looks like its coming along real nice.

I got them from a local shop here in sweden!

you should be able to find equal in your country...

or else i could send you some bends :lol:

Looking really good Gustav! Now we will have 2 more wastegates marks on the floor in the dyno room:lol: Not to speak about the sound when the 2 opens:icon_tup: Should be a nice hearing for the neighbours:Wconfused

/Lasse

looks great! but one question, why is the one dump tube going up and over the other when it looks like it could just go down? or is the subframe in the way?

Yes there was no room for it to go the same way.

I will take a picture when its on the car, then you'll see :)

Looks great! even better IRL! =)

update? :D

most of it is finished, got all the parts on coating now, because of christmas and new year everything takes extra time :hahaha:

within a few weeks ill get her on the dyno and then we'll see how much boost i dare to run :lol:

gaaah... can't make up my mind whether to make a new 4" full exhaust or staying with my old 3".... feels wrong to stay 3" but i don't want to make my ears bleed more than they do when im out criusing..


What to do?

i've done a couple full 4" exhaust on bridgeports and it really wasn't that bad! :D

as long as there are no exhaust leaks and the muffler exit a little past the bumper it wont resonate and drone inside the car. Outside..... that's another story but who cares!?!?!?!! hahaha

Great lookin project you got goin there!!! Makes me wanna get out and work on mine....now if i can just get some money to finish it :( lol

Cant wait to see how your setup works. I've got a very similar setup ;) I mean....VERY similar!!

You need to finish that thing!!!!

Yeah 09 is the year for sure ;) Its only been like 10 or something!! haha I've been too busy messin with the quad and Rhino lately :)

What type of welder are you using? what brand?

Also what kind of TB are you using? I love your welding, and your setup is godlike to me. I hope to build my car just like you did :)

Thanks man!

I can't deny that i got the weldon setup idea's from your project, i hope you don't mind :)

wow, kind words! thank you!

I'm using a 200amp ac/dc welder, china brand for a couple of hundred bucks.. been working for 2 years now.

i just had to polish it :wallbash: :lol:

hopefully i'll get back all parts by friday.

Looking good Gus!

Yes, I agree that it seems wrong to choke the 4" down to 3". If you want to maintain the surface area of a 4" pipe without all the noise, consider running a pair of 3" pipes. The area will be slightly more so you'll have similar flow (or better), and the noise reduction will be better than you can achieve with a 4" pipe.

Did you polish that yourself or have it professionally done?

It looks great!

Chris

no no, i don't have the patience for that.. it was done by a local polishing guy, it took him 3 hours :icon_tup:

Not at all :) now i know why it looks so familiar :D I can't wait to see how it turns out being that we're so similar.

Finally i got my stuff back!

hopefully i get to start her by tomorrow night :)

Hehee...i be watching you Gus when you flick the switch of your "little" monster:hahaha: Hope it sounds really mean:) Then we go to the dynoroom and make some numbers:Wconfused Looks good anyway:icon_tup:

...and the turbo is in the car.. :)

the last pic is the best!

Yay, first startup.
 

Yepp today was a good day, got to hear some rotary sound at last!

nice man, car look's badass! good luck

looking good.. cant wait to see some dyno numbers.

if you dont mind, can you post any pics of the inside of your UIM?

Thanks guys,

im going to install my new diff and fabricate a 4inch exhaust, then it's time for dyno :)

here ya go.
http://www.molnsatra.se/bil/uim.JPG

The diff installed
 

installed the diff yesterday,

to get the job done you need the right tools..

some backup! :hahaha:

pure excellence

Awesome work Gus!

Hey Gus which throttle body is that?

thanks guys,

it is a noname 80mm throttlebody.

so many forklifts LOL!!! i love it!

just did some dyno pulls and the car put down 595whp@22-22.5psi, peak hp at 7160rpm, having some problems with boost, it wont hold up.

Ill post some logs for you when i get home and maybe some of you gurus can help me out :)

i just passed 100+ dyno pulls with this engine :)

Ok, here are a log from one pull.
green line = boost (in bar)
red line = backpressure (in bar)

As you see im losing boost... is the backpressure causing this?
im using the small valve seats (28mm) and their 60lb/inch spring (the hardest one)
It is set up like this (http://synapseengineering.com/smf/in...d57&topic=97.0

Im also using a HKS HVC (IV) boost controller, i can't say im very familiar with it.

Oh, im still one the 3" exhaust.... :/
http://www.molnsatra.se/bil/152bar.jpg

I don't have any experience with your wastegates so i have no clue about them...

I would try disconnecting them and setup some sort of boost limit on your ecu or stay very alert and watch the boost and see if you can get more boost without it falling off..

I don't believe you have to much backpressure. you have roughly 28psi back pressure with 22.5psi boost. That's not bad at all...

Thanks for input..

i've got some more combinations to try on the wastegates, they've got some kind of internal boostcontrol letting you choose different ports for different boost. Ill try the highest setting and just run it on the springs..

please post up what you find out with the differant combinations on the gate as I am running the same and getting ready to turn the boost up for tuning....

595 at 22psi.. Nice she is on her way ! Cant wait to see the 30psi pull. 675hp I hope woot :)

Sent a mail to synapse, got a fast reply.

"Gustav, sounds like you are overwastegating. I'll look at the logs when I get back to the office.

Peter

Sent from my iPhone"

i guess this means that the valves can't keep closed?

I had a feeling your wastegates were the problem...

better boost today but the turbo went bye bye.............. whats next?

like your brand new turbo went out?

Yes, something like that....

i got big endplay in all directions so my guess is bearing failure?

the question is... i have one more unit, is it worth trying? :scratch:

Hmm appears to be losing boost at the end of the pull. Does appear to be backpressure maybe blowing the gate open. Does your unit have the 96mm turbine wheel and 1.32A/R housing?? Most of the cars I have worked on with that turbo don't have much of a problem. Also have you got a restrictor on the oil inlet on the turbo?? I have worked on 2 FD's running Borg 475's that ran restrictors...killed the turbos less then 100 miles. Borg's like plenty of oil...
