal....

The important part- it all came together in the end and I ran a 10.98 on a 100 shot.

And a snapshot of the log of that run.
