Cylinder Head Shootout

Gentelmen, I do not is any way what to highjack this thread, but the base B&G stage II tune has a max of about 26.5-29 peak WOT timing based on the vehicle modifications when we build the calibration, we have never commanded 30+ degrees on any basic Stage II package. Certain vendors in the past have requested 30+ degree WOT timing packages but again that is not normal but requested, and we have always stated for the past 5 years that the Hemi's do not like alot of timing,but they can make real good power in the upper to high 20's at WOT.. We have done hundreds of calibrations and alot sold through outside vendors that were built on there request and I will say again there are many differnet variations of the base stage II calibration. Again we build the tune based on engine mods and or customer request so not every tune is the same. Hope this helps

 

Amen Dave!

 

Yeah I got something to add, This isnt about Horsepower. This isnt about peak numbers. This is a comparison of 4 vendors heads. We could say type A heads looked beautiful, Type B heads looked like this or that, Type C heads had such and such retainers, Type D have such n such valve job. This is a comparison of the different choices the mass public LX community has been purchasing. No one set of heads is gonna just blow all others away. A/f's on the test so far are so so close there is no need to add/pull fuel.

 

Hey PPP-Tech, I did a dyno comparison of my PMT CMR tune and the email B&G tune. You want to get your email tune in the mix? Had some pretty cool results.

Read post #136. lease:



I don't drop names, I reference them when called upon. It's a simple fact that Diablo based their canned tunes off Dave's B&G PCM reflash, accept it and move on. I wonder why they didn't call you instead? As an [email protected] with 22-24 degres WOT timing on 104 race gas from a built 392 is one hell of a way to show that you know how to tune...:bye:

 

You missed this part:

My Jeep made even more power with 30+ degrees (per my request) than it did with the intial 28-29.

 

We are not doing email tunes anymore. In order to do the right, it takes too much time for the cost. In order for the email tune to be any good, it would take at least 5 emails back and forth. If it is a PPP product, I will do it as I know what they like, but for the competition, I would be starting from scratch and it would take some time. Take Trojan for example, he has 100 dynos on his car to tune it properly, imagine trying to get the same results through 1-3 emails. I can send you a very generic tune, but I dont expect it to be any kind of a record breaker or industry leader.

 

You make me laugh. You've been clowned here and you still want more. If I search your name all I come up with is you arguing amongst the mass. I looked in your vendor section I saw a bunch of topics by you with no replies. Your showing my a lot. As for the 11.9 run, you have no idea what shape the car was in during that run, hell we just found out ourselves something was a miss. The car most likely had a mid to low 11 in it. So do us all a favor here sport and move along.

 

No doubt it's a great idea in theory, but it appears the execution could be handled a bit better. Regardless, it's not my test. On with the results!

 

LOL, you've done nothing but backpedal and make excuses. Woulda coulda shoulda, what was your VTEC broken? :supergay:

Let me know when you buy a clue or stop purchasing your builds from Kmart/Indy (evidently it's the only way you'll obtain any credible knowledge) until then I'll be anxiously awaiting the results of your oh so non scientific test. :rofl2:
My website hasn't even launched (just started selling products in the past 3 mos after over a decade working in the automotive aftermarket) but I'll gladly bet you dollars to donuts my 6.1 H/C package waxes your 392 build all day long.

ps--If I ever end up agreeing with the masses, you have my permission to shoot me. Sometimes things get a bit heated when someone speaks the truth with the knowledge to back it.

[email protected] w/ 22-24 degrees on 104 oct. FTL! LMAO. Cya.

 

I totally respect that and leave it as is.

 

OK guys. This has been an on going good discussion. I see we are starting to head south again. Keep it civil, stay on topic. This is not a maximum effort peak HP, king of the hill shootout. It's buying a set of bolt-on heads, and seeing what you expect to get in our world, not a max effort tweak it till we can't tweak it no more. I respect the efforts and look forward to to results. I still have PPP/INDY MAXX heads on my car. Never had an issue, no broken or cracked valve springs, which seems to be prevalent now. Dave told me way back when I got my Stage II that the 6.1 stock saw only 19 deqrees of advance at WOT

 

Hal,
Understood. However I've logged multiple SRT8s that have shown 24 degrees at WOT stock. Hell, you can even see 6-7 degrees of STKR stock.

 

Only asked a question which still hasn't been answered.

 

I feel the love! :king:

 

Never really saw it, really didn't pay attention back then. The Stage II on my car was pulling up to 24.8 and the Stage III up to 28.9. Only doing 19 now for my mild N2O tune. Dave told me no one had issues with the Stage II tune with N2O.

 

It's OK Erik. Those in the know, know who that was directed at. Even the one's thinking about it.

The beast has been awakened. Giving Ron a break. LOL

 

This is completely FALSE!

Octane rating has no direct impact on burn speed. The octane rating of a spark ignition engine fuel is the knock resistance. So to make the statement that you will loose power by increasing "Octane rating" is just plain nonsense!

I have to agree with Dave, HoP, and PPP. These engines don't like a lot of timing. These are not old school chevy 350's where you just put in 36 total and call it a day.

Just to be clear… we are a MOPAR CMR dealer. It maybe time for some people to step up and purchase the CMR software.

Just my .02.

HoP… Sorry if I hijacked your thread.

 

I am fairly new to this site and I have to admit these new gen Hemis are making some power, I was also at the rumble there were some very fast cars there unfortunately my day was cut short by a smoked piston #3 of course.

The guys that are tuning these Fuel injected computer controlled vehicles are truly talented and have a lot invested as far as time and money, me being a truck guy I have learned to tune my own stuff and I made one mistake just one 10.5.1 compression 28 degrees of timing and only 100 oct at 12.4 afr two steps colder plugs indexed I might ad. Engine temp 180 no KR what so ever and boom some of you may have seen it or heard the knocking after my burn out.

So the only two variables were compression and timing I have 47,000 miles on that engine and just increased compression and have been tuning it for two weeks and everything was perfect as far as the safe parameters except timing.

All of the LS/ GM fuel injected computer controlled engines don't like timing either they make more power at 20 to 24 degrees of timing at wot, Direct port fuel injection seems to be part of the reason. Anyways I hope I didn't over step my being new to this site I just thought I would ad my two cents coming from experience. Lonnie

 

Stopwhile you still can, The more you talk the dumber you get.
Bring your ass to the track we'll see who wax's who. :bye:
