Amonje123 Posted November 4, 2015 Report Share Posted November 4, 2015 So I finally dynoed my car today just wanted to post them up here and check some things out. I made 206hp 203torq at 7psi spiked to 9psi and it made power all the way to 6k. I ran 15psi spike to 18psi I made 262hp 317torq but the car stopped making power at 4500rpm it just flat lined and lost power after 5500. The guy said that my plugs are gapped to big. There at 35 he said put them at 25. I'm running br7es plugs. I'll post a link to the graph. Here's the 7psi http://s924.photobucket.com/user/austinmonje/media/Mobile%20Uploads/Screenshot_2015-11-03-20-04-36_zps567lgdul.png.html?sort=3&o=1 Here's 15psi http://s924.photobucket.com/user/austinmonje/media/Mobile%20Uploads/Screenshot_2015-11-03-20-04-41_zpszq9f7ot3.png.html?sort=3&o=0 Link to comment Share on other sites More sharing options...

IntercooledFlatty Posted November 4, 2015 Report Share Posted November 4, 2015 no diode on the 86 ecu ? Link to comment Share on other sites More sharing options...
Amonje123 Posted November 4, 2015 Author Report Share Posted November 4, 2015 Yes there is a diode in the ecu to block the map sensor but it was leaning out my afr after 13 14psi when I had a 16g on it at the time. So I unplugged the map and it fixed my problem. That was a couple years ago. Link to comment Share on other sites More sharing options...
88351wtsi Posted November 4, 2015 Report Share Posted November 4, 2015 Good numbers. Sounds very streetable too Link to comment Share on other sites More sharing options...
Amonje123 Posted November 4, 2015 Author Report Share Posted November 4, 2015 Yea it pulls good. My question is should I gap the plugs down like the tuner said?He said my car should be putting down 280 290hp with 15psi not 260. I was thinking that's a lot of power I was lucky with 260 at 15psi. Most people I see here has more mods then me and only 260hp with 20psi with the 16g 17c turbo. Did I just get lucky?Thanks for all the replys.

IntercooledFlatty Posted November 4, 2015 Report Share Posted November 4, 2015 260 at the wheels sounds pretty good to me with what ya working with i'd say crank the boost to 20 and go for it ! Link to comment Share on other sites More sharing options...
Funky Phil Posted November 4, 2015 Report Share Posted November 4, 2015 (edited) Unless your blowing the spark out (miss fire) while boosting, theres no reason to regap. I agree with Harry, those are good numbers for the mods. What was the A/F during the pull? If its a little rich (safe) youll give up a couple HP. If your detonating the computer will pull ignition timing and youll lose somemore HP. Id leave it where its at. Good job Edited November 4, 2015 by Funky Phil Link to comment Share on other sites More sharing options...
Funky Phil Posted November 4, 2015 Report Share Posted November 4, 2015 (edited) Sorry, missed the links.High boost pull is pretty lean at peak tq. Rich up top Edited November 4, 2015 by Funky Phil Link to comment Share on other sites More sharing options...
Amonje123 Posted November 4, 2015 Author Report Share Posted November 4, 2015 I've had it on 20psi plenty of times just didn't run it on the dyno cause of what the guy told me about the plug gap. Car moves on 20psi but has the same problem when I hit 5k rpm that's it no more power. It's that how these turbos are out of stream at that rpm or is it a spark gap problem?

Funky Phil Posted November 4, 2015 Report Share Posted November 4, 2015 (edited) gap will cause a miss. I missed that your on MAFT. TD06 turbine should be plenty. Looks laggy on the graph. Is it that slow to spool on the street? Edited November 4, 2015 by Funky Phil Link to comment Share on other sites More sharing options...
Amonje123 Posted November 4, 2015 Author Report Share Posted November 4, 2015 It does spool a Lil slow in my option on the street I hit 15psi at around 3200rpm but the car won't start to pull hard till after 3500. Then the boost will spike to like 18psi or so at 4k rpm and drop back down to 15psi at 5k rpms. I'll be home in a couple hrs so I'll post the pic of the boost pressure,rpm,hp,torque, afr all that good stuff. Link to comment Share on other sites More sharing options...

Amonje123 Posted November 5, 2015 Author Report Share Posted November 5, 2015 So I just drove the car and it doesn't match the graph right my boost does hit 15psi at around 3200 not 3800 like the graph shows.Also the graph show my afr at 13 at 4k rpm during the boost spike at 18psi. That's not right. My wideband hits 10.8-11.3 immediately once I start making boost. So which gauges are correct? Thanks for all the replays Link to comment Share on other sites More sharing options...
Funky Phil Posted November 5, 2015 Report Share Posted November 5, 2015 Look at your AFR saw a 13.0AFR @ 18psi note in there. Link to comment Share on other sites More sharing options...

G54Bstore Posted November 5, 2015 Report Share Posted November 5, 2015 (edited) Maybe it's reading more on the conservative side? Idk not shabby by no means Edited November 5, 2015 by G54Bstore Link to comment Share on other sites More sharing options...
Amonje123 Posted November 5, 2015 Author Report Share Posted November 5, 2015 Yea I know that was a good run. But my question is why is my power falling off after 4500rpm is that how it suppose to be or can I fixed something here? My last setup felt faster. Only difference was the maf was a blow threw instead of before the turbo like it is now. Also I had a custom made log manifold with a t3 flange and external wastegate dumping to the floor. My butt dyno said it was faster and pulled to 5500rpm but no dyno to know for sure. I just know I shifted my old set after 5500rpm and with this set up I shift before 5500rpm.

speedyquest Posted November 5, 2015 Report Share Posted November 5, 2015 I think the answer is pretty simple. Your older setup flowed better. I imagine your tapering off is due to it not being able to breath as easily. Link to comment Share on other sites More sharing options...
screemin eagle Posted November 6, 2015 Report Share Posted November 6, 2015 Maybe it's knocking and pulling some timing out from it going lean on spool up. Link to comment Share on other sites More sharing options...
