So let’s start with the drivetrain. The car came to me with LG Pro 1 3/4″ headers with catted x-pipe; Callaway Honker air intake; GHL Bullet cat-back exhaust. (as an aside, I thought the catback was going to be too loud and droney, but is actually a good sound with no drone)
It was tuned back in 2007 and put down SAE 388whp.
My power goal is to run consistent 10.9x 1/4 mile times with a density altitude (DA) of 3,000′. I’m wide open at this point as to how I get there; from a H/C/I LS1 to a Gen IV RHS block running 454ci. I’ve got plenty of time to figure that out as I won’t be doing this for quite some time.
I’ll also need to get supporting mods done first: built 4L60E; built rear with 3.42 gears (maybe 3.15 depending on engine size); driveshaft, couplings, halfshafts.
In the interim, I’ll have my tuner look over the tune since it’s been a decade+ and see if there are any opportunities with the current configuration. I’m also exploring converting to flex fuel. This model year PCM has the flex fuel settings, so it’s just a matter of plugging in the sensor and enabling the PCM. Provided I don’t need to upgrade fuel pump and injectors I will be doing this forthwith.
So to kick it off, I’m installing an AEM 30-0310 X-Series Inline Wideband UEGO AFR Sensor Controller, logging some “driving” and having my tuner analyze the results.
Stay “tuned”. 😉
