holy shiznitts, how can you stand it, you have to be getting so pumped up about now. I'm so glad for you.
Awesome update!
Kaboooom!
IT'S TUNE TIME.
Over twelve months ago my 06 VK45 went in to have JWT S2 cams installed. Due to a variety of issues beyond my control the engine failed three times.....
Before the current work I had done:
• INJEN CAI (Actually JWT POP
• NISMO S-Tuned exhaust (actually Invidia Gemini at this time of first tune)
• Electric fan conversion
• Transgo shift kit – Did not add power, did not affect numbers
• UPREV Dyno tune on 4.01.10 Increased WHP to 250 and Torque to 317 Ft. Lbs.
What has just been re-installed and is up for the tune tomorrow:
• JWT Cams/Springs
• Reworked OE manifold - Ported, and polished
• Ported heads
• Bored OE throttle body
• Custom made 304 SS 4-2-1 headers
• 300 cell HFC's
There have been guesses as to what the new WHP and torque will be. There won't be huge FI style gains and the power definitely will be under 315 WHP, possibly under 300. Care to take a guess at what the WHP and TQ will be? Don't forget to factor in AWD drivetrain loss.
BTW If it blows up this time you might never hear from me again :sluggish:
