Ran the 4-banger tonight at the track.

[nissanfanatic]

I went out to test the new setup. For those of you who don't know:

old setup:
Revhard unported, T04B

New setup:
Groundzero manifold, T3/T04E 50trim w/.63ar

I am running 2 psi less on the new setup. Tonight I was touching 10psi, but it was exceptionally cold tonight. Usually its at 9psi.

On the second run, I pulled 1% fuel from 4000rpm on.

These timeslips only included 1/4 ET and 1/4 trap speed. My track featured a 60's series race which means NO amber bulbs, stage and then GREEN. Needless to say, it wasn't much of a "test and tune" night NTM street cars were poo-ons all night.

1st run:

Notes: Launched okay by feel. Pretty sure I was spinning a little. Second gear I slipped the clutch way too long in order to keep from spinning. I obviously overdid that and ended up shortshifting to 3rd. I also shifted into 5th which was also a mistake.

2nd run:

Notes: Launched like it was my first time ever drag racing.lol Spun first way too long(I'm glad they didn't include a 60' here). I then missed second. After that, I drove it pretty well(not too hard from here.lol) I didn't shift to 5th this time, so I now know that 5th isn't required yet.

I won both races. First was a restored chevelle. Beat him hole-shot. Second was some old school vert. No idea what kind of car. But he pulled me off the line, and when I missed second. When I hit third, I began to gain on him and right before the line, I passed him pretty fast.

All in all, a decent night.

nice bro !!! 13.7 nice!
have some q dough...
why did u lower the boost? and did u down-side from a T04 to a T03/T04? and what is a 1% fuel ?

[nissanfanatic]

yea. I actually did a 13.404 on my last setup.

Lowered boost because the GroundZero manifold is a lot less restrictive so more power at the same boost level. I didn't get a re-tune and wanted to be safe that I wasn't going to knock or anything. Turns out all is good, so Apexi AVC-R is next.

No, my T04E actually flows more than my old T04B. When I get my camera working again, I'll post a pic of the two side by side. The T04E is significantly bigger. Plus exhaust side of my new turbo is tangenal as opposed to my previous oncenter housing. So efficiency+x there.

-1% means I took out 1% airflow voltage AKA leaned it out a little bit. Expirmenting.

Laggy? haha hardly. I thought my old turbo was responsive enough... This turbo spools fucking fast. IDK who even needs GTs. I can crack the wastegate in 1st easily....

It is efficient to approx 430whp on the KA. IDK on the SR.

IDk on boost. It woudl be different on the SR than on the KA and woudl aslo depend on your setup.

External. Turbonetics Evolution 35mm. Open to atmosphere. Yes its loud.
