I bought tbals e55 about 2 months ago, car has been great to me so far with no outstanding issues.

As far as I can tell, and what Tony told me the car has the following performance mods:

Kleemann 168mm pulley
ASP pulley kit
E63 Mufflers with electric vavletronic cutouts. x pipe with no resonators.
kleemann mid length headers
Kleemann TCU tune
Eurocharged Dyno tune
Splitting cooling
bosch hd intercooler pump 4.4 liter heat exchanger
K&N freeflow filters

I dynoed the car the 2nd or 3rd day I had it and on the first 3 runs it put down about 460whp in dyno mode in 4th gear...after the 3rd run the car was only making about 430whp for 3 runs...so even with the upgraded cooling system I am assuming I still have heat soak issues...

What can I do to solve my cooling issues?

I also sold a few things and have an extra $4k to spend, I am thinking about going to a 180mm pulley and 82mm throttle body? What else can I do? with the pulley and throttle body would I need to upgrade the fuel injectors? anything I should worry about? What kind of power should I expect to make?

The local track opens next month and i got a long list of cars/people i want to embarrass so point me in the right direction guys!

If anyone has any links they could provide I would appreciate it.

thx for the help

 

EDIT** with the throttle body and pulley will I need a retune?? and how much should I expect for eurocharged to retune the car..?

 

Split your cooling system

 

The cooling is split, sorry.

 

You're halfway to a Weistec with that extra $4k.

 

4k is my max unfortunately, I would dip into the bank account for $1000 or so more but couldn't justify the more then 10k it will end up costing me installed...

 

How about a Shardul upper pulley and belt wrap kit. And yes, you will need to retune after a TB and pulley. I think Eurocharged's new policy on retunes is like $40 a pop or something.

 

Also, fuel rail and injectors should be added at this point. Will definitely require a retune.

 

could you point me in the direction for the shardul upper pulley and belt wrap kit? I quickly searched it, and it appears it deliveries more power threw the rpm...do you know a website?? and how exactly does the retunes with eurocharged work? Do I send the ECU and they tune it and send it back? how long roughly does it take? Also any sites for the fuel lines and injectors?? thanks for the quick replies!

 

Shardul is a member here. You can send him a PM. He's the bomb. He can get you everything you are looking for.

As for retunes, you can pick up a MyGenius from Eurocharged, they email you an updated tune, and you can flash it yourself. If not, you can do a remote tune with a laptop and a USB to OBDII cable. You will have to schedule a time to do it this way as they will have to upload it.

 

You don't have to have them upload them anymore. There new software lets you load the e-mailed tunes yourself without a MyGenius.

 

You may have a bad IC pump.

 

I copy what denroll is saying. No point in changing the CP just add the SC pulley and belt wrap kit. Add trunk tank or maybe meth to help with the cooling. But after a few dyno runs back to back and a especially a 4th gear pull you're going to have heat soak. After that you could look at the 82mm TB but for the price those really aren't the best bang for your buck. ~$1200 for ~25rwhp So it really depends on your goal. If you focus on cooling it will pay you back in repeatable HP and really there's nothing better than that.

 

I would add a meth kit and 90mm throttle bodys are floating around now. If you want 650rwtq+, take that weak sauce 168mm off there, and put on a 195mm crank pulley.

PM me if you need any help brotha, and I can suggest a small list that will wake your girl up big time.

 

Start with sneaky ecu reset

Then add some data logging equipment, smaller SC pulley, 82mm TB & meth/water injection. Then have EC dyno tune it.

That should humiliate all but the most hard core.

Good luck!

 

best way to get comparison when adding mods is 1/4 mile times. much more accurate than dyno numbers. You should run your car, see how it performs before adding extras.

 

I didn't see an LSD on the mod list, it should be considered?

 

I would typically agree with this, but having seen how incredibly different my car has ran when I had a 180 pulley I will have to disagree, I honestly don't know how to compare lol. These cars are ridiculous when it comes to consistency. Weather differences make them dramatically different.

I have trapped 120mph on a 60* night and then no better than 114 with multiple 112s when it was mid/upper 80s. And this has happened several times as well with different track visits. No changes in mods between all the visits.

If the OP saw a difference on the dyno that big with his 168, it will only be worse with more boost from adding larger crank pulley or a supercharger pulley on top of his current crank pulley.

If you don't have really good cooling (meth injection) or at least a big tank in your trunk or killer chiller having a big pulley for daily driving is kind of a waste unless you live in weather that is cool/cold year round or you just care about short blasts not exceeding 90-100mph. They are good for track visits where you let car sit and be cold for one pass with a tank full of ice feeding the intercooler but then performance drops shortly after if weather isn't cold.

I have hopped on a dyno with car warm and ran less power with a 180 than I have with just a supercharger pulley and on second run lost even more making difference worse. Only when car was cold did I make more power while with supercharger pulley I was running all runs less than 10hp from one another with back to back runs hot.

When it is cold out the big pullies or combos make the car an animal but once that cold weather is gone the performance drop is big with basic cooling upgrades (cm30 pump, 1.5 gallon separated tank, bigger heat exchanger) in place on my car.

That is my opinion on these big pulley high boost setups on daily drivers in warm climates.

 

Well said... basically hitting a dyno may give you a good number on the first pull or 2. Are you guys that spray meth getting tuned for it? and where do you tap into and what size nozzle? I may go that route only because I have an unlimited supply of it :-)

 

^ I couldn't agree more.

 

I would run more water than meth just using it for cooling and not adding boost/timing through tuning. With these cars having narrow band o2 sensors I think you need to keep nozzle size small though since the ecu won't compensate and the car will run to rich making you lose power.

 

How fast are your AIT's coming down after a good pull.

 

Exactly!
Most of our cars have a one gallon tank for the washer fluid. Just run a tap in the bottom of the tank, run one of the high meth washer fluids, add a boost activated switch, pump and plumbing and you set. You even have a low fluid level sensor built in from the factory.

No need to tune, just lower you iat's with the washer fluid and let your stock Ecu do the work.

 

i have a SC pulley for sale. Brand new, never been used. if you want it PM me.

 

WOW, Thanks for all the suggestions and responses guys..so from everything that Ive gathered my best bet is.

first and foremost, upgraded cooling? Meth injection kit-for more constant power and less heatsoak?-what kind of price am I looking at roughly.. including instal?

shardul belt wrap kit(which will be equivalent of 180mm pulley)-$550

82mm throttle body-$1k-3k? how hard are they to install?

fuel lines and fuel injectors-$500 bucks, can anyone give me a link to purchase some, or does anyone have some for sale?

can anyone that has put coilovers instead of airmatic chime in? I hate the "on air" feeling at high speeds, and the roads here suck..I am strongly considering coilovers, how hard would that be?

thansk for all the help
