Just got these back

With the kleemann cams these heads will flow 340cfm, shooting for 600 at the wheels on the jet

 

I can't wait to see what kind of power , these ported heads give you, What pulley size do u have and what shop did the porting & polishing ,, Badm Good Job

 

Running a 185mm pulley other mods are air box, intakes, 82mm throttle body cams LT headers 3" x-pipe and catback.


At my cam lift (say .450 range), these heads outflow the best modern AFR CNC heads made for Vette`s. Another nice thing, is that boost will drop a tad (less heat and more efficient) but power will go up..

what kind of power is the car making now, with new ported heads and what is the cost of head porting?

 

The car made 508 to the wheels on a Dyno dynamics dyno using a 180mm pulley. The new heads have not been installed yet, cost of the heads is right around $3000.

 

When u get it together send out your dyno #'s , I'm considering the same modds ported heads , u can't fine any real data on power .. Thanks
Your in the fore front of modds , I can't believe no one else has done this and achieve big power & torque increases ,, Badm

 

I will post everything in this thread once its done the. One thing ive noticed about the MB community is that its great at making claims and poor and showing proof.

 

I totally agreed with u the only proof of a performance mod are dyno's and ET slips ,,, Thanks, It seems like it's the typical performance parts industry tricks selling parts that really don't make much difference except in Your wallet. As we know theirs a lot of lying and cheating , I'm like u I want to see real power without Nos ,, the motor alone ..

 

90% of the owners have no clue what they are doing and feel butt dyno numbers are useful. the other half are vendors that play off the communities ignorance. Thank god for the Jerry and the guys at Eurocharged!!!

 

Your so right there's only a couple vendors u can trust ,, Eurocharge , TT m Motorsports Bruce , Kleemann ,Eurosport , MHP, OE Tuning, Renntech , Brabus, Carlsson.. I didn't go with Eurocharge but I've had many conversations with jeremy he knows his stuff . The 55 engine is a bench mark performance motor and vendors and us modders have to keep new performance up grades coming that work ,

 

Very true i have done business with the majority of the vendors you named. Jerry and eurocharged built my car from bone stock to where it is now.
