I'm upgrading the rear differential to the Puddymod Stage-3 with a Carbonetics 1.5-way LSD, which gear set would you choose?

Car will be running a PTuning Turbo Kit w/Built Motor......Horse Power target is 465 - 510.

Anyone with specific experience with the 3.90's is also welcome to post up their opinion as far as why / why not.

Interested in hearing from guys who have had turbo kits on their car and have at least 425+ HP

Thanks a bunch

 

If you can tell me how to contact and organise a puddy diff rated to 1,000 bhp that has a rear gear which'd do over 200mph, i'd be very grateful.

 

1. pm user 'puddydad'
2. Pay him
3. ????
4. Profit

 

Tried, no response, still wanting the product. I will retry the pm.

 

I can p.m. you Ben's e-mail and phone number.....its the easiest way to get ahold of him.

When I talked with him, he said the taller gear sets available through him are either 3.63 or 3.90

And you're talking about his stage-4 build which will include a Carbonetics or Os Giken 1.5-way or 2-way diff....once he's done it's rated for 200,000-psi but its gonna cost a $$$$ to get there.

 

His user name is S2KPuddydad.

I had a stage 3 puddymod diff with 4.07 gearset and made 490hp at 19 psi. Diff was awesome. I was not drag racing though, so couldn't tell you about needing a taller gear to get to end of track, etc etc. It worked very well for a street driven 500 hp S2K.

 

Did you ever feel like you went through the gears to fast.....

 

Morning guys, i'd just like to extend a large thanks - puddy dad's been in contact to get the ball rolling.

 

At 500 rwhp the 3.90s are a good choice. It hits 135mph in 4th.

 

Do you have them on your car?
