Was that on JEM's dyno? Man, I'd love to see what Mat's thing would run - even just mph, I would guess it'd be near 130mph

:whistling:

I'll get it there soon enough!

No Point in starting a new thread so I might as well use this one.

I ran at Calder on Friday night and the best I could manage was consistent 12.6's on shitty tyres and old tien coilovers that are as hard as a rock. MPH averaged between 108 and 112.

My car has dyno'd at 325 rwkw and it's a full weight 32 GTR.

What are peoples opinions on the low MPH?

I'm considering stick it back on the dyno and maybe checking for some boost leaks?

I would simply say the dyno is reading high to begin with and if there is a boost leak that the tuner didnt pick up on dont go back there. How much boost were they using to make 325rwkw? and what turbo's? built or stock engine?

I have a mate that has that much power and runs 11.3 at around 128mph so there is most certainly something not right with what your saying

Well the car was dyno'd around 18 months ago so anything could have happened between now n then.

The car is running 20psi on -7s with a built motor.

Either your mate has a completely stripped car or he's making more than 325rwkw in a r32 gtr to run 128mph.

complete car, no stripping of anything at all, not even the ppare wheel. The car drove to the track, ran on Bob Jane All Rounders, and drove home :)

Only internal mod is some Tomei drop in cams and cam gears. Daniel has had heaps of runs and knows how to get the thing off the line

Here it is a many years ago, pre cams, against a 32 i helped build that made 460rwkw. Skip through to about 6mins 45, its the one that does the burnout

That does seem low mate, the MPH that is. I would have thought at least 118 to 120 and into the 11s with 325rwkw.

Is it a hub dyno or roller? Can you do a power run elsewhere to get a sense check?

      Oof, I will forevermore have those shredded gears in mind whenever someone talks about showing mechanical sympathy towards their car. Thanks for the photos, fascinating stuff!

      RH9 R32 GTR Build Thread

      By OST Micah 路 Posted

      The holdups last year were drivetrain related. I had the car out right after getting the bearing issue resolved. Third launch and the car didn't move after releasing the clutch. It had sheared all the engagement teeth off the 1st gear.    Thankfully no other damage was done. I set an aftermarket gear beside an OEM gear and found that the engagement teeth on the OEM gear were much larger and better supported. Looking through my bin of spare transmission gears I found that there are two types of tooth on the OEM first gears - the larger tooth and the smaller tooth. It looks like most aftermarket gearset manufacturers base their design on the smaller tooth. OEM large tooth left - Speedtek, OS Giken, etc or OEM small tooth right Decided to give that larger engagement tooth a try. Pressed the ring off an OEM gear and sent it to a transmission manufacturer here in the States. They did their "faceplating" operation with my synchro ring on the Speedtek gear.   I reassembled it, took it back to the track and promptly destroyed the gear itself.  I'll rebuild this and use it as a spare - thankfully just first gear and the countershaft are damaged beyond repair. Definitely disheartening but my welded on engagement tooth ring held up!  Moved to Speedtek's dog engagement design as the gears appear to be much stronger. So far they have taken much more abuse at the track. Also scored a Stillway lockout from the Netherands for super cheap. It's for some other RB transmission so it took a bit of fabrication to fit but honestly a very easy job. I also had to heavily modify the gates as they were very different.   Then for some reason at the last test and tune a silicon coupler below the throttle blew off and took out the radiator and fan. Thankfully it was in the burnout box and not down track. This car is really beating me up - I still haven't made a pass in it. Ran it through the gears many times on the street but it keeps biting me at the track.  Currently in the process of replacing the radiator and remaking the throttle pipe to remove the coupler and use a cast 90 and a vband. I WILL get this thing down the track...

      Covers most of the above points really. There's a few exceptions but most just see driving as an irritating but necessary task they must complete if they want to get anywhere on time. Also see it as a good time to show their awesome multi-tasking abilities on their mobile and/or doing their makeup.
