GMC Syclone Documentary (History and In-Depth Review) | Truck Central 

Absolutely!

Thank you!

Demuro is straight up obnoxious

And the blocky body didn't seem to hurt its performance. It could catch a Ferrari 348...

And sadly, they refuse to make a modern version of it. That's why I gave up on GM. They now lack imagination and don't want to make fun cars. I abandoned them and bought a MINI instead.

​@largol33t1 Well, GM didn't want anything competing with the Corvette, then they killed Pontiac, who worked with Buick and GMC to make the Syclone, so yeah.

Really cool story 👍👍 Love stuff like this… thanks for sharing!

Yeah, 13.83@103 was pretty damn good in the 90s!

Same here!

This one lol

my 06 2500 h.d gas i have been 137 not turbo but its fast, this video was done really cool nice job

2000 f250 7.3L tuned lol

My TMNT truck!!!! Check my videos

My 1992 GMC Typhoon.

My buddy is a camaro guy and his 2010 SS does not corner as well as my Typhoon (lowered 2 inches and big sway bar in the back)

It already has one, factory installed.

😳!!

They were all black

The Trans Am Turbo was single turbo. It was a slightly modified version of the Buick GNX engine.

@@rdsimmonds I'd have to read bit more I believe the pace car version of trans am was a twin turbo.

@@TheMusicKicks to the best of my knowledge, the pace car was a stock 1989 Trans Am Turbo. I know I've heard more than once that it was the first car to be used for the pace car that was completely stock.

@@TheMusicKicks my uncle owns a 89' turbo Trans-Am ..they are single turbo but run out very well!

Not built by PAS, just finished by PAS.

The Syclone was '91 only (well, there were 3 '92 models). The Typhoons were '92 and '93 only.

?

Well, it's more to do with it would take too much modification to the S10 platform to work with the 3.8L. So it was easier to use the 4.3L that was already available in the S10s. The Buick 3.8L V6 was still in production into the late 90s (maybe later?) and was used extensively in Holdens in Australia.

@@jeffroberge When I attended a syclone typhoon meet several years ago we had a speaker attend whom was part of PAS, the company that completed the syclone conversion. He did talk about the 3.8l during its design which they did have a test mule with the 3.8l. Gm killed that option because that 3.8 was being phased out while the front wheel drive based 3.8 went into production. Nothing to do with fitment to the s10, there was a "Buick" s10 with the gm 3.8. A SBC fits into an s10 with not too much modifications. That 3.8 would have been a breeze.

@@Tribbatrot Interesting. That differs a bit from what I've found over the years. I've owned a Syclone for 18 years, so I'm not exactly unfamiliar with them. But I'd say after 30 years, some of the exact details have probably been muddied a bit. There's probably some truth to most of what both you and I have heard and read since the creation of these awesome machines.

@@Tribbatrot you right pretty much. I have Syclone and Jimmy S15 2wd V8 TPI. Motor mounts were easy to do. Wheel housing fit with no problem

@@jeffroberge it definitely was due to the engine being phased out. The Buick 3.8 V6 will physically fit with very little issue. But the 3800 series engines that replaced the 3.8 and were available at time these were built were for fwd applications only.

@303StreetMachines ABS doesn’t activate or affect a vehicle when it’s already stopped and you’re not moving. If it did the ABS would always be pulsing and you wouldn’t be able to stay stopped at any time. We boost launched my friends Typhoon all the time and never needed the parking brake. Below is a an excerpt from the original Car & Driver magazine test for the Typhoon which mechanically is identical to the Syclone. Both are launched the same way for the quickest acceleration times. “For maximum off-the-line ooomph, you'll want to run up the engine against the brake. Okay, shift into drive, hold the brake down with your left foot, and lower the throttle until the boost gauge swings as far as it will go. Ready for liftoff? Just lift your left foot off the brake and hold your right foot to the floor. Whhooooossh! No tire smoke. Barely a chirp from the rubber. And you are gone! The sprint from 0 to 60 mph takes-get this, SUV mavens-just 5.3 seconds.” The owner of this Syclone says that his brakes are a little weak or something like that so I assume that’s why he used the parking brake but he may not know what he’s doing either. I’ve seen plenty of owners that didn’t know crap about their vehicles or how to drive them. Heck RU-vid is loaded with videos showing hundreds of owners like that. 😂

@303StreetMachines The Syclone and Typhoon along with the S-10 pickup, S-10 Blazer, Sonoma and Jimmy that had ABS all had issues with their ABS affecting braking distances and pedal feel due to the ABS system. But the ABS still doesn’t do anything when you’re stopped and Boost Launching a Syclone or Typhoon or any vehicle with ABS. Being a teenager in the early 1990’s I drove both the Syclone and Typhoon many times when they were new to the market as well as the S-10 and S-10 Blazer and Oldsmobile Bravada having owned all of them. They all use the same ABS systems. SyTy owners have been removing the ABS from their trucks for decades to have better brake control and firmer pedal feel when braking from speed not when they’re launching from a standstill. But disabling the ABS is more in depth than pulling the ABS fuse which I don’t remember the Syclone or Typhoon having because the wheel speed sensors are what control the ABS. Disabling the ABS in the Syclone and Typhoon requires removing the entire ABS valve body and redoing the brake line connections to the front and rear brakes. Regardless of all that your original comment that ABS makes brake boosting not so easy still makes no sense because like I said earlier the ABS only activates when the vehicle is at speed and the system senses the wheels locking up when braking and doesn’t do anything when you’re stopped and launching a vehicle from a standstill. I’m still going to assume that the owner just doesn’t really know what he’s doing and that’s why he’s setting the parking brake and then releasing it when launching.

@DOMMEX isn't the drive-train the same on the Syclone & Typhoon?

Correct. Also 1991 = long time ago :)

You seem well-adjusted. Thanks for watching our video. At the end of the day, that’s all that really matters… that *you* watched *our* video.
