New best at track last night
New best at track last night This is a new best for me. Previously 11.77 @ 119.81 mph. This tight converter sure makes it hard for a good launch. Any too I need to make a few changes to my tune. Recorded quite a lot of KR in 2nd and 3rd gears which had not showed up on the street. IATs were so high probably the reason. 117* at launch.

Thanks NoTractionLS1!
That 1.84 60' was with no spinning. I don't think I can do much better with this converter. You just can make power at 1600 rpm. I'm going about 26-27 mph before I start making power. Lots of time lost.

Larry is too humble to reference his old 10 second NA 4th gen and his experience with converter and sticky tires.
Larry what do you think would be a good size converter for those LS3 cars for all around driving but getting down in the 1.6's on a radial.

Verdad Gallardo Yes, I sure enjoyed that 98 Camaro. With my PI 3600 stall and 122.6 mph speed it ran a 10.77 et., 1.44 60'. Would think an LS3 with 122.6 mph could do the same.
And don't forget my 10.30 @ 126.62 mph, 1.39 60' 88 Mustang. What was a fun car turned out to be not so fun on my last pass. Crash!

i have the yank 3600 with 3.42 gears which drives good on the street and it pulled a best of 1.51 on stock suspension. in decent weather (and i also have coilovers now) it pulls 1.55. im thinking with the right weather and tire i maybe able to pull a 1.49 which would be awesome.
good luck with your choice if you decide to do a converter

I dynoed when I had the Z06 manifolds and put down 427 hp/423 torque. Not sure how much the headers improved my numbers if any but I should be able to run some 1.5 60' then with the same gearing and converter that you have. Not sure I want to go with a 3.42 gear but a converter might be in my future.
That's right, you had Z06 manifolds before... what prompted you to swap those out to headers... Just looking for more power? Is the engine noise louder now (tickety tick ).. ?
My 427 rwhp was with the gutted Z06 cats. The sound is about the same with my high flow cats and headers as the Z06 was with gutted cats. The Z06 w/cats is quieter than my high flow cats. Either is very acceptable with this NPP exhaust however. No tickey tick sound.
So you are running what size headers? Into Z06 exhaust and stock Z06 mufflers?
I'm wondering what size converter would get the cars into the very high 1.5's and low 1.6's and still drive good... 3200... 3600?

I have Kooks 1 7/8" headers running into my stock C6 NPP mufflers.
