So I blew out the front seal and did a blow down test.

Im guessing got a broke ring land. Got the head off that side. Bore and even top of piston looks good. Should have piston out tomorrow.

If it is I will post up pics. So Im gonna forge it while its down.

Question should I go 10 to one like the lt4? It should be more forgiving an easier to tune I suppose but at what power cost with 12 pds of boost

this is at 660 rw

If you’re planning on upping the boost, definitely drop the CR to 10:1. If you are always going to run E85 or are staying at that power level, the motor is technically more efficient at 11:1 and you could stay there. Just my 2 cents.
