This is by no means a advertisement for hypergear (we do ALOT of product development for different companies), i just feel the result is quite impressive... and it has fuelled me to get involved with thier RB25 high flow and bolt on turbo. Which i hope to test in the new year.

What impressed me the most was torque, it is very rare for me to see a 4cyl make over 420nm so when this pulled over 500nm i was floored... especially as it is on a CA18DET (if you look at the final graph i have overlayed it with a RB25DET with HKS GT-RS...

I attached the graphs of the testing, each run was tuned to suit. Startting at 18psi and working up until peak efficiency (25psi) we found at 26 psi it flattened off.

Bear in mind these are all done with the std internal wastegate and a turbosmart tee, so ever so slightly better results would be reached with an ebc (small drop in boost with the tee... only bout 1- 2psi)

For those about to tout the the dynapck power differrence thing... we anticipated it and ran it on DR DRIFTS dyno (MAINLINE) first where it pulled just over 240rwkw, on the first tuned run here it pulled within 1 or 2rwkw (see red line)

results 281rwkw and 502nm out of a built but stock headed CA18DET.

another interesting post!

got any pics or prices of this product?

Nah i dont sorry.

but here is the website http://www.digi-hardware.com/

i reckon this turbo on a SR20 would be sweet, this turbo may also be available in a 0.82 to suit RB25 which i would also be keen to test....

The hard part is finding cars to do the testing on, i dont use customers as guinea cops, and will only use proven products. Tao has bought a R33 which ready for testing in january so i cant wait.

nice. :blush:

put one on your old silvia trent. I'll let you borrow it :bunny:. can do a comparison to the T517Z that's on it now.

it's certainly making pretty handy power out of a CA18. 150kw at 4,500 rpm is not bad at all for a turbo making 280kw on a 1,8L.

my god there is a lot of negative people on nissansilvia. 90% of the people who looked at that blokes graph found something negative to say about it. geez, be happy for the bloke.

I would be glad to help Hypergear out by letting them give me a turbo and plenum :(

I was walking around the show looking at all the high HP cars and noticied that EVERY SINGLE ONE runs a hypergear plenum...

and then DiRTgarage rubbed one in my face as he left ;)

i believe wytsky has the TR43 on his car trent, possibly speak to him about it and im sure he did post a thread up not long ago.

yep, but dont be disheartend by my results, i had the discussion about it because the kw seemed a bit low, but from what Sam and I have come up with, a slight missfire (that was getting worse) and the fact that his dyno had a stuffed weather machine meant it could not correct my results on a 32 degree day are pretty much the answer because the car feels great now, but according to my previous graph I had 230rwkw and now only 215rwkw...

I will post up my new results after I have time to fix up the missfire issue and Sam sorts out his dyno.

btw, on my previous tune ( that I know for a fact was less powerful then my current one just by the feel) I had 230rwkw and around 640-650nm of torque.

hahaha ns.com has the lowest combined iq of any forum.... just take a look at the drift section.... it is ruled by pubesent SA wanna be's.... i know i used to live there....

you rang? ;)

that turbo, that wouldn't be the one i'd be looking at would it? i'd be after the hi-flow option?

i don't really know much about reading those graphs, but is the GTRS a lot more responsive down low? or is the actual road difference not that much?

Yes, but don't forget RB25det's got 2x more cyclinders and 0.7L of more capacity. This on RB25 should make even more power, Torque with heaps more response. 260RWKWs at 5000RPM on a CA, its some thing i've never seen before.

lol, I think you may have hypergear and hypertune mixed into one. they are 2 different companies. :(

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
