bet that spools like a mother hubbard. :D

Lee said full boost by 4500rpm :)

 

What's that at the flywheel?

 

 

:D joke!

 

Nice power Johnny you big nimrod. Looking forward to seeing it first-hand.

It'll be 639bhp ;)

You can admire from afar ;)

That's a lot of power at low boost.

 

What tq did you so?

I don't know the torque - but Dan is going to email over the dyno plot. Jamie is there, he reckons there's another 100bhp to be had with a 4" pipe, it's sounding strangled. So I guess it's 4".

Bloody Hell!! :D spool machine at only 1.4bar too.

 

great result! little 3" must be a disappointment?

 

Nah. It's a road car, quiet that I can use for civilised driving - and roar away when needed. Nothing is stressed and no ridiculous boost.

Nice result - congrats.

 

What was the reason for keeping the boost at 1.4bar?

 

The exhaust, bud. Ryan didn't want to up it anymore - probably diminishing returns. There's fuel and turbo capacity for a lot, lot more. Just need to decide about exhausts now - and evaluate the 4" options.

Good result, good spool, should be an awesome road / track day car!Would have been intersting to see pre and post turbine pressures as well as boost. Needs more sensors and a proper ecu ;)

Yea - am out of inputs now on the Syvecs, I need the channel expander - soon!! As for road car - we'll see when I get it back. Might be best to go 3.5" or 4" exhaust?!

there is only one option, Boostlogic :cool:

 

Well done with those results, with that spool it's going to be a very rapid road car.

Aye. Boostlogic might be a bit loud for me. Whifbitz twinbox 4" could be an option, though.

In old money, and up until about 6 weeks ago, it would have been 751 fwhp.

 

great numbers JG :)

Cheers mate. I'm just sticking with 638rhhp!
