realistic LLY stock turbo 1/4's
 
so before the start of the season this year i should have built trans. just curious what everyone thinks is a realistic time for me to shoot for at the track. 6900-7000lbs as it sits, 265's, caltracs, tracks at sea level. hoping to pull at least 1.6 60' times. may be able to shed a little more weight

i know ricks lly went 12.2 on #2 only but i bet hes lighter then me by a good amount.

12.5-12.6 reasonable? i would be really happy if i could pull off a 12.5

its a cc/sb

I know it may seem easy, but you'll be doing good to get anything in the 12s.

12.5 is a reasonable goal. Who's tuning?

high 12's should be a good goal IMHO

Redbowties88 02-01-2010 03:26 PM

high 12's wold be nice. mid twelves would be better:thumb:

by the pictures in your avatar your truck is lifted? chances are you will lose .1-.3 right off the bat... Elevation plays a HUGE role in how your truck performs. 12.5 at 6900 hp is not a realistic number. 12.8 is... Ricks truck also cuts low 1.5 60's that is very uncommon . once you actually start trying to drop ET it gets very tough just ask me LOL. Remember the numbers don't always convert from paper to real life :D

If I had 6900 HP, I better be able to run a 12.5 :eek:

For the guy who isn't hardcore, is running a LLY CC/SB 4x4, 4" exhaust, shim-mod, built trans, liftpump, at a typical dragstrip, the average is going to be about 13.2 @ 99 in my opinion.

It took us 475rwhp in Casper to run our first "tune-only" 12, which was a 12.85? but that was back in the days of stacking with harness boxes.

as far as hardcore goes, im at the track almost every week i can. I know i not a "big boy" yet still running a stock turbo but i plan on changing that down the road as money allows

i plan on running the hottest tune nick can give me so i figure i should be good for at least 530RWHP hopefully a few hairs more....i haven't reweighed since i pulled my leafs apart and ditched the spare. ive also never weighed it without the tailgate and tonneau cover. i should be able to get her down to the 6800lbs range hopfully but it is a fully loaded CC truck and i weight 200 so its never gonna be too great weight wise.

full list of mods are,
EFI by Nick
Banks intake with LBZ mouthpiece
straightpipe exhaust
ppe lift pump
caltracs
trutrac 11.5
only running 2 rear leafs per side and drop keys so shes on the low side
sleeves/braces

before race season starts i plan on also adding good adjustable shocks to help with the 60' i dont think 1.5 will be completely impossible (though unlikey) but i dont see hitting low 1.6's as being farfetched at all

plus i know being at sea level helps so i dont think ill have a hard time (least not too hard) running 12's its just how deep that im wondering. again i dont expect any magic i know its not an overnight thing but i would eventually really really like to have this thing doing mid twelves stock turbo

Once again i hope you reach your goal BUT 530hp on a stock turbo LLY is not realistic... there is only so much hp that your truck will allow sadly the LLY's in a tune only application is the slowest there is. Like Pat said 475hp is realistic... what elevation are you at? get a built trans run a 12 then you can see where you need improving... there are SO many variables in running well, hell even break in tolerances could come into play. You may have a "freak" truck or you have a dud LOL my buddy ran 12.56 @ 106 stock turbo LMM at as close to sea level as you could get... Matt sikdmax ran 13.3's with a stock turbo LMM with basically the same exact modifications. There are hundreds of these types of threads "What will I run?" no one knows truthfully

I agree. Like I said. Just running a 12 is a realistic goal. Anything below that is just icing on the cake.

Once again there are lots of variables... your local track might not prep there tracks for shit so good 60's might be tough. I have ran at 3 tracks now Redding for an NHRDA event the track prep was pathetic guys with drag radials cutting 1.7-1.8's when usually they are in the 1.5's.. The second was Infineon Raceway a decently prepped track but i have never been in the 1.'6s there. My preferred track is Sacramento on any given day i go out there and be in the 1.65's on street tires. Best advice i can give is hope for 13.0's if you run 12.9 be happy if you run 13.0 then you will be satisfied for your first time out.

Im at sea level....

so i though the lly turbo had a slightly larger compressor and could flow a little bit more air then the lbz/lmm turbos:confused:

i do understand that there are 1000x variables but im trying to dial this down fast as i can before i make the jump to a twin setup
