During standard dyno testing, PVO engineers found that SRT-10 engines built between mid January and early March (about 250-275 delivered SRT’s) were assembled with intake valves that did not receive the specified intake valve machining, resulting in a potential loss of about 25 horsepower. :ugh:

Those Liberal bastages were screwing our bro's outa 25 hp, probably in the name of fuel economy...WAR TREE HUGGING M.E.'s!!!

I could post a link, but I think we all know where I got this info...it's in plain view for all to see...and about a three page thread now...should be a ten pager inside of a week!

Okay. Read the thread and now I'm up to date.
Interesting to see that the SRT is generally dynoing at numbers that are not considerably above the gen 2's. Certainly not representative of the 50 bhp increase that they advertise. Regardless of the spin (and the loaner, $300 and hand job by the local Dodge dealer's receptionist), not good news for SRT buyers.

Maybe if you spent more time reading and not pissing off devildog you would have known that. :lolcry:
I don't spend much time in the SRT section, cause I ain't got one....Devildog needs anger management classes, and a sedative!

Gerald I don't think devildog is going to let it die. This could get good, I am waithing to see what happens next. /images/graemlins/laughing.gif
I am not wasting quality smack on Devildog, that could be better utilized here on packetjunkie...So far, I only dropped a few choice insults taken from Craig's limited vocabulary...we'll leave it at that...but hide and watch, I'll post pics over there of every MOMO steering wheel we install up here!!! Two more coming up this week!!! /images/graemlins/laughing.gif

Damn....25Hp, that is terrible, I would be highly pissed if I had one of those vehicles with that valve problem. You don't pay $80,000+ for poor worksmanship such as this.....TERRIBLE :ugh:

I want to know what machining step was missed that caused a 25hp loss?

The problem is not with DC but with the valve supplier. But then again, the engine builders should have noticed something not right with the valves. It must be something that could have been spotted by eye to cause an average of 2.5 hp per cylinder loss.

I would guess a back cut angle on the valve wasn't performed and was shrouding the curtain area. I think I read that the cut nearest the perimeter of the valve affects low-lift flow, while the one nearest the stem affects high lift/high rpm flow.

I was thinking along the same lines but wanted to see what someone else thought. Would this not have been visible to the builder if they would have looked closely at them? You would think it would be.

Are the valves swirl polished at all? And I also wonder how many angles there are on them?

The valves must just have "missed" one step in the machining process. :bonk: I would sure like to know how that happened.
