    Thanks for the reply. I just bought a maverick and was wondering what to expect. I’ll unfortunately be adding a bit of ballast myself once I’m in it.

    Drag from the alternator charging will only slow you down.

    Nice. Have you driven it with that gear? How does it cruise RPM-wise?

    Yes..... About 2800 for 70mph, so not bad at all.....

    Hey Franktf, I just drove through Bradenton out 64 the other day and they had e85 back. I don't remember if it is at Thortons or the Race Track...but they are both pretty close to the interstate. Thortons was the go-to for it in town before the Race Track started carrying it.

    I messed with the a little this weekend..... I drove it around some today, made a couple test blasts..... It seems to be running pretty good, makes about 17.6lbs the way it is now..... Check the logs out and everything looks good..... I did pull the radiator before I leaft the shop, so I can add a pressure transducer to the cooling system as suggested to me..... I just seems like a good idea to know it the cooling system is seeing any excess pressure.....

    All right, I got everything all back together and working including the new coolant pressure sensor..... As it turn out there was some kind of a tune-n-test today at Showtime Speedway, so I said why the F#!% not..... I went out, cooled the car and made the first hit..... Car felt a little flat, kina of like when it blew the head gasket..... All was good with the motor, but it looks like my new custom built converter sucks the big one..... I cooled it off and made another hit, same shit and the trans got way hotter then it has in the past..... When I got to the et shack after the second pass, the guy there said something smelled hot(the motor was only 170)….. When I got back to the pits I stuck my hand under the car and the converter was extremely hot..... I am still foot braking the car, when I staged it for the second pass I loaded to 3200 and bumped in and while I was waiting on the tree it flared all the way up just over 4000 on it's own..... The converter flashed to 5200, the other odd thing it does is it has a kind of gradual rpm gain to about 5650 the ramps at least twice as fast to 6300 where I shift(it doesn't seem loaded the same,it also loses a couple #'s of boost during the upper rpm)….. After the shift it drops back down to about 5400 and has the same slow ramp as in low up to 5600(that's as far as I care to go, it's only an 1/8 mile track.....With the other converter it had a very linear smooth rpm ramp, I was just overpowering that converter(it on had about a 3-400 rpm drop at the shift)…..

    I am going to check the trans and make sure it didn't get hurt(I don't think so), and put the other converter back in and see how it acts.....

    The pass it blew the head gasket was the first with the new converter, I figured it didn't feel great due to the blown gasket..... Apparently that wasn't the only reason..... Now due to the head gasket it has gone through a few other changes(heads, gaskets and lifters)….. So putting a know converter in it will tell me if there are any other issues..... At least I think it will.....
