Dyno'd truck at school today for free!

[Intense RT]

Engine mods:

-Ported barrel intake
-Ported exhaust manifolds
-JBA head pipes (99 RT) run into true duals, H pipe at trans X memeber and Dynomax X muffler dumped at axle
-HS non-adjustable 1.7 rockers
-double roller timing chain with tensioner
-brass cap and rotor/MSD plug wires/NGK zfr7f-11 plugs gapped to .047/stock coil
-bosch 4 hole injectors
-slotted Crank Position Sensor
-ported true 50mm stock TB with 14" round 2" tall,extreme lid K&N filter
-March underdrive crank pulley
-Black magic Xtreme 3300cfm fan

Dyno'd at 256hp and 333 torque at peaks. Don't have sheets with me yet (out in the truck). These are corrected figures on a Dynojet. Still need a tune.

what'd it show for max rpm? 5900?

Hey hows that fan working out for ya?

That's pretty damn good for those budget mods. Nice work!

you have ported exhaust manifolds AND JBA headers??? i'm confused. you also have an H-Pipe as well as an X-Pipe within the muffler?

I think he meant he has the JBA tubes comming from the exhaust manifolds. Then modified to true dual. Then goes into a H pipe at the Trans Crossmember.

And he probally has a Dual I/O muffler, the ones where the pipe cross each other in the muffler.

I've got the magnaflow that has the x-design. Kinda convenient and saves space, weight, and money. Those are some pretty good numbers for your mods. Not a whole lot into it, but good figures coming out. Nice job

NO, I have ported stock exhaust manifolds and JBA head pipes, or some call them down pipes. I have 2.5" exhaust from the end of the 2" JBA pipes, that opens to an H, goes about 4' then there is a Dynomax X series Muffler to scavenge the slowed down gases from the 4' section of dual exhaust. I did this stuff after doing some extensive zero backpressure exhaust research.

Hey hows that fan working out for ya?Works flawlessly.

[Intense RT]

Thanks, I figured the truck did well, just wanted to run it by you all to see HOW good I did. An M1 and a flash would be nice about now, along with an IN LINE electric water pump. 300rwhp??

the m1 is good for about 50 hp/50 tq. im puttin mine on tommorow hopefully. ill let you know.:woot:

The stage you're at now.. the electric pump conversion would hardly be worth the trouble.
I bought a high output alternator to compensate for the increased electrical load (fuel pump, water pump, nitrous solenoids, etc)

You'd see more dividends from weight reduction.

It's not worth a 50 peak-peak gain, its worth 50 hp past the peak where the beer barrel really falls off. I'd say you'll see 30 more peak hp with the m1

[Rtspeeddemon]

Nice numbers for the mods for sure!

[Five9Dak]

I don't think you're going to pick up 44hp from an m1 and tune, you're afr is prolly allready close given you make a good bit of power for the mods you have, and you allready have timming advance from the slotted crank trigger. I think a more realistic expectation is 275-280hp on that dyno, which would still be stellar compared to most trucks. I hope you can prove me wrong, but very few trucks even approach 300rwhp with stock heads and cam.

[Intense RT]

It would be nice to have some lighter wheels, probably a couple hp there.
