Makes you wonder how the Mines R34 GTR is so responsive using 2530's on a 2.6ltr engine doesn't it?

 

Fact is - it's not.

 

Once it's on boost (4500rpm or so), the ONLY reason it rips through the gears, is because the diff ratios were changed.

 

 

Can't believe the last 6 pages, talk about rubbish...

Suppose we should not discuss or try to help someone who asks for advice or opinion with some innocent banter in between. Oh well sorry. Didn't mean to distress anyone. So where do you suggest we discuss different twin setups? Maybe a forum is not the place. Can you suggest anywhere else?

I know who guy who has done a heap of head work with his -5s and pushed a 474awkw With Dyno papers to show me when I was shocked... That thing is a rocket!!! He runs it 440awkw every day and only sets it at the highest when need to

I myself with all stock internals & -5s on 18psi running 330awkw

^^^ that's me mate :P

That's pretty funny !!

What would -9 s on e85 with forged internals, cams, exhaust be looking at reaching (power wise)

Probably max the efficiency of the -9s and maybe achieve around 370kw, if your setup is good enough

With the right setup you can achieve 330-350kw on 98

There's one bloke on here making 370kw on -7's so I'm sure you could get there on -9's with the right set up.

If I can make 325kw with standard actuators, AFM's and a shitty 3" exhaust I'm sure you could make a fair wack more with a decently set up car.

You really won't be able to screw enough boost into it to make a huge difference with the -9's. they just run out of puff.

This.

The -7s and -9s by 7500rpm are falling off and simply out of airflow, so you can't screw more boost in if they simply cannot supply the air needed.

Joy of having them come on so early, can't have it all!

You can make near enough the same on 98 as you can on E85 with -9s IMO, hence my earlier comment stands... Add to the fact there is not one person who's ever made legitimately more than that :thumbsup:

    • Hi GTSBoy, Excuse my ignorance but what does a "Bad" Knee point mean ? 
    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
