Any Ideas? Guys, Ive got a 97 LT1 M6 Z28.
Mods are:
3:73s
Centerforce Clutch
TransDapt Cold Air
Hypertech Air Foil
Dynomax Bullets
PaceSetter Mids
CSR Electric Waterpump
Nitto 555R's
MSD Coil
BMR STB
Mad Z28 Tuned
Comp 230/236 576/571 113'LSA
1:6 Comp Rockers
The care feels really good on the street but when its track time:
13.7 @ 104 Horrible.
I have beat good cars on the street but for some reason track times just suck.
The car doesnt seem to get off the line. It almost seems like it takes to about 3000 RPM to really get moving. Even feathering the clutch to get off the line without alot of wheelspin 60 ft times are still 2.2 or around. Driving isnt an issue. Im no Maverick but like any other M6 driver i can get around and hold my own. Cam too big? What do you guys think can really help this LT1 out? Thanks guys

The 113 LSA and lift makes me want to ask if this is an XFI grind?
What springs are you running and are the installed at the right height, the XFI grinds require a lot of spring and beehives are best since the XFI lobes are designed to take advantage of the beehive strengths?
That said the XFI stuff while touted as the very best really is not performing in the real world.
On stock heads I would say it is too big as well and that with the T56 4.10s would have been a better choice, even for a daily driver.
You do have the MPH to run low 13s.

Yea its a XFI cam. I also went with Comp Rockerarms,pushrods,lifters,retainers, and springs which are beehive. Yea i agree on 4:10s its would help it off the line.

Get a hold of some sticky tires. and you say it is slow under 3000rpm, on the track you do not want to be there anyway. your 60 ft time shows you may want to try a few different ways of launching and see what drops that time the most.
