So what kind of numbers would this be on hanks dyno?

Looks like and makes sense that it would be on Marc's dyno at EFI Express which is known as "The Heartbreaker" so... My guess is even higher.

I think the dynapac reads higher then hanks dyno. At least ive always heard eddy current type read higher...

You're right so hank claims 4% lower than the local mustang which according to Google read 10-12% lower than dynapack so ~15%?

This is dumb I can't find his instagram. I'll wait for the whole story

Thanks for the link!

Holy balls!

lol. Whoa. So stock fuel lines are good for a lot with big pumps and pressure.

Congrats man! ... unreal numbers. Really goes to show the quality of the head work from Jeff.

I guess I'll be the first to say it, but that is laggy as fuck. Only 2k RPM of powerband if the rev limiter stays at 8k! Downshift to stay in the power and all that, yeah yeah we've heard it all, but no matter how you look at it, it's making real power for 2k RPM. I'm sure it's fun as shit though.

Something like an HTA 3586 could make 700ish whp, just as much if not more torque, and have a ~4.5k RPM ower band. Just something to think about.

You know all of this, and I'm sure the gears have already been spinning in your head...but just an observation Sorry I had to be THAT guy

Qsv time

...and rev it to 9K.

So awesome!

That last pull in that video...mother of god

You guys beat me to it, but these were my thoughts:

QSV would help...

I'm thinking this would be a damned good turbo for a 9000-9500 RPM engine though...


Can't wait to see some vids on the steet!

I'd be happy with my 2000 rpm's of 700wheel... allll day.

lol mage.

A qsv will give you 500+rpm and just way more meat down low.

We'll see how my brothers FP HTZ6466 works out. That's ultimately what I would have wanted but it didn't exist yet.

God damn that sounds good! Nice numbers!

Argh!

As a dyno owner/tuner, this kind of speculation drives me nuts. First off a Dynapack is not an eddy-current dyno. Second, the way the dyno operator performs the dyno pulls can have a huge impact on power numbers, regardless of what dyno is being used. Hank's dyno IS an eddy current dyno, and depending on how he sets up his pulls, he too can generate quite a range of outputs for a given car.

So, you've heard that eddy-current dynos read higher? Higher than what?

I've had a car (Honda S2000) read within 2 hp (1% difference) between my Dynapack and a Mustang dyno. But the runs were performed in a similar fashion dyno-to-dyno.

So, you think that an Audi 200 20V that reads around 665 at the wheels on Hank's dyno will keep up with Nick's 780'ish on a Dynapack? Don't think so!

Just for comparison, a similar weight B5 A4/S4 swap with 650 at the wheels onmy dyno did mid 10's and best trapped at 140mph.

Congrats Nick! That's a beautiful set of curves!!!

Those were quick pulls. It should spool faster in the real world.

They looked like 1 sec/1000RPM pulls, and, for reference, Matt's car, which he says spools faster on the street than on my dyno, was subjected to pulls of 2 seconds/1000rpm.

Just another variable to throw in the mix!

That is just plain bad ass. I'm sure you built the motor for high horsepower and that is exactly what you have. You are at the point that most people would love to be. That is one sweet street car and anyone cruising next you would never suspect nearly 800 horsepower to the ground. A quick spool valve would be nice to have if you can afford the extra 3/4'' of height. Awesome job. Glad to see that motor perform like that.

That turbo screams at 30+ psi.

Should be fine, dad had a qsv on the same manifold in a UrS. But maybe the hood is lower or there's less space in the 200, not sure.

Nah, he's got plenty of room to go up from the looks of it.

Hence the

Great job nick. Car sounds amazing. Looks like a proper built setup you have created. Very good ideas here..enjoy it, I'm sure it's down right nuts.

Brady, I understand what you are saying, and yeah, type of absorber should't matter at all.

That said, if you are using standard correction on a dynopac and letting the weather station do it's calculation with normal tire pressure and normal cool downs, etc, it should be the same across the board for dynopacs. Marc and my Land and Seas just read low. We don't fester with them or fudge anything at all to make them act like a mustang or a dynopac. We could, but horsepower isn't dependent on a dyno, but rather the magical formula of air plus fuel plus bang at the right time. Spool can be altered 100%. Like you said, if the dyno operator used more brake to slow the pulls down, the pulls should match the logs on the street, which is around 6200 rpm from what I have seen.

I bought my dyno used, and the previous owner added a standard correction to their plots to get them up to Mustang levels. They advised me to keep it set at zero, and just take flack. I have done that and feel good about it. Their chipsets, tunes and stock cars make around 7% less across the board, but in the end of the day, it is just about deltas and baselines.

Nick sent me his logs about a week ago from some 3rd gear pulls, I looked over the data, gave my suggestions for timing based off what I have seen on BT 20vts, and gave my speculation for horsepower. With Sean's 07k car at 645whp on my dyno it was consuming ~6500cc worth of fuel at 90%DC on 1390cc worth of injector ~.80 lambda. Looking at Nicks logs, he was running about 58% DC on 2200cc injectors for around the same amount of fuel at the same lambda, but not nearly enough timing from my experience. I guessed based off my dyno what he would make(roughly the same amount as the 07k car plus a little becasue of increased turbine flow), then gave him an estimate off what I have seen on dynopacs local to me at about 15-16%, and told him I thought he would make 720whp in his current tune on the dyno, and 780whp with more timing. I can load up the conversation if you want

So yes, I would bet a lot of money at 665whp 200 on my dyno would be even with a dynopack 780whp, especially if they are using the same amount of fuel.

So yes, I see it on a weekly basis. Guys come from dynopacks and dynojets, get on my dyno and freak out. I explain weekly to customers of tuners that rent my dyno that my dyno just reads low. Nothing wrong with that. I have a 2850lb e30 m3 trapping 152mph at 9.7 with 620whp on my dyno with GTX3582r on 1.06 hotside. That is a pretty bitching trap for 620whp.

Regardless, a ton of power. Congrats man. Wicked dedication and planning. Well done.

I did notice what you guys are mentioning. I'm just reviewing some of the logs now and am seeing that on the dyno it's spooling to full boost later than on the street for sure.
