Engine and Tune

GZ3

my basic car care package is filters, Id recommend changing over to a dry filter media on your CAI, clean MAFS with CRC electrical contact cleaner vs the designated crc MAF cleaaner. We realized it left a residue on the contacts once it dried. The electrical contact cleaner does not. Inspect throttle bodies and clean as needed. Make sure you disconnect the battery when servicing these or idle while issues could come about. Whatever oil your running, get a UOA, see if your good there. I always do a fuel injection cleaner every 7-10k depending on habits. The best ones Ive used is BG, amsoil, and good ol lucas "deep clean injector"...redline is also pretty good, has allot of PEA the detergent agent in chevron techron. Spark plugs is next, I recommend a plug with a silver core and electrode for best thermal conductivity and electrical. Brisk racing makes the absolute best plug on the market, hands down. Other than a compression test/leak down, Id get a tune....some guys replace their up stream 02's after a couple years of hard track time. The VHR is such an amazing motor one you get the oil cooling under control

Just an update:

So I bought this car with 22K, and it is now approaching 60K miles. It has been tracked no less than 2 days a month since. I would say 80% of the miles I have put on it are either driving to the track or at the track. I travel for work a lot so even though the car is a DD it is rarely driven over 15 miles when I am at home.

Had the plugs changed, mafs and TB's cleaned and did the compression and leak down per recommendations, here's the results from Corner 3 Garage:

Compression: Cyl1 196 PSI, Cyl2 210 PSI,Cyl3 210 PSI, Cyl 4 215 PSI, Cyl5 215 PSI, Cyl6 214 PSI.

Leak Down: Cyl1 92 (8%), Cyl2 93 (7%),Cyl3 96 (4%), Cyl 4 95 (5%), Cyl5 96(4%), Cyl6 95 (5%).


Car is currently being E-tuned by Specialty Z, so will run it on the dyno after that is done! Will be happy with anything over 305, I only have CAI's and HFC's so I think that's a fair target.
