Hypergear Turbochargers and High flow Services Development thread


Recommended Posts

Stao just a question, given the hub dyno is only attached to the rear wheel wouldn't that make it rwkws ?, also next time you guys run it up would it be possible to do a run then reattach the front wheel and see if having spin up the extra weight of the front wheels makes any difference ?

Only if you think it can be done safely that is

Hi guys the cooler thats on it has a jap name but I'm sure its made in China. The one I'm using cost $195. Pm if any one needs one. My 600x300x68mm cooler is for sale also, did one dyno run only, $180.

This car its pretty much a rear wheel drive, front wheels only comes in for few secs, its not always on. Trent mentioned it picks up a tinny bit of extra torque with front drive shaft removed, and its not worth his efforts removing it. So all the runs done after the SL20.5 turbo has front wheels engaged.

I think my cooler is only a cheap one, had it for 6 years now I think. Have recently been thinking about upgrading but can only fit a 76mm cooler. Is a good quality 76mm fine Stao you think?

I have 3" cooler pipes everywhere so it gets plenty of flow to and from it. Just a bit worried about the cooler now

If you get a ARC you will be sweet, can't get any better and they know it

Like this, if it will fit a 33

further update on the GTR single setup. Now will be evaluating based on a custom trimmed SS3 compressor wheel. Hopping to reach 400rwkws mark with peek boost hit close to 4000RPM as possible. Results will be updated once tuner get back from holidays next years.

Tell the truth Johnny you just wanted GAAAAAAAATTTEEEE! :D

....... yes that is the truth :)

On another note, decided to strap my shit box to Powertune's heart breaker dyno.. only made 315kW... however I did notice my manifold was glowing red, meaning it needs MOAR timing :)

I logged all three runs too on my laptop and transposed that data into Virtual Dyno and used a lower reading "mustang dyno" setting and it was showing 345kW...

Another guy with a R34 GT-t said his car was making well over 360kW, and only put out 320kW.... so I'm pretty happy with my results overall considering it was all self tuned & self built.

I'll take a snap of my dyno sheet tonight for lulz.

So (again), I've decided to keep my car - this means more mods.

Nice result. What mods next? 150 shot on the stock motor? Haha

better intercooler, I found that my intake air temps shot up to 52 degrees towards the end of each run and subsequently the ECU was taking out 3 degrees of timing (I set it like that so I don't kapow motor)...

Turns out the HDi intercoolers are ok, but cooling wise they aren't that great when you're putting through 1.6bar of boost.. when I did logging on the streets with quick squirts in 2nd and 3rd gear intake temps were great, but the true test is when it's off it's chops in 4th on a dyno.

I'm seeing if it's worth getting a 100mm Plazmaman cooler OR just a ling long dim sim 600x300x100..

I would also be curious to know. Plazmaman items aren't cheap

When the car was on the dyno, I left the laptop logging data. Looks like the intercooler is unable to keep the charge temps low (I have a GM IAT sensor just after the FMIC).

I'm using a HDi core with Plazmaman "swept back" piping.. the FMIC measures 600x300x76mm.

P.S. I'll scan my dyno sheet tomorrow at work

    • Suspension Component Question Looking for some feedback based on people's experiences! I know this has been loosely covered in other threads but I can't find any direct answers/experience. I'm up for some bush/rod replacements and was interested in a hybrid approach between hardened rubber and pillowball kit. Why not choose one or the other? Well, this is for my daily driver, which I track once or twice a year. I like a stiff car and a sporty feel but I don't want to compromise the chassis too much with 100% pillowball gadgetry.  I know from experience and a tonne of reading that not all components affect ride quality in the same way - eg. in my case, coilover top mounts should be hardened rubber as pillowball transfers way too many undesirable qualities and doesn't have much more upside than a good hardened rubber. But, pillowball tension rods translate to much better turn-in/steering response and make the car significantly sharper, without negatively impacting ride quality in a significant way.  I'm not TOO bothered by NVH (to a degree). So, with context out of the way, does anyone have any experience with a hybrid approach as mentioned above? I'm going to replace all components over time so am seeking guidance on: - front tension rods - upper camber arms - rear lower control arm - rear traction rod - rear upper camber arm Secondly, is there any reason why this is a bad idea? Or any other info/wisdom that I might not be considering. Cheers 🫶
    • That's good to hear I'll stick with the stock I hear they are good for 500hp and I'm only shooting for 350-400 once I can get this thing sorted and get to actually building it. 
    • The stock one will outperform any aftermarket standard position exhaust manifold. If you don't believe me, do a back to back test (same turbo, same boost, same timing) and you'll be super surprised.
    • Any recommendations on a decent replacement manifold that doesnt break the bank or require additional mods for the stock turbo setup? I figure if I'm going to pull the manifold off anyway to fix the studs might as well replace it. 
    • So I checked the turbo out today. Very minimum play at all just enough for the oil to take up when it's running. I did find an exhaust leak at the manifold. 1 stud all the way in the front is missing and the one all the way in the back is broken off. Front has visible signs of an exhaust leak. I'll fix that soon but that's not my problem still.  I also found that the nipple coming off the turbo had the hose capped off and a hose ran from the j-pipe by the bov going to the wastegate. I removed that hose and capped that nipple and put the turbo nipple hose back on the wastegate.  There was a ton of oil residue all through the charge side of the intercooler piping going to the throttle bodg. I'm thinking that's from the pcv. Doesn't seem to be coming from the turbo that was all clean on the pipes side.  Haven't had a chance to check fuel pressure yet, haven't had time been having to pull a lot of doubles at work. I did pick up some carb cleaner to clean the iacv but wanted to make sure I had a fresh gasket in case the old one rips when I pull it off.  I'm waiting on a MAF that was supposed to be here today but delayed to Monday. Have a double Monday and Friday and work all of next weekend so going to try to find some time in the middle of the week to try that out. Did about a 10m trip around the block today and towards the end the issues were coming back. Fingers crossed on this MAF but if not just going to throw a fuel pressure gauge in and see where I'm at.  Did notice today that I can definitely hear the injectors pulsing. Very audible clicking coming from them. Assuming that's normal? Should also mean CAS is functioning somewhat properly. After it warmed up when I started it the intermittent misfires came in again. Did start doing that before it was fully warmed up.
