Clearly people in Sydney have forgotten that the GT-R is designed for racetracks, not mind numbing bafoon I mean drag racing

Don't mean to be direspectful but Trap Speed is used as a tuning tool. Nothing to do being a bafoon just more to do with verifying dyno figures, as a graph can say what it wants but Mph is the purest number for measuring peak power.

So if a dyno sheet quotes 500kws peak power and the car pulls 130 mph then questions need to be asked to the validity of the power figure quoted on the dyno sheet.

Like it or not its just the way it is.

i agree with this..... even though it is my own car....

on 500kw i should have gotten 140mph or very close to it....

Always had a suspicion JEM's dyno reads a little happy but I know Adam is a good tuner so I went to him for his capability rather than what his dyno will spit out.

Next time around I'm going to make sure I'm getting 31psi on the night so we'll see its real MPH :)

So ... youre saying GTRs at WSID go there for more than just being kicked off after the first run, and refusing to install a cage or parachute?

I thought you never get to run at WSID with all the VLs dumping their guts every 5 minutes

Speaking of stupidly high reading dynos, what happened to that bloke that made 700kw with -5s. He seemed to disappear after running his car on an Aussie dyno

Ha ha. That thread was the definition of insanity.

Has anyone considered twin 7163's as shown here?: 

http://www.full-race.com/store/efr-turbo-kit/nissan-rb26dett-efr-twin-turbo-kit-1.html

This looks to be the direction I will head over the winter. 

Have seen a few different twin EFRs used on YouTube, up to 9180s.

What I did think about, if you ever got defected for having a single on,  could you go with smallish twin EFRs legally ??

Would think the cost of going back to twins would be pretty prohibitive .

Here is an RB26 @ 800awhp + with twin 6258s

Twin EFR's look just as out of place as one larger single. 

Twin EFR's don't mount in the factory position.

I'm from the states so I don't think legality is really a big issue here.

Positioning isn't really important nor is aesthetics, for me personally. I'm looking at performance from twin 7163's versus other options, like a single EFR. According to Jon@FullRace, these turbos will be enough for 700whp on 91 octane, which were my goals originally. I don't mind the twin setup if it performs as well or better than an EFR single for the power requirements.

Go for it but let us know.

That 800awhp is on the high side but it is on the dynojet I guess, 80hp lost is on the low side that's for sure.

^^^Correct! This is what these turbos are about! 99% of people arent going to buy an EFR for the drag strip!   These things are all about on/off throttle type of stuff and the widest power/torque band you can just about have "in a turbo car"

thanks.  i get tired of posting this ^^^ in response to "what does it trap" posts.  Believe me guys, i get it - you want to compare it to every other turbo out there.  The thing is, these are different.  And the difference is not on a dyno or a drag strip.  If you actually get real experience with an EFR then you will get it too.. and if drag racing is your thing, Twin-EFR is the way.  Not single.

    • What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.
    • Easiest way to know is to break out the multimeter and measure it when cold, then measure all the resistances again once it gets hot enough to misfire. Both the original ignitor and the J Replace version. Factory service manual will have the spec for the terminal measurements.
