I think it said sae std. I’ll check when I get home. Didn’t realize I must have cropped it out. What are your thoughts on the numbers? Or did you just come in to make sure the dyno #s weren’t inflated lmao

Here’s another dyno sheet before the retune which is also std sae. Tune needed a bit of tweaking. Same exact mods.

The before and after on this graph is I/h/e vs. h/c/I and mods listed above.

Nice. I love seeing all motor cars putting down power. Something to be said about all motor vs slapping on a prochargwr.

Thanks. I give all credit to Tony Mamo at mamo motorsports for hooking me up with the parts combo. His heads are killer and put down great power with a drivable 229/233 cam.

Also pro charger might get slapped in next year after I finish the 408 bottom end and lower the compression a bit.

i mean even if you take away the 3-4% supposed difference between j607 and j1349, you're still making 460-470 wheel horse. most h/c/i 5.7 setups are like under 450.

you have a great combo there.

I laugh when people look so far into those small details. It’s all for fun and to be honest the only thing that matters is what it puts down at the track. Also I texted the tuner today and he said if anything the standard sae probably wasn’t in my favor that day.

true. small details can add up tho. and it can be fun trying to put together a good combo on your own to see what it can do.

these days people just get a junk 5.3 and slap a big chinese turbo on it, with stock heads and a cam, and make banzonkers power. i kinda feel it takes the fun out of putting together the "perfect" engine combo. can't beat what works, though.

Agreed. I’ve had a poorly put together turbo build in the past (400+ hp Honda) and if I ever have to deal with that much turbo lag again I’ll jump off a bridge lol.

I am at 437 rwhp with little 5.7 HCI throttle body MAF, 1 piece carbon fiber ds, etc. Fun setup. You are making good numbers.
