On a full-drag setup they're terrible...which is likely the reason the newest Evo turbine housings from FP are all single-scroll. Twin-scroll for spool, single-scroll for flow; drag guys don't care about spool at all because of all the launch control and anti-lag functions that are implemented into today's tuning platforms- and once the turbo is lit, it tends to stay that way.I've never been fully convinced of the efficacy of a twin scroll setup on a maxed out setup for drag racing.
I dont have dyno or track numbers on it yet but i have some spool numbers that may interest you.
I'm on the 1.15AR twin scroll t4 6466 and i dont see 30psi until 6150rpm. 37psi by 6750rpm. I'm hoping the 1.00AR will bring that down to 5500rpm. I'm a 2.0. Guys with the t3 housing are seeing spool a lot sooner maybe 40psi by 5700 on a 2.0 but probably will also top out sooner due to the 3" outlet. The t4 turbine housings havea 3 5/8 outlet so the backpressure is going to be less. My friend with the 1.15AR t4 twin scroll 6466 but with a 2.3 auto is seeing 40psi by 5500, he also tried the 1.32AR and said he said 100rpm more lag for him and hes an auto same 40psi.I'll be dynoing my car this winter on both housings on a mustang dyno at vivid racing arizona.
Thing hits rediculesly hard though, and i came from an hx40.
Here is the sheet with the Magnus 92mm Crank ans portet head.
The sheet is with only 32 psi with the same psi like the 2.0l sheet make the car over 1000 HP but i have not a print.
