This year I switched to a 72mm turbo aiming to hit 1k and while trying to tune it was starting to get wild fueling up top on the Carberry ROM. Turns out there is a compensation that isn't defined in the ROM that was playing with fueling that only gets worse on bigger builds.

As a result, I also ordered a Plug and play Haltech and started tuning that and learning a lot of the differences. LOVE the thing. The powerband is considerably smoother and flatter than I could ever make it on the stock ecu, particularly up top since fueling is now stable enough I could trust adding timing.

Was originally going to shoot for 50-52 psi but the car would not make more than 40 on the dyno. I believe this is related to the filter as I have had this turbo at 45+ at the track (even in lower gears) with the filter off. The filter isn't all that large and I was seeing some small-ish boost oscillations. I was thinking about taking the filter off on the dyno but the dyno just kicks up too much crap when the car goes into boost to trust it.

I'll get a new "downpipe" made to bumper exit the exhaust for whenever I try to put it on the dyno next so that the exhaust isn't pointing down into the dyno to kick stuff up.

Going to the track for a full weekend in two weeks so we will see what she runs and we will see how things go. Going to bring spare transfer gears, hah.

Bullseye!!!

I will be checking on nasioc just to see results of how it works at the track when its turned up...


Impressions vs the old 67 fmw so far? I remember screaming bullseye all the time like a year ago and I will feel like a pos if you hate the turbo lol.

Haha. So far it makes pretty good power and look forward to when I can take the filter off and see what she'll do on the dyno. I was really trying to hit 1k, but we'll see if both the turbo and I have it in us. I really only think that is possible if the filter (or something else) is really holding it back even at the current boost level. Could even be my tuning, I wouldn't write that completely out of the equation.

It is pretty loud, but other than that it's street manners are really not bad once you get use to driving the triple plate.

Car weighs around 2750-2780 without me in the car and I know I have a bunch more weight I can take out if I put forth a little effort.

I was about to say you're mad revving a 2.6 to 8500, but then I saw it's an overbore rather than a stroker.

Drag car I presume? Any pictures?

I drive it on the street, it is plated and insured so it is kind of a street/drag car. It is loud, but manageable, so pretty much I just avoid driving through neighborhoods as much as possible and other than that have not had any issues.

Old turbo - new turbo is in the same location, just a 72mm batmowheel instead of a 67mm Borg Warner billet.




Engine bay - I am a function over form guy so it isn't particularly pretty, but it works.




Probably my favorite picture for the car from Daean Chase:

+1 for the haltech, I love my plug n play, runs smoother then the oem ecu and so many features and options with it. Nice build as well.
