Smiles per hour GT86 review
 

Not sure if posted, did a search nothing came up. Another review of the GT86.

2 things;

1St: anyone notice how everyone who`s reviewed this car seems to have a perpetual grin from driving it? Awesomeness

2Nd: sounded like it backfired a bit in the vid. I think i hear that often while.driving spiritedly. Anyone else have that with theirs?

I have a grin every time I am in this car and I see a corner or roundabout in front of me :)

I just watched the video again and I failed to notice any backfire. Can you please point out an approximate time in the video?

Memo to reviewer: It "chirps on downshift" because you failed to rev-match properly, no other reason....

Isn't there actually a piece of equipment in the engine near the intake that exists to reduce that sound? Like a honkbox or something?

HAHAHAHAHA.... awesome.

The chirp in the video has nothing to do with the engine. If you down shift at high revs without rev matching, your rear wheels lock up momentarily. As Sport-Tech mentioned the guy didn't rev match.

it's at about 4:20-4:26 might just be how he, and i, shift. :iono:

Not to be pedantic, but the wheels don't really lock up--quite the opposite in fact. Consider the downshift sequence:

-------------------------------------------------pre-clutch shaft rpm --- post-clutch shaft rpm
1. 3rd gear engaged: ------------------------------- 3000 --------------- 3000
2. clutch in, shift to 2nd, no throttle change ------- 5000 --------------- 3000

Now when you let the clutch out quickly the engine will suddenly accelerate the driveshaft harshly since the pre-clutch (engine-side) shaft is spinning 2000 rpm faster than the post-clutch shaft, thus causing the rear wheels to lose a bit of traction as they are suddenly accelerated and so they chirp, they don't lock up. It's the same process (at a less dramatic level) that happens when you dump the clutch at 4000 rpm from a standing start and lay rubber.

Chris Harris he is not.

If you are going from 3000rpm in 3rd down to 2nd without reving the enigne up, you are slowing down the wheels, de-accelerating, aren't you? The engine wont suddenly accelerate unless you add more gas. If anything you are pretty much stalling a moving car (except the fact that it's moving means the engine will stay on). Only after this initial shock may the engine slightly increase in revolutions if the car is still travelling faster than 2nd gear at 3000rpm permits.

Also, if I remember correctly, this type of driving technique is called a Shift-Lock in drifting circles. Thus "locking" up the rear wheels wasn't too far off the mark as it tends to do just that.

^Yes you are right - - never going to figure gearing out at 2:30 AM ever again :bonk:

My mistake was saying that with no throttle change the revs on the engine would jump to 5000 rpm from 3000 on shifting - in fact it'd stay at about 3000, so with the gear downshift the driveline would suddenly be rotating more slowly, too slowly for the speed the car was rolling, and the tires would chirp.

I highly doubt that he actually had trouble out accelerating that particular Hyundai. You aren't doing it right if you can't. Fun review nonetheless. Toss the car into a few corners or roundabouts and you immediately realize the reason to buy it. Definitely have to measure in smiles per hour. Sometimes gets a little old with the "It's not fast, but it is fun" mantra that you hear so many times. I am no Stig, but, if you drive well, this car can be very fast. I guess that is the difference between a fast car and a fast driver.
