Do you know what DA you had for the track? I think the mph seems low for bolt on and cam..my 02 hit 111 mph bolt on only and 4000 stall.. maybe it's DA, or tune?

Does the car feel like it's running strong? Smooth idle?

Ok Thank You Denom, Not Sure on the DA RollinSScamaro Great ET & MPH Out of You're TA. madmike9396 I'm Thinking It's Slippage from the Vigilante.

Definitely under achieving there unless you're at some serious DA. That K&N Fipk is junk I'd go back to a lid setup and SSRA or Chrs1313 air duct system. Take the front sway bar off if it's still on there

How much does a ported dorman ls6 intake cost

HioSSilver

He's in ohio so tracks shouldn't be terrible. But that way off. Car shoukd be running that or faster with bolt ons.

These cars are very much capable of running 11s these days with bolt ons. You'll learn alot about them doin it that way to.

Tq is way down to.

jhshnh

I agree with Hio, torque is down. He should be in the 11s pulling high 1.5x 60ft times with that power.

Is the car spinning at all?

mph seems way off. It should not be under 114-115mph...in bad condition. My old LS1 with a small TR 22x cam was running 12.4-12.6@116mph full weight, track noob driver mod LOL, stock gearing, horrible 2.1-2.2 0-60ft. It had LS6 intake/ported TB/ported 98' heads (stage 3, I think they were knida pretty good), stock rear 3:42 with street tires. This with a big knock retard on launching cause the Ypipe was banging the floor real hard. man I had no clue at the time...

Cam choice?

The K&N FIPK Out Performs the SLP Lid I Had Before. Sway Bar is Removed My Car Only Weighs 3300 with Me In It. I Think My Issue is Converter Slip.

Looks pretty bad to me no offense. I'd expect trap to be 7mph higher in decent da. Those are bolt on times

iTrader: (5)

who did the tune? like others said, the mph seems off. I ran a bit slower than your ET with stock CR in my LQ4 but with a crappy 60' haha.

Heads are def holding you back some, however IMO still should of cracked into the 11's
