Still not following.. The switch for full fuel pressure is flipped and the power went up...@ 65mph the power was leveling off because rail was dropping.. The first two runs show this very well... The third run never decayed but the power doesn't go as high either because of heat soak... It could be fogging the motor out as well since the run was pretty darn smokey. (run 3)

well josh i am probably one of the nicest people that anyone will ever meet. so my temper is fine. however when someone resorts to calling someone names when they dont know what is going on then i get pretty angry. i do apologize for the name calling. perhaps you could be man enough to do the same. and by the way my name is spelled beach not beech. maybe you could look into that. know back on topic
Hey....me tooo :D

Can't say the same for mr. beech, but that is okay doctor says to take 3 breaths then react. :hello:

My opinion on these turbo debates is I cannot justify spending the money on a product that dosen't have repeatable results and not dyno results as there are to many things that can change the outcome. Like I've said before for pulling your rules dictate how you chose which way to go so if it's stock appearing it's obvious and belive is why the cheetah became avaliable. For drag racing I look at what times are being turned with these products since I don't race dyno's and anyone can tune for maximum hp on a dyno to blow up the hp number but it dosen't mean it will work on the track. I guess we can all look at it this way. A stock apearing turbo ran 11.50's with other mods and has anyone else done it? Yeah guys have gone faster with same mods and a different turbo but it wasn't meant to be a cheetah 71.5mm performs better than the rest. I belive it was to show what it is capable of doing and how the stock bottom end can live under these conditions being an lbz. Pat is right if someone else runs the exact same setup the times should be simular and until then this subject will always be under the gun. I'm a drag racer at heart so what you run is what you run no matter how you did it. Guys claiming big numbers on a dyno and not backing it up at the strip look foolish in my opinion.

All three pulls are the same at 65mph regardless of switch position, then all three are the same at 80mph. Within normal dynojet pulls, everything is equal before 65mph (2750rpm)and after 80mph (3250), and the area inbetween has the same "area under the curve", two pulls both lose and gain in there, but average out. All three pulls are the same with an "event" in the middle. If you say it's a switch, then the switch has no effect on engine output. If those were my dynos I'd use pull three. There was no "fade", as the pulls are identical from 3250 up, high RPM is where fade hurts the most.

Well there's no way that you can keep rail pressure with 60% nozzles and 2600uS on a single pump so I'd say that our second pump made the spike as the log shows clearly. It also correlates to the dyno graph as well.. As well as the Ass-o-meter on the street.

I am sorry you took what I said to heart, perhaps you have a quilty consience(sp??)as if I was talking to you without really saying your name, because I did not call YOU or anyone else names, you did. Notice my post did not get editied as yours did?? Why is that? I mean, you are so calm and collected you wouldn't come out and insult someone who did nothing to you would you now??? Song and dance, song and dance.

I have nothing to appologize for, but I promise you when I do...I will.

but in the end each of the clowns talking the charger up ate crow soon after the LB7 Cheeter became a lame duck. quack quack

sorry brayden just proving a point. brayden have you come up with some kind of cotroller for you duel cp3 setup yet or will you continue to go mad max style. is there some way that something could be worked out to where the second cp3 only comes on when rail drops below a certain rpm ?. how are you going to maintain pressure with bigger injectors. thought i remember you saying that you are going bigger than 60 over after the motor is built

I can't find my HTT graph right now, but it had a bit more area under the curve than the PPE GT4088R, which I tested also.

I plotted from 2300 to 3400 rpm, the racing range. The red dots are from the Fleece graph. The flat line is the GT4088:

That's not comparing apples to apples or oranges or kiwi's.... the load programs are different, operator etc.. Comparing dyno sheets is a waste and you know that.

I didn't post to compare your built "race" engine to our "bolt on motor"

Like I said before, this was a tune to keep a stock motor alive.. You can't make big power on a stock motor with high CP down low... which is exactly what you're showing. Not saying it can't be done but 500hp is the standard by which people say you're playing with fire... I wanted to play with fire with this motor and show that it can be done safely if you have the proper gear on. They said you can't... we did... They didn't believe it, we backed it up @ the track with weight, logged data etc... Anybody got a polygraph?

this is crazy!

Why must everyone fight? This is getting worse than the DP! Unless i'm missing something there STILL is only a couple hand full's of mid 11 second trucks. Pat has agenda's or doesn't like when other people go fast maybe? I'm Not sure on that sometimes. Brayden Talks up his work (who doesn't even Pat). I spent about a year and a half fighting my truck not running like I thought it should. Some said Brayden's turbo, some said it was tuning, and some said it was just me. Could have been anything. I didn't put injectors in my new build because Pat kept saying you didn't need them! I went with what he said(he has been alot faster than me). Guess what? The injectors was my problem all along! This is not a slam on Pat. Pats has figured something out no buddy else has or a LLY is a LOT DIFFERENT than a LBZ. It is a unreal differance with injectors! I'm sure Brayden does stuff that others don't like. Thats why I think we all need to try and get along. We could learn so much more if "WE TRIED" to listen to each other. Everyone here has something to add that may know more than others in a given field. I think ego's are getting in the way from some good info. It's a shame. Jeff
