. Anybody got any advice or experience on combo

Hi

I currently have a smaller clutched upper pulley. I would guess that having this pulley and a 180mm crank pulley is going to cause some issues for you.

I would seriously consider a 168mm or 172mm crank pulley and see how you go with that for now.

I'm running a 180 with the clutched upper. I saw about 14.3-14.5psi and a consistent 16psi after the belt wrap kit. I strongly suggest running a BWK if you plan on boosting that high... you're leaving power on the table (for those also reading this thread, I know the OP already has a BWK).

At 16psi, you are still within the range of the MAP, although even if you were hitting 18psi you could use a map clamp and relieve any issues.

I'm on E85 and water injection. The temps will jump about 10° and then level out when the water hits. No harsh engagement, other than the neck snapping torque.

+1 on the neck snapping TQ

You've piqued my interest.

Rockmullet are you using. A map clamp???? Or you're just mentioning if Someone hits 18 psi They can use it? Also I really want to hear people's experiences, I'll post up this other link but I didn't want this thread to turn out like the other one. dead in the water, so let's hear some results guys! If you read the other link you can see a couple other members that have a combo set up.... Now where's all this precious info that We need???

The stock MAP's limit is around 17psi, anything further and you need a MAP with a larger range or lower resolution.

My experience has been good... not sure what more I can say, lol. The combo works well.

What's a BWK?

Belt wrap kit. Eliminates supercharger belt slip. I hear even on stock boost it will provide more consistent boost numbers and a slight increase in psi... for me it was 1.5psi

That's awesome that the combo works great, are you using a clamp? Do you ever hit the max PSI without a clamp? If you do, do you just throw a code? and if you do, under what circumstances does that happen? wide-open throttle for an extended period of time.....

Never hit 17, I am not using a clamp, you'd probably throw a code. You wouldn't see boost creep in the upper rpms as you would on a turbo car, you'd see it peak on throttle tip in and then stabilize, but I've never seen that high of a peak in this car

That is awesome ....officially ....thanks for the clarification. I think I was just overthinking it. I have some free-flowing exhaust and headers on the car anyway, that should help keep the boost a Pu$$yhair lower than a car with stock exhaust Thankful for the input, anybody out there that had to run with a map clamp? Anybody out there who has some negative input or experiences with the combo I'm talking about? Any information that would deter someone from putting this combo on their car?

Sounds like you have a lot of supporting mods (cooling and exhaust) to handle more boost and neck snaps.

I run a 168 and smaller upper.. No problems at all.. See mods below, Go for it.. Just have adequate cooling and your fine...

Running a 195 so your planned setup should put you in that range. On the torque app I have hit 16.5 psi and have no issues with my car. Your cooling will be just fine with meth, KC, and trunk tank. That's what I have and again no issues.

Nice pictures on the install on the other forum H

I thought I recently read a thread that mentioned something about the heads lifting from too much boost...that they need new head bolts, if I recall maybe it happened on sneakyneons car? https://mbworld.org/forums/w211-amg/...neons-e55.html

Rockthemullet did you have this issue? I quote you ....

Interested in doing this as well been hunting for a 168 lower

Most people bypass/remove the heat exchanger with Killer Chiller. I did. I was told it drops the water temps a good 10 degrees. The HE will be working to warm the water up. on e a 100 degree day my water is 40 degrees. Running through the HE would be exposing that cold water to much warmer temps. If you have meth you have a pretty good fail safe. Also you have a clutched pulley so SC will disengage if your temps get too high. What sized upper do you have anyway ? Someone had a list posted with the amount of boost different combos made. I was tempted too but I dont think I will until I at least get a bigger tank or meth.

I have 168 and 84 with extra H E and trunk tank no problems 03sl55

I did have my heads lift going about 160 on 14.5psi and before water injection. I had some coolant consumption from the moment I bought the car so it may have been hurt before I started squeezing it. I can't say you'll have the same issue but it is something to consider
