LSX-GMH turbo dyno & drag

- Опубликовано: 14 окт 2024
- We've shown you quite a few turbo LS Commodores over the years but Chris' SS is one very sweet sounding street car. We'll see how it performs on the Allsparks Performance chassis dyno and then see if Chris can put a number down at the track.
Released around 15 years ago, the Holden VX SS Commodore was factory powered by the Gen 3 5.7L V8 engine making around 300hp. Chris' 2001 example is now upgraded with a larger LSX 7L engine built by Flowcraft Race Engines which features Brodix cylinder heads and a solid roller camshaft.
Boost comes from a Precision 88mm turbocharger, but as the GM computer is still in place boost will be limited to around 20psi. The fuel system is also E85 compliant. Backing up the engine is a Hasty Auto Trans Powerglide, but the weak point at present is the rear end. The factory Holden IRS is retained with the only improvement being a full spool centre.

Freakshow. Love how the head lights are even straining under a full power run. That's just plain scary for a street car.
Look at the intake pipe expand right before the manifold, damn
F#*king awesome sleeper wow !!!
Ross Palmer Nothing sleeper about a solid cam. Nothing sleeper about the sound of a turbo. There is absolutely NOTHING sleeper about that car.
SpecialKLSX yeah in that aspect true, just in street form it looks sleeper haha besides bonnet
Ross Palmer the bonnet is anti sleeper.. other then that youd just think its another loud and slow v8 till it goes
Was just watching this again and wanted to ask something. At the end of each pull, the car sounds and behaves like it's just hit the limiter a bit, but the in car shot show that the tach goes way higher in the beginning of the run as the converter slips and as the convt starts to equalize the wheel and engine speed the rpm get pulled back down. My question is, what was going on here??? Were the guys running out of ramp speed or something (they can only do around a 4000rpm pull throughout a dyno run in my experience- at least with engine dynos that's the case) 'cause when the car sounds like it's on the limiter, it's not revving as hard as it did while the convt was slipping.
whats the go with head lights flickering at high rpm?
So awesome!!! one of me new favs hahah yeew commy
1:44 turbo kicks in
I noticed Nexen tyres on the front?! I hope they're not on the rear of this thing!
Why's your audio track ALWAYS so much lower than everyone elses???
So the low boost setting is ONLY pushing twice it's displacement at atmospheric.
That's like a shit ton
Whats with the steam coming out at 1:17?
1.15 it kicks in m8
Shes flying past the camera position. Trapping 168 nice..

944hp wow
Barra Eater 😂😂😂
1 15
wow, an ugly old taxi with near on 1000hp. that must freak people out!
never seen a commodore taxi. falcons. all of em
Martin McMartin He's right, Holden never built taxi's in this era (taxi spec cars generally have extra seem welding and a few other bits and pieces different). Falcons were the choice of this era in Australia
Your eyes are painted on mate, looks killa and taxi's never came out with ss body kits.
@@orion5813 south Australia had heaps of commy taxis, more than any other make. Makes sence as we produced them here. Cop cars were all commys as well here. Hope I cleared that up for you mate.
@@danielbrealey2924 you only stay in your foad falcon state didn't you. Holden taxis and cop cars everywhere in Adelaide in its era. You just learned something mate.
