Need Advice on Adding More Power to HPS SC
if you really want the headers. RENNtech did not agree to remove mine
It also adds around 20 hp.

The more boost you run the more the reliablilty factor deteriorates.
Vadim, no way i am question your knowledges but is it every cars and set-up are difference? Have you ever seen this happen on an HPS set-up? I'm sure you based this on Kleemann kit, right? The reason i ask because i going with the same route as AMGSC. He will be running at 7-7.5 psi.
The more boost you run the more the reliablilty factor deteriorates.It would be smart if based on facts and not opinions. Have you or know anyone done any testing on with this set-up? I'm trying to find the facts here so i can make that smart decision. Btw, regarding to your "The more boost you run the more the reliablilty factor deteriorates". Absolutely true if not tuned right. Same go with putting a SC on any engine but we did it anyway !!

This goes for the CL65 and SL65 as well.Low compression slugs in the V12 for turbocharging reliably..This is also for the sake of the motor not grenading like yours will if you are not careful.I'm for you and not against you my friend.
Man I hope they sort the foolishness out.I figured they have got something very good at a very afffordable price.
We're all gunning for you though man!

I'm getting the smaller pulley, and ECU if they can do it when I'm there maybe even get the bigger injecters as well if the price isn't to high.
I'll also be getting a DYNO, and posting it as soon as I get home, I don't think the Dynos are fraudulent, When I had my HPS II installed the before dyno 220 rwhp & after install was 310 rwhp 320 rwto the power after install was a night and day difference..(Adam HPS, and MechT thought I should see more power and advised me it was missing some hp due to clogged cats that's why I had
Mcdonalds due the additional work below)Mcdonalds
removed the primary cats, and installed 200-300 cell racing cats very big job took a full day as they left the Primary cat shells in place and hollowed them out and welded a smaller straight pipe inside to keep resonance and hollow sound down, then they cut off the secondary cats and welded in the racing cats and relocated the o2 sensors to them.I was going to get it re-dynoed that day but as I said it took them all day and had no time for dyno.
Jim from
Mcdonalds said I should see at least 20-25 rwhp, from that exhaust workthe difference in sound & power on the drive home was very noticable.
HPS & I worked out are issues and I look fwd to working w/them again

I think this the 4th times you said you want to meet up and do our thing but the plan never come throught. So call me up when you actually there !!! I can only be there around 2 pm.
As for you getting the ECU upgrade on the 8th, it isn't gonna happen yet (at least on that day). I think you should verify your info to make sure so that you don't have to make two trips. Jim, is not the one calling the shot regarding to ECU upgrade. Just trying to help you here.

BTW, work described above is against federal, emission laws.
Please, no more fake dyno graphs or butt dynoes. Can we see a real, customer witnessed dyno graphs?

I'm w/you on the dyno thing I'll not be leaving w/out it...
The car doesn't need 4 cats, It will still be legal the car still has 2 cats on it....

So are you trying to say Every single 55 motor application w/HPS II is not making at least 400rwhp??
Does this include Fast55 Clk&SLK etc...
Why is this such a stretch? E55cent has the HPS gen I and he's fetching 360rwhp, So why in your opinon would a bigger blower more boost w/intercooler not be able to produce another 40rwhp?
There's obviously something majorly wrong w/blower itself a defective unit, I'm sure they'll swap it out for another and everything will be good..

HPS itself admits to it's own customers that it has not done proper tuning.
So how can there be 400 rwhp from their kit, if tuning has not been done.
The problem with HPS kit is, as has allways been - TUNING.
Or to be more precise, lack of it.
Giving customers fake dyno graphs is not going to get HPS cars to magically make power.
