suggestions to get me to 12.50s
OK so I'm looking for suggestions to get my car to the 12.50 range so 12.599 or faster.
currently I have ran 12.72@110.98mph with a 1.98 60ft. Car is a 98 z28 m6 with a stock lq4 longblock.mods are longtubes,ory,ported TB and Maf,cutout,free mods,home made ram air(not sealed to air box),slp lid,& a frost mail order tune for nitrous. My timing at wot is 21.5° and I tried the iat resistor mod to get an additional. 1.5°but it brought it down to 20°. I'm leaving at about 4500rpm on street tires slipping the clutch a tiny bit and have no tire spin.you guys think there's something I can do for cheap to get that last .2 tenths?
I wanna do it n/a and for next to nothing.
Thanks joe

LOL yeah I know. I am going to be spraying the car soon.times are n/a. Plans are to spray eventually but now that I'm close to 12.50 I have made a goal of it. I'd buy drag radials but I'm worried about breaking the ten bolt. Traction hasint been a issue,but I'm sure the clutch slip is helping a lot. I would retune the car but since plans are to Turbo it in the winter I see no real big point.how much does a tenth off 60ft typically help et? I think its mostly maxed out in current form. Maybe I can eek out another tenth but that may be all it has

Trust me you are going to have to get a new rearend because that ten bolt is not going to last you very LONG. As soon as you put some DR on the back you are going to brack it . You might get to make a few good pass's but trust me its not going to last to LONG.

LOL yeah I know then bolt is not a strong diff. I can't justify since I go to the track 3-4 times a year and the car is a street car. If I brake it ill buy another $100 ten bolt.
Rear end has sofar held up to 30 bottles of nitrous on a 125 rwhp shot with the old motor. I don't deny there weak at all,but the cost is not worth it

pull some weight. front/rear bumper supports, back seats, front swaybar...exhaust past the y. and anything else that isn't necessary..
or get better tires and hope you don't hammer the drivetrain too much. the a4 cars do much better, simply due to so little drivetrain shock.
what's the da where you're racing? your goal may be as simple as waiting for better weather.

Was thinking of gutting the car temporary to run the number.how much weight you think needs to come out per tenth? As far as da I am unsure. It was about 68° with maybe 75% humidity at 300ft above sea level. I did hot lap the hell out of my car. It seemed to get faster and faster.I made 20 passes in 4 hours. Maybe removing weight and running my car cold ish may do it, plus maybe sealing my ram air
