My brother just got his car back with a gtx3076. Made an impressive 261rwkw on 14psi. Rb25 neo

This is just a base tune and is being tuned on LPG + 18-19psi. Should see over 300rwkw easy

Whats it like response wise compared to the gt3076?

The GTX3584RS will support roughly 850-880HP on a 3.0L (maximum rpm of ~7500-8000) at a PR of about 3.1-3.3 No chance of getting 1000HP out of it, not unless it can be done at a PR of 2.75 and even th

It's the vapour injection system with just 6 injectors. But LPG injected are apparently pretty large and should be able to handle it (hopefully). I'll post up when it's done. Should he Friday

I was excited till I saw it was a dynojet dyno...

Realistic figure would be 10%ish less so 550ish, still impressive!

Wasn't your 410kw on a hub dyno? I could be wrong, but I had that in my head. I've never seen >600whp on a Dynojet from anything smaller than a GT3582R before.

You are correct, but I know it was inflated :) Hense why it only makes 360rwkw on a roller haha

There is no authority on whats high or not ;)

But yeah, DD seem to on average read a little lower than a Dynapack - so its fair to say its a solid 15-20% more power than yours... so its fair to say its a turbo which is theoretically capable of full boost by around 4000rpm on an RB25 and make near 420wkw on E85 on a Dyno Dynamics dyno?

This was with a .63a/r hotside, too....

Finally I got word the GTX3071 has arrived and will ship after Easter, They were going to send the Tial .82 with it but that is now out of stock even though I ordered it 2 months ago, not happy. It seems the only Tial housing they have left is the 1.06, is that going to cause me too much lag for a 2.5? I have a VQ35 im building up which would love the extra AR so im not too worried, just wondering if it will work well on the 2.5 for now or if its overkill?

with the torque converter your running Id imagine it will feel flat and lifeless down low and nothings gunna happen at all till you hit 4k, then all hell will break loose to the limiter and beyond :laugh:

I think 1.06 is too big for a 2.5L

I agree, the 4k stall will help. I will try it out, hopefully the flanges are the same and I can just order the .82 later, when it comes back in stock.

      NC MX5

      I know you don't want to hear this comment, but I can't not say it.  I just can't see 200kw being worth the time and effort. Its like guys with NA cars, putting in headers/exhaust/tune for a massive 20% jump in power. Great, the slow car is still slow and you're down $10,000.  My vote is leave it NA or price in a gearbox upgrade and shoot for at least 300KW, preferably 350KW+.  Now you have a NC that will try to kill you from time to time and will be exciting to drive

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      Ah yep. The main message I want to pass on is, try not to get scared of ghosts when thinking about knock/knock detection.  What I mean is, healthy engines make noise. Knock is also noise. Your knock sensor and ECU combo are trying to determine bad noise from good noise based on how loud the noise is. The factory knock sensors and ECU are not good at doing this.  Modern ECU's are pretty decent at it, however I'd still say that you would want to verify that if your ECU says it's knock, that you actually listen to it and confirm that it is correct.  Are you familiar with the plex knock monitor?  https://www.plex-tuning.com/products/plex-knock-monitor-v3/ I expect you're the type of person that would be very keen to play with something like this. It is great knock detection and you can pop some headphones on and listen to what's going on.  Knock that you've deliberately induced in low load low RPM areas is not really putting anything at risk and is a great tuning/learning/verification tool.  I just thought this was worth mentioning based on the way you were talking about setting up a base map and the Haltech base map settings. There are better ways to spend your time then chasing ghosts and worrying about detonation in scenarios that it is crazy unlikely to encounter it.  I was also wondering, what ECU are you planning to get? Will it be long til you pick it up?
