The spool time shouldn't be any different. The big difference is in the first couple of gears. 3:90s you may have not seen boost till 3rd gear. With 3:73s I wouldn't see boost till the top of 2nd going into 3rd. Now it's boost in all gears. Turbo cars don't make power till the boost shows up. So why would you want a half powered car till 3rd gear in a race. Now with higher gears you won't climb the rpms so fast and will be in the boosted power band longer. It will also be easier around town driving.
It like this 3:90 may take 3seconds to rev up to 5k. But you also didn't see boost till 3rd maybe so that's only leaves you with two gears in a normal race which gives you 6 seconds of half power and 6 seconds of boosted power. Now with 3:27s you will get 4seconds till it reaches 5k. And boost in all gears. Now you get to use all boosted power for 16seconds in a race. Which it should be well over by then. They will make all the difference in the world.
Hope that makes sense. Goat I hope to see you on the 15th @C&S.
