8bit's Mk1 Leon Cupra R. Scarlett - as in Johansson...

[csd_19]

I've had a nosy and it was the idle spring for the FMDV004 valve I saw at £5

Just remembered seeing a spring at bargain basement prices!

 

[J@mes W]

Blue spring has solved my fluttering.

Awesome i'm assuming it drives better, feels stronger etc.. as a result?

@ 8bit - Gave the car a proper spanking last night, all the in the name of research of course. It's vastly improved in the lower gears 3rd and 4th but i can feel it bottle necking in 5th and 6th, this i think is the standard exhaust holding it back.

Hopefully this will be fixed once the TBE is fitted, just need to save up for a FMIC.

I'm very tempted to try the blue spring though, as i'll need one for stage 2 anyway. Kind of a no brainer really.

Nice one, cheers for that Gonzo Is yours staying put on the adaptor better this time round?

Borrowed a pressure tester off Yohan this evening so am going to pressure test my hoses and stuff before giving the car any more stick, popping boost hoses is not cool. Also need to try and suss out where my flat spot at about 3500rpm is coming from. It's not the B5 TIP as that's off the car for now.

If the blue spring doesn't solve it then I'll try knocking the timing back a bit with the Revo SPS, but TBH I can't see it being that as I'm getting zero CFs. I can take out the Creations boost hoses and put back the OEM ones and see if that sorts it. Failing all of that then I'm stumped, it didn't do that before I had it mapped but I can't remember when I first noticed it and I've done a few things to the car since then.

Want to sort these niggles before refitting the B5 TIP so I can tell the effects that has in isolation. Certainly missing the extra midrange pull of the big TIP a bit right now tho...

 

[8bit]

So after work I swapped out the Creations upper boost hoses back to the OEM rubber ones to see if that helped things any. The good news is the big flat spot at about 3.5k is gone and so are the various little ones elsewhere in the range, so I guess the kink in the second hose was causing that. The bad news is that the car definitely feels a little less eager to spool and rev now so I'll be ordering a set of the SFS boost hoses on Awesome's special offer this week.

Other negative is that there's still a bit of a noise when on full boost from low RPM in 4th. I can't see it being the DV now as I've got a blue spring currently in my 008 so not sure what that's about. May take a look at the turbo to charge pipe hose.

In other news, I replaced the cup holder in the center console as my original one had broken, and also the button on the B-pillar to disable the interior alarm sensor as mine had the actual button missing. Simple things but then simple things please simple minds and all that

Going to have one more go at the B5 TIP on Wednesday, with some help this time courtesy of csd_19. Fingers crossed

Nice one.

I was under my car at the weekend and have 2x massive kinks in my I/C pipework so that will have to get sorted this year.

Any luck with the pressure test?

 

[8bit]

I couldn't get the tester into my boost hose so I decided just to swap them back to the OEM hoses and see if that helped. I'll get your tester back to you whenever is convenient for you, I remember you saying you were away this weekend so will catch you next week sometime, cheers anyway though

Yeah I think we can conclude that kinks in pipework/hoses are bad, not that this will be news to anyone! Just a thought - Wallace Performance could probably make up some custom hard pipes to fit your car out of alloy?

 

[Deleted member 35798]

That's a shame, no way it will go on at all?

Ya I'm down in Glasgow this weekend.

They probably could, will need to get a price from them. I'm currently reading about cores etc on audi sport so it might be time for an upgrade this summer.

 

[8bit]

The outer diameter of the pressure head was slightly larger than even the outer diameter of my hose! I guess i could maybe have stretched it but didn't want to, partly because I didn't know if that would stretch it permanently (and make it less secure if I refitted the hose) and partly cos I was reasonably sure that taking the hoses off would help my power delivery. Which it did

I'm not going to put those Creations hoses back on the car now anyway, stock ones back on for now. I'll maybe pressure test it once I get my SFS boost hoses but that'll be a few weeks away yet so I'll get your stuff back to you soon.

EDIT - I'll have to pick your brains on the cooler stuff too

OK, update time

Last night we (i.e. me and csd_19, thanks again mate!) got the B5 v2 TIP fitted again. Better this time in that we got the coolant pipes bent out the way so the TIP is now all the way on to the adaptor. After about a 10 mile drive at speed over some dual carriageways and bumpy roads it seems that the TIP has not yet moved on the adaptor so fingers crossed that's OK.

However there is still a bit of a kink on the bottom bend due to the angles involved, even with the TIP rotated backwards towards the bulkhead it doesn't line up well with the heatshield. Hopefully I'll be able to do some logs soon and check airflow. I'm out in the car again tonight, if it stays put then I'll keep it for now and keep an eye on it. If I'm going to keep it long term then I'll take it off again and trim the ports and MAF end down a touch more just for a slightly better fit.

Going to order those SFS boost hoses today I think. Realised last night you can feel the difference between OEM and uprated ones - the OEM ones are rubber and will "balloon" when they fill up with charge air. At one point I went on WOT in 4th, the car took off, couple of seconds later it got faster again That's nice but I'd rather just have bigger diameter pipes in the first place, plenty of space for loads of air.

Drive home was good fun, Craig, cheers again for your help

Hey mate would it fit better if you took a little more off the MAF end? how much have you chopped off?

 

[8bit]

About 1.5 inch. Don't think that'll help the kink at the bottom, that's happening because the MAF end of the TIP is pointing downwards compared to the heatshield. When I said I might trim it a bit more it's cos the cone filter is now a bit of a tight fit inside the heatshield. We'll see tho, I'm happy to be proved wrong

How's yours fitting now, any better?

 

[dreago 1]

It fits better however there is still the kink at the bottom which im hopeing taking another inch off will help. In the last week i have been using it to get to work, about 40 mile round trip and it has moved off the billet by about 3 mm at the bottom. so the onther inch off should help, have been highly reluctnat to give it some stick.

Anytime Niall, no problem

Was fun to be out in a mapped stock turbo car again, feels strong on boost.

Just thinking - if you're trying to get rid of that lower kink you'd be better taking a bit off the turbo end of the hose instead of the MAF end - how much do you have to play with again?

 

[8bit]

Cheers min Was out for a blast last night, once it had warmed up properly it was even more eager.

I'm pretty sure there's no real scope for trimming the bottom end but I'll take another look. If I get time, weather and can be arsed at the weekend I'll take it off to trim the other bits a touch more and have a proper look then.

 

[dreago 1]

Hey mate has your TIP moved off the adaptor at all?

 

[8bit]

Only managed to do maybe 50 miles since refitting it so not sure yet, not that I can tell so far. I'll keep an eye on it over the next few days and post back, will be using the car a little bit this week.

I think the key with those jubilees is to make sure they're sitting nice and flat on the silicone. If you're using the ones that Bill supplies then they have quite a wide band so it's quite easy to have them sitting slightly lop sided, so to speak. I tightened mine up a bit at a time, making sure it was still sitting nice and flat on the silicone, then doing a bit more, give it a bit of a wiggle to make sure it's still flat, tighten some more, until it's done up right.

Of course if its' still kinked badly then that'll put pressure on the area that fits over the adaptor. Mine is still kinked a bit, not as bad as it was but a little bit. I found that rotating it backwards towards the bulkhead as you look at the turbo from the passenger side of the car helped a bit but it's still not a great fit with my heatshield.

Just for info, not long after I refitted mine to ensure the hard pipe was out the way, I did over 600 miles to essex and back and mine never moved and still hasn't, so as stated if the jubilee is sitting right then you should'nt have a problem.

 

[dreago 1]

ok, thanks. I am very tempted to have a little redesign of the heatshield. which heatsheild do you have? keep me posted. thanks.

 

[RDS]

Mines a home made job, its the only way

 

[8bit]

ok, thanks. I am very tempted to have a little redesign of the heatshield. which heatsheild do you have? keep me posted. thanks.

I've got the Jabbasport one mate.
