Rb30 Hybrid Upgrade, All Dyno Results

Recommended Posts

Yeah Matt , end of the day it's what you want from your car. It's all fun but an expensive exercise
Here is the latest Dyno , bit hard to compare because you need same scaling setup on the printout to compare BUT it drives better.
As you can see it is hitting 24 psi and dropped off a little mid range but will be tuned again after some Klms have been clocked and a bit more boost added
Having trouble downloading Dyno ?
 
Your R34 has all bases covered, more than enough top end power and bulk torque everywhere. I love it.

Yes it most certainly is expensive. My OCD kicks in and I want everything to look as good as it performs which means, billet bespoke covers, fancy fasteners, new or near new this and that and before long I've doubled the cost of the original modification.

Nice result! No doubt there is more to come.

Hey guys. Im trying to find info on r33 s1 head on rb30 bottom end regarding vct. Im looking to see if someone has a graph to compare vct on vs vct off on there dyno graph. I have recently changed from the r32 s0 rb25 head to the r33 s1 vct head and wanting a graph to see if its worth me changing exhaust housing etc. Thank you.

Mine is a series 1 RB25DET head on an RB30 bottom end, NVCS on - see above. No dyno runs with it switched off... but I wouldn't ditch it unless I was aiming for big RPM and all top end power with a big turbo (1200+hp territory).

When you had it on the dyno did you guys mess around with different times of when it came on amd turned off etc to get the mid range up etc?

Not yet, but that's the plan.

Nice. From the info iv been told its around the 500-600rpm better which is what im aiming for over the last setup and with fixing the wastegate issue im hoping to be around the 40-50kw mark better in mid range.

You want it on asap to create more torque, and off when you reach peak torque.

There's no "playing around" with it, as it's not adjustable. Just do 2x runs and find where the torque intersects and you'll know fast enough where to switch off VCT.

Didn't go for the fancy gear, getting the car going hard is expensive enough LOL , but I love a nice looking motor, your cars engine bay looks amazing , it's done right and I would love to have it, a little jealous LOL

Had the first chance for a bit of a run this morning , the car drives better than the Dyno indicates  , it is better from the moment you press the peddle from what it was. Looking at the 2 dynos Graphs the old tune looks better under 3850rpm but I can assure it doesn't drive better. Should be interesting to see how it goes with a little more boost when they do the touch up tune , I don't expect much, if any improvement under 3000 but it is already coming on at 3000 ish pretty hard and impressive up from there. Good streetable ride and a shatload of fun.

Here is Pauls impression below of how the car is running now after a fair test run , around 120 Klms

Booked in for Thursday for the final tune

Here is the run-in tune , going down later this month to finish it. thought I would post it and see if there will be much of a difference after the next tune . Do not expect much of a change , just a bit more .

  The results were emailed to me and I was not too happy when I compared the both Dyno runs , but  the scaling was different for this tune. But the car runs better everywhere than the Dyno suggests. Need your bum in the seat to appreciate it.

Paul was up last week and took it for a drive , well more like a 120Klm romp, blew 3/4 of a tank and he was reasonably impressed with the way the car runs now

I drove this peach a couple weeks ago while up holidaying in Pete's home town.

Pete has mentioned that the old and new graphs don't show much difference. Throw the sheet in the bin is all I can say. It was stonking before this round but its halarious now. 

Doing the 120 km belt through "The Lakes Way" which is Pete's little playground was interesting. There is not a corner in the whole joint that you need 1st, 2nd or 3rd gear. There was a sign posted corner that was 35 kph that I did in 4th gear. just as I straightened the wheel it was turning tyres. You honestly couldn't fall off song in this thing if you tried. A choice of 3 gears in every corner. Use odd gears or even gears.

Anything from 3000 RPM and its ON. Not just 'coming on"... full noise, MFD blinking red shit. Being in such a tall gear all the time you need to recalibrate. 3000 RPM in 4th and feed it on, you think you're ready to change gear, look down and you're at 5500 RPM. In 6th, it has 24 psi by 2700 RPM. It’s a joke. As a street GTR, it would be bloody hard to beat this thing. Can turn tyres in the first 4 gears without much effort at all. Tyres are not motorway spec junk either. 275 RS4's with a Quaife front diff and the transfer case mod done.

If you're not happy with it Pete, time to sell it because it does its thing so bloody well!

You could quite easily get away with a 9180 on it and still be sweet. I know we have both spoken about it a zillion times, it aint for you. 

It does need brakes though. The thing doesn't stop AT ALL! Perhaps a set of decent pads (Endless CC-RG's) would go a long way here. 

The torque steer might need to be addressed too. It's quite scary.

Here is to the tadpole. The black tractor of the Mid North Coast!

Pete, congratulations mate, what a beast! You don't need the fancy gear when you have bulk power and torque on tap from 3000rpm! It's my turn to be a little jealous :50_open_mouth:

Well , had the tyres refilled with Nos for free at Jax :) they averaged 30psi , so I cannot say what pressure was in what tyre . the car was in the shop for 4 months and it was a bit slack at checking the pressure when I got it back , so all pumped to 38psi, gave it a run and it goes straight , torque steer eliminated, takes a bit of the excitement out of it , LOL

Just rolled out 467rwhp with 17psi 11deg of timing @6300rpm.

Had trigger problems from factory cas.

Ordered a new trigger kit from NZ Wiring and will be going back on dyno on Friday. 

Shitloads left in it.

Nice work, I know this thread isn't for discussion but you left info on what turbo you used out which is one of the most critical bits of info?

Finally had my r33 on rollers again. 2 years ago dynoed 440 hp @ 1.6 bar of boost (328kw @ 23psi) with what turned out to be a significant boost leak (vacuum nipple on/under throttle body wasnt blocked).

 

Anyway now with the boost leak sorted (and new bypass etc) I hit 553 hp and 725nm at 1.55 bar (412 kW @22.5 psi)! Over 100 more hp with less boost! Wohoo

 

4 years ago when I started designing my setup my goal was a responsive 500-550hp so Im super happy default_smile.png&key=f90b0234b42e52fa3ae1435b0b09055f5661a708bafba83253fd73a7a57a4868 hits full boost somewhere around 3500 rpm from what i can tell while driving.

 

Rb25/30 (refreshed bottom by garage-d)

Athena head gasket

Arp bolts

Reimax gears on stock pump

Baffled sump

oil cooler with thermostatic plate, filter recolation

Holset He351w 14 cm with iwg welded shut

Turbosmart progate 50

Sinco twin scroll manifold

Freddy intake with stock throttle body

3,5" exhaust (wg joins exhaust after downpipe)

600x300x80 mishimoto intercooler

VAG coils

1100 asnu injectors

450 walbro

Gfb 33mm bypass

Pmas hpx n1 MAF in 3" intake Pipe

Nistune

Gfb ge-force 2 ebc

98 pump Fuel

 

Im sure Im forgetting alot. Was running into some issues with the ebc not reacting very well to duty changes (0 duty cycle gave 1 bar and 100 got us 1.05 bar). Had to install a restrictor before ebc solenoid and even with that now running 99 duty cycle. Well, it works and I dont think any more boost wouldve helped. And with stock pistons/rods it better to be on the safe side.
