my car is a strong running stock e55,I put down 471ftlbs stock and 406 whp

after 180pulley,tune and heatexchanger I put down 571ftlbs and 466whp

that was a eurocharged tune and the car actually ran like a beast at that point.I then went with a 82mmtb and it all went down hill from there

AWOL

dyno graph from the 466 pull?

I have a 175mm sitting in my closet and want LET to reflash me for it, but it seems like the top end really dies off on the first graph posted and Im just curious if most pulleys > 172mm cause this

skratch77

I think on the sheet I posted it was like 56xtq and 461whp I have to look for the 466whp one.I didnt have any problems with my car dying up top end with the 180 on the dyno.

the funny part is Im almost where I was with stock boost now as with the 180pulley on.

after I fix my oil sensor I will redyno with the headers on,I put down 430whp a few weeks ago and since then added headers and sometimes use my brothers renntech air box.

If I were to quess from my but dyno is that Im right around 450whp now and trapping almost 119

AWOL

Right, thats my point. I dont want to put on this 175 just to run the same times.

My times are on the stock pulley too

bahhhhh

skratch77

im running better times now than with the 180 lol

I am going to run a 168 or maybe a 172 pulley tops,I want to break 460whp on stock pulley first tho,Ill see where im at pretty soon.

the renntech box and kleemann headers with cat delete mad a big difference and Im dying to see what she will put down

The OP graph drop off was due to the tempurture, not pulley (directly). It was 100+ all day. This was the 6th pull of the day, around 4pm (hotest part of the day), and the best tune, however we were heat soaked. IATs were 105 at start up (due to abient)

The car would pull very hard, but by 5400, the timing retarded and fuel would dump due to the heat, that is what you are seeing. As I mentioned in one of the previous post, we compared this to 4 or 5 different E55's (Stage II) and not one of them dropped off, in fact, all were showing gains to 6500. So the pulley is solid to redline, you just need to make sure cooling is set, and don't try to tune/dyno when it is hot as f..

9/4 was the hottest day on record (Van Nuys CA)

From stock to where I am now feels like double the power. If I am at 60 on freeway and nail it, I get flashy traction light

Simply incredible power now. It really does scare me, however- Ill get used to it!

AWOL

hmmmm, decisions decisions.......

sorry I went off topic, I just fear changing an already simple, yet proven set up, and having it backfire. As long as the power keeps climbing, life is gravy - its just that the drop off really had me wondering.

God damn heat

Last thing I will say: If at all possible, get the tune done on a dyno. Jeremy loaded a "perfect" E55 tune from a car he had recently done with exact same modifications. It dyno'd 417. He got another 33 HP and almost 60 more torque after that. He said it was not uncommon, because what works on one AMG may not work on the next.. So if you want as much as you can get, it is essential to tune on the rack. I'll shut up now.

Meth and cooling adjustments will occur next with an 82mm tb. I should be back on the dyno within 3 weeks. This is my baseline with which to work from

Priceless, I love it.

Ali_E55

mine was clombing up to 6k rpm and then keeps @ the same till the redline, but no drops.

i think it is a tune thing, got to have a fine tuning to sqeeze every goat donkey camel horse out if it. lol also turtles if there are some.

Bramage

I agree Ali- I have considerable trust in Jeremy, and I know we did good given our conditions. I don't think any Camels were missed. Maybe hidden by heat- but there and availible.

I think if I got on the dyno today (64 F), the numbers would be higher, without doing anything at all. I do expect to re-tune with some additional mods.. Then we will see where are.

On another note- you guys all have had these mods for some time.

If I am driving along at 40-50 miles per hour and go wide open throttle, I seem to have a hard time keeping the car straight. This tells me that I am at the brink of power usability. 2000HP would be very difficult to actually drive. So my Torque (in high heat on the Dyno Dynamic) was 549. I have a hard time keeping the wheels on the road. I think that is good- but that is why it scares me.

James@ACG

Dane,
Sounds like you need a toe links and a quaife

skratch77

Take it to the 1/4 mile dyno

Bramage

Trust me- That is where I am going with this. Right now, Im afraid I will be bouncing off the walls.. I don't want to do that. I need to get out and tame this thing.

My slicks will help!

skratch77

What are you running for tires now?

Bramage

I know the track will be the true test, however I wanted to do some research. The Gintani Dyno has done a lot of cars, and many results are posted on thier site and youtube. Here are the results of the Dyno vs. Published Crank HP:

Platform...... Published......... Gintani Dyno
Corvette C6 430hp............... Dyno 323.4 hp +37%
2004 Gallardo 495 hp.......... Dyno 330.6 hp +47%
2007 Gallardo 523hp............Dyno 366.5 hp +44%
E63 AMG 507hp...................Dyno 339 hp +48%
Range Rover 510 hp.............Dyno 348.3 hp +46%


No wonder they call is a heart breaker!!!

BenzoBoi

I for one wouldn't mind low dyno numbers. I actually want the lowest numbers possible! In the end, that's all that it is... NUMBERS. Nothing more than that. Now take it to the track and see how it does, then you'll see how good the car is running and where you stand! Just my humble 2 cents.

skratch77

Its only a heart breaker if it was in shoot out mode.your car is dying up top from the heat of the 180 pulley

Don't get caught up in all the dyno numbers becasue they'll all be different. My car dynode at 447 rwhp on a mustang dyno but yet ran a 10.776 at the track.....

I will agreed that Gintani's dyno is definitely one of the lowest reading dyno's I've been on, besides when I dynode 447. Like Benzboi said, get the car to the track and see how she does. Comparing dyno numbers is just plain useless and a waste of time. There are cars here on this forum that claim mid to 500 rwhp with 600+ rwtq that can't even run in the mid 11's with DR's.....

Take your car to Famoso if you really want to see how your car compares to other strong E55's, there will be plenty of them there. This would give you a great opportunity to learn and ask a few questions.

BTW...don't let others tell you that your 180 pulley is the cause of your problems...bs. Look at cars that are running them and the ones that are not and judge for yourself. I'm currently running a 185 and more then likely I'll be going back to the 180.

Just my $.02.

skratch77

It was like 100 d on that day and he has no cooling mods that is why his top end suffered from the heat.All those guys running the big pullies have cooling mods with no cats and methanol.not to mention ice tanks in the trunk.my 460whp with 180 pulley was done in 50d ambient temp.

Also vinny hit the 10s with a 172 Not a 180 from what he told me.

Bramage

Im not worried about the pulley.. I seem to have heat soaked to the point of SC shut down easier before. I think the new HE helps a lot.. We only have an 1/8 mile in San Diego. Prior to 180 / Tune / HE I was running low 8's on 20" street tires. I will run there in 2 weeks with the DR's and all the new stuff. I expect (that if I can hook up and keep it straight), I should see low 7's.. maybe even in the 6's. I will do Fontana, once I have everything to my liking. Looking forward to meeting some more of you guys.



edit- I thought Famoso was up by SF.. I can do bakersfield. !!!!!

Meth.. That sounds funny

bassn_07

There are several people running the 180 pulley with HE only and no rear reservoir. Sure, the ones running near the 10's are doing everything possible to get there but they are on a whole different agenda than most. Your blanket statement about "All those guys running the big pullies have cooling mods with no cats and methanol.not to mention ice tanks in the trunk." is not true and only a very small percentage are running a rear tank and even fewer running meth. I myself had made passes in the 10's without ice, without meth, and with race cats.....

Vinny was running the 168 pulley before he switched to the 180. There's no way he would go from a 168 to a 172...no way. I'm not sure why he would tell you this but do a search and I think you'll find the thread where he states this.

Nice to see that you believe in the 180, and believe me it will make you more power with your cooling mods over the 172. It has already been track proven and I don't see how anyone could deny this. Maybe a 172 will allow you to be more consistent but IMO it will not run faster than the 180....no way.

Running low 7's or high 6's with your mod will be very hard to achieve. The quickest cars in the country run anywhere from 6.7 to 6.9's. Just recently I made a pass in some warm weather and I cut a 7.1 1/8 mile time with a 11.022 ET. I would expect 7.4 - 7.6 with DR's and a good launch. This would put you right around the 11.5-11.6 where healthy stage 2's should run. Once again this is just my opinion and what I've seen.

Attend Famoso and I'm sure you'll have a great time.

Worth the wait

I would add the Quaife to the list of upcoming mods. A car with your power, it will be night and day.
Good luck, your in good hands out there.

E55Bullet

Bassn, These cars are just too weird and run completely different from one another. I have a 172 with cooling running 11.7s I am going to switch to a 180 with headers and cat delete to see what more I can do..but who knows, lets just hope it dose not get slower! Good job 0p with the numbers!

Bramage

I'm signed up for Famoso, and will pay this weekend, which guarantees my being there.

We have an 1/8 mile here in SD so I can practice launching and 60'... I've been three times so far, and can get a couple more in before the trip north.

My best 60' on 20" street tires was 1.81 (norm around 2.0) .. Best 1/8th was 8.30 sec- (That was all stock)


Ill get some practice in with the DR's and the new mods. I know I will not be close to the top of the pack at Famoso, however I know I'll have fun, and I'm looking forward to meeting everyone.. Even Sean Thanks everyone!!
