New numbers?
5.0 Stroker NA Build
- Thread starter Doc Hawk
- Start date
I am pleased. I would not go this route if I had to pay cash. Too little bang for the buck. But for $2000 out of pocket, it's sex. I need to get more rim and tire now, because I cannot put the power down on the street. So that's a nice yardstick... definitely pops.
I would also say that the 4.10's were perfect with a stock motor, but if I were gearing for this build I probably would go 3.73. Don't get me wrong, it's stout and completely drivable, but it climbs through the gears so quickly that I probably would be happier with something a little taller or a 6th gear. Would I trade it now that I have it? Nah, it's fun.

very nice. Glad everything worked out
na svt:
The second youtube said 375rwhp in the notes below.
How does that sit with his mods, the 5.0 stroker and the 106060 cams??
The stroker was about a 40 flywheel hp gain?..34 rwhp..just guessing again.
Making these same mods on a 4.6L produce 341 RWHP??

You should bring it by Barona tomorrow.
That's about where it should be if the numbers are Dynojet/SAE factored. STD numbers are a little higher.
The 10.5:1 stroker adds about 25rwhp and the cams about 30rw. I bet the tq is much higher than a stock engine.
Pretty healthy. Congrats
Ported TBs add no power, none whatsoever.
Without headers a ported intake will add 5-10 and a short runner 15-20.

Yep
There is the whole polished intake and polished SRI talk again...there are RPM and torque considerations and trade-offs.
Then if you go PSRI and higher RPMs (7K+)..and go UDP/Damper you need to choose the right damper.
As I understand it:
More TQ down low..less HP up top
< 7K RPM: PRI and March UDP/damper set is the way to go.
Less TQ down low. more HP up top
>7k RPM: PSRI and March UDP with ATI damper is the way to go.
I'm not stating this as fact..just looking for corrections from NA SVT..again..and thanks AGAIN.
Doc Hawk:
Please keep us posted on the progress!!
And dynos Please!! When you get the chance...As I am interested in the seeing TQ curves especially...

A 10.5" short runner will not sacrifice midrange ho or tq nor will it require the engine to be taken over 7000rpm.
NA SVT:
OK excellent....
Q1: And this 10.5" PSRI is a ported 99-01 cobra...03-04 Mach1 intake we are talking about??
Q2: There is also "another" PSRI that is 6"?? for 7K RPM applications (different CAMs..106200, 300, 400 whatevers..) which is a cut down 99-01 intake.???
I've been confused about this for a while now...and hope this helps this thread... Thanks in advance...
All short runners start life as a C head intake, Mach or Cobra.
5-6" intakes make power to 8500rpm
10-10.5" versions make power to 7000.
thank you!!!!!!!!!!!!
I would look into the exhaust before doing a PSR if it's the cork adding more air in front is not going to help much. You might look into a set of JBA shorty's I know people say they are not worth it but it might be your only option. If I remember right they are carb exempt as well. I owned a set and while I never had them on my car I know they have to be a improvement over the restrictive stock manifolds. These headers will not help with a scavenging effect but rather dissolution as all of your exhaust will not be concentrated into one tiny pipe all at once. Here is a link to a well respected NMRA factory stock racer that ran them and what he had to say.
Kooks vs JBA Dyno Results - Surprising.... - Ford Mustang Forums : Corral.net Mustang Forum
As far as PSR's go a well built PSR can actually make more TQ over a stock intake with little too zero loss in the entire RPM band. The PSR on my car was a mild one while still making great HP numbers and a solid gain in TQ across the RPM band. I am running the same Comp cams and with this intake my car pulls like a MOFO to 7,000 rpm's. I think with a set of headers and a PSR you should easily break the 400rwhp mark.

Bob's combo had only 289ci and stock cams and the LTs he tested had only 1 5/8" primaries. A cammed stroker has evacuate a lot more exhaust therefore it requires at 1 3/4" primary tubes. The power gained by adding LTs of this size will be far greater than what Bob experienced.
Bob's combo would have picked up more power with the 1 3/4" primaries also.
True but Bob also did not live in California where you have to pass multiple inspections. I am just giving this guy some legal options in no way did I say this was ideal for his combination!
