Robsrt is back on the dyno today with our 419 stroker. First they dialed in the NA tune.
NA: 559rwhp/504rwtq
N2O Pull 1: 813rwhp/915rwtq (Only 5 degrees of timing)
N2O Pull 2:
N20 Pull 3:
N2O Pull 4:
N20 Pull 5:

I will update this as I get results

niiiiiiiiiiiiice

Correction, it was actually 559rwhp/504rwtq on the all motor pull. This is now a new NA record previously held by one of our other customers at 558rwhp. For comparison sake, this same owner (Robsrt), was on this dyno with his heads/cam 6.1 and made 425rwhp so this is definitely not a "loose" dyno.

Amazing results. What is the goal?

 

[PWR_Andy]

goal is 9's in the 1/4 without melting parts

 

[DCX Depot-Tim C]

Nice numbers! I saw that it has Mondello heads on it. Are you selling that brand now also?

[PWR_Andy]

Nah, he already had those when he bought the motor/cam from me.

 

[PWR_Andy]

just found out this was a Mustang dyno. A competitors 426 made 488rwhp on this dyno and runs low 11's at the track.

Andy, is rob running cometic gaskets? ARP head bolts or A1 technology upgrade? Curious to see what will hold a 400 shot. Also what is the cylinder pressure from a 400 shot VS Hemi~C 19psi and a 200 shot? Thanks Andy:thumbsup:

 

[PWR_Andy]

Stock gaskets with Arp studs. Im going to assume boost is harder on gaskets and bolts than nitrous but that is only a guess.

That spray pull is just sick.

[email protected] with 1.47 60ft time was best tonight. He had some obstacles to deal with but I will let him explain.

 

[FlyByU]

Damn good debut for sure, congrats to all involved.

 

[PWR_Andy]

The debut was a few weeks back with the [email protected] but he has since added the 9" and the dyno tune. Still a good night out if you ask me.

 

[FlyByU]

Ah, I guess I missed that.
