740rwhp 93 octane TRX write up

The hub dyno is most likely the factor for skewed numbers.

Yup, 3 for 3 on this forum with dumb hub dyno numbers. Most shops don’t know how to setup the correction factors properly.

Unfortunately threads like this just become misinformation for new folks on the forum.

You are not the worlds first idiot. Google hellcat FI interchiller dyno results so you can see reality.

Again, I’m not sure how to make it any more Mickey Mouse for you:

Show me a TRX with the same mods, dyno, and we can take it from there. Until then, it’s all white noise.

It’s not misinformation until you’ve proven it wrong. You can assume anything about any car, but it takes concrete evidence to substantiate a claim. I have presented my evidence, now I’m waiting for yours. Cheers,

Glad to see your truck running so good! Let's settle This. You got a Draggy? Or even better access to a strip? Let see some 0-60 or 1/4 mile times.

Easiest solution is for someone to verify my results independently.

No one needs to build another identical truck. You already have the unicorn. Just go get a time slip and prove it. We are excited that you are happy with your build but the numbers you are claiming simply do not mesh with reality. Please prove us wrong.

That’s more work. I’ve done my part, the burden of proof is on y’all. Let me know what the results are.

Let’s see some 1/4 mile mph to settle this. Dynos are very easy to manipulate but mph doesn’t lie.

Pretty sure this dude is trolling lol. There is absolutely no reasoning.

First of all... that is a good looking truck.

I'm afraid the gang is right, your dyno numbers definitely show close to 740 to the ground but in reality it isn't making that much. It is easy to manipulate those results and should be used for point of reference in my opinion. Case in point I made 758whp with a fully built, whipplecharged, cammed, heads, exhaust, ice boxed motor on 91. Do you really think you make a few less hp than me with a chiller and slip on pulley? With another 180 to ground you should be in the what high 10s low 11s? You didn't drop a full second in the quarter from some colder air and 1-1.5 more psi.

I wish the folks on here would a have a little more patience though and realize many on this forum haven't done this sort of stuff. I'm sure from his perspective he's thinking "what do you mean it didn't make that much it's right there on the sceen?!" Share your knowledge from a very layman's perspective otherwise the forums can be very off-putting for those trying to learn. Just my 2 pennies.

Hold on a minute, isnt 6th gear the true 1:1 on these rigs? A lower gear pull would skew #s quite a bit I would think.

 

[JKMTRX]

Great to see! The stock AIT sensor pulls so much timing a lot. Stock tune is more for emissions this increased heat soak. I live in south Florida and VERY humid. Starting with tune then will move from there.

I’ll add more info:

The shop I dynod at didn’t work on my truck, has 0 interest in numbers games. The build high horsepower gtr’s, race trucks, and civics, the shop name is JMS racing. I’m simply sharing my results, and am asking the community to either verify, or contradict them with a truck setup in the exact same way as mine. Unfortunately I have been unable to find a truck with the exact same mods as mine, so it’s hard to verify either way. I can appreciate and understand all of the wonderful sciences, but I also know our trucks run super hot. I was expecting 650-700 because my previous truck without a chiller and tune made 627 on a dynojet dyno at Lethal Performance.

I knew the conversation would get to this point, that’s why I posted it.

6th is 1 to 1 but is too fast for dyno is my understanding. 5th is what the tuner and shop recommended I run in.

You seem pretty certain. I recommend meeting up with AZDinopwr, lining them up and setting him straight.

Just show me a truck with the same mods dyno. That’s all it takes. It’s Mickey Mouse at this point.

love to see my fellow trexs showin their epenis on the interwebz, man I gotta love this forum!

I would be happy to detune my truck to 720 awhp, prove with a dyno sheet that that is where it is at, and then run them side to side with $10k on the line just to make it worth the time.

I get your point but patience is also reserved for those that deserve it. When the comments out the gate were condescending about “the op is clearly the only man on earth to think outside the box” to make this power level…. plus …. the inability to actually take the time to understand the math on why his dyno sheet is physically impossible from a conservation of energy standpoint then I’m not going to waste my breathe trying to be gentle and supportive. Others tried that route in this thread and his response was that they need to prove him wrong.

Combustion (stoichiometry) provides the absolute limits of hp per unit fuel and air. It’s not hard to calculate that his 180hp+ gain (890 chp +) is not feasible on 600cc injectors. Doesn’t matter how cold the air is… even if he was able to magically produce the CFM to make that HP, the fuel system could not keep up at the AFR that this motor commands. This is stuff that I know you understand and is as undeniable as gravity… yet the OP wants to say that dyno numbers somehow trump physics. We both know thats laughable given a dyno can be manipulated to read plus or minus 20% with just environmental variables. So how do you handle someone who is passionate about their opinion without actually understanding anything about the topic?

Not single person in this thread believes the OP and the requests to prove it with actual data that matters via a time slip or draggy are just going to be denied because of the threat of proving the OPs claim wrong. I’m sure if someone made the exact build and dyno'd less then he would claim the difference was in the tune. Some folks just lack common sense and aren’t worth the time. Others have done FI interchillers with an entire range of pulleys on this same motor and get 30-50whp out of the chiller. Plenty of dyno sheets out there to prove it. I’m sure the OP got that gain too. If he actually made 740whp then you really wasted a lot of money on a built motor and whipple
