LS Swapped BMW Fast List? (1/4 Mile Times)

[Bsaint]

I know a lot of Forums do these lists to keep track of what people are running and figured we could do the same.

Simply attach a video and timeslip and we will keep track of the car/setup and 1/4 time.
(Must have video for it to count)

I'll start it off with one from this past summer.

Not my best, but it's hard finding good video help and I can't video and drive haha.



Going to throw a tire back on this season and get some video of the 11's for it to count.

Gonna be interesting, haven’t really seen or heard people talking about 1/4 or 0-60 times on their Ls swaps.

Agree'd I know not everyone drag races, would be a good idea to motivate others to get out there and get some info.

[Tim Mc]

I think a great idea...unfortunately we don't have a decent video:





Our excuses are no tach, hard/aged Firestone tires, and only 38 psi on the fuel which limited topend power - likely would go 12.8's with just the fuel correction.

Car is 3200 pounds (no fuel/people), stock 5.3 aluminum L33 with mild Crane camshaft, T56 Magnum, and 3.92 gears.

Stock 220,000 mile automatic (3240 pounds), it ran a 15.40 @ 92 MPH.

Good video help is deff hard to fine I hear you.

Huge improvement over stock I don't think you should have a problem getting into the 12's with a good tire. How much power did yours make only thing that seems low to me is the mph. Nvm found in your thread 339 whp & 337 tq


Added up to the list!

[Tim Mc]

I like the idea as often wondered what the return on investment with all the funds and time to do the conversion. These projects have seemingly low percentage of actual data...actually finishing them also reduces the information. Agree on the mph for our car...a partial culprit was the internal fuel leak inside the tank - tightening the hose clamp in the correct place brought the psi to 78! It seems like a good example of stock LS installation.

Paging RulyLSX....

Mine isn't to crazy.

Best I have done is 12.6 @117 or 118 i can't remember. that was with a 2.0 60ft.



That was NA around 400 HP


I am now boosted and 505 HP, waiting on new drive shaft then i'll be hitting the drag strip again.... I want to be in the 10's some day with the car, hopefully this year

Hell yeah looking forward for you to turn that thing up and let it rip!

[lloydjoe]

I don't have a video of my best run but was 11.81@120.35 mph. LS3 w/ported heads/cam, t56 magnum, ford 8.8 w/4.10's and Mickey Thompson tires. Best with the street tires was 12.59@108.25 mph, too much of the skinny pedal and not enough traction.

went out to the drag strip first time since being boosted, had road racing tires on it(toyo r888r) and the 60 foot sucked, low boost but it's my best time so far.

ET 12.2
MPH 123
60' 2.2 lol

Going back out in a couple of weeks with slicks/skinnies

Gotto have video to be added, I did a 11.7 at 118 as well no video and I'm not including that either.

Good mph for low boost! Can't wait to see that thing back out there turned up on that drag pack! cut some 1.6 60's and you got it!

You should hyperlink the times to the youtube video in the original post.

Some pretty good times there. How are your guys diffs and CV axles holding up.

Bsaint: ......12.58 at 117 mph (5.7 - cam only, street tire) 422whp - 389tq 2,800 lbs (E36 M3)

How are you managing 422 at the wheels on a cam only 5.7? With 15% driveline loss that's 485 hp at the crank. I just got my build fired up in April and was estimating I'd only make about 425 at the wheels, although it's not dyno ready yet.

[Bluebimma]

My fastest, recorded, is 13.09/13.1 at 109mpg with my improperly tuned ls6 that made sub 300.

My fastest was 11.7 at 118 with my current 6.0 that I tuned myself but no video

Just out of curiosity, any chance of running a hood with the LSA? Maybe make a shaker setup?

Your asking how I dyno'd 422 when you estimated your build and haven't dyno'd it yet? ... just making sure I'm understanding that. You can't just add %15 to a "wheel hp rating" to get crank that's not how it works. There are too many factors to consider such as what wheel/tire on the car, what gearing, what correction factor, elevation, not to mention the cam specs, and what heads etc.

Also in a manual car there is a lot less drivetrain loss, more like 11-12% It's more like estimated 460 crank. (And considering LS6's are crank rated at 405 that's completely feasible/realistic)

How are you estimating your build at 425 what's the info on it?

you have video of the pass? I just see a link to timeslip.

Some pretty good times there. How are your guys diffs and CV axles holding up.

My original struggle was breaking front diff bolts, I wen't through 2 or 3 and then switched to the Active Autowerkes diff Brace.

After that I blew my stock 3.23 diff on a hard launch with a tire. So I swapped to 3.91 and cryo input shafts on the axles other than that it's been great.

I really don't drag race it a lot otherwise I would upgrade to a large case diff, I do want to get back out there on a 15" bias ply to minimize breakage.

Hopefully this fall.

Updated the list.

Nope. I typically go to the track alone on random whims. Dont worry about the list, Ill take solace that its still faster then the rest.
