Got Over 400kw Atw?

^ Thats what I thought too, though I was quickly corrected..

At what point did the dump pipe become a hold back? I didn't expect to hear that, it must have been a huge amount of power!

Not really Lith. seeing 3 lb of pressure in the dump at around 5000 rpm. Bit pissed off with my piper atm. when we had the 35r on the car he built a 4 inch dump. now we have the 37/88 he goes and shoves a 3&1/2 inch pipe on it.

I mentioned it to him at the time but he seemed to think it would'nt matter. WRONG!.

He's getting a visit this morning.

Oh! and for what its worth Lith it cranked out 530 hp @ 17 lb.

So the new dump pipe will be finished today? You gonna kick his arse for the stupid downgrade mate?

I would say no chance until at least next week mike. I will be voicing my displeasure. A day lost, 3 hours of dyno time, full tank of e85 all for no result. Not happy Jan,

[Lithium]

Whoa well that sounds like a solid start... bummer it hasn't gone as smooth as you'd have liked so far, but still pretty promising. Look forward to hearing how it goes with the new pipe!

[SimonR32]

Fail! 3&1/2 inch dump is restricting. New dump on the way. Do it all again.

sigh....

Is the gate plumbed back into the dump?

[r33_racer]

At a guess, considering noels hate for screamers, I would say its safe to assume it is.

[SimonR32]

Makes sense then

[HYPED6]

Its funny. 18 months ago we would be cheering. 530 on 17 wow what a machiene!

Now its....... stupid engine...... only making homo mid 500's. on under 20 pound of boost. I mean really, why even bother.

Normally people start at 20 pound, not finish there.

Not really, 5 years ago we were making 520rwhp on 17psi using BP98 with T04Z's

[Marko R1]

20years ago ppl were quoting hp figures haha

then again, hp no's sound more impressive than kw no's

You win the prize.

You mean you have a dyno sheet that says 520rwhp on 17psi with a T04Z.

3 different dynos... 2 different cars?

[HYPED6]

520 is a stout effort for 17 pound. What engine may i ask?

We have commodores that run 145mph with 590rwhp. Maybe the dyno was having an off day,

[mico]

i make 550whp @18psi, 1.06/ex gt35 bp98. stock long motor but guess what it is

LS1?

[Beer Baron]

nah I'm going to say falcon straight 6...

[mico]

yeah youre right mate, my beloved bf ute i should have also said stock turb, fundamentally

[DR 32R]

Having been driving an F6, I've often wished it was an easily transplanted engine. 4 litres helps spooling and off boost.

[Super_Dude]

I was going to run a 3 1/2 dump with my efr8374 but now you have me conisdering upping it to 4.

Exhaust if full 4 inch oval with a straight thru muffler and a side exit.
