remap gave 8.5% more air flow/what bhp gains ????

[007 VXR]

the fish changed the cats and vxr 04 headers to wortec ones .
now iam told the engine is breathing 8.5% better ..but what is that going to give in extra bhp
car is 6.0vxr (56) and has hh122 s/c and wortec cai,remap .??

I went from cast manifold to Wortec headers on an 05VXR with a HH112 and got a whole extra 20ftlbs torque and no extra ponys.
It just happened earlier and steeper, so it felt much stronger though.

BTW



It was the traction control cutting in.........

It should be related directly to power at that point it was measured.

Too bad you didn't develop that capability a few weeks earlier.

the fish recons my pistons should be ok at this power level .but no more till i do the internals

What psi you running the charger at?

yep ..roger at the fish said no more power for me till internals are done next summer

but that dont stop me saving some weight!! looking at carbon fibre bonnet and carbon seats ....and weightwatchers

[after_shock]

Be interested to know what weight saving options you can do, was discussing it a while back but not many options seemed to be on the cards without replacing exisiting parts with mega expensive bespoke items!

[007 VXR]

can save alot with the wheels poss 5/7kg per corner for about 1.5k
seats about 20kg for 1.4k
still waiting for weight on bonnet but prob about 20kg for arond 1.1k

As I say mega expensive bespoke parts lol, getting onto 5k worths of stuff including fitting which to me is a massive amount of cash for the weight saving potential.

Alternative end of the scale, take out the spare wheel, never put more than £7.50 of fuel in it, make sure the washer bottle is empty similar weight saving for no cash haha

By replacing body parts with carbon fibre does it effect the safety of the car?? You know like in an accident??

Body panels do virtually nothing in an accident its the supporting structures underneath that do all the work!

true .. my the boy is putting on weight to

wheels are the biggest saving...so iam told , if you save 20kgs of unsprung weight..that works out the same as 80kgs internal weight

[after_shock]

Yeah very true on the wheels, always remember on my old Volvo had std 17' BBS alloys that didnt weigh much, bought a set of 19's for it mail order and they weighed an absolute ton, totally destroyed the handling of the car!
