Testing is done on our High Flow '96+ Vortec Throttle Blades and our '96+ Vortec Ported Throttle Body!

 Test vehicle was a '97 Vortec 5.7L K3500 Crew Cab (4x4, 8ft bed, single rear wheels)

      We chose this heavy vehicle so that we could prove how well these parts work. Remember, when comparing two vehicles with the same power the lighter vehicle will always respond more favorably to hp/torque  increases than the larger and heavier vehicle. Therefore, the lighter your vehicle is the quicker it will be with the same modifications.

This vehicle is 100% stock and was tested with the below parts only. This vehicle has 101,000 miles and weighed in at a portly 6860lbs!!! For reporting consistency we made 15 runs on the same day and then averaged the results.

Distance	Stock Throttle Body	Stock T-Body with our CFM-Tech High Flow Blade	CFM-Tech Ported Throttle Body
60'	2.8700	2.8162	2.6722
330'	7.8422	7.7444	7.5036
1/8 mile	11.8718	11.7672	11.4602

Driver's response - " The acceleration test #'s are impressive but they don't show the even more impressive difference in throttle response, acceleration, and sustained mph at lower throttle angles. The throttle response is amazing!. Just a little throttle and this truck gets up and go's now whereas you  used to have to give it a whole lot more throttle . This (truck) used to be a lackluster  performer with it being so heavy and having a 5.7 instead of a better matched 7.4L.. The difference with the High Flow Throttle Blade was much better than stock. When the Ported Throttle Body was bolted on the difference was even greater. I hope the Ported Throttle Body stays on this truck."

'96+ 4.3 V6 / 5.0 / 5.7L Ported Throttle Bodies are available!!!

Thank you for the PVTB-430, I can definitely feel the power - Ray C.

I put the PVTB-500 in my '99 Suburban and the power is unbelievable. Thanks a lot. - Shawn M.

CFM-Tech's  '96+ Vortec 4.3 /5.0 / 5.7

High Flow GM Throttle Blades

  Do you want more power with less throttle?
Do you want more power with more throttle?
Do you want more power for less money? Say under $50?
 

The stock throttle blade is on the left.  Notice how much area the restrictor takes up at full throttle! At less throttle angles this restrictor closes off even more air and, yet worse, at low throttle it totally closes off one side of the throttle body opening.

            Our High Flow Throttle Blade for the '96+ Vortec 4.3 / 5.0 /5.7L engines is shown on the right.               What a difference! Much more air off idle and way more air at WOT!!!

Your stock engine will like the extra power. Your modified naturally aspirated, nitroused , and/or supercharged 4.3, 5.0, or 5.7 96+ Vortec engine will love it! Forget you even heard about throttle body  spacers for these engines, this is the real deal! Airflow, Airflow, Airflow!

     This low cost modification can easily be performed by anyone in as little as 10-15 minutes.  These are not modified factory throttle blades! They are all new! No cutting, no welding or soldering, and no re-drilling involved!

     Our  replacement High Flow GM Throttle Blades for the '96+ Vortec 4.3 / 5.0/ 5.7L engines have been a smashing success. It is unbelievable how word spreads so quickly when a low cost product works so well!. We'd like to thank all the forums - especially  s-series.org ,  s-seriesforum.com , s10planet.com , mys10.com , and  fullsizechevy.com  for your gracious comments and performance reports pertaining to our GM Vortec High Flow Throttle Blades.

" Very noticeable, thanks for the great product....Marty 'One very satisfied customer' " - 4.3L 2000 Sonoma

     Take one more look - Notice in the picture above that  the stock throttle blade has a large airflow restricting piece that is riveted  to it.  This "restrictor" was designed  to close off one side of the throttle bore during low throttle input.  This way, when low throttle input was used, low power output is produced. Past approx 1/4 throttle angle the deflector side of the throttle body will start allowing air thru. As the throttle is applied farther past this point- ie: the driver is wanting more engine power - more air is able to get in. This arrangement works well for an average driver, but not for the Performance Enthusiast who says ...." I want power now and I want power at all speeds!!! "

Just so you know,

•  We have tested our new replacement High Flow 4.3/5.0/5.7L Throttle Blades for over 70,000 miles with no adverse effects. Emissions does not change, check engine lights do not mysteriously illuminate, and mpg does not suffer. 100's X 100's of customers from all around the USA have been using these since February of 2002 and have reported only very positive results!
• Many customers report gains of .1 - .2 seconds in the quarter mile. We've had quite a few customers report better gains than this but since their results are not typical we will not print  them.

Never before has their been a product for under $50 (and under $100 for that matter) that makes this much horsepower!!!
