Not sure why you are saying that. 800 on a mustang, through an auto, on 14 lbs of boost, I think would be awesome.

Arctic Vette

No bud i think ur misunderstanding. Im saying it be awesome too but i cant figure why it isnt doing the 800whp

realcanuk

I could be wrong... ( I was once I think LOL).... but I don't think its realistic to expect 800 at 14psi on a mustang, especially with an auto. On top of that there are so many other variables. Everyone is to hung up on dyno numbers I'm thinking.

Xtremespeed

I don't think I'd put much stock in those dyno numbers if he's running 8.59 in a 3200# car and only 570rwhp. Maybe I'm off but I don't see it happening. I would just let him tune it and then go to the track and get some trap speeds. Dynos are great tuning tools but the numbers vary so much, you really can't compare them.

Arctic Vette

I should have something for you on this today...

realcanuk

LOL.... talking about your car?

I don't know why you would compare. You have a fully built engine and am sure will be tuning much more aggressively, and I assume you aren't going to max at 14lbs. If your car doesn't make some big power, after all the money going into it................

Arctic Vette

Id compare because, besides the 3.33 and compression of being diff we have same exact build and A6...

realcanuk

Well you shouldn't compare... different animals. I don't know what pulley you plan to run, or compression you have, but I know what my car does, and I wouldn't expect the ops build to make the same power.

Back to the ops car.... buddy... don't worry about the number so much... let the tuning get done, and enjoy the ride.

Arctic Vette

Ok tks bud.


Anyways USMC will hit u up later..

Guys, Please-please-please Email us whenever possible. We literally cannot answer every phone call. It's physically impossible, we can't just hire more phone people because they have to be knowledgeable of the products we sell. We are far from a std auto parts store.

Your numbers do seem off, regardless of which dyno you are on, but there are way too many variables to properly help you over the phone or on line.

If we can help please EMAIL us and we will do the best we can to assist.

I can tell you I see a avg of 15% difference from a dynojet vs our mustang dyno . Hub dynos seem to read higher than that as well . a stock c6 on our mustang made 330hp to give you an idea . I wouldn't be totally depressed on the numbers ,unless you feel it being slower .The auto cars always show lower numbers but faster times ."what does your dyno sheet trap?"

usmcpony

He's was able to get a little bit more out of it. He said the tune wasnt far off.As for the huge difference in power. So far what I gathered is he tuned it on a Mustang dyno (usually 8-18% lower than dynapack), unlocked convertor (minus another 6-8% from what Matt at FSP told me), in 90 degree heat. Where ECS dynoed on a Dynapack (Dynos 8-18% higher than mustang dynos), locked converter and in March with the garage door open (shown in dyno video).

First off..

DynoPack dynos read high, especially the hub mount stuff.. It's not realistic... They are happier then DJ numbers. So don't put much stock in those numbers.

Next..
If your converter was unlocked on the dyno, and you have any type of stall speed in it at all, then throw your dyno numbers out the window. The numbers could be GROSSLY skewed due to how the converter works/couples up under load and wheel speed. It could be costing you 50hp, it could be costing you 150hp... Or more.

So either lock the converter on the dyno to get your numbers, or go to the track and see what it traps, that's the REAL deal...

I agree you should be making more then 630hp but, that could easily be close to 800 with the converter locked, depending on how in efficient the converter is.

I seriously doubt you are gonna make 800 rwhp, unlocked, with only 14 psi on a small cube motor...

FWIW, one of our local fast guys with a C6/A6 only dynoed 820 rwhp unlocked with a 427 LSX, YSI yet ran 8.70@156.

Get it to the track in some decent air and see what it does.

MARSC6

Didn't have a chance to compare with a mustang dyno yet but my dynojet numbers were within 20 of a dynopack.

realcanuk

This is what I have seen on my shops dynopak also.... fairly close in most cases.

DOUG @ ECS

All Dyno Pack dyno's are the hub type, and they are very realistic. Much better then a non load bearing DJ that's for damn sure. I have 1000's of hours on both.

I have had our dyno next to a Dyno Jet at Corvettes of Carlisle, we had two cars go from one dyno to the other and the numbers were 1HP away on a C6Z and 3 away on a C5. You could hold the graphs over each other in the sun and it looked liked you drew over one another.
Plus our last dyno was a DJ and the all the cars dyno'd very close to each other that went back on the new dyno.


14lbs of boost and 630 to the tires is IMHO a problem, period. The supercharger is doing it's part, something else is lacking and it's not an unlocked street converter.

realcanuk

For once..... LOL

630 definitely low. I was just saying I don't think it will show more hp with the 2200 at 14lbs.... then with the 1500 at the same 14lbs. I would expect more loss from turning the big blower. Should be in same ballpark though I would think.

DOUG @ ECS

You agreed when I sent you upgraded fuel lines for N/C, so that's twice.

Agreed though, the same boost on a 2200R up top will make less on the low end and there is bigger parts to spin causing drag. I would start with a pulley swap in this case, but I am only saying that because I do not know any of the other 100's of variables needed to make that decision properly.

realcanuk

Yes.... that was great service...
