Hey flo .. Sorry to hear that it's leaking... Where is the fluid coming from? On mine I traced it back to the reservoir .. My friend over filled it thus caused it to overflow. At first it looked like the sc but it wasn't .. After I took out some fluid it ran fine.. Also check your lines just to make sure it's correct..gearhinz has the fluid and so does gtm.. In case u need to order more..

 

Ok it's leaking from either this hole(I have no idea why it's there) or a what looks to be a crack to the right of the hole:





It has fluid residue in both crevices so I have no idea whats up, Danny had to clock the blower to fit into place and seeing him work... I know he wasn't the culprit. GearHienz has stepped up with some serious HKS support during my ordeal and the end result is to send the HKS unit back to HKS Japan with an open ended return date. I've put serious time, money, and aggravation into this project and would love it see it running before I leave for work again in February(8month deployment... FML) so the Rotrex is going back in. The old Rotrex unit turned out to be good, only ONE person in the US does any work on them:

http://www.superchargerrebuild.com/?page_id=69

His name is Todd and he's a very very professional guy, he could've easily charged me for a complete rebuild but only did a inspection and reinstall a 90mm pulley to finish it up. He reported no problems with the unit and it was good to go, I had the unit shipped next day to me. When I got it back, it felt 1,000,000x's better and had no wobble whatsoever. He told me the unit's are very sensitive to pulley placement which seems to be a reoccurring thing on these blowers. Rotrex's have better support and the fluid is less than the HKS', though the unit's may look alike externally.... holy cow are they very different.

The car was at HP Logic and it put down some pretty dismal numbers in spite of my supporting mods, the tuner didn't set up the chart correctly so the dyno sheet looks a little weird and lacks some info. We've spoken and they've agreed to allow me to bring the car back on the dyno until I'm happy at a discount so they've certainly earned some respect in my book. However, the MAF was maxing out voltage wise at about 4800rpm and was logging 5.08v. If this is what the MAF is reading... 6.8psi may or may not be completely accurate. After a frantic phone call to Sam@GTM, he said that 6.8psi is too low for the HKSGT7404(it has a GTM 90mm pulley) and there has to be something else wrong with the unit. All in all... 290whp/256wtq would equate to 330whp on any other dyno that's not a Mustang. I'm still looking for about 355-365whp/340wtq with my new set up.

Moving forward to the Rotrex install, Jas@JDSMotoring has really helped me with this project and sent me a Uprev GT MAF next day via Fedex. A 3" Intake pipe which relocates the MAF on the 45 degree elbow entering the TB could've very well solved my problem but the MAF was easier to be had with my time constraints. A 90mm pulley has been installed on the Rotrex unit so I should be seeing about 7-8psi and everything should be a ironed out in regards to a known good(non leaking) unit and a solid tune.

Cliffs:

-Blower peaked at 6.8psi w/90mm pulley
-MAF was maxed... 5.08v @4800rpm
-HKS unit was leaking fluid and going back to HKS
-Rotrex going back in

I'll include Cliffs on the first page on eventful posts on the first page once the build is completed.

 

joel keep your head up buddy, everything will workout for you.

 

Thanks D, it'd a good thing Danny is thorough because organization and resourcefulness Has helped this build.

 

Man sorry to hear about all your troubles, hope everything works out for you before you leave.

 

Looks like its going to work, your build looks nice and I'm going to be paying very close attention to your progress.

 

I find this being the best HKS SC post thus decided to post it here.

I have a stock HKS SC (NOT GTM modified) fitted with GTM Power Package (Extended Cold Air Intake & 90mm Pulley).

I got it tuned on a different dyno thus I am unable to compare the power difference.

I doesn't seem to be making more power...only seem to be bringing forward the boost (comes and speak in lower rpm). The boost seem to be almost same (0.5 bar on my Defi) if not lesser.

Shouldn't the 90MM pulley increase the boost by 1-2 PSI?

 

Mine is at about 0.55-.6bar (according to my Defi ). I'm using the C30 Rotrex blower and it made 360whp on a DynoJet before I installed it(I bought it used), I made 295whp on a Mustang and I've read it's about 25%-30% difference between the two dynos. I was aiming at 370whp and if you add 25% to my 295whp... I'm right at 368 which is great and exactly what I was looking for.

To answer your question... Are you data logging anything? I've seen mine go past .5bar as a passenger but really don't look at it when I drive. I opted not to use the Replay comtrols on my defi set up simply becuase of space and I dont want a bunch of things cluttering up the waterfall. The guy I bought mine from used meth on a 95mm pulley set up to make the 360whp. The cold air set up helps but I have a Varis bumper scoop that sits right in front of my HKS mushroom filter.

 

Sorry to hear about your problems. Best of luck with the build! Can't wait to see the final results

 

I put the Rotrex back in... I'm going to post my updates.

 

i can tell you right now, mustang dynos are nowhere near 25-30% lower than a DJ. Infact most are calibrated to dynojet offsets. Otherwise they closely mimic dynodynamics and about 10% difference

If you are making 330 on a DJ, that would be lucky

 

I think I used the wrong dyno brand for the 25-30% differential... DynoPak maybe? If I made 330whp on a HKS it would be the worst HP numbers for this kit in it's history. I'll be making an appointment to run the car on a DynoJet/Pack(not sure which one it is). Here are the various dyno's that this kit has seen. He never changed the pulley on the meth run and only had an exhaust/no cats, 440's, and a Emanage.

The first attached dyno is a comparison from my last dyno... pretty much HKS GT7404(Dotted line) vs Rotrex C30-94(Solid line). The second attachment is the first run solely on the HKS GT7404 and the last one is the dyno run on the kit from it's original owner on meth, however the vid is without meth but at 5.5psi(95mm pulley). My set up is about the same minus the pulley upgrade which is 90mm(7.8ish psi) and I have:

XYZ Resonated Y-pipe
ART Pipes
MREV 2 lower plenum

You very well may be right about the 330whp but I don't believe it and I won't until I do a dyno run other than the Mustang.

 

i'm just sayin. i've been on mustang dyno at sound performance, dyno dynamics at forged and local dynojets.

I have yet to see anything more than 15% different.

Regardless, as long as its fun, dyno numbers are nothing more than a tuning tool. Plus its better to be underrated than overrated.

Good luck on the dynojet

 

Well...I know that everything is relative, including dynos and boost psi, but if you're only generating 5.5psi then that's what the problem is. I'm not sure why your kit is only generating that boost; I know the HKS kits are capable of more than that...on typical Vortech kits with the stock pulley they will generate 360~380whp on approx 7~9 psi of boost...

 

I have a 90mm pulley.

 

I am recording 0.5 bar on both my 90mm and 95mm pulley. Is that correct? Hhhmmm, I am going back to the dyno I used for stock 95mm pulley this weekend. This is to see if the 90mm pulley made any higher boost/whp. However I am pretty sure the powerband changed.

248 is getting very very hot for oil.
your cooler needs better airflow.

 

A few runs then the horses seem to have escaped...
Highest intake temp?
