Stock eaton(no port)
AED tune
11.4 A/F
19* timing
Not sure about dyno but mustang dyno?

 

[xsboosted]

What type of dyno?

 

[gabe1530]

who tuned it? how much timing? whats the air/fuel ratio?

nice amount of torque but the hp seems way low.

 

[racebronco2]

What does your tuner say is the problem? What type of dyno? Post the dyno sheet.

 

[346CamaroSS]

Dynos are dynos man.. you still on the stock Eaton?

 

[matt87]

ya thats a combo begging for a twin screw or at least a port.

SF cali, so either AED/TPS/NexGen/or maybe RPM tune.. Dyno's are tuning tools. how does it feel?

 

[CobraBob]

Ditto on what people are saying about dynos. If you're using the stock Eaton then the power isn't off by a crazy amount. Your torque is great. Are you on a 91 octane tune? Stock lower? Stock, unported Eaton?

It's tuned by AED it's on a dynamics dyno.. The numbers are correct and probably SAE corrected.. I wouldn't worry about the numbers, Shaun knows his stuff and that is quite the motor with a none ported Eaton.

Your motor is begging for a TS on top.

 

[SVTwnaRUN]

U guys think will i see differents on a port? Or just waisting my time.

 

[TVSCobra]

Vmp tvs


Also what exhaust setup do you have?

 

[watman02]

how much boost? what are your iat2 temps?

 

[SVTwnaRUN]

We saw boost at 14psi and whent down to 10psi at 6200rpm

Exhaust is stock manifolds,BBk OR X,Magnaflow exhaust
Temps he said they where good not a problem at all their.

 

[D-MANN]

Skip the port dude. Get a TS on that ride

 

[watman02]

beign that ur loosing boost pressure ur tuner is right ur eaton cant keep up with what the engine can consume as the rpm goes up. That is why ur power is down....u need a better blower, its maxed out!!!!!!

 

[Blueline]

I agree, Boost is a measurement of restriction. The 10psi your seeing at 6200 rpm just goes to show you that motor is breathing and begging for more. You need a bigger blower now....

 

[mustang john]

You have a nice 5.0 stroker and your corking it on both ends with stock manifolds and a stock unported eaton. Get some LTs and at least a ported blower with a #4 lower pulley and watch the numbers jump 80-100rwhp.

 

[younggun04]

It's probably just the Eaton and the fact you were on a dynodynamics (which reads similar to a mustang dyno). your numbers are fine. My ported eaton did 432/420 On a mustang dyno and I put it on a dynojet and made 494/488 on a 2.76 upper only with no changes.

Only think that might be an issue is if the engine builder didn't degree the cams properly that could be a loss of power right there.
