96' bonneville ran 16.9@83 mph
yea my 95 should be around 15.7 in the 1/4 with just a CAI and Muffler. So something is definently wrong. I know the 1995 is without a doubt the fastest stock for stock between 95-03, but i would think the 96 would be close. I ran up agaisnt a 2002 ( i believe and put bus lengths on him in the 1/4), the videos are on streetfire (just go there and search "1995 bonneville". I have quite a few videos you can take a look at.

The 2.84 is a wee bit tall...
Fantastic 88, Even my 91 LE with granny gears is ok... It takes off fine and its funny seeing the tach below 2000 rpms at highway speeds... Nets some good MPG'* too

I took some video of exactly how slow his car is. It'* painful. There is no bottom end what-so-ever. From 50-70 didn't seem so bad, but I could run faster 0-30mph.
His speedometer is also way off and reads too high. He'* got Grand Am GT wheels and tires on it and they're smaller than his stock tires. On the highway, I was doing 80 mph and he said his speedo read 100 mph. We didn't really plan that, so I'm not sure if we were going the same speed, but I know his speedometer '* way off. I think, at about 40 mph, his spedometer reads 50mph, so adjust your sence of speed when watching the videos.
Launching it from 50 mph:
Launch to 50 mph
From about 3 mph to 70 mph:
Slow Roll Up to 70 mph
OK, he'* got P225/50R16 on it, and I believe stock was P215/65R15. Looking at the specs of each tire, stock is 26.0 inches tall and his Grand Am tires are 24.9 inches tall, so that'* a big differance. I figures the speedo should read 8% high, and he'* said it always read about 5 mph high from the factory, so it'* about 10 mph off at 50 mph.
I'll try to run a can of sea foam through his engine as soon as I can, but that probably won't be until this weekend (if that). I wanted to do it last weekend, but he forgot to tell me he'* going to Michigan, so he'll get back Tuesday night.
I was thinking, at least his car sounds good! Oh well, maybe he should just send his piece of crap car to the junk yard and buy an SSEi.

I would suggest getting the speed calibrated. Also, the L36 is not exactly a slouch, it'* just that the speed you can go is directly proportional to the amount of money you want to spend.

Here are some videos of when we went to the track. It'* pretty sad, really.
Here'* an attempt to do a burnout in the water box. It didn't trun out too well. He said he put the e-brake on and floored it.
Burnout Attampt
Here'* him racing my other friend'* L67 LSS. His Bonneville ran a 17.5. The LSS ran 15.5. Both slower than they should be, but I've ran a 15.06 in the Olds.
Supercharged LSS vs Bonneville SE
Notice how long it takes for the Bonneville'* time to post because he was so far behind.

I'm going to suggest making a heat shield for the filter to keep the hot air out that will kill performance. If he cant afford to have the speedo calibrated then he should have stayed with the proper sized tires not having the speedo set right.

Its strange, My LN3 seems like it has almost as much for guts but I'm missing 40 Hp too...
There is a lot that can be explained in theroy as to how the motors differ when producing torque...
The LN3 in my 91 Is a low end torquer great for puttering around town and crawling hills with TCC lockup...
The torque peak of the LN3 is 220 @ 2800 Rpms..
The L36 is 230 @ 4000 rpms ... Above 1000 Rpms( closer to 1500 ) the L36 should produce 200 Ft Lbs.... But 3000+ seems to be a sweet spot for the motor...
The LN3 has most of its torque off the line... Makes it an easy driver in town... Easy to run around with 2500 Rpms shifts...
Your friends car seems to pull good once it gets into the midrange...
He has the 2.84 gearing... A handfull of us have the 3.06 That .22 does make a good diffrence...
Another off the wall question, has the trans ever been replaced on his car?
