WGT Dynopack

[20B_boy]

Either way, I dont think the \'18%\' loss is much to go by. The 18% loss that gets banded about was determined from the FDUK rolling road day on a Dyno Dynamics chassis dyno back in 2002(?) by looking at 2 stock RX7\'s and comparing their measured wheel output with what their manufacturers FWHP was quoted as being. Also, the hub figure is going to reflect less drivetrain loss than the wheel figure - a big lump of metal and rubber takes some turning!

surely if it\'s 18% loss you should divide by 82 then multiply by 100 to get what it is at fly so 354+ ponies?
Si (dunno about the power stuff but i am a statistics freak http://www.smileycentral.com/?partner=ZSzeb008_ZNxdm46052GB\' target=\'_blank\'>http://smileys.smileycentral.com/cat/3/3_3_1v.gif\' border=0>)

you\'re probably right, statisitcs is not my strong point it must be said.

Looking good, so how much $$$ are we talking for a session on the rollers and a full map?

Cheers,

Saw your car on Friday James, looking good buddy.
I was up at Pips all day on Friday having a load of work done. A big thanks to Pip and Dave for all your help.
What a place to break down, literally 30 yards from Pips door.

Anyway main reason for my post is talking to Dave they think their Dynopack is reading figures lower than what they should be. Apparently cars they\'ve put on their old setup are now recording lower figures on the Dynopack.

Mine seemed to follow this trend. If you remeber I got 286bhp at the Nobles RR day. Since then I\'ve had it decatted, downpipes, bigger injectors, bigger fuel pump and Apexi ecu fitted. All mapped properley by Pip and now putting out 297bhp.

Thanks Rich,is that a flywheel figure or at the wheels?

I\'ve never been a fan of traditional rolling roads but these hub Dynos are the way forward,closest thing to an engine Dyno without getting too complex.Dave said the same thing,they think it\'s under reading by as much as 20%.Mine actually made more power on the twins than a single turbo they had on a few days before.

Feels a fair bit quicker than my 20B Cosmo did on it\'s fresh engine and the Cossy was no slouch above a tonne!

Sorry for a slightly misleading post.
The Noble day figures were recorded at the flywheel and Pip\'s at the hubs.

That said Dave still thought it was recording lower figures.

I\'m just more impressed with the sound now its got a proper zorst on. Great fun setting car and bus alarms off :rollin

Have you opened a can of worms there James....lol

Who needs single turbo eh ! :rollin

Hmmmmm

You got a proper figure yet big man? http://www.smileycentral.com/?partner=ZSzeb008_ZNxdm46052GB\' target=\'_blank\'>http://smileys.smileycentral.com/cat/4/4_2_105.gif\' border=0>

Same ol story different machine-:reallymad Guys these ARE for tuning not pub talk figures:confused: I\'m sure you will find no matter where in the UK / world you go, you will get different numbers, be happy you have a healthy car/ engine THAT  has been tuned by an EXPERT, only way you guys will see who is producing the best figures is all to turn up the same day on the same machine :spank

Hope not Rich!:)

When it eventually goes pop I will get Pip to port the engine and fit a Garrett GT35/40 kit,single is the way to go if you want BIG power.

Only 1 question for me James....

Can we have more pics of your car !!! Looks awesome. I do like the Gram Lights front bumper.
