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

/Lasse

...and the turbo is in the car..

the last pic is the best!

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.

installed the diff yesterday,

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

some backup!

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.... :/

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.

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?

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...
