The SL55 accelerates slightly faster up to about 75mph than this one starts to pull once the turbos start to get at their peak of spooling
Seems like the SL55 smaller blower pulley, larger throttle body, and cooling mods make a huge gain without threatening the integrity of the engine.
can grab an extra 100hp or more without much work.
Probably need an additional oil cooler (ala P30?)
At that point the exhaust starts to choke it - bypass pipes?
