So you're saying a car doing a 1.5 60ft time will have the same mph as a car with a 2.2 60ft time?? I dont think so.

60 footers are only an indication on how well your car hooks up and leaves the hole. Doesnt have anything to do with power.

Is it being implied that a bad 60ft will result in higher or lower trap speed?

Also, not hating, but can anyone explain the allure to owning the most powerful anything, anywhere? Would just like to know the motive behind it, as its quite different from the fastest etc.

Or is this more so the car is being built to a purpose and it just might happen to also be the most power, which is a lot more reasonable in my mind.. But building a motor to simply have it be the most powerful I can't understand.

Wtf now that rb25 make no power comment is there lol I looked twice it was gone before! Well im here to prove you haters wrong

Haha, sorry you thought it was hate, all cos I left out the smiley face. I thought it was pretty obviously sarcastic considering that this is a skyline forum! Sorry for the confusion.

Are you planning on putting your car down the strip?

It is the most powerful RB25 in the world, but isn't Australia based so not so relevant. The one in the UK from a few years ago was also up there in power

Always lower. BUT if the car has huge amounts of power it will still post up a good mph. as stated 60 footers show how good a car hooks up and well the driver can drive the thing out of the hole.

The car was built to be a bit of everything. Certainly not max power. But that comes as a bonus. As I am not going to go down the drag only route I dont really care for times. I will take it down to see what it runs but im not going overboard on trying to run crazy times.

Also im not here to argue about what 60ft times mean and how they affect mph. Though I will say, having a slower 60ft time essentially determines where your run starts from. So it will affect your top end mph. An auto set up on slicks will not run same mph as a manual on street tyres, ive seen it happen. Anyway back on topic, I just wanted to see where my 25 stood against others that have been built in aus.

Rb25s dont make power?? Lol ok

My car might be back on dyno this week

So you're saying a car doing a 1.5 60ft time will have the same mph as a car with a 2.2 60ft time?? I dont think so.

You have much to learn grasshopper.

Lol dude ive personally ran identical runs but different 60ft times and the mph can vary 2 or 3mph. Thats a shit 118 run. Take that up to 140mph and the difference will be over 5mph. Explain to me how a car slipping and sliding thru 1st and second can possibly get the same top speed over a given distance compared to a car that just grips up and goes?? Im curious to hear your answer.

You are just dragging your own topic off topic, there are too many variables to consider and you will most definitely not be the only person here who has done enough drag racing to form opinions on patterns - it'll just turn into a flamefest. For what it's worth I've run everywhere from 12.6 to 13.5 with 1.9 to 2.5s 60ft times and trapped between 110-112mph for practically all of them (and launch was not the only thing that changed - tyre pressure, cleanness of gear shifts etc all were tested or perhaps not done as well as possible every time), I tended to see a bigger difference in trap speed when I missed a gear or hit a limiter than on a bad 60ft. Not saying this will be the same for everyone, just saying it's part of my experience.

Here are a couple of time slip break downs from past runs from my car - two completely different events, I was ALWAYS in that speed range. Different tyres for the 12.6, same power.

0-60 Foot ET: 2.247
1/8 Mile ET: 8.849
1/8 Mile MPH: 87.240
1/4 Mile ET: 13.330
1/4 Mile MPH: 111.580
0-60 Foot ET: 1.906
1/8 Mile ET: 8.186
1/8 Mile MPH: 88.880
1/4 Mile ET: 12.634
1/4 Mile MPH: 111.300
I am sure with 600kw things might change a bit of course haha

Well I did say im not here to argue the point but if it keeps getting brought up im all for hearing others opinions. Got a touch up tune on the 33 last night, cold ambient temps but on 24psi highest intake temp was 31deg! Awesome results for the new cooler. Will have it on dyno soon to see exactly what the difference is and also to wind the boost up.

Yep, thought it'd be worth seeing that to ponder on if nothing else - they're all on dragtimes.com for an R33 GTS25t Skyline, I put them in there years ago so I haven't just filtered out ones to prove a point.

Anyway yes - dyno results sound like a good thing, is it going on today? And how high was it getting before? Good luck, again :)

    • This sounds like a perfect excuse to install a Haltech R3.
    • I do believe from context he is talking about a S0/S1 R33 RB25 with associated ECU and Wiring for that, and a manual gearbox into a R34 N/A Auto. I don't have the knowledge of all the pinouts and such but my gut feeling from doing my own conversion is to use as much of the R33 stuff that you can. The "car" wiring is quite seperate from the "Engine" wiring when all things are considered. The only things to truly consider 99% of the time is the cluster, reverse lights and potentially disabling the 'not in P/N' immobilizer circuit.
    • A realistic expectattion of how long it has to last also comes down to.... when do you think you will be banned from registering and driving old petrol powered shitters? It's 27 years since that thing was built. It probably rusted out 15 years ago. It was probably repaired and looked OK for another 10. If you do a similarish bodge job now, or perhaps slightly better with some actual rust conversion and glassing, then.... get another 10-15 years out of it, after which you'll only be permitted by the CCP to drive electric cars manufactured in their Shenzen zone anyway. 
    • Let me assume that the concern over a manual ECU is that the NeoDET that you have was an auto and has an auto ECU. That ECU will not be a problem, but you WILL have to Nistune it. And you would have to Nistune it even if you had a manual ECU, because the turbo ECUs will shit the bed if they do not have all the things that they were told they have to have, to be happy. The big one being the TCS CU, which you won't have in your car. Anyway, with an auto ECU (which I have running my originally auto NeoDET in an R32) Nistune allows you to put in a Stagea image which doesn't panic about the absent TCS, and allows you to override a whle bunch of other annoyances that would otherwise see the check engine light on 100% of the time. Also, you can't wind up the power very far on the stock NeoDET ECUs without Nistune, because the boost sensor gets in the way. Nistune allows you to push that problem much further up the dial. Do you even have the boost sensor with the engine? Without it, you are SOL and will need an aftermarket ECU (or to find a sensor somewhere, god knows where). I can't tell you what the wiring loom differences are in a 34. But what Duncan said above needs to be considered. When you say "loom", does that include the transmission loom? Because you will need to swap out the auto tranny loom for the equivalent manual loom, and get rid of the neutral/park start interlock (basically hot wire it).
    • I have had the r3c in for years now, maybe close to 7 years and it has never missed a beat, anyone can drive it. Super easy to drive around town, the hotter it gets does get a little hard but it holds the power easy as
