Default 1st drive

Well took it out for the 1st drive today after having a friend and SamNavy look over the tune idling in the driveway and they both gave me the thumbs up. Well my 1st drive was 12 miles to a friends house to weld up the new exhaust.

Started and ran fine, idles like stock and AF were looking good. I had to take it on the freeway to get there and it was running lean @ 55 so I was adjusting the VE tables as I was driving (thats fun). Was 16-17AF at cruise, not good. After adding fuel in a few cells I tried to just keep the motor in them for the rest of the drive. Seemed to work. Stayed out of boost for now.

Arrived and noticed there was steam coming from the middle of my NEW god speed radiator...great. Must be a pin hole because I can't see coolant just a little steam and I can smell it. Never got hot on the drive tho, I was watching the dash gauge because I still have not played with the easytherm values and it was pegged @ 215* the whole drive. Can these be welded up? I h8 to have to deal with shipping. Guess you get what you pay for.

Overall it went well, I get the car back this weekend and than I can work out some of the bugs.

You gets rads soldered, not welded. I don't know if it's better to have done or get a replacement, maybe someone else would.

Lean cruise is not such a bad thing, the right amount of lean will get you better mileage too.

Aluminum, I just figured they would Tig it??

But how lean it too lean? There got to be a "bad lean"

I think 16:1 is good for your gas mileage, not good for your emissions, and may make your egt rise a bit more than 14.7:1 would.

Under light load cruise conditions, you can run as lean as you want until it starts missing/stumbling. 16-17 is probably right at the limit of lean without driveability issues.


...And Johndoe beat me to it.

If the godspeed have the rows epoxied to the tanks and that's where the leak is coming from, I'd send it back. Otherwise get it patched. A/C shop might be a good option for the repair.

I lean my car out till it pops/skips/stutters. Then I add a bit more fuel till I'm happy. As long as throttle response is good, why not?

Actually, I think you get better mileage from a 16-17 afr, but I drive around at "18-19" all the time.
