Thread: 10:1 CR DE with bolt-ons dyno

I did little upgrade for local hillclimb racing car (Nissan Sunny 2.0 GTi). Its basic setup, nothing new...

Thinner line (old setup):
10:1 CR SR20DE
Custom header 4-2-1
~50mm exhaust
Kind of chipped ECU (maybe old rally Gr. N ecu by NME)
Modified intake

Thicker line (new setup):
10:1 CR SR20DE
SSAC 2.5" header
70mm exhuast
Nistune ECU with base .bin
JWT S4 cams
Custom 3" CAI (HotShot replica), Velocity stack with JWT filter
Thermoblok spacers
P11 SR20DE MAF
Fidanza 8.5lbs flywheel
UR pulleys

Numbers : 184 ps / 197 Nm That was with base map in ECU and timing wasnt set right. I bet there is 5+ hp left.

well done pal, thats great results

Crankshaft power or at the wheels?

looking good! wished my powerband held up like yours.

lol..... http://www.sr20-forum.com/offtopic/22801-dash-english-lesson.html

what are you talking about?

great results what was you're timing ? ? ?

Thanks guys.

Its crank numbers. Powerband hold pretty good to 8000rpm. Problem is long geared stock transmission, rpm falls a lot.

I dont know what timing is set to. They didnt had light gun and Consult while dynoing.. thas sucks, i know. But they will set it later and we will see if it runs better.

151whp without tuning? thats good going

what are the cam settings for S4, i found to get more power with cam gears but i'm with higher CR 11.5-12:1
