E55 Stage 2+ problem with Power
Hello. I have e55 from 2005 with currently in the car I have
1. bosch injections 550
2. water pump 010
3. heat exchanger from eurocharged
4. pulley 84mm
5. pulley down 180mm
6. loop-through exhaust system without catalysts
7. UPD converter.
I bought exhaust manifolds from , and an XL heat exchanger from Moscow Supercharger. But I have not mounted it yet. I have so far had problems with the temperature of the coolant. (94-101 *) car with such modifications on the dynamometer obtained 520 horses. RaceIQ did the program. Anthony wrote that it was the temperature's fault. so I have exchanged all the coolers and the temperature is in the 85 degree Celsius.
I was not measuring the car. tell me where the problem may be? maybe lack of rail fuel problems these problems?
when I bought injections, they did not offer me to buy a fuel rail. can it be the reason for such low power?
thanks for answers

Our ECU pulls timing in 3 tiers:
95F is 3.5 degrees
113F is 6.3 degrees
149F is 9.5 degrees
You don't have enough cooling/ supporting mods for a 84/180 pulley stack. You need at the bare minimum real long tube headers with a full 3 inch exhaust to the muffler for that amount of boost.
This will get the motor to breath and maximize flow.
Next you need more cooling. Adding a second heat exchanger will speed up your recovery along with a trunk tank to give you more fluid volume.
You'll need another pump in the back to push the water/coolant from the trunk to the blower and so forth.
This will give you lower starting temps. To combat the intake air temps from rising too high during the pull you'll need to add a water/meth injection kit to slow the temp rise down during WOT(wide open throttle).
For now put the stock supercharger pulley back on. Once you have the supporting mods then slap back on the 84mm pulley.

Your issue is high intake air temps not engine coolant temps. You need to monitor what your intake air temps are during the pull.

Hi,
maybe 3" is even too small for a healthy boosted 5.5L V8 sc engine, 3.5" would be better. Keep in mind the supercharger is consuming up to 100 crank horsepower itself. You need to look for a dia that suits the total hp level.

At least you need to log boost, AFR, timing and IAT on the dyno to see whats going on. The good think about box tunes is that they work for a certain combination (pulley/headers/tune). Once it gets more special like stacked pulleys, injectors, intake etc. you need a dyno tune.

I don’t see power being down at all. But cooling would help. Trunk tank is easy. Then add meth injection if you want more. I gained a lot of power when i added that. And always could add a Killer Chiller.
My power setup was
195 crank
injectors
looped rail
82TB
renntech airbox
MBH headers
killer chiller
trunk tbak
meth injection
all tuned by Tony and I made 521hp/668tq on a Dyno Dynamics dyno.

Thank you for your answer!
I switched stage 2+ to stage 3+
+ Meth injection AEM
+ cold intake
+ 82 Throtlle body
+ EGR Off
+ separate compressor cooling system
+ Ecu program MSC supercgarge
+ fuel rail
. I installed methanol, but I don't know at which PSI turn on start and at which max psi set the end. maybe you can tell me I bought the program from MSC supercharge. I'm happy, but AFR increases to 13.5. I don't know if it's the fuel pump's fault.
On 1, 2,3 gear tge car drive very fast but in 4,5 afr and EGT its big 13.5 and 1600 F ( with meth 1700)
I dont know why tgis car dont have 600HP...
Maybe you have whatsapp?
