i was wondering should i stay with the sequential system that comes with the 3 rotor from pettit racing or should i put a big single ,or keep the primary the same and just upgrade the secondary .?How much lag will i get out of a big single ?when i get the engine i think the boost is at abot 10 psi with 560 hp/460 tourque.im looking to make my car in low 10sorhigh high9s on the track on the sreet im looking for really good all around performance. oh by trhe way i have an 89 Tll .

Well I think you would have plently for power anyway you go with the turbo setup. It depents on what you are going to use the car for like a single turbo setup would be a good setup for roadracing and dragracing.
Twin-turbos would be great for auto-x and so on. I think that you would not have much of a problem with low-end on a 3-rotor engine. So going single would be better due to high Hp you can make from it and a simple build setup.

thanks for your help .i was thnk of doing a little bit of drag just to see if i can get my car into the 10s or high high 9s but i also would like to do some track. i dont think that ill be able to do alot of track but i plan on doing it .will there be alot of lag with a single because my idea was that going to a sequential system would take away most of the lag. in my Tll right it is stock and theres alot of lag untill 4000 then it goes its still slow but thats the stock turbo from 89 so are the new ones alot better ?also do i buy ball bearing or tradional?
