Right now I have a bigger cam, btr stage 4, yank ss4000 and full bolt ons (stock gears) in my c5. I run a 1.51 60ft 7.15 1/8th mile @93.75mph. Would I gain anything by switching to yanks pt series of converter or could I potentially stay the same or maybe even not run as good? It seems as if I have a strong running combo as is but I'd like to hit 6's cam only

 

I asked Dave at Yank the same thing with a similar combo and he told me no.

 

Thanks for the response, about what I expected but reading threads on here you would expect a huge gain

 

He flat out told me it wouldnt 60ft as good as an SS. He asked for shift extension i told him 1k rpms and he said Im good with what i got.

 

How high do you spin it? You might consider the PT 4400.
I love my PT 4000 and will be switching to the PT 4400 this winter.

 

Thats right, he did say i might gain some if I spun the motor to 7k+, which i wasnt interested in doing.

 

Whats your combo, rear gear, and tire size ?

Your 60's better than mine, but your ET is a touch slower.

I would play with your shift points too.

 

Like I said in my post, stock gears (3.15s) 275/40/17 rear tires, cam only ls1 c5, full weight, stock suspension. Whats your combo? I feel like for my mods its running good just didnt know if switching over to a PT4400 or PT4000 would get me just a bit more and maybe hit 6's cam only

 

Oh only spinning it to about 6600 by the way, lot of stock parts in the engine lol

 

Approx 10.5"x 26" tire....thinking better gearing would help

Tried shifting any lower or higher....6600 been it's best ET/MPH ?

 

Im not the one that tuned it so messing with shift points is limited for me. I wish switching gears was easy in a c5 I would give that a go as well
