What about when you are at part throttle?

turbo05gt

Come on JR, Its not really helping to tell a guy that spent 2 weeks installing your kit "hey just pull it apart and send it back to me and Ill keep it for a week or so and maybe or maybe not find anything I can tell that s wrong with them" Maybe if you "cooked" a little better the other chefs would all stand back and watch. If the turbo spins freely and has no play what else could be wrong with it O might chef?

Granatelli

At part throttle, you would have no pressure at the turbo and a slight amount of vac at the manifold

Im really just trying to learn here but why does Tial tell you to run it that way?

Granatelli

That is a typical bash statement. It serves no purpose and assumes we would sit on his stuff. None of that is true. I have been hovering around here and speaking with Tom minutes after he emails or seconds after he calls. I commend Tom for wanting to learn and do it his way but he could have sent us the 3 parts when they first became an issue to him and we could have checked them all out. As for finding out if there is an issue - we won't know until I see the parts. Again I need to follow the facts. The facts are that Tom is the first guy that can't spool his turbo like we say the turbo should. I looked at is car and said it looked OK visually - so now it is time to send me stuff. He says he is sure the BOV and WG as fine so send me the turbo already and lets get this thing over

Hey I just pm'd you, all Im saying is that its easy to say "hey just pull them off and send them to me" for the average Joe. How much do you think it would be to ship all of those items, $75-$100 and it would take a week or so to get to you, how long will you need to get on things (I know how hard it is to drop everything and jump on problems like these) then a week back and another week to reinstall it all back on the car. So we are looking at having his car down another month. Its not at easy as it sounds. What if Tom sends you those parts and you find nothing wrong with them? Will you "allow" Tom to take off the entire kit and send it ALL back for a new kit?

Granatelli

We agreed to work on Tom's part the same day they came in. If the parts are bad we would replace them and pay the freight. There is no reason to exchange the entire kit, but if that is what it took I guess I would have no choice. exchanging a tube for a tube will change a thing but looking at the moving parts would go a long way towards it . Tom has said on several occassions had we not told him we thought it was lazy he would have been happy. So we brought this on ourselves

At the end of the day everyone can say or think what they want - we are still here trying to help him out and not saying it is what it is. People keep speculating and wondering why it did not make more power at 13psi. it was only there for a milisecond

turbo05gt

The power is there its only the spool (in my mind) that is an issue.

This is kinda like how happy you were the first time you got "lucky" and looking back on it how bad it actually was now that you know better, I think it will be much of the same here.

I'll say it one more time. Pressurizing the system should be your first course of action. It is a lot easier and less time-consuming than dismantling the system and returning it piecemeal. If nothing leaks, then you can start taking off parts. A visual inspection is not adequate. It needs to be functional. The fact remains you know in its current configuration your turbo develops at least 13 psi which is more than adequate to make tons of power. There is no reason to believe that it is going to make more horsepower at 13 psi with a boost controller connected than without one. Here is a possible scenario. If the turbo is spinning fast enough to make 25 psi then that is what the MAF sensor is telling the ECU. If half that pressure is being lost somewhere downstream of the compressor discharge the ECU, I believe, has no way of knowing this since it is not a speed-density system. That would account for the fact that even at 13 psi you are not making big power. This could also explain why your initial tune from Granatelli was so far off. In point of fact it may be that the tune was on the mark. However, if the system is leaking and you alter the tune to try and compensate you end up creating a mess.
As far as connecting the boost controller to both ports and having the boost run wild, that is ridiculous. As someone facetiously mentioned, a boost controller controls boost.

After this post, I'm not going to argue about this anymore.

1. Hose didn't come in the kit, so I asked you if I needed to buy regular vacuum hose.
2. You said not to hook it up.
3. Boost went to 13.4 psi.
4. You admitted you were wrong and said to hook it up.
5. I asked where? To the turbo?
6. You said it didn't matter, "there is no difference".

Guess what? Since Tial told me that by connecting the hose AFTER the throttle plate I could "run the risk of damaging the diaphragm", that kinda sounds like it does ****ing matter!

Your answer should not have been, "it doesn't matter at WOT". Your answer should have been, "it NEEDS to be hooked up BEFORE the throttle plate, PERIOD".

I would have hooked it up before the throttle plate.

That is true... I would have been dumb and happy. I would have had it dyno'd on a Dyno Jet and got something like 425 HP / 405 TQ. Would have seemed pretty good. Those numbers are with a de-tuned tune (since Scott pulled timing when he saw 13psi) and no line to the WG at all. Now I have a better tune and a way to keep boost to 8psi.

And I appreciate that. I just need some time here. It's the holidays. My wife is PO'd everyday at me since I spend so much time talking about this and writing on here. I have no time after work to actually DO anything.

Can I please get everything hooked up properly? Then have the car run with the new tune on a Dyno Jet?

Then we can look at the new chart and see if it's still crappy.

Maybe JR can slide some $$$ Scotts way to spend some serious time tuning your car when its all said and done.

This just seems to get worse and worse.
