hi folks!

my s2 is running 244bhp 18psi on a hybrid t3 i have a baily twin piston valve which is starting to anoy me.
is it safe to remove my dv without without destroying my turbo and what i need to do.

cheers lewis.

244bhp at 18psi??

You sure?

Yes, take the DV off. No worries there.

why would that be hard to beleive?im runnin 214@wheels(240ish@fly) on 17.2 psi(got the graph to prove it)
anyway lewis's car is g? rst,which iirc has a very good spec to it,steel rods etc

lewis take the dump valve off mate,i took mine off,best mod i ever did

i second that with 230 at 16psi

As my car has evolved on its current build it's made

199bhp @ 18psi SCA (Fast Ford shootout about 2½ years ago)
248bhp @ 25psi at PTS (RSOC day 18 months ago)
256bhp @ 24psi at SCC (August 2006)

Have to agree with Christian and say 244bhp @ 18psi seems a smidge optimistic

File the DV in the spares drawer.

i found that leaving it on simply allowed the times between wheelspin to shorten as i wasnt losing as much boost between changes

makes a good noise though when you tap off

take it off , no problem.blank the pressure line and the adaptor off

well tbh the car was rolling roaded down south so power figs are prob a bit over as to what we'd see up in scotland,but as to say that 240bhp cant be acheived with boost pressures as little as 18 psi

anyway,heres 240ish bhp on 18psi

Oranoco

What's it being rolling roaded down South have to do with anything at all?

Your powergraph seems to indicate a peak boost of about 22psi, assuming I'm reading it correctly as it's not too clear

Chuck it away/make an ashtray out of it!

Ditch the valve lewis, you know it makes sense

Mines is in the boot

Look at this link and the graph will be clearer

214@ wheels with 18psi

P3 = Boost pressure

cars tend top make a bit less up here in scotland than they do down south from the variation in rr's,anyway thats another story.

yes my graph does indicate a peak of 22psi,i make peak power 214(wheels) with 18psi of boost,just like lewis makes his peak power off 244(fly) with 18psi of boost,i dont know what lewis peaks at prob 20+psi

the dump valve is going. my car is going for a rr after xmas for the first time thats not power enginering. will look out my last graph and try get it on here.

cheers.
