First time out I went 12.6@111 MPH with a 1.88 60' which was a .3 reduction but the track sucked. Well tonight it was hooking and I went 12.1@112 MPH with a 1.59 60' on DR's. I think on a perfect launch I could have cut a 1.50 and got my 11 but the track went away. This is a bolt-on car 3800 lb. race weight. I am extremely happy and wanted to say thanks

Hell Yeah!! I have the 5C and my best 60 so far is 1.43. I got some more tweaking to do and im hoping to see some 1.3XX. Are you flashing the stall or foot braking it when you launch? I can see you getting low 1.5Xs no problem and hopefully that 1.4X will follow.

Good work!

Circle D doesnt F--- around. My +4C punishes the 1/8th for what little engine mods I have.

are you cam only with stock heads...also do you have the lockup clutches in the converter...nice times what is your raceweight

Intercooler2

iTrader: (24)

I tried both ways and think 2500 and flashing worked best

Minshall

Yup still on stock heads and yes the converter has lockup. As for raceweight im not totally for sure. Last time i weighed it it was 3350 with me in it. Since then ive taken some more out of it. My goal is to get it down to 3000 with me in it.

How do you like that 12 bolt. Would you go to a 9 inch if you had to do it over?

Minshall

I love it. Its lighter and it bolted right in with no problems. Mines narrowed 3 inches on each side and has the strange brakes. I know the 9 inch rearends are strong too, but most of my friends have 12 bolts and havent had any problems with them. Either way, you cant go wrong with a 12 bolt or 9 inch.

hows the drive ability with the 4c?? any noticeable drop in mpg?

najaf4life

nice numbers... I still have my "3C" and yet to install....

You will drop some MPG if you are City or stop and go driving but on the highway it hasn't really changed. It isn't my daily so I am okay

3600-3800 is about what you can see

Minshall

Thank you. Now that I have a cage i can finally go and start dialing the car in. Im hoping for some 10.5Xs out of it.

The 4C actually brake stalls to about 2400-2600 depending on your engine/weight set up. It should flash to 3600-3800 rpm, again depending what your engine HP/TQ and vehicle weight is and what the builder spec'd the TC out for.

It is a good comfortable daily driver converter and obviously performs very well at the track. I almost stepped up to the 5C in our mid 11 second SS, but I know the 5C hits real hard and we are still on a 120,000 mile 10 bolt rearend.lol. I'm not ready for that one just yet.

Excellent report and results man!

I agree TXCAMSS, the 4C is a great choice for the weekend warrior. Excellent track times and street manors.
