Went [email protected]. Old best in Utah was 12.99@112. Nice to see going from 7k DA to ~1200ft DA had a nice difference in times. Not sure what to do next. Probably driveshaft and converter.

Congrats.

Converter first IMO.

 

[Unreal]

Yah, doesn't launch at all. Goes to show what DA does though.

 

[Mike Rousch]

Nice man!! Converter for sure!

 

[Unreal]

Mike, I'll be calling you when I need one. Also may need some tune revisions since I put the smaller tires on it it was shifting a bit quick compared to the street tires.

x3 on the converter.

Is the MPH low? Trapped as high as 113 in Utah so was expecting 116-117.

Air aid cai, SCT tune, off road x, 3.73s, 26" ET street (255/16). BMR lower control arms.

Weighed 3572 and 3800 with me in it.

Trap is spot on if you ask me. What were your 60's?

Glad to see you like Mike's tune, I'm digging mine too. Ran 12.6 @ 111.3 with just his tune/axle back/resonator deletes. That was on street tires and at full weight too. Doing an off road H pipe next. Hoping to be just about where you're at!

1.90, 1.92, 1.93 60's.

Humm, thought yours would be better. I pull that on street tires with less mods.

How is your tracks prep? What are you launching at?

My car, with just a CAI, JBA mufflers, and Bama tune, on the same 255 radials you have, ran 12.24 at 116 in 1000' DA. Added a Boss manifold, offroad X-pipe, and Mike Rousch tune, and ran 12.06 at 119 in 1100' DA. Yours sounds pretty good for 1200' DA.

I ended up buying my Circle D 5C from Mike Rousch, ran 11.58 at 118 in 1200' DA on the same tires. Went from a 1.93 60' to a 1.59 with the converter.

Damn, half a second with the converter?! How is it on the street?

Track was amazing. They were running NHRA prostock testing all week. Couldn't even walk on track without losing a shoe. Several mid 6 second cars were running the same day with no issues.

Launching 1200-1400, whatever the stall would hit. Tried just punching it, and tried foot braking it but stock stall doesn't do much.

I wonder if the 3.73 killed some MPH.

Trying to decide between 3c and 4c. Car is still wife's car and daily driver so can't go extreme.

It's good, no issues. Can definitely tell there's a converter in there, but on the highway at normal cruising the converter locks anyway and it feels like stock. Definitely worth it.

I wonder if the 3.73 killed some MPH.

Possibly. My car with the 3.15s and 26" tires goes through the traps at 7400-7500 in 3rd which is perfect. With your 3.73s you should be going through in 4th at around 6300rpm, which is not ideal. That might be killing it a little bit.

 

[Unreal]

Other issue was it was doing 1 wheel burn outs. Not sure what the deal there is.

Thinking a 4C since it is wife's daily and maybe the driveshaft. Depends on tax return. Maybe swap gears back to stock or something different. Just want a solid 11.5-11.6 car.

 

[wbt]

You can run mid-11's with a 3.15 gear no issue running the stock intake.

 

[Unreal]

Not even considering running anything but stock intake. I have the factory gears. I wonder if the diff is hurt. Maybe I'll get something like a tru-trak and have it thrown in with the stock gears. Gas mileage would get better. At what MPH would the stock gears need to shift to 4th? Seems like if I dial the car in to trap 115-117mph with a 4C converter I would be happy.

 

[BMR Tech]

Congrats! Keep up the great work.

See, with the stock converter you are best off leaving at idle. I've tried all the other techniques and idle seems to work best. There are a few guys who run at my track who are now in the 10's and they all said to stick with idle until you do a converter. The stock converter flashes best at idle.

What side? You sure it wasn't the limited slip doing that?
