great work thankyou intresting to see the numbers... will read them carefully

only thing is my figures at 4wkw not rwkw.

and yes stock gearbox and diffs etc, and yes those tire specs. i also launch at 6500-7000rpm

:angry:

hmm.. seems the t04r makes less power... but with less response going by 32-gts's results with the t04z

dyno

interesting comparo's... normally youd think the car with lesser power would be more responsive!

just having a a look at that thread very nice. very nice results indeed well done to him, obviously its a better setup no point comparing.

bigger cams than me, better turbo.

0.81 exh does he have, mine is bigger 0.96 which means more top end and less response.

we have our cams set to 0 so havent dialled in any extra midd response yet.

Also hes running 24psi and im running 18psi

i have no excuses thats obviously a better set up, cant argue that.

im very proud of my results for what we have and what we have done.

all not comparable if you ask me...

:)

how much peak was made on 18psi? 415kw = 556hp at 4 wheels for me

i need more boost and rasie revs to 9000rpm

thanks

have you had a look at your cam timing and cam choices as there is something not quiet right here as the lack of mid range is remarkable

you have gain good top end hp dont get me wrong but i honest think there is a lot more you could get out of this combo around the 5000rpm range ie i know of a twin t04z hks rb that makes more power at 5000 than this sheet and that should not be the case. And gts32 is making 2.5 times more power at 5000rpm thats not just a slightly better turbo.

again great result but i would revisit you cam timing and cams you could build a really monster with the right combo

yep no worries

well this is only the first effort on bp ultimate, i'll be talking to the tuner and see what we can/have tried with cam timing...

like i say i know on paper it doesnt look so good, but as far as im concerned through gear changes it comes back to 5500rpm and its on boost it picks up and goes... so its okay.

mick

first place to start i would try advancing the inlet cam maybe 4deg first go and what you should see is it ramp up the same but just 100 or 200 rpm earlier with next to no change to out right hp, and i have mine as high as 10 deg advanced. The exhaust tends to effort mostly out right hp with only small changes to low down power i found running a couple of deg advance gave good reason 2deg gave 30rwhp BUT this will be different for every combo etc so try a couple advanced then a couple retard and the results will speak for themselves. The only pain is changing the exhaust is slow and everything you touch is hot and you have to reset the time each time.

out of interest what cams are you running?

pete

ps best of luck

bigger cams than me, better turbo.

0.81 exh does he have, mine is bigger 0.96 which means more top end and less response.

we have our cams set to 0 so havent dialled in any extra midd response yet.

Also hes running 24psi and im running 18psi

housing size isnt going to make upwards of 1000rpm difference though

And as for the amount of PSI, more boost isnt going to make it more responsive.

i wasnt really referring to your end power, which really is quite good, punching out over 400 is no easy feat, nor is it cheap. Top effort indeed!

Its more the mid, and the time that it takes to get there before around 6200 where you start to make good power

You have cams, and headwork as you've stated. So your not gonna be "that" far behind. All things will make a difference between the two packages without a doubt, but how much?

It'll be good to see what comes of more R&D with your setup thats for sure.

Its all about time and fiddling :)

yeah no worries

defo look slike it needs more power midrange for sure.

will see where it takes us...

but i am reasonably satisfied with how it drives. i will take it to the drags and see how we go.

i do think i need a 9000rpm limiter tho.

michael

Here is another with 1.3bar (18psi) of boost and a Garrett T04Z on a built motor.

Very similar to R32-GTS except he has more top end then I do. These Garretts are a great Turbo! :) Love to get to 600HP though!!

Maybe at Willowbank one day :)

Nice result anyway, wasn't having a go at you just wanted to show the same turbo but at the same boost setting as yourself.

It's not easy cracking the 400kw mark so well done. I want 450kw just like R32-GTS!!!! More boost I hear :)

ah lol

yeah i know dude.

t04z kills the t04r. i have seen t04r and t04z dyno sheets many times before. the mid range of t04z is immenlsey superior to t04r.

to4r always look like mine, and t04z look like yours.

but no serious, i'll be at willowbank racing mine, would love nothing better than to line up against a car like yours.

thanks

michael

Congrats Mick,I have no doubt you will crack a 10.The ONLY place your car MIGHT get shown up is on the street on a short squirt.You have a great combo to achieve your desired result....to run a 10 on radials,good luck.

Hi all,

well ive seen a few threads of the type recently, so thought i might post one up also for those intrested.

R32 GTR tunning a HKS T04R with a 0.96 exh 18psi.

415kw at 4 wheels

Will be out at willowbank as soon as i can hunting to flog my current pb.

    • 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.
