Hehehe...good one.....also agree.
The seq-system is an awesome setup when working properly. Meshing the gas @ 2k rpm and having full boost(~12psi) within 200-300 rpm is nice.
Many like that feeling of early boost but keep in mind it's only one turbo working and once you start running higher boost it becomes problematic.......alot more heat and the fast that everything happens faster...such as actuators opening and closing during transition.
Been running non-seq and will never go back.
-I get full boost(17psi) 3.5-3.8krpm in 3rd.
-HP curve is linear...feels like a single
-less gizmos operating on the manifold/intake
-at lower rpms heat is shared with both turbos rather then w/ primary one
-exhaust is always flowing thru both tubines so when I hit the gas they will spool up a bit faster. With seq-system rear turbo will only see exhaust from a certain rpm and primary turbo has to generate at leats 8psi before the transition starts to happen. Back when it was seq if I meshed the throttle @ 4-4.5krpm on that transition window it would have more lag then the non-seq setup.
-non-seq is a bit louder
-if racing the motor I never spend anytime below 4krpm so non-seq is ideal.
-at higher boost (14+) the lack of hoses/solenoids is a plus with non-seq.
So if running ~14psi or less and the seq system is working good...leave it alone
For those others running more serious boost and racing the car non-seq is the way to go.......my opinion.
>SPOautos had full boost non-seq by 3K rpms <
What's full boost??? if higher then 15psi I doubt it very much...because his dyno did not reflect that.
Full boost by 3krpm means it spooling in the 2krpm range where there's simply not enough exhaust heat/pulses to spool twins (upgraded or not) in non-seq mode even if it was ball-bearing.
