Before the 4C converter I went 12.93@106.5 with a 1.91 60' launching at 1500. After the 4C converter I went 12.67@104.6 with a wheel-pulling 1.67 60'. It pulls the left front for sure, maybe the right as well. Im more than impressed with this converter, as well as Chris's advice, suggestions and excellent customer service. Im cutting better short times some cammed LS1's in St. Louis. All this from a bolton LT1. Ill post time slips tommorow.

Yeah stock converter was 12.9's. I just switched a month ago, tonight I ran the 12.67. Thanks.

out of curiosity what were your 1/8 times on those two runs?

Deerhunter-Z28

Not bad, I doubt you're pulling the wheel, probably just feels like it. And if you're pulling better 60's than cammed ls1's their cars aren't set up right or they can't drive...lol. Post up the slip when you can.

My last time to the track with my 4C I was pulling better 60's than two cammed LS1's with even more gear (4.10's). So it is possible!

Deerhunter-Z28

I agree it's possible. I went 1.52 w/ a pt4400 in a bolt on 99Z. I'm just saying a properly setup cam car should out-60ft a bolt on lt1.

8.09 on the first, and 7.99 on the second.

Both the LS1 cars are auto's it kinda hard to screw that up. My car is just setup well. The LS1 cars are full bolton with mid 230 cams.

Your stall is almost a 1000rpm bigger than mine, not to mention im stock intake, TB still. Once im full boltons I should see 1.6 flat.

congrats! but I would have thought you would have dropped more ET then just 2.6 tenths??? are you spinning at all? when I added my stall I dropped from a 8.6 1/8 to a 7.9 untuned!!!

Deerhunter-Z28

Yes, you're car is setup well and the ls1 cars aren't, pretty simple...lol

i thought the same thing.. but still not bad at all..

lt1s dont need a 4k stall.. they do good on a smaller-ish stall..



it is possible to raise the tires with a 1.6 if you have good suspension and weight transfer..

no reason to be a jerk guys.. honestly he really is pulling better times than a LOT of cam only and some H/C cars..

i see a lot of cammed cars not pulling quite the same 60ft as stock ones. i am wondering if it is because a lot of the cammed cars don't kick in until 5000 + rpms. i only pulled a 1.69 in my cammed ls1 and a yank pt 3800. however, i bought this stall not for really hard launches. i wanted some efficiency top end too. i am full weight and i only run 3.23 gears. the str on the stall is only 2.0 so it isn't a hard hitting one. however, this stall plus a swap in brands of long tube headers picked me up over 8 tenths in the quarter....

most just get too small of a converter and are scared of going to a deep gear..

get a 4k converter in an ls1 with some 410s.. it likes the 60ft.. mine loved it.. i jumped other H/C cars HARD out of the whole.. and had plenty of top end to pull it through, and usually trapped much higher also..

You picked up .24 in the 60' and .26 in the 1/4 but only .1 in the 1/8?

It's a gain, but not one I'd be happy with. Unlikely that he's pulling wheels either.

On a side note, Lemons, why did you sell your car? Couldn't get out of the 7s/11s?

lemons12

iTrader: (71)

i was pulling the tires with high 1.5s..

didnt try.. right after i ran all the 7.2s i decided to sell it.. i had a couple buddies offer me their 28s and wanted me to go back down to see how deep i could get in the 6s.. but i lost interest.. i want something faster, but more streetable..
looking to hit mid 6s but drive like a near stock car on my next build..

I'm pulling a tire with a 1.5, but it's a little stronger than a 12.6 @ 104 car.

Turbo is the way to go for what you want.

lemons12

iTrader: (71)

same here.. but what it does on the top end has nothing to do with pulling the tires.. lt1s arent known for the top end at all.. 12.6@104... 12.6 in an ls1 is around 108+..

i thought about that... got turned off of that real quick..

then thought about a procharger..

im going to try nitrous first, because its the cheapest and i dont have to use it unless i want to..
after that im going to try procharger..
im sure the nitrous will get me there.. if not i have two back up..

My bad, I was going 8.3 on the stock stall, went 7.99 on the new one. The car is twisting off the line. Ill get pics once they are posted, not sure who took at my track took them. You have to remember that Im a bolton car, and not a full one at that. Ive got headers, a stall and 3.73's. I dont see any other LT1's cutting 1.6 60' with those mods. Im shooting for the bolton record, and Im slowly working towards 11's at the moment. Im spreading the word that Circle D makes excellent converters. Im on stock suspension btw.
