How much pulse to be around 650hp?

[monster50iii]

I ordered a 10mm pump today. With my stock cp3 I made 580hp at danville with stock sticks and his 3794. I have this same cp3 maxed out with the new 60% lbz tipped injectors from DDP. im holding 185-190mpa at 2100us right now. Just seeing what everyone's thoughts are to reach 650hp? Thats all I want, I don't need an catastrophic failures lol

With stock injectors and a danville 3794 my lbz put down exactly 580 on a 2400us tune. Pistons lasted about 30,000 miles, If I remember correctly It's 2100 or 2200us with these new 45% Injectors and it makes between 650-700.

I know at 2100us I'm maybe around 600hp.. it feels a bit more than the stock injectors but not much. I suppose the new sticks don't return as much fuel.

What's your rail pressure holding in psi?

Last I checked which was a while ago, 27,×××.

2400 pulse should get you close. You’re already in the danger zone tho

 

[monster50iii]

I'm hoping with the 60% lbz (or 80% lmm) Stix, things stay happy near 650. Ill probably start at 2250 or so and see how things feel. I'll keep timing very conservative

 

[OleBlackyLBZ]

You on stock motor?

It all will depend on the turbo you are using. On a 50 over S466 I made 742 at 2200 usec. Stock engine lb7.

Yes stock engine, I've got an s364.5sxe.

Just detorque the tune. I’m probably stupid but I fear 1200tq at 2800rpm not 600hp+ at 3200rpms+.

This. Torque is the killer, not overall HP. Torque = cylinder pressure and cylinder pressure bends rods.

Torque shouldn't be a problem for him, those pistons on the other hand

Duh, for some reason I thought it was 01-05. Probably should’ve figured it out when he said LBZ tipped injectors. Horse a piece, piston failure or custom short rods both suck.

I’d still drive it with bent rods

You guys act like I'm shooting 700+ hp lol. There's guys making 620-660 on stock sticks. These 60's should really help save things. A 2250us tune with a max of 18* or so at 195mpa or so shouldn't be too destructive hopefully.

It’s still cylinder pressure. Weather it saves the rods or the pistons it’s a win. I ain’t cracked a piston at 1100tq, so I’ll shoot for 700hp and 1000tq. My truck ain’t my daily though so if I break something I have time to fix it. Hopefully it don’t come to that any time soon. Maybe I’ll make it to 1000hp....for one pass....lol

Man what happened to the old days, I remember running a 3250 pulse with stock sticks

 

[monster50iii]

I may have to get it on a dyno for a day and get it where I want it. Jags Pro Truck shop might be an option.

It has arrived!
