Got Over 400kw Atw?

[Marko R1]

ive heard the same feedback as well jez.

as they say - good news travels BUT bad news travels faster.

Dajae - I bought a pierburg but haven't fitted it yet...I created a thread on my findings and what I can tell you is that it flows more than the aeromotive stealth by a decent margin but I can't recall the figures exactly.

As a comparison, Bosch 044 flows 200ltrs/min @ 5bar whereas the pierburg flows 360ltrs/min @ 5bar.

They are not cheap so expect to pay about $450 with a filter.

The pierburg pumps only flow around 300l/min @5bar which makes them just shy of supplying 6x 1000cc injectors. For 6x 1000cc injectors I would still prefer to run two dw300 pumps at a base pressure of 4 bar. That way you can switch the second pump at higher load.

They take alot of meat out of the block to fit the 3.4 stroker. Have heard of a few blocks not holding up for long.

Have u tested one before?

Only what i have been told never seen

lol..

Well i did the prep work to our block for the 3.4 and the amount you remove isnt much at all. About a 0.080" chamfer at the base of bores which is more precautionary then neccesary and the oil pick up tube needs about 0.060"-0.080" to allow for stretch so the rod bolt head doesnt hit the tube wall on the first three cylinders. That is all the clearancing required. Its pretty basic and nothing overly critical to block integrity.

I will take a picture to show.

As you can see, its not alot of work to do and your not really removing much material.

Rumours are always good for a laugh

Considering you have removed way more than you actually need to Mike those rumors are a bloody joke.

[r33_racer]

Lol yeh I do go overboard a little sometimes.

[DVS JEZ]

Thats the problem with chinese whispers.

Thanks for showing the truth

[The Dan]

What about the oil gallery.

How much more before you bust through into the hole?

[r33_racer]

Cant remember off the top of my head. I can check it tonight and see. Im guessing you mean the oil pick up gallery thats in the picture?

Yeah.

I understand you probably won't be using it due to a dry sump setup but for the regular folk it would be interesting to know how deep they need to go into that gallery wall

[r33_racer]

Dan,did some crude measuring with the vernier and it seems the wall thickness is about 4.5mm. I took off 2mm(0.080") so you would be left with 2.5mm wall in the relieved section. However if you did the regular 1.5mm (0.060") clearance you would have 3mm or thereabouts.

Decided it was time i did some proper port matching on the twins and open up the exits of the manifold while i was there. Looks like it payed off i went from 405rwkw to 430 on 1 psi less boost using 98octane at 23psi. Check out how flat my boost curve is.

[Marko R1]

Fantastic result and great back to back comparison

25kw increase due to porting

[Ryan1200]

Closer inspection was almost identical boost pressure but only 395kw on this particular run. I ran 131mph on 395kw so will see in a few weeks if it turns in mph.. Changes that could account for the gains were opening up stock manifolds and port matching everything. Removing unused 02 sensors from the very small split dump entries. Repairing front turbo outlet pipe which was squashed after i got to it with a hammer to make some clearance from the rocker cover due to a miss allignment of the front compressor housing and i CBF pulling the turbo off.. So bring on willowbank i can finally start working on getting my times down without getting asked to leave every visit..

[Piggaz]

I am assuming you're using standard manifolds Ryan?

Great result!

[r33_racer]

That is a great result! Always good to see the difference of before and after when doing basic changes.

[Lithium]

Thats pretty sweet, cheers for sharing that - it shows that being pedantic about the little things really can make a difference between a "happy" and "not so happy" similar setup equivalent.

[Piggaz]

^^

Attention to detail definitely is key here. The -5 results range from 320 to 450 kw plus for example. It ain't quite as simple as 'chucking on a set of snail, turning up the boost and BOOM, fantastic result'

[luke gtr]

Soon my prettys, hopefully, very soon....

[Moodles2]

Goes to show it's worth port matching the stock manifolds to the turbos, and here I was laughed at in a recent thread when I mentioned doing it in 350kw+ applications.
