411rwhp from stock internals

On a certain website, the R33's weight is 1390 kg while the R32 gtst comes in at 1260 kg.

It depends on which series and year it was made. The R33 GTS-t coupe weighs in at 1360-1370 usually, with the sedan coming at 20kg more on all variants (which is where the 1390kg weight would fit in).

The series 2 R32 Type M coupes weigh in at 1320. I don't know why they added 60kg on between series 1 and 2 for the R32 but it's gotta be the worst of both worlds. The power of an R32 with the weight of an R33

Equipment like turbos, bigger brakes, active LSD, ABS, air bags, bodykits, sunroofs, etc all add weight, so it's impossible to say "all R33's weigh Xkg and all R32's weigh Ykg." It varies by a fair amount.

I alwas thought the R32 weighed in at around 1280kg's.

I might have to throw it on the weigh bridge up near home.

haha... silvia with skyline power.. 1200kg... .. dont mind me..

Well, it does But give or take depending on what year model and what options it has.

Hi Buster Ben uses his car on the circuit as well, so I guess that's why he wanted a 2 way.

Hi guys so many posts on this thread while I was attending to some Bathurst business. Let me try and catch up...

Firstly, I noticed Wolf updated their web site when I pointed out that it did not show any Plug In ECUS other than S14 200SX. Glad to be of help guys.

Hi Steve-SST, I have read a few of your articles and noted the type of work you do on cars and your philosophy is not much different from mine. Which is a little unusual, there are a lot of people who are only interested in the single maximum power number. It is good to have someone with your experience and skill contributing, I really appreciate your contributions to this forum.

But (there is always a but, isn't there?) you are a Wolf dealer, so it is in your own best interests to promote them. I would like to give Wolf another try, but I keep adding up the cost and it works out more than a Power FC, a proven product. Why should I take the risk? When there is no cost benefit. There is more mechanical work involved in fitting a Wolf, which equals even more cost.

To answer the technical differences question please refer to the post on Wolf Vs PFC.

[GTS-t VSPEC]

Sydneykid, Glad your back, thought we had upset you:D Steve does sell other ECU's and does tune PowerFC's, but if the costs are equal then the Wolf has far more features and comes with laptop software which makes it easy to tune.

Mechanical Work involved in fitting the Wolf? Surely not with the plug'n'play's, which are as easy to install as a PowerFC.

[Cubes]

I was quoted $500 to tune the Wolf3D to suit the new motor/turbo/injectors.

PowerFC is a good option however the Air temp/Engine temp compensations with boost/ignition and fuel sounds very very attractive.

I would rather feeling safe to put my foot down just after sitting in a traffic jam and knowing that its going to pull some boost, timing and dump a little more fuel in as not to detonate.

Especially spending close to 10k on a motor/turbo/injector setup.

[BU5TER]

Sydneykid I ran the car again last week at Eastern Creek at full power and it produced a 11.930 1.991 60ft @ 122.18 mph, I think that places me one above the HPI R34 in the HPI Street Drag Challenge

[Sydneykid]

Well done Buster, that's a great effort. I reckon there is another 0.4 second and 3 mph in it. Please send it in to the HPI boys, we only want Skylines on that page.

Hi GTS-t VSPEC, maybe I missed something, how do you get a MAP signal? Or a knock signal? Without doing anything other than plugging the ECU in?

[N I B]

A map sensor lines no big deal. GTS-t VSPECs car is about to see if it can live thru another Dyno shootout this weekend, 50 50 chance i think.

[Cubes]

Why 50 50 chance if it isn't detonating or running lean?

Generally I have always seen cracked ring lands etc. Which is due to detonation/lean. Unless I am wrong? Probably!

[rob77]

stock pistons can only live so long on 411hp @ wheels (well over 500hp @ engine) plus I think he's running close to 17psi which is getting to the limits

[GTS-t VSPEC]

I hope the 50% lands on my engine still being in-tact.

[Sydneykid]

Com'on Steve-SST, "a map sensor lines no big deal", maybe for you and me, but it stops the Wolf being truly plug in and go. What about fitting a knock sensor, that's not so easy? Since an often quoted advantage of the Wolf is no airflow meter, don't you have to physically remove it? Fabricating and mounting a replacement is quite tricky, especially if you want to take full advantage of not having an AFM, by replacing the entire inlet pipework. These are not easy, 5 minute jobs for a backyarder.

I have a question that's been hanging around for while maybe you can help me with.

When you fit a MAP sensor do you run a hose from the plenum to the sensor? Is it mounted inside the cabin? On the firewall? Somewhere else? Or do you mount the MAP sensor itself direct on the plenum?

If you run the hose from the plenum to the sensor, do you find any delay in response? It takes a few 10ths of a second for the pressure to travel through the hose, so having it as short as possible would be a good idea. Mounting it on the plenum would of course be better but it involves some fabrication work. So is it worth it? ie; is the improved response noticeable?

Thanks for any help you can give

[N I B]

We can run internal or exturnal MAP or MAF or even TPS V MAP for GTRs with no MAF can you?No. Like Autronic ECUs Wolf has no problem with the inbuilt MAP sensor but we can run with different options if we want.I'm finished with this thread so please only post the facts.

[Sydneykid]

Sorry Steve, what did I say? All I asked was, in your experience is the improved response worth the trouble of mounting a MAP sensor on the plenum? Compared to running hose from a remote MAP sensor.

It is just that I have never tested it back to back and I wondered if you had.

I apologise if it came across as anything else.

Paul, I think the only area you may have dramas is with your injectors running dry, as you are already at 90% - boost isnt too high, and the bottom end should be fine for acouple more pulls - easily. Remeber JMS red R33 put down 446odd rwkw with stock bottom end - you are *only* running 411rwhp:D

Anyways, good luck hope all goes well and those injectors dont decided to call it a day.

[Roy]

Ive now read several posts concerning the JMS RB25 making 446rwkws.

Can someone shed some light on this engine, namely the turbo setup it was running and whether the thing was an import yard special, namely "we have 50 other RB25s out back so if she blows...mehh who cares"

I suspect the engne was a bit of a Saturday "qualifying special" and was never intended to see extended service as a street car/track car etc. Could be wrong but interested in hearing more about what was actually achieved on std internals
