As part of the final stage of development on the Turbonoz Z32, still on stock Auto turbos & injectors but with a Nismo adjustable FPR:

 

447.6bhp & 462.1lbft Flywheel

389.2whp & 420.1lbft Wheels

 

Still on 2" IC pipework, stock turbo elbows & manifolds.

 

At the dyno now, will update if it goes higher. Turbos have nothing left to give: Peaking to 1.45 bar and holding 1.2 bar to the redline. Lots of fuelling left, solid as a rock & very repeatable.

 

Might upgrade the FMIC & pipework, otherwise this is it until larger injectors & turbos.

 

For information: my last 1/4 mile run of 12.74@111mph was done at 415.4bhp.

 

FINAL RESULT FOR NOW:

456.5 bhp & 481.2 lb·ft (Flywheel)

397.0 whp & 437.5 lb·ft (Wheels)

Nice results there matey, whats the cycle like on those injectors lol

Cool

thats quit a large transmission loss 73hp

but good result anyways :)

Filthy autos for you.

 

Well, I think the potential is fully realised in its current spec. Nothing more to give.

 

Edit: 58.4bhp transmission losses.

Now that would be telling. Suffice to say I had to pull a huge amount of fuel from the 415bhp map.

does this effect the reliability of the injector it running at higher than stock pressures and being worked so hard?

Cool - nice one Noz...!!

What's the engine specs?

stock.

I've pushed injectors a lot harder than this over the years on other vehicles. I've never had one overheat & fail.

 

By increasing the base pressure, it's actually the pump that gets worked harder. The injectors still open for the same amount of time, but more fuel flows through them for the same duration. There's a lot more headroom than I imagined there would be. The bottleneck is the miniscule turbos.

Persistence pays pays off.

 

455.0bhp & 464.9lbft Flywheel

395whp & 422lbft Wheels

Nice work, the stock fuel pump can flow a lot so you'll be ok :)

Fook me I'm getting proper excited now.

 

Does the mpg change at all?

Z power

well done Noz

Great work Noz :bow:

Oh right im only asking for my thrist for knowledge, also reply to my pm eill ya :)

sorry nos .. for some reason i looked at your fly torq and then wheel hp lol ..

 

Car-Mad ... yes and no depends on how you drive it ... any car thats mapped for more power to a point can be better at mpg but this all depends on your foot

soon as you start to use all the horses more fuel it will use

Noz mapped mine and now mpg is better cause most z's overfuel, mine is perfect now!

Oh right im only asking for my thrist for knowledge, also reply to my pm eill ya :)

 

Of course mate, didn't mean my answer to sound curt at all.

 

I've not got a PM from you though!

Odd could od swore I sent it

Great effort mate, is it a stock intercooler setup as well I couldn't find the old thread with more info?

Final results of the day:

456.5 bhp & 481.2 lb·ft (Flywheel)

397.0 whp & 437.5 lb·ft (Wheels)

 

I think there is potential for more, truth be told my aim was 470 on pump fuel, so I was 13.5 bhp below my target. I've completely rewritten the fuel map from last weekend's drag effort, and it drives a whole lot nicer for it.

 

I'm going to try a different fuel (these runs were done on Momentum99), and obviously an upgrade to 2.5" pipework plus a total rethink on the generic FMIC would be ideal.

 

19 power runs, about 25 pulls in total.

Cheers mate. Generic FMIC with paltry 2" pipework.

Cool so are you running the twin short intakes where the side mounts normally locate or the stock single MAF?

Dual short intakes with the MAF relocated into the engine bay. Suffice to say, even that hasn't stopped air being forced up the filter causing a rich mixture at speed. I have no fog lights or rain guards, so I'll have to re-block the holes in the bumper. Annoying!

wow, even with bigger turbos my TT didn't get power like that,

 

what do you think you could do with an NA? :wink: lol
