so as im sure many here know the BAE setup, just a simple but awesome non intercooled setup. problem is that im running into power loss when it hot out and i drive for a bit.
ive been debating adding an intercooler, but with the design of this kit doesnt really allow for that as the turbo outlet and intake inlet are about 1 inch from each other. ive also debated a meth injection setup to help keep these EGTs cooler and keep the power on these hot days, but i cant find much info on people running meth on IDIs.
any hints or ideas would be great, im just getting sick of the EGTs im hitting, and sick of the powerloss when things heat up.
i can tell how much more fun this thing would be when i have a cold day or night, this thing screams under those conditions.
Thanks
the setup

Damn nice car. Ditch the intake and problem solved on intake routing.
The whole setup was originally a gas car thing anyway right? Non-intercooled and a few psi was no big thang to them! lol
-
i have a gasser intake that has had all of the ports closed up and a gutted g60 tb on the end for 2.5" piping and coupler.
i must just be crazy but there isnt much room for an intercooler, if anything ill have to find a small one to sit on the passenger side pocket by the alt.

Also, I am sure that EXTREMELY hot air intake system is really killing it for you too. It HAS to go. The worst spot for an air filter on a performance build.
-
mine i played with from 96-02 was same thing....
it only makes max 7psi.. no ic needed... not enough boost to require it.. not like there is a wastegate... yea it way oversized... but man when i thits it pushes you in the seat unlike a stock td..
-
Rerouting your turbo intake will help dramatically. U can do water meth easily woth an pld windshield washer bottle and pump and inject it preturbo with a carb jet or what ever u want
-
Where is your timing belt cover and oil pressure sender at? Also agree with the guys saying relocate the air cleaner.

Mine actually boosts quite a bit higher, as a .22 rayjay off a later arkay turbo. i can hit 12ish :)
as for the air filter relocation, i agree it needs to be moved. just undecided as to where right now. thinking the raintray but i don't want to cut into the car.

i havent tracked down a belt cover yet, was missing when i originally got the car. as as for the pressure sender, it died and was temporarily replaced with that lovely bolt. and yes i plan to get another, along with a new gauge.

I have been driving these diesels for 5 years now, and never have I had a timing belt cover on them. All covers are off, makes a timing belt a dream-job lol. I'm also not an idiot, and I do not drive over debris..

I hope you never experience a failure. Here even driving 100% pavement you could see a failure as at any second a groundhog could run across the road and his head get caught in your TB. Anything, another belt get behind it and wear down.
You can have good luck as 8v did, but I would go the safe route as rebuilds aren't cheap :D
-
Meh, maybe. The only open spot the the timing belt is really between the pump and cam, and a little bit between the cam and crank.
The V-belts weren't ever covered by anything, don't see them breaking all over the place lol
-
The v belts don't have to stay in time, and the timing belt doesn't need to break. I had a V belt jump off my a/c compressor and eat a hole into the TB cover on one of these. I had to replace the Timing belt as it was almost ready to break when I caught it. If I wouldn't have had the cover the engine would have been dead. I use them as the cover isn't the bad part of the TB job I don't think.
-
Well... I got lucky last week: my alternator belt decided to exit the engine bay and tried to take the WP belt with it. The WP belt flipped over but stayed on the pulleys until I got home. :-/
TB cover is essential in my book.

That is a sick Mk1 jetta. What suspension setup are you running?
Yeah, an intercooler would be nice. You could potentially work with what you've got if you reclocked the compressor housing, but it's hard to say, really. You would probably benefit from a gasser intake manifold. And of course, relocating the air filter further forward, away from all that exhaust manifold heat.
I don't know much about methanol injection, but I can't imagine that for our diesels that it's that much removed from what gasser guys are using?
It all depends on what you're willing/able to do. Piping kits and/or fabrication will make a world of difference for you. Please post pics of your final setup.
-
ordered some piping so i can redo the intake. went out and looked at my options, thinking routing to the raintray will be the easiest and best solution to get away from the heat... hey i have a scoop for a reason right :D :D
as for the awic stuff, it sounds like i great idea. just need to play around to see if i can get piping routed right.

Car is on custom valved RLs, actually rides quite well.

FWIW I think you could add the CIS intake and then run the inlet to the turbo to the area behind the grill. In between the battery and rad if possible, that way you wouldn't have to cut your rain tray up.
Looking at your intake I don't like its design much more than the factory TD one...which could be another option.
-
if its a rayjay like mine.. to reclock is cake.. 1 v band style clamp..
and 8v manifold should fit..
turn turbo towards firewall and mani of choise..
bet that is a nice kick in arss if it hits as hard as 7 psi did.. but does it hit as hard? had lots of lag.. 3k till it hit.. id almost bet on my toaster it would break the tires free like a 930... at 3000rpm..
-
i had the standard bae rayjay on and it hit pretty hard, but with this it hits just as hard but earlier :)
comparison of both of the turbos i have, im running the arkay right now as the bigger one lagged too much..

New intake setup, and yeah a cut a hole in the raintray, i figure the intake and hood scoop are now functional.

and got the boost gauge installed finally:)
not bad peak boost for dialed back fuel screw and BAE kit :)

Did you couple it at the raintray?? or is it a pipe that moves with the engine?
-
It moves with the engine but I've given it enough room to wiggle and not make noise. I also added a seal around where the cuts were made.
-
I'd replace that breather with a CDR valve and draft tube before it makes a mess.
-
I actually just came back in the house from the garage. That's exactly what I was messing around with.
I just need to find a way to tap back into the intake stream now.
-
90 off of the VC, and thread a nipple fitting in that intake tube. Is it thick enough to get a thread or two of grab?
-
If you can't get a thread to grab on your pcv bung you install in the intake pipe, just use a thin bolt behind it and seal around the threads with sealant.
I'm also another proponent of AWIC. Mount it over your trans where you have room. Go with a core that does both pipes on one side, run the 8v gasser mani, and you can run minimal charge piping. Your turbo orientation is actually oriented near-perfect for this setup. What's your exhaust piping diameter?
P.S.: Love your wheels; ATS classics are my dream wheel set. I don't do staggered, however; like to rotate the tires so I'd run spacers in back.
