14mm head

[turboram]

I purchased my first 14mm head this week and will be installing it on our pulling truck.what hp have you all experienced with a 2.6 charger ,port,and cam? I haven't found to many similar setups in the dyno section

[oldestof11]

You are pretty much on your own. Look for around 400 to 700.

[skilletky]

dont go too crazy with the rpm's. ive read that they dont like high rpm's. have you dynoed the engine how it is with a 12mm pump?

[RCCUMMINS89]

what injectors you runnin?

[turboram]

The truck is currently a vp truck and it dynoed at 600. I know it sounds crazy but we held our own with the vp setup.....and now i would like to compare the vp directly with the 14 mm ve. Both pumps are rpm limited so it should be a good comparison

[turboram]

Oh injectors are 6x18

[RCCUMMINS89]

Should be interesting.....

You'll have the fuel with those injectors and pump, properly tuned, to make 600-700hp.

VE's are even more fuel limited than VP's, and the 14mm heads are pretty sensitive. Must run at least 30psi at all times on a pulling truck, and try not to spin over 4K leaving the line. Try to keep the power in the 2600-3000rpm range in the middle of the track, run as much boost as you can without surging the turbo. With a hot 2.6 charger, you should be close to 600 with the VE! PM me for any more info. Not many 14mm guys around anymore. Also, I'd run close to 30 deg of timing if you can spool it.

the vp pump makes peak power at 2800 and dies after 3200.....i have spun the vp to 4800 with a computer i made only made a few more hp . I will be trying my different duel feed ,and my engineer friend is helping with injector sizing for rpm and desired fuel delivered

[cummins12club]

Keep us posted I'm very interested to see what kind of power this combo will make

IF only Austin Elsmore was on here....

[AHineman]

He'd add a 25% correction factor.

[RCCUMMINS89]

I like how only the people from the midwest have a problem with correction factors.

If they are correct, or not... go drive your truck in the hills at 5-6k feet and let me know how your boost gauge reads. It makes a difference.

Sorry, I'm not up with whether or not it is a needed correction.... but I do know my truck does not have the same power in higher elevation.

[RCCUMMINS89]

Sorry, I probably opened up a can of worms..... pretend the last post doesn't exist, LOL

I never noticed that, but it's true. I have to be near 350 WCHP (West Coast Horse Power)
