Have a MkII XR8 with 6 speed.

These are my dyno results:

Stock                                                      198.5

Dual 3" Di Fillpo Exhaust & Headers          210.5

UniChip                                                  223.5

Car is brand new and with those mods should be good for 230 - 235RWKW when it gets a few K's on it.

Underdrive pullies go on next week which should add 7 - 10 RWKW. I also put a "T" snorkel on with a K & N Filter.

Di Fillipo system is fantastic...sounds real nice 

Cheers

Yeh, but does it go any faster? 400m measure HP best!

Don't understand what you are getting at ..Does it go any faster than what ??

Goes a hell of a lot harder than my series 3 XR8.

If you dont mind me asking what sort of costs were you up for xr8888?

Also what does the under drive kit do?

Would love to see the shot of the quads from underneath.

Sounds like another happy camper

I've got a set of pulleys for sale, check for sale section of FF. Great mod, probably one of the best.

What I meant was, does it go any faster than before or is just noisier and thirstier and only goes faster cause you wallet is lighter?

I reckon a diff ratio change would yield better performance.

rednut once the underdrive pulleys are in it will be pulling around 300fwkw so I dont really get the question of whether it is faster or not of course it would be, I think your question should ask whether it was good value or not.also if anything it will definately be better on fuel with a less restrictive exhaust and apparently the underdrive pulleys will help too. I am thinking seriously about the undedrive pulleys as well

also 'theone' boss motors do react well to mods (and mileage) I have only simple mods but it pulls much harder than when I bought it. of course it does not have anywhre near the bang for your buck potential of the t though

Great work xr8888

Excellent mods!

Love the Xr8 Go the buldge

XR888,

You wouldn't happen to have a sound recording of your car with that exhaust system? I am looking to get a GT and do the same thing with those quad exhausts. Looks awesome I hope is sounds as good as it looks.

Mate if you PM me your email address I will send you 2 sound files of 1.5mb each.

I can also send you a little video also.
