Yep and they say for every 100 lbs, that's 10hp, .10s and 1.5mph in the 1/4
Sooo doing the calculations...
My 440rwhp LS1 N/A car with ~600+ lbs added comes out to:
-60hp = 380rwhp
-.6 sec = 12.6
-9mph = 116mph

...just going off that one pass

I'll give u the fact that the majority of cammed cars don't run to their potential. that doesn't mean they aren't capable. I would've been disappointed to spend $3k on heads/intake only to gain 4 mph. what would these cars have done at sea level or negative da? nothing outstanding, but respectable.

I have no Idea, I put the car on the scale at one of our recycle places, and thats what it came in at, with me in it, was around 3875ish if i best remember. You cant compare a z28 with a my ride tho, got to remember the wing, hood, all powered and leather interior etc, add weight to it.
Im thinking of removing bumper supports and passenger seats when i return to the track. Got in touch with frost and will be working something out. Might just go 100 dry for now, and see where that lands me... If i break 10s in the 1/4 There will be no need to add 150. Its my goal and leaving it at that.

Did you see the link Mliel attached? Plenty other similar results where that came from.

I'll stick to "real world" results and when you can show me what a setup like that is supposed to do in your car then we'll talk.


btw, go Niners!

No offense op, but who puts tiny single pattern cams in a car that flows twice as much intake air as exhaust air anyways?

I bought a bigger cam. we will see. I'll be disappointed if the car doesn't go 117. it went 109 with a lid and weld in fm 80. I pulled some weight and added a cpl things since then. haven't been to the track, but it seems to run all right

NOt sure. Most still DD cars seem to be able to drop to 35XX with driver. Brett and me both are 190-210lbs. Our manuals was a little lighter. But ya the lightest is race cars that have weighed in at 2600-2700lbs with drivers.

I suspect to be right in the 3400lb raceweight area.
