Help me hit 10s n/a on stock heads!
I just recently hit my goal of 11s na with a stock long block. I am now shooting for 10s na on the same stock long block but need some input on how to get there. My car is pretty consistent that for every 1 tenth in the 60 I pick up 1.5 in the quarter. With that being said I do believe I can run some 11.60s with a 1.50 60ft just like it sits.
Questions: How much weight does the car/driver combo need to loose to hit 10s na with stock long block?
How much more power will be needed along with the weight reduction to hit 10s na with stock long block? Ex. Car looses 150lbs plus 30hp should go 10s na etc.. just an example..
Please give any suspension tips as well for I am still running stock springs and shocks.
Car with driver - 3550
Long Tubes
ORY
Magnaflow Catback
Torquer 2
LS6 Intake
Lid
Stock ported TB
Stock Maf
Full suspension, stock shocks and springs however
9 inch, 411, MT ET Streets, 6spd car
Leaving at 4k my first 11sec pass was:
60ft 1.73
330 4.99
1.8 7.68
mph 92.05
1000 9.98
1/4 11.92
mph 116.82 (best mph 116.99)
This pass was in 64 degree weather, we have some 40s coming so that shouyld help some along with some 5k launches I hope.
Thanks,

Thanks, just curious on the timing tip. I am new to tuning but what I have seen as far as timing goes is this. Keep adding timing and fuel until you start to get knock or stop making power. Does that sound about right?

at the weight (3500) i dont think you'll be in the 10's .....i was at 3300 with the same hp and i ran 11.4 @ 122 with an ave 60ft of 1.60 .... i converted to a 402 ci N/A putting down 500rwhp dropped some weight and got my 60 down to mid 1.5's and ran consistent 10.6's @ 129-130 mph ....

im right at 3000 give or take a few but the key is the m6 ..... 1.5's sucks imo ....im converting to a th400 with a 5000+ stall trans bk ,2 step more weight reduc. ... my goal is to go in the 1.2's 60ft so i should be in the 9's ! im tired of going through clutches ,slaves ect ...i really think with your weight 30 hp wont cut it imo..

i would recommend maxing out the mods you got now, get a RAM AIR like a FTRA or a sux2bu setup, get a 25% UD pulley, make sure you half shaft the TB you have now (i even half shafted the half shaft on my throttle body, 1/4 shaft i guess lol), a cutout in the magnaflow catback will give you probably another 5rwhp...just a couple of things off the top of my head...that is why my car runs so strong it is in the little details that add up...

my car on radials goes 1.5's feathering the clutch ....now im going to a 2 step ,trans bk, 9 in converter w/ a 5500 stall going to a 29 in tire loosing more weight ( 2900 lbs min goal) ..TSP h/c car goes 1.2's with less power & tq than im making and a 150 lbs lighter so if i can go high 1.2's or even low 1.3's i'll be happy
Larry from speed inc is doing the setup and he's confident the car should do it on motor....

I ran 10.7's at 126 with mildly ported heads and 3400ish race weight. Had a crappy 1.53 60' and not so great weather but car ran well.
I think you will need to lose some weight and get at least a 1.50 sixty. As far as the tune, race gas didn't do much for me, car only liked 28* of timing and lost power after that. Like said above though, every cam/combination likes something different. Suspension is important as well.

i put down 422 and got 10s with about 3250-3300 raceweight...it is all in the setup and suspension...

Thanks man, haven't looked at the inside of my tb in awhile but is there enough material left to hold the shaft on good after doing this mod? I'm trying to visualize the thickness of the blade itself, I remember it being pretty thin but could be wrong.

BTW, my FAST 90/90 setup was good for a couple MPH and a tenth over the LS6 for me, just a thought. PS delete and EWP was worth 1-2 tenths as well. The Neal Chance 4800 stall worked awesome. I think the complete package just worked well for me, could of easily got a 10.50 out of it with some weight gone and a little more tuning, but sold it all for the new turbo setup.

Your car is very inspirational, but what do you think you would run with a lower converter like a 3000?

Dan, with the PS delete did you just bypass the pump with a shorter belt or delete PS all together? I'm still not 100% sold on the EWP but statements like yours makes me think twice about that purchase. As far as the intake goes I'm deffinately going with something better but I'm not sure what route. I guess I'm still window shopping and waiting on some real world numbers out of the Street Warrior and almost forgot the most important thing from the SW and that's an actual release date! LOL
Thanks for the help!
