Road Runner platform N/A potential

Gentlemen,

Curious here. I seen that the modified JPC Coyote N/A motor made 507 rwhp.

What are these motors overall capable of?

If someone ran E85 or the FTW fuel in a Road Runner based engine and put 13:1 pistons in there, used the CJ intake, did a stage 3 port on the heads and swapped in stage 3 cams, what kind of N/A power would you be looking at?

525? What is the limit and does anyone know of any Coyote/Roadrunner motor that has made more than the 507?

I know simply slapping a blower on would be more cost efficient, so I'm not asking about that. I was just curious if anyone has ever wondered what the ceiling will be N/A for these motors in the future.

Thanks,

In for replies. The CJ intake a supporting mods costs as much as a blower! But I do like it.

We tuned a couple of these bad boys with a pretty mild custom grind cam. The results were around 550whp if I remember correctly.

Once these manifolds become more readily available we will be able to help you guys duplicate our winning Cobra Jet combinations : )
