Hoping to wrap up the build here in the next couple of months. Just curious on what you guys think it will make. Ill list the details below. (I know, I should've went F1A94 lol)

• 417 lsx - 3.9 stroke and 4.125 bore
  • cam specs - 240/256 .621/.604 117lsa, 112 icl (this was the suggested cam by cam motion)
  • fast 102/102
  • Frankenstein m311 heads
  • 2" kooks headers to speed engineering true duals
• D1X spinning roughly 65k rpm
  • FMIC 1200hp intercooler

Its a stick car (lvl 7 magnum f from rpm transmissions, monster triple disc, S60 rear) and the engine made about 630/590 on the engine dyno. This post is more out of curiosity and conversation. Let me know if there is anything else I can add so we can make the best informed guesses! Should be fun when its all done!

Looks like a stout build. What’s the compression ratio? Pump gas or E85?

Thanks man! 11:1 and will run on E85.

This should give ya an idea on potential, but you are starting out with a bit stronger foundation: https://ls1tech.com/forums/forced-in...etoxx-d1x.html

That modern generation blower is legit.

I made 900 WHP on a 416 spinning the D1x at ~62k through cathedral heads, stock intake and a small cam (228-ish) on pump gas. So, I'm guessing in the 930 to 980 range around 20 psi of boost.

Those M311 heads are gonna move some serious air over the factory cathedral ports for sure.
We'll need video and dyno sheets to be sure.

Thanks guys! Hoping to hit that 900rwhp mark

D1X @ 65k
11:1 compression
E85
Manual trans

I would bet right around ~950 rwhp SAE on a 2WD Dynojet dyno without any tricks, any other dyno type and the numbers can vary wildly.
