455 Bobcat dealer (install) on a 2006 GTO M6 Quicksilver
The mod is basically adding, Headers, exhaust (Loudmouth), Rockers and springs, 160 thermo, Underpulley, and custom tune. Normal kit also has the K&N air filter for the box, but I already had the Lingenfelter CAI.
Ordering time was 2 weeks from the dealer and 3-4 days for install. The 4 days was because they had to send the computer to SLP for the upload.
As stated in an earlier thread, the price was about $3.5K for the parts and another $1K for the install. The dealer states it is fully warranted by THEM (move to Chicago and the dealer there might balk).
PROs: Very clean install with excellent fit and finish to the mods. The Loudmouths are very loud, but consistent. The idle at 800rpm is lopey but solid. All accessories are fully functional (A/C, elect components, etc.). The temp runs about 10-20 degrees cooler in 80-85 degree weather, but not in stop-n-go conditions (in traffic, it still does not go above what the stock did, however). Acceleration is very strong. I haven't dyno'd it yet, but I believe the claim of 55 hp being added. It sounds stronger, but whether or not it actually is remains to be proven. The CAI really sucks in the air now... you can really hear it!
CONs: Well, it really is quite loud. I'm just getting back into musclecars (had 71 GTO 455HO in college) so it is a big change in sound. I wasn't ready for the pops on the downshift and it got my attention. This my daily driver and I have to see if the noise is acceptable. It does go really well with Metallica CDs though!
The good thing about the SLP package is that is modular (bolted) and it is very easy to switch out to the Loudmouth IIs for a quieter ride.
I haven't had a chance to really see the if the MPG goes up or down. I suspect in urban conditions it will be lower, but there may be gains on the highway. Also will have to check on the heater effect in winter.
Now for the files. I have a couple shots of the install. I have a *.WMV vid of the exhaust tone, but I have to figure out how to upload (sorry).
Thanks!
