I was out doing a little tuning and decided to video this. Let's see what you guys got. I think mysetup has pretty fat torque band for a 346 with unported heads and small cam. 3.42 gears in 4th gear.

50-60 = 1.71 seconds (2300-2800 rpm)
60-70 = 1.562 (2800-3250)
70-80 = 1.576 (3250-3680)
80-90 = 1.962 (3680-4180) 3 degree's knock retard @ 4000 rpm doh!
90-100 = 1.735 (4180-4640)
100-110 = 1.665 (4640-5100)
110-120 = 1.636 (5100-5550)
120-130 = 2.137 (5550-6000)
130-140 = 2.73 (6000-6450)

All in all pretty linear acceleration I would say, and as you can how big of a factor wind resistance becomes above 120 mph.

Thats some serious angle of the dangle **** man. Car pulls hard though!

 

I gained a lot going from an LS6 intake to a ported 85mm Fast I did and installing an underdrive pulley. The car pulls so much better and looking at old logs I have picked up quite a bit. Should be over 430rwhp / 400 tq no problem now. Not bad for unported 243's and a custom 224 cam

 

your SES light is on

 

very nice, 45-140 in one gear haha hows the traction in 1st, 2nd, 3rd?

 

Correct, Open loop speed density with maf delete. MAF failure set to Mil on 1st error reported. I suppose I can shut the light off, since I know it's in SD, but I have not done so yet.

It's not the greatest, 275/40-17 Nexen tires. Will blow them off if I hammer it in 1st at 2500 rpm and if I shift hard into 2nd the car goes sideways laying rubber up to 70 mph. My Midwest Chassis 9" with 4.11's will be in shortly, I will post more vids with the 4.11's. Traction will be a lot worse but now I won't have to worry about destroying the 10 bolt at the track with slicks.

Also with the cutout open I gain 17 hp / 13 tq and it was closed on that video. Here is a little burnout with cutout open when I had the LS6 intake.

nice pickup, that burnout was sick lol

 

Anyone else care to post a video with a 4th gear punch and 3.42s? 408s, prochargers, turbo come on I want to see the difference.

 

I'll post up a video with 3.73 with HCI for you soon

I love the burnout!

 

I remember that burnout video. That vid is great.

 

I have to upload the crappy video somehow. No 3.42's though.
M6, 347, d1sc, 4.10's, 700rwhp. 4th gear 70-110mph in about 3.8 secs.

 

Be sure you factor in the fact that as you increase speed, the resistance against the car increases exponentially. So, while your 50-60 and 110-120 times may be very similar, your car is doing a LOT more work in the same amount of time at the higher speed. In short, this isn't a very scientific test.

 

Yes I do understand that. This was far from a scientific test, more of a comparison with other similar geared cars. Apparently no one wants to post up the acceleration of there setups (under the curve, below 5000 rpm).

 

that burnout was sick..the best my car can do is light smokin the passanger front tire till 30 haha

 

Well guys I have confirmed my suspicions of my "power under the curve". 365 rwtq @ 3000 rpm, thats 30 ft lbs more than my bolt on car made at peak torque! 414 max torque now
