Last night i retuned my car with the addition of Skunk2 Tuner 1 Cams. Here is the setup:
84.5MM Sleeved B20 Block
GSR Head w/ Skunk2 Tuner 1
Supertech springs/retainers and flatop valves
Wiseco 10.6:1 pistons & Manley Turbo tuff rods
Track Forged T4 Top Mount Manifold
3" e-cutout Up pipe (with 2-1/4" piping to stock muffler when e-cutout is closed - sleeper)
PTE6262 T4 82 A/R
Southbay 1200cc injectors
Full Blown Dual Fuel pump with (2) Aeromotive 340lph, -10 feed and -6 return, Aeromotive regulator.
Tial 44mm Wastegate and Tial 50mm BOV
68mm throttle body
Edlebrock Victor X manifold
Tuned by me on Hondata S300 on a dynojet on 93 Pump gas

Below is the before and after dyno from switching to Skunk2 Tuner 1 cams from the GSR cams. Both tunes were on the same wastegate boost of 15psi creeping to 17-18psi . Decent gains in the mid range. The GSR tune only shows 458whp but when revving it out to 8.8K it was in the mid 460's. I didnt use that dyno graph to compare because the dyno ignition pickup was cutting out.



The setup below (dont bash the up-pipe, its painted and looks a bit better)

 

Very good gains!

 

Nice work man! I love seeing stuff like this.

Did you change the timing at all after the cam swap? How much total timing are you running at this boost level? Great numbers for 93 pump! Keep up the good work.

 

Anytime I tune when I add parts to my setup I always lower the timing by 4-5 degrees n then bring it back up. I started at 12* at 17psi and ended up running about 17* total timing. Before with the GSR cams it was right about the same timing as the skunk2 tuner 1s.

 

Sounds like a smart way to do it. Thanks for the info I appreciate it as I'm just starting to learn how to tune my own setup.

When i saw the fuel system setup listed for this car i was expecting it to be tuned on e85 lol.

 

Injectors will limit me at 550whp. C16 should be good for 650whp
