hi ppl,



would a 1/2 bridge FD stay alive when the max is 15PSI with the following specs and mods:



- stock twins non-seq

- large Pettit ic

- open intake

- open exhaust

- Pettit Unlimited

- S-AFC II

- 2x850cc pri

- 2x1200cc sec

- Blitz Dual SBC



so i want to tune it for now with the Pettit and the S-AFC II. any ideas if this is possible?

searched here and 'there' but found nothing

You should consider getting a single turbo with a 1/2 bridge motor

i ran a 1/2 bridge (open intake and exhaust) w/ NS twins using a Haltec and 2 850's and 2 1600's with no problem. Not sure about using the 1200's though. As far as tuning it useing the afc and the pettit...... i don't see any issues. I would go bigger secondary injectors though.

GreyGT-C,



how was it with the stock twins and a 1/2 bridge?? did you like it or is the drivability bad?

You are chocking the exhaust using the stock twins

You have big exhaust ports know. When using the stock manifold the exhaust can't breath like it would with a tubular manifold. I am just saying the stock twins is not a good combination with a half bridge.
