Scott,

Were you having surging issues before you perfomed this mod?

Scott,

Were you having surging issues before you perfomed this mod?

No, not at all. There was some minor shuffle on light throttle, but it has always done that.

The reason I have made this mod is:

A, I am currently having my engine rebuilt with forged internals and I am hoping to see what you can get from stock, (Steel), turbos with all the extras, (Cams, Manifold, elbows, full exhaust etc etc).

B, I am an air inductions system designer by trade, and when I say the insides of that duct a cold shiver ran down my spine!

hmm, id like to try this on my car,, i get shuffle at going on an off throttle at light loads but more curious to see what it might do interms of power gains..im running Gt2860-5s at 1.6bar givin approx 600Fly BHP.. Would it improve things? Anyone got one I could try or sell to me?

 

[Scott]

Yes it would improve power, see graphs on the first page of this thread.

As for buying on, some in this thread said they had one.

Make sure you have balanced the wastegates properly first. Modifying this pipe is secondary.

I picked my car up from RK in the week after a complete engine rebuild, and no I am running it in. What I have found is there is no shuffle any more, which is good, mind you my missus was disappointed as she said she'd miss the chipmunk noise .

I am unable to report any power gains A, I am still running it in, B, there are a lot more mod now so from my cars previous configuration.

All in all, for a few hours work messing about in the garage, its a mod well worth doing.:thumbsup:

 

[kismetcapitan]

looks like I'm next in line to do this mod.

As i have 2 std turbo pipes I may give this a try also.
Mainly because I would like to run the ARC air-box I have which is impossible with the full HKS hard-pipe kit.
I may also swap out the massive HKS inter-cooler I have as Im running a stroked 2.8 with gtss's and dont think the huge pipes and cooler are going to help my search for instant response ! watch out for a for sale thread should this be the case.

[kismetcapitan]

massive intercooler? are you trying to tempt me out of this month's toy budget??

 

[Scott]

My advise is try to get the beginning of this baffle as curved as possible. It makes inserting the baffle more difficult with a curved slot, but the flow characteristics are much better then a flat plate. Ideally you'd want the outside of the bend as smooth as possible.

 

[chaz_r33_gtr]

Still up for trying this on my car but id need some one to make one first that i can they buy off them...Anyone planning on making a few?

 

[Scott]

Chaz,

Do it your self, its not hard.

First get the yellow pages and find a local welder, call them and confirm they can weld it back up again. Then, whip the pipe off in 5 mins and set to work with a hack saw knowing you've got a guy down the road who can weld it.

Either that or mark on your pipe where you want the baffle to go and I am sure the welder will do the lot for you for £50 or so.

Be brave!!!!!!!!!!!!!!!!!!

I know its not stock looking but I made two seperate stainless pipes merge into one them wrapped them in a water jacket which is fed by cool water pumped from a seperate rad up front. Still trying to perfect it to try and get a chargecooled effect before it hits the intercooler. Had some shuffle still so put a balance pipe between the outlets of the two turbos. Didnt expect it to work and was told it wouldnt but it did. No more shuffle! I have not has the car running enough (due to me making a **** up and junking the engine) to say it makes much difference but I will mess about with it some more to see if I can get a result. Worth a try.

 

[G40tee]

you will have yours back to you v soon ian, it is either going on the car tomorrow or monday.

 

[frostmotorsport]

hmm, I have my pipe off @ the mo for some maintenance - wondering if I should do this mod or not. Never had a shuffle problem.... what do (experienced) people think? worth the effort if shuffle isn't an issue?

 

[GT-R Glenn]

Frosty, its a piss easy mod, that gives 10hp atw takes 2 hours and reduces the possibility of shuffle.

!!

Need I go on ?

 

[frostmotorsport]

no! I shall start cutting tonight then!!
