On a track you drive out of the corner under power. While a laggy turbo that comes on hard all at once will cause a problem, so will one that jumps around like the stockers on that graph.
Low end power is hard to compare on dyno charts. If the guy driving the car starts from different RPM for different cars the low end won't be comparable. If they ALWAYS got on the throttle hard at 2000 RPM it might help.

gotta go back to teh drawign board...
stock sequentilal system should be of no problem on teh track unless
u donno how to drive, part throttle doesnt affect the transition, and if u are full thrtolle in mid corner u are not doing somethign right. [/quote]
Wow, you really love those twins. You might want to look at the other Forum and count how many posts pertain to boost problems. Probably more than any other issue. You might want to ride in some cars with single turbos. The stock twins have no many issues i cant even decide where to start. other than control issues which are a huge problem, The turbos themselves make so much heat at other than stock boost levels they are engine killers. Also dont forget how nice they crack. Most sets i have seen. Even low mile examples all cracked up. As far as driving goes, when most people race they keep the rpms up and the power is linier at higher rpms. If your still driving around a race track at 2k rpms. ( I still cant understand this argument) then you might have some kind of issue. [/quote]
i have benn in single turbo cars, the only thing i liked was the AMOUNT of power which is still i think useless amount.

Your right its not for everyone. Just 99% of people I know who Like performance cars, More power consistantly and reliably is the holy grail. Single turbo offers these things. You dont have to get a Greddy T-88 or a Apexi T51R or Garrett GT42. There are smaller Units that provide both power and reliability over stock twins. Most of the Fd's still on the road with stock twins have control issues. Even fixing the control issues (if you can track them down without replacing everything) doesnt cure the typical high mile examples with cracked manifolds, worn out cartridges and used up oil seals etc. Many people try to rebuild these with mostly poor results. Its been documented by several experts and Rotary tuners that the best mod for both heat reduction, powergains and performance reliabilty is replacing the stock twins with a single turbo. Size is something that is considered when you decide what will meet your needs. The fact that you gain ALOT more than you lose with the conversion is already well documented. For many of us Power Freaks we want a huge turbo without sacrificing all of our Low end power for street driving. Thats why Ball bearing turbos and the Garrett GT3540 has become so popular.
