Finally got 1/4 times for my LS1 swap.

Well here it is, me and my friend went to the gainesville drag strip tonight and just got back. Im a little disappionted in my times i only ran a 14.10 at 99.42mph with 2.28 60' times. Also ducky heres a picture of my time slip if i could get added to the 1/4 mile list.

Also will a GM Hotcam make those times better scince it has a 112LSA compared my stock ls6 cam 117.5LSA? Reason for asking im just wondering if i shoulde change to 3:73's from my 3:42's to hit 13's before my cam swap. Or if the cam swap will bring me into the 13's?? What do you guys think?

Thanks Brandon

were yous spinning the mph and ET are a tad off.

Im not trying to be a jerk, but this does not seem right for your setup.

the problem is not the cam. its the 60' time. i made it to 13.26 with the LS1 on a stock cam. get a torque converter and some slicks and watch the times drop almost a half second before the first 60' of track.

Your not being a jerk, I was disappointed too... i even got better reaction times but my 60' stayed almost excatly the same. I will have a TC next on my list anyone wanna suggest a good one for me in the 2800 - 3200?

Thanks

PI or Yank, Cant go wrong!

Less expensive options include a reworked stock converter or a trailblazer converter.

Reaction times don't come into play for ET or 60 ft times. You can sit on the line for 2 seconds and still cut 1.xx 60fts. You definitely need a stall, Yank is best bang for buck but PI may be best overall quality. Both are good. Like everyone else said, get your traction issues taken care of and you'll be in the mid 13's easy. I ran a 13.5 @ 99.6 with a 2.1 60 ft. I'm still kinda confused how you ran 1/2 a second slower with the same trap and only slightly slower 60ft? Not saying it didn't happen, just not sure how??:confused:

It might be the timing system?? We have it very good at HRP!!

Yea so i guess i will go out and get a TC, I cant see how i have traction issues with caltracs and stiffer shocks... my friend who has absolutly no suspension what so ever got a 14.2 at 95 with a 05 CCSB Silverado w/6.0L swap and 3:73's stock stall and cam. But he weighs 1000lbs more than me! Thats why i feel like i need gears or ether a lower LSA to get off the line better.

I had five runs over all, four of them were 14.1 at 99mph and one was 14.4 at 102mph(no traction) Looking at all my 60' times i had a 2.201 almost 1 sec lower than the 60' time i posted but i still! somehow got a 14.18 at 99.56mph...

Also just letting everyone know my truck is a pig!! from 0-25mph, but its great from 30-120mph it just keeps pulling really hard up high. once i hit the 120 mark i let off but i was still pulling hard.

got you updated on the list! and yeah that really doesnt make sense, your time and all

0.2 in the 60' won't find the 0.6 you're missing in the 1/4 mile. Where are you shifting this thing?

You definitely need at least 3.73's or even 4.10's. That with a stall will get you there in a hurry! 3.42's suck off the line...ask me how I know!!

Hey,

Allen has me shifting at 6300 for my 1-2 then 6200 for 2-3. I only have a CS on the tranny, thats it. Im suprised i havent destroyed it....

Well i didnt really want to get a Torque Converter until i could afford a FLT and a Torque Converter because i didnt want to have go in there twice. Would gears do good for me compared to the Torque Converter? Plus gears are only about $140 brand new ring and pinon i would keep my stock G80 for money reasons.

3.42s aren't bad off the line when you have monster torque. :rock:

Yea which i guess i dont have....

That's what I thought (RPM) but I failed to look at the head mods in your signature. I assume you're still in 3rd at the lights with that much RPM?

Yea i shift into 3rd at 94mph then at 99mph i cross the 1/4 mile. Would lowering my shift points improve my time? I have HP tuners and what little tuning knowlege i have...

Also the 05 CCSB Silverado that ran 14.2 at 95mph with the stock 6.0l swap had 5700 1-2 and 5800 2-3 shift points.

That's a question for someone else here. if Allen put it there, it's probably the way it shoould be. Wish you had a video.

Ill get my roommate to take some next time we head down to the track.

What rpm are you guys power braking to with stock torque converters? just to see if im doing something wrong. I launch from 1500rpms highest i think i can get it. Maybe can get it to 1600...

I launch at 1500 RPM's with a 3k stall. Then again I have been spinning off the line lately so maybe I am doing something wrong! lol

Mine is pretty slow compared to a lot of the guys here but mine is much quicker leaving from idle. I have a lot of weight and a stock converter.

i told you before, you need to bring that truck up to my tuner in Jacksonville so he can do his magic on it.
your truck should be way faster than that.

who does this magic and is it a live dyno tune? how much does he charge? jacksonville isnt that far away.

sent you a PM

Whats the stall on a trailblazer ss converter? And how affordable are they?

Buy a TCS performance converter it will be the last converter you will ever buy

expect a 1.8x 60' time with a tb stall. not bad but not great. awesome for drivability though

You dont want the TBSS convertor...you want the one out of a V6

Really. Why not the TBSS converter, and why is the 4.3 V-6 converter a better choice? I know nothing about converters. Thanks

The TBSS converter stalls lower (i think 2200, correct me if i'm wrong) than the converter in the 4.2l I6 (not a v6) which is around 2600 rpm
