I just wanted to post my dyno numbers from my engine work and tune.

1050x injectors, Metco Pulley 10% OD, 180 T-stat. I returned the spark plugs because they told me its a waste for what I did and would have no consequences to adding any power or performance from using them.

Wound up at 664whp and 626 torque. went up 3psi in boost.

Feels much stronger from 40-100 mph.

All in all this was very worth it. I will run my 0-60 times this weekend.

That seems kind of low. Mine, bone stock besides a JLT CAI is around 640 whp.

I dont know what it should be or shouldn't, Im just reporting back with my results. Certainly feels a lot quicker and pulls significantly better.

 

[scottiekay1973]

the big issue was the heat of the engine and getting it to cool down between pulls to get more out of it. the garage was like 95 degrees with next to no air flow other then the fans running at the mouth of my car.

I believe bone stock at 707 HP yields a 15% decline at the wheels giving us roughly 600 HP at the wheels so he had a pretty good increase according to my numbers.

Yeah, I bet that is what was killing the numbers. I bet on the street with the in car dyno, it is much higher numbers getting much better air. You know what your 0-60 or 1/8th mile and mph was before the upgrades and where it is now? That'll really show what kind of gains you made.

If he added an upper pulley, those numbers would get much better.

 

[scottiekay1973]

My best stock 0-60 was 3.5. I will measure the new time this weekend. My 1/4 mile no clue. Ill hit the track soon. I asked about the upper pulley and they suggested against it ( I cant recall why exactly ). They were pointing me to meth injection as next step. I was told to not bother with headers because for the $$ it was a small gain for a big cost.

I just want to question this... how is it a intake alone produced as much HP as what I just did? I thought our trucks put out like 565 to the wheel stock. I should have saved my $ and just went with that.

All engines run a bit different on power, ranges I've heard bone stock are 550whp to 620whp. I guess mine is one of the raped apes. LOL Bone stock before the CAI, it was at around 610 and with the CAI, around 640.

Dang! I got a dog then.

I’m just curious why your tuner is taking such a different path from what’s been proven to work, especially since the results do not seem to support their approach.

 

[scottiekay1973]

No clue they have done 3 of these trucks and all gains have been around the same give or take 30hp. They suggested against the upper wheel due to over boosting and creating too much heat. I think that was the reason. At the end of the day im happy with what I got for the short money i paid. I can always add more later.

 

[Lil Hemi]

There are various diameter upper pulley applications, seems odd that they are anti any upper. At the end of the day, if you’re happy then that’s all that matters. I’m sure you’ve already gone to Livernois website and compared your build against a similar package to see if your numbers are in the ballpark. If not, that’s what I’d do, just to see how ur doing $ vs HP.

Forget dyno numbers. There’s no questions how much power you are putting down when you get a track slip.

Dyno in a different gear and you’ll see a 30whp difference. Waaay to many variables to compare dyno numbers.

Nah, I wouldn't say that. LOL Remember as you stated, it was really hot in the dyno room and no real air movement. See what the in car dyno says on the street. I bet it'll show closer to 680whp or so.

 

[dragpac]

640 stock what kind of dyno were you on?Livernois said 580s is a good stock one.

That's with the CAI and it was a dynojet, but the in car dyno is very similar also.

Exactly this.... Different temps/ humidity/ how many pulls you have done.. Different dynos....

Mustang vs Dyno jet.... List can go on and on and on. People need to let the horsepower numbers go and go off of real world results. IMO Dyno numbers are good for your tuner to compare calibrations with each other but other that that... Please take my truck out on the road and tune it lol.

Good numbers! I think a lot of people don't realize you didn't throw on an upper pulley. The lower generally affects torque more than HP. 3 PSI is ~60 RWHP in boosted setups, so I think 660 RWHP is dead on. Like others have mentioned, I would have definitely thrown an upper on if I were going to void the warranty E85 and an upper will net you another almost 200 RWHP!
