How to build an 11 second NA NPI on a budget

by Brandon Rovendro

 
 
I bought the car in October of 2006 when I was 15 years old.  It had nothing more then a cold air intake, 373 gears, under drive pulleys, and a few appearance mods.  I daily drove it that way for about two years until I finished high school, stated working full time and was able to buy a daily driver. 
 
I started the motor build in June of 2008, and for 6 months I pieced together a whole engine including a block, crank, rods, pistons. etc.  In the 6 months I collected parts I hand ported a set of NPI heads myself.  Then I had a 3 angle valve job done, stainless steel valves, and comp beehive valve springs were installed.  The bottom end consists of a stock iron block, that just needed a good hone job, and the crank got a good polishing too.  It has a set of Mod Max forged I beam rods, and 96-98 4v cobra pistons, using perfect circle piston rings.  Using the 4v pistons bumped the compression ratio up to a little over 10:1.  It has Clevite bearings, and a FRPP high volume oil pump,  Modular Head Shop stage 3.5 NPI grind cams, MHS cam degree service, and TFS adjustable crank sprockets. 
 
The intake setup on the car includes a JLT ram air intake, 90mm mass air flow, a 75mm throttle body which is bolted to the MHS 6061 upper plenum.  It has a 2" open phenolic carb spacer and the Edelbrock victor JR. for the 4.6L.  That also received a full port and port matching job by myself. 
 
For the fuel system the car has a Walbro 255lph in tank pump, Edelbrock fuel rails, FRPP 30lb injectors, and the fuel pressure is regulated by a MMR fuel pressure regulator.
 
For exhaust i went with Flowtech longtubes, O/R H pipe, and MAC flow path mufflers with turn downs.
 
The car still uses the stock T45 transmission, and the rear has a set of ford racing 4:56 gears.
 
The car has a full UPR suspension.  The front consists of, UPR K member, A arms, and 14150 coil overs, Maximum Motorsports caster/camber plates, a Steeda bump steer kit, and a 99+ mustang dual piston brake caliper swap which also cut a few pounds.  The rear has a set of lowering springs, UPR solid upper and lower control arms, with spherical bushings, and Lakewood 50/50 shocks.  There are no sway bars front or rear.
 
It rolls on a set of Race Star Industries, Dragstar rims.  15x3.75 in the front with 165/80 tires, and the rears are 15x8 with 275/50 Goodyear eagle drag radials.
 
The car has some weight reduction done to it and weighs just under 3000lbs empty.  It has no air conditioning parts under the hood, manual brakes, and no power steering.  It still has a FULL leather interior including the OEM mach 460 sound system!
 
The car gets its look from a cobra front bumper, smoked headlights, and fog lights, a Kaenen 6" cowl hood, and a saleen s-281 spoiler.
 
In the next few things I plan to finish the rear end build, a 99+ Coil on plug swap, a set of 90/10 lake wood front struts, and an aluminum drive shaft. The car has been a very fun project, and is no where near being complete. The car has been a best of 11.93@115 in the 1/4, with a best 60' of 1.59! and it didn't come easy. The car will also be getting a nitrous kit in the next few month, I'm hoping to get it into the 10.90's on a 125shot.
 
MHS Stage 3.5 NA NPI cams set the NPI NA record at 12.08@114MPH
 
MHS Stage 3.5 NA NPI cams become the first to break the 11 second NPI NA barrier!
