We typically recommend 1 7/8 until 9-1000whp.. the 2" are fine at a tad lower levels, but an unnecessary addition. You have to lower the motor/trim the studs for most 2" applications. If you ever end up wanting to go with headers (I saw the comment on the 3/36k warranty), checkout our Lethal...

I've got the stock OPG's and sprocket in my manual premium GT and on my 10 speed DH. The DH is most likely making over 1000rwhp and has been raced several times without any issues. With that said I do typically recommend them to customers as they cost a lot less than an engine rebuild.

There are a few different paths you can take for an exhaust upgrade. You can swap out your resonator for a midpipe, get a catback, or an axleback. It is popular to get a full catback, especially for active exhaust cars, as you can keep the valves closed but still have better sound, and open the...

I've owned and raced several 10R80 cars over the years with 2 of them over the 1000rwhp mark and one in the 8's. My 2018 GT with the Whipple 3.0L that eventually went 8.64@157 had zero issues with the stock 10R80. It was only at the 900+ level that we were recommended to upgrade the steel and...

The stock upper for the 6 rib setup is a 3.85" I believe. If you go with a 20% lower and a 3.75" upper on a 10 rib setup I believe you'll be in the 18psi range. Every 1/8" in pulley size changes boost by about 1psi. You're going to need to run better fuel than 93 and a fuel pump booster like...

There's really no point in running a 120mm TB on a stage 1 let alone a stage 2 making under 1000rwhp. For one the stage 1 calibration is throttle and speed limited. So no matter how big you go on the throttle body or how small you go with a pulley the throttle calibration won't allow you pass a...

I put a RSA stage 3 transmission in my darkhorse as we are making over the 1000rwhp mark and know the stock steel and frictions would be at it's limit at that level. I think if you keep it under the 900rwhp mark the stock transmission "should" hold up pretty well. If you plan to go above that or...
