Deer Killer Posted April 14, 2008 Share Posted April 14, 2008 No, I would think it is the other way around. The TGV cause restriction in the intake path and in turn causes back pressure on the turbo. Removing this restriction will cause the air to flow freely into the engine. So in turn there would need to be more boost pressure in the charge. Trust me there are/were no leaks. The boost reading up top(4800rpms) where the vf40 falls off was extactly the same. I thought you meant the inlet. MAF still shouldn't be wrong unless you're losing fuel due to too far advanced AVCS, or your latencies are wrong. Link to comment Share on other sites More sharing options...

rao Posted April 14, 2008 Share Posted April 14, 2008 Preadet, I don't know how to tell you this but your turbo inlet is RED Looks good. I really like the double catch cans Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
praedet Posted April 14, 2008 Author Share Posted April 14, 2008 T - nice job mounting up the catch can system - looks really clean.What mfgr was the cans again and do you have any concern about emptying above/onto the turbo/UP/DP location or do you have a plan for that? SBTAMW manufactures the catch cans. With the heat shield and a turbo blanket in place, the catch cans are getting warm, but still touchable Preadet, I don't know how to tell you this but your turbo inlet is RED Looks good. I really like the double catch cans Yea, it is red, I wish it was black:spin: Maybe now that I have done it before, I will rectify that situation in the future As much as it would have been easier to do a single one, the size of the inlet and outlet on the catch cans is such that I would be hard pressed to think the air will have fun if all the air from the PCV and the breather will make it through in a happy state (Aero-engineer term) Link to comment Share on other sites More sharing options...
LittleBlueGT Posted April 14, 2008 Share Posted April 14, 2008 Maf was about 3.5% off, 11.1 target vs. 11.5 measured.... Not how accurate it was, but how much air did you flow before and after? If your g/s went up 10 and your psi went down .5 psi that would be a good thing. Full tune of 68HTA, KSTech 73 MAF, Racer X FMIC and ID1000s................by the DataLog Mafia!!!

If your g/s went up 10 and your psi went down .5 psi that would be a good thing. I am honestly not seeing no increase in spool right now, actually seems a bit slower. I have logged full boost by 2700rpms vs a best of 2500 before. It is definately less "punchy" down low, I am going to start messing with the AVCS in the sub 3200rpm region. The g/s is exactly the same up until about 4200 where I gain about 5 more. On a larger turbo I could see the real benefits being above 4K....

Big difference, pulling timing all over the place. I am going to have to rework my IAT compensation tables. I got out a little early today while it was still under 75 degrees.

My car feels more powerful at lower rpm's without boost than ever. You simply shouldn't have to retune unless you've been pushed into load/maf ranges that were never tuned before.

You simply shouldn't have to retune unless you've been pushed into load/maf ranges that were never tuned before. May not make sense but it is fact I did change plugs(1 step colder), APS Inlet, TGV deletes and extended the intake down into the fender all at the same time so who knows. But I am having to basically start from scratch all over again. I did experimented with a bit of AVCS advance and it seemed to liven it up a bit down low. It really is too hot right now for anything, gonna get back to it later tonight. By the way what do you have your AVCS set at in the spoolup region?

Since load/etc is all derived from that, it is the problem. It's not anything else. I did TGV deletes, 1 step colder plugs, DW740 injectors, and didn't need to change the MAF, except for where I was running out of fuel at 99% IDC and increasing the MAF did nothing, but I didn't know that since people were going above 100% apparently "just fine" Link to comment Share on other sites More sharing options...
Infamous1 Posted April 16, 2008 Share Posted April 16, 2008 After further dialing in the butt dyno approves . Honestly spoolup has not changed, midrange feels a bit stronger and load is up accross the board. Had to go in and drop a bit of timing, I still think topend is where it shines brightest. However can't really say what affect the deletes had from the inlet pipe. Link to comment Share on other sites More sharing options...

If so do you have a fuel pump and what is your AFR target up top? Link to comment Share on other sites More sharing options...

Darkness of Death Posted May 7, 2008 Share Posted May 7, 2008 got a question about the TGV deletes - what happens to the ??sensors are they? on the sides of the TGV. are they just disconnected and taken off? Link to comment Share on other sites More sharing options...
Infamous1 Posted May 7, 2008 Share Posted May 7, 2008 The sensors stay on the TGV's, all that is left in the engine bay are the connectors. Link to comment Share on other sites More sharing options...
SeeeeeYa Posted May 8, 2008 Share Posted May 8, 2008 The sensors stay on the TGV's, all that is left in the engine bay are the connectors. Which, on my car, I cut back under the wrap, ends tucked invisibly away. Never will be used again, no need for connectors to clutter things up.

praedet Posted June 10, 2008 Author Share Posted June 10, 2008 Updating this, I know everyone is mainly concerned w/ power, but I will add more data to something I psted earlier in this thread... Yesterday, running 80 mph from C-Springs to Denver (about 60 miles) I got 31 mpg... This is a downhill run, but I have done it many times at the same speeds and traffic conditions. My best MPG was 27 mpg before the TGV deletes and APS Inlet. Yesterday w/ headwinds, it was 31mpg... I like the TGV deletes On the way back I got about 28, instead of 24 normally as I go up about 800 ft... Link to comment Share on other sites More sharing options...
BlackHole Posted June 11, 2008 Share Posted June 11, 2008 ^ Hmmm, I need to justify this purchase. TGV deletes are ~$180. With a 4mpg increase from the normal 24mpg I average going to/from Chicago and gas at $4/gal, they'll pay for themselves in 7560 miles.
