NF,

Yeah the thread I posted didn't really say anything definite, and a lot of crap was posted, but I just thought I'd post it to show dynos read a little differently around the world.

I also reckon the real power figures are in the quarter times. As long as the driving is consistent.

Cheers,

Michael

DYNO's ARE FOR TUNING!

There is no real point in comparing different dyno readings between cars on different dynos. Unless you are a bit bored.

If you are tuning your car , going back to the SAME dyno makes alot of sense.

The 1/4 mile is a sport and not a very strict indicator of power, there are even more variables than comparing dyno results. ie: if you don't get the right equipment to play the sport you may not do too well. Like playing golf with a hockey stick.

I guess asking for peoples dyno results with a similar car setup will give you a range, which if your car fits between can give you some peice of mind that nothing is terribly wrong.

What does doing a dyno run in a lower gear do to your figures? I assume the torque will read higher because there is more of a mechanical advantage, and the power will read lower because the engine is physically doing less work to get the extra torque.

Does anyone know roughly how much I should adjust the figures if the dyno run was done in 3rd instead of 4th? Assuming factory R33 GTS-t gearbox ratios (I don't know what the ratios are).

164rwkw from a R33 with 11psi, no other mods.

Seems way too high to me.  Perhaps its just blue cars make extra power.

Yeah right - blue cars !! he he

I reckon the extra Kilowatts came from the energy permiating from the two good lookin blokes in the back seat at the time of the run....:D:)

Seriously, with your sticky tyres and the extra weight in the back, I reckon there was less slip against the Dyno hence the better results. :cool::) (that sound like BS to me actually.)

Duncan , last time I ran there - I got 150rwrw with std boost and a cat back zorst - so a few extra PSI could make the 13rwkw diff, maybe ???

It depends on how the dyno is callibrated and what gear the run was done in. What was your torque out of interest?

Hi Jim,

Done in 4th gear. Unfortunately, the graph only has Air/fuel and power on it. I'm sure they logged torque as well, but I don't have the figures.

I think Broken got the figures for all cars, he might be able to post them. While good traction would have helped (definately no wheelspin there!), I suspect its a friendly dyno....

I dyno'd my car yesterday also (with Broken and 25 other Skylines)

Specs:

'95 GTS-T

Cat Back 3" Exhaust

HKS Air Filter

FMIC

2 Stage boost controller

First time i've ever had it done (only had the car 9wks)

7psi = 169 rwkw

12psi = 192 rwkw

Not bad for a first run , I was extremely impressed.

All i need now is a CAI, Side windors Tinted, oil change and my driver side window fixed and i think i'll just throw fuel in her for the next 3-4mths while enjoying the ride.

      Ahh got it. Well maybe install a drain for the catch can somewhere down low and accessible like a wheel well too....

      Before you blow your car up, have you checked you've made all the correct modifications to the wiring if you're still using the RB20DE loom?   Some things to look at: The pin used for the map sensor on the RB25DET, is the same pin used on the RB20DE for the Ring Gear Crankshaft Position Sensor, no idea what you've got it plugged into now. The turbo pressure control valve solenoid you're talking about on the RB25DET, the same pin is used for the Variable Air Intake Control Valve on the RB20DE.   The factory manual has the wiring pinouts in it for you to check everything. It also has the diagnostics process to read codes out. In addition, there's a great table that shows what sensors and what actuators not functioning will relate to which signals. And Nissan confirm the as everyone else has from experience, the Solenoid being disconnected won't cause a fuel cut. However, the turbo pressure sensor being missing / wrong, WILL cause a fuel cut. https://www.nicoclub.com/service-manual?fsm=Skyline%2FR34-Workshop-Manual-English.pdf

      I've been hunting info on the G Series II - this is best I have found so far(Link below). Still waiting on the G35-1150 comp map, kind of very keen   So how do we go about getting precision on that little table of yours ?   https://turbosbytm.com/sites/default/files/product/technical-info/Garrett-G-Series-II-Product_Flyer 25 30 35_1.pdf

      yeah I get ~0.6L per session into the catch can. very ethanoly. It ends up overflowing out the breather of the catch can on circuit days too even with a 2.3L capacity catch can and I only drain out ~0.6L max. So every session I have to come in and drain the catch can, which is a hassle. So this is me cracking the shits and doing everything I can without removing the motor (back of head sump drain/breather and oil restrictors off the table). plans short term are: full length splash plates remove oem cam cover baffle add foam and reinstall at -10 or -12 AN fittings to the side of the cam covers down to the sump (luckily I already have fittings in the sump) Yes the ~340,000km unopened motor is probably not helping things

      I'd use any fuel safe foam....mine went in 15 years and 15 rebuilds ago, still getting reused I'd have to say I don't understand swapping to studs to fit a particular baffle unless you are having a massive blowby issue, and even if you are addressing crankcase not head breathing is probably the next step.
