2v quest for power

Still can't figure out why it won't make any boost. So going to go over things one more time.

But I think I'm ready to tear down for the winter. Get it ready for a cage, rear end and put the fuel injection on.

Make boost? Im a tad turbo dumb. I understand the boost part but why would it not make it?

 

[lwarrior1016]

Is that a fuel injection eddy intake?

How do you have the injector ports blocked off?

 

[punched281]

Idk why but the turbo just won't spool. I'll take it for a drive and it'll spool, then the next day it won't spool anything. Maybe timing issue? Maybe the turbo is bad but I doubt that as it is a quality piece from forced inductions.


Yes the intake is fuel injection, but I'll be going with the fitech go efi 8 boost ready. Good for 1200hp and about 20psi. Pretty sweet system

What did you do to block off the injector holes in the intake?

Drilled and tapped the holes

They shouldve been already drilled and tapped for the injectors, what did you do to cap them. An s475 is a big turbo, and takes forever to spool up. Yea you van make big boost but if its not starting to spool till 4k rpm, you dont have a long range for it to create its potential. Id go smaller but thats me. You can still hit 20 lbs and then some on a smaller turbo that starts to spool much sooner.

Yea, they weren't tapped. Yea it's a little bigger. Its from forced induction and has an 83mm exhaust wheel and 1.1 t4.

When it does run pretty well it spools alright. It is slow but it spools just fine. So something else is going on I think.

I have my on3 turbo still, could slap that on there ans see if it makes a difference.

I would slap on your old turbo to rule out any turbo issues. Have you checked for any clamps/v-bands/weld leaks that could be causing the spool issue?

 

[Nighttrain]

Check all your rubber boots too. Sometimes you can get an intermittent leak depending on how they flex. Youll lose your boost there too.
My point with the turbo size is you can hit just as much boost but with a turbo that spools faster.

 

[punched281]

This week I'll go through all that I think. Change out the turbo and make sure it's not bad or anything dumb.

Yea I'll double check all that too. Good point. Just gotta hit the basics.

Yea I know, but I just bought the turbo and can't really afford to just switch out turbos like that. I trust what forced inductions recommend and have seen others use this turbo. And I have a feeling I have another motor in the near future maybe more fit for this turbo. Ive also got a Nitrous kit on the shelf so I'll put that back on if the turbo really does take that long to spool.

 

[punched281]

Alright guys, I believe I found the issue! I think the carb needed a little help but that wasn't causing the whole issue. I think the crank sensor was messed up. So got that solved and the ignition was putting in waaayyyyy too much timing. So got a new timing curve in there and now it spools.

The turbo is smoking a bit which worries me a little and my oil pressure is at like 25psi when the motor is idling at 800rpm.

Hopefully some track times before the summer is over!

 

[punched281]

ordered up some fuel injection so that will start next weekend, pretty stoked about it.

 

[Nighttrain]

Sweet...

 

[punched281]

Sweet...

I hear ya about the turbo size on your last post. but there have been other similar builds with no issues. And on top of that my wife would strangle me for getting a different turbo right after this one haha

 

[Nighttrain]

Hey its all good....thats what we have them for, take the slack outta the leash hehe!

 

[punched281]

haha man, I'm lucky and she gives me a lot of slack so gotta behave!

she just let me order an efi kit for the car!

 

[Nighttrain]

Haaaawhat! Nah its all good, if i could go back in time.....wouldnt change a thing

 

[punched281]

me neither, it's been pretty awesome going through different things with my wife. And she still supports my car habits. In fact I feel her car will be pushed to get finished pretty soon. Now that we have a kid she is talking about an old wagon or Lincoln to use as a cruiser.
