Strongest sequential and why?

With RBs pushing power further and further past 1000hp the demand on a gearbox is ever greater. 10 years ago a 1000hp transmission would be considered unbreakable. Now, with the cost of power parts going down and quality going up, the same person who could afford a sequential 10 years ago would be aiming for a number far higher then 1000hp. Keeping the cost aside and keeping dedicated drag boxes out of it (would love to see a thread on Liberty and Jericho transmissions)

Are transmission manufacturers keeping up?

What is the strongest sequential out there?

Why do you think/know so?

I am leaning towards the Hollinger. Been around for a very long time, very widely used in motorsports. Seems to be the only one with straight cut gears which eliminates sideload.

The Holinger sequential for GTR uses helical cut gears, as does PPG and OS 88. Samsonas and Albins use straight cut 

I think most would agree Albins would be top of the food chain

You're right, back in the day, most of the GTR's though were either 2.6, or 2.8 only. RB30's werent THAT common.

I was in this exact boat when planning for a gearbox. I went with a 3.2 route. I sussed out all my options and talked to a tonne of people around what options there were for GTR's(excluding auto's here):

* Getrag 6 speed
* Gearset
* Sequential

Personally, I wanted peace of mind hence why I didnt go for a gearset or 6 speed. I mean, by the time you've done either of those 2 options you wouldn't get much change from 15K right? Plus, I dont know how long they would last with the fat torque of the 3.2...I also scoped out the sequentials out there, and in the end I went with the Albins as to me it seemed like the pick of the crop(Not saying the other Seq manufactures are shit, but its just my opinion). Plus, the Albins kit literally comes with everything minus the clutch.. no faffing around looking for tailshafts/transfer cases etc.

I have a Holinger and love it, I bought it a few years about now circa 2015

 

however Albins and Samsona's seem to be the pick of the bunch these days.

 

Particularly now the albins can slot straight in without panel beating and the adjuster gear to tweak ratio's is very convenient and samsonas seems to put up with the beatings

I was under the impression you could get either, as the Holinger GRA-6N box for the group A R32 cars were straight cut, and was essentially the same ?

Anyway I would echo above - Albins all the way. Compared to Samsonas they have definitely more all round Motorsport proven track record within Australia and are completely Australian. In off road like 800hp+ buggies with monster torque that race here in the NT Finke desert race, there is basically only one manual box used that wins.

I called them not that long ago to ask a few questions about their sequential, they never mentioned anything about the option for straight cut? But I didn’t ask either, but the standard sequential design is helical cut.

Standard option looks like it, as the pictures in Holinger GTR workshop manual are all showing helical gears on the disassembly except reverse. Main and counter shafts are both splined on gear so they definitely can do it. The earlier GTR boxes the Hollinger GRA-6N and HKS-GTR were only straight cut.

Same experience as Moray - when I spoke to Holinger couple months ago - helical only.  Not sure why that is now - as I'm sure you could get them in straight cut years ago.

I went with the new Albins ST6-LP - i believe its the only one with a internal oil pump.!

      Who has a Infiniti Q60, Q50 (V37)?

      By Duncan · Posted

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      R34 25GT Engine Light 21

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.
