Precision Billet Turbos

[PJ.]

Thanks Matt, yours is a great result too.

It's track power only, 4th gear quarter throttle drag radial frying doesn't cut it in traffic.

[NYTSKY]

3 bar of boost will do that lol

[DVS JEZ]

Just got R34 on dyno with 5558. First few pulls setting afr's shows very good response. Havent turned boost control on yet

[34GeeTeeTee]

Can't wait to see results Jez

Just add ethanol already hehe

[DVS JEZ]

Left it for now. Was up too 262kw at 5500rpm 14.5psi. Was just having a play tonight and good to hear it running.

Waiting on the new fuel system to arrive so we're ready for the eflex.

Surge tank and lines are on the way after ur very helpful input Matt. Cheers for letting us know about urs.

Fark im so keen to get mine on the dyno now.

[scotty nm35]

Sif anyone takes a screenshot at 10psi, c'mon Jez, dont leave us hanging.

[DVS JEZ]

Hahaha. Just showing the progress. Still on 98pootane. Just running it out slowly. Have to say im very impressed with the response

[34GeeTeeTee]

No worries Jez, really looking forward to the results with this thing!!

Looks very similar to GT2871 results on a neo 25, I have a turbo that is highflowed with the same wheels that looks very similar to that graph though less power due to the restrictive rear housing.

Be interesting to see how well this turbo performs when you finish the tune! Neos always seem to give fantastic results.

Yeah.... Nah! It doesn't haha

Neo usually make a little less power actually because they are pingers

[Rolls]

The few tuners I talked to seemed to think they always made more power as they seem to rev more, seen two results that seem to point that way, eg matt from nistunes r34 that makes 310rwkw on a 0.63 gt3071r with poncams on only 18psi, dyno sheet is on here from a reputable dyno/tuner, and then mine which is a highflowed rb20 turbo with the rb20 rear housing still that makes ~258kw on only 16psi

On the same dyno for both?

Regardless from what i have seen, neo's seem to get a bit more compared to regular rb25det's with similar bolt ons.

[Rolls]

Yep both on same dyno same tuner. Pete from nistune and the morpowa dyno in adelaide, he told me every neo he has done has gotten fantastic results compared to the r33 engine, "chalk and cheese" were his words from tuning multiple neo and r33 motors.

I also had identical everything just changed from r33 rb25det to a neo rb25det with the r33 intake, all the same sensors, hoses, literally everything the same just the block changed and went from ~236kw at 18psi to 258kw at 16psi.

That's a solid improvement!

Is there any rewiring for sensors or the loom etc needed to put a neo rb25 in instead of an s2 33 rb25 or does just the ecu need to be changed?

The 34 looks like it will put up a good number, I think you'll shite 400kws in Jez

Im curious to see when this turbo maxes out.

I know Kurtis is now a power junkie but this thing is aimed at max response with strong top end. I have the goal set at 350+.

Time will tell with my one too. Its a 700hp turbo. But same again its main goal was response and 380+

[GTScotT]

Didnt powertune already push the stock bottom end SR over 400 with that turbo Jez? On E85

[Mitcho_7]

It's got decent response looking at that graph, especially for a turbo that size. That's probably partly due to the way it has been setup

He'll make it, i have faith! Its a 700hp turbo vs my 550hp turbo and i NEARLY made it, so you guys will make it for sure Cant wait to see, its sounding good!!!

[PJ.]

You'll close to 450kW at all four on yours Jez, if the bottom end will take it
