Was wondering what should be a limit of boost for this turbo. Some guys just use it to about 25lbs, that was where i may stop the turbo. But some have been over the 30 - 40 pounds range.
Dusty, I looked at your timing suggestions and this what i am up with for this box, it can take out 1,2, or 3 degrees and start at 0,1,2,3,4, or 5 pounds. It can take up to 15 degrees out of total timing.
With 34 total timing it will be at 19 degrees at 19 lbs.
Meaning from 19 to 25 or whatever pounds the motor would be at 19 degrees timing.
So what is too low of timing or this is the best solution for the exterme temp from the boost. Or will it be a dog after all that timing coming out.
malibuick231 what is the higheset you take your s480 and what is your launch boost and timing also.
The car will still run fine with 18* of timing. With the cast heads I'd be looking at no more that 22* at 30# of boost so 20-24* at 20-24# of boost will be fine on C16. A S475 on your motor will probably only make 15-20# anyway. A buddy had a 406 with 75mm with AFR heads and could only make 16# at 6500 rpm.
