Swap 3406c to a C-15 Acert

man id throw an acert crank in that C model some low compression pistons set of 3408 nozzles and build it up right and have the best of both worlds.

if that c model is pushing 600 ponies itll have plenty of torque too.

 

My BXS puts up 72psi of manifold pressure and will run almost all day on the cruise at 137,000lb gross and gives me 5.2-5.5mpg. It tows loads over hills at the same speed my last 3408 did so i have no complaint with the twins.

 

If I was going to delete the IVA's on an Acert I would delete the precooler and leave the twins.

 

Myself i wouldn’t do an IVA delete on an Acert unless it was single turbo’d first. I haven’t deleted mine because i still have the twins on it. Acerts were designed around Miller Timing, as a result they have an 18:1 piston. That ratio with 40-50psi delivery air compressing on closed intake valves seems like a good recipe for head gasket problems to me. That said, i do know of a couple that were coverted to single and deleted that run great.

 

They are still 18:1 when you delete the IVA's your begging for trouble if you dont put the 16:1 cylinder packs in it. Though I agree run till it gives trouble then put the lower compression packs in it to spread the expense out.
