Have you ever considered a '96-'97 Bonneville SE supercharged? My dad has a [black] one and it has a lot of neat pluses:
1.) Weighs only "3550 lbs." (3710 lbs. with me in it and all reservoirs at full including fuel). My dad got the minimum model ("SE") and the minimum options ("SLE option pkg" and nothing else). Hence it's a hardtop sleeper/manual passenger seat/6-way power driver seat.
2.) It looks like a rental which makes it more of a sleeper (beat friends in '96 Mustangs, '97 Eclipse GSX turbo with off-road pipe, HKS exhaust, and intake mod, and '92 MR2 Turbo all with extreme ease).
3.) Less restrictive appearing large volume intake box (devoid of sharp turn in/out of the airbox seen in Regal GS and GTPs) and devoid of the U-bends seen in some of the other L67 powered cars.
4.) Rare as heck. Base Bonnevilles were avail. with supercharged engine options only in 1995-1997. 1995 had 225 hp and the Eaton M62. 1996 and 1997 had the Eaton M90s and 240 hp. The 1997s also had the quieter 4T65-Es (with higher shiftpoints?) and access to aftermarket tuning is more widely available. These base model supercharged models were unpopular and the day we took delivery, the salespeople not directly involved with the deal were scratching their heads why our lightly optioned S/C SE Bonneville was less $$$ than N/A SE Bonnevilles laden with 12-way seats/moonroof/computer command ride, etc. and far less than SSEis. I only saw one 1995 on the road. I saw a 1996 advertised in the paper at a dealer clearance sale. And that's it!!! I won't be surprised if less than 300 1996-1997 L67 SE Bonnevilles were ever made. These cars also have traction control not avail. on early '97 GTPs and the traction control is tremendous with amazingly fast action in slippery surfaces (doesn't kill the car's power with slow recovery of power like some other traction control systems).
5.) Rear suspension has damper and spring on different axis. Hence I fitted $60 AirLift airbags and pumped them up to 35 psi at the strip and down to 3 psi on the street. That cannot be done on Regal GS and GTPs (unless somehow you have a donut shaped sleeve/airbag around the damper like some import applications). Allows consistent 2.13-2.14 sec. 60 foots on majorly crappy for drag racing Eagle GAs.
Results (100% stock right down to paper filter)
Best 1/4 mile: 14.525 @ 94.06 mph (half dozen or more timeslips in 14.5s). Done in 60 deg. F air and good baro. and full tank of 93.
Best trap speed: 94.7 mph (41 deg. F air) on pump 93/ 96.2 mph with race gas and propylene oxide mix
1/4 mile time in 78 deg. F muggy air: 14.84 @ 91.8 mph and tight new engine
Best 60 foot: 2.09 on Eagle GAs
All this with stock shiftpoint of 5200-5400 rpm!!!!!
Now I think with K&N drop-in filter, stickier Yokohamas AVS dB radials, and Castrol Syntec transfluid it should run 14.4s on a cool night. Torque convertor stalls at 3200 rpm indicated!!!
Post your E-mail and I'll send you a pic of the car (not for sale, but you can get an idea of what I mean).
