What procharger would you recommend? I like the idea of just o/r exhaust, a circle d convertor and a procharger and that's it. (besides whatever supporting mods needed. Bap, oil pump? etc.)

D-1 at the very least. :favorites13:

My P1SC is still running the canned ProCharger tune set for 7 PSI. Right now I am working with getting a dyno session with Maximum Velocity for a Lund Tune. I have some issue with drive ability under light throttle that I am looking to get fixed. As for the RPM range, you can feel the centri really kicking in between 3-4k range.

To answer the question about boss vs gt, the cranks are exactly the same save for the balance job. The pistons are a mahle brand forging and the rods are an, IMO, weaker then stock gt, very thin rod. Also there seems to be assumptions that the boss rods and pistons are lighter, when in fact they are heavier then the gt stuff. I will tank pics and give weights tomorrow when I get back to the shop but IMO I would say the gt stuff may be stronger.

<620 rwhp you should be fine unless the ringlands fail. More then that you are just on borrowed time IMO. Another major weaklink is the block for you crazy hp guys. The sleeves are extremely thin, I would not recommend more then 850 rwhp on a stock block. More then that an you are just on borrowed time.

At this point I have built about 15 of these coyote engines with 4 in the shop now waiting to get done. I have pretty much seen every different failure and each time it's either number 8 failure a ringland fails or just too much damn power for a stock short block at 700+.

Take it for what it's worth, this is just my own hands on experience with these engines.

Thanks for the quality post. Very interested to see comparison shots between the internals of the GT and Boss. Thanks for again comfirming the GT and Boss have the same crank. You stated that the pistons are a forged Mahle, is that for the Boss, GT or both?

Start with Merlin, then JDBishop.

Fastest I've been was 11.6 at 124 with 20" 555rs. 1.9 60ft. Just you give you an idea. And I am having to shift into 5th before the trap.

To be honest, this car has never been to the track as the current combo is all new. But you run exactly what I feel the car is capable of, so utd be a fun race. Dead stop on the street?

I'm game. I don't know what I dyno with the new tune but I'd imagine it's in the 560 range.

Lol it probably is for now. After E85 it will be a little different.

I love your car. Everytime I see it makes me think twice about no body mods. I'm sure your car will be a good run for Strokd's Vanilla Ice machine.

Thanks Steve. Trying to keep it subtle. I keep going back and forth on the CF hood vents. Once the lower grille comes in I'll be just about done with exterior mods. Then back to motor.
