in my 32 gtr

when i hit boost say 3000 - 3500 or so rpm the car feels like it goes slower

revs jump up but you actually feel like you lose power!

im thinking it may be a clutch slipping

does anyone have any ideas or had the same problem

Sure, if your driving, and hit peak tourqe and the revs flare, but you aren't accelerating anymore (or minimally) then your clutch is prolly slipping. Does it re-grip later in the revs?

Get a mate to drive behind you, he should be able to smell the acrid smoke.

clutch slip for sure dude!

find level ground, apply hand brake, push clutch in and select 4th gear, let clutch out slowly.....if it stalls your clutch will last a little longer if your cruise round off boost, if it doesnt stall, she's a rooted!

When you replace the clutch, it would be worth getting a new rear main seal and your flywheel machined. The flywheel machining is critical as if you dont get it machined, you can get severe clutch shudder when taking off with the new clutch is installed.

^^^ No offence, but f_ck a flywheel skim, assuming your on a mission to mod (its a GTR) grab a twinplate and lightened f.wheel combo now, otherwise you'll just be trying to hock your newish OEM clutch and re-surfaced f.wheel in the for sale section down the road.

      I've owned a few scooters over the years, a Vespa PX oil burner was my first scooter, followed by a few others, including a little 50cc BeeWee that I used as a barracks bike, and I've had a blast on all of them, they really are the cheapest for of city/suburb transport around The only issue with scooters in Australia is lots of people look down on them due to their size,  maybe they need a big bike to make up for something else where they are lacking, unlike Europe and Asia where every man an their dog owns one, and now that filtering is legal in NSW, local traffic is never a issue Not to say I haven't owned my share of big cc bikes over the years, but they were for more blasting through the hills or Hwy riding where it needed to sit on Hwy speeds Safety wise, I ride like everyone is always trying to kill me, everyone is running a red, or running stop/give way signs, or generally asleep at the wheel, which most people are duringtheir commute, I also ride really safe, and give myself, and everyone else enough room in case I need to pull some hasty evasive actions, I've done a few rider training days over the years, which has come in handy on more than a few occasions  As for mods, there's nothing really, and yes your right about aftermarket exhaust, all you get is loud and obnoxious noises from them, like every 250-300 cc you hear with a aftermarket muffler, in saying this I did put a rear muffler from a 125 Aprilla on one of my old 125 scooters, it was horrendous and no amount of full face helmet and ear plugs would dampen that noise As for coming from the Harley, and what a overpriced POS that was, I no longer do big rides as my poor old busted joints ache after about 1/2 an hour of riding, long cruises are so much more enjoyable now in a car, so a big bike would be pointless

      Oh wow, it's easy to forget how cheap these can be. Probably the cheapest way to travel. Though people in cars here tend to be morons and I would not feel very safe. Were scooters ever big in Australia? It used to be the thing growing up in Europe ~20 years ago. 50/70/125ccm Peugeot or Yamaha and some others. Utterly obnoxious Polini race exhausts. Kick stands that slant as much as possible. So loud. So much noise for really not moving very fast at all. But it felt cool at the time. Not sure where I'm going with this, but there is an aftermarket for mopeds! Though I'd have pictured you more for a Goldwing kind of guy after growing out of the Harley.

      As the MX5 isn't apparently "manly" enough, and I need something for runs to the local shops, and also take to my part time job at the salon, basically I can keep the MX5 away from car parks and stuff......like "flying lockers", I was wondering what I could buy to fix this issue LOL, I pick up a new Yamaha 125 Delight this arvo from Trooper Lu, basically a R1 that you can fit a slab of beer on between your feet, also, it was $29400 cheaper than a R1, so actually it's 2 x better than a R1
