Well I had my car tuned and dyno'd yesterday the new cam put down 391RWHP@6350 and 371RWTQ@5000. The numbers are corrected and it was on a mustang dyno. The cam carried peak power from 5950-6800 so Im very happy with the power curve.

Im just wondering how good these numbers are for my cars mods. The mods are in my signature.

 

good numbers for a mustang dyno!! Can you post the graph?

 

Ya ill try and post it tonight

 

here they are

 

Really stout power at all rpm levels. Bet it pulls hard. I'm glad you are pleased. You should get some really good ETs at the track with that kind of power under the curve.

 

Thats what I was hoping to hear Pat Im used to seeing alot more dynojet numbers on here so I wasn't sure what I should expect from a mustang dyno. My tuner seemed to be very impressed with it considering I have 4.10 gears 17x11 chrome rims and no under drive pulley. The cam lopes hard and idles great @ 900rpm and just like you said it would it peaks right around 6300-6400. The first thing I we both noticed was how long it carried peak power which surprised me considering its 111+4.
Thanks pat im very happy with the cam and it was well worth the the 25bucks you charged to spec it.

Pat I was wondering though the first dyno run the a/f was 11-1 and it put down 390rwhp on the 4th pull it was a close to perfect at 12.8-1 and it put down 391. I would have thought leaning it out from 11 to 12.8 would have gained some power but it didn't could there be something holding back my peak numbers a little bit or is that normal.

 

Nice numbers. I'm going to be ordering a 230/234 110 LSA cam to go with my AFR 205 heads, so I'm glad to see some numbers with this cam. If you get a chance, post up an idle video of the car.

 

I will its got a mean idle even at 900rpms.

 

Thumbs up for Patrick and the EPS cams. Nice power!

 

By the 4th pull, your motor may have been more heat soaked than it was on the first pull. This may be why you didn't gain as much as normal. Of course, the gains will be more if you went from 11.0:1 to 12.8:1 than if you went from 11.9:1 to 12.8:1. There's very little power difference in the 12.2-13.2:1 A/F window. A few tenths above or below won't show a big difference.

 

good numbers for a mustang dyno... that would be roughly 420-430whp on a dynojet!! The only thing that seems odd is, I have seen other eps grinds in the 226/230 range put down the same numbers.

 

Good numbers , I like the curve .

Well done Pat G .

 

Well he waited before the last pull to let it to cool down so I don't think thats it.
The first pull was 11-1 afr for sure so I firgured it would pick up some power but it didn't. My tuner said the clutch looked like the clutch might have had a Very Small amount of slip around at 4800 so maybe that's whats causing it.
He said it was very little though so Im not sure.

 

Great numbers!

Pat G, I was wondering what differences would be realized if this cam was ground on 113+3 or 114+2 keeping everything else the same?

Thanks

 

The OP's cam was ground with a 107 intake centerline (111 LSA +4). A 113 LSA +3 cam would be 110 ICL and the 114 +2 cam would be 112 ICL. By retarding the intake centerline, you are decreasing dynamic compression which will reduce low and mid-range torque and increase the rpm at which peak power occurs. Whether that's a good thing depends on your combo. This 230/234 111LSA +4 cam was ideal for the combo of mtuggle.

 

Okay thanks for that explanation, makes sense Last question, what is the most dynamic compression you can get away with on 93 pump gas?

 

From what I've seen here, been told, and witnessed first hand Mustang dynos are typically 8-10% lower than a Dynojet. That said, your numbers look pretty good! Send those heads off to a good porter and time some bigger numbers!

 

I cant wait to hear a idle clip. That cam is along the lines of what I am thinking for my car this winter.

Heres an idle clip its idling around 900rpm

 

Nice!!!
