Forged Astra VXR Hits The Dyno! (Will It Survive?!)
Автокөліктер мен көлік құралдары
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!

Nice one, I'm sure it will be amazing I've heard good things about RnD!
@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.
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

Yes stock turbo 🙂
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
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.
