Torque Converter vs Nitrous

[zraffz]

I was talking to Lloyd Elliot earlier about a cam for the motor I'm building and I overlooked the torque converter.

He had suggested the 234/238 .611"/.611" (that dynoed 413whp and went low 11's behind a 3,600 stall on LS1Tech).

His other suggestion was a huge jump; 236/244 .608"/.608" with a 4,000-4,400 converter.

Motor build is a 357 (trick flow 185cc as cast, probe -4cc 2618 nitrous pistons, callies h-beam rods, stock crank). Still not 100% certain of how much nitrous I want to run but it will be in the area of 200-250. I'm aware I will need a nitrous specific converter with balloon plates. How is the nitrous going to affect the torque converter? (If I were to run a progressive controller, would it solve any converter issues)?

Get a custom made converter and dont worry about it. Call Circle D or PTC and explain to them everything they will spec one for you.

If you wanna go fast, you hit it will nitrous off of the line. This will raise your stall speed significantly. You can't have a motor that works great n/a and on spray, pick one and call a converter company. I would think the 236/244 would work better with a large hit but I don't sell cams for a living.

This.

They will match you up with the right part.

I understand that but wouldn't a smaller shot off the line keep the stall speed down a bit more?

Sure, but you aren't going to stick with a small shot
