Had 3 clean runs in total tonight, glad the box held together..

R32 GTR (400kw) Full street trim

Run 1 (light take off) 13.653 - 3.4 = 60' - 124.30 mph

Run 2 (6500rpm release handbrake) 11.346 - 1.87 = 60' - 126.76mph

Run 3 (7500rpm side step) 11.494 - 1.882 = 60' - 126.05mph

It was very hard to keep traction in 1st & 2nd, the track up here in Nth QLD isn't exactly flash.... After the 1st run I got my notice that I ran a too high mph & that this would be my last meet until I get a harness, which im not keen to do (drive line's saving grace) so now I can only speculate..

I know that every second that comes off from your 60 equals 2 at the end... What im asking is ... "what do the above speeds equal to on a well prepared track"

I uploaded a video of one of the runs to, I apologize for the poor quality was shot on my phone..

Nice work, I got similar times with the 32, maybe I should of slipped the clutch a little lol!. What rubber did you have?

Half worn Potenza adrenaline's (255/40/17) ... The track wasn't very well prepared & resulted in poor 6o's.

I dunno about that.

I once had a car that genuinley made 400kw atw but had shite power delivery and a shite power band and only ran 126mph also.

On another note supporting your case I've also ran 126mph in my current GTR when it had 295kw.

just my 2c as I hate the ol, your car can't be making that power comments... :cool:

The first thing 126mph says is that the car isn't showing 400kw.

you can't make half a response :cool: Tell us what it is really making :sweat:

126mph should = high 10's

Oh, and Tomek, you ARE welcome back to the track...you just have to have the appropriate safety gear (and licencing) :cheers:

Judging by a et calculator your car should be good for a 10.63 at 126mph this is only an estimate calculator but so either more or less is possible. This was calculated at your car mass (3256 pounds or 1480kg) and power (400kw or 536hp at the wheels).

We use this on our drag car and found it to be fairly close most of the time

If you wanna (or anyone else for that matter) play around with this so you can see for yourself the site is http://www.wallaceracing.com/et-hp-mph.php

and you just need the weight of your car and hp.

On this site you can also find the power the car has through the wieght and et or the mph and et.

It is in american so you need pounds and horsepower to work it out.

Hope this helps

Cheers Matt

It would have to be a ferociously shit-house power delivery to genuinely make 400kW and run 126mph. My car made 335kW on the same dyno I've always tuned it on and ran 128.51mph @ 3243lbs. To be honest, the 335kW figure isn't really represented in the weight for power calculation either but it's a darn site closer than 126mph and 400kW.

The OP also mentions shitty street tyres and bad 60' times which will normally help mph (and hurt ET) so this isn't right either (even though the sixty was a respectable 1.8).

I'm not taking anything away from the run. 126mph is 126mph after all. But Blind Freddie could see in the first video posted that the power delivery is good and that the gate is open more often than it's not.

got a mate that runs 125mph with an R32 GTR and it makes 300rwkw on UniGroups dyno so your 400kw is way off the mark. His car is also a complete street car with NOTHING stripped from the interior at all and races on Bob Jane All Rounders.

If its making 400 it should probably be capable of a low 10?

Post up your dyno sheet if you can

Interesting thread as I will be running mine soon. I think it just comes down to different reading dynos. I dont just mean Tomek's pass where some are suggesting he is making less then 400, but also results like the 126mph that wrxkilla ran with only 295kw which just doesnt seem enough power for that result. It just proves that you cant compare dyno figures unless its done on the same dyno and the same day.

Car sounds awesome dude! Love the 290 one too lol.

A set of drag radials and a 1.6 60ft will see you into the high 10's.

My boss tuned a R34 that weighed 1650kg, made 360kW at the wheels and ran 11.6 @ 122mph also with a 1.8 60ft time.

I have run 134mph with 291kW at the wheels and 137mph with 387kW at the wheels, both on the same dyno, different turbo combinations. Power delivery has a big play in trap speed.

I agree, I know of a GTR that makes a genuine 550wkw, runs low 11s @ around 125 as the power is just way too peeky and not suited to drags at all IMO.

Just another example of how dyno peek power can mean very little in real life situations.

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      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.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      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?

      M35 Brake caliper replacement

      By Duncan · Posted

      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

      Jacks that fit under GTR lips that can reach the subframe?

      By Duncan · Posted

      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
