ok guys, looking at getting the XR moving a little quicker.
Not toooo sure what to do, whether to get 347 stroker, or just stick with 302.
whats your recommendations ? this is probably been posted millions of times.
but i have just set a mental goal of about 260-270 kw.
At the wheels or at the flywheel? A guy in our club put a supercharger on his 220Kw XR8. It had 160rwKw before and I think around 243 rwkw after. That's about 350Kw at the flywheel. You should be abkle to get at least 220rwKw from the 200Kw motor. All up cost of around $9000.
yeah if the finance can handle it go the new car.
But other wise I'd be stroking it and talking to Herrods.
You could get 260 at the flywheel with out to much trouble from a 5lt (cobra heads/manifold/ medium level block work blah) but it would be more drivable with the extra cubes
If i'm not wrong Herrods offers a 250kw engine package which includes upgraded exhaust, cam and computer tuning. I can hazzard a guess that teh engine would be quite lumpy with the new cam.
but i love this car people, so upgrade will be later, i will spend the dosh on this one. I like the sound of the close to 300kw stroker from herrod !!!! Cubes sound like the go ~!
Dude if you love that car drive the Xr8 when it comes out before you spend the dosh on what you got.
You don't want to spend all the money just to find yourself wishing you'd got the new one.
Thats my advice.
My Brother has an Black AUII XR8 and he wants to get about 270kw. I told him to take it to Herrod . They have 250kw engine pack or as you said get Herrod to make it an 347. I told my bother to make it a 347 but he said the car will drink to much PULP
I went the Herrod 5.7 Stroker option. It's a good choice. If I were doing it again I'd be going with the bigger TB as well along with a slightly bigger cam.
Having said that the torque is awesome and fuel consumption has finally improved (hence the bigger TB).
I'm almost certainly only developing about 240ish at the fly but the base was the 200 kw small port head motor.
