The "WildZL1" Build Journey

[Vicster]

For those of you who want to know, the last dyno pull was, drum roll....

765HP and 711TQ at the rear wheels at 6500rpm on a Dyno Dynamics dyno.

So 2 things that need improving.
1. A shorter belt as I had slippage lost almost 1.5psi, after the run the tensioner was maxxed out, belt stretch.
2. A larger fuel pump as my fuel pressure began to drop at 5500rpm.
UPDATE: CORRECTED THESE ISSUES!

Can I prove that I made over 800hp at the rear wheels on this dyno? Nope, but looking at the Dyno sheet you know it would have HP was still climbing even with my 2 issues.
The engine performed awesome, the tuner at Ross Performance is very knowledgeable and easy to talk to and work with. Big call out to Ken and Tom Thanks Guys!!!

So there it is, Dyno is finally done and I cannot stop smiling!!!

I'm not sure you were out of fuel. Your Inj. DC was 82% at 6066 RPM. I suppose at 6500 it couldve peaked but I cant see that. Did you buy the credit to flash the FPCM?

Yes I did, fuel pump voltage is maxed out, it just ran out of steam (I am running the Livernois Motorsports dual pump system). The injector DC would have been lower with constant 60psi fuel pressure. Here is the tune and log, and a pic of the end of the pull. Take a look and see what you think. He had to go rich at the end of the MAF to compensate as the fuel pressure started dropping after 5,500rpm. We still had another 1000rpm to go, the tuner did not even mess with the spark tables. I know that with the fuel and belt issue solved it is more than capable of 1000rwhp!

I am so proud of what I have accomplished, it is very satisfying that the engine had no hiccups or flaws!

Great numbers for only pump gas Vic. Sounds real nice.

Does the Dyno Dynamics dyno read low?
The Dyno Dynamics is known throughout the industry as being the "heartbreaker" dyno - because it breaks the heart of every man that thinks he has 500 hp when he really has 350. The Dyno Dynamics reads lower than the Mustang. It reads WAY lower than a Dynojet.

When Ken told me it reads lower I did not think it was that bad...

How do I compare my pulls to Mustang Dyno, or a Dynojet, or a Dynapack? Every dyno is different. If you want dynojet or mustang-ish #s you have to multiply by 1.18 or so, 1.25+ for DynaPack. But remember, this is just ballpark, as it is not linear.
(So to make it linear we divide by .82%)

So, Mustang dyno is 15% lower and the Dyno Dynamics is 18% lower than a a DynoJet dyno. So the math look something like this?
(So to make it linear we divide by .82%)

765/.82=933 (equals Dynojet dyno)
So if I was to run my car on a DynoJet dyno my HP at the wheels would be 933hp.

Then to get crank HP I need to multiply by 1.15% for drivetrain losses.
(So to make it linear we divide by .85%)
933/.85=1,098
So if I was to run my car on a DynoJet dyno my HP at the crank would be 1,098hp.

So even if the numbers are off, it is still Freakin AWESOME!!!!!

So the Winner of my poll is 1COR.1:18 at 1,100hp at the crank, send me a PM with your E-mail address and I will send you a $25.00 Amazon gift card! Thanks for Voting!

I am sure someone will have more to input on my numbers, please feel free, all I ask is that you include how or why you came to your conclusion.

My research on the web supports these numbers as being the most consistent.

From my calculations, you did well buddy!
Currently this is setup to mock the DynoJet. Mustang is available.

WoW, it really shows the belt slippage! I am glad you were able to run it for me! It comes really close to what I figured it would be. That makes me feel more confident about my numbers!

Thanks again for checking this for me!

Very impressive Vic. I'm just wondering what you would have made if not for the belt slippage. Seems like it had a little more left in it.

[FasNuf]

It should be fairly accurate as long as the car was in 4th gear, tire diameter is stock height and the rearend ratio is 3.73:1

Yes, all of that is correct!

Thank You!!!

Hey Vic, I love your optimism, but i think you're reaching here.

If you want to know what it would make on a dynojet, well then put it on a dynojet. I dyno'd HIGHER on both a mustang dyno and a Land and Sea Dyno-mite dyno. Search the internet and they will tell you both of those dynos read lower. Guess what, they were wrong. On that given day, using the correct weather station and correction factor, the dyno jet read LOWER. and even lower yet using SAE.

You have a beautiful build going (2 actually), and I'm sure your 427 with a 2650 will easily make 1000+whp, but not this one. I will have to respectfully disagree with the BMW M5 forum math. All I can share is my own personally real experience.

Curious though... even if you did make 933whp, why the thread title reads Exceeded 1000whp?

[FasNuf]

The best practice on any dyno is to get a baseline number before mods, then after the build, get the new HP on the same dyno The same atmospheric conditions as the baseline run would help consistency. The delta is what we're all really going for.

I was told by many people here that I would not even make 800hp at the crank, also if I wanted to make any serious power I needed to run E-85.

I put it in the title as a jab to those who said I could not do it. If I corrected the belt slippage and fuel issue so I could hit my targeted rpm of 7,800 instead of 6,500. I am pretty sure I would be past 1,000whp, as we did not add any spark to what I have been running. When I could not run over 6,500 rpm I called it quits and came home.

Doubters will doubt and haters will hate... I am happy that I did everything to this engine (except the block machine work and porting the heads ( I did open the exhaust ports more)) I designed the cam (Comp. Cams ground it to my specks) and picked all the parts and assembled it with my own hands! I am happy with the engine and it has blown away my expectations, it is only my 2nd engine build and it was done in my living room. I know a lot of shop built engines do not run this well!
So, I am proud of what I have accomplished and my Little Engine that could!
