Just wondering what kinda power people think the n/a twin cam could produce while staying street friendly???

Is jmm developing something for these?

I would assume there is a bit of power ready to be unlocked with cam changes and aftermarket management to allow intake and exhaust to act independently.

Ive just read about a guy getting 6.55 to 100kph in an xr6 n/a manual (im surprised!) with a standard engine.

Thanx guys,
Pete

It would be interesting to know...Cause stock its about 7.7 to 100kph so surely you could get it in the low 6's...
Exhaust / cam etc

7.7 is pretty damn quick for a 1600kg STOCK base model car 0-100

Well the BA 6 likes to rev harder than the old 4.0L and given DOHC + extra valves setup and the fact people can (if they have the $$$) get 250kw out of the old donk, you'd think you could get around 300kw out of the new lump. Be a very nervous engine though.

Street friendly?

I dunno, should be able to coax 220-230kw out of it and still retain some manners.

One thing Ford have said is that the VCT on the intake and exhaust are fixed to the same settings.

By actually adding the software to the EEC to give you variation between the two you'd get more efficiency and power, but they haven't bothered to do that yet. IIRC it was because the additional code would require an EEC upgrade or something.

I'm sure it will be looked at once Holden bring out the HFV6 though.

Ok here is my assumptions: With a decent extractor/exhaust your looking at 15-20kw + computer tuning/piggy back computer another 10kw it's not hard to see 220kw out of the BA DOHC engine. Not sure about the 6.55 0-100km/h as the weight is a critical factor in 0-100km/h acceleration. I'd like to see a stock manual BA XR6 tested first.

Cant wait to see the aftermarket get to it first JR!

Ive just seen an xr6 n/a ute with 230 odd rwhp which takes it to about 230fwkw(?). Heres the link. http://www.cardomain.com/id/xr6ute

Hasnt even touched cams or aftermarket chip

:)

Jah_Nix

i have just about finished sorting a 300kw n/a set up for the sohc i6

so i'd dare say 320-350kw would be the limit of the dohc i6.

cheers.joe.
