Get yourself some sticky tires and run down the 1/4 you don't need a dyno for that, and it will give you real life results on the power your car is making. Dyno numbers are a joke. Track times are legit way to see what kind of power your making. At least from a whp perspective.

Dyno numbers are not a joke,in my opinion. Having a ball park of where you are at is a good "tool" to go by. But the most important is knowing where your power band is. I have dynoed cars that guys where shifting at 7,000+rpm and there peak power was all done at 5,500rpm on the dyno so pushing the engine that high did nothing for trap speeds and time and just beat on the engine more for no reason. Now.. going to the track making pass after pass will at some point tell you this but having some dyno information before you go I think would be a big help.
As a side note I had my own car that was used for a test bed for parts. "Dyno on Sunday ,print on Monday". Parts that company's would claim made a certain amount of horse power. Doing back to back tests would show many many times that there claims where not true. If you baseline your car at 440hp and a company claims a 75hp increase buy installing there parts and you gain 40hp...something just "aint right". Just my opinion.

With the remote tuning, do you have to reset your car back to stock mode to upload your new tuning, or you just upload the new tuning each time you add new mods?

99lightning

just reflash.

With the ec remote tuning sw, when you reflash with new tune it erases all old stuff and then puts new tune on ,all in one easy push of a button

c55asleep?

Ok. It won't be moving much for now. I'm getting the wheels redone. Once it gets going it clears up. But I'm sure it's running a bit lean..

miamiE55

Im planning on going to the dyno whenever c55asleep goes maybe Jerry can tune us both, I may need to go a little leaner up top.

Im also plannign on going to the track in the next couples weeks just for fun and get a ballpark idea where I am there , I been to the track once so I basically have no experience so well see how that goes

Sugar_Mouth

Ya it looks like after about 4800ish rpm you could use some leaning up. That will make a decent difference with just that one adjustment. You can see right where the AFR goes under 11 your HP also goes flat. You should gain some power between 4700-5700 rpm getting that AFR closer to 11.

Good time. 60 time needs to improve alittle. I would be happy with that after my Sc pulley and tune.

Mph seems alittle low.. There is more in the car. But good times for your second time

miamiE55

nitto 555s rear tires and it was 54 degrees , very little track experience

I ran a 13.1 at first with a 117mph then i did a little burnout and it hooked a little better but i hesitated slightly at the start so Im sure I can bring that down just a bit

Was this PBIR last night?

miamiE55

yea last night, it was cold so I figured i should give it a shot but everyone else was thinking the same thing...alot of cars I was the last to run of the night

kponti

OK so to all the "get to the track" guys, what do you have to say about his track times? Best et of ~12.3, best trap of ~117mph. Unless the track is notorious for giving slow times, the car is under performing for a dyno tuned E55 with all his mods. Yes I understand he is no pro at the track, but the E55 isn't exactly that hard to run down the quarter with tires like he had.

The AF map looks like a lot was left on the table, the dyno operators could be at fault with this. Communication is key and I feel there was a breakdown of communication in this guy's dyno session.

Hulk

Actually it is not that great a track, it's hit or miss on prep and especially since he was racing at the end of the night with street tires lol trust me he ran with practically no prep

c55asleep?

Good run brotha. Car is ready to roll.. Let's make some time to hit the dyno.

miamiE55

thanks guys, I was running really bad until I met a e55 owner out there (dave) and he gave me a few tips, he said with practice I could get it down a bit so I think its more driver error rather than the car at this point

Ls1toAMG

First off I agree to a point. Every car Dynos different anyway. If you want get technical. Their stock e55 on a unknown or not stated dyno with only a tune dynos higher than the tune and smaller clutched pulley on a dyno meter. That being said even on the same dyno cars will range 370-410.

That's whay it is of utmost importance that you search these boards for proven hands on gains. If you spend that time you would find a tune and a cluched sp pulley is worth 40-45 hp at the wheels. The tune is 20-25 the pulley 20+.

If you already have a good tune then the pulley is worth 20. It comes down to its equall to a 166 mm crank pulley.most claim the boost is the same as a 172 but the end hp does not equate. A car with a 172 will whip you.'its a safer cheap baby pulley where you won't F up your crank or have the stresses of a FSP pulley. This place has all the info you need. Also it's the only place you ever need to get the best price on parts. I got a sp pulley and green belt new for 275 shipped. Can't beat that

Not sure what the tone of your post is, and I have hardly any interest in dog piling the OP.

But you may have a point..

The highest trap doesn't seem to be congruent with his mods, nor does the 1/4. Bone stock I've hit almost identical numbers (trap and E/T during the same pass) at 1,300' with positive DA.

I mean no disrespect to the OP at all, but the numbers seem off somehow.

kponti

Not wanting to dog pile OP either. But I am saying his dyno numbers ARE indicative of what the car is running. And yes dyno numbers are usually very accurate for each situation.
Dynos are usually pretty close if they have been SAE normalized. Bad dyno numbers are simply a result of the operator fudging numbers. The main use of a dyno as I'm sure everyone knows is to compare before and after under similar conditions so as to see if mod does what its said it will do.

That's funny I got a text from a friend that said there was an E55 at PBIR.

I would have been there, but I ran into some problems with an axle. So I decided not to go. Plus I don't like rushing the job when it comes to my car. I'll be there next time.

You should dyno your car at Rage-Tek. It's a dyno jet and it's where Jerry come when he's here tuning. Let Jerry custom tune it and then head to PBIR with me and my car.

Hey guys! I use this topic, so there is no need to make a new.

Today I went to the dyno. 382.3 kw ~ 512hp and 838nm at the engine. IAT was abaut 45-50 degrees celcius.

84mm pulley and EC Jerry tune. Maybe the headers next.
