considering adam Q has power fc, big mofo turbo etc etc etc and macka has PHAT turbo also with many other things on both cars, they're making around the 300rwhp, and adam 32 made around 270rwhp with a t04e...I'm skeptical about it

and like gradenko pointed out more than a gtr...someones been fiddling

Gtr read outs will be lower cause its taken at all 4 wheels.

I'm not too sure if thats how it was done at speedworks though.

But I know that at auto saloon, they had a fairly worked GTR 33 on the formaz dyno and it only read 250hp, thats 10 more than what mine read on the same dyno. No way were we that equal.

PSIKO, I wouldn't compare AdamQ's and mackas/adam32s figures with rob77s casue they were all on different dynos. If the figures of the others cars at the dyno day fitted in, I'd put it down to another high reading dyno. But the thing is, all the other cars have reasonable readings (I think), but robs doesn't fit in with them. The title on the bar graph that says "Compensated Power"... reads like compensated for drivetrain loss to me.

Hicks, true enough about 4wd/2wd, but checkout the figure for the other R33 25t that was there.

Not trying to beat you down here rob, just want to help you get a reasonable figure. :D

Bugger. Meracat should be in the 2001cc - 3060cc class then , not 3401cc - 4500cc. So really, they goofed. */me points fingers and passes the blame* :D

The classes, btw, look like they are worked out based on [cc of engine] for N/A and [cc] x 1.5, if forced inducted.

As per my list below, thats all my mods. As per the power output of the GTR vs my GTS25t, I have less drivetrain loss because I'm rwd he's 4wd. Yes you cant compare other dyno readings with mine as they are completely different dyno's. They arnt even the same. The dynapak dyno has the wheels removed and the dyno attached to the wheel hub, the car spins this and it works out the PS figure. As per what grandenko said the class's are worked out on forced induction times 1.5. But as it stands my car on this dyno has 273.5PS @ wheels, might I suggest some or one of you dyno'ing your car @ speedworks as well as to see what happens. Just a note... they found my intercooler, it went to the US instead of here. I wont be going to the drags until its fitted because my intake temps on 0.8bar are too high. The car sounded very rough towards the end of the 2 runs and I think it may have pinged slightly. But once I go I am confident I will run into the 13's, as rev210 has done. He ran twice at 14.3, then dropped his tyre psi to 20 and ran a 13.8 (on lower boost too, due to a hose slipping off).

Hmmm....

It does sound odd.

Here are last years results.

I still beleive these are fairly accurate because I know that PSI are very careful with the compensation factors. Those there may well remember the small presentation we got on it.

Now we have

rev210 aka Dave 188RWHP - pulls 13. 8

Me aka Nexus_Six 218RWHP- -pulls 14.1

Brett aka Evil r33 166RWHP (BUT THEN GOT PFC) pulls 14.5

Chris aka R34 188RWHP Pulled about 14.2? (correct me if needed Chris...)

Mike aka Micko 218RWHP pulled about 13.8? (Good ole Buffy)

Troy aka Skyzerr33 170rwhp pulled 14.01

Now there is a pattern forming here.

Most this cars at this time were mainly standard. Most had exhausts and filters and thats about it.

P:S any others put em forward..

This points to 1 of 2 things.. either 1 dyno is really out... of if Rob77 truely has 270+ HP surely it should be 12-low 13's?

Wiat up waitup!!

This seems correct...

This is "corrected power" not rated power.

Perfect conditions and also counteracts other things that may affect a proper hp reading.

I saw a reading from United Fuel injection not long ago and it had this on the dyno sheet..

Rear wheel horsepower

Corrected Rear wheel horsepower

Engine horsepower..

I didnt check but u might find the other cars have inflated figures too yeah?

Terminal speed is a better indicator for HP...

Rob in all reality, it would be nice to think that our cars are better than they are. Some dynos tell people what they want to hear. As Destroy said "Terminal speed is a better indicator for HP...".

You have run a 1/4 mile, take your terminal speed, get your car wieghed in the same trim as at the strip (with you in it) and this is the only way you will get a truely accurate HP.

To suggest that your car can get 273PS at the treads - when compared to what most people use, ie dyno dynamics is either wishful thinking, or you should be writing letters to nissan 'cos your car is a freak.

You have to get min FMIC, extra boost and management to even think about getting that sort of HP down. And you would know if you were, 'cos your clutch would smoke like a mofo - if its stock, which you should also know

Not meaning to have a go, just no point trying to compare apples to oranges.

Steve

At the end of the day this is what my car has run on a dynapak dyno thats all i'm saying. My clutch is not stock, its a 9 puck metal sprung clutch with a 2500 pound pressure plate. And as i've said before comparing dyno figures to other dyno figures is pointless, unless done on the same dyno and same day its not worth it. Whether my car *really* has 273.5PS @ wheels or not, according to the dynapak dyno it has. I'm sure if I went to a dyno dynamics and rolled the car up i'd get a different figure. You cant compare a dynapak to a dyno dynamics as they use a completely different method. As i've said before as well a dyno is better used to find how much more HP is netted from a modification. I didnt start this thread out to be "my car has more HP than everyone else" i just stated what figure the dynapak dyno read.

    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
    • You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
    • Funny, but really not funny. Thank god (most) f the world has moved on since then
    • Lots of votes for driving onto a plank first; that is the quickest way I've found, 25mm is enough for my case but that will vary by car It also depends where you are going for. On the 32 I can get to the rear diff with my floor jack if I do that end first, and get it up on stands. Then I lift the front from either front tow hook as high as needed, also onto stands. Sometimes I need a small lift on the other tow hook to get it level enough If I do the front first I can't get to the rear diff because of the angle of the car Other options are getting to the front mount of the rear subframe from in front of the wheel (if only lifting one side, or just do both which is a bit of a pain compared to one lift from the diff), or also the gearbox cross member mount on the driver's side if you are  just trying to lift the driver's side. I This is the jack I use; it says 75mm clearance but of course that is only on the lower section so if you have to reach too far in like the diff you still get stuck. https://www.snapon-bluepoint.com.sg/category/Floor-Jacks/product/Floor-Jack,-2-Ton-Low-Profile
