Hey guys
I always loved the GSX1400 since the first model with the white rims, and from the moment I sat on one at the Gold Coast bike expo early this year I just had to have one!
It was less than a month before I had a shiny new one in my garage:
The bike is great fun, has that classic look, and has gobs of torque combined with good brakes & handling. It does lack outright fasts (11.2@119 1.85 60ft) but the torque is unbelievable and the Staintune muffler & Power Commander I fitted made a good difference to rideability, power & the overall feel. This is a great 'do it all' bike, and aside from commuting I've been to the drags, QR, and camping on it.
Still, missing the 174rwhp of my previous ZX12R and not being one to leave well enough alone... I decided it was time to go turbo.
Engine is a low-revving 1402cc oil-cooled inline four, with an already-low 9000rpm redline being irrelevant given that the show really stops at 5500rpm and the bike benefits from short-shifting. With the breathing mods it opened up to about 6200rpm so the turbo is a logical choice to make use of the available revs - confirmed again by the very low 9.0:1 static CR compared to most cars which are higher than that and most modern bikes which are 12.0:1 or even higher.
The turbo I had made specifically for the project, but for lack of a better description it is a genuine Garrett CHRA (which I had to get from the states, what a headfuck) with knockoff Asia housings and can loosely be described as a T28.
The bike is currently in getting the main fabrication work completed.
Many thanks to JZK25, whose keenness to be involved in putting turbos where they don't belong has assisted in my pursuing an otherwise dreamy project.
Will post pics later this morning, once I've had my morning coffee.
Initially I will be looking for around 150rwhp which probably doesn't sound like a lot but by my maths the torque output should be about 140atw so it should be a crazy thing to ride. That's also a lot of power from a 1400cc motor that is more closely related to an old car engine than a modern bike engine!
Once the bike has had a bit of a shakedown I see no problems making a genuine 180+rwhp.
