Project Tial650 S4 complete...

Re: Project Tial650 S4 complete...

I had already taken some logs and knew what the car was doing before I ran it against the A6. I also knew that the ECU still had the same tune that the car was running before the motor popped, which was a very safe tune.

Re: Project Tial650 S4 complete...

If this car feels that much stronger are you going to turn up the boost from 25 psi? I bet you the owner is happy to see that there car is coming along good. When I get back to canada I am starting the 605 build with my bro I would like to run these 2 cars together to see what the difference is like.

Re: Project Tial650 S4 complete...

At the altitude we're running these cars at, you're approaching a compression ratio of 2:1 when you get into boost pressures higher than 25psi, which just generates way too much heat. The pistons in these motors are Mahle forged pistons, yet they still melt when cylinder temp and pressure is too high for too long.

This car will be tuned for a nice, safe 23-24psi hold to redline.

The motor break-in tune that I was running ramped boost up immediately to 17psi, and then ran off of the WG pressure, which was 14-15psi.

All in good time, my friend, all in good time.

Re: Project Tial650 S4 complete...

Well we just got finished pulling the motor out nof my brother's car and I am hoping that the 605 are in by the end of the weekend

How is the 650 car coming along is it going to be ready soon???

Re: Project Tial650 S4 complete...

Soon. We're installing a catch can this morning, since the spike in crank case pressure popped the PCV valve when the motor seized. We'll do one or two final touch-ups, and then we're just waiting on VAST to get us a few more revisions of the tune, and she'll be finished.

Re: Project Tial650 S4 complete...

We just got a base file for the 605 and the car is running pretty strong!! How goes the battle with the 650 car??

Re: Project Tial650 S4 complete...

Catch can is installed, tweaks are finished, just waiting on VAST to send more revisions of the tune. We need to be writing our own tunes. This would have been done a week or two ago, but VAST is super busy these days.

hey j. do you know what u'll be writing ur own tunes with yet?

Re: Project Tial650 S4 complete...

Entertaining a couple of options, but haven't finalized one way or the other yet. I'll keep you in the loop as we move along.

Re: Project Tial650 S4 complete...

Well, we still have a LOT of work to do with this tune, but here is where we sit right now, after moving from the break-in tune to the base tune +1. Running 20 psi to redline, and very conservative timing.

Re: Project Tial650 S4 complete...

Well we finished the 605 car and are ready to do some pulls against the 650 car. How is it coming along?

Re: Project Tial650 S4 complete...

What other supporting mods do you have on the 605?

I dont imagine the comparison being all that close...you should be looking for a well running K04 car... or K04 on race or meth

Re: Project Tial650 S4 complete...

Coming along nicely. We're still in the process of getting the tune dialed in just right.
