Circle D Converter First Impression
#12
Installed my fresh rebuilt tranny last Friday with circle d 3200, hd2, servos etc.. Checked the fluid and put a new tune on the truck. Several wot runs, 4 hi launches adjusting shift points, timing, and fuel.. Took it to the drag strip the same night for test and tune and cut 2.12, 2.18, 2.16 60 ft times in my heavy crew cab! Hasn't missed a beat! Another very very satisfied customer here also!

A buddy of mine did the tuning. He uses hp tuners. 10 years experience in tuning. I haven't bought a camshaft yet. I had stock48 spec that cam for a tvs1900. But I recently purchased a set of tsp 2.5 heads with 1518 springs (10,xxxmiles) for $400. My buddy put his truck back to stock. I'm thinking of having them milled .030 and going with a tsp 220 on a 112. Still undecided for now!

Your comment about wishing you had more stall is probably the most common one. I may get to beat mine this weekend if the rain quits. Compared to stock is an appreciable difference. Too bad nobody makes a trans brake for a 60E, lol! Might help sensationalize the holeshot a little

Break in is only for the lock up clutches.
Chris nailed the converter in my former Camaro. Told him I wanted the best of both worlds (n/a & bottle). Circle D 4C 3800 flashed 3750 n/a and 4200 on the bottle. 60' improved .12 n/a and .10 on the bottle and gained 2-3 mph on the big end vs Vigilante 2800. I was still dialing in the suspension shooting for a 1.3x when the track closed. My best 60' was a 1.42 with 3600# raceweight on a stock 10 bolt. I'm sure it helped that I knew the weight and power that I was making n/a and on the bottle.
I will be a return customer with my next project.

Well matted the gas pedal tonight. Wow. And I'm running the stock tune corrected for speedo compensation only. Tanked up with high test 93 tune goes back in tomorrow. Between the new FP regulator and the converter alone it's a runner. Can't wait to data log, adjust the LTFT's and PE and reload it. Can't imagine how much better a truck like this can be with a custom tune, larger valve heads, some more compression, TP 220 and headers. Unfortunately for my bank account I'll probably get to find out.
