ccsl7578 Posted June 20, 2012 Report Share Posted June 20, 2012 I know awhile back there was a lot of discussion about going the N/A route verses the supercharger route. For those of you that stayed N/A and added heads, cams, headers, intake, throttle body etc are you still happy you went that way? How much HP did you gain with these mods? Just wondered. Thanks!

CHEVY2SHELBY Posted June 21, 2012 Report Share Posted June 21, 2012 no cnc heads, cams, tb, cai elbow, intake manifold, coil plugs, UD pulleys, headers, tune 124 rwhp Link to comment Share on other sites More sharing options...

ARMORINE Posted June 21, 2012 Report Share Posted June 21, 2012 cams, full exhaust, UDP, CMDP, throttle body. 330 at the tire on a dyno dynamics. havent gotten it on a dyno jet so i dont have any numbers that are comaprable to others. i've very happy with her, so happy in fact that im about to start building an NA max effort stroker if the parts come through if not itll be a normal 4.8 forged set up spinning to 7800 on meth Link to comment Share on other sites More sharing options...
TheKurgan Posted June 21, 2012 Report Share Posted June 21, 2012 Here's my quest for power - I got to 335 NA. It wasn't enough so I added a 100 shot of nitrous. That really picked it up but still not enough so I went to a 125 shot. That got me to about 450 to the rear wheels....still not enough. Now I have the Paxton SC and can finally say I am content...for now. Link to comment Share on other sites More sharing options...

ARMORINE Posted June 22, 2012 Report Share Posted June 22, 2012 im betting your right. my buddys 2.6 kb whipple SGT only pulls me by a door length from 1st-3rd. im very happy with her. she definitly turns heads with how she sounds. i'm gonna try and get her on a dynojet some time. any onw here had their car on a dyno dynamics other then me? went and placed a down payment on an eagle stroker kit. picking up the kit next week. need to find some high compression pistons for it. 10.8 is my minimum compression target.

ccsl7578 Posted June 22, 2012 Author Report Share Posted June 22, 2012 I know I thought I had to have a supercharger and 500+ HP, I guess because the GT500 had that much and I wanted to keep up with them...? I would like to have a little more HP but don't know if I need that much, especially after reading the thresds about problems getting 500 HP to hook up. Also for autocrossing/road racing I think you would want the power to come on more smoothly/gradually than the sudden power boost you get from a supercharger. Would like to hear from guys autocrossing/road racing with an SC car. THANKS! Link to comment Share on other sites More sharing options...

ccsl7578 Posted June 23, 2012 Author Report Share Posted June 23, 2012 Looks like this kit from Ford Racing will give an easy 100 HP and put us up with the new Camaros and 5.0 Mustangs. This is kit # M-FR4-S197 ($4,099.99), from the web site: Ford Racing Parts Direct. In the dyno results... the car tested also had long tube headers installed. "Ford Racing has worked hard to bring together a complete top end power package. Through extensive testing and prototyping, Ford Racing has designed a matched set of CNC ported heads, Hot Rod Camshafts, billet throttle body, and their new Ford Racing intake manifold. The hot rod cammer crate engine currently offered utilizes the stock OE manifold and throttle body and is rated at 350HP. That is pretty respectable for a standard 4.6L with the stock heads and hot rod cams and cold air intake. But now, with the addition of the new billet throttle body, high flow manifold, and CNC ported heads to the hot rod cams; the power jump for the 4.6L 3 Valve engine is incredible. All of this is accomplished while minimizing low end torque losses. So you retain the low end response off the line and gain huge power in the mid range and top end. The Ford Racing 3-valve intake was designed using CAD modeling technology and data from the production intake manifold ensuring it's matched to the volumetric efficiency and unique characteristics of the 3-valve Modular engine. From the CAD model, nylon rapid prototype manufacturing was used to build numerous manifolds with varied volumes and runner lengths which were dyno-tested for power confirmation before final design sign-off. Top End Package Includes Dyno Testing Update April 2010: Ford Racing has tested a 4.6L motor with this top end power package, their 85MM cold air intake, and long tube headers. The result was an EASY 425 HP at 6300 RPM and 380 Ft-lbs Torque at 4600 RPM with proper calibration. Proper custom calibration is important. Power continued to build to over 440 HP as the engine reached 7000 RPM. The engine also made over 275 Ft-lbs Torque from 2400 RPM and steadily increased to 375 Ft-lbs Torque at 4,600-6,000 RPM. These numbers are SAE corrected number as measured on an engine dyno at the flywheel. Expect to see about 12-15% less at the rear wheels with proper calibration on a manual transmission. This power package is a nice alternative/update to keep your car on pace with the new 5.0L motor while staying normally aspirated with great low end torque and throttle response."

07SGT Posted June 23, 2012 Report Share Posted June 23, 2012 Was this the test where the stock motor started with very high numbers? And I would not recommend taking our stock motors to 7,000 rpm. The SC is still the best bang for the buck as long as you keep the boost moderate(7-8 psi). Link to comment Share on other sites More sharing options...

Also for autocrossing/road racing I think you would want the power to come on more smoothly/gradually than the sudden power boost you get from a supercharger. Would like to hear from guys autocrossing/road racing with an SC car. THANKS! I can speak to racing it NA. Autocross: keep it NA. SC really doesn't help in short acceleration spurts and if you want to compete for real (SCCA, etc.), they will class you in places where you will not be competitive. Track: depends. If it is for competition, which I doubt since there are better/used mustangs out there for that, your racing options are limited with SC. For track days, I would take it out as is with better brakes/tires first before using that as a criteria for making a decision. It really depends just how hard you are willing to push the car against others. For example, at Summit Point this year, I passed dozens of GT500's that either did not want to risk their car at all or whose suspension was not up to snuff. The fastest cars out there were SC'ed. But if you want to compare your track times to American Iron (i.e. Pros), then keep it NA. For the above reasons, I am keeping it NA. Just to put perspective on it all, the Cammer 5.0 in the FR500C ran about 420hp NA in a 3200 lb car for the 2005 season and won it all. Point being, you can fun with just about any HP # with the right car setup and driver. That was driven home to me quite clearly by my Instructor in his race Miata who lapped two Corvettes (also Instructor run) twice during his session that I rode along. -Tom Link to comment Share on other sites More sharing options...
ccsl7578 Posted June 25, 2012 Author Report Share Posted June 25, 2012 Thanks for the info Tom! I did the brake upgrade, now I need wider tires/wheels before I even think about adding more HP. Mark Link to comment Share on other sites More sharing options...
