Man o man o man!!!!
I am dead serious, that is the most perfect first test drive I have ever taken, period, in any car, ever!!!!!
- I let her idle up to operating temperature and had to add some fuel to my old map
- I then had a fair amount of hesitation on very slight throttle so I upped the TPS enrichment
- Played with fuel until the fuel trims leveled out close to zero at idle
- Shut her off
- Double checked everything by look, feel, touch
- Started her up and went for a 5 - 10 minute drive when all I set out to do was go to the first stop sign and back
I'm not kidding, aside from a very slight hesitation with a feather foot on the throttle, it was brilliant! I ended up getting her up to 72.8% throttle (low rpm), 13.4% engine load and about 45 mph.
I was also very impressed with the BOV noise as it was non existent at idle or cruise. You hear it a little rolling to a stop or on throttle release but nothing like the jet sound of the old C30 on a 1.8l. Some might even like it this way as it wasn't annoying at all. However, I will still end up quieting it down.
Now get this!!!!!! I'm sure this will change over a much longer run but the IAT's were very impressive. With the stock intake I was seeing an early 25 degrees delta between the TB and ambient temps. This quickly went to 35 on the highway and ultimately 50 degrees on a hot day.
In this 10 minute drive, it was 95 degrees outside and the IATs never went above 108 at a stop sign!!!!!!!!!! Then when I hit the gas, it would go down to 104 then level off at about 106 while at a 35 mph cruise!
Also, coolant temps never went above 198 and seemed to hover closer to 196 or so.
That is absolutely freaking awesome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
