definitely raw! But i prefer the sound of the turbo whine pre-open wastegate... but not at the expense of losing power by routing it into the DP... I'll get a in car vid and drive-by next week :LOL

so hows the car turning out this week bro.... any more progress?

 

Slowly going forward. I have to block the stock FPR that is on the tank insert somehow. I have to tie up the wiring that is tested and working.

So far I have had the car running for like 10minutes on idle with E85 and the new injectors and my new fuelpump setup. Getting the engine heated up abit and getting some air out of the coolant system. There are some more small things I have to fix, the car is still standing on axlestands and not yet ready to put down.

What worries me abit is the sound from the turbo, I will let a friend of mine listen to it and see what his verdict is. He is very experienced with turbos of all kinds.
Hopefully testdrive and some "home tuning" soon with a wideband sensor, just to get a clue of what the minimum charge pressure is of my manifold at high rpms.
When everything is OK for calm driving I will fix all the loose ends, change clutch and go to the tuner. Thats far away still tho.

THe exhaust sounds very promising btw

 

wow im glad to hear it.... i cant wait to see it finished bro... almost there.

 

can you give a run down on what you have done to your fuel system to run e85?

 

Most of the stuff can be found in this thread I think.

In short:

Drilled holes in the rail and welded returnline connection(s) to it.
Changed to ID1000 injectors.
Bought a adjustable FPR.
Made a hole in the tank insert and installed a connection for the returnline.
Installed the returnline hose from fuelrail to FPR to tankinsert.
Changed fuelpump to a walbro 255 gss342
Pulled separate wiring from the battery to the walbro pump. 4mm2 (11gauge)
The stock fuelpump circuit is pulling the relay on the separate wiring.
Thats basically it so far.

To be done:
Plug the stock FPR that sits on the tank insert to make sure the aftermarket FPR controls the pressure in the system. So that the injectors see the same ΔP regardless of charge pressure.

 

my 30R spools so loud thats basically all you hear. I love it more than you know, i love the 30R so much. Only turbo I would ever sell this for is a ported shroud GT35R...to keep the spoolup sound. what a ricer i am.....

 

we all have our times lol....

 

A small update on the project.
Testdrove the car today with assistance from my friend. He brought his wideband and we added fuel for the E85 map. The reason for the testdrive was to get the car to run safely on the rich side just to test the manifolds boost creep. We got some missfires at high revs but got the car to charge all the way up to around 8krpm. The WG spring opens and boost stays around 7,25psi, the highest boost we saw was 8,7psi. Possibly it will creep slightly more when going all the way to 9krpm without missfires, but I consider the test as a step forward. I think this manifold will work, I will just use the boostcontrol and regulate ~10-12psi all across the rpm range. Should be above any boost creep.

Reason for the missfires is unknown, I had the stock plugs in the car for this test, didn't wanna kill the iridiums incase the car ran too rich.
Also had some occational check engine light when idling, it was idling too lean at first. Don't know if that was related. I had no obd2 scanner to read the code today.

Next step will be to change clutch and try to get the car to the tuner.
Today we experienced clutch slip, don't know if its because the stock clutch only ran for 13 miles so far, Anyhow it felt like the power was coming on very strong already from low chargepressures. Maybe the manifold is efficient. I hope so.

 

man o man almost there.... hope everything turns out as good as it seems to be.... good luck bro... get some vids at the tuner if you can k.
