My car has few mods now, Whisper lid and fast toys ram air. Having Hooker LTs, custom Y pipe, and a cutout installed next week. I have been looking at the spreadsheet on Yanks website. I plan to have heads and cam on the car soon, summer time hopefuly. I do not plan to N20 on my car. My question is can I get a convertor to handle the power of the heads and cam car now, with just intake and headers? I really am concerned if I can have to much convertor and not enough car so to speak. I am not concerned about streetability, drag racing is my main concern. I am new to convertors so I am looking for an tips and advice I can get. Thanks in advance

 

with out knowing how aggresive you plan on going with your set up. I can only make generalizations.
Converters that have proven themselves as both stock AND H/C performers?

Yank Thruster Pro 4400 (easily the number one choice)
Vig 3600 (really closer to a 4300 converter or so)

either of those two would get the job done in a the parameters you have given... with the nod going to the TP4400. It works magnificently mated with a stock motor OR a heads/cam motor.

Thats my two cents.

 

well stated, JC

That is the info I wanted to know. The Yank Thruster Pro 4400 was the convertor I was looking at to fit my future set up, but was not sure how it would work on a near stock car. It looks to be my number one choice right now.
Any other info?

 

What is the difference between the Yank Thruster Pro 4400 and Yank Thruster Pro Extreme 4400, performance mostly?

 

I believe that the Extreme series ‘verters are for N2O and blower/turbo type applications. Their rated stall is meant to account for the huge increase of torque with FI. I think an Extreme series ‘verter will actually stall much lower than rated if you’re running NA. Some one correct me if I’m wrong here...

 

They are also 6-lug units and have Yank's Posi lock clutch setup. You're right, they are inteded for P/A applications

DING! good answer <img src="gr_stretch.gif" border="0">
You can run an extreme NA too. They tend to actually be a little more efficent then the non-extreme converters.

Buzzzz wrong answer <img src="gr_grin.gif" border="0">

The extremes will stall to their rated speed under NA and stall higher under FI load. They are designed knowing that high torque will be applied and therefore they stretch out less under the FI load. Their internals are also designed to withstand the extra torque from FI.
