Sr20ve, sr16 cams, sr16n1 pistons (notched 0.050),WAI, CGears +2.5in & -5Ex, Fidanza flywheel and Payu's Ecu.

Nice. WP pulley could give a pony or two. What header are you running? What rpm are you popping onto the motherlobes?

Nice, now throw in bigger cams.

at 4800, I'm going to start saving for the N1's

great.

what compression you get with those n1 pistons?

What octane do you run/tune on?

Peace

Have u tried switching the intake and exhaust at different times?

Have you try others cam gears setup ? Ans i presure that you put them this ways to gain up there instead of some torque ?

Am i right ?

Thanks

That's what I thought. I had mine there when I first had my 16VE cams. When I dynoed it proved what a friend of mine said "Pop them @5100". It would seem to be especially true in your case as you have the cam gears adjusted with more overlap (?) I am assuming. Did you play with the RPM setting at all?

no I left it at 4800 because it seemed pretty linear, but I have to raise it a little on the track for better 60ft times:D

Usually the thing to do is take three pulls. One with cams off. One with cams kicking on very low, and then set at the point where the curves cross and do a third pull to confirm it. I mean I get it about the 60' times but you can go and get an MSD 2-stage to help with that.

I mean compression as in 11:1 or 12:1.

Know the 20ve come with 10.3:1, but with the n1 pistons in the 20ve block, what is it now?

Thanks.

I also think you should try cam switch at 5100rpm. That was where i got best results, in terms of usable power. This was dyno proven.

Maybe 12:1 I really don't know how to make those calculations

Great Project :biggthump

i need to take mine to the dyno soon, what header and exhaust are you using???

I think it's an OBX header bougth it a few years ago, and it has a 3'' collector and exhaust :biggthump
