Converter for Blown L99? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hey guys,

I have recently installed a whipple with a 3.8 pulley on my L99. CAI, headers...making about 550 rwhp. What do you ya'll think about a "looser" converter? 2,800 billet?

maybe go with something a little higher like a 3300 incase you ever put a cam in it

I just talked to Chris Sehorn from Circle-D last week about a converter for my camaro. I`m running a similar combo to yours and he recommended a 265mm version of their converter with a stall speed in the 2500-2700 RPM range. I sent him cam specs and a dyno print out. The 265mm is not on the Circle-D web site yet. you can email him yourself and get some good info from a pro.

askchris@circle-d.info

I`m sure he can give you some great advice and the price was right also.

Do it. I just got one in mine. (No blower as of yet)

lexlueger · 09-27-2011, 09:09 AM

Any quality converter will do. Precision, pro torque, fti, yank, circle d, etc etc etc . I went with a Precision 2800. I'm supercharged and cam'd.

I'm a Cammed automatic that has had a LS3 Conversion and im running a 3200 and its dam near stock feeling.

Chris@SPMC · 09-27-2011, 11:21 AM

We have done a few 3200rpm Circle D Converters in Gen 5 and they really shine at the track.

Tyler@ExtremePerformance · 09-27-2011, 11:24 AM

We use FTI converters. Call Greg he can set you up a nice 3000-3200 would work fantastic!

I have a Pro Torque from Jannetty and it is perfect, The convertor is 94% efficiant which is unheard of. My precision that I took out was only 84%. Its like night and day.

And the car is 4 tenths faster

Protorque is that Unheard of Mastermind of Torque converters, I have been working with them since 1998.

I have used all major brands and IMO No one builds a better more efficient converter.

Protorque currently Holds Many ET Records in Promod, Outlaw 10.5,and drag radial and many others.

Take a good Look At Protorque, SuperchargedSS has one in his car for quite some time now.

i also have the Jannetty/protorque stall in my car. it works very well and did'nt even need a retune for the transmission.
