Any point in custom cam?
Any point in custom cam? Fox mustang
I have a alum 5.3. (Lh6).
799 heads
1218 pac springs
Ebay head studs
LS6 intake
S472 1.1 AR 83mm T6
Ls7 cam
Car made 672 rwhp and 735 rwtq on 18.5 psi. Traps 141mph on 17/18" wheels
I have a TH400 and a PTC converter. I cant footbrake the car much over 2500rpm and cant build any boost like that.
What can I gain going custom? I doubt it will make much more power. Wll i be able to build boost on the footbrake?
Heres the dyno graph. I let off at 5500rpm but it will still climbing

Hard to say right? I've been 145+ @ 15psi with alum 5.3 and 799 heads, 3400lb Nova. I ported the heads. Edelbrock ProFlo, custom cam by Tic.
Never been on the dyno.
I guess you don't know unless you try it.

Some people gain over 100rwhp from a cam swap. I would go with a cam from lil john. On his faceboook page they just had a car pick 116rwhp.

The pk hp numbers might not change a bunch but the low end tq could come way up without hurting the HP with the right cam. Makes it easier to build boost on the footbrake.
ill say this without trying to step on the toes of my cam selling buddies;
you don't see too many cam swaps that increase engine power at 2500 rpm vs. stock.
you need a trans brake, looser converter, or both to get the turbo happy on those cubes.

I'm with the Mouse on this one....
Even with my cams... you have to be 3200+ to see any differences...
Just not enough air moving at those RPM's to get the shaft speed up... I bet itd be a different story all together with just 700 more RPM....
And if you do decide to do a custom cam... consider a better spring please.

i just dont know if my cam isnt specd to the turbo/vic jr if will even make a huge negative difference?
The converter is the $500ish one.
This weekend i will take it out and see exactly what rpm it hits. I said 2500 but i might be off a bit just cause there is alot going on when sitting at the line. The main point is i cant build any boost and my 60' are ****
Thanks

Go to ignition parameters and enable rev limiter 1. Then go to the inputs/outputs and select the input type= ground or 12 volts. Go to your pin map and drag the rev limiter 1 to one of your 4 available inputs and wire it in the car. Make sense?
Do you cut fuel or spark or both?
I tied the 12 volt into to brake pedal so when I'm footbraking its activated and dissengaged when the pedal is released. I will also incorporate a switch so I can hit the burnout box w/o the limiter engaging.

Im with John and mouse on the RPM. More converter would wake it up, but a tq cam like the triple 12 has been known to help out a tight converter footbrake setup like that considerably. The tune, and way the piping is set up can drastically effect things as well.
