The main feature of the new Pacemaker Comps is a larger 1-5/8 primary pipe over the original Comp 1-1/2's.
Don't let rwkw losses worry you with high stalls,as Casper says the benefits far outweigh the losses.It's all about torque multiplication & thats what a high stall does "multiplys torque".This is what moves the cars mass from a standing start & also allows the engine to work in an area where the engine is starting to produce strong power & torque.Unfortunately the downside is a loss in RWKW's due to to the slippage required via different vain angles,stator designs etc to make them work.Rule of thumb on most cars is a 8-10rwkw loss using a 3000-3500rpm convertor,a 4000-5000rpm version may show a loss of 12-20rwkw's.Most high stalls have anywhere from 5-7% slip with a poor design showing as high as 10%.A manual transmission for example shows zero slip & a stock convertor also shows very little.The race track sorts out any worries when it comes to this issue.RWKW's aren't everything.
So in a nutshell don't rush out & pull your high stall convertor out if you have one,that is of course if it's correctly matched to your car.
