Forged Astra VXR Hits The Dyno! (Will It Survive?!)

- After my 300bhp Vauxhall Astra VXR / Opel Astra OPC blew up its engine a few months ago, I had the engine rebuilt with forged pistons and rods. After the rebuild, I went through a long 1000+ mile break-in process, and it's finally time to get the car back on the dyno with @manaperformanceuk to make sure the map is safe for a track day later this month, and to see if we can get any more power out of it!
Love the explosion 🔥 Glad it's all sorted and running smooth again mate 👍
Cant wait to see this
Decent result mate for no inlet numbers are just pub talk anyway it’s how it feels on the road top video mate
Thanks mate, feels amazing on the road now and that's what counts like you say 😁 if only we could put it down in this weather though!
Good luck mate pick mine up from rnd next week full new built engine 😂
Nice one, I'm sure it will be amazing I've heard good things about RnD!
Yeah we need a pov please
Nice number plate, how much did it cost? Just about to watch the Cadwell Park one in a bit
Thanks! It's the cheapest style they offer, so only £250 including the fees
Are you from Sheffield
Great stuff, what turbo? Ko4
Yes stock turbo 🙂
@jamesbalazs what exhaust manifold and exhaust are you running?
I've got a Klasen Z20genx and a standard 2.5" exhaust.
Making 295 hp, but according to the Facebook I'm running too much boost - 1.8 bar.
Get a 3" exhaust will unlock more power torque. 1.8 bar is a bit high tbh, 1.4 should be around the max. Anymore and the turbo and possibly engine wont last unless its forged?
Standard manifold and turbo on mine, and it does 1.3 bar.
The exhaust is 3" downpipe into 3.5" catback with a sport cat and 2 silencers.
Before wrapping the downpipe, you must soak the heatwrap in a bucket of water..
I addressed that very clearly in the video. The manufacturer states you *can* but do not have to. It simply provides a slightly tighter fit.
Can it gap BMW e92 335d with 360 bhp regardless astra is lighter than bm ?
Probably not, I'm sure the BM has much more torque and slightly better power to weight
