Need a little more power?? Got all the Mods and STILL under the 200 WHP mark?? Dont want the Turbo 07 to look down at your First Gen MCS??
Got to have the low to mid power range for the Dailey Street Driving when you are not on the Boost?? With Thumper Performance Head we make the head to YOUR application!! NO low end loss... NO hesitation or flat spots..
Yet we are pulling over 211- 215 SAE WHP, actual 222+ WHP ( 240-245+BHP ) with Dailey drivers just like yours!! We even do the Head for the MC!!

Thumper Performance Heads come in THREE levels of performance.. And now we have a Head and Cam Combo!!
Check out Thumperheads and see if we can halp you..

Thanks
Thumper

 

Bump for an awesome head!

 

Are there any flow numbers?

Bill

 

Sorry Bill... the flow numbers are not given out!! Stupid?? Maybe..!! however, there are too many " shoulda, coulda .." responces when numbers are posted.. and for that reason I use Dailey Drivers with the usual Mods.. and dyno them, no TEST Mule with all the bells and whistles!! ( even Dyno numbers come under Flame..) On my site it has some basic sizes, and with that said , remember that I make the heads to your application, the MCS or the MC will use different paramiters for the Forced air or the N/A engine.. it isnt a "one head fits all. Cool?

SOOOOoooo...... have a stock inter cooler, stock cam, stock header , and just Stock Tune, CAI and pulleys?? then you can be looking at 210- 225 Wheel HP. ( 240 BHP TPR-1) !! If your moded MORE.. then the results are more,( 245-260 + BHP TPR-2 ) even a shown increase in Gas mileage !
The heads pull the mods together and allows everything to pull more power! Of course all this is known to everyone already!! The Dyno on the MC we have done is still out ( Dyno day is Jan 20th ) . However the owner of the MC is loving it!! 130 MPH and climbing!! Again, these are regular Dailey Drivers like yours and mine!! Hope this helps..

Just me...............................................
