Default trip to the track/ 10 bolt carnage

went to the track after putting a ss3600 in and getting tuned at bigshot/pcmforless by brian, car put down 340hp/384tq

1st pass resulted in moving about 2 feet and a few hours of fun







after getting the 3.42 rear in(was 3.73) the 2nd and only pass i went 12.7@105 1.74 60ft.. i have a lot of testing to do to get the car down the track perfect. I left off 2step at 2400rpm, it felt nice but i think it has a little better 60ft in it, the trap seems a bit low to me (was trapping 105 untuned and without the ss3600) any opinions why?? i will have an update at the end of the week when i make it back to the track and hopefully it will be cooler

Are you saying you broke one rear, and had another complete rear with you at the track that you swapped in, at the track? Wow, that's what I call coming to the track prepared, lol.

anytime you drop your et you will loose mph, unless you have done something to add power.

And I thought I went to the track prepared, I just bring a small toolbox with some spare plugs, pushrods and things. I never broke a rear at the track but if I did I'd call it a day. I'm impressed, that's real dedication to racing.

Not necessarily... you might not have "added" horsepower, however the average horsepower over the run might increase. After all average HP is what makes cars go down the track, not torque or hp peak.

Nice. Looks like my 12-bolt/Strange diff/33 splines did after a few too many 4k rpm + clutch dumps on sticky tires.

Mike you should consider offering destructive testing services for all drivetrain type components, you have no problem finding their limits

You may have other problems keeping you from gaining more, how healthy is that 4L60?

Time for a 9inch and lots of juice to catch Dirk...

Which 224/230 is that, XFI? I'm having trouble remembering which one Steve put in there.

http://shop.brutespeed.com/Moser-M9-...y-Complete.htm

The Moser M9, which is their fabricated rear, is a good way to go. It doesn't add any weight to the car and with either a spool or a Wavetrac you won't break it. The M9 comes with an awesome chromoly torque arm and transmission crossmember, and this combo really made my Z28 hook. These rears are shipped out just two days after the order is received. Bob

Back in the day when we were street racing a lot I would always look under the cars, if it had a ten bolt I'd double the wager

Al 95 Z28 and 2002 Z28 now, 67 SS, 375 HP 396 then.

What valvesprings are you running? That's one valvetrain KILLER of a cam, those lobes don't belong anywhere near a street car. How high are you spinning it and how long has it been together?
