Sequential Tranmission on the street Im looking at possible putting one of these into a car i have. Those that have driven a car with this transmission can you tell me how is it for a street car? Im looking at one without the straight cut gears. Sounds like MTI makes one.
Please post your input.
thanks

Really depends what aspect you're concerned about.
IMO straight cut gears these days arent as noisy as they may have been 20 years ago. As long as there is still some rubber mounting the noise wont be too obtrusive at all.
The one you're referring to is presumably the PPG ?

From 31:13 onwards, but entire video is worth a watch
As for shifting...a lot will depend on how you shift. ie, if you're running proper closed loop shifts via a load cell and also throttle blips during downshift. The setup can be configured to drive very very smoothly at all times.
If you drive in a manner where you are just using the clutch and shifting up/down without using a control feature then yes they will be a little clunkier, no different to any faceplated or dog engagement style H pattern
Really though the price of their T56 set needs to come down substantially...it aint cheap at all ! and ratio choices arent fantastic either although that seems to apply to most boxes.

This is a video of the fastest T56 car in the country running our shifter.
This is our Corvette shifter. It has the fastest shifts of any shifter on the market (except a sequential lol)

Here is the same car as above at the drag strip, obviously not normal use for this but it works.

Of course a sequential can and does work extremely well for drag use. My point was that someone looking for a sequential transmission....will usually be racing where it involves more than 2 or 3 shifts per race, so trying to then sell a manual H pattern shift seems totally irrelevant to the thread..

When I enquired a few years ago, they were talking around $25k.
And googling did seem to bring up a few unhappy customers. Even their email replies to be made them sound like Chinese desperate for your business with what seemed like rubbish vague generic responses
But visually their product looks nice, it can be had in 7 speed if you want and with a large number of ratio options ( still dont recall any that offered nice tall gearing though )
Either way, $25k is insane.
The Samsonas box is around $11000, obviously depending on exchange rates and any import duties ( plus fitting etc )

For most mere mortals, the sequential shifter as is close as we'll get ( if they ever get it to production ! )

A true sequential would be pointless on the street. They are finicky and require constant maintenance.
We use Emcos in the old world challenge/grand am corvettes. Some issues at first, but Emco worked on the design to improve them. Still not bulletproof though. The magic came when we ditched the stock diff for the Emco unit. The adjustability in ramp rates is incredible and offered huge gains in lap time.

Lithuania. I've emailed them to see if they can do a 30T output and what the overall length would be, and if it could be literally a direct swap for the T56 in terms of length etc, ie no shaft mods which would be great, awaiting a reply.
They also have some new taller ratio options and a lot of transfer gear options so you can play with the overall gearing, basically like changing the final drive.
I still can't quite get the gearing I'd like, but it's very close now. With exchange rates varying all the time, the Aussie sequential shifter is getting much worse value the more they **** about, and for me this is looking like a more sensible option, then I could just sell all my T56 stuff

Price is there for all to see, and really they are great value. Obviously shipping and any duties will bump prices up depending on location.

I have had my eye on the S1 sequential shifter for use on my T56 Magnum if they ever get off their *** and start selling it. They are a bolt on replacement for the standard H pattern shifter.

Here is a video of the S1 on a standard street T56.
