First, for all those people who will never believe a damn thing:

1) It was the same dyno, but two different locations. Once was at Cecil, this one is at E-Town.
2) Tempurate at cecil was 80(84?), temp today was 74. Navigation unit gave same reading for altitude for both tracks, but its only accurate to within 50ft or so.
3) I did not set up a class 10 clean room, run purified air, strain my fuel, measure its particulates, manufacture same-to-spec actual brand new tires, move the planets in alignment, nor turn lead into gold in order to prepare for the dyno plot. I got to the track and said, wtf, while I'm here, why not.
4) Why did I put on JDM's pipes? Do I hate Sal? Do I think JLP is a commie? NO, I bought them because he had the shop time for me to get them installed. I'm a computer geek, not a car geek, my tool collection dosn't include an air compressor...I'm learning, but I'm no where near good enough to install my own exhaust yet. If Sal had a shop and time, I would have gotten his. How are the headers? Sal and JDM sell the same headers, I have NO idea about JLP's headers, go ask him. The headers are great, I love'm.

First time I dyno'd, I had a leaky intercooler with no fluid and a PSP intake.
This pull I had a JDM full-exhaust deal with twin single Mangaflows.

I didn't bother to run an A/F meter. I have no chips, I have no pullies, I even have the stock fan and water pump. :P I own a year 2000, birth date of Feb 2000. It had the intercooler recall inbetween pulls. I even get a Dyno discount now for being a "repeat customer". :P

First "stock" pulls best: 309rwhp/382.9rwtq
Best "long tube" pull: 337.8rwhp/412.8rwtq

 

Now it all makes sense to me, obviously the intercooler replacement is the REAL reason for the dyno improvements. In fact the new I/C is actually worth a full 30HP & 35 ft/lbs, so the truth is you lost power with the Long Tubes. Sorry I had to be the one to break it to you. Well, at least they sound really good. Thanks for your time. LOL

 

Good, strong numbers with lot's of horses and ft. lbs. under those two flat curves .

lol! If you're ever in Jersey, I'll buy you a beer, that was great.

LIGHTNINROD: thx. I was happy with them myself...

 

Those are plausable power numbers. I want a set of Kooks Long tubes so bad Saving my money so I can get um


I hope the price will go down some....soon!

You got the new bigger more HP intercooler to. My dealer told me i was the only one that got that mod. But all kidding aside nice dyno numbers good thing to hear that they headers give you and increase to. I was buying them just for the sound alone no matter what same like i did for my Bassani Cat back but nice to know i will pick up some hp/tq to.

 

SWEET, I gotta get up to a dyno soon.

 

Let me get this straight. You ran a dyno pull with no effective air charge cooling because your intercooler system was out of water? If this is true, I expect 90% of that 29rwhp increase can be attributed to a functioning intercooler.

 

To tell you the truth, I can't remember wether or not I filled it for the dyno run. My truck was eating 1/2gal every 300mi...after the trip down to Cecil, I decided to pull the fuse for the pump and run it dry until the recall....I can't say for certain wether I ran it "water-injected" on the dyno, or dry...was to long ago.

Judging from the dyno numbers, and what other claims to long tubes are, I probably ran it with water, but I don't really remember.

Holding to the hotly-debated "12% drivetrain loss" number, that would put my 310rwhp first pull at about 360hp, which would be about right for my truck...circumstance suggest I had water.

Not positive but I don't think the truck would be running that long to generate enough heat to loose that much power on a dyno run? Even still with stock 8lbs of boost? IMO I'd give it 10hp max from the properly working intcooler.

Anyone have any proof if my theory is right or wrong???

 

There are some peaple that reported on this very board that they thought there best 1/4 mile times came with a leaky intercooler.

Well.....they did!!!!

 

Wish I coulda gained that much!!!!!!

 

used the same dyno this weekend that i used in ga, temp was about the same

i picked up 4 hp and 7 ft/lbs with the lt's

 

hey beefcake, what dyno did you use here in georgia? i am needing to find one soon..............and nice piece on ESPN by the way, rusty is a buddy of mine, i sure woulda liked to been there to see ya'll race..........

 

Basic physics is all the proof you should need. When air is compressed, heat is generated. Period. Here is a chart from Eaton’s own website. It show the delta Temperature (outlet - inlet) from compressing the air versus supercharger RPM. Our supercharger runs about 2.1:1 crank RPM. So at 5400 engine RPM, or 11340 supercharger RPM, and 8psi of boost, the inlet temperature to the intercooler increases almost 160 degF.

A good graph posted in MMFF this last month showed that at 9spi of boost, the temperature coming out of the Eaton going into the intercooler was 207 degF. If you add ambient temp to the 160 I commented on above - there's your 207. Now MMFF also showed that our intercooler was capable of taking out over 200 degF. That doesn’t mean it will bring the charged air below ambient temperature, but it does say it’s capable of bringing it close to ambient regardless how much you throw at it. To some extent this is not a time dependent phenomenon. At some point the intercooler will become stable. But the point here is, until things stabilize, the intercooler is actually that much more efficient. In the many cases I’ve measured intercooler return water temperature as I’ve went down the track, our system is almost capable of maintaining ambient temperature over the entire 1320 feet.

And now beefcake shows his numbers. 4hp versus pawns 29hp. I stand corrected - 86% of pawns gain was from a now functioning intercooler.
