popping my modding cherry!

[zymotic]

Gonna get my first mods tommorrow <----------- NEWB

Twin dump pipe 3 inch from turbo mild steel to stainless tip via

Jack Beedhams @ Redcliffe +

El Cheapo Turbosmart bleed valve set at somewhere between 10 -12 psi.

Weathers hot up here may go for just 10...

$1250 all up. Should notice bit of a difference eh? Maybe 20 rwkw..

Wonder how loud it will be, not too loud mehopes.

[sammus]

sounds good

[sweetr33]

depends on how many mufflers i guess, if u got one it will sound just nice. 2 is abit quiet. U will definitely notice a big difference in power gains. With full exhaust and more boost. Be careful...

[junkie13]

i haeard the gfb bleed valve is better then the turbosmart one as they dont spike but confirm that with your installer

Ditto.And they are available at most autobarns

[zymotic]

cars in the workshop atm. Just called them about GFB bleed they dont carry them. He said that most peeps happy with the turbosmart said its the new model. He also said that most bleed valves spike under heavy load anyways.

Oh well time will tell. Oh and when u guys say spiking Im guessing u mean something like when u give it a good amount of throttle at high revs/under load that the turbo tends to stutter sort of like a blocked carb or something? Forgive my newbness but not sure exactly what that means...

[junkie13]

spike means you set at 0.8 bar and on a cold night it might spike to 1.0 bar io found that to be bad because it can be dangerous thats why my s15 is wrapped around a pole few months back

Ok just drove it for the first time. Yep boost comes quicker and harder @ 11psi. Gave it a bit nowhere near redline (not game yet) and can definately notice more power guess with the twin dump full 3inch and 11 psi Id be around the 160 rwkw mark now.

But man is it loud. Anybody got any ideas on what sort of sound proofing i can put in my boot. The compliancers wont give me my spare so its empty and probably making it more noisy! Thinking some kind of foam needs to be light and block noise really well...

how was the service? i get everything done there and they are always very good to deal with!

Service was fine, spoke to Bob Beedham he just recently sold his 33 so he new what i was after. Only added extra $50 for twin instead of single dump. Happy as plus 2 year warranty. Just need to make it quieter.

What have u had done there?

[51OOO]

yeha i spoke to both bobby and jack,jack is often at my work so i get things a lil cheaper,but even if i did not, I would still take my car there! and i live at JINDALEE!

have not had the car too long but have had a full 3 inch with high flow cat big muffler ect,timing belt and 100.000 service( jusT had it earlier to be safe..) tHEY KNOW WHAT THEY ARE TALKING ABOUT,and i find theya re generally nice people!

what is twin dump pipe?? This another way of saying screamer pipe?

[akeenan]

twin dump = another pipe for wastegate, re enters dump futher down....

The compliancers wont give me my spare

I would have thought a car which was complianced and no spare wheel in the boot unroadworthy.... I would go down and force them to give it to you..

Yes not happy about that but they told me those were the rules and yes they gave me a roadworthy to take to QLD Transport without spare...

Oh by the way anybody got any ideas on soundproofing for my boot. I think im getting fair amount of resonance from the exhuast tip through the boot. Thinking of going to clark rubber and getting some foam to put in behind the back seat to dampen the droning.

[sweetr33]

not sure if spare wheel is a roadworthy item. There is a weird way of thinking behind some roadworthy laws. Common sense doesnt always provail

[akeenan]

im pretty sure they check the spare wheel for pressure and for the amount of tread... maybe things have changed

[WLD747]

By having a twin dump pipe does the heat / gases leave the wastgate quicker thus increasing power quicker?

[V8skylineMAN]

Qld Transport says that you dont need a spare for a roadworthy, but if you DO have one, it has to be in roadworthy condition....
