Bullfrog Throttle Bodies are bored to micro tolerances, and a new purple anodized butterfly is machines and hand fitted to provide the best idle possible.  The velocity stack is tapered to induce high velocity air flow into the intake manifold resulting in super throttle response, increased midrange, and big top end. Bullfrog Camshafts are designed and engineered by Gude Performance and pack the punch to do the job!!!  One of the most effective ways to increase the performance of any four stroke engine is to optimize the valve lift and timing of the camshaft. Bullfrog Camshafts are designed for the performance enthusiast who wants explosive top end power, or monstrous torque through the midrange. Gude Performance has developed the most effective camshafts for drag race, road race, and circle track cars.   Every Bullfrog Camshaft is constructed from a factory core, tested, and proven to the highest racing standards. Bullfrog Camshafts by Gude Performance are the measuring stick by which all other camshafts are measured. (Not a low price, poor performance look alike).

Bullfrog Computer Chips are matched to the specific Bullfrog Camshaft.  Each ECU fine tunes ignition timing, fuel curve, and rev limiter, to provide the optimum performance available. Bullfrog Headers are fine tuned and match ported to the high flowing  Bullfrog ported and polished cylinder head.  This unique 4 into 1 design allow for excellent torque in the midrange and monstrous top end seat slamming  pull!!!

Gude Performance definitely brings "more performance for your dollar" with the Bullfrog Race Packages!  Now available for Ford's new ZX2 and ZX3!  Each race package consists of a ported and polished, high compression cylinder head, with  racing valve grind,  ported intake manifold, high velocity throttle body, camshafts and for some models matched ecu of your choice.  Each Bullfrog Race Package is the "for sure" choice for any serious performance enthusiast!

BIG BORE-THROTTLE BODIE- PORTED INTAKE MANIFOLD- PORT                      POLISHED HEAD AND CAMSHAFTS

1. Intake ports are ported to create maximum velocity then rough cross hatched to provide better fuel atomization, which increases combustion efficiency providing increased power both at low and high rpm.

2. Exhaust ports are ported to drop internal pressure quickly, yet provide enough velocity to scavenge well, insuring a full fresh fuel and air charge will be delivered to the combustion chambers, not diluted down with left over spent gases from the last firing.

3. Head surface is milled them hand lapped to create a multi directional #32 micro Finish surface, this leaving hundreds of micro ridges to be crushed down by the steel gasket forming a super micro barrier for better gasket sealing.

4. Intake to head ports are purposely mismatched or stepped to fight unwanted reverberation when flowing  near supersonic speeds and helps to reduce boundary layer effects improving port flow.

5. Valve seats we have tried 3 angles so called 5 angle, and many other valve and seat combinations, we have found that the factory angle on the valve is overall the best and that the blended radius parabolic valve seats pioneered by Gude performance provides the most horse power and longevity on most Imports.

6. Valve guides in most cases we have found that shorting the valve guide is helpful and will promote increased flow while still maintaining excellent valve control.

7. Valve springs all Gude performance camshafts are designed to operate to extreme rpm on stock valve springs, we spent countless hours designing and developing profiles which will not require a high pressure valve spring which can cause added friction and valve stem failure due to the high loading of stiffer springs  A few exceptions we will require a spring change to control the valve float or spring bind..

8. Camshafts Gude performance Bullfrog or Stinger cams are included with all Gude head packages, all cams are ground to precise tolerances, and are of the famous Gude profiles. Gude poured out all 30 plus years of experience, into designing cam profiles that are stable at extreme high rpm with stock or light valve spring loading, this increasing horse power and engine reliability, as high valve spring loads can cause excessive wear and result in total valve stem failure destroying a expensive engine.
