Hi!
I am not pleased whith my car after mods and wounder if it can be the stock fuelpressure,I have not yet pot on my fuelpressure regulator and finiched the ultimate tb mods but it will come soon.
So my cuestion is if you think it can depend only on fuelpressure and a low airflow that my car puts out about 220 hp at flywheel (8.3 sec 0-60).
My engine combo chould be able to put out up to 280hp at 600cfm.
Do I need a 454 tbi rigth away or?
Thanks!
Anders

 

I don't think you can get 200 more cfm from your stock tbi. a 454 tb sounds like a good idea. I am not a pro but I've done my share of engine tuning, and I would say 600 to 650 cfm would give you the best results even with a few more modifications. Any one care to add any thing to this is welcome. I wouldn't want to steer him wrong! Good luck!
