so 16.5* timing? you got alot of room to bump that up. unless you're heatsoaked all to hell... I run 20* all day with no cooling mods on 2.8" cars as long as their fueling is good and the iat doesnt go through the roof.
After the meth, you should be able to throw 25* at it running a 75/25 or 80/20 methanol mix.
Still, good #s for that low of timing.

Mine made about the same power with about the same mods. Stock cat-back, ZZP catted DP, Air Box Mod, and a 2.8... made 241/220. The only cooling mod I had was a stage 1 HE. Now I have a header and working on getting a cat-back, so I'm curious what she'll gain.
