I went to Huntsville Dragstrip tonight and my previous best 1/8th mile was 7.8X at 88.XX with a 1.77 60' I believe. Tonight I managed a 7.68 at 89mph with a 1.66 60'. I feel like this isn't right... I went from running a 7.8 with a 3600 PTC converter with stock cam and 3.23 gears on NT05 tires. I now have a Tsunami cam with a yank PAS3800 and 3.73 gears. I have MT ET street SS's and LCA relocations coming in the mail this week, but I feel like I should have a higher MPH and lower ET than that, even with the NT555s I'm currently on. My shift points are at around 6300, would bumping them up to 6700-6800 help get that ET down and MPH up? It's kinda disappointing to only drop .1-.2 and pick up 1mph after this big of a cam swap and swapping gears... Here is the dyno sheet

You definitely need to be spinning it higher than 6300 !
That also is a tighter converter for boost and nitrous so you probably are not seeing the shift extensions you would with a n/a converter.

Your shift extensions are probably around 5,000 rpms, maybe, where you are only making about 310 whp.

Spin it to 6800

As mentioned above definitely spin it higher. Weather it's a stick or auto, a cammed LS1 needs to rev.

Tight converter, low shift points and big cam... I am not far from you, do you ever run at lassiter, steele or holiday beach?

I'm going to have Lane crank up the shift points. It should be trapping so much higher.

97TAsom

I've ran at Lassiter and Steele, never heard on holiday beach

97TAsom

Yes it does and I can tell this cam wants to rev high.

FWIW, when it shifts at 6300ish, my RPMs drop top around 54-5500. So looking at my graph, I should be making 350+whp the whole time after I leave the line.

As others have stated, should be 6700+ shift points and not a great converter for the setup!

97TAsom

Right, I knew the converter wasn't ideal for a N/A application but I thought it should still pick it up quite a bit. I'm just waiting to get this nitrous kit ordered, then I believe I should be able to run high 6's to 7.0's on a 100-150 shot

Nitrous will definitely make that a very fun street car!

97TAsom

That's the plan! But it'll still be N/A....

You’re not far from me, you definitely need to up the shift points. That’ll pick it up definitely.

I am, I'm going to move them to 6800
