Great video and this is not to pick any fault, but the crossover delete is not necessary either to see 300BHP. A standard airbox mod and a good panel filter is just fine. And will keep the bay looking stock. Win!
a lot better throttle response with cdti airbox
@@chrissingleton8473 perhaps, however hardly noticeable and still will make 300bhp
obviously you're never had the crossover delete then makes a huge difference keep intake temp down a lot better to
@@chrissingleton8473 Had 6 SRI Turbos, 10 GSI Astras, 6 Astra VXR’s all varied states of tune, so I think I’m well placed to say if it’s highly noticeable or not. Also it’s much harder to keep intake temps down with an Open air filter as apposed to enclosed one.
@@mikeprice8500 i don't run cone it's 1.9 cdti air box done by Courtenay sport they even said when they did the mapping they breath alot better an don't heat soak the same an use the same set up on there track car
Iv been looking for a straight answer to this question for a while now. Everyone says differently .
Because every build and car different.
True but when one guy says good map and intercooler the other guy says fully forged with a massive turbo
@@cloake494 whole different what you sad. Of course these days from the 100 cars 95 is used as sh** box. Lot of *** hole tune them with bad things and more…. the basic engine is not too hard to kill them as factory setup and tuned setup. That’s why recommend rebuild them. That’s the first good step. But if somebody rebuild the engine full original than you can tune them Phase/Stage1-2-3-4 max. Basicly the 1 is only map. You can use it. Better than original was but there will be always make everything better.
Great video man some good information there 👌🏻
Thanks mate! 😁
Thanks James. 👍
VXR😍😍😍
Funfact, upgraded inlet manifold you need because after 5000rpm you have power and not lose.
Totally agree, it makes a good difference but not *needed* for 300 or less.
Привет🤚Машина супер! 👍
Ive got all of the above but i have a 2.5 inch exhaust thats how i bought it, its been mapped but i havent got a dyno chart. Im not sure what kind of power its running its nippy enough when it puts it down
mine was running 298 however the turbo intake compressor wheel has decided to blow its self up >.> haha so new turbo incoming !!
Would be nice if you could tell how much $$££ it would cost to get a 300 bhp.
Mines 280bhp I’m happy with it plenty fast enough for roads I go on
I bet it is mate 😁 300 is scary and plenty fast on back roads, you can't put it all down anyway
@@JamesBalazs I drive out snowdonia a lot and I just feel anymore be completely wasted obviously not a straight line warrior but definitely good enough, I have k06 hybrid on too good for 350 I believe but I’d definitely want to forge engine for that. Definitely safe n reliable as it is for now
Сидения кожа, хочу себе такие!
You forgot the main mod - have a spare car in case the vxr end up on recovery truck and leaves you stranded without a car or at least have a spare engine if your current blows up!!

@@LiamPlesterwhat

I'm not going to argue. Fe
Merry Christmas
Oh boy, sure can't wait to go around neighborhoods and night with my 3 in exhaust fitted to my annoying 4 cyl
its the driver, not the exaust.
