You said that you were looking at the ZZP SS Supercharger kit. . . . . . . Just for a FWI Jackie from ZZP did a 12.9 @ like 104 in a '97 GT with a ZZP Intercooler, SS M90 Supercharger Kit, GTP Throttle Body, U-Bend Delete, 3.0 Pulley, WP Pulley, DHP 1.0
With half of those mods you could be in the 13'*. You add some rockers to that list and there is a good chance you are going to be in the high 12'*.

True . . . . . but most just get fed up and slap on the F/I then blow past the 13'*. . . . .

I'm with ya on this one brother. There'* just something inside me that won't let me go the same route that everyone else takes. There hasn't even been that much research into the world of the N/A 3800. ZZP and INTENSE have done pretty well, but I feel there'* a long way to go with this motor.

Personally, I'd rather spend $10,000 on an N/A car that makes 350hp than $5,000 on a F/I motor that makes 450hp. Call me stupid, but it'* where my heart is.

Cue the music! ...."I gotta be meeeeee, I gotta be meeeeeee"

Actually 4v per cyl heads could be developed. The Valvetrains are both run from a single intake, an a single exhaust pushrod., there are some very pricey SBC heads available like this now. Possible? Yes, worth it? No. The cost is more then enough to scare off anyone though. Especially bonneville owners, who generally aren't as nuts about speed as GP guys.

With an N/A H body you'd need atleast 300 hp, if not more to get into 13'*. The biggest restriction IMO? The Intake Plenum. It'* made for lower RPM torque, and not upper rpm powerbands. The bonnie can hang with a lot of cars off the line, but just falls off above 3500-4000 RPMs. That'* where you need to pickup the most ground. Custom manifolds wouldn't be cheap either.

Turbo'* tempting but I hate that damn plastic upper intake.

1 of the reasons I want a supercharger is to eliminate that concern forever.

Is there some special upper intake that doesnt crack?

There are aluminum intakes available for our motor (namely from the rwd applications such as the f-bodies)

You can also convert to the newer Series III aluminum intake.

how many miles are on your car? Mine went at 130k (90% highway) in a really bad way by dumping all my coolant into the engine and overheating the car. If you are around 100k, just get a dorman intake and you will be set for the rest of the life of the car. You are talkin about maybe $500 tops.

Mine failed on me at 80,000 miles

Pontiac Dealership fixed it for 700$

Im at 129,000 miles now.

I just hate knowing that its a sure thing that peice of ***** going to craxk again if I dont do something about it.

Sadly its one of the reasons I want a supercharger. Too not worry about it. I drive slow 98% of the time. I pick my spots.

It is certainly possible to get the performace you are looking for but computer friendly and streetable are another question. The old Nascar Buick V6'* (274 c.i.) of the early '80'* were at around 550hp, carburated. Too bad none of that stuff will fit the newer engines.
