Thread: SR20VE Dyno: Stock Cams vs. SR16VE Cams

Only if your concerned about dyno trophies. Its a tuning tool, makes no difference to my tunes if i have RPM or km down the bottom scale!

If you want to do the maths yourself, sr16ve box with 195/55/r15, 4th gear.

Also curious how high is the stupid cr

That was my goal, just gain some mid and high end without spending too much and having good fuel economy, maybe I won't be doing 13 second passes but a mid 14's full trim and be around 185whp would be perfect for my daily driven car.

I'll just go with my 20VE cams at the moment, if Somebody's willing to take the 16VE's then I could go over a N1 set

not exactly what you asked but... not back to back but same motor, same set up

just different times

both tuned

sr16ve: +3, -5

n1: 0, -3

i have since adjusted n1 cams settings

sr16ve: blue

n1: red



peace

why do we keep referring to low end?

who races down low, say below 5000rpm?

peace

Because low end inertia affects engine torque from every rpm above it.

Affecting horsepower. This is only really relative to dyno figures. Real world situations wont will rarely simulate ramp acceleration on a dyno.

Thanks, NiZmo. Good information.

Exactly, in fact, the few times I've been at the track I didn't want to be below 6k. For DD is another story, then I wish we had variable valve timing. But who cares we are not doing this to drive these things on the streets... right?

For road racing it depends on what track you are on & what gear is optimal for for each turn. If you are doing the 1/4 low end probably won't be a factor since it's balls to the walls but in road racing that's a whole 'nother story. SR guru Mike Kojima isn't too fond of the VE fully bolted on the road course. In his words, "no torque". Hell if I didn't have to downshift to stay in my powerband at critical points I could make up lots of time & concentrate on driving more.

Cheers, he does prefer the DE hands down for his application and I agree. The DE is more sensible for the application, imho, also.
