A proper tune and the LTs should get you your desired numbers.

 

Headed back to the dyno on 9 Jan - will post results.

 

In for results

 

It's the 18th, what happened?

 

Sorry about that...been out for a few.

Got it to 383 / 415 for now with no add ons. Will be saving the scratch for a TVS1900 or 2300 to get me close to 500. Still, I enjoy the way it drives and reacts so I'm happy with it.

 

Man that torque curve drops like a brick...

 

what is the exact combo? it's hard to believe that a stroker hasn't cracked 400 yet. my stock bottom 6.0 was at 449 RWHP IIRC.

 

I believe the 72cc dish in the AFRs is what's keeping it under 400 right now. I went with them on purpose with the intent of going FI in the future. It was a current sacrifice for future gain. Went for a good ride this morning on the way in all the same - wheels broke loose hard @ 50mph when I passed a slow mover...nearly snaked underneath the damn thing before I let up.

Pulled out the sheet again to double check - was 383 / 402...

 

Sorry but I'm a newb at this stuff...What does this mean? Thnx.

 

The rpm axis is cutoff in the first pic, but just looking at the curve I would guess torque peaks around 3400rpm than just falls fast after that which is why the power is low. Good setup for towing or seat of the pants feel, but not so good for high horsepower. If you could move the torque pand to peak around 4000 you will make another 50hp. Torque falling like that could mean restrictive exhaust, intake, or valve spring issues, or just a function of the cam in there.
