99 R34Gtr Vspec, Now Stroked!

[bored33]

More for rotors in Windsor, GTR's in Girraween lol!!

Ohhhhh i see i see haha

[GTRsean]

Well just got back from Unigroup in Girraween over half an hour ago as they have been flat out!!

Long story short, no good. Found a split hose on the run, the one that goes from the "twin turbo" outlet past the airbox...GRRRR

So I'll need to fix that before a tune can be sorted...Well, I'll have to go back there tomorrow and get back in line once I fix it

[SiR_RB]

Oh dam I also split that hose going from the twin turbo pipe outlet, just replace with a hard pipe kit?

[bored33]

Yeah, just some nice cheap ones will even do as long as they are good quality. From memory, I'm pretty sure I had the exact same problem until I replaced it with a hard piping kit and even gained me some extra wasps.

[GTRsean]

Went with a cooling pro silicone black piping kit. Looks rough enough, and no more leak

Oil problem was a combination of rings not bedding in yet and lack of crankcase ventilation.

Once it was caned on the dyno blowby reduced very quickly. 312kw @ 16psi. 326 @18psi. Will go back in a couple of weeks for the power tune In the mean time it's Sau nats time

[bored33]

Good work! Just in time huh hahaha see you boys tonight.

[GTRsean]

Yay!!!......yawn...so tired!!!

[Piggaz]

What time do we have to be at snakefield?

[sinistaGTR]

nice work sean, be good to see the 'power' run results how different does it feel to drive compared to the 26

[GTRsean]

It doesn't need as many revs and putts around happily.

At the moment it's tuned to 312 on 16psi and 326 on 18.

Apparently these turbo's don't boogie till 24psi...

Soooooo time to boogie to 25

[bored33]

Not enough gate... not impressed

[NISSAN GTR]

Are you running HPI Dumps .

if so what front pipe you running to get good flow

Thanks mate .

[SiR_RB]

Dunno about Sean but with my HPI 3" dumps I got custom 3" to 3.5" front pipes made, couldn't find anything that big off the shelf

Custom pipes are the way to go , but aren't you still restricted by the turbo outlet ? Edited November 21, 2012 by NISSAN GTR

[GTRsean]

Mine are twin 3' into 3.5' front pipes as well with flex joint, then through a nismo metal cat.

Getting a 3.5 inch cat back stainless steel exhaust sorted out tomorrow as the HKS one is 3' from cat to 3.5 from the back of the resonator, then less than 3 inch through the rear cannon...

[Deano 1]

I made custom tuned legth front pipes for my car, 3inc into 4inch merge. Ill post a pic and more details tonite

[GTRsean]

4 inch would be the way to go or even twin 3 inch, how much can you squeeze the wallet

[r32-25t]

Twin 2.5 is good enough for 400rwkw on a 4L engine

[GTRsean]

But you got 4L of engine telling that gas where to go lol!!!! gas has got no choice

The cross-sectional area of a single 3.5" pipe is about 38 inch square. The cross-sectional area of the twin 2.5" pipes is about 39 inch square. That gives equivalent flow.

Likewise, the cross-sectional area of a single 4" pipe back to muffler is about 50 inch square. And the cross-sectional area of twin 3" pipes is about 56 inch square.
