It was HPS, but more of the Gen II's that tried to copy Kleemann than the Gen I's.

deyainrdy4ds

are those 466hp claims real? thats almost 200 horses over stock


anyone know how much labor would run?

deyainrdy4ds

just got off the phone with the seller....time for some heavy research...any input on it would definitely be appreciatedd pleaseee

Hersh-

YOu can't just install the S/C. The ECU has to be reprogrammed as well.....so you gotta figure out who is going to do that.....

Best bet is to search posts by NitrogenBalance and Silence in the C43 section. HPS Gen1 does not require ECU tuning but I'm sure it would be better with an ECU tune. 466 is too high. I think nitro picked up right around 110 at the wheels for a total of around 340WHP.

There are a lot of negative posts about HPS. I think the majority of that stems from their Gen2 system that had a lot of problems out of the box (requiring a lot of modification to work well) and also from Gen1 owners installing it on a 5.5 where the SC seems to be undersized and works better on the 4.3

You should probably take some time to read all the negative threads in addition to Nitro and Silences just to make sure you know what you may be getting into

deyainrdy4ds

ya he said gen1 doesnt NEED the ecu retune but im sure i could find a place....gen2 needs it.....i just read some quick threads and wasnt too happy with what i see....something about only 40hp gains ??

and ya that 466 number is on a 55....380 was the number on 430s (to the crank) .....so that nitro guy did pick up 110 to the wheels at the dyno? did he have a gen 1?

ZEEK

wow hersh, your goin all out man. Good luck, hope it works out for you.

I was one of the first to get the GenII and have many posts of my experience on this forum. In conclusion, the housing is poorly designed and air flow is very restricted. The MP112 is the same blower as the new Kleemann blower but the HPS kit needs some mods such as a bigger inlet and a intercooler replacement that does not block the air flow inside the plenum. It should cost you another $500 and you should have a good performing unit. Mine gained 90rwhp over stock but I sold my unit before I did any of the mods described above although Techtune did 12.1 1/4on his SL500.

I think those low 40-60 HP #'s were primarily on the 5.5 engines. The Eaton MP90 SC just seems too small to work well on that engine. It appears to work better on the 4.3. Heres a link to one of Nitros threads right after his install. HP #'s are on post 8

I too spoke with the seller. The owner has a E55, Jim from mech-tech told me that Gen 1 kit is for the 55 motors. If you have a 430 than it may cost more $$$ to convert (Pulley)

BalboaIslanddud

AMGSC. Is right there were problems at the beginning. But Jim from Mech-Tech told me those problems have been fixed some 2 years ago. I think u took the blower off 2 years ago. So really what you have to say is based on that. Which does not provide any fact as of today. Jim told me hps or him has a new software tuning guy and fixed the housing and cooling system. I should find the e-mail and post it.

Second, how is your car doing at Vadim's? I know its been there over 4 months now? Any updates

BalboaIslanddud

I did talk to Wali, he is going to change his post. Then kit is for 55 motors only. Kind of miss leading to 430 owners.

AMGSC

If that were the case, then why is this brand new kit selling for such a low price?

I have another thread on my build that you can follow. Almost done but it does take some time to completely build a custom engine that will yield 700hp and set the new Mercedes drag time record if all goes well.

BalboaIslanddud

AMGSC - I don't know why the kit is 6k now. Jim told me someone bought HPS but dont hold me to it. Maybe they are clearing off the goods off the shelf. Makes sense if you are selling it. Who knows, but 6k is a good price. I'm trying to get Jim to install the kit for 1k but he wants 2k

Nice to hear about your project. Can you attach the thread for us to read.

deyainrdy4ds

FML ....so its definitely only for 55 motors?

suicidal4life

From looking thru the HPS directions there is very little difference between the gen1 55 and 430 kits. Basically pulley size and a spacer plate. Both of these items can be easily made by a machinist.

55 ON IT

It's not just for the 55. Like suicidal said though, the gen1 is ideal for the 430 motor.

deyainrdy4ds

ok so im confused...what about what post #15 said???

suicidal4life

Externally the 430 and 55 engines are almost identical so it will bolt up to either. The difference in the HPS gen1 kits are the 55 comes with a smaller pulley to spin the SC quicker in an effort to increase the boost to make up for the larger displacement of the 55 engine. As I mentioned earlier the Eaton MP90 SC is too small to efficiently supply the 55 engine. The HPS kits were originally produced with the 430 in mind. The other part that is different is a flat metal spacer between the mounting plate and the SC that is about 3/8" thick I think this has to do with the smaller pulley having a slightly different offset. The rest of the kit is the same for either engine. There may however be some differences in the piping to the air cleaner between the different models (CLK, E, C43, etc) These could probably be overcome with aftermarket tubing.

Ghostrider

So if a person were to install a 55 kit on a 430 would they need a new pulley and ditch the plate or would it be okay with the smaller pulley installed?

What is the word on the porting of your supercharger? Are you really doing SLR cams???

Ghost....are you about to GO BIG??

I'm just trying to keep my options open... Doing a little homework. I'm thinking I need a little more power:

I was driving home to Houston , I mean Mexico, this past Christmas, coming down I-45 right outside the Woodlands. It was me, this new Challanger and a few other hanger-ons and we all had been changing postions on the two lane highway for about 20 or 30 miles. Traveling in packs always makes a drive a little easier for me. Then we got to the four lane, and that's when the fun really started... Me and the Challanger were side-by-side doing about 75, and then we're off!!! Leaving the other behind and a clear stretch in front, we just open them up! He gets the drop on me cause that 6.1L is no joke, but at about 130 I catch up to him, and at 140 I'm nose past him, he lets off and then, so do I.

*Kill Confirmed*

Fast forward to this past weekend, I'm leaving class and there a C5 Vette with copper paint, matching 20" rims and a loud exhaust. We are on the streets, waiting at a light, he punches, I punch and jump ahead of him a good half a car length but he catches and passes me. Damned camshafts!!

*Kill Confirmed*

So I figure I need a little help on the low end, it'll either be a supercharger or nitrous. We'll see what the future holds...
