No, because I lack the tools to do it myself. Have asked my tuner for a rough quote, but I really don't like paying others to work on my car so haven't had it done yet.

I have checked for leaks without much success, but I'll check again. Plenum is definitely sealing. Intercooler has 1psi drop across the core, exhaust has been dropped before the cat with only a 2hp gain. Not sure about exhaust temp, tuner didn't mention anything. Cam timing is my suspicion as I was getting surge coming up the back hill at Barbagallo in 2nd/3rd with about 60% throttle.

Hey all, I am currently trying to sort out some issues with my cars power, was just after some input from people in the know about what may be holding me back, as I have had some conflicting advice. I apologize in advance for the length of this post, I just want to explain everything clearly. Little bit of background for those that don't know, these are my current modifications: Link G4 Plug-In ECU Greddy Profec B-Spec II EBC externally gated Hypergear ATR43 G3 Turbosmart Compgate40 1000cc Injector Dynamics injectors Plazmaman FFP Plazmaman 72mm throttle body JJR 3" bellmouth dump/front pipe VENOM 5" 100 cell cat 3" custom Kermit Engineering exhaust Walbro GSS-342 in-tank fuel pump GReddy FMIC Splitfire coilpacks HKS fuel rail Sard FPR Performance Springs valve springs and retainers Tomei Type-B Poncams Headtorque custom bronze valve guides ARP head studs. Now with those modifications, here is the result from my last tune: The blue line is my low boost setting at 16psi, the redline is my high boost setting at 18psi. As you can see from the curves, there is bugger all difference in power between these two settings. It is the same story with any boost higher than 16psi, it makes the same power at 16/18/20/23psi. So on that evidence, it certainly appears as though I have a restriction somewhere. Now my tuners comments when he tuned the car were as such: He also mentioned that he thinks the standard exhaust manifold is definitely a restriction, but he has tuned cars with the stock manifold to over 300rwkw and has had 3 other cars with the same turbo as me but less modifications make around 295rwkw. So he doesn't believe that is my current problem. That is all well and good, I was going to work through that list and get the car back to him. However, I took the car to my mate and local custom piping guru, Kermit. Kermit has an excellent reputation here for his work, and he has a good understanding of fluid dynamics and how to design pipework to get the best flow. His input on the matter was that yes, my pipework could be a little bit better and it's probably costing me a little bit of power. BUT, he doesn't think it can be made a LOT better, and he certainly can't see it holding me back 50hp. Maybe 15hp at most. He said he is willing to do it for me, but he doesn't want me to spend what may cost over a grand in custom pipework to only make an additional 20-or-so hp. SO. I just wanted some input. My current pipework is 2.5", and has a number of 90 degree bends. However it doesn't step down in size, it is all 2.5" except where it goes to 3" at the throttle body. Here is my cold side piping: Does anyone think that it would be worth redoing all my piping? Keeping in mind that the cold pipe can't really follow another path, any custom pipework would require those same bends. Or am I better off looking at the cam timing or elsewhere? Thanks a lot, Martin.

Yeh I think Luke's and my trap results are very effected by boost response between gears. Took the car for a drive the other night and tested that out, and I've got about half a second to a full second of lag between each gear change.

Should also mention I've tried every theme. None of them show the embedded videos.

Sorry if I've missed it guys, been reading through the latest threads here but haven't seen it mentioned. What's going in with video embedding? Using my mobile (Android), I can't see embedded videos using either the Full Version or the Mobile Version of the site. Posts containing an embedded video are just big blank empty posts.

Can confirm ^ I didn't have the Full Version button at the bottom for the last few days either, just got it back today.

Wishful thinking lol.

Course ya can

Yeh get flanges put on it man. My exhaust guy gets his mild steel 3" flanges for $6 or something. The number of times I've taken my exhaust off, I would've set the car on fire if the exhaust didn't come off in sections.

Yeh I wouldn't be too concerned about 5-10kw dude. That's nothing. Go take it to the drags and see what trap speed you can get (I don't think the results you got from the airfield are very accurate, otherwise you definitely have nothing to worry about!). If you get anything close to my 108mph, then come back and we can cry together

Well I don't see why the WA section being shut down means people need to buy from over east, it doesn't. It just means you need to look in the national section to find stuff, which is easy anyway. Doesn't really change anything, just makes it a little bit harder to find stuff. Learn to use the search function.

If you're using the stock fuel rail then use the stock fuel pressure reg and just get the right size injectors.

Eh, thread got gay. I'm now switching to Team ARTZ. Let's go team!

How do you purchase the wrong silicon joiner? Their measurements are for internal diameter, so unless your intake pipe has like 5mm walls then a 3" joiner should go onto a 3" pipe just fine.

Have had the same issue with my dads brand new $40000 Honda Insight. Immaculate paint totally ruined. Still haven't told my dad OP, did you end up contacting Aggroman?

What method did you use to do this man? I should really have a better look at mine.

I would put the sensor just before the fuel rail so you know what temperature the fuel is when it gets to the engine. Knowing what it is pre-cooler doesn't help much?

I used gutter mesh from burnings for mine. Looks way better than that shit at supercheap.

Got it through the group buy on here. It arrived like November last year, so no chance of a refund. Cost $140 or something, but oh well. Might make my own at some stage.

Ha! Obvs meant 1/2. Stop hating on me Nick. You're always hating.

Yes. You need less rare fractions and more common fractions. Try 2/1 and 1/4.

Come on mate. No need to bullshit everyone.
